Section 404 permits: Does your project need a permit to fill?
Some commercial and industrial projects place materials (called fill) in a body of water for various reasons, such as building a facility, adding a road to a facility site, or installing intake and outfall pipes at a power plant. If the project affects any of the waters of the United States (WOTUS), you must first obtain a permit.
Section 404 of the Clean Water Act requires a permit to discharge dredged or fill material into any WOTUS (including wetlands). Before conducting any activities at your facility’s site, it’s crucial to find out whether your project requires a permit to fill.
What’s considered fill material?
The regulations at 40 CFR 232.2 define fill material as any material placed in WOTUS that:
- Replaces any part of WOTUS with dry land, or
- Changes the bottom elevation of WOTUS.
Fill material excludes trash and garbage. Common examples of fill material are:
- Construction debris,
- Materials used to create a structure/infrastructure,
- Rock,
- Sand, and
- Soil.
Whenever fill material is dumped, placed, or deposited in WOTUS, a “discharge of fill material” occurs. Examples (according to 232.2) range from road fills to commercial and industrial site development fills.
The Environmental Protection Agency and the U.S. Army Corps of Engineers (USACE) jointly administer the Section 404 permit program. The USACE typically issues the permits unless a state or tribal program is authorized to issue them.
Does your project require a permit to fill?
To answer this question, you’ll need to address a few more questions:
1. Will fill materials enter WOTUS?
The first step is to determine whether Section 404 regulations cover any on-site waterbodies.
The Aquatic Resource Delineation Report is a required part of the permitting process. It identifies any on-site aquatic resources (i.e., waterbodies or wetlands) subject to permitting rules. Businesses typically hire consultants to develop the report.
If you need help figuring out the status of your aquatic resources, you can request the USACE to make a written jurisdictional determination of whether Section 404 rules apply to any on-site waterbodies or wetlands.
2. Is the planned discharge of fill exempt?
Not all fill discharges require a Section 404 permit. Examples include:
- Conducting ongoing farming and ranching activities (such as minor drainage and harvesting);
- Maintaining drainage ditches, dams, and levees; and
- Building and maintaining irrigation ditches, farm and stock ponds, and farm and forest roads.
See 232.3 for the comprehensive list of discharge activities that don’t require a permit.
3. What impact will the fill discharge have?
The potential impact that your project will have on WOTUS determines the type of permit you need: general or individual.
General permits are issued for discharges that have only minimal adverse effects on WOTUS. They’re based on specific activities and typically require much less processing time, allowing projects to begin sooner. The types of general permits include:
- Nationwide permits (authorize activities across the U.S.),
- Regional general permits (authorize activities in a specific area), and
- Programmatic general permits (authorize activities already regulated by existing state, local, or federal programs).
Individual permits are issued for discharges that may have significant impacts on WOTUS. They require case-by-case evaluations of each project.
When starting the Section 404 permitting process, keep these things in mind:
- The permit requirements apply both to permanent and temporary projects, like using fills to access a work area for a limited time.
- You can request to meet with the USACE before applying for a permit. It’s an informal meeting during which the USACE offers guidance and insights that could help reduce your application’s processing time.
- Check with the state to identify any state-level permitting requirements.
Key to remember: If a project’s discharges of fill material could impact the waters of the United States, it may require a Section 404 permit under the Clean Water Act.
