Limited Hazardous MaterialsSurvey ReportContra Costa CollegeApplied Arts Building2600 Mission Bell DriveSan Pablo, California1. Executive Summary

The following is a report of the limited hazardous materials survey conducted byRemington Caldwell, California Certified Asbestos Consultant (CAC) and CaliforniaDepartment of Public Health (CDPH) Inspector Assessor with RGA Environmental, ATerracon Company, (RGA). The survey was performed on June 13, 2016 in the AppliedArts Building of the Contra Costa College Campus located at 2600 Mission Bell Drive inSan Pablo, California.

The scope of the survey was to identify hazardous materials including asbestoscontaining materials (ACMs) and lead containing paint with the potential to be impactedby the Chiller Replacement Project as depicted in drawing set dated June 13, 2016 andprovided by the District. The survey area was limited to building areas and materials withthe potential to be disturbed by the planned project.

During the survey, eight (8) homogenous suspect ACMs were identified. Three (3) of thehomogeneous suspect ACMs tested positive for asbestos content.

Nine (9) painted finishes were sampled for potential lead content. Two (2) of the paintedmaterials sampled were reported above the laboratory detection limit for lead.

Table I summarizes the materials identified as ACMs. Table II summarizes the materialsthat were determined to be negative for asbestos content. Table III summarizes the leadconcentrations of the materials sampled.

2. Scope of Work

The scope of the survey was as follows:

· Inspect the survey area for the presence of suspect ACMs and lead-containing paintwith the potential to be impacted by the planned Chiller Replacement project.

· Collect a representative number of samples of suspect ACMs following the NationalEmissions Standard for Hazardous Air Pollutants (NESHAPs) protocol for samplecollection for a renovation survey. Analyze asbestos bulk samples using polarizedlight microscopy (PLM) in accordance with EPA’s July 1993 method for thedetermination of asbestos in bulk building materials - EPA 600/R-93/116.

· Collect paint chip samples of the primary painted surfaces within the survey areasuspected to be lead containing for purposes of compliance with CaliforniaDepartment of Occupational Safety and Health (DOSH) Lead in ConstructionStandard. Bulk samples and paint chips were analyzed at an accredited laboratory byFlame Atomic Absorption (AA) for Total Lead reported in parts per million (ppm).

· Submit written report including analytical results, regulatory requirements,conclusions and recommendations.

3. Methods and Sampling Strategy

Visual InspectionAccessible materials were visually inspected in the survey area using the methodspresented in the federal Asbestos Hazard Emergency Response Act (AHERA) regulations(40 CFR, Part 763) as a guideline. AHERA was originally only applicable to schools,however state and federal Occupational Safety and Health Administration (OSHA) andAsbestos School Hazard Abatement and Reauthorization Act (ASHARA) have adoptedthe AHERA sampling methodology for all buildings subject to demolition or renovation.

Bulk Sampling of AsbestosBulk samples of all suspect ACM homogeneous materials were collected. Ahomogeneous material is defined as a surfacing material, thermal system insulation, ormiscellaneous material that is uniform in color, texture and age of construction. Examplesof homogeneous materials include:

· Pipe-insulation produced by the same manufacturer and installed during the sametime period;

· Resilient flooring of identical color and pattern;

· Troweled on surfacing materials located in contiguous areas.

The survey area was visually inspected for the presence of suspect materials. Asmaterials were identified, bulk samples were obtained with the aid of a coring device orother hand tool and placed into individual sampling bags. Each sample was given adiscrete identification number and recorded on field notes as well as chain-of-custodyforms. Refer to accompanying tables and appendices for details on material samplelocations and results. Bulk samples were transported to EMLab P&K (EML) in SouthSan Francisco, California.

Bulk Sampling of Suspect Lead Containing MaterialsPaint chip and/or suspected lead containing materials were collected using a hand scraperand were placed into individual plastic sampling containers. Each sample was provided adiscreet sample number, which was recorded on a chain-of-custody form. Samples weretransported to QuanTEM Laboratories (QuanTEM) in Oklahoma City, Oklahoma foranalysis.

