4. Records <br />Arsenic 0.01 mg/Q <br />Benzene 0.001 mg/Q <br />Total Residual Chlorine 0.05 mg/Q <br />Cadmium 0.0003 mg/Q <br />Chromium 0.01 mg/Q <br />Chromium, Hexavalent 0.01 mg/Q <br />Copper 0.005 mg/Q <br />Lead 0.005 mg/Q <br />Total Mercury 0.00025 mg/Q <br />Nickel 0.05 mg/Q <br />Selenium 0.01 mg/Q <br />Silver 0.0002 mg/Q <br />Zinc 0.05 mg/9 <br />These limits apply to the total recoverable or the potentially dissolved fraction of metals. <br />The permittee shall establish and maintain records. Those records shall include the following: <br />5. Flow Measuring Device <br />Part I <br />Page No. 10 <br />Permit No.: CO- 0027529 <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 />For hexavalent chromium, samples must be unacidified so that dissolved concentrations will be measured rather than <br />potentially dissolved concentrations. Procedure for determining settleable solids is contained in 40 CFR 434.64. The method <br />detection limit for measuring settleable solids under this part shall be 0.4 m1/1. <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)(1)(iii) <br />The permittee 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 this 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 or EPA. <br />If not already a part of the permitted facility, within ninety (90) days after the effective date 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 in Part I.E.5 of this permit, a flow measuring device will be applicable at all designated <br />discharge points. <br />At the request of the Division, the permittee shall show proof of the accuracy of any flow - measuring device used in obtaining <br />data submitted in the monitoring report. The flow - measuring device must indicate values within ten (10) percent of the actual <br />flow being discharged from the facility. <br />
