Public Notice: FONSI Publication Notice for Cheyenne Crystal By-Pass Project



As required by guidelines for the Wyoming State Environmental Review Process, the Wyoming Department of Environmental Quality (DEQ) has performed an environmental review on the proposed State Revolving Fund (SRF) supported action below:
Project: Crystal Bypass Pipeline
Location: Crystal Reservoir, Laramie County, Wyoming
Total Cost/SRF share: $3,800,000/$1,254,000

The project will include the construction of a new 20-inch, 10,471-foot raw water transmission pipeline, which will allow raw water conveyance to Sherard Water Treatment Plant when Crystal Reservoir is unavailable. The pipeline will require the construction of a new control valve and meter house, located on City of Cheyenne property.

The project is funded through a Wyoming Water Development Commission grant of 2/3 of the total project cost ($2,546,000) and the remainder SRF loan ($1,254,000). Water rates will not be increased to repay the loan.

No significant adverse environmental impacts will occur due to this project. The proposed project will not adversely affect wetlands, prime agricultural lands, threatened or endangered species habitat, historical sites, or sites with environmentally sensitive characteristics. Special attention will be paid to mule deer sensitive winter habitat. The primary impacts of the project will be short-term and construction related.

The review process did not indicate significant environmental impacts would result from the proposed action. Consequently, DEQ has made a preliminary decision not to prepare an Environmental Impact Statement (EIS). DEQ has taken this action on the basis of a review of the environmental assessment document and other supporting data, which are on file at the DEQ Cheyenne Office. The public may review these documents upon request.

Comments supporting or disagreeing with this decision may be submitted for DEQ consideration. Address all questions and comments to Shawn King, SRF Project Manager, Department of Environmental Quality, 200 W. 17th St. Suite 200, Cheyenne, WY 82002, Tel. (307) 777-6941 or email: After evaluating comments received, DEQ will make a final decision; however, DEQ will take no administrative action for at least 30 days after publication of this Finding of No Significant Impact.
