*The Environmental Protection Agency's Clean Water Needs Survey (CWNS) is required by Sections 205(a)and 516(b)(1) of the Clean Water Act (CWA). The CWNS is a summary of the estimated capital costs forwater quality projects and other activities eligible for SRF support as authorized bythe 1987 CWA Amendments. These activities include both facilities and certain water qualityprogram elements. Activities include the planning, design, and construction of publiclyowned wastewater collection and treatment systems and projects controlling CSOs, SW, and NPSpollutants. Other eligible water quality program elements are those that involve one-time expenditures supporting the CWAgoals, such as program development and implementation. Ongoing expenditures, such as operation and maintenance (O&M)costs, are not included. The 1996 CWNS, a joint effort of the States and EPA, is the twelfth such survey since the CWA was enacted in 1972. *Primary Treatment
