Based upon my cursory review of the technical revision application for stormwater matnagement at
the Canon City quarry submitted by T.H.E. on January 16, 1996, I advise that the Division deny
the application at this time and request T.H.E. to submit an application for a permit :unendment.
The purpose for such a request is that T.H.E. has proposed an alternative solution for stormwater
management that is not in conformance with the November 25, 1995 Board Order; additional
acreage will need to be permitted, and additional parties will need to be noticed and given a chance
to comment. I suggest that we allow T.H.E. to apply the $150 application fee toward the $1,550
application fee for an amendment. I also suggest that we address the Board at the Febnuary 21-22,
1996 Meeting for a modification of the original Order regarding stormwater.
Mr. Ken Klco has submitted a technical revision application for stormwater management on behalf
of T.H.E. which does not include the detailed engineering calculations and designs or approvals
as specified in the November 25, 1995 Board Order. Mr. Klco's application conCtins only a
concept of how stormwater might be managed in the future. It is obvious to me that the. permitting
of an acceptable stormwater management plan for the Canon City Quarry will require an extensive
amount of time, planning, and negotiation between all parties concerned.
I advise that we request the Board's permission to allow the operator additional time to prepare an
acceptable amendment application and that the Board Order be modified to require T.H.E. to
submit an application for a permit amendment with the following information no later than
April 24, 1996:
Stormwater runoff calculations for peak flow and volume of both [he 10-year, 24-hour storm
and 100-year, 24-hour storm events for both the disturbed area watershed and the upland
non-disturbed watershed (6-hour storm events may be substituted as appropriate).
