Wetlands State Resource Locator


Note: Most states have enacted laws and regulations to protect wetlands. In many cases, these rules are established to define the state's role in the "404 permit/401 certification process." This process involves the U.S. Army Corps of Engineers and your state environmental agency. To learn more about the wetlands permitting process go to the CICA Wetlands Regulations/Permit page.

Primary State Wetlands Web Page. This web page should explain the state wetlands program and provide links to various wetlands resources.

Construction Permit Process - State Rules

  • How Are Wetlands Activities Regulated by Montana? The Department of Environmental Quality (DEQ) conserves wetlands under the Montana Water Quality Act. The DEQ Permitting and Compliance Division identifies five specific types of permits or regulations that could apply to wetlands depending upon the activity proposed. These are the Storm Water Discharge General Permit, the Streamside Management Zone Law, the short-term exemption from Montana's Surface Water Quality Standards (3A Authorization),and Montana Land-Use License or Easement on Navigable Waters. Rules established under other statutory schemes, such as the Lakeshore Protection Act and the Montana Dam Safety Act, may also apply.

  • Mitigation Measures. Mitigation can include complete avoidance of the negative impact, minimizing the impact, or compensating for the impact. Popular measures are wetland restoration, creation, enhancement, and preservation. Montana generally follows the sequence for mitigation required under the Clean Water Act: avoidance; impact minimization; and mitigation.

Regulatory Definitions

  • Wetlands. Wetlands include marshes, swamps, potholes, wet meadows, fens, impoundments, ponds, and sloughs. They generally have water on or near the surface, all or part of the year; distinctive poorly drained soils that develop certain physical traits due to the presence of water; and vegetation, composed of hydrophytes, adapted to live in wet soils. Montana relies on the definition of wetland found in the 1987 Wetland Delineation Manual issued by the Corps of Engineers.

  • Wetland Categories.

  • Regulated Wetland Activities. Persons cannot cause pollution of any state waters or place or caused to be placed any wastes that will cause pollution; violate any provision set in a permit or stipulation; site and construct a sewage lagoon less than 500 feet from a water well; cause degradation of waters; violate an order issued under the Water Quality Act; construct, modify, or operate a disposal system without a permit; construct or use any outlet for sewage discharge without a permit; discharge sewage or other wastes into state waters without a permit. The construction or commencement of construction for any activity requiring a state water quality certification also cannot occur unless the state has issued a certification or has waived certification.

  • Exempt Wetland Activities.
