Stormwater Rules and Notices-Industrial Notices

Congress gives EPA authority to develop and implement federal stormwater regulations. Any new or modified regulations must go through a rulemaking process. The process includes a proposal, public comment, and a final rule that must then be implemented and enforced.

EPA also publishes a variety of notices associated with the stormwater program, including draft and final stormwater permits, technical corrections to stormwater permits, and notices on stormwater regulations. Here is more information on the laws, regulations, proposed and final rules, and other public notices applicable to the NPDES stormwater program.

  • Final NPDES Stormwater Multi-Sector General Permit for Industrial Activities (PDF)(516 pp, 4.6 MB, About PDF) (September 29, 1995)
• Extension of NPDES Permit Deadline for Stormwater Discharges for Oil and Gas Activity That Disturbs One to Five Acres (PDF)(4 pp, 186 K, About PDF) (March 09, 2005) – EPA extended until June 12, 2006, the regulatory deadline that would require stormwater permit coverage for oil and gas construction activities that disturb between one and five acres of land. The additional time was used to consider comments from stakeholders and the economic, legal, and procedural implications related to controlling stormwater discharges from the sites. The extension also addressed EPA’s intent to develop and propose a regulation by September 12, 2005, that would address stormwater discharges from the oil and gas construction sites.
