1. Topsoil Stockpiles - I have decided to designate two specific areas for stockpiling topsoil for the next few years. These are identified on the enclosed mining plan map and are located within the 4 acre, "future stockpile area." After a period of several years, the northernmost, topsoil stockpile would eventually be abandoned and could be moved into the area identified on map as "undisturbed". This move would occur several years after mining is initiated in the "undisturbed" area. A technical revision to our mining plan would then be requested at that time. This is identified on the map as future topsoil site, and is located along the western boundary of "undisturbed" permitted acreage. 2. Seeding of Topsoil Stockpiles - Mathias Concrete, Inc. would commit to the seeding of topsoil stockpiles that would be in place for more than one year. They will be seeded with Western Wheatgrass. 3. Seed Mix and Rates - Because of good availability and price, Mathias Concrete, Inc. would commit to the following seed mix and rates in the reclamation plan. Russian Wildrye (Vinall Variety) - 6 lbs./acre Western Wheatgrass (Arriba) - 8 lbs./acre Intermediate Wheatgrass (Oahe) - 6 lbs./acre Smooth Brome (Manchar) - 4 lbs./acre Blue Grama (Native) - 4 lbs./acre Cicer MilkMetch (Monarch) 2 lbs./acre 4. Water Used for Washing - The wash water used in our screening process is diverted from a concrete bin into a 30' x 40' settling pond. The fines are periodically removed (every other year) and are spread onto graded areas for seeding. The water percolates into the sand and gravel alluvium underneath. We applied for a NPDES permit for this operation in 1991 and have not received any response. It may be, that we do not need one for this small operation. 5. Fertilization - Because of the improved seed mixtures of drought-resistant grasses, and our successful rate of germination the last couple of years, I do not believe fertilization is necessary for successful reclamation. 6. Reclamation Cost Per Acre and Phased Operations - Initially, I had stated that the cost per acre for ma,~or disturbance would be 31890.00. I would like to revise this estimate based on designating specific topsoil, stockpile areas, and incorporating a scraper into the actual topsoiling process.
