RE: 1995 Annual Reclamation and Hydrology Report, Hayden Gulch
Mine, Permit No. C-80-003, H-G Coal Company.
Dear Mr. Neumann:
The Division has finished its review of the above-mentioned report
and has the following questions or comments:
1. Concerning the Annual Reclamation Report, and Rule
2.04.13(1)(f), the Division believes that, for future reports,
the location of revegetated acreages, and the years they were
seeded, needs more definition. One possible method would be to
add a notation in future Annual Reclamation Reports, under
Rule 2.04.13(1)(f), that would reference Map 2, entitled
"Reclamation Sequence & Drainage Map", found in the TR-63
volume of the permit application.
2. Please provide the Discharge Monitoring Reports for the third
quarter. They do not appear to be in the 1995 Annual Report.
3. For future reports, on the quarterly pond inspection reports,
please provide the Professional Engineer's official stamp next
to the P.E. name and number that are already on the report.
This P.E. certification can be on a cover letter for each
quarter or on each individual report page.
4. As stated in Section 2.05.6 of Volume 1B of the permit
application, the surface water monitoring plan requires that
dissolved oxygen and turbidity be sampled in the field.
However, these two parameters do not appear in Exhibit 4 of
the 1995 Annual Report, although laboratory turbidity results
are given. In the response to the Division's adequacy question
no. 8 for the 1994 Annual Report, TerraMatrix stated that
