Joint Execution Team Meeting Notes <br /> Stallworth Auto Detail., 602 West California Street, Stockton <br /> CVRWQCB, Case # 390675 CUF Claim #12235 <br /> Teams Meeting November 27, 2023, at 10:00 am <br /> 1. Fund Status: CUF Amount Paid to Date: $842,360. Claimant recently hired a new <br /> consultant. <br /> 2. Discuss Low-Threat UST Case Closure Criteria Review. <br /> a. Groundwater Criteria — Not met. The length of the dissolved plume is greater <br /> than 100 feet in length and the dissolved concentration of benzene is greater <br /> than 3,000 micrograms per liter (pg/L). An additional downgradient B-zone <br /> monitoring well will be installed to determine current plume length and plume <br /> stability. MW-10 will be sampled during all future monitoring events. <br /> Consultant will get the access agreement from previous consultant and will <br /> contact the apartment complex owner to gain access to MW-10. MRP <br /> monitoring requirements will remain in effect due to increases in barium, TDS, <br /> and electrical conductivity in several wells including the upgradient <br /> background well. Consultant indicated that he believes that this is natural <br /> variability and will review the data and present a case to end the NOA <br /> monitoring. <br /> b. Vapor Intrusion to Indoor Air Criteria: Not met. Soil gas data are needed next <br /> to the building north of the former western UST that leaked most of the fuel <br /> that was released. A workplan for soil gas sampling will be submitted in <br /> December. <br /> c. Direct Contact and Outdoor Air Exposure Criteria — Not Met. Insufficient <br /> shallow soil data has been collected in the vicinity of the former UST to evaluate <br /> the criteria. A workplan for soil sampling will be submitted in December. <br /> d. General Criteria — Not Met. Unknown if secondary source has been removed. <br /> Will evaluate this criterion after the results of the next site investigation are <br /> available. <br /> 3. Wrap up <br /> a. Additional Items: <br /> b. Action Items: <br /> i. Consultant will get a phone number for the offsite apartment complex <br /> and gain access to sample MW-10. <br /> ii. Consultant will submit a workplan for monitoring well installation and <br /> onsite soil and soil gas sampling by the end of December. <br /> iii. Consultant will conduct a groundwater monitoring event including <br /> MRP sampling and hopefully MW-10 in early January. <br /> iv. Consultant will prepare a draft Project Execution Plan for FY <br /> 2023/2024. <br /> Attendees: <br /> ECAP Unit Staff— Scott Lookingbill Agency Unit Lead —Vera Fisher <br /> ECAP Unit Staff— Daniel Kramer Agency Senior— Galvin Kauffman <br /> Consultant— Greg Stahl Claimant— Nikey Stallworth <br />
