North County Recycling Center and Sanitary Landfill <br />Monitoring Implementation Plan <br /> <br /> <br /> <br />Page 9 <br />4.0 Sample Management <br />One grab sample of discharge from each outfall is collected for four discharges during the <br />reporting year as described in MIP Section 3.0. This section describes the management of the <br />samples after collection. Included in this section are sample preservation techniques, sample <br />storage, descriptions of the analyses and parameters to be analyzed, the appropriate analytical <br />methods to be used, required documentation, and the proper quality assurance/quality control <br />(QA/QC) procedures to follow. <br />4.1 Narrative Assessments <br />San Joaquin County annually reviews and evaluates its activities in light of the storm water <br />discharge observations and analytical data from each outfall. <br />4.1.1 Sampling Parameters <br />The General Permit in Section XI.B outlines storm water sampling parameters that are to <br />be analyzed. <br />The sampling parameters are to be analyzed using sufficiently sensitive test methods in <br />compliance with 40 CFR Part 136, or 40 CFR Chapter I, subchapters N and O in order “to <br />detect and quantify pollutants at or below the applicable water quality criteria, action <br />levels, or effluent limitations” for any applicable NPDES permit.19 <br />4.1.2 Universal Sampling Parameters <br />All storm water discharges are to be sampled for Total suspended solids (TSS), oil and <br />grease (O&G), and pH. <br />4.1.3 Facility-Specific Sampling Parameters <br />The General Permit requires in Section X.G.2.a.ii to assess “pollutants likely to be present <br />in industrial storm water discharges and authorized NSWDs.” Then in Section XI.B.6.c <br />the General Permit also requires that dischargers are to include in their monitoring <br />programs other parameters that are facility-specific (based on the General Permit Section <br />X.G.2.a.ii assessment) and are indicators of the presence of potential pollutants present in <br />storm water from the facility’s industrial pollutant sources. <br />In addition, the General Permit requires dischargers to include in their monitoring programs <br />other parameters that are facility-specific and are indicators of the presence of potential <br />pollutants present in storm water from the facility’s industrial pollutant sources. Since <br />paper and organic trash and debris are a common waste stream handled at this facility, the <br />facility will add Biological Oxygen Demand (BOD) and ammonia to its list of analytes. <br />Heavy metals aluminum, cadmium, copper, iron, lead, nickel and zinc are also potential <br />pollutants associated with both the waste transfer and landfill activities and the equipment <br />maintenance and are added to the list of analytes. <br /> <br /> <br />19 see 2018 Industrial Storm Water General Permit Amendment Fact Sheet at <br />https://www.waterboards.ca.gov/water_issues/programs/stormwater/docs/industrial/igp_factsheet_final.pdf or Amended General <br />Permit Section I.K.69
