DEQ Finds No Significant Impact For Dayton Water Plant Improvement 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: Dayton Water Treatment Plant Improvements

Location: Sheridan County, Wyoming

Total Cost/SRF share: $2,934,169/$2,016,750

The proposed project involves replacement of the following components at the Town of Dayton (Town)’s existing water treatment plant:

Infiltration Gallery

Raw Water Pump Station

Filter Tanks

Supervisory Control And Data Acquisition (SCADA) System.

In order to fund this replacement project, the following funding sources are anticipated:

Funding for the portion of the loan for which principal forgiveness is not received (and for additional operational costs anticipated for the SCADA system) will be obtained from user fees. 

At this time, it is anticipated that this will require an increase of $4/month in user fees.

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. 

The primary impacts of the project will be short-term and construction-related. 

Of primary environmental concern associated with the project is the short-term impact involved with replacing the infiltration gallery, which is located in the south bank of the Tongue River. 

Activities associated with this type of construction will require receipt of the required permits from the U.S. Army Corps of Engineers and DEQ, which the Town has committed to obtaining and adhering to. 

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.
