/~ ~J,l?79 <br />1,...,,, 7/... C'O.uo~n ~a <br />F. GENERAL REQUIREMENTS <br />2. Analytical and Sampling Methods for Monitoring (continued) <br />The analytical method selected for a parameter shall be the one that can measure the lowest detected limit for that <br />parameter unless the permit limitation or stream standard for those parameters is within the testing range of another <br />approved method. When requested in writing, the Water Quality Control Division may z.pprove an alternative analytical <br />procedure or any significant modification to an approved procedure. <br />When the most sensitive analytical method which complies with this part, has a detection limit greater than or equal to the <br />permit limit, the permittee shall report "less than (the detectable limit)," as appropriate. Such reports shall not be considered <br />as violations of the permit limit. The present lowest method detection limits for specific parameters (which have limitations <br />which are, in some cases, less than or equal to the detection limit) are as follows: <br />Zinc 0.05 mg/~ <br />These limits apply to the total, total recoverable and the potentially dissolved fraction of metals. <br />Procedure for determining settleable solids is contained in 40 CFR 434.64. The method detection limit for measuring <br />settleable solids under [his part shall be 0.4 mL/0. <br />3. Records <br />The permittee shall establish and maintain records. Those records shall include the following: <br />a) The date, type, exact location, and time of sampling or measurements; <br />b) The individual(s) who performed the sampling or measurements; <br />c) The date(s) the analyses were performed; <br />d) The individual(s) who performed the analyses; <br />e) The analytical techniques or methods used; <br />F) The results of such analyses; and <br />g) Any other observations which may result in an impact on the quality or quantity of the discharge as indicated in 40 CFR <br />122.44 (i)(I)(iii). <br />The pertnittee shall retain for a minimum of three (3) years records of all monitoring information, including all original strip <br />chart recordings for continuous monitoring instrumentation, all calibration and maintenance records, copies of all reports <br />required by [his permit and records of all data used to complete the application for this permit. This period of retention shall <br />be extended during the course of any unresolved litigation regarding the discharge of pollutants by the permittee or when <br />requested by the Division. <br />4. Flow Measuring Device <br />If not already a part of the permitted facility, within ninety (90) days after the efTective da~•:e of the permit, a flow measuring <br />device shall be installed to give representative values of efFluent quantities at the respective discharge points. Unless <br />specifically exempted or modified elsewhere in this permit, a flow measuring device shall be applicable at all designated <br />discharge points. <br />At the request of the Water Quality Control Division, the permittee shall show proof of th~= accuracy of any Flow-measuring <br />device used in obtaining data submitted in the monitoring report. The Flow-measuring device must indicate values within ten <br />(10) percent of the actual flow being discharged from [he facility. <br /> <br />
