The 1992 Needs Survey Report to Congress provides the U.S. Environmental Protection Agency's detailed estimate of the eligible capital costs to build publicly owned municipal waste water treatment facilities and capital/program development costs for other eligible activities necessary to comply with the requirements of the Clean Water Act (CWA). This includes storm water, nonpoint source and estuary programs. The survey focuses on the expanded CWA funding eligibilities under the State Revolving Fund in the 1987 Amendments to the CWA. Models were used to supplement documented needs estimates for combined sewer overflows. Models were also used to develop preliminary urban storm water and agricultural and silvicultural nonpoint source pollution control implementation costs since very little documentation of specific projects or costs was available from the States.