Bulk Sample Analysis - AsbestosEML is accredited under the National Institute of Standards and Technology's NationalVoluntary Laboratory Accreditation Program (NVLAP) for determination of asbestosfibers in bulk materials.

All samples were analyzed using polarized light microscopy (PLM) techniques inaccordance with methodology approved by the U.S. Environmental Protection Agency(EPA). As set forth in the Code of Federal Regulations, 40 CFR Part 763, Appendix A toSubpart F, Section 1.2 and 1.7.2.4, the lower limit of reliability detection for asbestosusing the PLM method is approximately one percent (1%) by volume. Cal-OSHA definesasbestos containing construction materials (ACCM) as those materials having asbestoscontent of greater than one tenth of one percent (>0.1%).

When None Detected (ND) appears in this report, it should be interpreted as meaning noasbestos was observed in the sample material above the reliable limit of detection for thePLM method.

Note: under EPA assessment criteria, if a single sample of a homogeneous material testspositive for asbestos, all homogeneous materials within that building are considered to beasbestos containing.

Bulk Sample Analysis – LeadAll paint samples were analyzed for lead content using the Flame Atomic Absorptionspectroscopy in accordance to EPA Method SW846-3050B-7000B. When “<” appears inthe lead sample report, it should be interpreted as meaning below analytical detectionlimit.

7. Regulatory Requirements

Asbestos

Building materials within the survey area contain asbestos in concentrations greater thanone tenth of one percent (0.1%). Impacting materials containing greater than 0.1%asbestos either through repair, maintenance, renovation or demolition activities triggersnumerous regulations enforced by such agencies as OSHA (worker protection) and EPA(environmental exposure, transportation and disposal).

Listed below are the regulations that apply if the materials are removed:

· Any individual who contracts to provide health and safety services relating to ACMsmust be certified by Cal-OSHA as either a Certified Asbestos Consultant or a SiteSurveillance Technician. The activities they are certified to provide include:conducting asbestos surveys; writing work plans or specifications for abatement;monitoring the work of abatement contractors; collecting air samples; anddetermining if the work area is safe for re-occupancy by non-asbestos workers.Regulation: Cal-OSHA 8 CCR 1529 (q)(1).

· If more than 100 square feet of materials that contain greater than 0.1% asbestos willbe abated, they must be abated by a Cal-OSHA registered asbestos abatementcontractor. Regulation: Cal-OSHA 8 CCR 1529 (R).

Limited Hazardous Materials SurveyChiller ReplacementContra Costa CollegeSan Pablo, California

Page 7

· ACMs that are classified by OSHA as other/miscellaneous materials are present.Removal of these materials is considered a Class II activity according to Cal-OSHAregulations. Work practices and engineering controls for Class II work are specifiedin Cal-OSHA 8 CCR 1529 (g) (7-8).

· If more than 100 square feet or 100 linear feet of friable ACM will likely be removed,the abatement contractor must notify the Bay Area Air Quality Management Districtten (10) days prior to removing the material. Regulation: BAAQMD Regulation 11,Rule 2.

· Friable ACMs greater than 1% asbestos must be manifested, transported, anddisposed of as hazardous waste in accordance with the Department of Toxic andSubstances Control (DTSC), a division of Cal-EPA. DTSC regulates disposal ofasbestos waste. DTSC issues U.S. EPA hazardous waste generator identificationnumbers.

Lead-Containing Materials

Lead-containing paint was identified during the survey. Impacting lead-containingmaterials either through renovation or demolition activities triggers numerous regulationsenforced by such agencies as OSHA (worker protection), EPA (environmental exposure,transportation and disposal), and Department of Public Health (DPH).

Listed below are the regulations that apply if the lead containing materials are impactedduring renovation activities:

· Federal OSHA as well as California OSHA regulates all worker exposure duringconstruction activities that impact lead-containing materials. California OSHAenforces the Lead in Construction Standard in Title 8 CCR 1532.1. The scope coversconstruction work where employees may be exposed to lead during such activities asdemolition, removal, surface preparation for re-painting, renovation, clean-up androutine maintenance. The OSHA specified method of compliance includes respiratoryprotection, protective clothing and equipment, housekeeping, hygiene facilities,medical surveillance, and training, among other requirements.

