experience in this field is

substantiated by our selection for several long-term, or on-call contracts for dam engineering

services from clients, including: California Department of Water Resources (DWR), U.S. Bureau of

Reclamation, U.S. Fish and Wildlife Service, Natural Resources Conservation Service, U.S.

Environmental Protection Agency, and the U.S. Army Corps of Engineers (USACE). Through these

contracts and dam safety contracts with national, regional, and local water agencies and utilities, GET

staff members have provided dam engineering services in virtually every state in the nation.

GEl Consultants, Inc. 1 1


Subconsultant

Included on the GET team are members of the

firm formally known as Winzler & Kelly, who will

bring hydraulic and hydrologic engineering and

environmental services to the Jameson Canyon

Reservoir Project. Winzler & Kelly, a 60-year

provider of multi-disciplined engineering services,

joined forces with GHD in 2011 to create a new

leader in environmental and infrastructure

engineering. GHD is now one of the world’s

leading engineering, architecture, and

environmental consulting companies. Established

in 1928, GHD employs more than 6,500 people across five continents in more than 100 offices.

GHD is wholly-owned by its employees.

The teaming of GET and GHD provides the City with the advantage of quicker project initiation

and completion, as team members have previous knowledge and working experience of the Jameson

Canyon project. GET’s proposed project manager, Mr. Mark Freitas, worked on the 1994

Woodward-Clyde Consultants siting study; and, Ms. Toni Bertolero was the GHD project manager

for the development of the City’s 2010 Urban Water Management Plan.

Project Understanding

The main goal of the services requested is updating of the 1994 Feasibility and Siting Study for the

Jameson Canyon Reservoir Project, prepared by Woodward-Clyde Consultants. The project

explored the potential for water storage at several sites in the Jameson Canyon area, which would

provide up to one-year of operational and/or emergency storage (approximately 3,000 to 4,000 acre-

feet) near the City’s service area. The new study will primarily review the previous site development

concepts; update costs to current price levels; and review the major environmental issues associated with dam and reservoir development.

The 1994 feasibility study included an evaluation of 10 alternative dam sites having reservoir

capacities between 450 and 2,000 acre-feet. Reservoirs storing up to 4,000 acre-feet were also

considered to address water supply needs for drought protection and to offset state restrictions on

delivery rates during parts of the year. Three alternative sites (II), I, and J) were selected for further

study through a ranking process based on an evaluation of operational, geotechnical, and regulatory design criteria. The analysis included rough estimates of construction costs. Conceptual project

designs, quantities, and associated costs were developed for these three highest ranked sites (D, I,

and]); however, some sites considered alternative reservoir sizes, such as 12 and 13. The 1994

conceptual designs were based on limited geologic and geotechnical exploration at each site,

availability and cost of dam construction materials, California Division of Safety of Dams (DSOD)

design criteria, operational criteria, and available cost information on projects of a similar size and

scope. The conceptual designs were used as a basis to estimate construction costs at each site.

As referenced in the Request for Proposals, the City is interested in evaluating and updating

feasibility of sites D2,12, and 13 (Sites D and I shown on FIGURE 2). In the 1994 study, Sites D

and I were found to be suitable sites from a technical perspective and more economically feasible

than Site J, which had significant geotechnical problemsin the dam foundation, very large landslides

upstream of the dam axis, and a significant and costly inlet/outlet works (tunnel). During

development of conceptual designs in 1994, Sites D and I were considered to have stable abutments and only minimal potentials for foundation seepage. However, numerous small shallow mudflows

were observed on the abutment areas. Site D2 was conceptually designed with a zoned earthfill dam

with a height of about 140 feet and a storage capacity of 650 acre-feet. Sites 12 and 13 were also

designed with zoned earthfiJl dams with heights of 160 feet and 190 feet and storage capacities of

1,760 and 4,000 acre-feet, respectively. The inlet/outlet works at Sites D and I were assumed to be

cut-and-cover concrete encased steel pipes along the base of one abutment. These conceptual

design considerations will be revisited during execution of the project as described in the Scope of

Work, addressed later in this proposal.

