Montrose County
Dear Mr Dillies
The following narrative is intended to address the adequacy concerns that were
detailed in your letter dated March 8, 1994 regarding the above referenced
Regular Operation (112) permit application.
Our response is submitted in the same sequence as presented in your letter.
1. A corrected copy of page 3 of the application form, which designates
the post-mining use as Rangeland, is included.
2. It is intended that a portable, drum mix asphalt batch plant be situated
at the site.
Materials that will be present on-site that have the potential Por a spill
are diesel fuel and asphalt cement. The diesel Puel tank has 10,000
gallons capacity and the asphalt tank has 20,000 gallons capacity.
The asphalt plant configuration requires an area that is 105 feet by 80
feet. A tertiary containment berm will be constructed around the
perimeter of the plant equipment. This berm will be 6" high and will be
constructed of compacted clay loam. This berm will have the capacity to
contain 31,400 gallons.
The drum mix plant will be placed on a 3" thick asphalt mat that will be
compacted to 95R density. Around the perimeter of this mat will be a
compacted clay loam berm 12" high.
Each oP the liquid material storage tanks will also be placed on a 3"
thick compacted asphalt mat and a 24" compacted clay loam berm will be
constructed around the perimeter of each mat.
