The Division of Minerals and Geology hereby issues notice, in accordance with Title 34, Article 33, Section 116, Paragraph
4, of the Colorado Revised Statutes, that on March 4, 1999, an application to revise coal mining operations at the Lorencito
Canyon Mine was considered complete for the purposes of filing. The revision was submitted by Lorencito Coal Company,
LLC. All review and comment periods as provided in the Act and the Regulations initiate from this date of filing.
As a result of the delay in the start up of mining operations, Lorencito Coal Company (LLC) has requested a reduction in the
hydrologic monitoring program. Only monitoring frequency has been proposed for reduction; wholesale elimination of
monitoringsites is not proposed. Upon commencement of operations LCC will return to the original hydrologic monitoring
plan.
The combined surface and underground coal mining operation is on land located approximately 3 miles west of Segundo on
Hwy 12. The permit area is further described as follows:
On lands south of the Purgatoire River, lands east of [he South Fork of the Purgatoire and Alamosa Canyon, lands north of
Vermejo Park, and lands west of Widow Woman Canyon containing approximately 17,862 acres.
The above-mentioned tracts of land are shown on USGS 7.5 minute Quadrangle map of Vigil.
A copy of the technical revision application is available for public inspection at the Las Animas County Courthouse, 200 East
First Street, Room 104, Trinidad, CO 81082, and at [he Division office. For additional information or to provide written
comments, contact the Division of Minerals and Geology, Room 215, 1313 Sherman Street, Denver, Colorado 80203,
[phone]. In order for us to comply with regulatory time frames, we request that comments be submitted within fifteen
(IS) days of this letter. If no comments are received by then, we will proceed on the assumption that you have no concerns
with, or objections [o, the applicant's proposal.