In addition to the GET projects included in Table 2 and Appendix B, personnel from GHD have

performed several projects for the City addressing water planning and environmental considerations

that will have a significant impact on the update to the Jameson Canyon feasibility and siting study. These projects include:

� 2010 Urban Water Management Plan, City of American Canyon, CA: The project included projecting supply for normal and dry years over the next 20 years for long-range

planning of water supply and urban development. One of the water supply projects

includes Jameson Canyon Reservoir for potential new surface water supply.

� Water Storage Tanks Mitigated Negative Declaration and Environmental Permitting, City of American Canyon, CA: The project included CEQA evaluation

and permitting efforts for the American Canyon Tanks project for construction of a 2.5-

million gallon potable water tank and a 1.0-million gallon reclaimed water tank located in

California red-legged frog habitat and in a highly visible hillside east of the City. The

project involved coordination of data collection and background studies, and authoring of the Initial Study and Mitigated Negative Declaration.

� Commerce Boulevard Recycled Water Main, City of American Canyon, CA: The project included extended the existing recycled water main on Commerce Boulevard to

the intersection with Green Island Road and consisted of approximately 1,000 linear feet

of new 12-inch main. The project also replaced four potable water irrigation services with

recycled water services helping the City meet its goal of lowering the overall potable water demand in the area.



Scope of Work

The GEI/GHD Team will address all of the components requested in the RFP. However, based on

our experience performing similar projects, we propose performing the work in the following,

slightly modified, sequence. Staffing level, personnel hours, and costs to perform each of the below

tasks is included in the Cost Proposal, which has been submitted concurrently with this

Qualifications Proposal, but separately in a sealed envelope per the RFP.

Task 1 - Kick-off Meeting and Project Management

Task I will include the following subtasks:

Subtask IA - A kick-off meeting will be held with City and consultant staff to make broader

introductions with the project team and ensure clear communication and a common

understanding of project purpose. We will review the project goals and objectives, project

stakeholders, and project schedule with milestones and deliverables. We would also obtain

any additional relevant documents and/or data from the City for review in the following task.

Subtask lB - GET will provide project management services including communication and

coordination with the City, coordination of the subconsultants, managing subconsultant

invoicing and payment, and preparing invoices and progress reports in accordance with the

City requirements. Regular internal communication will be established. GET will lead bi-

weekly (as a minimum) project team meetings via teleconference. These conference calls will

focus on scope and schedule of the planned work for the upcoming weeks, issues that affect

the performance of the work and potential changes in scope and schedule.

Deliverables: Kick-off meeting minutes

Task 2 - Data Review, Analyses and Preparation of Technical Memorandum

Task 2 will include the following subtasks:

Subtask 2A - GET will review the 1994 Feasibility and Siting Study for the Jameson

Reservoir Project prepared by WCC, as well as relevant documents or data released since the 1994 publishing of the feasibility study.

The Team will perform a site reconnaissance to observe the dam sites and planned borrow

areas, assuming the City will be able to provide site access during the study phase. We will

obtain and review updated aerial photos of the site and geologic and seismic hazard maps

and publications, to evaluate recent landslide activity and to assess geologic conditions and seismic setting at the dam sites and planned borrow areas.

Subtask 2B - The Team will update the existing siting information at Dam Sites D and T.

Particular attention will be applied to new or additional key criteria that may impact the

geotechnical and geologic conditions, hydraulic and hydrologic design criteria, DSOD



criteria, or environmental constraints. We will evaluate DSOD criteria for design and

permitting of dams, focusing on regulatory issues that now exist and could have relevance to

the conceptual designs prepared in 1994. These criteria may include seismic evaluations,

stability, zoning and filter criteria, and safe passage of storm flows.

Environmental constraints to be reviewed include California Natural Diversity Database

(CNDDB), and permitting requirements. These reviews will be performed in the context of

the city’s current water demands, and will include review of the 2010 Urban Water

Management Plan, water master plan, and other water supply documents provided by the

city.

Budget-level costs to construct the dams and appurtenant structures will be updated based

on the above described data review and by using up-to-date references and cost estimating

techniques. GET has a very strong track record with respect to developing budget estimates

from dam construction that hold up from the planning phase through project

implementation.

Subask 2C - We will prepare a technical memorandum summarizing the review. This

document will include a discussion on the water supply demands and projections from the

2010 Urban Water Management Plan, the impacts of the proposed reservoirs, and

recommend an implementation plan for further engineering and environmental work.

