Of the Agreement

Driscoll Ranch Demolition

ARTICLE ONE

GENERAL PROJECT INFORMATION

A. General These Supplemental Conditions provide project-specific supplementary information and Supplemental Conditions to the General Conditions of the Agreement. These Supplemental Conditions are Contract Documents and address site specific factors relevant to execution of the Work for the Driscoll Ranch Demolition project (“Demolition Project” or “Project”). These Supplemental Conditions shall supersede any conflicting General Conditions. Where a portion of the General Conditions is altered by these Supplemental Conditions, the unaltered portions of the General Conditions shall remain in effect. Under no circumstances does the information herein override any of the Terms and Conditions set forth in the Agreement, nor alleviate the Contractor from executing the work in strict conformance with the Contract Documents. B. Project Description

The purpose of this project is to perform remediation, demolition and limited site restoration at the Driscoll Ranch, located within the La Honda Creek Open Space Preserve (“Preserve”), as fully described within the demolition project Contract Documents. Refer to on the Plan Sheets Protected species are active in this region, including the California red-legged Frog (RLF) and the Western Pong Turtle (WPD). The District will provide the contractor training at the project kick off to help staff identify and avoid any potential interaction with protected species, as further described below in Article Four, paragraph J. The contract must first demolish the Wool Ranch House, then the Upper Folger Ranch structures (including the Water Tank), before proceeding in any order to the Guerra Zanoni Ranch, Ray’s Ranch, or Lower Folger Ranch. C. Site Information


Page 4 of 8

Environmental Compliance The potential environmental impacts for the proposed work at Driscoll Ranch were evaluated in the La Honda Creek Master Plan Initial Study / Mitigated Negative Declaration (IS/MND) prepared under California Environmental Quality Act (CEQA). The Contractor will be required to complete all work in strict compliance with the MMRP (see Exhibit 1). All of the structures may contain special status species that require removal and clearance from qualified biologists. The District will coordinate the biological work in cooperation with the contractor. If the biologist is unable to remove and clear the species at the anticipated time, the District will notify the contractor’s project manager. The contractor will adjust the work plan to demolish other structures that have received clearance at no cost to the District. No change orders will be considered by the District for minor work stoppages necessary to remove species. The contractor should incorporate the costs of any delays into the basebid. Hazardous Materials Hazardous materials are present in the structures and pesticide compounds and petroleum hydrocarbons are present into certain soils. Hazardous materials abatement and remediation for the structures is covered in the report and specs by SCA Environmental (See Remediation Workplan and Survey). The chemical compounds found in the soils are discussed in the Soil Management Plan by Northgate Environmental Management. In particular, the corral area across from WR-4 is known to contain compounds potentially hazardous to worker health if the proper procedures are not followed. While no grading or demolition work within that area is part of this project, demolition and grading near the area should follow the same procedures. See Exhibit 2. These procedures include standard dust control measures and regular watering. The contractor shall take care to minimize soil disturbance to the maximum extent feasible in these area. Site Utilities There is no live electrical services to any of the structures (refer to PG&E disconnect letters, Exhibit 3). Contractor should be aware that there is live overhead high voltage lines between existing poles on site. Water is not available on site. The Contractor shall be responsible for providing all water on site for dust control. The Contractor shall provide temporary bathroom facilities as needed. Contractor shall be responsible for providing any temporary electrical service, if required, for its work on site. There is no telephone service at the site. Cellular service may be limited, dependent upon location on site and contractor’s cellular service provider. Propane tanks are present at each of the ranches. They should be assumed to be full and the contractor shall avoid them. Midpen will coordinate with Amerigas to properly dispose them. Access The Driscoll Ranch area within the La Honda Creek Preserve is accessed directly off Highway 84. Ray’s Ranch, Guerra-Zanoni, and Wool Ranch are accessed off Sears Ranch Road through gate LH11. Sears Ranch Road is a mostly unimproved dirt road on District property and a paved road for a short portion as it connects to Highway 84. An elementary school is located along Sears Ranch Road near to the property boundary. Extreme caution is required of the contractor along the public road near the Elementary school. The Folger Ranch property is accessed off Highway 84 on an unnamed gate via an improved dirt road through gate LH13.


Page 5 of 8

Accessing the Wool Ranch requires crossing a 20’ wide railcar bridge without railings or guardrails. It was rated by an engineer as having a carrying capacity of 40,000lbs in 2013, though it has likely degraded since that time. The Contractor will make its own determination about the load-carrying ability of the bridge and will assume all risk associated with moving equipment through this area. See Exhibit 4 for the Engineer’s Report and pictures of equipment that have recently crossed the bridge. The demolitions occur around and near an active cattle grazing operation. All gates must be left closed after being opening in order to prevent cows from getting out. See Exhibit 6 for Cow Safety Tips.

CONTRACT DOCUMENTS

2.1 Contract Documents Defined. Contract Documents shall mean these General Conditions, Supplemental Conditions, the Agreement with all Exhibits, and the project Specifications, Drawings, and all Addenda, Clarifications and Modifications incorporated herein by reference or listed in the Agreement, which together constitute the "Contract Documents" and represent the entire, integrated Agreement as to the Work contracted for between the parties. It supersedes all prior negotiations, representations or agreements, whether written or oral.


2.2 Intent Of Contract Documents. The intent of the Contract Documents is for the Contractor to provide, for not more than the contract Sum, all labor, supervision, materials, water, power, fuel, tools, plant, equipment, transportation and other items as may be necessary or appropriate for proper execution of the Work (except to the extent expressly provided otherwise in the Contract Documents). The Contract Documents are complementary, and what is shown within one shall be as binding as if shown within all. For example, anything referenced in the Specifications and not shown on the Drawings, or shown in the Drawings and not referenced in the Specifications, shall be of like effect as if shown or referenced in both.

2.3 General Specifications. In the event the Specifications or any directions given by the

District Representative pursuant to the Contract Documents require materials or other Work for which no detailed specifications are provided, the following general specifications shall apply:

The materials shall conform to the usual standards for first-class materials or article of the kind required with due consideration of the use to which they are to be put. Work shall conform to the usual standards for first-class work of the kind required, and shall be subject to the approval of the District Representative.

2.3.1Specification References. Any material or method specified by reference to the number, symbol, or title of a specific standard such as a Commercial Standard, a Federal Specification, a trade association standard or similar standards, shall comply with the requirements in the latest revision thereof, including any amendments or supplements thereto in effect on the date of Request for Bids, except as limited as to type, class, or grade or modified in such reference.

2.4 Discrepancies, Errors And Omissions. The Contract Documents are not complete in

every detail and in some cases may show only the purpose and intent. Contractor shall not avail itself of any manifest error, omission, discrepancy or ambiguity in the Contract Documents, or in the instructions given or in work provided by others. Contractor shall notify the District Representative in writing immediately upon the discovery of any such error, omission, discrepancy or ambiguity and the District Representative shall address the matter within a reasonable period of time, issuing a Clarification or Modification if appropriate. In the event of a discrepancy between documents, the most restrictive requirement shall govern. If Contractor proceeds with any Work-related activity involving an error, omission, discrepancy or ambiguity which Contractor knew of or reasonably should have known of, without first giving such notice, Contractor shall be responsible for all defects, delays, damages, and additional cost to District arising from or relating thereto, including without limitation all costs of correction, inspection testing, supervision and Project administration.

2.5 Division Of Work. The organization of the Specifications and arrangement of the

Drawings shall not control Contractor in dividing the Work among subcontractors or in establishing the extent of Work to be performed by any trade. Similarly, any table of contents, titles and headings contained in the Contract Documents are provided solely to facilitate reference to various provisions of the Contract Documents and shall in no way affect or limit the interpretations of the provisions to which they refer, or be construed as


a proposed segregation of the various units of the Work. Contractor shall arrange, divide and delegate its Work in conformance with sound trade practices, and shall be solely responsible for the division of the Work and establishment of subcontractor limits and scopes of work.

2.6 Clarifications. The District Representative may issue Clarifications to Contractor as

necessary or desirable to clarify requirements of the Contract Documents. Contractor shall request a clarification from the District Representative through a Request for Information (RFI) if Contractor or any Subcontractor believes that (a) any Work is not sufficiently detailed or explained in the Drawings and Specifications, (b) there is a conflict between the Drawings and Specifications, (c) there is a conflict between the Drawings and/or Specifications and field conditions, or (d) any other questions arise that require direction from the District Representative. Prior to submitting and RFI, Contractor shall complete a thorough review of the Contract Documents and inspect the Site to confirm that the grounds for an RFI exist.

2.7 “For Construction” Contract Documents. District shall furnish Contractor with one

hard copy and five (5) CD copies of the final “For Construction” Contract Documents, including Plans, Specifications and any Addenda.

2.8 Ownership And Use Of Documents. All Plans, Specifications, Models, and Samples

furnished to Contractor are the property of District. Plans, Specifications, Models, and Samples are not to be used by Contractor on any other work. All such Plans, Specifications, Models, and Samples shall be returned to District upon request and in any event at the end of the Term unless otherwise directed by District Representative.

District reserves the right to occupy or use any part, parts, or the entirety of the Work when District Representative deems it safe. The exercising of this right shall in no way constitute an acceptance of any part of the Work, nor shall it in any way affect the dates and times when payments become due Contractor; nor shall it in any way prejudice District's rights in the Contract. The Contract shall be deemed completed only when District Representative, in writing, accepts all the Work contracted for. 4.6.6Field Office. If a job site office is used, District Representative must approve the facility and its location before installation. District makes no representations as to the feasibility of access to the Work area for a job site office or secured storage facility due to the nature of the site which may hinder or prevent such transportation.

The District reserves the right to make such alterations, deviations, additions to, or deletions from, the Plans and Specifications, including the right to increase or decrease the quantity of any item or portion of the work, or to delete any item or portion of the work, as may be deemed by the District Representative to be necessary or advisable, and to require such extra work as may be determined by the District Representative to be required for the proper completion or construction of the whole Work. If District Representative determines that a change ordered by District caused an increase or decrease in Contractor's costs or time required for completing the Contract, appropriate adjustments to the Contract price and/or time shall be made. Contractor shall not be entitled to any compensation for extra work or time to finish the Contract without a written Change Order from District Representative. Failure to agree on an adjustment of the Contract price or time extension shall not excuse


Contractor from proceeding with the Work as changed. 7.1.2Form of Change Order. The Contractor or District Representative may request changes to the work. Once proposed changes have been reviewed and approved, the Contractor shall submit a Change Order. Proposed Change Order Requests and Change Orders shall be completed using the forms attached hereto and incorporated herein as Exhibits 4 and 5. Once Change Order is approved by the District Representative, payment in accordance with the provisions as to compensation set forth therein shall constitute full compensation for all work included therein or required thereby. Any such changes will be set forth in a Change Order, in the form attached hereto and incorporated herein as Exhibit 5, which specifies, in addition to the Work to be done in connection with the change made, adjustment of contract time, if any, and the basis or amount of any additional compensation for such Work. No Change Order shall be effective until approved in writing as set forth herein by the District Representative. Upon receipt of an approved Change Order, the Contractor shall proceed with the ordered Work. If ordered in writing by the District Representative, the Contractor shall proceed with the Work so ordered prior to actual receipt of an approved Change Order. In such cases, the District Representative will, as soon as practicable, issue an approved Change Order for such work and the provisions hereof regarding "Procedure and Protest" shall be fully applicable to such subsequently issued Change Order. An approved Change Order shall supersede a proposed, but unapproved, Change Order covering the same Work. 7.1.3When the compensation for an item of work is subject to adjustment under these provisions, the Contractor shall, upon request, furnish the District Representative with adequately detailed cost data for such item of work. If the Contractor requests an adjustment in compensation for an item of work as provided, such cost data shall be submitted with his request. 7.1.4Procedure and Protest. A Change Order approved by the District Representative may be issued to the Contractor at any time. Should the Contractor disagree with any terms or conditions set forth in an approved Change Order that he has not executed, he shall submit a written protest to the District Representative within fifteen (15) days after the receipt of such approved Change Order. An un-protested approved Change Order will be considered an executed Change Order as that term is used herein.

(a) The protest shall state the points of disagreement, and, if possible, the contract specification references, quantities, and costs involved. If a written protest is not submitted, payment will be made as set forth in the approved Change Order and such payment shall constitute full compensation for all work included therein or required thereby. (b) Where the protest concerning an approved Change Order relates to compensation, the compensation payable for all Work specified or required by said Change Order to which such protest relates will be determined as provided herein. The Contractor shall keep full and complete records of the cost of such Work and shall permit the District Representative to have such access thereto as may be necessary to assist in the determination of the compensation payable for such Work. (c) Where the protest concerning an approved Change Order relates to the adjustment of contract time for the completion of the work, the time to be allowed thereof will be determined as provided for in Paragraph 4.13.3, "Liquidated Damages for Delay".

7.1.5Eliminated Items. Should any contract item of the Work be eliminated in its


entirety, in the absence of an executed Change Order covering such elimination, payment will be made to the Contractor for actual costs incurred in connection with such eliminated contract item if incurred prior to the date of notification in writing by the District Representative of such elimination. If acceptable material is ordered by the Contractor for the eliminated item prior to the date of notification of such elimination by the District Representative, and if orders for such material cannot be canceled, it will be paid for at the actual cost to the Contractor. In such case, the material paid for shall become the property of the District and the actual cost of any further handling by Contractor will be reimbursed. If the material is returnable to the vendor, and if the District Representative so directs, the material shall be returned and the Contractor will be paid for the actual cost of charges made by the vendor for returning the material and the actual cost of handling such returned material reimbursed. The actual costs or charges to be paid by the District to the Contractor as provided for herein will be computed in the same manner as if the Work were to be paid for on a force account basis.

7.2 Changes In Character Of Work. If an ordered change in the Plans or Specifications materially changes the character of the Work of a contract item from that on which the Contractor based his bid price, and if the change increases or decreases the actual unit cost of such changed item as compared to the actual or estimated actual unit cost of performing the Work of said item in accordance with the Plans and Specifications originally applicable thereto, in the absence of an executed contract change order specifying the compensation payable, an adjustment in compensation thereof will be made in accordance with the following: 7.2.1The basis of such adjustment in compensation will be the difference between the actual unit cost to perform the Work of said item or portion thereof involved in the change as originally planned and the actual unit cost of performing the Work of said item or portion thereof involved in the change, as changed. Actual unit costs will be determined by the District Representative in the same manner as if the Work were to be paid for on a force account basis; or such adjustment will be as agreed to by the Contractor and the District Representative. Any such adjustment will apply only to the portion of the Work of said item actually changed in character. At the option of the District Representative, the Work of said item or portion of item that is changed in character will be paid for by force account. 7.2.2If the compensation for an item of Work is adjusted under this Section, the costs recognized in determining such adjustment shall be excluded from consideration in making an adjustment for such item of work under the provisions of the paragraph titled "Increased or Decreased Quantities." 7.2.3Failure of the District Representative to recognize a change in character of the Work at the time the approved contract change order is issued shall not be construed as relieving the Contractor of the duty and responsibility of filing a written protest within the fifteen (15) day limit as provided in the paragraph titled "Procedure and Protest."

