To date the Colorado Department of Public Health and Environment, Air Pollution Control
Division (Division) has received nine complaints of dust problems related to surface mining and blasting
activities at Lorencito Coal Company (Lorencito), located 3 miles west of Segundo on Colorado State
Highway 12, Las Animas County, Colorado. The Division issued a construction permit, number
O1LA0642, for Lorencito Coal Company to conduct surface mining activities to include material
extraction, handling, hauling and stockpiling of materials. In response to complaints received by the
Division, the Field Enforcement Officer (FEO) Mr. Paul Carr conducted several site inspections at the
Lorecito facility to determine compliance with the terms of Lorencito's construction permit number
O1LA0642. Lorencito facility inspections were conducted by the FEO on the following dates:

Lorencito routinely schedules blasting activities for late in the day, however, complaints received
indicated that Lorencito is conducting blasting activities after sunset. The FEO informed Lorencito
employees, Mr. Daniel Risner on Nov. 21, 2001 and Mr. Elmer Bentley and Mr. Bruce Addington on
Nov. 30, 2001, that blasting activities would need [o occur before sunset in order to have enough ambient
light available to detemune compliance with the permit terms for fugitive dust emissions. A review of the
blasting logs provided by Buckley Powder Company indicates that Lorencito conducted blasting after
sunset at least seventeen times in the last two months, based on sunset information available for Trinidad
