A detailed, science-based assessment of challenges, opportunities and research gaps associated with urban stormwater management. Useful, but lengthy, summary of the science framework that underlays current stormwater and green infrastructure initiatives.
Does the NPDES program work? It's hard to tell, since requirements for monitoring vary depending on the regulating entity and the type of activity. Likewise, state and local stormwater programs are plagued by a lack of resources to review stormwater pollution prevention plans and conduct regular compliance inspections. So the answer about the NPDES program is "maybe" in "some places." To address the seeming intractability of this problem, the EPA requested that the National Research Council (NRC) review its current permitting program for stormwater discharge under the Clean Water Act and provide suggestions for improvement.
