RE: Amendment No. 2 to the Sunlight Coal Mine Reclamation Project, PKA-0-1071
Thank you for your interest in the Pre-Bid Meeting. The following clarifications and amendments
should be noted and incorporated into the bid documents:
1. The bid opening date is July 22, 1999 at 2:30 p.m.
2. The Time of Completion will be fourteen (14) calendar days. The project must be
completed prior to October 8, 1999 in nor more than fourteen (14) consecutive working
days. CONTRACTOR and PROJECT MANAGER shall mutually agree upon the start date
of construction in order to ensure that the project is completed by no later than October 8,
1999.
3. During construction, it will be necessary to cross the drainage swale located immediately in
front (south) of the collapsed mine entry. Upon completion of construction, the swale must
be returned to its original, pre-construction condition.
4. Topsoil to cover the coal refuse may be generated either by salvaging the soil currently in
place at the disposal area, or by pushing dirt from the hill immediately to the east of the
disposal area over the coal waste. A minimum cover of eight inches (8") of soil material
must be placed over all of the coal waste material. If material is excavated from the hill to
the east, the excavated area must not be of a lesser elevation than the coal waste
material. All trees and shrubs must be removed from within the footprint of the disposal
area prior to placement of the coal waste material. Upon completion of topsoil application
operations, the excavated hill to the east, if disturbed, must be graded so that the
topography matches and blends with the adjacent landforms. The excavated area will be
ripped to minimize soil compaction. The area will be roughened (see Task 2, Topsoil
Salvage and Surface Roughening), and revegetated (Task 4, Revegetation) per
specifications.
5. Note that at the coal waste disposal area and at the hillside to the east, if disturbed, weed
free straw mulch will be applied to the surface of the topsoil immediately upon completion
of topsoil application operations. Severe surface roughening, as described ion Task 2,
Topsoil Salvage and Surface Roughening, will occur simultaneously with the mulch
application so that the mulch is thoroughly incorporated into the soil. Mulch application
