TCC conducted considerable additional data that was forwarded to the <br />Division for their use in review of TCC's 2000 Water Year AHR. The additional data <br />collection allowed TCC to effectively control mine discharge. <br />Additionally, the Division requested TCC to cross tabulated data for selected surface <br />sites and TCC provided this information. This was beyond what the permit or the <br />regulations required of TCC. This data compilation took an effort on the part of TCC, <br />with the end result of making the Division's job easier in its review of the AHR. <br />In regards to well 97-012TH, water pressure were obtained from the well. The recorded <br />water pressure was 2 PSI. This data provides information as to the stability of the <br />pressure in the unit. The hydrant will be repaired this spring so that higher pressures, if <br />they present, can be recorded. <br />If there are further clarification is needed, please contact me at your convenience. <br />Sincerely, ' <br />~~ ~~ <br />Richard Mills <br />Environmental Manager <br />File:I:\en\env\dmgWOV 2001-004response.doc <br />2e515 ROUTT COUNTY ROAD ~Y7, OAK CREEK, CO BW67 PHONE: (970) 879-3800 FA%: (070) 87&8050 <br />
