Introduction
The Division of Minerals and Geology (Division) has conducted this internal review in
accordance with Rule 2.08.3 of the Colorado Surface Coal Mining Reclamation Act and the
Regulations of the Colorado Mined Land Reclamation Board for Coal Mining (Rules). The Rules
contain the complete text of rules referenced throughout this document. The review is of the
Perini[ of February 28, 1997 and the associated Perini[ Application Package (three volumes).
(The Perini[ and the Permit Application Package are collectively referred to as the PAP in this
document.) However, previous permits, findings, reviews, files of the Division, and reports were
researched as were appropriate to the review.
The Coal Ridge No. 1 Mine, an underground mine, is located in Garfield County, Colorado,
approximately 7 miles west of Glenwood Springs, Colorado. The mine is just south of the
Colorado River, and borders a section of County Road 335 approximately 1.5 mile east of the I-
70 Newcastle interchange (Exit 105).
The PAP describes an operation much lazger than was experienced or is now anticipated due to
premature closure of the mine. The Division does not require revision of the description of
operations to reflect actual or currently anticipated operations, so long as currently envisioned
actions are within the scope of approved operations.
