Description/Agenda

November 26, 2025 MT. PLEASANT PUBLIC NOTICE OF FINDING OF NO SIGNIFICANT IMPACT TO ALL INTERESTED GOVERNMENTAL AGENCIES AND PUBLIC GROUPS The Division of Water Quality (DWQ), Utah Department of Environmental Quality (DEQ), herewith publishes a Finding of No Significant Impact (FONSI) for the Mt. Pleasant Sewer Lagoons Improvements located in Mt. Pleasant, San Pete County, Utah. An Environmental Assessment (EA) was developed to examine potential environmental impacts associated with the project. As required by guidelines for preparing Environmental Impact Statements (EIS), an environmental review was performed on the proposed State of Utah, DWQ action below: PROJECT INFORMATION PROJECT NAME: Mt. Pleasant Lagoon Improvements MAILING ADDRESS: 106 West Main, Mt. Pleasant, Utah 84647 PROJECT LOCATION: The proposed project is located at the site of the existing sewer lagoons off W 17750 N in Mt. Pleasant City. ESTIMATED PROJECT COST: $1,744,867 PROJECT NUMBER: SRF 275 FUNDING: $2,535,000 from the Utah Water Quality Board. PERMIT INFORMATION FACILITY NAME: Mt. Pleasant Sewer Lagoons PERMITTEE NAME: Mt. Pleasant City MAILING ADDRESS: 106 West Main St., Mt. Pleasant, Utah 84647 TELEPHONE NUMBER: 435-462-2456 PERMIT NO.: UTOP00128 BACKGROUND Mt. Pleasant City's sanitary sewer system was constructed in the late 1970's and early 1980's and collects sewer flows from homes and businesses within current City limits. The collection system conveys all sanitary flows to the City's wastewater treatment lagoons. The collection system consists of approximately 27.1 miles of gravity sewer pipeline, which range in diameter from 6 inches to 12 inches. Due to Mt. Pleasant City's topography, the sanitary sewer collection system does not currently include any sewer lift stations. Based on population data obtained from the United States Census Bureau, Mt. Pleasant City had a population of 3,698 in 2020. As the population continues to increase, additional capacity within the sanitary sewer collection system will be consumed. The Utah Water Quality Board approved funding for this project and authorized a $2,535,000 loan at 2.5% over 30 years. Although, the current project cost is $1,744,867. The proposed project will be completed primarily within the fence line of the existing treatment facility. The project will occur primarily on paved roads or previously developed areas. No wetland impacts are anticipated for the project. The proposed project would not modify or eliminate any recreational open space and would be unlikely to impact any agricultural lands. The project should not cause any increased impacts to air quality since operational and fugitive dust control measures are planned during construction. The additional discharge should not significantly alter stream flow conditions or result in stream bank modifications. The increased capacity will allow the plant to meet the requirements of the DWQ permit. An Environmental Assessment (EA) was prepared by JUB Engineers as part of Mt. Pleasant City's Capital Facilities Plan. The EA evaluated the potential environmental effects and consequences of the proposed upgrades. ANNOUNCEMENT This notice announces the availability of the EA which is included as an Amendment to the Capital Facilities Plan, for public review and comment. Based on the information on the EA, as summarized here, DWQ determines that the proposed action will not significantly impact water quality. Additionally, the review process did not indicate significant environmental impacts would result from the proposed action. The preliminary decision is to not prepare an EIS and the DWQ is issuing a FONSI for the proposed action. This action is taken on the basis of a careful review of the Capital Facilities Plan, environmental information documents, antidegradation review, and other supporting information. These documents are available for public review online on the DWQ's Public Notice Webpage. Comments supporting or disagreeing with this decision may be submitted for consideration by DWQ. After evaluating the comments received, DWQ will make a final decision. No administrative action will be taken on the project for at least thirty (30) calendar days while advertising the FONSI, Capital Facilities Plan, and EA. Questions or comments may be directed to Andrew Pompeo via email at apompeo@utah.gov or if necessary via telephone at (385) 320-1057. (Note: Please Include 'Mt. Pleasant Lagoons FONSI' in the subject line of any email) John K. Mackey P.E. Executive Secretary, Utah Water Quality Board DWQ-2025-009042
