• Tab 12, Exhibit 12-1, Operations Plan). Topsoil replacement depths were
estimated to be 6 inches for rangeland reclamation areas previously
disturbed under Permit 75-36 (Mine Areas 2 and 3), 10 inches for
rangeland reclamation areas associated with Permit C-008-81, and 15
inches for dryland pasture reclamation areas. The various categories of
soil replacement were shown on Exhibit 13-1b, Postmine Soil Replacement
Depths (see SMP No. C-008-81, Volume 10, Tab 13).
The fifth plan was submitted on February 29, 1988 in response to CMLRD's
January 14, 1988 and February 5, 1988 letters to Peabody pertaining to
Nucla Mine Permit (C-81-008) Renewal No. 1 and Nucla Mine Minor Revision
No. 7, respectively. The plan also satisfied the "first annual topsoil
balance requirement" as stipulated in Nucla Permit Revision No. 1.
Three significant modifications were incorporated into the February 29,
1988 topsoil balance. First, Mine Area 5 was omitted from the
life-of-mine operation. Second, Topsoil Stockpile 1 and most of the
disturbed land associated with Mine Area 4 was proposed to be excluded
• from the permit area and turned over to Montrose County per Technical
Revision No. 2 (pending). Lastly, topsail handling activities for Mine
Area 1 were expanded to include the tempoary by-pass road, topsoil
underlying Stockpile 5, and ahead-of-mine topsoil salvage between the
temporary by-pass road and proposed Topsoil Stockpile 13.
Two significant changes are incorporated into this July 1988 topsoil
balance. First, the topsoil salvage area for the farmer Topsoil
Stockpile No. 5 is included in the disturbed land category. Second,
topsoil handling activities for Mine Area 1 are expanded to include
topsoil underlying Topsoil Stockpile No. 13 and additional
ahead-of-mining topsoil salvage above the NE/SW highwall between Topsoil
Stockpile Nos. 8 and 13. Topsoil Stockpile No. 1 and Mining Area No. 4
are still shown on Exhibit 9-3 and 13-1b until Montrose County completes
the landfill licensing procedures and Technical Revision No. 2 is
approved in its entirety (i.e., both change in land use and release of
liability are approved). For purposes of this topsoil balance, topsoil
requirements for Area No. 4 are included. Topsoil Stockpile (TS) No. 1
is included in the topsoil stockpile volumes (Tables 9-3-1 and 9-3-2).
