I 1 � I 01 June 2011 AGE-NC Project No . 08- 1607 Page 2 of 3 • Annual : Collect ground water samples from ground water monitoring wells MWA through MW-3 and submit an annual report to include semi-annual ground water measurements . The first annual event should be performed in the third quarter of each year; • Biennially: Collect groundwater samples from monitoring wells MW-4through MWA 1 and MW- 12D ; and • Suspension of ground water monitoring from soil vapor extraction wells SV- 1 through SV-9 . Justification for reduction of ground water monitoring and reporting is based upon financial constraints , significant remediation performed at the site to date, a relatively stable plume, and no apparent sensitive receptor located within 1 , 000 feet of the site . The USTCF claim for the site has exceeded the $ 1 . 5 million cap and was used to removed a significant mass of petroleum hydrocarbons from the site . Historically , approximately 3, 872 , 897 gallons of ground water was extracted , treated and discharged under City of Stockton discharge permit, which resulted in removing a calculated 755 . 77 pounds of gasoline (TPH -g) from the dissolved phase. Additionally, approximately 10 , 145 .4 pounds of petroleum hydrocarbons was removed from the vapor phase through soil vapor extraction . A total of 10 , 901 . 17 pounds of petroleum hydrocarbons is calculated to have been removed from the site . In August 2001 , a sensitive receptor survey was conducted and no known operational domestic wells were found within 2 , 000 feet of the site; however, two operational municipal supply wells may still be in operation in the southwest corner of the Lincoln Center at Douglas Road and Gettysburg Place (over 1 , 000 feet to the east-northeast) . No other potential receptors appear to be located within 2 , 000 feet based upon the 2001 survey. Additional lines of evidence have been investigated and include compound specific isotopic analysis. After SJCEHD has an opportunity to review the report on the potential second release , which should be published by 30 June 2011 , AGE requests a meeting with SJCEHD to discuss the findings of the potential second release, monitoring and reporting requirements and an economically feasible plan for site closure. AGE requests a delay in the requirement to collect ground water samples from all site wells , which total 21 wells if the remediation wells are included , until after SJCEHD's review of the report on the potential second release . The annual ground water monitoring event is proposed for the third quarter of this year. AGE also requests further delay of submittal of a feasibility study and work plan , which were required by SJCEHD within 30 days of the 18 May 2011 letter, until after meeting with Advanced GcuEnvirnnmcntal, Inc.