Completion of the technical memorandum will also include a presentation to the City’s Blue

Ribbon Committee on Water Resources, and a follow up meeting with the Committee to

address comments. Per the steps outlined in the RFP, the technical memorandum will be

submitted in the following the sequence:

1. Submit an administrative draft technical memorandum for city staff review and

comment.

2. Submit a revised draft technical memorandum for review by the Blue Ribbon

Committee on Water Resources.

3. Attend up to 2 meetings of the Blue Ribbon Committee on Water Resources to

address committee comments.

4. Submit a revised draft technical memorandum for city staff review and comment.

5. Submit a final technical memorandum.

Other Information

Conflict of Interest Statement

Neither GET nor GHD have any recent, current, or anticipated contractual obligations that would

present a conflict of mterest to the City, or to the Jameson Canyon Project.

Contract and Insurance Documentation

For over 40 years, GET has provided professional engineering services to its clients, which is

demonstrated in part by many long-term client relationships. This level of service and commitment

is applied to all our projects and clients, with the hope that each one will lead to long-lasting

relationships and a successful project. GET’s record and relationships are very important to us;

accordingly, we carefully evaluate all aspects of our business, including managing risk.

GET’s Risk Management Committee is responsible for reviewing contract terms and conditions to

ensure that GET is responsible for its own professional liability, and that our professional liability

insurance provides adequate coverage for GET’s negligent acts, errors, and omissions, including, if

necessary, defending GET’s work. The Risk Management Committee has reviewed the sample

agreement included in the RFP, and has several comments on the indemnification language, which

are typical for many of our public clients. If selected for this project, we would like to meet with the

City to review the sample agreement to ensure the indemnification language is consistent with

California State Law and provides the City with the required insurance coverage for the project.

GET will provide and maintain policies of insurance according to the sample Agreement. We are

confident that we can develop contract terms that meet the City’s and GET’s risk management

needs.

Client Endorsement

Each year, over 80 percent of our business is derived from satisfied, repeat clients. As such, we

routinely solicit feedback from our clients on how our service can improve and how we can better

Seismic Stability Analyses, El Dorado Forebay Dam El Dorado Irrigation District, El Dorado County, California

The El Dorado Forebay

Darn and Reservoir

(Forehay) is a vital hub

in the water supply for

the El Dorado Irrigation

District (EID), which

has provided water

supply and hydroelectric

benefits for over 80

years.

GEl has assisted EID since 1999

with engineering assessments

and analyses of the five dams

and related facilities (Silver Lake,

Echo Lake, Gaples Lake, Lake

Aloha, and El Dorado Forebay)

that comprise Project No. 184.

The objective of our work has

been to bring the project into

FERC compliance with a particular

emphasis on El Dorado Forebay

Dam.

El Dorado Forebay Dam is a

homogeneous embankment

dam constructed of sandy silt

material that has been under

regulatory scrutiny for many

years. Due to the dam’s age and

the identification of potential

dam safety deficiencies, EID

is evaluating the adequacy of

seismic stability, spillway capacity,

and appurtenant structures.

GET is providing dam safety

engineering consultation services

to comprehensively evaluate

regulatory and safety requirements

related to the existing El Dorado

Forebay Dam facilities (Phase

1) and, if determined necessary,

will pursue system reliability/

strategic initiatives by evaluating

alternatives to mitigate and

improve the functionality of the

El Dorado Forebay Dam facilities

(Phase 2).

GEl has completed the subsurface

field investigations, laboratory

testing, and has developed

material properties for use in

embankment stability analyses.

Both static and seismic stability

reevaluations were required. For

seismic stability, GEl is using

state-of-the-practice non-linear

finite difference embankment

and foundation modeling to

predict embankment deformation.

As input for the analysis, GET

developed seismic ground motions

for the Spring Valley fault and

selected four earthquake records to

model. The FLAG model was used

to run over 20 cases to develop

sensitivity analyses for each of the

four earthquake records. Results

show that expected embankment

deformations and settlements are

less than predicted with simplified

seismic analysis procedures.

The FERG and DSOD have

reviewed and accepted the

seismic deformation analyses and

concluded that less expensive,

freeboard modifications are

necessary.

properties for geotechnical

analyses and design. Seismic

hazard analyses were performed

to develop appropriate seismic

input parameters for slope

stability analyses. Seepage and

slope stability analyses were

performed on cross sections of the

embankments for both existing

conditions and remediated

conditions. The existing spillway

capacities were analyzed and

hydrologic and hydraulic analyses

were performed for each dam.

