The Nationwide Urban Runoff Program (NURP) was a research project conducted by the United States Environmental Protection Agency (EPA) between 1979 and 1983. It was the first comprehensive study of urban stormwater pollution across the United States. [1]
In a report released Thursday, researchers with the Pacific Institute determined that every year, 59.5 million acre-feet of stormwater go uncaptured across the United States — or roughly 53 ...
Stormwater permit regulations issued by the United States Environmental Protection Agency (EPA) govern the permit process. [4] EPA published its "Phase I" stormwater rule, which covers industrial dischargers, in 1990. [5] Most stormwater permits in the U.S. are issued by the agencies in 47 states that have been given authority by EPA.
As stormwater is channeled into storm drains and surface waters, the natural sediment load discharged to receiving waters decreases, but the water flow and velocity increases. In fact, the impervious cover in a typical city creates five times the runoff of a typical woodland of the same size.
The following reports on economic indicators are reported by United States government agencies: Business activity Wholesale Inventories; Industrial Production (Federal Reserve) Capacity Utilization; Regional Manufacturing Surveys (purchasing managers' organizations and Federal Reserve banks) Philadelphia Fed Index (Federal Reserve Bank of ...
The rule states that the CWA specifically exempts agricultural storm water runoff from being considered a point source, but based on the court's decision in the Waterkeeper case, EPA may treat land applications of excessive amounts of manure as a point source. While in general agricultural storm water runoff from CAFOs is a nonpoint source ...
Topsoil runoff from farm, central Iowa (2011). Water pollution in the United States is a growing problem that became critical in the 19th century with the development of mechanized agriculture, mining, and manufacturing industries—although laws and regulations introduced in the late 20th century have improved water quality in many water bodies.

There are now nearly 1,500 jurisdictions with similar policies to address stormwater management. [2] Numerous counties in Maryland have implemented fees and programs to address polluted runoff since the 1980s. [2] In 2010, the U.S. EPA ordered the states in the Chesapeake Bay watershed to reduce stormwater runoff through independent funding ...
