RE: Central Shop, 1568 Broad Street Facility
Site Monitoring As a Corrective Action
Project File Reference: 88-057
OA TE: March 31,2000
Recently a Corrective Action Plan - Part A (CAP-Part A) addendum was submitted to Georgia
Environmental Protection Oivision(EPO) to address Underground Storage Tanks (UST) associated
contamination detected at the Central Shop Facility. "No Further Action Required" letter was
requested initially; however, EPO raised ~oncern about presence of residual contamination at the
site. As an alternative, semi-annual monitoring and reporting of groundwater for two years were
proposed as an interim corrective action. EPO approved the proposed alternative on February 11,
2000 and requested to submit timetable to complete the proposed activities. We proposed to perform
semi-annual sampling during the months of June 2000, December 2000, June 2001 and December
2001. Proposed Corrective Action is the cost-effective plan to comply with Federal and State UST
regulations. Change Order 2 will cover the cost to complete the activities proposed under CAP-Part
A. Environmental Site Assessment and CAP-PartA were completed by Envirorunental Management
Associates (EMA). Therefore, EMAwas contacted to submit a proposal to complete the proposed
additional activities. EMA personnel past involvement to address the groundwater quality
assessment issues at the Central Shop site and interaction with the EPO on our behalf will help to
addressEPO concerns (if any) with regard to residual contamination and also keep the proposed
work cost minimum.
Estim~ted cost to complete the additional

Dear Mr. Malik:
Re: Request for Proposal
Central Shop
Augusta, Georgia
EPD Facility 1.0. No. 9121077*1
Pursuant to our recent conversation, Environinental ManagemEmtAssociates(EMA) is pleased
to submit the following cost estimate to complete the proposed semi-annual groundwater
sampling and reporting requirements for the:abovereferenced facility (Facility). Our proposal
includes the costs associated with four semi-annual sampling events.
In accordance with the Corrective Action Plan - Part A (CAP-Part A) Responses dated
December 23, 1999, EMA has prepared a Monitor Only Plan that details the semi-annual
groundwater monitoring activities for two years (2000 and 2001). The Monitor Only Plan and
the estimated costs to complete this work are discussed in the following sections.
Monitor Only Plan
- -
The semi-annual groundwater monitoring events will consist of the sampling of seven existing
monitoring wells (MW-2, MW-3, MW-4, MW-5, IW-1, IW-3, and IW-6) for benzene, toluene,
ethylbenzene, and xylenes (BTEX) by SW-846 method 8021B. Monitoring well MW-1 will be
used to monitor the background concentrations. To demonstrate that natural attenuation is
occurring, EMA also recommends that these wells be measured in the field for dissolved
oxygen (D.O.), oxidation/reduction potential, and pH. Monitoring well MW-1 will be used to
monitor the background concentrations of the geochemical parameters.
The re~;utts of the sampling and analysis events will be reported to the Georgia Environmental
Protec:tio:hDivision (EPD) in a semi-aI)l1ualgroundwater monitoring report within 45 days of
the sa.mpling events. The reports will include a brief summary-of the Facility background, a
sumni.ary of findings that will include tabulated data and a potentiometric surface map, a site
ranking, and an evaluation to determine if a CAP-Part B will be required for this Facility "or if
the Facility qualifies for a "No Further Action" status.

If awarded the work, EMA will prepare the proposed milestone schedule for submittal to EPD
at no additional cost. EMA will also transport'the existing three drums of soil cuttings to the
Augusta-Richmond County Landfill at no additional cost. However, this does not include the
cost for disposal.
Estimated ecst
Based on the Scope of Work described above, EMA's estimated cost to complete these activities
on an annual basis is $4,750 ($9,500 for two years). A breakdown of the total cost is as follows:
Task
Total Cost
Groundwater Sampling/ Equipment
(2 sampling events)
$2,100
Analytical/Field Measurement Instruments
(7 samples per event/2 events)
$1000
Purged Water Disposal
$150
Report Preparation (2 reports)
Annual Total
$1,500
$4,750
TOT AL (x 2)
$9,500
EMA appreciates the opportunitY to submit this proposal to Augusta':Richmond-County.
Should you have any questions related to our proposal, please contact the undersigned at (770)
271-7098. We look forward to working with you on this project.
Yours truly,