San Justo Reservoir Reoperation Project San Benito County Water District, Hollister, CA

San Justo Reservoir is

an off-stream reservoir

constructed by the

United States Bureau

of Reclamation located

about 5 miles south of

the City of Hollister,

California.

The reservoir was created by

constructing a 153-ft high main

dam at the southern end of the

valley and an 80-ft high auxiliary

dike at the northern end of

the valley and provides both

regulation and carryover storage.

Because of the complex geology

at the auxiliary dike site,

significant reservoir leakage

has occurred throughout its

operational history, which has

contributed to the occurrence of

landslides in the natural slopes

outside of the reservoir rim.

While the geologic structure is

fundamentally understood, the

site conditions are complicated by

steep terrain, and external factors

such as seasonal precipitation and

continuously fluctuating reservoir

and groundwater levels. As a

result of the landslides, water

storage levels were reduced by

about 15 feet to an administrative-

level in 2005, which has

significantly reduced the incidence

of sliding.

GET has been engaged by the

operator, San Benito county Water

District, to develop a solution for

recovering the lost storage while

still protecting the surrounding

environment and the safety of

adjacent facilities. Proposed

solutions must also satisfy the

U.S. Bureau of Reclamation, the

reservoir owner. Reclamation is

actively engaged in evaluating

site conditions and ensuring

safe operation. GET performed

a site assessment to determine

viable approaches to satisfying

the needs of the operator and

owner, and consequently,

developed an analytical approach

to gradually increase storage in

the reservoir through phases of

modified reservoir operations.

The approach is based on the

principles of wave theories and

groundwater hydraulics, and

uses incremental pulsing of the

reservoir stage and evaluation

of the downstream groundwater

levels and landslide behavior

as means of determining

safe operation practices for

the reservoir. Preliminary

assessment of the first cycle of

reservoir operation has been

performed, and the project is

proceeding to the next phase of

reservoir operations to extend

the duration of the full stage

reservoir operations. To capture

the necessary data to evaluate

the performance of the system,

GET developed and implemented

a monitoring and surveillance

program to evaluate downstream

groundwater levels and landslide

activity. GEl also performed

an inventory of the existing

instrumentation and groundwater

extraction network, and provided

recommendations for maintenance

and improvements.

darn sites), and a raw water

transmission pipeline. Cost

estimates included probable costs

for construction, engineering,

administration, legal, permitting,

land acquisition, and appropriate

Urban and Non-Urban Levee Evaluation Program California Department of Water Resources

The California Depart-

(DWR) is engaged in an

unprecedented effort to

comprehensively evalu-

ate 350 miles of urban

levees (i.e., levees that

protect at least 10,000

people) and 1,250 miles

of non-urban levees

(i.e., levees that protect

less than 10,000 people)

located within the Cen-

tral Valley.

The evaluations are being

performed through the Urban

Levee Evaluation (ULE) project

and the Non-Urban Levee

Evaluation (NULE) project,

respectively, using a multi-talented

consulting team of which GEl

Consultants, Inc. is a key member.

The evaluation of current system

performance is to include an

estimate of the risk of levee failure

by determining whether they

meet defined geotechnical criteria

and, where needed, identify

remedial measures, including cost

estimates, to meet those desired

geotechnical criteria. These

evaluations are being conducted

with the goal of providing 200-

year (0.5% chance on any given

year) level of protection in urban

areas and the design profile level

of protection in non-urban (rural)

areas.

As an essential first step in

providing improved flood

protection for communities in

the Central Valley, geotechnical

exploration, testing, and analysis

of state and federal levees that

protect the highly populated

urban areas of greater Sacramento,

Stockton/Lathrop, and Marysville/

Yuba City are being performed.

(This program is being

implemented simultaneously with

various urgent levee repairs.)

To expedite flood control

efforts aimed at protecting these

communities, levee evaluations

are being conducted in a fast-

track manner over a two- to

three-year period. During

this time, the consulting team

members are reviewing existing

levee historical data; conducting

field explorations (including

drilling and geophysical methods,

along with associated laboratory

testing); performing engineering,

stability and seepage analyses;

and preparing preliminary design

and construction estimates for

repairing and upgrading the

levees, where needed.

