Stormwater

Precipitation often transports pollutants into nearby water bodies. During precipitation events, storm water runoff (also referred to as storm water discharges) can come into contact and transport pollutants such as fertilizers, pesticides, fecal matter, oil and grease, trash, and sediment such that water quality is adversely affected.

Federal regulations (see 40CFR 122.26) require permits for storm water discharges associated with industrial activity (including construction projects disturbing more than one acre of land) and Municipal Separate Storm Sewer Systems (MS4s). These permits require controls on storm water discharges, primarily through the use of best management practices, designed to reduce the transport of pollutants in storm water to waters of the United States.

EPA Region 8 is responsible for permitting storm water discharges associated with industrial activity and Municipal Separate Storm Sewer Systems (MS4s) where they are the permitting authority. The Region 8 office also conducts industrial and municipal inspections to ensure compliance with federal storm water regulations.

NPDES Permitting Authority - EPA has issued general permits for industrial storm water discharges where EPA is the NPDES permitting authority.  Within EPA Region 8, EPA retains NPDES permitting authority only for the following areas: Federal facilities in Colorado, and Indian Country Lands in: Colorado, Montana, North Dakota, South Dakota, Utah and Wyoming.  For all other areas in the Region, the appropriate State is the NPDES permitting authority (see "Regional & State Contacts" link).

*PUBLIC NOTICE*

Region 8 of EPA is hereby giving notice of its tentative determination to issue an NPDES general permit for storm water discharges from regulated industrial activities. The general permits are applicable to federal facilities within the State of Colorado and Indian country within the Region 8 states. For more information, visit the web page for Region 8 industrial stormwater activities.

NOTE: the comments period has been extended until February 13, 2007.