7.3 Extra Work. New and unforeseen Work will be classed as Extra Work when

determined by the District Representative that such Work is not covered by any of the various items for which there is a bid price or by combinations of such items.

EXHIBIT D31: Mitigation Monitoring and Reporting Plan

MITIGATION MONITORING PROGRAM CONTENTS This mitigation monitoring program (MMP) includes a brief discussion of the legal basis and purpose of the program, a key to understanding the monitoring matrix, discussion and direction regarding noncompliance complaints, and the mitigation monitoring matrix itself. LEGAL BASIS AND PURPOSE OF THE MITIGATION MONITORING PROGRAM Public Resources Code (PRC) 21081.6 requires public agencies to adopt mitigation monitoring or reporting programs whenever certifying an environmental impact report or mitigated negative declaration. This requirement facilitates implementation of all mitigation measures adopted through the California Environmental Quality Act (CEQA) process. MONITORING MATRIX The following page provides a table identifying the mitigations incorporated into the La Honda Creek Open Space Preserve Master Plan (the project). These mitigations are reproduced from the Mitigated Negative Declaration for the project. The columns within the tables have the following meanings: Number: The number in this column refers to the Initial Study section where the mitigation

is discussed. Mitigation: This column lists the specific mitigation identified within the Mitigated Negative

Declaration. Timing: This column identifies at what point in time, review process, or phase the

mitigation will be completed. The mitigations are organized by order in which they appear in the Mitigated Negative Declaration.

Who will This column references the District department that will ensure implementation of verify? the mitigation. Verification: This column will be initialed and dated by the individual designated to confirm

implementation. NONCOMPLIANCE COMPLAINTS Any person or agency may file a complaint asserting noncompliance with the mitigation measures associated with the project. The complaint shall be directed to the District’s General Manager in written form, providing specific information on the asserted violation. The General Manager shall cause an investigation and determine the validity of the complaint; if noncompliance with a mitigation measure has occurred, the General Manager shall cause appropriate actions to remedy any violation. The complaint shall receive written confirmation indicating the results of the investigation or the final action corresponding to the particular noncompliance issue.


MITIGATION MEASURES MATRIX The following mitigation measures will be incorporated into the project planning and execution:

Number Mitigation Timing Who Will Verify? Verification (Date & Initials)

Mitigation in Section III Air Quality

Mitigation Measure 3.3-1

The District shall require all its construction contractors to implement the following basic construction mitigation measures. Some, but not all of these measures are similar to the dust control measures required by the Environmental Protection Guidelines which directly incorporate the Mitigation Measures of the San Mateo Coastal Annexation EIR. (The measures below provide updated consistency with BAAQMD regulations.)

Basic Construction Mitigation Measures

⟩ All exposed and un-compacted surfaces (e.g., staging areas, soil piles, and graded areas,) shall either be watered two times per day or covered with mulch, straw, or other dust control cover.

⟩ All haul trucks transporting soil, sand, or other loose material off-site shall be covered.

⟩ All visible mud or dirt track-out onto adjacent public roads shall be collected and removed at least once per day. The use of dry power sweeping is prohibited.

⟩ All vehicle speeds on unpaved roads shall be limited to 15 miles per hour (mph).

⟩ All roadways, driveways, and sidewalks to be paved shall be completed as soon as possible. Building pads shall be laid as soon as possible after grading unless seeding, dust control covers, or soil binders are used.

During construction

MROSD Operations (Resource Specialist) with Planning PM



⟩ Idling times shall be minimized either by shutting equipment off when not in use or reducing the maximum idling time to 5 minutes (as required by the California airborne toxics control measures (ATCM) Title 13, Section 2485 of California Code of Regulations). Clear signage shall be provided for construction workers at all access points.

⟩ All construction equipment shall be maintained and properly tuned in accordance with manufacturer’s specifications. All equipment shall be checked by a certified mechanic and determined to be running in proper condition prior to operation.

⟩ Post a publicly visible sign with the telephone number and person to contact at the Lead Agency regarding dust complaints. This person shall respond and take corrective action within 48 hours. BAAQMD’s phone number shall also be visible to ensure compliance with applicable regulations.

Mitigation in Section IV Biological Resources:

BIO-1 Conduct Special-status Plant Surveys, Implement Avoidance and Mitigation Measures, or Provide Compensatory Mitigation.

The District shall utilize qualified District staff or a contractor to conduct protocol-level preconstruction special-status plant surveys for all potentially occurring species within the project footprint that has not previously been surveyed. Prior to ground-disturbance or vegetation management in potentially suitable habitat, surveys shall be conducted during the appropriate blooming period when they are most readily identifiable in accordance with Protocols for Surveying and Evaluating Impacts to Special Status Native Plant Populations and Natural Communities (DFG 2009). If no special-status plants are found during focused surveys, the findings shall be documented in a letter report, and no further mitigation shall be required.

If special-status plant populations are present in the project footprint, the District shall determine if the population can be avoided by adjusting the project design. The District will locate new trails, new roads, or other new

Preconstruction MROSD Operations Dept. (Resource Specialist) with Planning PM



facilities to avoid impacts to the extent feasible.

If the impact to special-status plants cannot be avoided, the District shall consult with DFG and USFWS, as appropriate depending on species status, to determine the appropriate measures to ensure no net loss of occupied habitat or individuals. These measures may include preserving and enhancing existing populations, creation of off-site populations on project mitigation sites through seed collection or transplantation, and/or restoring or creating suitable habitat in sufficient quantities to achieve the no-net-loss standard.

BIO-2a Protection and Compensation Measures for California Red-legged Frog,

The District or its contractor will avoid impacts to California red-legged frog by avoiding aquatic and riparian habitat by at least 200-feet to the extent feasible.

If project activities are to occur in aquatic habitat, qualified District staff or a contractor shall determine if suitable habitat for California red-legged frog (e.g., streams with slow moving water or ponds) is present using USFWS’ California Red-legged Frog Habitat Site Assessment Data Sheet (USFWS 2005, Appendix D) and following Equipment Decontamination Procedures (USFWS 2005, Appendix B) to minimize the spread of pathogens that may be transferred as a result of surveys. If the habitat requirements for California red-legged frog are not met, then no further mitigation shall be required.

If suitable aquatic habitat for California red-legged frog could be affected, the District will consult with the U.S. Fish and Wildlife Service (USFWS) and comply with the requirements of the Endangered Species Act (ESA). Because potential impacts to aquatic habitat for California red-legged frog may also require a Section 404 permit from the USACE (see Discussion under “C” below and Mitigation Measure BIO 6), consultation would likely occur under Section 7 of the ESA.

The District shall ensure the no net loss of California red-legged frog habitat

Prior to and during construction activities.

MROSD Operations Dept. (Resource Specialist) with Planning PM



occurs. Aquatic habitat that is disturbed during construction shall be restored to its pre-project condition. If permanent loss of habitat occurs, habitat restoration or enhancement shall occur elsewhere on District land as compensatory mitigation.

⟩ The District will implement the following minimization measures to protect California red-legged frog during construction activities in streams with slow moving water or ponds:

⟩ At least 15 days prior to the onset of activities, the applicant or project proponent shall submit the name(s) and credentials of biologists who would conduct activities specified in the following measures. No project activities shall begin until proponents have received written approval from USFWS that the biologist(s) is qualified to conduct the work.

⟩ A USFWS-approved biologist shall survey the work site two weeks before the onset of activities. If California red-legged frogs, tadpoles, or eggs are found, the approved biologist shall contact USFWS to determine if moving any of these life-stages is appropriate. In making this determination USFWS shall consider if an appropriate relocation site exists. If USFWS approves moving animals, the approved biologist shall be allowed sufficient time to move California red-legged frogs from the work site before work activities begin. Only USFWS-approved biologists shall participate in activities associated with the capture, handling, and monitoring of California red-legged frogs.

⟩ Before any construction activities begin on a project, a USFWS-approved biologist shall conduct a training session for all construction personnel. At a minimum, the training session shall include a description of the California red-legged frog and its habitat, the importance of California red-legged frog and its habitat, the general measures that are being implemented to conserve the California red-legged frog as they relate to the project, and the boundaries within which the project may be accomplished. Brochures, books, and



briefings may be used in the training session, provided that a qualified person is on hand to answer any questions.

⟩ A USFWS-approved biologist shall be present at the work site until such time as all removal of California red-legged frogs, instruction of workers, and habitat disturbance have been completed. After this time, the contractor or permittee shall designate a person to monitor on-site compliance with all minimization measures. The USFWS-approved biologist shall ensure that this individual receives training outlined above in measure 3 and in the identification of California red-legged frogs. The monitor and the USFWS-approved biologist shall have the authority to halt any action that might result in impacts that exceed the levels anticipated by USACE and USFWS during review of the proposed action. If work is stopped, USACE and USFWS shall be notified immediately by the USFWS-approved biologist or on-site biological monitor.

⟩ During project activities, all trash that may attract predators shall be properly contained, removed from the work site and disposed of regularly. Following construction, all trash and construction debris shall be removed from work areas.

⟩ All fueling and maintenance of vehicles and other equipment and staging areas shall occur at least 20 meters from any riparian habitat or water body. USACE and permittee shall ensure contamination of habitat does not occur during such operations. Prior to the onset of work, USACE shall ensure that the permittee has prepared a plan to allow a prompt and effective response to any accidental spills. All workers shall be informed of the importance of preventing spills and of the appropriate measure to take should a spill occur.

⟩ A USFWS-approved biologist shall ensure that the spread or introduction of invasive exotic plant species shall be avoided to the maximum extent possible. When practicable, invasive exotic plants in



the project areas shall be removed.

⟩ Project sites shall be revegetated with an appropriate assemblage of native riparian wetland and upland vegetation suitable for the area. A species list and restoration and monitoring plan shall be included with the project proposal for review and approval by USFWS and USACE. Such a plan must include, but not be limited to, location of the restoration, species to be used, restoration techniques, time of year the work will be done, identifiable success criteria for completion, and remedial actions if the success criteria are not achieved.

⟩ Stream contours shall be returned to their original condition at the end of the project activities, unless consultation with USFWS has determined that it is not beneficial to the species or feasible.

⟩ The number of access routes, number and size of staging areas, and the total area of the activity shall be limited to the minimum necessary to achieve the project goal. Routes and boundaries shall be clearly demarcated, and these areas shall be outside of riparian and wetland areas. Where impacts in these staging and access routes, restoration shall occur as identified in measures 8 and 9 above.

⟩ Work activities shall be completed between May 1 and November 1. Should the proponent or applicant demonstrate a need to conduct activities outside this period, USACE may authorize such activities after obtaining the USFWS’ approval.

⟩ To control erosion during and after project implementation, the applicant shall implement best management practices, as identified by the appropriate Regional Water Quality Control Board.

⟩ If a work site is to be temporarily dewatered by pumping, intakes shall be completely screened with wire mesh not larger than five millimeters to prevent California red-legged frogs from entering the pump system. Water shall be released or pumped downstream at an appropriate rate



to maintain downstream flows during construction. Upon completion of construction activities, any barriers to flow shall be removed in a manner that would allow flow to resume with the least disturbance to the substrate.

⟩ USFWS-approved biologist shall permanently remove, from the project area, any individuals of exotic species, such as bullfrogs, crayfish, and centrarchid fishes, to the maximum extent possible. The permittee shall have the responsibility to ensure that their activities are in compliance with the California Fish and Game Code.

BIO-2b Preconstruction Surveys and Protection Measures for Western Pond Turtles

The District or its contractor will avoid impacts to western pond turtle by avoiding aquatic and riparian habitat by at least 200-feet to the extent feasible.

Qualified District staff or contractor shall conduct a pre-construction survey for western pond turtles no more than 30 days prior to construction in suitable aquatic habitats and upland habitat within the project corridor/footprint, including stream crossings, drainage ditches, and culverts.

If the species is found near any proposed construction area, impacts on individuals and their habitat shall be avoided to the greatest extent feasible.

If occupied habitat can be avoided, an exclusion zone shall be established around the habitat, and temporary exclusion fencing shall be installed around a buffer area determined by the qualified District staff or contractor with “Sensitive Habitat Area” signs posted and clearly visible on the outside of the fence.

If avoidance is not possible and the species is determined to be present in work areas, the qualified District staff or contractor, with approval from CDFG, may capture turtles prior to construction activities and relocate them to





nearby, suitable habitat a minimum of 300 feet downstream from the work area. Exclusion fencing should then be installed, if feasible, to prevent turtles from reentering the work area. For the duration of work in these areas, the qualified District staff or contractor should conduct monthly follow-up visits to monitor effectiveness.

BIO-2c Preconstruction Surveys and Protection Measures for San Francisco Garter Snake

General Impact Avoidance Measures

If an incidental sighting of San Francisco garter snake is reported in the Preserve, either from District staff or recreational visitor to the Preserve, the District shall evaluate the validity of the sighting and take precautionary actions to ensure that the individual is protected. Measures shall include:

⟩ Conducting focused surveys in the area of the reported sighting to delineate boundaries of occupied and potentially occupied areas

⟩ Avoiding disturbance within 660 feet of occupied aquatic and riparian habitat to the extent feasible

⟩ Based on survey results and potential habitat, the District may restrict certain types of activities, or close the area to specific uses as appropriate

Impact Avoidance Measures for Construction Projects

Qualified District staff or a contractor shall conduct a pre-construction survey for San Francisco garter snake no more than 30 days prior to construction in suitable aquatic habitats and adjacent upland habitat within the project footprint.

If the species is found near any proposed construction area, work shall cease immediately and the District shall contact USFWS and California Department

During operation and prior to construction activities.




of Fish and Game within 24 hours to develop appropriate conservation measures to avoid and minimize impacts.

BIO-3 Preconstruction Surveys and Protection Measures for Bat Roosts in Buildings

Surveys for roosting bats on the project site will be conducted by a qualified District staff or contractor. Surveys will consist of a daytime pedestrian survey looking for evidence of bat use (e.g., guano) and/or an evening emergence survey to note the presence or absence of bats. The type of survey will depend on the condition of the buildings. If no bat roosts are found, then no further study is required. If evidence of bat use is observed, the number and species of bats using the roost will be determined. Bat detectors may be used to supplement survey efforts, but are not required.

If roosts of pallid or Townsend’s big-eared bats are determined to be present and must be removed, the bats will be excluded from the roosting site before the facility is removed. A program addressing compensation, exclusion methods, and roost removal procedures will be developed in consultation with DFG before implementation. Exclusion methods may include use of one-way doors at roost entrances (bats may leave but not reenter), or sealing roost entrances when the site can be confirmed to contain no bats. Exclusion efforts may be restricted during periods of sensitive activity (e.g., during hibernation or while females in maternity colonies are nursing young). The loss of each roost (if any) will be replaced in consultation with DFG and may include construction and installation of bat boxes suitable to the bat species and colony size that was excluded from the original roosting site. Roost replacement will be implemented before bats are excluded from the original roost sites. The District has successfully constructed bat boxes elsewhere that have subsequently been occupied by bats. Once the replacement roosts are constructed and it is confirmed that bats are not present in the original roost site, the structures may be removed or sealed.

