Dear Mr. Bramble:
The Division has received your letter of August 24, 2000 on August 29, 2000 regarding the Camas Tower Pit
Amendment. We are responding to your comments as follows:
1. We are sending a copy of your letter to the applicant and will ask them to revise the distance to
the City of Brighton. We will also give them the opportunity to respond to your concems. Any
responses will be forwarded to you.
2. The Division does not have any control over noise or impacts on air quality. Noise issues are
the responsibility of the Country and most air quality and dust issues should be directed to the
Air Quality Control Division of the Colorado Department of Public Health and Environment.
Although we understand your desire [o see a wet mining operation, the Division does not have
the authority to determine the type of mining method to be used.
3. The Division's Rules and Regulations require a 200 foot buffer from structures unless the
applicant can show that mining closer will not impact the structures stability. The set back
impacts to the hydrologic balance caused by flooding of the river and subsequent flows of the
floodwaters into the pit will be evaluated. There is also a possibility that the Urban Drainage
and Flood Control District may have some set-back requirements.
4. The Construction Materials Rules and Regulations Rule 3.1.3 requires that "All reclamation
shall be carried to completion by the operator with all reasonable diligence, and each phase of
reclamation shall be completed within five (~) years from the date the operator informs the
Board or Office that such phase has commenced, unless extended by the Board or Office." The
timetable for mining and reclamation on page 13 of the application shows three phases with
mining ending in phase I after 3 years. Phase 2 after 8 and Phase 3 after 9. Therefore, it
appears that reclamation on Phase one will store in 3 to 4 years.
In response to your request for natural vegetation and trees of four inch caliper or greater be
planted within the 600 foot buffer area as a noise and environmental barrier, the Division has no
authority to require reclamation work or the plantings beyond the areas disturbed by the mining
activity.
Since your letter expressed your issues as "concerns" rather than "objections" it is not clear if you wish
to become a formal objector with parry status. Please refer to page 2, Paragraph II in the enclosed