· California OSHA requires Department of Public Health Lead-Related Constructiontraining if any lead related construction work in public buildings will exceed OSHA’spermissible exposure limit (PEL) for lead.

· Disposal of all lead-containing paint and bulk materials is regulated at concentrationsat or exceeding 1,000 ppm as stated in 40 Code of Federal Regulations (CFR) Part263 - Land Disposal Regulations and Title 22, Division 4 Environmental Health ofthe California Administrative Code. Lead containing materials that exceed 50 ppmmust be additionally analyzed to determine possible waste disposal restrictions withrespect to lead. However, lead related work at any lead concentration is regulatedunder the OSHA statutes.

8. Recommendations to Implement Regulatory Requirements

Asbestos

· Develop a performance abatement specification or work plan for the removal orimpact of the ACMs identified in the survey that will likely be disturbed by theplanned seismic improvement project. The purpose of an abatement specification isto clearly define the scope of work for more competitive and accurate bidding as wellas to reduce the number of costly delays and change orders during the project.

· Conduct a pre-bid job-walk for abatement contractors in order to obtain the mostcompetitive pricing.

· Retain a Certified Asbestos Consultant or Site Surveillance Technician to provide on-site construction supervision of the asbestos abatement contractor to ensure utilizationof proper work practices as stated in the work plan or specification. The Consultantalso ensures that all local, state and federal regulations are followed and that theproject remains on schedule. The on-site Consultant generates documentation ofcontractor work practices and training, and asbestos air sampling results. The on-siteConsultant also ensures that all asbestos materials are removed by the abatementcontractor and properly manifested.

· Request the Asbestos Consultant to collect a sufficient number of air samples on adaily basis to validate that the abatement contractor is not causing any releases ofairborne asbestos fibers outside their work area.

· Request the Asbestos Consultant to visually review the work of the abatementcontractor to verify that all the ACMs are abated. If the work areas pass the visualclearance, then final air clearance samples are collected to ensure that the area is safefor re-occupancy, or unregulated work.

· Request a final written report outlining all activities that transpired throughout thecourse of the abatement project.

Lead-Containing PaintLead containing debris that will be landfilled should be classified as hazardous waste iflead waste concentrations exceed either the total lead concentration or soluble leadconcentration regulatory limits.

We recommend the following actions prior to the start of renovation:

· Use only trained workers for disturbance of building components containing lead.All demolition work should be performed in accordance with the OSHA Lead inConstruction Standard, Title 8 CCR 1532.1. Removal of lead-based paint should beperformed by Department of Public Health Lead Related Construction trainedworkers.

· Worker exposure, environmental monitoring, and proper engineering controls shouldbe implemented throughout the lead related work.

· Contractor should adhere to OSHA and other applicable state and local regulationsfor worker protection, hazard communications, work practices, engineering controlsand proper waste disposal.

· Proper waste stream categorization is required for the disposal of lead-containingmaterials such as paint debris, ceramic tile, and painted building components (intact)in accordance with the Department of Toxic Substance Control (DTSC). Thedisposal of lead-containing materials shall be coordinated with the landfill.

The test report shall not be reproduced except in full, without written approval of the laboratory. The report must not be used by the client to claim product certification, approval, or endorsement by NVLAP, NIST, or any agency of the federal government. EMLab P&K reserves the right to dispose of all samples after a period of thirty (30) days, according to all state and federal guidelines, unless otherwise specified.

Inhomogeneous samples are separated into homogeneous subsamples and analyzed individually. ND means no fibers were detected. When detected, the minimum detection and reporting limit is less than 1% unless point counting is performed. Floor tile samples may contain large amounts of interference material and it is recommended that the sample be analyzed by gravimetric point count analysis to lower the detection limit and to aid in asbestos identification.‡ A "Version" indicated by -"x" after the Lab ID# with a value greater than 1 indicates a sample with amended data. The revision number is reflected by the value of "x".