In the case of renovation work, renovations will be done in as concentrated a time period as possible and will be timed to minimize disturbance to bat roosts

Prior to demolition and/or renovation activities, and during renovation.




as recommended by a bat expert. Renovations will be done in a manner that will promote the continued use of the structure by bats whenever feasible.

BIO-4a Preconstruction Surveys and Protection Measures for Raptors and Other Nesting Birds

To minimize potential disturbance to nesting birds, project activities, including vegetation removal and building demolition, watershed habitat management, and vegetation and forest management, shall occur during the non-breeding season (September 16-February 14), unless it is not feasible to do so, in which case the following measures shall also be applied.

During trail construction, road improvements, and other activities, removal of trees greater than 6 inches dbh shall be limited to the greatest degree possible.

If construction activity is scheduled to occur during the nesting season (February 1 to August 15), The District shall utilize qualified District staff or contractor to conduct preconstruction surveys and to identify active nests on and within 500 feet of the project site that could be affected by project construction. The surveys shall be conducted no less than 14 days and no more than 30 days before the beginning of construction in a particular area. If no nests are found, no further mitigation is required.

If active nests are found, impacts on nesting raptors and songbirds shall be avoided by establishment of appropriate buffers around the nests. No project activity shall commence within the buffer area until a qualified District staff or contractor confirms that any young have fledged or the nest is no longer active. A 500-foot buffer around raptor nests and 50-foot buffer around songbird nests are generally adequate to protect them from disturbance, but the size of the buffer may be adjusted by a qualified District staff or contractor in consultation with DFG depending on site specific conditions. For trail





construction, use of non-power hand-tools may be permitted within the buffer area if the behavior of the nesting birds would not be altered as a result of the construction. Monitoring of the nest by a qualified District staff or contractor during and after construction activities will be required if the activity has potential to adversely affect the nest.

BIO-4b Avoidance of Nesting Habitat and Protection Measures for Marbled Murrelets

To minimize potential disturbance to marbled murrelets at potential nesting sites and traveling to coastal foraging areas, the following measures shall be implemented:

⟩ The District shall maintain a GIS-based map of potentially suitable habitat for marbled murrelets in the Preserve. A ¼ mile buffer around suitable habitat shall be identified and mapped.

⟩ No construction activities shall occur within potentially suitable habitat, associated buffer zones, or areas identified as old growth during the marbled murrelet breeding season (March 24 to September 15).

⟩ If volunteer or contract work is scheduled to occur during the marbled murrelet breeding season (March 24 to September 15) in forested areas of the Preserve, a qualified District staff or contractor shall review the project area and verify that the project activities would not occur within the area identified as potential habitat and buffer zone.

⟩ Within conifer forests on the Preserve, during the marbled murrelet breeding season (March 24 to September 15), noise generating construction activity shall be restricted to 2 hours after sunrise to 2 hours before sunset to minimize disturbance of potential nesting murrelets using forest habitat as a travel corridor between inland nesting and coastal habitat.





BIO-5 Protection and Compensation Measures for Anadromous Fish

The District or its contractor will avoid impacts to coho salmon and steelhead by avoiding stream habitat by at least 200-feet to the extent feasible.

If project activities are to occur in stream habitat, a qualified District staff or contractor shall determine if suitable habitat for anadromous fish would be affected by the activity, including downstream effects. Examples could include activities associated with bank stabilization or installation of stream crossing footings (etc.) within the ordinary high water mark (OHWM). If the habitat for anadromous fish would not be affected, then no further mitigation shall be required.

If suitable habitat for anadromous fish would be affected by the project activity, the District will consult with the National Marine Fisheries Service (NMFS) to comply with the requirements of the Endangered Species Act (ESA) and California Department of Fish and Game (DFG) to comply with the requirements of the California Endangered Species Act (CESA). Because potential impacts to stream habitat for these anadromous fish may also require a Section 404 permit from the USACE (see Discussion under “C” below and Mitigation Measure BIO 6), consultation would likely occur under Section 7 of the ESA. The proposed projects may qualify for ESA compliance by using the programmatic Biological Opinion for Anadromous Fish issued to USACE for specific fisheries restoration projects (NMFS 2006).

The District shall ensure the no net loss of coho salmon and steelhead habitat occurs. Aquatic habitat that is disturbed during construction shall be restored to its pre-project condition. If permanent loss of habitat occurs, habitat restoration or enhancement shall occur elsewhere on District land as compensatory mitigation.

⟩ The District will implement the following minimization measures to protect aquatic habitat during construction activities in streams:

⟩ Project sites shall be monitored by a qualified District staff or

Prior to, during, and following completion of construction activities.




contractor during construction to prevent adverse and unforeseen effects to listed salmonids. The qualified staff or contractor shall monitor work activities and instream habitat a minimum of three times per week during construction for the purpose of identifying and reconciling any condition that could adversely affect salmonids or their habitat. The District staff or contractor shall have the authority to cease construction activities in order to resolve any unanticipated adverse impact resulting from construction.

⟩ A monitoring report shall be provided to NMFS and DFG following the completion of construction within 120 calendar days following the completion of the construction phase of each restoration project. The report shall include the number and approximate size (mm) of listed salmonids captured and removed; any effect of the proposed action on listed salmonids; and photographs taken before, during, and after the activity from photo reference points.

⟩ A spill prevention plan shall be in place prior to construction and shall be reviewed and approved by NMFS and DFG prior to construction.

⟩ The District shall review and incorporate the minimization and avoidance measures, as proposed by USACE, NMFS, and/or DFG, prior to final project design submittal and construction. Construction crews and the qualified staff or contractor shall have a copy of these measures on site during project activities.

⟩ Restoration projects shall not result in the introduction of anadromous salmonids into nonnative habitats. Fish passage enhancement actions, that facilitate anadromous salmonid migration into stream reaches without any prior historical access, are not permitted.

⟩ Sediment minimization measures shall apply to large woody debris (LWD) placement actions. Root wads placed instream to enhance salmonid habitat shall be largely free of fine sediment prior to



placement.

⟩ NMFS and/or DFG may place additional site specific conditions on any restoration project in order to protect listed salmonids or their critical habitat from otherwise unforeseen adverse circumstances. USACE are expected to incorporate these additional site specific conditions into their permits.

BIO-6 Wetland Minimization and Compensation Measures

The District will implement the following measures to minimize impacts to wetlands and other waters of the U.S.:

⟩ Where wetlands or other Waters could be affected by trail improvements, bank stabilization, or other activities, a preliminary wetland delineation shall be submitted to USACE for verification. The wetlands may also be subject to DFG regulation under Section 1602 of the Fish and Game Code. No grading, fill, or other ground disturbing activities shall occur until all required permits, regulatory approvals, and permit conditions for effects on wetland habitats are secured.

⟩ If the wetlands are determined to be subject to USACE jurisdiction, projects such as small bank stabilization projects, restoration activities, or trail or road crossings may qualify for a Nationwide Permit if certain criteria are met. For those wetlands that cannot be avoided, The District shall commit to replace, restore, or enhance on a “no net loss” basis (in accordance with USACE, RWQCB, and DFG) the acreage of all wetlands and other waters of the U.S. that would be removed, lost, and/or degraded with project implementation. Wetland habitat shall be restored, enhanced, and/or replaced at an acreage and location and by methods agreeable to USACE, RWQCB, and DFG, as appropriate, depending on agency jurisdiction, and as determined during the permitting processes.

Soil Management Plan 1 December 18, 2009 Driscoll Ranch La Honda, San Mateo County, California

1.0 INTRODUCTION

This Soil Management Plan (SMP) has been prepared on behalf of Midpeninsula Regional Open Space District (the District) for the Driscoll Ranch Property, located in La Honda, San Mateo County, California (the Site). This SMP documents current soil conditions and provides guidance for soil handling, disposal, or reuse procedures, including health and safety provisions for workers that might encounter contaminated soil. This SMP has been submitted to the California Regional Water Quality Control Board (RWQCB) for review and approval, per the RWQCB’s February 4, 2009 letter of approval of the Remedial Investigation (RI) Report (Northgate, 2008). The RWQCB letter is included as Appendix A.

1.1 Background

Driscoll Ranch includes more than 3,682 acres of land owned by the District (Figure 1). The District plans to incorporate Driscoll Ranch into the La Honda Creek Open Space Preserve (the Preserve). The primary objective of the Preserve is ecological habitat preservation. There will be limited recreational access to the Preserve via hiking, equestrian, and potentially biking trails. The District also plans to have a residence for District personnel. Additionally, continued cattle grazing, special events parking associated with the existing Driscoll Ranch Event Center, up to three residences, and limited equestrian and pedestrian use of the property by the tenant, Rudy Driscoll, is allowed under a Lease-Agreement. It is the District’s intent to manage residual contamination remaining on Driscoll Ranch while allowing safe public access to the property.

Previous environmental assessments (Erler and Kalinowski, Inc. [EKI], 2001 and 2005) identified the primary environmental concerns at Driscoll Ranch to be residual petroleum hydrocarbons (crude oil) associated with the operation of a former oil field, pesticides (primarily toxaphene and dieldrin) associated with the former ranch practice of spraying cattle in stock corrals, and residual gasoline and diesel associated with small above-ground storage tanks (ASTs) formerly used by Driscoll Ranch.

The RI performed by Northgate (Northgate, 2008) further characterized Site conditions, and determined appropriate site-specific target levels (SSTLs) for contaminants of interest (COI) consistent with the long-term use of the property as an open-space preserve. A human health risk assessment (HRA) was prepared as part of the RI Report. The HRA concluded that pesticide compounds and total petroleum hydrocarbons (TPH) are present in soil at levels for which recreational users, Ranch workers, and District staff may contact the soil without posing a health risk. However, maintenance and construction activities that cause disturbance to the impacted soil



must be performed in accordance with this Soil Management Plan and the Health and Safety Plan (Appendix B), as required by the RWQCB.

1.2 Purpose

The purpose of the SMP is to outline procedures to be utilized when handling impacted soil that may be encountered during routine or emergency maintenance or construction activities. There are five localized areas that contain residual chemicals within the Driscoll Ranch property that are subject to this SMP. These areas are shown on Figures 2 through 5. The five areas are briefly described below.

• In one localized area formerly used for cattle management (Corral #5), shallow soil at the site contains elevated levels of organochlorine pesticides (primarily toxaphene and dieldrin).

• In three areas associated with former oil exploration at the property (the Main Oil Field, the Tank Farm Area, and the Product Tank Area), TPH characterized primarily as crude oil (TPH-O) and the associated polycyclic aromatic hydrocarbon (PAH) dibenz(a,h)anthracene are present in soil.

• A small area formerly housing one above-ground diesel tank and one above-ground gasoline tank used during former ranching activities contains soil with TPH characterized as diesel (TPH-D) and gasoline (TPH-G).

1.3 Characteristics of Existing Soil

Surface and subsurface soils at the property contain elevated levels of TPH-O, TPH-D, TPH-G, dibenz(a,h)anthracene, toxaphene, or dieldrin, as described above. The SSTLs of these compounds that are approved by the RWQCB for soil in recreational land use areas are presented in Table 1. These SSTLs have been shown through a HRA to be protective of human health for recreational users of the property, Ranch workers, and District staff. Chemical testing performed during the RI indicates that actual chemical concentrations in most soil at the site are well below the SSTLs. However, chemical concentrations are above RWQCB environmental screening levels (ESLs, May 2008) for residential and/or general unrestricted land use areas.

The RI characterized environmental conditions at Driscoll Ranch to the extent necessary to evaluate potential impacts to human health and the environment caused by previous uses at the property for oil production and cattle ranching. The focus of the RI was on residual petroleum hydrocarbons in soil at an oil field that had been closed in the 1990s; residual pesticides from applications associated with cattle management prior to the 1990s; and the use of ASTs for fuel storage in association with ranching activities in the 1990s and early 2000s. Potential impacts to



the health of future workers and visitors were evaluated by performing a HRA and developing SSTLs for residual chemicals of interest. A recreational-use scenario was used as the basis for exposure assumptions in the HRA, which is considered appropriate and conservative for the anticipated future use of the property.

The sections below provide a summary of soil characteristics at each of the areas subject to this SMP. The RI Report provides details of soil characteristics, including graphical descriptions of the extent of residual contamination in each of the areas.

1.3.1 Main Oil Field Area

The investigation conducted in 2005 by EKI identified the presence of heavy distillate petroleum hydrocarbons in shallow soil in the vicinity of several abandoned oil production wells. The RI conducted in 2008 by Northgate further characterized the distribution and character of the petroleum hydrocarbons in the vicinity of two of the former well sites that had contained the highest concentrations of petroleum hydrocarbons. Results indicated that the extents of petroleum hydrocarbon contamination were limited both in depth (less than 10 feet) and aerial distribution (within a distance of approximately 20 feet from the former well sites). Additionally, analytical results and field observations confirmed that the petroleum hydrocarbons were highly weathered and degraded crude oil, lacking mobile or volatile constituents that could cause a threat to the environment or be a nuisance to future users of the property. Although two of the former well sites could not be accessed, it is reasonable to assume that conditions at those well sites would be similar to the well sites that were investigated by EKI in 2005 and by Northgate in 2008. The HRA concluded that residual petroleum hydrocarbons remaining at the well sites would not pose a health risk to future users of the property. TPH-O concentrations in soil averaged approximately 324 milligrams per kilogram (mg/kg) with a maximum concentration of 1,600 mg/kg, well below the SSTL of 19,000 mg/kg developed for a recreational use scenario. Other constituents were below RWQCB ESLs for residential use. Naturally occurring degradation processes likely will continue to reduce petroleum hydrocarbon concentrations in the soil over time.

1.3.2 Tank Farm Area

The investigation conducted in 2005 by EKI identified the presence of heavy distillate petroleum hydrocarbons in shallow soil in the vicinity of several former ASTs, collectively referred to as the Tank Farm Area, which had been used to store oil extracted from the oil field. The RI conducted by Northgate in 2008 further characterized the distribution and character of the



petroleum hydrocarbons in the vicinity of three of the AST sites that had contained the highest concentrations of petroleum hydrocarbons.

Results indicated that the extent of petroleum hydrocarbon contamination was widespread in the Tank Farm Area, and extended locally to a depth of 41 feet below ground surface (bgs) (in one soil boring), though more typically the contamination only extended to depths of 20 to 30 feet bgs. Concentrations generally were highest in shallow soil, and decreased with depth. Analytical results, results of petroleum hydrocarbon characterization, and field observations confirmed that the product was highly weathered and degraded crude oil.

