Stormwater Regulations Revision to Address Discharges from Developed Sites

a.k.a. Stormwater Regulation Revisions - Post Construction


RIN: 2040-AF13 (What's this?)

Docket No.: Not yet available (What's this?)

Current Phase: Pre-Proposal (What's this?)

Abstract:
Stormwater discharges from developed areas are a major cause of degradation of surface waters. Stormwater conveys pollutants to nearby waterbodies and can impact the hydrology of waterbodies because of increased stormwater discharge volumes and velocities. Current stormwater regulations were promulgated in 1990 and 1999.

In 2006, the Office of Water asked the National Research Council (NRC) to review the stormwater program and recommend ways to strengthen it. The NRC Report, which was finalized in October 2008, found that the current stormwater program "...is not likely to adequately control stormwater's contribution to waterbody impairment" and recommended that EPA take action to address the harmful effects of stormwater. This action could propose requirements for managing stormwater discharges from newly developed and redeveloped sites and may propose regulating additional municipal separate storm sewer systems
