Rule 4.05.13(4)(a) The data collected, including analytical results, shall be tabulated on a site by site basis and kept on file at the mine office for inspection by the Division. These data shall be submitted to the Division as required in 4.05.73(4)(c). The data, compiled in AHRs, is maintained at the Routt County Court House (the mine is in permanent cessation). See Rule 4.05.13(4)(c) below. Data as gathered needs to be kept on file, The operator is asked to start maintaining this information at the Court House. Rule 4.05.13(4)(b) Ground water and surface water data collection shall be based upon a water year (October 1 through September 30), unless otherwise approved by the Division. The report is in compliance with this rule. The Permit Application Package (PAP) calls for awater-year report (page 4.6-139). Cumulative data is presented through September 2004 (October 1, 2004). Rule 4.05.13(4)(c) A hydrologic report shall be submitted to the Division annually with the date of submittal determined in consultation tivith the permittee. The annual hydrologic report shall contain at a minimum.• The report is an annual report. It was due February 20, 2005 (PAP page 4.6-139), and was received at the Division on February 25, 2005. The schedule was brought to the attention of the operator. Rule 4.05.13(4)(c)(i) Water quantity data obtained from each monitoring site during the water year; The report is in compliance with this rule. See the table below. Rule 4.05.13(4)(c)(ii) Water gualiry data obtained from each monitoring site during the water year; and The report is in compliance with this rule, with the exception of a sample from the TCS-1 well, and that April monitoring results have not been reported since 1996 for some sites. See the table below. The data for this report is requested of the operator. A statement in the report indicates that the range of data was adequate to capture the peak runoff volumes in Trout Creek. Rule 4.05.13(4)(c)(iii) If required by the Division, a written interpretation of the data and identification of mining related impacts to the hydrologic balance. The Division has made no such requirement, but interpretations are presented. Trends in surface and ground water quality aze discussed, and there is a summary statement that all values for TDS are consistent with the probable hydrologic consequences projections (page 9 of the report). See the discussion below under Probable Hydrologic Consequences.