Feather River Setback Levee Three Rivers Levee Improvement Authority (TRLTA), Yuba County, Calfbrnia

The Feather River

Setback Levee project

was developed and

implemented by TRLIA

to replace the existing

deficient levee with a

new setback levee that

will increase the level

of protection in South

Yuba County to a 200-

year flood event.

The project involved constructing

a new 6-mile-long levee that is

set back from the original levee

by up to one-half mile, opening

up approximately 1,600 acres

of additional land for expanded

floodway and ecological habitat.

GET consultants performed a

feasibility evaluation, geotechnical

investigations, preliminary and

final design of the setback levee,

and provided construction

management services. The

GEl team also secured the

required environmental permits;

provided support for right-of-

way acquisitions; and designed

a floodplain swale, the purpose

of which is to mitigate potential

fish stranding and increase

the frequency of floodplain

inundation to gain the associated

ecosystem benefits.

The project posed a significant

design challenge as the setback

levee had to be constructed

on a foundation composed of

highly-variable, soft and pervious

streambed deposits, and required

various methods of seepage

control to maintain integrity.

The project team performed

extensive geological and

geotechnical studies. The

geotechnical investigations were

used to refine the alignment of

the new levee and locate it on

an older, more consolidated soil

formation wherever possible. To

the extent practical, the levee was

located on an older soil formation

(called the Modesto Formation)

because this type of soil

formation has more strength, less

permeability, and less settlement

potential than the more recent

alluvial sediments found closer to

the river.

Ultimately, to control

underseepage, about five miles

of soil-bentonite slurry trench

cutoff wall (up to 75 ft. deep) was

constructed integral with the levee

structure, and 26 relief wells were

installed in areas where deep,

recent, alluvial soils could not he

avoided.

Construction of the levee

improvements took place between

June 2008 and November 2009.

The Feather River Setback Levee

and expanded floodway are now

fully operational and providing

the enhanced level of protection.

The Feather River setback levee

received the "2009 Flood control

Bear River Setback Levee Three Rivers Levee Improvement Authority, Yuba county, California

The Bear River Setback

Levee Project was

closely coordinated with

the U.S. Army Corps of

Engineers (USAGE) as it

is part of the Sacramento

Valley Flood Control

Project.

In 1997, levee failures on the Bear

and Feather rivers resulted in loss

of life and extensive property

damage within Reclamation

District 784 south of Marysville.

GEl worked closely with Yuba

County and RD 784 to investigate

regional solutions and local

projects that could mitigate future

flooding risks. One of the more

promising projects was a set-back

levee on the Bear River. The

existing levees provide flood

protection for approximately

16,000 acres of farms and urban

land within RD 784, including

40,000 current residents and 9,000

future households in the planned

residential development of Plumas

Lake. The 10,000-foot-long Bear

River Setback Levee gives the Bear

River additional channel capacity

and lowers the water surface

profile by about 3 feet during

major flood events.

GEl performed the feasibility

evaluation, subsurface

geotechnical investigations,

preliminary and final design of the

setback levee, slurry cutoff wall

and related features, and provided

construction management services

including QA/’QC. A unique

aspect of this design was the

degradation and reuse of the old

Bear River Levee. The GEl team

also designed environmental

restoration; enhancement measures

on 600 acres in the levee setback

area and floodway.

Project challenges included

designing and building the levee

on a foundation composed

of highly-variable soft and

pervious streambed deposits,

and meeting an accelerated

schedule demanded by the

California Reclamation Board and

USACE. GET performed fast-track

geotechnical investigations and

preliminary engineering, as well

as environmental permitting and

right-of-way acquisition.

To make the setback levee

available for the 2006-2007 flood

season, the design schedule was

compressed from 12 months to

9 months, and the construction

contract was divided into two

phases. Phase 1 completed the

2 mile, 60- 70-foot-deep slurry

wall and foundation preparation.

Phase 2 saw the completion of the

levee fill and related infrastructure.

Throughout the design and

construction process, GEl worked

closely with the Department of

Water Resources, the Reclamation

Board, USACE, and the Yuba-

Feather Work Group, a key project

proponent.

The Bear River Setback Levee

received the 2008 ASCE Flood

Control Project of the Year award.