The residual oil in the upper five to six feet of soil and bedrock lacked mobile and volatile constituents that could cause a threat to the environment or be a nuisance to future users of the property. The residual oil at deeper depths was also highly degraded, but exhibited different characteristics compared with the oil at shallower depths. It is likely that the deeper oil had weathered anaerobically rather than aerobically. Though the material contained a noticeable odor and registered a photoionization detector (PID) response in the field, laboratory analyses only identified relatively low levels of volatile constituents (ethylbenzene and xylenes) present in a small percentage of samples. Given the depth of the oil and its characteristics, it was concluded that the residual oil was unlikely to cause a threat to the environment or be a nuisance to future users of the property. The HRA concluded that residual petroleum hydrocarbons remaining at the former Tank Farm Area would not pose a health risk to future users of the property. TPH-O concentrations in soil averaged approximately 660 mg/kg with a maximum concentration of 7,600 mg/kg, well below the SSTL of 19,000 mg/kg developed for a recreational use scenario. Dibenz(a,h)anthracene concentrations averaged approximately 0.032 mg/kg with a maximum concentration of 0.069 mg/kg, also well below the SSTL of 1.2 mg/kg developed for a recreational use scenario. Other constituents were below RWQCB ESLs for residential use. Naturally occurring degradation processes likely will continue to reduce petroleum hydrocarbon concentrations in the soil over time.

1.3.3 Product Tank Area

The investigation conducted in 2005 by EKI identified the presence of heavy distillate petroleum hydrocarbons in shallow soil in the vicinity of several former ASTs, collectively referred to as the Product Tank Area, which had been used to store oil extracted from the oil field. Sampling results from the 2005 investigation were sufficient to evaluate the approximate distribution of petroleum hydrocarbons, so no further testing of the Product Tank Area was completed during the 2008 RI.



TPH-O concentrations in soil ranged from approximately 69 to 1,160 mg/kg, well below the SSTL of 19,000 mg/kg developed for a recreational use scenario. No other petroleum-related constituents were detected in the soil tested in this area. Naturally occurring degradation processes likely will continue to reduce petroleum hydrocarbon concentrations in the soil over time.

1.3.4 Stock Corral #5

The investigation conducted in 2005 by EKI identified the presence of organochlorine pesticides, primarily toxaphene, dieldrin and DDT, in shallow soil at Stock Corral #5 which is used for livestock management. The RI conducted in 2008 by Northgate further characterized the distribution and character of the organochlorine pesticides in the corral.

Results confirmed that toxaphene, dieldrin, and DDT, as well as several other pesticides, were present in shallow soil in Stock Corral #5. The occurrence of toxaphene and dieldrin in particular was widespread within the corral boundary (historical boundary, which is slightly larger than current boundary), though concentrations generally were higher and extended deeper in the eastern portion of the corral, where historical cattle spraying activities had occurred. Pesticide concentrations diminished with depth, and over most of the corral, were not detected at 2.5 feet bgs. At three locations in the eastern end of the corral, pesticides persisted to depths of 4.5 feet bgs.

The shallow depth of contamination and absence of shallow groundwater or surface water features in the vicinity of this corral limits the adverse impact the residual pesticides could have on the environment. The HRA concluded that residual pesticides remaining at Stock Corral #5 would not pose a health risk to future users of the property. Toxaphene concentrations in soil averaged approximately 0.42 mg/kg with a maximum concentration of 2.4 mg/kg, well below the SSTL of 4.2 mg/kg developed for a recreational use scenario. Dieldrin concentrations averaged approximately 0.0049 mg/kg with a maximum concentration of 0.038 mg/kg, also well below the SSTL of 0.38 mg/kg developed for a recreational use scenario. Other constituents, including DDT compounds, were below RWQCB ESLs for residential land use.

1.3.5 Fuel AST Area

The investigation conducted in 2005 by EKI identified the presence of TPH-D and TPH-G in shallow soil in the vicinity of two former ASTs that had been used to store small quantities of gasoline and diesel near a maintenance shed at the Lower Ranch. The RI conducted in 2008 by



Northgate further characterized the distribution and character of the petroleum hydrocarbons in the vicinity of the former ASTs.

Results of the RI indicated that very little TPH-D and TPH-G remain in the soil, and the only volatile constituents present are methyl-tert-butyl ether (MTBE) and 1,3,5-Trimethylbenzene (TMB), which were detected at low concentrations and at a low frequency. The low concentrations of residual TPH-D, TPH-G and the fuel additives in the soil suggest that the contamination has little potential to threaten the environment or to be a nuisance to future users of the property.

Shallow groundwater was present at a depth of approximately 28.5 feet bgs. Impact to groundwater from the fuel ASTs was limited, with only low concentrations of MTBE detected in the groundwater. The MTBE concentrations are below the RWQCB ESL for protection of groundwater that is not a current or potential source of drinking water (1,800 µg/L) but above the California State Maximum Contaminant Level (MCL) of 13 µg/L. The shallow groundwater in this area is not being used for domestic water supply and the localized occurrence of the MTBE is unlikely to pose a threat to groundwater resources.

The HRA concluded that residual TPH-D and TPH-G remaining at the Fuel AST Area would not pose a health risk to future users of the property. TPH-D concentrations in soil averaged approximately 33.25 mg/kg with a maximum concentration of 138 mg/kg detected, well below the SSTL of 19,000 mg/kg developed for a recreational use scenario. TPH-G concentrations averaged approximately 10.5 mg/kg with a maximum concentration of 160 mg/kg, also well below the SSTL of 19,000 mg/kg developed for a recreational use scenario. MTBE and 1,3,5-TMB concentrations were below residential RWQCB ESLs or EPA preliminary remediation goals (PRGs). Naturally occurring degradation processes likely will continue to reduce petroleum hydrocarbon concentrations in the soil over time.



2.0 SOIL MANAGEMENT

All on-site activities that will disturb the soil must be performed in accordance with this SMP and the approved site Environmental Health and Safety Plan (Appendix B). Requirements of the SMP are presented in the following sections. Employees of the District, The District’s tenants and lessees, and companies or individuals contracting with the District, its tenants or lessees, to conduct maintenance, construction, or repair work that would result in the disturbance of contaminated soil will be bound by the specific requirements set forth in this SMP, as appropriate.

These management procedures will be implemented during future construction activities that occur within the five identified areas, to control potential impacts to human health and/or the environment, and to alleviate possible aesthetic and nuisance conditions, if encountered.

Construction activities that are subject to the SMP include excavating, grading, removal, trenching, filling, earth movement, or mining. Minor disturbances with immediate replacement in kind (e.g., simple landscape maintenance such as fence installation, sprinkler-head repair, planting or re-planting, or similar activities that constitute a limited disturbance and immediate replacement in-kind of small amounts of soil) are not subject to the SMP. Soil that is not disturbed by construction activities or that is located outside of the five identified areas is not subject to the SMP, unless the soil exhibits conditions indicative of contamination.

2.1 Notification

Notification to the RWQCB will only be necessary if activities that disturb soil in the five identified areas (e.g., excavating, grading, removal, trenching, filling, earth movement, or mining) are not conducted in accordance with this SMP, or if an unknown area or condition of contamination is encountered. The District shall provide the RWQCB with written notice at least 10 working days prior to such planned activities, or within 15 working days of the discovery of any unplanned disturbance that did not meet SMP requirements. A sample notification form letter is included in Appendix C.

Other notification requirements pertaining to revising or modifying this SMP are discussed in Section 8.0.



2.2 Site Access Control

The potential for trespassers or visitors to gain access to construction areas and come into direct contact with potentially contaminated soil will be controlled by implementing access and perimeter security measures.

The responsibility for compliance with Site access control measures rests with the District and its contractors, if so designated by the District.

2.3 Soil Excavation

General public access shall be restricted during any activity on the Site that disturbs contaminated soil. Any soil that is brought to the surface shall be placed on plastic sheeting or other suitable containment measure (e.g., debris bin or drum). Any soil brought to the surface shall be wetted or covered to control the generation of dust. Stockpiled soil will be covered with plastic at the end of each day. Public access to the soil must be restricted at all times.

To the extent practical, any excavated soil should be used to backfill the excavation from which it was derived. Any soil that cannot be used to backfill the excavation must either be used as fill in another area approved by the RWQCB or removed from the Site.

2.4 Soil Removal

Any soil removed from the Site must be handled in accordance with existing laws and regulations. Based on the concentrations of pesticides and TPH in the soil in the five identified areas, the soil may need to be removed to a regulated landfill. A sample notification letter for removing soil from the Site is included in Appendix C.

Specific chemical testing should be performed on any soil that is to be removed from the Site. At a minimum, this testing should include analysis for:

• Organochlorine pesticides using EPA Method 8081 (from former corral #5 area);

• TPH-O using EPA Method 8015M (with silica-gel cleanup) (from the three oil field areas);

• PAHs using EPA Method 8270-SIM or 8310 (from the three oil field areas);

• TPH-D and TPH-G using EPA Method 8015M (with silica-gel cleanup) (from the former tank area); and,

• Benzene, toluene, ethylbenzene, xylenes (BTEX) and methyl-tert-butyl ether (MTBE) using EPA Method 8021B (from the former fuel AST area).



Additional chemical testing may be required based on the proposed destination of the excavated soil. Appropriate disposition of the soil will be based on comparison of the chemical test results with applicable standards or guidance, such as the following:

• U.S. EPA Preliminary Remediation Goals

• Title 22 of the California Code of Regulations (CCR)

• Acceptance criteria for permitted land disposal facilities

• Other recognized standards, as appropriate.



3.0 DISMANTLING OF REMAINING OIL FIELD INFRASTRUCTURE

Oil field closure activities are documented in a Final Closure Report, La Honda Main Oil Field, dated February 1, 1995 (Castleman, McFalone & O’Blennis [CMO], 1995). The San Mateo County Health Services Agency (SMCHSA) approved closure activities in 1995 and issued a closure letter on March 1, 1995 (SMCHSA, 1995). During closure activities, most of the oil field infrastructure was removed or abandoned in place.

Some remnant structures related to the area’s former use as an oil field, however, were encountered during the RI. A few disconnected sections of empty metal piping were found at various locations, and an apparent abandoned well was also encountered in the vicinity of the former Tank Farm. The RI contains a specific description of the location of this abandoned well.

To prevent a nuisance condition on the property, dismantling of the remaining infrastructure in the oil field areas should be completed. Because the specific locations of buried piping is difficult to assess and there are few available records indicating probable locations, District and Ranch maintenance and construction workers should be advised of the potential presence of buried piping and/or abandoned well heads in the former oil field areas. If encountered, the workers should report the information to the District. The District shall arrange for the removal and disposal or recycling, or appropriate in-place abandonment, of the infrastructure by a qualified contractor licensed to handle petroleum-containing materials. Care should be taken to inspect the infrastructure for the presence of residual petroleum hydrocarbons, and remove and dispose of any liquid content according to existing laws and regulations.



4.0 DUST CONTROL

Appropriate dust control measures will be implemented during any excavation or disturbance of soil in the five identified areas. In general, dust control will consist of keeping any excavated soil wetted or covered. As described in Section 2.2, excavated soil will be placed and covered with plastic sheeting, or otherwise contained. Water from trucks, hoses, or sprinklers shall be used, as necessary, during all excavation activities to control dust generation. All visibly dry disturbed soil surface areas shall be watered to control dust emissions, as necessary.



5.0 EQUIPMENT DECONTAMINATION/CLEANING

Equipment will be cleaned prior to movement out of active work zones. Cleaning may include, but not be limited to, dry brushing or scraping to remove loose soil or mud. Paved roads and other surfaces will be cleaned if the amount of dirt tracked in the operation area has the potential to cause dust emissions. Vehicles entering or exiting the construction area will travel at a speed that minimizes dust emissions. If washing with water is used to decontaminate equipment, the rinse water must then be contained and tested prior to discharge or disposal.



6.0 HEALTH AND SAFETY

Any excavation, trenching or roadwork activity that disturbs the soil in the five identified areas will be performed in accordance with the approved Environmental Health and Safety Plan (Appendix B).

The Environmental Health and Safety Plan has identified inhalation of dust and ingestion of soil as the primary chemical hazards at the Site. To minimize potential exposures, dust control measures will be implemented during all excavation activities. In addition, workers will be required to wear gloves when directly handling impacted soil materials. The reader should refer to the Health and Safety Plan (Appendix B) for specific recommendations.



7.0 RECORDKEEPING

The District shall keep records of all activities that disturb soil in the five identified areas regardless of whether specific notification to the RWQCB is required. Records shall be kept for all activities associated with the removal of remaining oil field infrastructure. Records, which shall be kept for a period of 10 years from the date of disturbance, should include the following information:

• The date of the activity

• A description of the general nature of the activity

• The name of the entity performing the activity

• Site or dust control measures implemented

• Test results of any chemical testing performed

• The disposition of any soil or other materials removed from the property

These records will be available for review at the District’s offices by the RWQCB. A sample recordkeeping form is included in Appendix C.



8.0 REGULATORY OVERSIGHT OF SMP

This section describes the regulatory oversight mechanisms to assure that the SMP remains in place and continues to be effective. Each Owner/Lessee of the Driscoll Ranch Property will be notified of the SMP and its contents, and will be required to comply with it.

8.1 Process for Modifying the SMP

In the event that the provisions of the SMP need to be modified, the District will present a proposed modification to the RWQCB for its approval. The RWQCB will review the proposed modification, request any additional background information, if needed, and issue a decision regarding the proposal within 30 days following receipt of a completed application. Once the RWQCB has approved the SMP modification, the revised pages will be filed in the RWQCB public copy of the SMP.

Conditions that may warrant modification to the SMP include (but are not limited to) changes to the future use or ownership of the property, plans to construct buildings in the contaminated areas, or the development of other conditions that are inconsistent with current plans to use the property as an ecological preserve and cattle ranch.

A page will be added to the front of each copy of the SMP when modifications are inserted, indicating the dates and pages that have been updated/revised.

8.2 Incorporating the SMP in All Future Leases, Licenses, or Other Agreements

An Owner or Lessee will incorporate the SMP in all future leases, licenses, permits, or other agreements (“agreement”) that authorize another entity to engage in an activity that is subject to one or more of the requirements in this SMP. Prior to execution of the agreement, the Owner or Lessee will provide a copy of the SMP or its relevant provisions to such entity. The Owner or Lessee will also ensure that the agreement contains provisions that such entity will: (1) comply with the SMP (to the extent the SMP is applicable to such party’s activities; (2) obligate other entities with which it contracts for construction, property maintenance, or other activities which may disturb the existing soil to comply with the applicable provision of the SMP; and (3) refrain from interfering with the Owner’s or Lessee’s compliance with the SMP.

Preserve site, La Honda, San Mateo County Dear Mr. Lenington: We have reviewed the December 19, 2008 Remedial Investigation (RI) report for the Driscoll Ranch – La Honda Creek Open Space Preserve site, prepared on behalf of the Midpeninsula Regional Open Space District (the District) by Northgate Environmental Management, Inc. (Northgate). The RI report was subsequently amended for further clarifications, per discussion in the January 13, 2009 meeting between the District and the Water Board staff. The amended RI report was submitted electronically on January 23, 2009, and is hereby approved. We concur with Northgate’s conclusions that no further environmental investigation is necessary at the main oil field area, tank farm area, product tank area, stock corrals, or fuel aboveground storage tank area. We also concur with Northgate’s conclusion that currently-known site conditions are protective of human health and the environment under the projected future use scenario of an ecological preserve and continued cattle ranching. Therefore, no remedial measures for soil or groundwater, other than naturally occurring biodegradation, will be necessary. Northgate recommended, however, that the following follow-up tasks be performed by the fall of 2009 so as to prepare the Site for public access, which is targeted for the summer of 2010:

(1) Dismantling of remaining infrastructure at the tank farm area. (2) Proper abandonment of the inactive water supply well in the vicinity of the tank farm

area. (3) Collect confirmation sampling at the refuse disposal area after removal of the refuse for

off-site disposal. (4) Prepare a Soil Management Plan to document current soil conditions and provide

guidance on soil handling, disposal, or reuse procedures, including health and safety provisions for workers that might encounter the contaminated soils.

