The Division proposes. to approve Mountain Coal Company's (MCC)
application for a minor revision which proposes to change a number
of permit pages in response to the Division's adequacy review of
the 1990 and 1991 Annual Hydrologic Report (AHR).
A few pages required some revision for the following reasons:
Revised page 2.05-59 should state where the USFS Water
Resources Map is located because it is currently not in
the permit. It was decided that Map 37 would be replaced
with the new Exhibit 2 in the 1991 AHR, as it contains
both the locations of the springs and stockponds and the
locations of the USFS water resources.
Revised page 2.05-97 should be page 2.05-96.
3. Revised page 2.05-101 should be page 2.05-100.
Revised page 2.05-60 was determined to be acceptable at
this time. Previously, page 2.05-60 stated that springs
G-2 through G-24 would be monitored. The page was
changed to reflect the approved monitoring plan in Table
16. The Division's adequacy review of the 1990 and 1991
AHR (see letter dated 1-11-93, question 1 under Springs),
inquired as to why all of these springs were not
monitored. The AHR responses, however, do not mention
the status of spring G-11, G-13, G-15, G-18, G-19, G-21,
and G-23. The Division will address this issue when the
MCC responses to the Division's AHR adequacy letter are
formally reviewed.
