CONSTRUCTION STORM WATER PERMITTING IN REGION 6:

Under Phase I of the Storm Water Program, permits for discharge of storm water from construction activities that are part of a common plan of development or sale disturbing five or more acres have been required since October 1, 1992.  Phase II of the storm water program requires permits for "small" construction activities in the 1-5 acre range starting March 10, 2003.  There are some waivers available and a fact sheet and help with the "Low Rainfall Erosivity" ("R" Factor) waiver is available on-line.

The EPA-issued general permit for storm water associated with construction activities (Construction General Permit or CGP) is available for construction projects in New Mexico; oil & gas and agriculture point source (e.g., Concentrated Animal Feeding Operations-CAFOs, etc.) related construction projects in Oklahoma; oil & gas related construction projects in Texas; and construction projects on Indian Country lands in Louisiana, New Mexico (except Navajo and Ute Mountain Ute reservations -covered by the permits for EPA Regions 8 & 10). The requirements of the 2008 CGP are similar to the previous 2003 permits and will authorize the discharge of pollutants in storm water runoff associated with construction activities in accordance with the terms and conditions described therein. The CGP requires construction operators to submit a Notice of Intent (NOI) to be covered under the CGP. The NOI includes basic information about the operator and the project site. Prior to submission of the NOI, operators must develop a Storm Water Pollution Prevention Plan (SWPPP). The SWPPP includes a description of the Best Management Practices (BMPs) that will be used to reduce pollutants in the storm water discharges. The CGP also requires operators to conduct regular site inspections, comply with Endangered Species Act requirements, and submit a Notice of Termination when construction is complete.

NOTE: The CGP allows oil and gas construction projects to obtain coverage IF NEEDED. Click here for the status of the current exemption for uncontaminated stormwater runoff from oil and gas exploration, production, etc. construction projects.(return to top)
