Woody plant density will be determined by conducting a total census within each clump.
All shrub and tree species , which have been established over two growing seasons and
area alive and healthy, will be identified and counted.
The results of revegetation sampling studies will be contained in the annual
reclamation report. The presentation will include the raw field data, a
summary of the analyses, and results of the analyses.
(2)(t) Disposal of Debris, Acid - Forming and Toxic Forming Materials
There is no indication that any acid - forming or toxic forming materials will be encountered
on site. Please refer to Section 2.04.6. Please refer to Section 2.05.3(8) for a discussion
of the applicant's method to handle debris and non -coal waste.
If sustained combustion of debris or non -coal waste becomes a problem the applicant will
be prepared to react appropriately. Chemical fire extinguishers will be available in the
shop warehouse area and on mobile equipment. A water truck will be available to respond
to any problem area. Earth moving equipment may be available to smother a fire if
necessary.
(2}(g) Sealing and Managing Mine Openings
Sealing of the openings which access the underground coal mining operations at the
New Elk Mine will be completed upon the final closure of the operation. Sealing will
consist of installation of bulkheads near the surface of the openings to prevent entry and
collapse of the surface. Bulkheads will consist of a minimum of an 8 inch thick block seal
as shown on Figure 15- Typical Mine Opening Seal. Particular care will be taken to ensure
that excessive pressures do not collect on the inside of the seal and cause seepage or