EXECUTIVE SUMMARY This Environmental Health and Safety Plan (EHASP) provides guidelines for the safe handling of surface and subsurface soils that may contain residual petroleum hydrocarbons (crude oil and gasoline) and pesticides (primarily toxaphene and dieldrin) in the event that the soils are excavated during construction activities. The potential for occupationally significant airborne exposure to these contaminants is very low, particularly with diligent attention to dust control (see Section 3.2 of EHASP) during construction activities. The potential for skin absorption is also low because the contaminants in question have poor dermal absorption characteristics. The incidental ingestion of these contaminants can also be avoided by following good personal hygiene practices (See Section 8.1). Because the overall potential hazard to site contaminants is very low, compliance with Hazardous Waste Operations and Emergency response (HAZWOPER) regulations is not required. Nonetheless, it is appropriate to engage in prudent work practices as detailed in this EHASP. This information should be reviewed before beginning excavation work associated with soils that may be contaminated. Furthermore, it is important not to overlook the health and safety hazards associated with construction work and to adhere to the requirements of applicable Cal-OSHA regulations and any injury and illness prevention plan (IIPP) that may be in effect when work begins.


Environmental Health and Safety Plan Driscoll Ranch Property December 2009 La Honda, San Mateo County, California

3

1.0 Introduction The purpose of this Environmental Health and Safety Plan (EHASP) is to provide health and safety guidelines for operations and maintenance work at the Driscoll Ranch Property site located at 5460 La Honda Road in La Honda, San Mateo County, California. Previous investigations found low to moderate levels of residual petroleum hydrocarbons (crude oil and gasoline) and pesticides (primarily toxaphene and dieldrin). The primary activities that will trigger adherence to this EHASP are excavation, trenching, roadwork or other earthwork that causes significant disturbance of soil in the soil management areas described in the Soil Management Plan (SMP) prepared by Northgate (Northgate, 2009). Previous environmental assessments (Erler and Kalinowski, Inc. [EKI], 2001 and 2005) identified hazards relating to portions of the site that were formerly used as an oil field and for cattle ranching operations. Soil containing residual petroleum hydrocarbons (primarily as crude oil) and pesticides (primarily toxaphene and dieldrin) were found during site investigations. Residual gasoline and diesel fuel were also found in soils associated with small above-ground storage tanks (ASTs) formerly used by Driscoll Ranch. More recent investigation by Northgate (Northgate, 2008), delineated the nature and extent of the contaminants, and assessed the potential health risks associated with the contaminants by performing a human health risk assessment (HRA). The HRA concluded that pesticide compounds and total petroleum hydrocarbons (TPH) are present in soil at levels for which recreational users, Ranch workers, and District staff may contact the soil without posing a health risk. However, maintenance and construction activities that cause disturbance to the impacted soil must be performed in accordance with the SMP and this EHASP, as required by the Regional Water Quality Control Board. Minor disturbances with immediate replacement in kind (e.g., simple maintenance such as fence installation, sprinkler-head repair, planting or re-planting, or similar activities that constitute a limited disturbance and immediate replacement in-kind of small amounts of soil are not subject to this EHASP. Soil that is not disturbed by construction activities or that is located outside of the five identified areas is not subject to this EHASP, unless the soil exhibits conditions indicative of contamination. This EHASP is directed toward workers who perform maintenance and construction activities and whose work will require them to handle contaminated soils. Provisions of the EHASP also apply to other personnel on site who may have occasion to enter contaminated work areas. This EHASP shall be available on site during all activities that require handling of contaminated soils. This EHASP includes the overall general responsibilities of general contractors and all subcontractors, to meet minimum prescribed safety provisions in handling contaminated soils or materials. This EHASP is not intended to either replace work practices or substitute existing safe work practices as described in the general contractor’s or other subcontractor’s Illness and Injury Prevention Programs as required in 8CCR3203. These IIPPs are incorporated into this document by reference. The following document was reviewed for this EHASP:

• Northgate Environmental Management, Inc. “Soil Management Plan, Driscoll Ranch Property, La Honda, San Mateo County, California” December, 2009.

1.1 Overview of Work The work covered by this EHASP consists of soils work necessary for as needed maintenance or construction that require the disturbance of soils. Examples of such work include trenching for the installation or removal of underground utilities, construction that requires excavation of soil, roadwork that requires earthwork, etc. Existing site conditions as reported in the SMP indicated the presence of low to moderate levels of a number of contaminants (hydrocarbons and pesticides) in shallow soils at the site. These materials may be present at the ground surface or below the ground surface to depths up to



4

approximately 5 feet below grade in the case of pesticides, or up to approximately 40 feet below grade in the case of petroleum hydrocarbons. Known site contaminants are further discussed in Section 3.2.

1.2 Site History According to the project documentation, Driscoll Ranch includes more than 3,682 acres of land owned by Midpeninsula Regional Open Space District (the District). The District plans to incorporate Driscoll Ranch into the La Honda Creek Open Space Preserve. The primary objective of the Preserve is ecological habitat preservation. There will be limited recreational access to the Preserve via hiking, equestrian and potentially biking trails. The District also plans to have a residence for District personnel. Additionally, continued cattle grazing, special events parking associated with the existing Driscoll Ranch Event Center, up to three residences, and limited equestrian and pedestrian use of the property by the tenant, Mr. Rudy Driscoll, is allowed under a Lease-Agreement. It is the District’s intent to manage residual contamination remaining on Driscoll Ranch while also allowing safe public access to the property.

2.0 Project Organization

2.1 Project Manager/Superintendent The Project Manager/ Superintendent, who shall be appointed prior to the start of a construction activity that involves soil excavation, has responsibility for overall management of health and safety for the project. Specific duties include:

5

• Ensure personnel wear the appropriate protective equipment in the work areas (Section 5.0)

• Control access into contaminated areas and ensure that only trained and authorized personnel enter these areas

• Ensure that site personnel receive necessary training (Section 6.0)

• Ensure air monitoring is conducted (Section 7.0)

• Ensure District employees and relevant subcontractors comply with the medical surveillance requirements (Section 14.0)

• Conduct periodic inspections of the work area health and safety conditions

• Assist the project manager with his/her health and safety related responsibilities

• Stop work if there is any reason to expect that the work cannot be completed safely

3.0 Hazard Analysis

3.1 Routes of Exposure In dealing with any hazardous or potentially hazardous substance, all routes of exposure should be protected as necessary. These routes and methods to minimize exposure are described below.

3.1.1 Inhalation

Inhalation is the most common route of occupational exposure to gases, vapors, mists, fumes or dusts. It may result in respiratory damage and/or may cause systemic illness. The risk of such adverse effects depends on the airborne concentration and on the nature of the contaminant(s). The CA Division of Occupational Safety and Health (Cal-OSHA) has promulgated Permissible Exposure Levels (PELs) for airborne contaminants. PELs represent legally enforceable limits for airborne exposure to contaminants. Exposures that exceed current PELs require protective measures such as engineering and or administrative controls and or the use of respiratory protection. Cal-OSHA’s PELs may be found in Title 8 of CA Code of Regulations Section 5155 (8CCR5155).

Sections 5.0 and 13.0 discuss the selection of respiratory protection for this project. Section 7.0 describes when respirator use may be discontinued.

3.1.2 Skin Contact

Skin contact with certain materials may cause skin irritation and may also result in systemic absorption. The following precautions must be used when inspecting sites which may contain materials with the potential for dermal absorption:

1. Ensure that exposed skin is protected during site work;

2. Use proper procedures for removing contaminated clothing while still at the site;

3. Contaminated rags and other disposable items, such as gloves, should be bagged for proper disposal, avoiding skin contact;

4. Choose protective clothing suitable for anticipated materials; and

5. If skin contact with hazardous materials occurs, immediately rinse area with water and seek medical attention.

Section 5.2 discusses the appropriate personal protective equipment suitable for this project. As discussed in Section 3.2, dermal hazards associated with site contaminants are low.



6

3.1.3 Ingestion

The ingestion of hazardous material may occur when drinking, eating, or smoking in contaminated areas, or with contaminated hands. This can be avoided through the use of the prescribed protective clothing, through the restriction of eating, drinking, and smoking to uncontaminated areas, and through good personal hygiene practices. Eating, drinking and smoking are prohibited on-site until personal hygiene practices have been followed. The decontamination procedures described in Section 8.0 are intended to minimize the potential for accidental ingestion of toxic materials.

3.1.4 Eye Contact

The eyes are sensitive to damage from a number of solids, liquids, or vapors. Effects may range from mild irritation to severe damage. The actual effect depends on the material and on the quantity to which the eye may have been exposed. The following precautions to avoid eye injury must be taken when entering the site:

1. Wear safety glasses with side shields or goggles;

2. Do not rub eyes;

3. Never wear contact lenses when working in areas where hazardous materials may be encountered. Contact lenses cannot be worn when respirator use may be required; and

4. If eye contact with hazardous materials occurs, immediately rinse eyes with water and seek medical attention.

3.2 Chemical Hazards The chemical hazards associated with this project are anticipated to be low. Residual site contaminants consist of low levels of hydrocarbons (gasoline, diesel, crude oil) semi-volatiles (polycyclic aromatic hydrocarbons) and pesticides (mainly toxaphene). Table 1 to Table 3 shows the maximum levels of compounds detected in soil during previous investigations at the site and provides an industrial hygiene evaluation of anticipated exposures while disturbing contaminated soil. Potential inhalation exposures to airborne organically bound chemicals are expected to be low. Airborne dust generally becomes visible at level concentrations of approximately 0.5 milligrams of dust per cubic meter of air (0.5 mg/m3). This level of dust represents 5% of the current Cal-OSHA Permissible Exposure Limit (PEL) for total dust. If just visible airborne dust were to contain the highest reported level of toxaphene in areas to be potentially disturbed, this concentration of dust would represent 0.001 milligrams of toxaphene per cubic meter of air (mg/m3). This is equivalent to 0.002% of the current Cal-OSHA Permissible Exposure Levels (PELs found in 8CCR5155 Table AC1). Note that the Cal-OSHA AL is based on an 8 hour time weighted average (8h-TWA). Therefore, to reach worst case projected exposures would require continuous emissions of just visible dust for an entire shift. Given that dust control is a project requirement, this is an unlikely scenario. Consequently, the airborne toxaphene exposure hazard is expected to be extremely low for construction and maintenance activities that may be performed at the property. Dermal exposure is not a concern because toxaphene is not absorbed through the skin. However, inadequate personal hygiene practices could lead to inadvertent ingestion of residues. Dermal exposure and incidental ingestion of hydrocarbons on site are not expected to be a significant with good hygiene practice. Use of excavation equipment may generate airborne dust, which may be inhaled. Note that site work practices will require dust control measures so as to minimize visible dust emissions. Therefore the dust inhalation hazard is also expected to be low.



7

In summary, the contaminants identified on site are at too low a concentration to present a significant exposure hazard under anticipated working conditions. Dust control and personal hygiene practices will serve to minimize exposure to known site contaminants.

3.3 Physical Hazards The physical hazards of this project should be normal to maintenance and construction work and thus should already be addressed in contractor’s IIPPs. These are incorporated by reference into this EHASP and shall be available on site during field work. However, the following safety issues should be considered if trenching or excavation work is conducted..

• Underground utility clearance before excavation.

• Compliance with Cal-OSHA’s excavation safety orders if the work will require anyone to enter excavations deeper than five feet. These orders require a permit from Cal-OSHA as described in 8CCR1539.

• Entry into trenches and excavations shall be considered confined space entry and shall conform to the requirements of 8CCR5158.

Other physical hazards typical of construction activities include working around heavy equipment, electrical work, noise, slips and falls, back strains from lifting, and cuts from jagged edges and protrusions. These hazards are already addressed in the contractor’s IIPP, and should be discussed during routine tailgate safety meetings. Work with and around heavy equipment will require adherence to the following general practices. The safe practices stated below are not intended to substitute existing IIPP requirements. They are reiterated below to serve as reminders for site employees:

• Use of reflective vests around moving equipment.

• Eye contact with equipment operator.

• Operators to be trained on the proper use and limitations of the equipment.

• Rated equipment capacity shall not be exceeded.

• Operators shall wear seat belts provided.

• All equipment to be inspected each day before use.

• Equipment guards shall be left in place except for routine maintenance and for repairs. Guards removed shall be replaced promptly.

• Manufacturer’s recommended preventive maintenance procedures shall be followed.

• Personnel shall not work under suspended loads.

• Equipment shall be fitted with audible electronic back up alarms.

• Equipment shall be placed on firm stable ground before use.

• Operators and employees shall use seats provided only.

• Operators shall not get on or off equipment while it is in motion. Work around equipment or noise sources that exceed 85 decibels on the A-weighted scale will require the use of either ear muffs or insert hearing protectors. Ear muffs shall be maintained in a clean and sanitary condition. Insert hearing protectors shall be disposed of after each use. Users of insert protectors shall ensure hands are clean before inserting plugs into ears.



8

3.4 Overview of Safety Procedures The hazards described above shall be controlled through a combination of engineering and administrative controls and through the use of personal protective equipment. The engineering controls applicable to this project shall be to implement appropriate dust control measures to minimize visible airborne dust emissions. This shall consist of a water truck to be used continuously on contaminated soil that is excavated so as to minimize dust emissions. If visible dust clouds are noticed at any time during construction activities, the dust-producing work in that area will be required to be discontinued until dust control measures are effective at controlling visible dust emissions. The administrative controls for this project shall consist of limiting access to contaminated areas to properly trained and equipped personnel. These individuals shall follow the required decontamination procedures when leaving the contaminated work areas. In addition, smoking and other sources of ignition will be prohibited from trench areas until they have been evaluated for methane accumulation. The project Health and Safety Officer shall ensure the following activities are conducted so that employees are properly protected when the work involves handling contaminated materials:

• Designate contaminated areas and establish site control;

• Provide the necessary equipment for decontamination;

• Conduct daily site inspections to verify the appropriate precautions are in effect;

• Conduct periodic air monitoring of excavations;

• Identify the nearest emergency facilities (if not already done); These procedures are described in this EHASP.

