`J -4- The actual quarry operation is still being conducted in acco[dance with the recommenda- tions of THK Associates. The 20' berm on the east has been reseeded and improved. The original purpose of the berm remains the same--to screen the quarry operations from being highly visible from populated areas. Shale material was hauled as an extension of the 20' berm area in 1986. This screening berm progression will be topsoiled and seeded. The floor of the quarry continues to be graded and maintained at all times so that runoff drainage is directed toward the southwest corner of the site where a detention pond gathers all runoff. The three previously constructed detention storage ponds are in daily use for recycling dust suppression water and collection of fine particle settlement. The ponds are at an average depth greater than the 4' specified and are provided with proper outlets. These ponds are cleaned during the winter and contents incorporated into the topsoil and used for seeding purposes. Asphalt Paving Co, continues to give asssurance that Che mining will continue in stages and is in compliance with the THK Associates and the Asphalt Paving Co. ap- plication to the Jefferson County Board of Adjustments concerning its mining operations over the life of the mine. Asphalt Paving Co. continues to make improvements and to upgrade tiie system. We are committed to providing a quality operation and a safe work place. Reclamation continues to be accomplished as per [he recommendations of 'fI1K Associates and will continue per the stages included and submitted with the plan. '1'lie crested wheat grasses, along with blue gamma and rye grasses, are rolled rind compacted into the soil after seeding to insure limited wind loss. On-site reclamation is being expanded in an ever-widening semi-circle as mining is completed. Reclamation signs have been installed to alert all incoming visitors that reclamation is an important part of our activity. Inasmuch as the quarry operation has not ceased operations, [he remaining flat benches have not been addressed in this report. A performance bond continues to be provided to the Colorado Plined Land Reclamation Board as well as Jefferson County in the monetary amount defined by tl~e land Reclama- tion Board and is consistent with their normal and accepted schedule of fees. A public liability and property damage umbrella insurance policy in the amount of $2 million has been kept in full force. Asphalt Paving Co. agrees to actively pursue an operating policy that continually tries to operate within all applicable rules, regulations and statutes of any county, state or federal agency having jurisdiction over any aspect of the operation. Water spray bars continue to be in operation and are installed at dust producing points in the crusi~ing operation, lJater trucks continue to spray the stockpiles, the stockpile areas and the quarry floor as well as those areas wlricli have been revegetated.
