The item numbers in this response <br />correspond to those in the Division's letter. <br />1) PR-02 went into effect on December 10, 1999. Since the 1999 <br />AHR cover the water year (October 1, 1998 to September 30, 1999), <br />no data was collected at these surface water sites for the 1999 <br />water year. Monitoring at these sites (which was not required <br />until the effective date of PR-02) has been resumed in 2000 water <br />year. <br />2) Required monitoring at these four wells began on December <br />10, 1999 (see Item 1) Monitoring at these sites has been resumed <br />in 2000 water year. <br />3) Required monitoring at these two springs began on December <br />10, 1999 (see Ttem 1) Monitoring at these springs has been <br />resumed in 2000 water year. <br />4) SCC will revise the PHC as suggested in the upcoming permit ~_ <br />renewal application. <br />5) The Division is correct that there is no reference to the <br />EPA information (regarding the soil pH) in the CDPHE standard. <br />SCC provided this EPA information to justify our belief that the <br />state standard in inappropriately stringent in cases where soil <br />pH's are greater than 6.0. SCC will clarify this statement in <br />future AHR's. <br />Seneca Coal Company P.O. Drawer D Hayden, Colorado 81639 <br />Telephone (970) 276-3707 FAX (970) 276-3014 <br />
