During this quarter, five NPDES outfalls were active. Outfalls 001 and <br />002 discharged routinely throughout the quarter. Outfalls 011, 020 and 021 discharged for a couple <br />weeks in March. Outfalls 003, 005, 006, 008, 009, 010, 012, 013, 014, 015, 016, 017, 018, 019, and 023 <br />did not discharge during the quarter. Outfalls 022 and 024 are associated with sediment ponds that have <br />not yet been constructed. No discharge is reported for these outfalls. Values reported on the enclosed <br />DMRs represent the maximum (or minimum as applicable) monthly/daily values generated at each <br />outfall during the quarter. <br />Also enclosed are monthly NOAH weather summaries for the reporting period, seep volume data for site <br />011, and WET test report forms as applicable. Outfalls 001, 002, 011 and 020 were sampled for WET <br />analyses during the applicable reporting period. Two species acute WET tests were completed at outfalls <br />001, 011 and 020 during the first quarter and a single species test (P. promelas) was completed at outfall <br />002. No exceedences of WET test limitations were observed at any outfall. Results of the outfall 002 <br />WET test will be reported with the next DMR submittal addressing the second quarter of 2002. No WET <br />test was completed for Outfall 021 because no pit water was discharged from this outfall during the first <br />quarter. <br />No exceedences of primary effluent limitations occurred during the quarter. Thank you for your <br />cooperation in this matter. Please contact me if you have any questions regarding the enclosed <br />information. <br />S'~Yi{n~cerely, ~ I <br />Frank .Self <br />Senior Environmental Specialist <br />FMSKms [c~ra~o;-aFa2 <br />~~ <br />7. a~+.
