April 18, 1995 State of Colorado Division of Mines and Geology 1313 Sherman Street Denver, CO 80203 RE: 112 ANNUAL FEE AND REPORT NARRATNE DOMTAR GYPSUM # 77-247 Domtar Gypsum's Coaldale tluany surtace mine operation penult #77-247 has been in Temporary Cessation Statis since August, 1990, In late 1990, app. thirty acres of affected land was graded, seeded and hydromulched. This reclamation work brought the total reclaimed acreage at the Coaldale Quany to 65 acres of the 100 total acres of affected land currently under permit. Additional seeding and straw mulching of the 1990 reclamation areas was performed during the 1992, 1993, and 1994 field seasons, as described in past years annual reports. The map aeeomplaning this report is for ease of locating these areas, although the acreages and specifically items 2 thru 6 on the report form have not changed. Field work at the site during 1994 included the reseeding of areas within the 1990 hydromulch areas that showed lack of vegetative establishment. App. ten acres of waste dump area as located on the map was reseeded with a native seed mi:lure listed in this report. In addition, two semi loads of clean wheat straw mulch was applied to the thirty acres of 1990 reclaimed ground at a rate of 2000 pounds per acre. This was the third application of straw mulch at this rate since the original aspen fiber hydromulch application in 1990. The entire 65 acres of reclaimed mined land was maintained as needed. This included some minor reseeding and mulching on the northern aspect of the South End Waste Dump and the removal of many wire cage/animal damage control devices that had been installed over tree seedlings In the past. Tumbleweeds and excess vegetation was removed from other wire cages. 1994 field work included a site investigation by DMG for the purposes of evaluating possible closure criteria should this option be pursued by Domtar in 1995. Domtar has until August 29, 1995, to declare their wish to 1) close the mine operation, 2) continue TC statis for five additional years, or 3) resume operations. Domtar has scheduled a strategic planning session for all of its field operations during June 1995 at which time this decision making process will be entertained in regards to the Coaldale site. During the summer of 1984, a task list of various components of closure criteria for the Coaldale site was sent to DMG including gross cost estimates for the various tasks necessary for aucceaful closure. Seven major areas of concern were outlined including a range of cost estimates depending the extent of backfilling, highwall removal, and topsoiling called for by DMG for the various areas involved in final closure. It is anticipated by the writer that the issue of site statis will be addressed during the summer of 1995. As soon as Domtar's decision is made, the appropriate coorespondence with DMG will be made. Also during 1994 and early 1995, a Stonnwater Management Plan for the site was reviewed and developed including a complete watershed modeling of the mine site and those areas above the mine site contributing to potential stonnwater flow. Afield investigation by a DMG hydrologist pointed out areas of concern and actions were taken at the site to address those concerns. A complete Stormwater Management Plan is currently being reviewed by DMG. New atone ditch and sediment pond construction was performed in
