40 f a Austin Road Landfill -4- 23 May 2000 Inspection Report COMPLIANCE WITH MONITORING AND REPORTING PROGRAM: Review of the SMRs found the Discharger, for the most part, to be in compliance with the monitoring and reporting requirements of the Order. However, quarterly SMRs are missing influent flow measurements. 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 all of the constituents required within the EIRP. As part of the sample collection, I also conducted field screening for pH, electrical conductivity, and dissolved oxygen. The results of the field screening are summarized in Table 1. The results of the independent analytical testing are summarized within Table 2. No exceedances of effluent limits were identified by the independent analyses. Chloromethane was detected but not quantifiable in the effluent and R-2 samples. Because chloromethane was not detected in the influent, this detection may be a laboratory artifact.
