Third Amendment to Finding of No Significant Impact
To All Interested Governmental Agencies and Public Groups
As required by guidelines for the preparation of environmental impact statements, an environmental review has been performed on the proposed Drinking Water State Revolving Fund (SRF) action below:
Project: Water System Improvements
Location: City of Edgemont (Fall River County), SD
Project Number: C462216-01/C462216-02/C462216-03
Total Cost/Srf Share: $4,590,000/$2,590,000/$637,000
The South Dakota Department of Environment and Natural Resources (DENR) issued a Finding of No Significant Impact (FNSI) published on October 1, 2015 for a proposed water system improvements project to be conducted by the City of Edgemont. On July 20, 2017, the first amendment to the FNSI was published. The first amendment involved changing to project scope to remove the rehabilitation of Well No. 2 and instead construct an additional well adjacent to the well to provide another viable water source for the city. Well No. 2 would also be abandoned as a result of the project. On April 25, 2019, the second amendment to the FNSI was published. The second amendment included an increase in funding to address a shortfall caused by construction of an additional well and other project costs.
The third amendment to the FNSI includes an increase in funding provided by an additional Drinking Water State Revolving Fund (SRF) loan which will fund a project to construct an iron removal pretreatment system in the water treatment plant.
After construction of the wells was completed, high levels of iron were found in the raw water which were not detected in preliminary testing nor in testing that was done during construction. The high iron reduces the effectiveness of the existing treatment system and contributes an unpleasant taste and odor to the treated drinking water. The proposed vertical pressure filtration system will remove the iron upstream from the treatment system. This project includes the iron removal system, PVC piping, piping appurtenances, and electrical and supervisory control and data acquisition (SCADA) improvements.
The City of Edgemont was originally awarded a $1,890,000 Drinking Water SRF loan with 63.9 percent principal forgiveness, not to exceed $1,206,890, and a $2,000,000 Consolidated Water Facilities Construction Program grant. In June 2017, the Board of Water and Natural Resources awarded the city of Edgemont a $447,000 Drinking Water SRF loan with 35.2 percent principal forgiveness, not to exceed $157,000, to fund this project. Both loans have a rate of 0 percent with a term of 30 years. On March 29, 2019, the City of Edgemont’s $447,000 Drinking Water SRF loan was increased to $700,000 with 35.2 percent principal forgiveness, not to exceed $246,000, to cover the additional costs associated with the project.
On January 7, 2021, the City of Edgemont was awarded a $637,000 Drinking Water SRF loan with 25.2 percent principal forgiveness, not to exceed $160,000, to fund the iron removal system project. The SRF loan was established at an interest rate of 0 percent with a term of 20 years. Repayment of the SRF loan will be with a water surcharge. Edgemont’s current monthly rate is $62.80 per 5,000 gallons. A monthly surcharge of $5.50 per user is needed to provide the required 110 percent coverage.
The amended project will not affect any historical or archaeological resources. In the event of an archaeological or historical resource being unearthed during construction, work will be stopped and the State Historic Preservation Office will be notified.
The amended project should have no direct or indirect adverse effects on plant life or wildlife. There will be no significant impact to prime or important farmlands. The proposed project will not adversely affect wetlands. If construction activities will occur in waterways or wetlands, the project sponsor will be required to secure a Section 404 permit from the appropriate governmental agencies during design of the project. The proposed treatment facility, if necessary, will be flood proofed to above the 100-year base flood elevation.
The review process did not indicate that significant environmental impacts would result from the proposed action. Consequently a preliminary decision not to prepare an Environmental Impact Statement has been made. This action is taken on the basis of a careful review of the engineering report, environmental information documents, and other supporting data which are on file at the Department of Environment and Natural Resources (DENR), Division of Financial and Technical Assistance, Pierre, South Dakota, and are available for public scrutiny at the Edgemont City Hall in Edgemont, South Dakota.
Comments supporting or disagreeing with this decision may be submitted for consideration by DENR. After evaluating the comments received, the Department will make a final decision; however, no final administrative action will be taken on the project for at least 30 calendar days after release of the Amendment to Finding of No Significant Impact.
