Performance Work Statement

Pilot Work Study – Feasibility Study Report of Putah Creek Resort Gasoline Contamination - Lake Berryessa Concessions Area

1.0 Background

The site of study is a former underground storage tank (UST) at the former Putah Creek Resort located at Lake Berryessa (see Figure 1), which is part of The Bureau of Reclamation, Central California Area Office.

The street address for the site is former Putah Creek Resort, 7600 Knoxville Road, Napa, CA 94558.

A Concessionaire operated UST located at Putah Creek Resort discharged 760 gallons of unleaded gasoline in 1990. Groundwater depth ranges from 2 to 25 feet below the ground surface. Structural complexities and secondary permeability caused by fracturing of the rock appear to have a substantial influence on the movement of groundwater. Historic monitoring data indicates fracturing may have created preferential contaminant paths.

Petroleum contamination was first discovered in the soil around a leaking UST in May 1993. Two 8000 gallon UST’s were removed from the site on April 1995. Approximately 4,000 cubic yards of contaminated soil were removed from the sited down to a depth of 23 feet. Total petroleum hydrocarbons as gasoline (TPH-g) was detected in soil samples collected during the excavation as high as 2,300 mg/kg parts per million (ppm). Soil was stockpiled on site and aerated until confirmation samples indicated that TPH-g concentrations had reduced below 10 ppm. Monitoring wells were installed at the site during 1999-2001.

Initial monitoring wells detected TPH-g in the groundwater ranging up to 340,000 ug/L (ppb). An installation of an in-situ ozone sparging system was done in 2002. This system was operated until 2004. A groundwater treatment system was constructed pumping a rate between 4-7 gallons per minute (gpm) in 2004. The groundwater treatment system operated from April 2005- August 2008. The system was discontinued because the extraction rate had decreased to less than 1 gpm. The treatment system appeared to be ineffective due to minimal groundwater recharge due to drought conditions.

In 2009 the site was issued a Clean-up and Abatement Order R5-2009-0704 by Central Valley Regional Water Control Board (CVWQB).

From 2010 until 2012 a contract was issued to conduct a pilot study and feasibility report, several new wells were installed and some soil excavation occurred. Best choice technology was dual-phased extraction (DPE). Brief DPE implementation occurred but determined to not be a cost effective long term solution. A summary of the results of the DPE pilot study, treatment, and Human Health Risk Assessment (HHRA), is provided and a complete copy of the conclusions is available upon request (2011-2012 Dual Phase Extraction Pilot Test Study and Treatment report – Accord Engineering):

The Site is in a fractured and folded sedimentary rock environment with complex soil geology. Fractured-rock sites are among the most complex to remediate because of their considerable geologic heterogeneity and the nature of fluid flow and contaminant transport through fractured media. Groundwater restoration has proven to be difficult in complex hydrogeological environments such as in fractured-rock aquifer systems (U.S. EPA 2001). At this Site, dissolved-plume migration has not shown a fast transport pathway through the 12 years of groundwater monitoring. Contamination, especially aged and weathered TPH released more than two decades ago at the Site, is likely to be sequestered within the rock matrix or poorly connected small fractures, that are diffusion-limited and will require long remediation timeframes. Based on the results of the pilot study/treatment and HHRA, (2011-2012 Dual Phase Extraction Pilot Test Study and Treatment report – Accord Engineering) the selected remedy going forward proposes a continuation of long-term groundwater monitoring, with potential treatment if the site specific cleanup goals are not met.

A semiannual groundwater monitoring program was the selected remedy used to: (1) assess the effectiveness of biodegradation of Chemicals Of Primary Concern (COPC) - TPH-g, BTEX, and MTBE within the dissolved plume; (2) collect additional data over time to assess trends in concentrations and determine if additional action is required; and (3) target areas (if any) where additional treatment may be needed if an increase in COPC concentrations (i.e., rebound for TPH-g, BTEX, and MTBE) occurs or if natural attenuation is not sufficient to reduce COPC concentrations to cleanup goals. Semi-Annual groundwater monitoring has occurred since 2012 (data available upon request).

In CVWQB letter dated December 31, 2014 Reclamation agreed to conduct a Pilot Study at site, an effort to develop a cost effective remediation strategy is desired. The Bureau of Reclamation would like three (3) different technologies evaluated other than what has already been previously tested.

Examples of possible known technologies are: 1) in-situ bioremediation, 2) in-situ chemical oxidation and

3) vapor extraction.

2.0 Scope:

Unless otherwise expressly provided herein, the Contractor shall furnish all the contract management, planning, supervision, administration, personnel, materials, supplies, transportation, facilities and anything else necessary to complete the work and deliverables described in this Performance Work Statement

(PWS).

This PWS is the implementation of a pilot study plan to mitigate the environmental impacts in groundwater and soils found at the underground storage tank (UST) fuel spill contamination area at Putah Creek Resort located at Lake Berryessa (see Figure 1), which is part of The Bureau of Reclamation, Central California Area Office. The street address for the site is Putah Creek Resort, 7600 Knoxville Road, Napa, CA 94558.

This pilot study shall include an evaluation of at least three (3) different in-situ multimedia technologies that may be effective for treating both soil and groundwater at the site, and selecting the most feasible technology for a pilot test at the site to verify the effectiveness and implement ability.

Site-specific bench-scale tests will be used to facilitate the alternatives evaluation as part of the pilot study. Examples of possible known technologies are: 1) in-situ bioremediation, 2) in-situ chemical oxidation and 3) vapor extraction. If the pilot testing results are favorable, a Corrective Action Plan (CAP) with comprehensive cost estimate with anticipated timeline to closure shall be developed to address a full scale remediation at the site.

