DISCUSSION
PCE Groundwater Cleanup - History and Past Actions:
On September 22, 2008, the City Council approved a settlement and cleanup agreement with the California Regional Water Quality Control Board (Board) for the City’s PCE (tetrachloroethylene) groundwater project. Under the agreement, the City agreed to commit $250,000 annually to fund work specified in a mutually approved Action Plan. The Action Plan includes provisions for an annual work plan that generally includes tasks to be completed by the City for each following fiscal year.
The Council approved an Agreement for Professional Services with Provost and Pritchard Engineering Group, Inc., at its July 5, 2016, meeting.
Current Site Status:
• One Hour Martinizing, 2828 G Street- The Board issued closure for the site on April 22, 2015. The site’s wells have been destroyed and the treatment system trailer transferred to the Sunshine site. This is the first of the seven sites to receive complete closure for the groundwater cleanup.
Status of the remaining PCE Sites (6):
• Former Sunshine Cleaners, 1227 W. Main Street- The treatment system trailer formerly located at the above G Street site was transferred to the Sunshine site to initiate soil vapor extraction to remove PCE vapors. The system continues to operate.
• Former Parkway Cleaners, 1530 Yosemite Parkway- A groundwater cleanup system is in operation. The system consists of air injection into groundwater with soil vapor extraction to remove PCE vapors. Although groundwater cleanup is occurring, it is progressing slowly. The prolonged drought has resulted in dropping groundwater levels that hampers cleanup efforts. This is because the existing injection wells are now above the water table and unable to inject air into the water. Soil vapor extraction continues.
• One Hour Martinizing, 1818 R Street- Staff requested closure for PCE impacts to soils at the site and the Board agreed in 2015. Groundwater monitoring only is occurring, and further action is deferred in accordance with the Settlement Agreement priority list.
• Former Simpson’s Dry Cleaners, 618 W. Main Street- The Board granted closure for PCE in soils at this parcel and concurred that the property may be developed. The Board has not issued closure for PCE in groundwater. Groundwater monitoring only is occurring and further action is deferred in accordance with the Settlement Agreement priority list.
• Former Bel Air Cleaners, 950 W. Main Street- Groundwater monitoring only is occurring, further action is deferred in accordance with the Settlement Agreement priority list.
• Merced Laundry, 160 W. Main Street- Groundwater monitoring only is occurring, further action is deferred in accordance with the Settlement Agreement.
The new Provost and Pritchard Engineering Group, Inc., $210,000 contract under consideration includes the following major tasks for fiscal year 2017 - 2018:
Former Parkway Cleaners
• Operation and maintenance costs of the treatment system;
• Carbon filter media replacement;
• Install three new deep monitoring wells;
• Deepen one existing monitoring well;
• System evaluation report.
Former Sunshine Cleaners
• Operation and maintenance costs of the treatment system;
• Carbon filter media replacement;
• System evaluation report.
The balance of the project annual $250,000 PCE cleanup funding commitment will be used to pay Board oversight fees for fiscal year 2017-2018.
PCE Reporting - History and Past Actions:
This Agreement for Professional Services is for consultant services to prepare quarterly monitoring reports on the status of PCE in groundwater in the City. The reports are necessary to demonstrate that the City is completing its obligations under agreements with the Board. The quarterly reporting task changes over time with added complexity as the PCE groundwater cleanup project advances.
The Council approved an Agreement for Professional Services for report drafting with Provost and Pritchard Engineering Group, Inc., at its July 5, 2016, meeting. This contract amendment is for Quarterly Monitoring Reports for the last two quarters of 2017 and the first two quarters of 2018 (fiscal year 2017/2018) at a cost of $58,500. Provost and Pritchard Engineering Group, Inc. has provided satisfactory service for the PCE project.
IMPACT ON CITY RESOURCES
PCE Cleanup Contract:
