FAX: 13031832-8106 April 4, 1996 Mr. Glen Golden, Civil Engineer Office of Surface Mining Western Regional Coordinating Center 1999 Broadway, Suite 3400 Denver, Colorado 80202-5733 Re: Bond Forfeiture -Ohio Creek No. 2 Mine (Permit No. C-80.002) Dear Mr. Golden: I~~~ DEPARTMENT OF NATURAL RESOURCES Roy Romer Governor lames 5. Lochhead Ezeculive Director Michael B. Long Division DnKlor This letter is provided to respond to your correspondence of March 28, 1996. It is our hope that with this response, your agency can agree that the existing Ohio Creek No. 2 Mine reclamation plan and bond are adequate. Our goal is to initiate the reclamation of the site as soon as possible. Our responses are presented~t following the reiterated OSM question. - Will the site be reclaimed in accordance with the approved permit reclamation plan? It is our intent to reclaim the site in accordance with the existing permit reclamation plan. At this time, we do not foresee any need for significant deviations from the plan. - Ors 10/4/95, the permittee submitted a request to revise the "regrading and hydrologic control plan. " Ors 10/16/95, DNR approved Technical Revision No. 04, which pertained to backfilling and grading operations. Does Technical Revision No. 04 include the revisions to the regrading and hydrologic control plan? In addition, other than a rescheduling of reclamation tasks, what changes were made to the permit backfillirsg and grading plan as a result of Technical Revision No. 04? In general, Technical Revision No. 04 provided additional detail regarding the backfilling and grading plan. This detail included material balance information, better mapping, and better site cross-section information. The plan also provided post-mining drainage control details. According to,finding X~7l, page 17, of the OSMJune 1987 Mining Plan Decision Documera, portals are to have an MSK4 approved sea! and be backfilled and graded as shown in Exhibit 9. An unsigrsed, undated sketch of the proposed portal reclamation was found in the permit, but nowhere in the DNR files could there be found a certification attesting to the fact that the portals were reclaimed as planned. State Rule 4.07 requires verification that underground openings have been adequately reclaimed. What information is available, e.g. an engirseer's certification, that would attest to the adequacy of the reclaimed portals? To the best of our knowledge, the portals have been backfilled with a minimum of 25 feet of inert material. It is also our understanding that the backfdl was placed against block seals. We are not aware of any specific cer[i5cations to verify this work.
