STATEMENT OF WORK

ENVIRONMENTAL RESPONSE CONTRACT

FOR

MICHELL FIELD, ME (FORMERLY DEFENSE FUEL SUPPORT POINT (DFSP) CASCO BAY)

BACKGROUND: The Defense Energy Support Center (DESC) administers military fuel storage and transportation facilities known as Defense Fuel Support Points (DFSPs). Mitchell Field, formerly known as DFSP Casco Bay (in the Town of

Harpswell, ME) is no longer an active facility and has been remediated to levels acceptable for recreational use.

SCOPE: The environmental service contractor shall conduct Long Term Monitoring in accordance with the Long Term

Monitoring Plan Groundwater Quality Monitoring Program for the facility. In addition the environmental services contractor shall also be capable of conducting Environmental Assessments and Environmental Remediations. Based on previous experience, DESC has compiled a list of services that might be needed to respond to an environmental work requirement.

Additional control, assessment, or remediation techniques recommended by the contractor may be approved for use on a specific response if the contractor can satisfactorily demonstrate to DESC that the techniques are viable for controlling fuel contamination, cost effective, available "off-the-shelf", and are acceptable to state and federal authorities.

The three known major categories of work to be provided under this contract are:

a. Water Level Measurements

b. Groundwater quality monitoring of Mitchell Field and nearby residential wells

c. Preparation of data reports

The following includes all tasks that the contractor must demonstrate a proficient capability to perform. However it should be noted that performance of most of these tasks are highly unlikely to be required during the term of the contract:

a. ASSESSMENT: During the assessment phase of work the contractor shall evaluate the lateral and vertical extent of contaminants in the subsurface, assess the nature and extent of free product that may be present, initiate free product recovery, assess the nature and lateral extent of groundwater and soil contamination, evaluate the geologic and hydrogeologic characteristics of the subsurface, and initiate a risk assessment. The Risk Assessment shall provide sufficient information to be used in Remedial Action Plan.

Typical Activities:

Conduct soil and groundwater sampling utilizing conventional boring or direct push technology, classification and analysis

(field screening, soil/gas survey).

Install observation and monitoring wells.

Perform soil and groundwater analyses.

Perform free fuel sampling and analyses including forensic testing.

Determine free fuel plume size and mass.

Determine dissolved fuel plume size and mass.

Perform pump test and analyze data.

Estimate the hydraulic conductivity (grain size, uniformity coefficient of the sediments, and porosity measurements).

Initiate interim free product recovery.

Prepare summary reports of activities.

Present findings to DESC representatives, regulatory agencies, and the public.

Conduct a risk assessment.

Conduct treatability testing.

Develop a Remedial Action Plan.

b. REMEDIATION: During the remediation phase of work the contractor shall install a fully functional, safe and reliable remediation system to cleanup the site. The contractor shall conduct concurrent engineering rather then sequential engineering. System development documents shall be produced to industry standards. System drawings shall be created with components which could be site adapted for use on future remediation projects. The contractor is encouraged to use “cut and paste” from previously used systems in order to minimize the effort and cost to develop a remediation system. Prepared system documents shall include text to advance the project into the next stage so that documents can be used “as-is” to procure the system without procurement specs.

Typical Activities:

Develop system drawings.

Obtain Regulatory Agency approval.

Procure system components.

Construct the remediation system.

Prepare O&M manual.

Perform start up.

Operate and maintain the system.

