(Condor) on behalf of <br /> Triple E Produce Corporation (Triple E). This response has been prepared at the request of <br /> Triple E. We are pleased that you have found the overall Monitoring Plan meets the <br /> requirements of the Waste Discharge Requirements (WDRs) No. 96-118. <br /> in your letter, you asked Triple E to address some additional comments. Triple E has discussed <br /> these comments with us and on their behalf we provide the following responses. For clarity, <br /> the responses are numbered to correspond to the paragraphs found in the Monitoring Plan. <br /> 4.0 Sampling Program <br /> In the Monitoring Plan, Table 1 (page 3), entitled Parameters, Sample Type, Frequency, Method, <br /> and Sample Points, listed the proposed analytical or data gathering methods to be used for each <br /> monitored parameter. For Trihalomethanes, EPA Method 501/601 has been proposed. FGL <br /> Environmental, the analytical laboratory selected by Triple E, indicates that a recent directive <br /> from the federal EPA now advises the use of EPA Method 524.2. FGL Environmental has <br /> concurred with this advisory and is now using this method for TI-IMs including chloroform. <br /> Table 1 listed CCR Title 22 methodology for Standard Minerals. FGL Environmental is, <br /> however, using EPA Methods in the 100, 200, and 300 series depending on the individual <br /> constituent. The methods listed in Table l will be changed according to these recommendations <br /> since we rely on the expertise of the analytical laboratory staff in matters of appropriate <br /> analytical methodology. A copy of a revised Table I is included for your records. <br /> ENVIRONMENTAL 0 GEOLOGICAL 9 ENGINEERING 0 GEOTECHNICAL <br />
