Piqua Expanding Wastewater Treatment Plant; Receives Financing from Ohio EPA

Piqua is receiving a loan from Ohio EPA to expand its wastewater treatment plant, eliminating a sanitary sewer overflow and improving water quality in the Great Miami River. Piqua’s project is one of 25 projects statewide that received funding from Ohio EPA in July, totaling $475 million, a one-month record for the loan programs.

By expanding the aging plant, the city is increasing treatment capacity and efficiency, and reducing nutrient loads in plant effluent discharge. Nutrients such as phosphorus and nitrogen contribute to harmful algal blooms.

Created in 1989, the Water Pollution Control Loan Fund (WPCLF) provides below-market interest rate loans for communities to improve their wastewater treatment systems. The $53.2 million loan has a 0.8 percent interest rate, including a zero-interest rate on costs associated with nutrient reduction improvements. Additionally, $50,000 of principal does not have to be repaid. The city will save an estimated $20.7 million compared to a market-rate loan.

In addition to improvements to publicly owned treatment works, WPCLF loans have been provided for agricultural best management practices, home sewage system improvements, landfill closures and water quality-based storm water projects. The WPCLF provides technical assistance to public wastewater systems in a variety of areas from the planning, design and construction of improvements to enhancing the technical, managerial and financial capacity of these systems. WPCLF loans also make possible the restoration and protection of some of Ohio’s highest quality water bodies through the fund’s Water Resource Restoration Sponsor Program.

Ohio EPA’s revolving loan funds are partially supported by federal grants and designed to last indefinitely through repayment of loans and investments in bonds. The loan program is managed by Ohio EPA’s Division of Environmental and Financial Assistance, with assistance from the Ohio Water Development Authority. Ohio EPA is responsible for program development and implementation, individual project coordination, and environmental and other technical reviews/approvals of projects seeking funds. The Ohio Water Development Authority provides financial management of the fund.

The Ohio Environmental Protection Agency was created in 1972 to consolidate efforts to protect and improve air quality, water quality and waste management in Ohio. Since then, air pollutants dropped by as much as 90 percent; large rivers meeting standards improved from 21 percent to 89 percent; and hundreds of polluting, open dumps were replaced with engineered landfills and an increased emphasis on waste reduction and recycling.
