NPDES Monitoring Requirement • 10 September 2OOi <br /> Attachment E-3 — Reporting Requirements <br /> 1. Laboratory Requirements. The laboratory analvzing the monitoring samples shall be certified b-, <br /> the Department of Health Services in accordance with the provisions of Water Code Section 131 i` <br /> and must include quality assurance/quality control data with their reports. <br /> ?. Criterion Quantitation Limit (COL). The criterion quantitation limits will be equal to or lower <br /> than the minimum levels (MLs) in Appendix 4 of the Policy;or Implementation of Torics <br /> Standards for Inland Surface Maters, Enclosed Bays, and Estuaries of"California (Copies of the <br /> SIP may be obtained from 'lie State Water Resources Control Board, or downloaded f orn <br /> httD:,'/www.swrcb.ca.gov/isw-o/final ndfl or the detection li_-.ts for purposes of:epos-g (DLRs) <br /> published by the Department of Health Services <br /> (htt ://vvww.dhs.ca_goy%ns:'ddwem/chemicals/DLR!dlrindex:htm) which is below the controlling <br /> water quality criterion concentrations summarized in attachment II of this letter. V <br /> 3. Method Detection Limit ( IDU The method detection limit for the laborato::shall be <br /> determined by the procedure found in 40 Code of Federal Regulations (CFR) Part 136, Appendix <br /> (revised as of May 14, 1999). <br /> 4. Reporting Limit(RLI. The reporting limit for the laborato7v. This is the lower, quantifiable <br /> concentration that the laboratory can determine. Ideally, the RL should be equal to or lower than <br /> the CQL to meet the purposes of this monitoring. <br /> 5. Reporting Protocols. The results of analytical determinations for the presence of chemical <br /> constituents in a sample shall use the following reporting protocols: <br /> a. Sample results greater than or equal to the reported RL shall be reported as measured by the <br /> laboratory(i.e., the measured chemical concentration in tre sample). <br /> b. Sample results less than the report RL, but greater than or equal to the labora.ory's NIDL, shall <br /> be reported as "Detected, but Not Quantified," or DNQ. :he estimated che`cal concentration_ <br /> of the sample shall also be reported. <br /> c. For the purposes of data collection, the laboratory shall write the estimated chemical <br /> concentration next to DNQ as well as the words "Estimated Concentration"(may be shortened <br /> to "Est. Conc.'s. The laboratory, if such information is available, may include numerical <br /> estimates of the data quantity for the reported result. Numerical estimates of data quality may <br /> be percent accuracy(= a percentage of the reported value), numerical ranges ow to high), or <br /> any other means considered appropriate by the laboraton.. <br /> d. Sample results that are less than the laboratory's MDL shall be reported as `Not Detected" or <br /> ND. <br /> 6. Data Format. The monitoring report shall contain the following information for each pollutant: <br /> a. The name of the constituent. <br /> b. Sampling location. <br /> c. The date the sample was collected. <br /> d. The time the sample was collected. <br /> 1 of3 <br />
