Note — This information on the page concerns projects requiring a Federal permit for the discharge of dredge or fill materials under the Clean Water Act Section 404. By Federal law every applicant for a Federal permit or license for an activity which may result in a discharge into a water body must request State certification that the proposed activity will not violate State and Federal water quality standards.

Water quality standards include:

1. Beneficial Uses of Water - aquatic life, agriculture, recreation, municipal and domestic drinking water supply, industrial supply, and propagation of wildlife;



2. Water Quality Criteria - numeric and narrative limits or bans on substances, water characteristics and activities which impact water quality including discharges of waste materials, sediment and pesticides; procedures which alter concentrations of dissolved oxygen, temperature and turbidity; and any actions which generally increase in-stream toxicity and pollution; and



3. Antidegradation - requires that surface waters whose quality is higher than the applicable standard must be protected and maintained.

Most projects requiring State certification fall into two broad Federal program categories:

1. Those seeking a Federal permit to allow discharges of dredged or fill material (e.g, as a result of navigational dredging; flood control channelization; levee construction; channel clearing; or fill of wetlands for land development) to all waters of the United States, including oceans, lakes, streams, wetlands, and other water bodies. These permits are issued by the U.S. Army Corps of Engineers (Corps) under CWA Section 404. This is a category of activities for which this information sheet is intended



2. Projects involving construction of hydroelectric dams, power plants, and other facilities requiring Federal Energy Regulatory Commission (FERC) licenses.

The State may respond to this type of application in three ways:

1. Waiver - Under Federal law the State may waive its certification authority if it takes no action on an application within a "reasonable time" not to exceed one year. For Section 404 permit projects, the Corps has defined "reasonable time" to be 60 calendar days, starting with receipt of a complete application by the State, but may extend this period up to one year on a case-by-case basis. Waivers carry no conditions, and are, in some ways, equivalent to certification without conditions.



2. Certification - Certification is based on a finding that the proposed Section 404 discharge will comply with all pertinent water quality standards. In order to allow certification, special conditions may be required by the the State in order to remove or mitigate potential impacts to water quality standards. Such conditions must ultimately be included in the Federal Section 404 permit.



3. Denial - The State has the option to deny certification if it is unable to find that the project will comply with water quality standards or other applicable requirements. If a project is denied certification, a Section 404 permit for it cannot be issued by the Federal government. In some instances denial is necessary due to failure by the applicant to meet a procedural requirement or the ability to meet water quality standards. Once the deficiency is addressed, the application for water quality certification may be reconsidered.