3.0 Objectives:

A renewed effort to develop a cost effective remediation strategy is desired at former Putah Creek UST site. Site has been characterized and profiled, using existing data and other as necessary the Bureau of Reclamation would like three (3) different technologies evaluated other than what has already been previously tested.

4.0 Tasks:

Task 1 - Develop Pilot Study Work Plan and Site Health and Safety Plan: The pilot study work plan shall include an evaluation of at least three (3) in-situ remedial technologies that may be effective treating the impacted soil and groundwater and soil at the site. Based on the evaluation results, bench-scale and pilot tests will be conducted using the most feasible technologies. The primary objective for this pilot study is to gather the site-specific data to evaluate the effectiveness and viability of an innovative in situ treatment technologies (i.e., three different methods at a minimum), to achieve physical mass removal and biological destruction of TPHg, BTEX and MTBe found in the groundwater and soil at Putah Creek site.

The pilot study will involve groundwater and soil treatment by 3 different technologies evaluating alternatives. The pilot study area will focus on the down gradient secondary source area near the shoreline around wells MW-14 and MW-16 or other deemed appropriate areas at the site, contamination site is characterized with defined plume (see Figure 2). A Pilot Study Work Plan will be prepared by the contractor to provide the detail and procedures to conduct the pilot study and performance monitoring to evaluate the effectiveness of the in-situ study.

The contractor will submit a Health and Safety Plan to include field safety requirements for the pilot study.

The Work Plan will be submitted in draft (for BOR internal review and approval), and final (for RWQCB) versions.

PERFORMANCE ASSESSMENT AND DISINCENTIVES

Monitoring Performance. During the course of the evaluation period, the COR/POC will track Contractor performance. Interim (mid-term) evaluations may be provided to identify strengths and weaknesses in the Contractor's performance during the period being evaluated. At the end of the period, the COR will assess the Contractor's performance in accordance with the Quality Assurance Surveillance Plan (QASP) and report to the Contracting Officer.

Contractor Self-Assessment. Following each evaluation period, the Contractor may provide a written self-assessment of its performance to the COR/POC to be considered in its report to the Contracting Officer. The self-assessment shall be submitted not later than 5 working days after the end of each evaluation period. The self-evaluation shall not exceed one page per PRS element. The self-assessment shall address both the strengths and weaknesses of the Contractor's performance during the evaluation period. Where deficiencies in performance are noted, the Contractor shall describe the actions planned or taken to correct such deficiencies and avoid their recurrence. The self-assessment itself will NOT be the basis for the Disincentives determination.

COR/POC Recommendation. The COR/POC will consider all evaluations and any other pertinent information, including Contractor self-assessment, and will prepare a report to the Contracting Officer with findings and recommendations. The Contractor will be provided a copy of the draft findings and recommendations of the COR/POC and will be afforded the opportunity to identify factual errors. The COR's draft recommendation is not subject to negotiation and the COR will not engage in discussions with the Contractor. Any errors identified by the Contractor will be addressed by the COR in its final report. The Contractor will be provided a copy of the final COR report at the same time the report is submitted to the Contracting Officer.

Payment Determination. The Contracting Officer may meet with the COR/POC to discuss the COR's report. The Contracting Officer will make a final determination in writing as to the percentage of work successfully completed, and the resulting payment to be made. A copy of the determination will be provided to the Contractor no later than 45 calendar days after the end of the period being evaluated. All Contracting Officer decisions regarding Disincentives are unilateral decisions made solely at the discretion of the Government.

Deduction. Notwithstanding any other clause of this contract, deduction of the Disincentive will be made within the later of 60 days after the end of the evaluation period or 30 days after receipt of an approved invoice.

The Quality Assurance Surveillance Plan (QASP) is one evaluation method the government uses to surveillance performance to determine whether the Contractor meets the standards of performance as defined in the PWS. The following performance requirements summary (PRS) will act as a QASP. The absence of a QASP for any contract requirement, however, shall not detract from its enforceability or limit the rights or remedies of the government under any other provision of the contract in determining the quality of the Contractor performance.

Performance Requirements Summary

The PRS chart (QASP) for each functional area of the contract requirement identifies the work requirement, contract reference, standard, method of surveillance, and work requirement weight. The Contractor’s performance of each contract requirement is evaluated on the basis of a number of performance elements such as Quality of Work, Quality Control, Scheduling, response, timely completion, and compliance with safety or labor standards. The applicable performance elements of each contract requirement are identified in the PRS.

The PRS chart:

Lists those requirements (column 1, Task and Critical Subtasks) which are required to be performed by the Contractor. The absence of any contract requirement from the PRS, however, shall not detract from its enforceability or limit the rights or remedies of the Government under any other clause of the contract.

Defines the standard of performance for each listed service (column 2, Quality Standards).

Sets forth the maximum allowable deviation (maximum error rate/acceptable quality level) from perfect performance for each listed service (column 3, Maximum Error Rate or Performance Requirement) that may occur before the Government will invoke the negative past performance evaluation.

Sets forth the primary surveillance methods the Government will use to evaluate the Contractor’s performance in meeting the contract requirements (column 4, Method of Surveillance).

Sets forth the Incentive and Disincentive that may occur when evaluating the Contractor’s performance in meeting the contract requirements (column 5, Incentive/Disincentive).
