Parmar Texaco - 2 - 14 September 2023 <br /> Proposed monitoring well PT-MW10 will not be drilled until an encroachment <br /> permit is obtained from the City of Lodi (City). Please notify Staff when the City <br /> encroachment permit is received and provide a schedule for drilling this well at <br /> least two weeks prior to installation. <br /> ® Proposed borings PT-MW11 and PT-MW12 will not be drilled "until the new <br /> groundwater sampling results from the well network are obtained from the next <br /> groundwater monitoring and sampling event." Muir proposes to conduct a <br /> groundwater sampling event in November 2023. <br /> To reduce the cost of routine groundwater monitoring and reduce unnecessary work, <br /> Staff requests that you please reduce the frequency of groundwater monitoring events <br /> to a semiannual basis, with monitoring events occurring during the second and fourth <br /> quarters of each calendar year. Please report second quarter monitoring results by <br /> 1 August and fourth quarter monitoring results by 1 February. To clarify the monitoring <br /> schedule, please implement the following: <br /> o Semiannual: PT-MW-1, PT-MW-3, PT-MW-6, PT-MW-8, PT-MW-9, <br /> PT-SVE-1, PT-SVE-2 <br /> o Annual (fourth quarter only): PT-MW-7 <br /> o Semiannual (water level measurement only): PT-MW-2, PT-MW-4, <br /> PT-MW-5 <br /> By 24 November 2023, please complete the work proposed in the Workplan Memo and <br /> submit a detailed summary report. In this report, please evaluate site conditions against <br /> the State Water Board's UST Low-Threat Case Closure Policy criteria and propose a <br /> path forward to close this case, which may include additional investigation, remediation, <br /> or case closure. <br /> By 1 February 2024, please submit a semiannual monitoring report for the fourth <br /> quarter of 2023. <br />