F Io :i. Services

Slickrock Creek Dam Stauffer Management Companji (Astra Zeneca), Shasta Couny, California

GET provided engineering

services for the

investigations, design,

permitting, and construction

of Slickrock Creek Dam.

The 150-foot-high

embankment dam is a key

component of the $20-

million Slickrock Creek

Retention Reservoir (SCR-R)

for the Iron Mountain Mine

Superfund near Redding,

California.

GEl staff has provided engineering

services at the Iron Mountain Mine

Superfund site since 1994. Iron

Mountain Mine is an abandoned mine in

Northern California that contains

several inactive underground and open

pit mines, as well as numerous mine

tailings stockpiles. The mines and

tailings stockpiles discharge acidic

waters, typically with a high content of

heavy metals, which eventually reaches

the Sacramento River. The SCRR

collects acidic drainage from Slickrock

Creek and conveys it for treatment to an

onsite treatment plant.

Key activities performed by GET for the

SCRR project included:

Preparation of Design Criteria,

Geotechnical Data and

Geotechnical Design Reports.

. Preparation of Hydraulics Design

Report.

. Development of geotechnical

investigation and testing work

plans, supervision of testing

laboratories, evaluation of test

results and preparation of

recommendations.

. Preparation and review of

construction drawings and

specifications.

S Coordination and negotiations with

permitting and review agencies.

S Key to the project was the handling

of onsite mine tailings, some of

which contain elevated levels of

arsenic. The project plans approved

by the regulatory agencies included

incorporating mine tailings into the

SCRR dam embankment, and

onsite disposal of the remaining

tailings.

GEl personnel have provided additional

mine reclamation and closure support

for the owner at the Iron Mountain

Mine site since 1994. This work has

included a fall range of services, from

feasibility studies and conceptual designs

to site investigations, geotechnical

characterizations, detailed designs, cost

estimates, and construction oversight.

GET personnel have represented the

owner in meetings and negotiations with

the regulatory agencies and have

provided litigation support.

In December 2000 the Iron Mountain

Mine Project was successfully completed

when a global settlement agreement was

reached between the owner and the

EPA, and the owner turned over the

completed Slickrock Creek Dam design

to EPA. GEl provided engineering

support during the construction phase,

which was completed in 2004. The dam

has been operational for the last 8 years

and to date, GEl continues to provide

engineering support and to perform

annual inspections.

Eagle Mountain Pumped Storage Eagle Crest Energy Company

The Eagle Crest Energy

Company proposes to de-

velop the Eagle Mountain

Pumped Storage Project

near the town of Eagle

Mountain in Riverside

County, California

The Project will use off-peak energy

to pump water from the lower

reservoir to the upper reservoir

during periods of low electrical

demand and generate valuable peak

energy by passing the water from the

upper to the lower reservoir through

the generating units during periods

of high electrical demand.

The Project will be located entirely

off-stream in that neither the upper

nor lower reservoirs intercept a

surface water course. The project

reservoirs will be formed by filling

existing mining pits with water. The

mining pits are currently empty

and have been unused for decades.

Water to initially fill the reservoirs

and annual make-up water will be

pumped from groundwater within

the adjacent Chuckwalla Valley.

GET prepared the Federal Energy

Regulatory Commission (FERC)

filings for the licensing of the

Project. These filings included a Pre-

application Document and Draft and

Final License Applications.

GET’s responsibilities included

preparation of the Supporting

Design Report (Exhibit F of the

License Application) and the

Applicant Prepared Environmental

Impact Statement (Exhibit E of the

License Application), as well as all

other exhibits. In addition, GET

assisted the client with stakeholder

consultation. GEl provided technical

and strategic advice to the client on

a wide range of issues including the

FERC licensing process and potential

sources of water supply.

GET also is assisting the client with

the application for Section 401 Water

Quality Certification with the State

Water Resources Control Board; and

prepared an Applicant Prepared

Environmental Impact Report for

the State Board to comply with the

California Environmental Quality Act.

Technical evaluations included an

assessment of the potential impacts

of water supply pumping on the

local and regional aquifer; modeling

of seepage from the reservoirs using

SEEP 7W modeling; development of a

well system to monitor and recover

seepage using MODFLOW modeling;

plans for construction timing with

labor and equipment estimates;

preliminary design and cost estimates

of the water pipeline; and an erosion

control plan with best management

practices.
