PART I <br />Page No. 9 <br />Permit No. CO-0044776 <br />B. MOMTORING REQUIItEMENTS <br />1. Frequency and Sample Type (continued) <br />[f the permittee, using the approved analytical methods, monitors any parameter more frequently than required by <br />this permit, then the results of such monitoring shall be included in the calculation and reporting of the values <br />required in the Discharge Monitoring Report Form (DMRs) or other forms as required by the Division. Such <br />increased frequency shall also be indicated. <br />2. Salinity Parameters <br />In order to obtain an indication of the quantity of Salinity, measured as total dissolved solids (TDS) being discharged <br />from the site, the permittee shall monitor the wastewater effluent at the following frequencies: <br />utfa Frequency Sample Type <br />OOI, 002, 003 Quatterly Grab <br />Self-monitoring samples taken in compliance with the monitoring requires specified above shall be taken at those <br />locations listed in Part I.B.1. TDS shall be sampled on a monthly basis until six samples have been analyzed. A <br />report of "No Discharge" shall not be counted as one of the six samples. Thereafter, monitoring shall continue on a <br />quarterly basis. Following submittal of the initial six sets of montlily data, the Division shall determine whether the <br />permittee is required to submit a report addressing salt removal in accordance with Regulations For Implementation <br />of the Colorado River Salinity Standards (5 CCR 1002-39) . If the salinity report is required, the Division shall so <br />notify the permittee by letter or through the inclusion of a compliance schedule and the report shall be submitted <br />within 180 days of notification. <br />Where, based on a minitnum of 5 samples, the permittee demonstrates to the satisfaction of the Division that the <br />level of TDS in [he effluent can be calculated based upon the level of electrical conductivity, [he permittee may <br />measure and report TDS in terms of electrical conductivity. <br />C. DEFINITIONS OF TERMS <br />1. "Continuous" measurement, is a measurement obtained from an automatic recording device which continually <br />measures provides measurements. <br />2. "Daily Maximum limitation" means the limitation for this parameter shall be applied as an instantaneous maximum <br />(or, for pH or DO, instantaneous minimum) value. The instantaneous value is defined as the analytical result of any <br />individual sample. DMRs shall include the maximum (and/or minimum) of all instantaneous values within the <br />calendar month. Any instantaneous value beyond [he noted daily maximum limitation for the indicated parameter <br />shall be considered a violation of this permit. <br />3. "Grab" sample, is a single "dip and take" sample so as to be representative of the parameter being monitored. <br />4. "[n-situ" measurement is defined as a single reading, observation or measurement taken in the field at the point of <br />discharge sZ analyzed in the laboratory within a short period after collection, as specified by approved medtodology: <br />5. "Instantaneous" measurement is a single reading, observation, or measurement performed on site using existing <br />monitoring facilities. <br />6. "Quarterly measurement frequency" means samples may be collected at any time during the calendar quarter if a <br />continual discharge occurs. If the discharge is intermittent, [hen samples shall be collected during [he period that <br />discharge occurs. <br />
