Stipulation No. 17. The permittee will submit to the Division by January 30 of each year an <br />annual report which includes a summary of the previous calendar year's pit expansion, the <br />cumulative total number of acres stripped, acres reclaimed, and disturbed acres remaining to <br />be reclaimed. The report will also include a map showing actual reclaimed topography and a <br />report of backfilling mass balance calculations (Findings of Permit Renewal 2, 1992; Permit, <br />1986 (origin); Permit 1991). <br />Stipulation No. 23. In addition to the Laramie-Fox Hills monitoring well installed northeast of <br />the ash disposal cells, a monitoring well will be installed southwest of the ash disposal area. <br />All monitoring wells must be installed and functioning as designed prior to disposal of ash at <br />the mine site. Well location, design and construction techniques must be approved by the <br />Division prior to well construction. Frequency of monitoring for ash disposal monitoring <br />wells will be monthly, and parameters analyzed will include all parameters sampled for during <br />the Paste Extract Analysis of ash samples plus all parameters included in sampling of quarterly <br />water quality samples. [Findings of Permit Renewal 2, 1992; Permit, 1991; TR 13 (origin, not <br />verified)]. <br />Stipulation No. 24. Each year, a minimum of one (1) representative fly ash and one (1) <br />representative bottom ash sample shall be collected from the boilers at the Golden Power Plant. <br />Laboratory analysis of the samples will consist of Toxics Characteristic Leaching Procedure <br />tests (a replacement of the Saturation Extracts and E.P. Toxicity Tests -fer~aelrsample cited in <br />the Stipulation). Additional fly ash and bottom ash samples will be collected and analyzed if, <br />at any time, a source of coal is changed. Results of the tests <br />will be submitted to the Division within 15 days of permittee's receipt of analysis reports. <br />[Findings of Permit Renewal 2, 1992; Permit, 1991; TR 13 (origin, not verified)]. <br />Stipulation No. 25. An annual evaluation of ash disposal including, but not limited to, source <br />of ash, ash quality, total amount of ash disposed of, average depth of ash and aerial extent of <br />disposal areas, transportation and disposal techniques, water quality monitoring data, and <br />future ash disposal will be included in the Annual Hydrology and Reclamation Report. <br />Monthly reports consisting of source of ash, material quantities disposed of, depth of ash and <br />aerial extent, water quality monitoring data, and disposal problems (if any) will be kept at the <br />mine office and available for inspection [Findings of Permit Renewal 2, 1992; Permit, 1991; <br />TR 13 (origin, not verified)]. <br />Stipulation No. 26. Prior to resumption of coal extraction or associated surface disturbance at <br />the Keenesburg Mine, the permittee will obtain approval of a revision which will provide an <br />updated mining and reclamation schedule and which will demonstrate sufficiency of the <br />reclamation bond for the projected worst case disturbance during the permit term (Findings of <br />Permit Renewal 2, 1992; Mid-term review, 2/27/89 (origin, not verified). <br />3.1.5 Technical Revision (TR) <br />A review was accomplished of TR(s) processed since the March 17, 1992 Findings of <br />Compliance for a Permit Renewal (Permit Renewal 02).
