To make this case, the prospector must provide historic water quality analyses, in the form of complete <br />copies of original laboratory reports, not summaries or handwritten notes. They should represent a series <br />of quarters when the mine was inactive. The report should include a request to reduce the required five <br />quarters of current baseline sampling based on a comparison (such as spreadsheets) prepared by the <br />prospector or agent, demonstrating that the past data are adequate to use in setting baseline parameters, <br />and are consistent with analyses from recently collected samples.. Good descriptions of the former <br />sampling locations and dates must also be provided. <br />If the Division agrees that the prospector has demonstrated that the analyses and the prepared <br />comparisons sufficiently verify that the current water quality and quantity is consistent with that from the <br />appropriate reports from previous sampling operations, and can therefore serve as substitute for some of <br />the currently required baseline sampling„ then the Division may reduce the requirement for current <br />sampling. <br />As always, your responses may be submitted in electronic form, but must be followed by submitting two <br />sets of hard copies of all materials. You may direct all submittals or questions to me at the Division's <br />Durango Field Office: 691 CR 233, Room A -2, Durango, CO 81301; telephone 970 - 247 -5193. <br />Sincerely, <br />i' Ai / <br />Bob Oswald l ' <br />Environmental Protection Specialist <br />Ec: Steve Shuey, DRMS Grand Junction <br />Cc: Greg Lewicki, Greg Lewicki and Associates, PLLC, 11541 Warrington Court, Parker, CO 80138 <br />(c: \1 1 -12 does \Revenue NOI_WQreq /rco) <br />
