DEPARTMENT OF AGRICULTURE Rural Development Red Rock Rural Water System: Notice of Availability of an Environmental Assessment storage. The total storage volume of 400,000 gallons (clearwell and GSR) wil provide just over 8 hours of storage at a demand of 800 gpm. A submersible ac- tive mixer will be installed in the GSR to prevent stratification and ensure proper mixing DGR Engineering, an environmental consultant, prepared an environmental assessment for RUS that describes the project, assesses the proposed project's environmental impacts, and summarizes as applicable any mitigation measures used to minimize environmental effects. RUS has conducted an independent eval uation of the environmental assessment and the replacement of outdated control equipment at the Lake Augusta WTP Red Rock Office, and remote sites. AGENCY: Rural Utility Service, USDA Rural Development ACTION: Notice of Availability of an En- Questions and comments should be sent to RUS at the address provided. RUS wil accept questions and comments on the en vironmental assessment for 14 days firom the date of publication of this notice. Any final action by RUS related to the proposed project will be subject to, and contingent upon, compliance with all relevant Federal environmental laws and regulations and completion of emwiron- mental review procedures as prescribed by 7 CFR Part 1970. Environmental Policies and Procedures A general location map of the proposal is shown below vironmental Assessment To supply the new WTP the existing raw water piping will be rerouted from the existing WIP to the new WIP The new well raw water piping will also be tied into this line. The new piping will be sized to minimize head loss while also providing adequate velocity to prevent solids from SUMMARY: Notice is hereby given that the Rural Utility Service (RUS), as re quired by the National Environmental Policy Act, is issuing an environmental as sessment (EA) in connection with possible impacts related to a project proposed by Red Rock Rural Water System (RRRWS) of depositing in the pipe. Jeffers, MN. The proposal is for construc tion of a new 800 gpm Water Treatment Plant (WTP) to replace the existing water treatment facility. The new WTP would be tied into the existing Great Bend Wellfield and would include the construc- tion of two new wells. Red Rock's existing WIP is located approximately four miles northwest of the City of Windom, at the intersection of Cottonwood County Road 13 and County Road 4. Existing wellfield is located southwest of the WIP a quarter mile west of the Des Moines River and on the north side of County Road 14. The new WIP would be located on thee south side of County Road 14, closer to the existing wellfield than the existing WTP Red Rock Rural Water System has submit ted an application to RUS for funding of the proposal FOR FURTHER INFORMATION CON TACT: Edward Gilmore, Area Specialist, USDA Rural Development, 1810 30th ST NW Faribault MN, 507-332-7418, edward gilmore@usda.gov The new WTP will be designed to treat 800 gpm. The preliminary treatment design features a packaged rectangular treatment unit that includes aeration detention, and gravity filtration for iron and manganese removal. The aeration step will oxidize the iron in the water Backwash water will be routed to two infil tration ponds south of the WTP The new WTP will feature a 100,000-gallon con crete clearwell. The clearwell will provide Red Rock operators with a way to examine water clarity inside the WTP and provide supplemental finished water storage vol ume if the onsite Ground storage reservoir is taken out of service Three 400 gpm vertical turbine high service pumps will be installed to provide a total distr bution pumping capacity of 1,200 gpm and a firm pumping capac- ity of 800 gpm. The high service pumps will be on VFDs to provide operational flexibility. The space for two additional pumps will be added for a potential WTP expansion in the future. New piping will be routed to the discharge lines out of the existing WTP Dated: October 30, 2019 and believes that it accurately assesses the impacts of the proposed project. No significant impacts are expected as a result of the construction of the project.
