Kinder Morgan Energy Partners, Holt -3- 1 August 2000 Inspection Report MONITORING AND REPORTING REQUIREMENTS: Review of the quarterly self-monitoring report (SMR)for the First Quarter 2000 found a violation of the effluent limits during the January 2000 sampling event. The reported concentrations for both TPH-gasoline and TPH-Diesel exceeded the allowable 30-day median (50 µg/1) and daily maximum (100 µg/1) effluent limits. Benzene and xylenes exceeded the 30-day median effluent limit of 0.5 µg/l. These Group H Pollutants exceed the effluent limitations by more than twenty percent (20%) and are considered a significant violation as specified in California Water Code Section 13385 (h)(1) and (h)(2)• The NPDES sampling and analysis requirements are reiterated with the requirements for groundwater monitoring in revised Monitoring and Reporting Program(MRP)Order 94-806, issued 21 September 1999. I inspected the receiving water sample locations, R1 and R2. The Discharger is collecting samples of the receiving water at the designated locations required by the Order. The Discharger has submitted the SMRs by the due dates specified by the MRP. The information presented in the SMRs is consistent with that required by the Order and the MRP. BMUD aboveground aqueduct is located above :? Trapped air in treatment system reveals pproximate location of submerged outfall. Trapper Slough, receiving water. RWQCB SAMPLING AND ANALYSIS: To supplement the inspection,I collected influent, effluent and receiving water samples and submitted these samples for independent analytical testing. The samples were analyzed for the constituents required within the MRP. As part of the sample collection, I also conducted field screening for pH, electrical conductivity, and dissolved oxygen where possible. The results of the field screening are summarized in Table 1. The results of the independent analytical testing are summarized within Table 2. Tertiary butyl alcohol (TBA) (54 µg/1), hardness (480 mg/1), barium(180µg/1), and iron (4,300 µg/1) were reported in the effluent sample analyzed.
