Underground Injection Control Program

You will need Adobe Reader to view some of the files on this page. See EPA's PDF page to learn more.

The Underground Injection Control (UIC) program is designed to prevent ground water contamination from injection wells. Most injection wells are relatively simple devices used to place fluids into the shallow subsurface under the force of gravity. Examples include sumps, drywells, and drainfields. The threat posed to ground water quality depends mostly upon the volume and nature of the fluids injected, well construction, and the hydrogeologic setting. The federal UIC regulations and additional state requirements are based upon a protective performance standard. See our UIC frequently asked questions for more information.

Public Comment Opportunities

Public comments accepted from December 13, 2013 – January 13, 2014 on Proposed Modification of an Existing Class 1 Underground Injection Control Permit AK-1I0006-A for Existing Class I Non-Hazardous Industrial Waste Injection Wells at the Trading Bay Unit, Cook Inlet, Alaska.

The request for modification is to singularly increase the injection pressure limitation currently set in the permit at 3500 pounds per square inch (psi) to an upper limit of 4500 psi. Trading Bay is an oilfield located offshore in Cook Inlet, Alaska. The field has been developed from offshore platforms four to six miles offshore in Cook Inlet. The EPA UIC Class I permit includes specific injection wells located on Dolly Varden Platform, King Salmon Platform, Steelhead Platform and Grayling Platform issued on October 19, 2005 and is effective through October 18, 2015. To date, one (1) Class I well offshore at Dolly Varden Platform has been approved for Class I injection.

UIC Manuals and Guides

EPA's Onsite Wastewater System Treatment Manual (OWTS) - This manual complements the "Design Manual for Onsite Wastewater Treatment and Disposal Systems" (EPA-625/180-012) that was originally published in 1980. The Manual provides the latest information on onsite system management, siting, design, installation, maintenance, monitoring and replacement. It is designed to help users assess and select the best and most suitable sets of technologies and techniques that are appropriate for local site specific conditions. The manual was written to promote the use of an integrated risk/performance-based approach to OWTS design. Information on OWTS cost and effectiveness has been included.

Small Entity Compliance Guide: "How the New Motor Vehicle Waste Disposal Well Rule Affects Your Business" (33 pp, 460K) -
This guide provides information about motor vehicle waste fluid management and is available in PDF format. For a CD ROM version of the please contact Kirk Robinson or call him at (206) 553-2104. More information about shallow injection wells.

A video that looks at the real life challenges and successes experienced by three different communities when faced with contaminated drinking water supplies is available to the public. Titled "The Problem with Shallow Disposal Systems," the video explains that shallow disposal systems are a common, but often over-looked source of contamination to drinking water resources. In addition, the video also shows that there are simple and preventative steps a community can take to reduce threats to their water resource without disrupting the community's economy or going into financial debt. For more information about the video or if you would like to order a free copy, please contact Kirk Robinson at (206) 553-2104.
