• (Tech. Rev. 33) to reduce monitoring £requeacies at Site SSLGS and Spoil Spring <br />#1. NPDE9 Discharge Point 003 is monitored weekly for field parameters (£low, <br />temperature, DB, and electrical conductivity). Pointe 002, 004 and 008 are <br />monitored monthly for Field parameters. All four NPDE9 sites are monitored <br />monthly for NPDES parameters. Monitoring frequency chaIIgee for 002, 004, and <br />OOS went into of Fact oa September 1, 1999 (see "Introduction"). Stream <br />Monitoring Sites SSG1 and S3G2 are monitored for field parameters monthly from <br />March through October. Both of these sites, ae well as Sites SSG3 sad SSLGS, <br />are sampled three times a year for full-suite water quality. The fire[ sample <br />of the year ie collected during the spring runoff (March or April), the second <br />sample is collected after the spring runoff (May or .Tune), and the third sample <br />is collected Suring base flow conditions (September). Full-suite lnb samples <br />collected at all these eitee were aaalyze8 using the surface water long list, <br />Table S. The two stream sites on Fieh Creek (Sites SSF11 and 13), and the two <br />oa Fish Creak tributaries (Sites SSC10 an8 SsH12i, era monitored monthly from <br />May through September for field parameters and full-suite lab eamylee. Whoa ao <br />• flow ie observed at the Cow Cam or Boad Creak aitea (Sites 30 end 12), the two <br />Fieh Creak aitea (sites 11 and 13) are not monitored. <br />At the Seneca II Mina, there are eight spoil springs are monitored for field <br />parameters and Eull-suite lab samples in the gyring and fall seasons. Ia <br />addition, Spoils Spring 1 was sampled for a full-euite lab samples coneurreatly <br />with NPDES 004, sad was monitored monthly and concurrently with NPD89 004 for <br />field parameters from March to October. <br />Surface water quality data are presented is Appendix D. Data for each Bite <br />begins with a Flow hydrogreDh of ell historic data (plus an annual hydrograph <br />for NPDES eitea), followed by a listing of individual water quality and quantity <br />data for the current water year, a TDS regression plot using the LOWESS method <br />(nee Ground Water Quality aectioa), sad then a listing of historic percent <br />milliequivalent values for maior ions and TDS values. Crest stage gage rating <br />curves are presented is Appendix E. Lab samples are handled identically to <br />procedures diacuesefl previously in the Ground Water Quality section. <br />i~ <br />