4.0 Site Control

4.1 Contaminated Areas Known site contaminants are present in low concentrations in most areas, with occasional pockets of higher concentrations. As explained in Section 3.2, it is unlikely that worker exposure will exceed applicable Cal-OSHA PELs. Therefore, exclusion zones as defined in 8CCR5192 will not be required. However, areas either known to be contaminated or areas where there is visible evidence of contamination (soil discoloration, odors etc.) shall be designated as contaminated areas. These shall be delineated with cones, barricade tape, temporary or other visible means. Appropriate personal protective equipment shall be worn when working in this area as described below. The absence of exclusion zones shall not relieve site workers from the requirement for personal hygiene before eating, drinking or smoking. Vehicle access into contaminated work areas shall be restricted only to the equipment required for the work, and to the water truck for dust control. Access to construction zones where contaminated soil is being excavated shall be restricted to authorized personnel only. Site visitors will be required to check in with District staff upon entry and exit. Visitors authorized to enter active work areas shall sign in an entry and exit log. Access to the site shall be locked outside working hours.



9

4.2 Decontamination Area Hand washing facilities shall be provided on-site, whenever soil disturbing activities occur. The station shall be stocked with soap, water and towels. The facilities shall be sufficient for the number of employees on-site.

5.0 Personal Protective Equipment

5.1 Selection Criteria The EPA has classified personal protective equipment (PPE) ensembles into four categories for different levels of hazards. They are as follows.

• Level A This type of protection should be worn when the highest level of respiratory, skin, eye and mucous membrane protection is needed.

• Level B Level B protection should be selected when the highest level of respiratory protection is needed, but a lesser level of skin and eye protection.

• Level C This level protection should be selected when the actual or potential airborne substance(s) is known, the concentration(s) is measured, the criteria for using air-purifying respirators are met, and skin and eye exposure is unlikely. Periodic air monitoring is necessary.

• Level D Level D is primarily work clothing. The PPE selection criteria for unexpected toxic hazards that may be encountered are based on two major parameters:

• Type(s) and measured concentration(s) of the chemical substance(s) in the atmosphere, with its (their) associated toxicity.

• Potential for exposure to high air concentrations of volatile substances, splashes of liquids, or other types of direct contact with material due to work functions being performed.

PPE for activities where the identity of contaminants is available requires consideration of the following:

• Identity of either known or suspected contaminant.

• Actual or potential airborne concentration.

• Skin toxicity data.

• Potential for skin or eye contact.

5.2 Contaminated Area PPE Requirements As stated in Section 3.2 of this EHASP anticipated exposures by all occupationally relevant routes is not expected to be significant. Therefore, the following (EPA level D) personal protective equipment shall be worn in contaminated areas:

• Hardhat (if working around heavy equipment);

• Work boots; and

• Safety glasses with side shields. All personnel who may come into direct skin contact with contaminated materials shall wear the above described PPE clothing, in addition to the following as necessary to prevent contact with the site materials:



10

• Nitrile gloves (when handling contaminated soils and equipment);

• Tyvek or equivalent disposable coveralls; and

• Chemical splash goggles (to prevent splash into the eyes). Unnecessary contact with potentially contaminated residues shall be avoided as much as possible. Should air monitoring results (as discussed in Section 7.0 of this EHASP) warrant the use of respirators, protective equipment shall be upgraded to Level C.

5.3 Clean Area PPE Requirements Work outside contaminated areas shall require the use of EPA level D protective equipment normal to the construction industry. Typically, this consists of hard hats, safety footwear, normal work clothing, and safety glasses as necessary.

6.0 Employee Training As discussed in Section 3.0 of this EHASP, it is unlikely that site activities will result in exposure to health hazards other than those associated with construction activities. Site personnel shall be familiar with the contents and requirements of this EHASP. This information shall be presented at a project start-up tailgate safety meeting mandatory for all site personnel engaged in construction activities that require soil excavation. The Health and Safety Officer will conduct this meeting. Table 4 shows an outline for the site specific tailgate safety meeting in this EHASP which shall include a brief discussion on the hazards of pesticide and petroleum hydrocarbon exposure. Additionally, employees required to enter trenches shall receive confined space awareness training that will include a discussion of emergency procedures. This training shall be consistent with a confined space entry program. During field work, tail-gate meetings will be held at the start of each work week to discuss the planned activities and any health and safety-related issues. Additional meetings may be needed after events such as procedure changes, PPE level adjustments, accidents, or additions to this EHASP. These meetings will be arranged by the Health and Safety Officer. All subcontractor personnel who may disturb contaminated soil will be required to complete the same level of training as described above, and shall attend all safety briefings. Employee attendance shall also be documented in training attendance records (sign-in sheets). This training is additional to the training required under the District’s IIPP. Additional training may be required should project conditions change or warrant it. This includes respiratory protection training if air monitoring shows respirators are needed. Prior to commencing work each day, either the Health and Safety Officer or Project Manager will ensure that the following tasks are performed:

1. Safety briefing, as scheduled, for all site personnel to discuss the activities to be performed during the day, as well as any anticipated safety or health issues. A weekly safety briefing will also emphasize proper emergency procedures, and will identify any health and safety related changes from this EHASP.



11

2. A site inspection to identify and eliminate or control physical hazards that may exist on the project site (moving ground, tripping hazards, slipping hazards, sharp objects, etc.).

3. Proper delineation of contaminated work areas with barricades or barrier tape as needed.

4. Scheduling of personnel so that only the personnel necessary to complete the day’s work are allowed to work in contaminated work areas.

7.0 Worker Air Monitoring As discussed in Section 3.2, airborne exposures to petroleum hydrocarbons are not expected to exceed the current Cal-OSHA Permissible Exposure Levels (PELs), with dust control. However, this shall be verified through monitoring whenever workers detect hydrocarbon odors. Hydrocarbon monitoring shall consist of periodic breathing zone monitoring with a photoionization detector (minimum 10.2 eV source). Personal protective equipment shall be upgraded from modified Level D to modified Level C (same as modified Level D but with respirators required) whenever breathing zone readings show more than 5 parts per million (ppm) for five consecutive minutes. Section 5.2 of this EHASP provides additional details on protective clothing ensembles. Respiratory protection use may be discontinued if breathing zone readings fall below this criterion. An alternative response to respirator use shall be to suspend operations until air concentrations fall below 5 ppm for 5 consecutive minutes. Monitoring for combustible gases, including methane, and oxygen levels will be conducted for all trenches into which personnel will enter, prior to their entry. This monitoring will be conducted utilizing a calibrated combustible gas/oxygen meter. If combustible gas readings in excess of 10% LEL are encountered, personnel will not enter the trench until readings are consistently below 10% LEL. In addition, if LEL readings are encountered, soil conditions will be evaluated for the presence of unknown contaminants, and the appropriate actions taken if either soil staining or odors are noticed. Because it is unlikely that these criteria would be exceeded during this project as explained in Section 3.2 of this EHASP, and as will be corroborated by air monitoring conducted during earth disturbing activities, personal air monitoring is not required for the work covered by this EHASP. This does not however relieve contractors who may disturb contaminated soil from minimizing dust emissions.

8.0 Decontamination . Personnel working with soils onsite areas shall wash their hands and face before eating, drinking or smoking. This decontamination area shall consist of:

• Temporary disposal containers for disposable protective equipment, consisting of trash cans or drums with liners. When full, the liners are to be removed, secured, and placed with the other contaminated materials for proper disposal.

• Hand and face washing facilities, which provide running water, soap, and paper towels. Employees should wash their hands thoroughly with soap and rinse with copious amounts of water prior to drying. . If running water is not available, then water-less cleansers or wipes may be used.

The sequence for employees to use when decontaminating follows:

1. Remove protective equipment.

2. Wash hands and face with soap and water, or alternative.



12

Boots and gloves may be reused provided contaminated residues have been removed. Otherwise they shall be replaced as necessary. Respirators are not required. If unknown contaminated materials are encountered on site, decontamination procedures will be adjusted so as to prevent the spread of contaminated materials outside of the work site.

8.1 Equipment Decontamination At the end of each day tools and other small equipment will be cleaned in the same manner as personal protective equipment. Contaminated heavy equipment shall be decontaminated by cleaning off visible residues and placing them either back into the excavations or onto spoils piles. Visibly clean equipment shall be considered decontaminated. Contaminated equipment shall not be removed from the regulated area until it has been cleaned. Footwear, tools and equipment shall be cleaned of mud, dirt and other debris at the end of each day or before removal from potentially contaminated work sites. Debris and other wastes shall be placed back to their site of origin. Rinsate and water shall be collected and handled in the same manner as other water collected on site. This may include reuse as dust control on site, or discharge to the ground surface in a manner that does not produce runoff. Disposal of all liquids will be performed only after obtaining the appropriate permission.

9.0 Emergency Response Table 5 contains emergency response telephone numbers to be used in emergencies. Normal on site communications shall consist of two way radios and cell phones.

9.1 Employee Injury or Illness The affected employee shall be removed (if it can be done safely and without aggravating conditions) and transported to Sequoia Hospital. Emergency telephone numbers are listed on Table 5. Only individuals currently trained in first aid or CPR shall render this type of assistance. Table 6 contains directions to the emergency facility.

9.2 Emergency Equipment Emergency equipment available on-site shall consist of:

• First aid kits (to be used by trained personnel only).

• Fire extinguishers (10 A,B,C ratings). Fire extinguishers shall be available at the jobsite trailer, and in each supervisor vehicle. Fire extinguishers shall be inspected annually, and during each job site inspection they are re-charged as necessary.

9.3 Emergency Decontamination As project related chemical hazards are expected to be low, it is unlikely that employee contamination can present a life threatening condition. Therefore, emergency employee decontamination shall consist of removing protective clothing and washing with soap and water as necessary. If necessary, protective clothing shall be cut away and removed before transportation to an emergency facility.



13

9.4 Emergency Evacuation In the unlikely event of site evacuation, an air horn will be used to sound the alarm. Reasons for emergency evacuation include trench collapse, fires and explosions. Employees shall report to the Project Superintendent’s vehicle without delay where the Superintendent shall conduct a head count.

9.5 Unusual Conditions Site employees shall be instructed to cease work, and immediately report to the supervisor should they encounter unusual conditions such as strange odors or liquids. The Superintendent shall assess conditions, and shall consult with Mr. Paul M. Spillane, CIH, as needed. If necessary, work shall be temporarily suspended until the situation can be properly addressed.

10.0 Spills Contaminated soils spills onto uncontaminated areas shall be handled by prompt response that will include restricting the immediate area to authorized personnel only. The soil shall then be picked up, removed, and placed either in an appropriate spoils pile or in the excavation. Personnel handling contaminated soil shall be current in the training specified in Section 6.0 of this EHASP.

11.0 General Safe Work Practices The project operations shall be conducted with the following minimum safety requirements employed:

• Personnel on-site are to be thoroughly briefed on the anticipated hazards, equipment requirements, safety practices, emergency procedures and communication methods, initially and in daily briefings.

• Dust control measures to minimize airborne dust emissions.

• Eating, drinking, chewing gum or tobacco, smoking, or any practice that increases the probability of hand to mouth transfer and ingestion of materials is prohibited in all areas of soil work.

• Removal of materials from protective clothing or equipment by blowing, shaking, or any other means that may disperse materials into the air is prohibited.

• Personnel should be cautioned to inform each other and their supervisor of subjective symptoms of chemical exposure such as headache, dizziness, nausea, and irritation of the respiratory tract.

• Contact with contaminated soil shall be minimized.

• Legible and understandable precautionary labels shall be prominently affixed to containers of raw materials, intermediates, products, mixtures, scrap, waste, debris, and contaminated clothing.

• Open excavations shall be covered, as feasible, if rain is expected, to minimize the accumulation of storm water.

• Spoils piles shall be covered with polyethylene that shall be weighed down so as to prevent contaminated soil emissions from wind and rain.

• Wherever possible, spoils shall be placed back into the excavation after work is completed. Waste soils to be transported off site shall be characterized for appropriate waste disposal.

12.0 Sanitation The District and its subcontractors will provide the proper sanitary facilities for use by all personnel assigned to construction work involving excavation of contaminated soil. These shall include temporary



14

toilets that shall be serviced at least weekly, and self-contained washing facilities that shall include a clean water supply, soap dispenser, and disposable towels.

13.0 Respiratory Protection The District and its subcontractors shall provide employees with appropriate respirators if air monitoring as described in Section 7.0 indicates their use is necessary. Respirator use shall be consistent with the requirements of 8CCR 1529 (Cal-OSHA’s Respiratory Protection Standard for the construction industry). The District and its subcontractors shall provide respirators that are applicable and suitable for the purpose intended. The appropriate respiratory protection for this project if the criteria in Section 7.0 are exceeded is a half face respirator fitted with organic vapor filters and HEPA pre-filters. These respirators (NIOSH approved half face) have a rated protection factor of 10. As described in Section 13.0 of this EHASP, all employees required to wear respiratory protection shall be required to undergo annual medical evaluations. District and subcontractor respiratory protection policies shall not permit respirator use when conditions prevent a proper facepiece-to-face seal. Such conditions as facial hair, scars, wrinkles, facial diseases, denture removal, or other disorders could prevent a proper facepiece-to-face seal. Contact lenses may not be worn when using any respirator. District and subcontractor supervisors and employees shall be current in the respiratory protection training including the proper selection and use of respirators and their limitations. All training is documented with records retained in the employee’s training files. Anticipated airborne exposures to site contaminants are expected to be less than 1% of applicable PELS. Therefore, respiratory protection is not required when working with contaminated soils unless air monitoring as described in Section 7.0 indicates its use is necessary. If required for other tasks, the use of respiratory protection shall be consistent with 8CCR1529 (Cal-OSHA’s Respiratory Protection Standard for the construction industry). This includes the implementation of a written respiratory protection program, as well as documented medical evaluations, training and fit testing for all respirator users.

14.0 Medical Surveillance District and subcontractor personnel engaged in construction work that may involve work with unknown contaminated materials, shall participate in an annual medical surveillance program, and shall be cleared by the examining physician(s) to wear respiratory protection devices and protective clothing for work with hazardous materials as required by 8 CCR 5192 prior to field assignment. As stated in 8CCR5192(f)(3)(A)1 through 8CCR5192(f)(3)(A)5, the medical surveillance program shall include:

• Medical and work history with emphasis on symptoms related to hazardous substance handling and health hazards, and fitness for duty including the ability to wear the required personal protective equipment under conditions expected at the site.

• Medical examination, the content of which shall be determined by the examining physician. This may include pulmonary, liver and kidney function tests, as well as hematological and neurological tests.

These examinations shall be provided without either cost to employees or loss of pay to said employees, at a reasonable time and place. A licensed physician, preferably one knowledgeable in occupational medicine, shall be retained to provide the required medical examinations. In addition, medical examinations shall be



15

provided at least once every twelve months (unless the attending physician believes a longer interval (not greater than biennially) is appropriate). Medical examinations shall also be provided for employees who may have been injured, received a health impairment, or developed signs or symptoms which may have resulted from exposure to hazardous substances above applicable PELs without the necessary personal protective equipment. Such exams shall be provided as soon as possible after the incident, or the development of signs or symptoms, and at additional times as determined by the examining physician. Medical records associated with this program are maintained in a manner consistent with the requirements of 8CCR3204. This regulation stipulates that medical records be maintained confidentially for at least 30 years following the termination of a participant in this program. Medical surveillance is not initially required for this project because exposures to site contaminants are not expected to exceed Cal-OSHA PELs (or Action Limits) as explained in Section 3.1 of this EHASP. However, should conditions change such that exposures may be anticipated to exceed applicable PELs, site personnel engaged in project operations involving work with contaminated materials shall be cleared by the examining physician(s) to wear respiratory protection devices and protective clothing for working with hazardous materials as required under 8CCR1529 and 8CCR5192. Medical records associated with this program are maintained in a manner consistent with the requirements of 8CCR3204. This regulation stipulates that medical records be maintained confidentially for at least 30 years following the termination of a participant in this program.

