INTRODUCTION The active Seneca II Mine Permit ( State Permit No. C- 005 -80, Federal Permit No. CO- 006) was originally submitted to the Division on December 30, 1980 under Colorado's Permanent Regulatory Program and was subsequently approved on September 23, 1981. Five five -year renewals have been issued since Permit C -80 -005 was originally approved; the first on February 17, 1987, the second on February 17, 1992, the third on July 25, 1997, the fourth on February 17, 2002, and current permit term was approved on February 17, 2007 and extends until February 2012. SCC proposes to reduce the size of the original Seneca II permit area to accommodate the new Peabody Sage Creek Mine (PSCM) permit area. The PSCM permit area will include approximately 3,011.9 acres of the original Seneca II permit area. The revised Seneca II permit area will retain 386.5 acres of the original permit area that includes 271.0 disturbed acres. This new Seneca II Mine permit boundary encompasses one isolated watershed and separates runoff from the Seneca II Mine and the new PSCM permit area. The watershed discharges to Pond 008, which is an approved NPDES discharge point. SCC proposes to revise only applicable sections and maps of the original Seneca II PAP to reflect current and future conditions. The currently approved Seneca II PAP will be left intact to provide baseline information and background operational information. The new revised permit area is shown on Map 2.05 MI, Postmining Topography and Permanent Features. There will be a reduction in the amount of reclamation liability for the new Seneca II permit area. In the interim, SCC will continue to hold the full reclamation bond (based on SL04 bond calculation) of $3,973,637 on the entire Seneca II permit area until PSCM receives permit approval and submits a reclamation bond for their new permit area (which includes 3,011.9 acres of the original Seneca II permit area). Now that the new Seneca II permit area has been reclaimed and has received Phase I bond release and partial Phase II bond release, SCC will revise only applicable sections of the original PAP to reflect current and future conditions, these sections are provided in this Permit Application Package and are titled: • Introduction • Rule 2.03.4 — Legal, Financial, Compliance and Related Information • Rule 2.04.7 — Hydrology Description and Monitoring Plan • Rule 2.05.3 — Operation Plan • Rule 2.05.4 — Reclamation Plan • Rule 3.02 — Performance Bond Requirements for Surface Coal Mining and Reclamation PR -02 1 6/10
