Thus, the <br />discharge Elows should remain within this limit for the life of this permit. <br />Several analyses have been done for other metals at outfalls 003 and U22. The <br />analyses have shown that there was no need for additional limitations. The <br />water quality from No. 6 Mine is expected to be similar, thus no Further <br />monitoring or limitations are called Eor at this time. <br />Rased on monitoring results from October, 1985 to August 1986, it appears that <br />the discharges can meet the new limitations shown in Tab Le 1. <br />As a result of this amendment, pages la, ld, le, and if of the permit are <br />being amended. <br />Jon C.