15.0 Standard Operating Procedures Section 8.0 of this EHASP contains standard operating procedures (SOPs) for decontamination. Other SOPs relevant to site construction work are included in the District’s and subcontractors’ IIPPs which are incorporated into this EHASP by reference. They will be available on site for review during field work.

INTRODUCTION

Per the District’s request, on 12/5/12 I performed a visual inspection of the subject bridge. I was accompanied by District employees, Lisa Bankosh and Rich Hopp. My purpose was to determine the overall condition of the bridge, its abutments, and adjacent stream banks. If possible I would also estimate a load rating.

This bridge is 20.2-feet wide and thus is considered two-lanes. The bridge consists of side-by-side railroad flat cars. The analysis in this report is per single lane.

LOCATION

The bridge is located approximately 1.6 miles west of State Highway 84 in the La Honda Creek Open Space Preserve. See map in the appendix.

INSPECTION METHODS

Inspection was visual only – no sampling or laboratory testing was performed. We did not disassemble any portion of the bridge, thus were able to inspect only what was observable from various positions on, under, and around the structure. Our investigation took approximately 1.5 hours.

A pocket knife was used as a scraper in random locations to estimate extent of rust. A battery- powered, hand-held electric drill with 1/8” diameter x 6” long bit was used to test wood members for rot in random locations. No digging or excavating was performed to expose buried members. Distances and dimensions were determined using a hand-held tape measure.

No soil borings, lab work, or other detailed geotechnical investigation was made as part of the investigation. Thus we are only able to estimate the bearing capacity, slope stability, and erosion potential based on our visual inspection.

INSPECTION RESULTS

The results of our inspection are summarized in two tables in the appendix:

Table 1 indicates general information, materials, sizes, dimensions, etc.

Table 2 indicates the condition of the various bridge elements. We used a rating scale, 1-10, with 1 being the worst condition possible, i.e. a failure; and 10 being the best condition possible, i.e. new.

It should be reiterated that we did not, nor could not investigate every element, connection, part and piece of the bridge assembly. Our condition rating is a general overview based on what we were able to observe.

LOADS

This bridge is 20.2-feet wide and thus is considered two-lanes. The bridge consists of side-by-side railroad flat cars. The following loads and capacity analysis are per single lane.

Dead Load: Dead load consists of the bridge’s self weight, not including the abutments. Our analysis indicates an approximate dead load (DL) of ~422 lb per lineal foot per lane, and 16,671 lb total dead weight of bridge per lane, as shown in the following table.


3 of 12

Live Load: Live load consists of vehicles, pedestrians, horses, etc. The controlling live load for bridge analysis is a truck.

Truck Loading: Standard bridge design specifies truck loadings of several types. We checked both H loading (two axles – single truck only) and HS loading (three axles – truck and trailer).

No increases due to impact, acceleration, deceleration, or turning (centrifugal) were used in our analysis.

We did not analyze wind, flood, or seismic loads.

The standard AASHTO highway truck loads we used are as follows:

H20: 8,000 lb front axle + 32,000 lb rear axle, axles 14’ apart. Total truck load = 40,000 lb.

HS20: 8,00 lb front axle + 32,000 lb rear axle, spaced 14’ apart, towing a trailer with 32,000 lb axle, 30’ behind the rear truck axle. Total truck + trailer load = 40,000 + 32,000 = 72,000 lb.

The loads used in our analysis are indicated in the table below.

CAPACITY ANALYSIS

Span: The bridge’s load capacity is geometrically proportional to span. As the span increases, the stress in the girders increases geometrically. We could not accurately determine the girders’ span because the abutments are below grade and not easily accessible. Railroad car bridges are typically supported by an abutment approximately 4-feet from the end of the bridge, but not always. This bridge’s deck length is 39.5-feet; the girder span is likely less than that but will require additional investigation to confirm. For the purposes of our analysis we assumed 33-feet inside of abutment to inside of abutment span.

Girders Of Varying Stiffness: When load is shared among structural members with varying sizes, individual members take load in direct proportion to their stiffness. Stiffness is defined by a member’s moment of inertia, “I”, and its modulus of elasticity, “E”. In the case of this bridge, “E” (steel’s modulus of elasticity) is the same for all girders. Thus the only variable in determining a girder’s stiffness and the relative load it carries is “I”.

Each lane of this bridge has four girders sharing load: two outside and two middle. The middle girders are much stiffer (much larger “I”) than the outside ones and thus will take much more load. When the middle girders are at maximum allowable load, the outside girders will only be at approximately 48% of their maximum allowable load. Our calculations assume that the full capacity of the middle girders is reached but only 48% of the outside girders’ capacity is used.


4 of 12

Should a load heavier than the middle girders’ capacity be applied, the middle girders will begin to overstress while the outside girders continue to safely take load. Our load rating is designed to keep this from happening – i.e. we do not want any girder to ever overstress.

Girder Analysis: The following table indicates an estimate of the capacity of the bridge’s girders under these assumptions:

* Load is applied roughly to the transverse middle of a bridge lane, i.e. wheels are centered over the lane’s middle girders.

* The section properties, “I”, and “S”, are based on actual measured dimensions at a random location. If a member has corroded significantly, the measurable, competent amount left was used in this computation.

* The girders’ capacity is reduced 15% due to corrosion and / or other damage that we were unable to see but assume is present.

* Girders have continuously braced compression flange, i.e. no localized buckling is possible.

* Steel is Fy = 36 ksi.

* ASD method is used. Allowable bending stress, Fb ~ .67 * 36 = 24 ksi.

* Neither shear nor deflection will govern the design.

* Maximum safe load is when the middle (stiffest) girder is at full capacity.

Results: Each lane’s girders are capable of safely supporting a 2-axle truck with gross weight of 40,000 lb, or a truck and trailer with total gross combined weight of 72,000 lb.

Deck and Substructure Analysis: No analysis was performed on the deck or substructure. It is assumed that these elements have equal or greater capacity than the girders. To confirm this will require additional field investigation and analysis.

Bank Analysis: No analysis was performed on the banks. Both banks currently appear to be functioning acceptably. However, bank B is moderately steep and prone to failure if undercut by erosion or is overloaded. To estimate the load capacity of these elements will require additional investigation and analysis.

SUMMARY AND RECOMMENDATIONS

DECK


5 of 12

Summary. The deck, with the exception of one damaged area, appears in good condition; we assume approximately 90% of its original strength. The damaged area is confined to two planks located approximately 15’ from end B and 8’ from side 1. This damage is likely due to physical impact, perhaps a tree branch falling. The photos in the appendix show this area with a traffic cone.

Recommendations.

* Standard inspection protocol (see below.)

* Repair / replace damaged members.

SUBSTRUCTURE

Summary. The steel substructure, runners and transverse beams, are in medium condition. There is minor to moderate rust throughout but it doesn’t appear to have caused significant strength loss yet.

Recommendations.

Standard inspection protocol (see below.)

GIRDERS

Summary. The girders appear in medium condition with minor to moderate rust throughout. They are of sufficient size, however, that they still have plenty of capacity to support even the heaviest highway trucks, HS20 loading.

Recommendations. Standard inspection protocol (see below.)

ABUTMENTS

Summary. It is questionable whether or not abutments exist – none was observed. It is possible that the girders are placed directly on soil. Regardless, this system appears to be functioning adequately.

Recommendations. Standard inspection protocol (see below.)

BANKS

Summary. End “A” appears stable with plenty of shelf for adequate support.

End “B” has adequate shelf for support, however, the bank may be too steep for long-term stability.

Recommendations.

* Standard inspection protocol (see below.)

* Stream bank stabilization, especially at end “B”. The unprotected banks under the bridge and extending at least 25-feet upstream and downstream should be stabilized with rip-rap armor, rockery wall, or similar method. Design should be by a licensed professional.

LOAD RATING

We assume that the load capacity of the deck, substructure, and banks is at least equivalent to that of the girders though we did not calculate or confirm this.


6 of 12

Our calculations indicate that each lane’s girders are capable of safely supporting an H20 truck of gross vehicle weight 40,000 lb. Thus the total bridge capacity based on girder strength is double that.

Bank “B” appears too steep for long-term stability, though it is currently supporting the girders adequately. Estimation of the load capacity of the banks will require additional investigation.

STANDARD INSPECTION PROTOCOL

* During regular use of bridge, keep alert for: impact damage, excessive rust, cracks, settlement, rot, soft spots, erosion, slope failure, and the like.

* Full bridge inspection no less frequently than every two years.

* Inspection of affected elements after significant storms, high water, impact damage from vehicles, trees, etc.

“PICTURES OF CONSTRUCTION EQUIPMENT” ALL OF THE CONSTRUCTION EQUIPMENT SHOWN HAVE USED

THE HARRINGTON CREEK BRIDGE DURING THE PREVIOUS ROAD PROJECT


Cindy Roessler Page 1 9/30/2016 N:\NR_Department_Administration\NR Reference Material\Vegetation_Management\Revegetation Techniques\Erosion Control Options

EXHIBIT D35: Erosion Control and Site Restoration Measures Erosion Control Options

1. Litter Mulch – chip all removed trees and branches and stockpile outside of grading area. Also, prior to grading, you can scrape off the existing leaf litter and/or organic surface soil and stockpile. For long construction periods, these stockpiles should be covered with tarps to prevent infestation with weed seeds. [Make sure contractors save the chips and litter in a safe place for later use. We have had contractors carelessly chip and store this material in ways that it could not be retrieved for later use.] On small sites, rake a portion of the litter from the surrounding forest onto the newly exposed soil. Do not leave either the construction area or the borrow site bare; the litter most be spread to provide cover so no bare soil is exposed or left exposed. Spread chips or litter so that it is at least 1 inch thick above soil.

2. Native grass straw – purchase native grass straw from native grass seed

companies. Native grass straw is the stem part cut and baled from a native grass field after the seed has been harvested. This straw should not have the weeds that are present in other types of straw bales. In 2008, we purchased native grass straw from Hedgerow Farms at about $15 bale including delivery. Spread straw across site after all grading work (and seeding if applicable) is completed. Straw may need to be crimped into the soil on larger sites, such as by running a piece of track-walking equipment across the spread straw. Spread straw so that it is at least 2 inches thick above soil.

3. Weed-free straw – purchase weed-free straw; often it is rice straw. Our

experience is that sometimes, despite the claim that it is weed-free, this straw may not be. California has a voluntary certification program to regulate the quality of weed-free straw (Guidelines under California Food and Agriculture Code Section 5101 & 5205 For the Certification of Weed Free Forage, Hay, Straw and Mulch); ask for certification records. Spread straw so that it is at least 2 inches thick above soil.

4. Native grass seed mix – spread a native grass seed mix after all grading and

before spreading straw or mulch on the site. Remove all weeds and miscellaneous plant material from surface of soil to be planted; for a particularly weedy area, sometimes it is good to start this weed control work two years before seeding. Native grass seed mixes can be purchased from native grass seed companies. The selection of species in the mix should be appropriate for the field conditions (sunny, shady, wet, dry, rocky, clay, sandy) and should be derived from native grasses collected in the general region of the project site. Beware of seed mixes labeled “erosion control mix” that contain non-native species such as clovers. Although these seed mixes may work fine in pastures and other developed sites, they are not appropriate for spreading in natural areas. Seed mix should be spread at a rate of 40 lbs/acre. Seed should be lightly raked into soil and covered with 1

Cindy Roessler Page 2 9/30/2016 N:\NR_Department_Administration\NR Reference Material\Vegetation_Management\Revegetation Techniques\Erosion Control Options

to 2 inches of straw (see above). If a no-till drill seeder is used, seeding rate can be 30 lbs/acre, no raking is required, but a straw mulch layer should be applied.

5. Sterile wheatgrass hybrid seed – spread sterile wheatgrass hybrid seed

(commercial product known as “Regreen”) which germinates quickly and vigorously once irrigated, but is an annual and will not produce viable seed after one to two years. This grass is suitable in areas that are too shady to support grass growth over the long term but which require erosion control cover in the short term. Remove all weeds and miscellaneous plant material from surface of soil to be planted. Total seed mix rate should be 50 lb/acre. Seed should be lightly raked into soil and covered with 1 to 2 inches of straw (see above).

EXHIBIT D36: Cattle Safety Tips

Animals grazing in the preserves come with some trade-offs for our visitors. In the rainy season, the passage of cattle can cause damage to sections of trail, making the ground muddy, pocked, and unpleasant to walk through. Like all other animals, cows produce manure, so visitors must watch their step. And, though it is rare, there have been some incidents of cattle head-butting people in other parks and rangelands.

Cattle are large animals but are not aggressive by nature. However, if aggravated or threatened, cattle can respond in a potentially dangerous manner. Use common sense around cattle and remember the following:

• Try not to startle the cows. Keep your distance and walk around groups of cows allowing plenty of space.

• Not all animals with horns are bulls, nor are they naturally inclined to charge you. • Cows are protective of their young, so don't get between a calf and its mother, and

don't try to touch them. If you see a stray calf, leave it alone! -- Its mother is probably nearby. Walk wide around the cattle as much as possible.

• Don't approach or touch stray calves. Most likely the cow had gone off to graze, and will return for her calf.

• Keep pets under control or on leash. Cows can't always distinguish between a dog and coyote and may become agitated as the dog approaches. Loose, barking dogs can easily harass or injure livestock.

• If you see an animal in distress, do not attempt to intervene; rather, note the location of the animal and report it to MROSD personnel.

• Do not crowd cattle in a corner, gate area, or against a natural barrier. When cattle feel pressured they may react aggressively or in a panic to escape or protect their young.

SECTION 02 26 00

SCHEDULE FOR EXISTING CONDITIONS

PART 1 ‐ GENERAL

1.1 SUMMARY

A. This Document discloses Reference Documents that are available to the bidders regarding the hazardous materials investigations utilized in preparation of the Contract Documents.

1.2 HAZARDOUS MATERIALS REPORT(S)

A. The Bidder’s attention is directed to the fact that a hazardous materials survey was performed for the structures and is known as:

1. Summary Report: Pre‐Demolition Asbestos Survey, 21 Buildings, La Honda, CA, prepared by SCA Environmental, Inc. and dated July 6, 2016 (SCA Project No: F12076).

Inspection and sampling was conducted by SCA Environmental, Inc. in 2016 and included the following:

1. A visual inspection of all areas of each structure.

2. Destructive sampling for asbestos‐containing materials (ACM) and asbestos‐containing construction materials.

3. Visual identification of mold.

4. Visual quantification of mercury‐containing light tubes and possible PCB‐containing lighting ballasts.

Note that all paints are assumed to contain lead >1000 ppm. Copies of the above referenced report(s) may be reviewed by contacting the Owner.

