PART I <br />Page No. 29 <br />Permit No.: CO-0000213 <br />E. GENERAL MONITORING, SAMPLING AND REPORTING REQUIItEMENTS <br />1. Routine Reporting of Data <br />Reporting of the data gathered in compliance with Part I.B.1 shall be on a monthly basis. Reporting of all data gathered shall <br />comply with the requirements of Part I.E. (General Requirements). Monitoring results shall be summarized for each calendar <br />month and reported on Division approved discharge monitoring report (DMR) forms (EPA form 3320-1). One form shall be <br />mailed to the Water Quality Control Division, as indicated below, so that the DMR is received no later than the 28th day of <br />the following month (for example, the DMR for the first calendar quarter must be received by the Division by April 28th). If <br />no dischazge occurs during the reporting period, "No Discharge" shall be reported. <br />The DMR forms consist of four pages -the top "original" copy, and three attached no-carbon-required copies. After the <br />DMR form has been filled out and signed, the four copies must be separated and distributed as follows: <br />The first original signed copy of each discharge monitoring report (DMR) shall be submitted to the Division at the following <br />address: <br />Colorado Department of Public Health and Environment <br />Water Quality Control Division <br />WQCD-P-BZ <br />4300 Cherry Creek Drive South <br />Denver, Colorado 80246-1530 <br />Additional copies are for the pemuttee records. The Discharge Monitoring Report forms shall be filled out accurately and <br />completely in accordance with requirements of this permit and the instructions on the forms. They shall be signed by an <br />authorized person as identified in Part I.E.6. <br />Calculations for all limitations which require the averaging of measurements shall utilize an arithmetic mean unless otherwise <br />specified by the Division in the permit <br />2. Representative Sampling <br />Samples and measurements taken as required herein shall be representative of the volume and nature of the monitored <br />discharge. All samples shall be taken at the monitoring points specified in [his permit and, unless otherwise specified, <br />before the effluent joins or is diluted by any other wastestream, body of water, or substance. Monitoring points shall not <br />be changed without notification to and approval by the Division. <br />If the permittee monitors at the point of discharge any pollutant limited by the permit more frequently than required by <br />the permit, using approved test procedures or as specified in the permit, the result of this monitoring shall be included in <br />the calculation and reporting of data to the Division. <br />3. Analvtical and Sampling Methods for Monitoring <br />The permittee shall install, calibrate, use and maintain monitoring methods and equipment, including biological and <br />indicated pollutant monitoring methods. All sampling shall be performed by the permittee according to specified methods <br />in 40 C.F.R. Part 136; methods approved by EPA pursuant to 40 C.F.R. Part 136; or methods approved by the Division, <br />in the absence of a method specified in or approved pursuant to 40 C.F.R. part 136. The analytical method selected for <br />a parameter shall be the one that can measure the lowest detected limit for that parameter unless the permit <br />limitation or stream standard for those parameters not limited, is within the testing range of another approved <br />method. When requested in writing, the Division may approve an alternative analytical procedure or any significant <br />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 <br />considered as violations of the permit limit. The present lowest method detection limits for specific parameters (which <br />have limitations that are, in some cases, less than or equal to the detection limit) are as follows: <br />Attachment 2.05.3(3)-18-33 <br />