TASK 1. WORK PLAN. The Contractor shall develop a work plan to conduct an environmental site investigation or implement remediation at the site. The purpose of the plan is to list required tasks for a specific site assessment and/or remediation, and shall be in sufficient detail to obtain regulatory approval as well as initiate construction of the remediation system. The plan shall be developed under the direct supervision of a registered geologist, with extensive verifiable experience in hydrogeology in the State in which the work is to be performed. Upon approval of the work plan by the Contracting Officer and subject to the approval of the State or local regulatory agencies, the Contractor will implement the work plan. Proposals shall be based on the assumption that 30 work hours will be required to prepare a completed work plan. The proposal shall include providing and distributing a total of five (5) copies of the Work Plan. Upon final approval of the Work Plan by regulatory agencies, the Contractor shall provide the Contracting Officer a record copy on CD-R media of the approved work plan and all correspondence associated with the development and approval of the work plan (e.g. transmittal letters, regulatory agency correspondence, approvals, etc.).

TASK 2. SOIL BORINGS. The Contractor shall install borings using a hollow stem auger. Take soil samples every 5 feet or whenever a soil change is detected, employing a split spoon sampler. Samples shall be screened by head space analysis using an

Organic Vapor Analyzer (OVA) or equal. Drilling equipment shall be steam cleaned before installation of each boring. A certified geologist or hydrogeologist, working under the direct supervision of a registered geologist, shall be on-site throughout the drilling phase to classify soil conditions encountered, oversee boring installation, prepare boring logs, and monitor grouting of borings. Soil produced in drilling of borings shall be screened, and contaminated soil shall be placed on and covered with PVC sheeting. Non-contaminated soil shall be spread in the vicinity of the work. Disposal of contaminated soil will be authorized under Task 10 and/or 11. Soil handling procedures outlined under this Task are also applicable to all other Tasks where potentially contaminated soil is generated in the form of cuttings or excavation. Analytical laboratory testing of soil samples obtained will be ordered under Task 5.

TASK 3. MONITORING WELLS. The Contractor shall install 2" or 4" monitoring wells, as ordered. The monitoring wells shall be installed in accordance with procedures accepted by the State in which work is performed and the USEPA. Drilling equipment shall be steam cleaned before each use. Samples shall be collected using a clean split spoon every 5 feet or whenever a soil change is detected. The headspace of all soil samples shall be analyzed for volatile organic vapors using an OVA or equal.

Each well shall be developed to restore the natural permeability of the surrounding formation adjacent to the borehole, and until the water removed is sand free. Water produced in well development shall be collected in drums. Non-contaminated water shall be disposed of on-site in the vicinity of the work. Disposal of contaminated water will be authorized under Tasks 10 and/or 11.

The work shall include obtaining one water sample from the well after development, but analytical testing shall be ordered under

Task 5. Water handling procedures outlined under this Task shall also be applicable for all other Tasks where water is produced with the exception of Task 12. Well construction shall be performed by personnel who are qualified in the locality in which the work is performed. A certified geologist or a hydrogeologist, working under the direct supervision of a registered geologist, shall be present as required in Task 2. Abandonment of existing monitoring wells may also be ordered under this Task. Abandonment shall be conducted in full compliance with applicable regulatory agency requirements.

TASK 4. DIRECT PUSH TESTING. The Contractor shall use direct push testing procedures for screening or obtaining groundwater and soil samples for analytical testing. One soil sample and one water sample shall be collected from each probe location. Soil samples shall be screened by head space analysis using an OVA. Test probes shall be steam cleaned or otherwise effectively decontaminated after each use. The work includes grouting of bore holes in accordance with regulatory agency procedures. A certified geologist or hydrogeologist, working under the direct supervision of a registered geologist, shall be on site throughout the work to prepare logs and monitor grouting. One unit of direct push testing equals one day of on-site work.

Assume a maximum probe depth of 50 feet.

TASK 5. SAMPLE TESTING. Soil Samples collected under Task 2, 3, and 4 and Groundwater Samples collected under Tasks

3 and 4 shall be tested utilizing the test methods listed below. The types and number of tests to be performed for all Tasks will be determined at the time the work is ordered. In addition to providing “hard copies” of all analytical results, electronic deliverables of results must also be included in the price. The Offeror shall provide the turnaround time (business days) to obtain results and surcharges for 72 hour and 24 hour expedited turnaround.
