Permit Revisions
PR-02 proposed approval was issued December 5, 1997. The revision was submitted, in part,to address
deficiencies and inconsistencies identified in the Division's August 18, 1995 mid-term permit review,
and in part to organize the permit application package into a more useable format. The previous
permit application package was completely replaced by a new six volume permit application submitted
as PR-02. The format of the documents was completely reorganized, and significant and substantive
changes were incorporated in various sections of the application. The revision did not entail expansion
of disturbed, affected,or permitted acreage, beyond that previously set forth in the approved permit.
The Division's December 10, 1997, "Proposed Decision and Findings of Compliance for a Permit
Revision, Roadside North and South Portal Mines",was prepared pursuant to PR-02.
Technical Revisions
TR-16 proposed approval was issued January 4, 1994. The revision allowed for a reduced cover depth on
approved coal processing waste disposal areas, and addressed details regarding reclamation sequence, soil
handling, and vegetation monitoring on final reclaimed areas.
TR-17 proposed approval was issued April 19, 1994. The revision established two borrow areas for refuse
cover material (CBA#1 and CBA #2), and allowed for the initial phase construction of Sediment Pond #1 1.
Prior to activation of CRDA No. 3,enlargement of Pond I I would have been required.
TR-18 proposed approval was issued October 13, 1994. The revision allowed for reactivation ofCRDA No.
I, which had been suspended due to potential stability concerns. Reactivation was approved based on
completion of a thorough stability analysis,and commitment to intensively monitor water levels within the pile.
TR-19 proposed approval was issued January 30, 1995. The revision allowed for excavation of a connecting
channel between Sediment Ponds I and 2, and replacement of Pond 7 and 8 CMP spillways with riprapped
open channel emergency spillways.
TR-20 proposed approval was issued December 28, 1995. The revision addressed increase in coal production
and underground mining sequence changes associated with reactivation of mining in the Roadside North
Portals. Modifications to hydrology and subsidence monitoring requirements within the North Portals affected
area were included in the revision.
TR-21 proposed approval decision was issued with one stipulation on March 6, 1995. The revision allowed
for expansion and modification of the coal handling area at the Roadside North Portal. Stipulation No. 14,
attached to the approval, required submittal of a required air emission permit prior to implementation. An
"Initial Approval" construction permit from the Air Pollution Control Division dated June 27, 1995, was
subsequently submitted to the Division, as required by the stipulation.
TR-22 proposed approval decision was issued October 16, 1997. The revision allowed for construction of a
minewater treatment pond (Pond 12),adjacent to existing Pond 5,at the North Portal facility area. The pond
was proposed to provide for surface treatment of minewater from the North Portal,discharged through CDPS
Point 004. Suspended solids discharge limits had been exceeded at the location on several occasions. The
revision included associated modifications to adjacent Pond 5, to accomodate Pond 12 construction.