1.3 HAZARD SUMMARY

A. Asbestos Hazards: Certain existing building components or materials, which may be impacted by the Work of this Project, are known or presumed to contain asbestos.

For a list of asbestos‐containing materials (ACM, >1%), asbestos‐containing construction materials (ACCM, >0.1%), Trace asbestos materials, and non‐asbestos‐containing materials in the buildings and at the site, refer to the Material Matrix Reports attached to this section.




Additional suspect materials identified should be assumed asbestos‐containing until such time as sampling can be performed to verify asbestos content.

B. Lead Hazards: All paints are assumed to contain lead >1000 ppm.

Treat all similar paints and substrates in kind. Note that most building paints contain some lead content. Assume all paints contain >1000 ppm and require demolition dust control procedures for compliance with Cal/OSHA's Construction Lead Standard under 8 CCR 1532.1. Characterize debris from coated materials for possible disposal as hazardous waste. Intact painted elements may be disposed as non‐hazardous waste complying with dust controls and personal protective procedures per Cal/OSHA regulation 8 CCR 1532.1 and California DPH regulation 17 CCR Sections 35001 through 36100.

The following materials were not all tested but, the Contractor, for the purposes of this Contract, shall assume, and manage, them as lead containing.

a. Plumbing components, such as pipes, fittings and solders. b. Roof flashings. c. Mastic and adhesives. d. Coatings/paints on structural steel.

It has not been verified that any paints, coatings, dusts, or materials are “lead free” or below detection therefore all “trigger 1” construction activities, such as demolition of painted surfaces, manual scraping or sanding of painted surfaces, or any work impacting painted surfaces and primed structural steel shall be completed using dust controls and personal protective measures in compliance with the Cal/OSHA Construction Lead Standard, 8 CCR 1532.1.

C. Other Hazards:

1. PCB‐containing Fluorescent Light Ballasts: Fluorescent fixtures shall be treated as having a mix of PCB and non‐PCB ballasts, requiring disposal of impacted suspect units as hazardous waste.

2. Mercury‐Containing Fluorescent Light Tubes/Bulbs: Fluorescent lamps on‐site shall be treated as having mercury content requiring removal and recycling by this contract’s demolition requirements.

3. Mold‐ Mold was identified in various areas based on observations. Moldy materials shall be removed and disposed of in accordance to their other components (asbestos, lead, etc.). Usage of respiratory protection (equivalent to asbestos or lead‐related work) is required during work with moldy materials removal.




1.4 USE OF DATA

A. Environmental consultation was obtained only for the use of the Owner and its Consultants for planning and design stages of this Project. The above mentioned data are not, as a whole, part of the Contract Documents, but the sampling data contained therein can be relied upon by the Contractor to characterize general site conditions, although quantities, friability and other factors may have changed or been altered since the time of inspection.

B. All statements, findings, and interpretations in the above mentioned reports are those of the Survey or Abatement Consultant. The Owner makes no representations, either expressed or implied, as to the completeness or adequacy of the above‐mentioned reports. Bidders are advised that the limited testing of components allow for generalizations in describing the extent of hazardous materials. Specific components or materials, should be checked against the referenced sampling data and the Contract Documents, or be tested at affected locations, prior to disturbance of such components.

C. Bidders shall visit the site and acquaint themselves with the existing conditions.

1.5 PRE‐BID VISIT TO WORK SITE

A. Prior to bidding, Bidders may make their own investigations to satisfy themselves as to the Site and building conditions.

1.6 ASBESTOS SAMPLE LOCATION DIAGRAMS

Drawings provided herein and listed below refer to sample locations only and are not intended to provide locations where hazardous materials are present. Sample location diagrams include samples collected by SCA in June 2016. Refer to Section 1.7 for information regarding locations of identified hazardous materials.

The work covered by this work plan includes the removal, handling and disposal of various hazardous materials in accordance with the Contract Documents and applicable federal, state and local regulations at the above designated site. A copy of this Abatement Work Plan is to be posted on‐site during the abatement work. I. SUMMARY OF WORK

X Removal and disposal of asbestos‐containing materials (ACM) and asbestos‐containing

building/construction materials (ACBM / ACCM) as part of demolition activities. X Spot abatement and disposal of wastes for primers and lead‐containing paints on

structural steel elements prior to torching, cutting, etc., including dust controls and personal protective procedures in compliance with Cal/OSHA's Construction Lead Standard, 8 CCR 1532.1 and CDPH regulation 17 CCR Sections 35001 through 36100. Warning ‐ Surfaces or building materials scheduled for torch cutting or other "hot" work may have previously been coated with paints with chromium, cadmium or other heavy metals. Spot removal of paints may not be sufficient to completely control fume release. The contractor is required to:

(1) use the appropriate equipment and work practices to prevent lead releases and possible exposures to tenants, visitors and construction personnel;

(2) protect or clean surfaces so that dislodgeable lead contamination (i.e. contamination which can be identified by wipe sampling, where lead may be used as an indicator for other heavy metals) is not left behind, and

(3) take appropriate measures to protect their employees against exposures to lead or other heavy metals

X Scraping of loose and peeling paints as required for disposal of intact painted elements as non‐hazardous waste, including associated dust controls and personal protective procedures in compliance with Cal/OSHA's Construction Lead Standard, 8 CCR 1532.1 and CDPH regulation 17 CCR Sections 35001 through 36100.

X Demolition, removal and disposal of surfaces with lead‐containing paints (LCPs) whereby airborne exposures may exceed the permissible exposure level, requiring such work to be completed by CDPH Certified Lead Workers and Supervisors in compliance with Cal/OSHA's Construction Lead Standard, 8 CCR 1532.1 and CDPH regulation 17 CCR Sections 35001 through 36100.

X Removal of mold‐impacted substrates as part of demolition procedures. X Removal and disposal of PCB‐containing ballasts, as designated. X Removal and recycling of mercury‐containing lamps, as designated.

V. SECURITY Arrange site security with the Owner at the beginning of the job. Please note the following: 1. Abatement contractor employees and equipment will be required to enter the site at

entrance ways designated by the Owner. No employee may enter the site at any other point than the designated entryway(s).




02 26 00 ‐ 5

2. Abatement contractor’s equipment will be stored and secured in an area agreed upon by the Owner and the Contractor.

3. The Abatement contractor will be responsible for providing temporary site security at

building penetrations created by the demolition and abatement.

4. Refer to the Contract documents for additional site security requirements for the project.

VI. SPECIAL CONDITIONS

Design: 1. The minimum negative pressure level for this project is –0.02” w.g. at all locations. The

Abatement contractor is responsible for maintaining this level during all work activities, including bagout and until satisfactory clearance air results have been received and notice of clearance is provided by the Environmental Consultant.

2. Negative pressure recording: the Abatement contractor is responsible for recording negative pressure as follows: a. Negative pressure will be recorded throughout the entire project, including inspections,

clearance testing, and at all times until the Consultant provides a final clearance notice. b. At least one spare manometer must be kept on site at all times. a. A printout of recordings must be transmitted to the Environmental Consultant by the

Abatement Contractor each day.

3. Waste will be removed from the structures each night and disposed of in approved waste receptacles in the designated loading areas. Waste receptacles will be properly labeled and locked each night.

Asbestos Sampling: 1. PCM Analysis: Analysis of PCM samples shall follow the procedures outlined in NIOSH

method 7400 and within these Contract Documents.

2. TEM Analysis: The U. S. Environmental Protection Agency passed regulations for schools under the Asbestos Hazard Emergency Response Act (AHERA), which are found in 40 CFR Part 763 "Asbestos Containing Materials in Schools". This regulation states that all abatement work shall be evaluated upon completion by collecting air samples using aggressive sampling techniques and that such samples shall be analyzed using Transmission Electron Microscopy (TEM). TEM analysis turnaround times shall be 24 hours, unless otherwise indicated.

3. If TEM sampling is performed, the sampling and analytical criteria in the AHERA regulation for schools shall be viewed as the preferred method for determining that any asbestos abatement project in any building has achieved a satisfactory level of cleanliness. SFIA's Environmental Consultant shall collect air samples from all work areas using aggressive sampling and TEM analysis, unless otherwise noted. The Owner reserves the right to determine the quantity of clearance air samples to be collected for each subzone. Sample




02 26 00 ‐ 6

results in excess of 70 asbestos structures per square millimeter of filter area (equivalent to 0.018 s/cc, corrected for a 1,500 [1,200 ‐ 1,800] liter sample volume as appropriate) will require cleaning, inspection, and resampling of the affected area at the Contractor's expense. Z‐testing shall NOT be used as a means for comparing the interior levels against those of the exterior for the purpose of clearing the Work Area.

4. The Owner shall pay the Environmental Consultant's costs of the final round of visual inspections, air sampling, and/or PCM and/or TEM analyses that will meet the asbestos abatement specification. All rounds of visual inspections, air sampling, and PCM and/or TEM analyses that fail to meet the contract criteria shall be borne by the Contractor. For the purpose of this paragraph, visual inspection includes the area isolation inspection, pre‐encapsulation inspection, and final area clean‐up inspection.

5. During asbestos‐related work, perimeter sample results may be collected by the designated Environmental Consultant (Industrial Hygienist). These samples will be analyzed by Phase Contrast Microscopy (PCM). Sample results that are in excess of the background level or 0.01 fibers per cubic centimeter (f/cc) Project Action Level may be forwarded for analysis by Transmission Electron Microscopy (TEM) with a 12‐hour turnaround specified. Handling, shipping, and analysis charges (including the Environmental Consultants time and expenses) will be paid for by the Contractor. Any sample results in excess of 0.018 structures/cc will require cleaning, inspection, and resampling of the affected area at the Contractor's expense.

Lead Sampling:

1. During all lead hazard‐related work, such as demolition, torching and welding activities, etc., as applicable, perimeter air sample and/or lead wipe sample results may be collected by the SFIA Environmental Consultant (Industrial Hygienist). These samples will be analyzed by flame atomic absorption or ICP/MS. Wipe sample results which are in excess of the of 40 micrograms per square foot for adjoining zones on two consecutive samplings (or two consecutive days) or for adjoining floor areas on any occasion will require isolation and clean‐up of the affected areas. Air sampling results in excess of 1.5 micrograms per cubic meter will require isolation of the work area and amendment of work procedures and/or clean‐up of the affected areas. Resampling of the affected areas and handling, shipping, and analysis charges (including the Environmental Consultant's time and expenses) for additional sampling required to show background levels below these construction lead standards shall be borne by the Contractor.

Submittals: 1. All pre‐construction submittals shall be forwarded to the Owner and the Owner’s

VII. SUMMARY OF SURVEY RESULT AND CONDITIONS Asbestos: For a list of ACM and ACBM / ACCM, refer to the Materials Matrix Reports attached to Section 02 26 00: Hazardous Materials Existing Conditions. Additional suspect materials identified should be assumed asbestos‐containing until such time as sampling can be performed to verify asbestos content. Lead: All paints and are assumed to contain lead and shall be treated as such. Various paints may require specialized handling and disposal. Contractors shall comply with the Cal/OSHA lead in construction regulation (8 CCR 1532.1) for all work activities, and all coated surfaces shall be considered to contain some lead. Treat all similar paints and substrates in kind. Note that most building paints contain some lead content, and require demolition dust control procedures for compliance with Cal/OSHA's Construction Lead Standard under 8 CCR 1532.1, as well as the Welding, Cutting, and Heating of Coated Metals under 8 CCR 1537. Characterize debris from coated materials, vinyl flooring, etc. for possible disposal as hazardous waste. Intact painted elements may be disposed as non‐hazardous waste complying with dust controls and personal protective procedures per Cal/OSHA regulation 8 CCR 1532.1 and CDPH regulation 17 CCR Sections 35001 through 36100, if the total and leachable lead contents of the waste streams are below 1000 mg/kg and 5 mg/liter (WET and TCLP tests).

1.3 DEFINITIONS

A. Asbestos Work Class: Activities for removing asbestos materials by categories are as follows:




1. Work Class I: Activity involving removal of TSI and surfacing asbestos‐containing materials (ACM) or friable presumed asbestos‐containing materials (PACM).

2. Work Class II: Activity involving removal of asbestos‐containing materials (ACM) not in Work Class I. Excavation/grading of soil is a Class II activity.

3. Work Class III: Repair and maintenance operations where TSI or surfacing is likely to be disturbed, which fits within one standard glovebag or waste container under sixty (60) inches.

4. Work Class IV: Maintenance and custodial activities during which employees contact but do not disturb PACM or ACM and activities to clean‐up dust, waste and debris resulting from Work Class I, II, and III activities.

B. Abatement: Primary work involving the removal, containment, control or treatment of hazardous materials.

C. Asbestos: A generic name given to a number of naturally occurring hydrated mineral silicates that possess a unique crystalline structure, are incombustible in air, and are separate into fibers. Asbestos includes any material that contains greater than 0.1 percent by weight in the asbestiform varieties of chrysotile (serpentine); crocidolite (riebecklite); amosite (cummingtonite‐grunerite); anthophyllite; tremolite; and actinolite. For the purposes of determining respiratory protection and worker protection both the asbestiform and non‐asbestiform varieties of the above materials and any of these materials that have been chemically treated or altered shall be considered asbestos.

D. Asbestos‐Containing Material (ACM): Any material which contains more than one percent (>1%) asbestos by weight for the purposes of abatement, waste disposal and fiber controls specified under this Contract.

E. Asbestos Containing Building or Construction Material (ACBM or ACCM): Any material which contains more than one tenth of one percent (>0.1%) asbestos by weight requiring personal protection, dust controls, Contractor registration, and worker training in compliance with Cal/OSHA regulation 8 CCR 1529. For waste disposal purposes, ACBM and ACCM greater than 0.1% by weight and less than 1% by weight is classified as non‐hazardous waste, although it is a regulated material under Cal/OSHA.

F. Hazardous Materials Control: Incidental work procedures for control of releases of project‐ related hazardous materials, including containment, enclosure, wetting, controlled renovations and demolition procedures, and removal and disposal.

G. Hazardous Waste:

1. Waste material, including asbestos, loose and peeling lead‐based paints, and any other material which requires management, handling transport, treatment, storage or disposal according to the requirements of the Federal Resource, Conservation and Recovery Act (RCRA) and associated regulation 42 U.S.C. 6901 et seq. and 40 CFR Part 260 et seq.) or the




California Hazardous Waste Control Law and associated regulations (Health and Safety Code 25000 et seq. and 22 CCR 66260 et seq.).

2. References to hazardous material or contaminated material incorporate definitions of hazardous pollutants, hazardous contaminants, hazardous material, hazardous substance, hazardous waste, toxic pollutants and toxic substance applicable in accordance with Federal, State, regional and local statutes, laws, regulations and policies.

H. Presumed Asbestos Containing Material (PACM): Thermal system insulation and surfacing material found in buildings constructed no later than 1980.

I. Naturally Occurring Asbestos (NOA): Soil or rocks containing >0.25% asbestos that has not been modified by a manufacturing process. CalOSHA classifies base rock as NOA; whereas asphalt or concrete as non‐NOA. NOA that contains >1% is also a CalOSHA Class II ACM.
