Please submit the report by 1 October 2023. <br /> Additionally, after re-review of your 17 February 2023 work plan, and my 18 April 2023 response, I wanted to clarify my <br /> concurrence with the proposed well destructions. I concur with the destruction of wells DMW-6, MWW-8, and DMW-15. <br /> However, I do not concur with destruction of well AMW-5, as it is currently impacted and has contained benzene greater <br /> than the LTCP Groundwater Class 4 threshold within the last 3 years. However,you may reduce the monitoring and <br /> sampling frequency of AMW-5 to annual. <br /> AL2vi, M. g�tehLer, P.G. <br /> Engineering Geologist I UST Enforcement Unit <br /> Central Valley Regional Water Quality Control Board <br /> California Professional Geologist#9340 <br /> 11020 Sun Center Drive, Suite 200, Rancho Cordova, CA 95670 <br /> Phone 916.464.4615 1 Fax 916.464.4704 <br /> a Ian.buehler@waterboards.ca.gov <br /> rn ir <br /> 0 a <br /> From: Hendricks, Brice<Brice.Hendricks@stantec.com> <br /> Sent: Friday,July 14, 2023 10:03 AM <br /> To: Buehler,Alan@Waterboards<Alan.Buehler@Waterboards.ca.gov> <br /> Cc: paul.anderson.ses<paul.anderson.ses@gmail.com> <br /> Subject: RE: DIRECTIVE LETTER-Stockton Charter Way Commingled Plume, Stockton (CP57) Extension Request <br /> EXTERNAL: <br /> Good morning, Alan, <br />
