Dredged Material

Dredged Material Management

Comparison of Dredged Material to Reference Sediment
The Environmental Protection Agency (EPA) is proposing to revise the Clean Water Act Section 404(b)(1) Guidelines (Guidelines) to provide for comparison of dredged material proposed for discharge with "reference sediment," for the purposes of conducting chemical, biological, and physical evaluations and testing.

Inland Testing Manual - This joint EPA and Corps document, "Evaluation of Dredged Material Proposed for Discharge in Waters of the U.S. - Testing Manual" (ITM), provides guidance regarding technical protocols under Section 404 for evaluating proposed discharges of dredged material associated with navigational dredging projects.

Beneficial Use of Dredged Material - An important goal of managing dredged material is to ensure that the material is used or disposed of in an environmentally sound manner. The Federal Standard Paper provides guidance on using dredged material as a resource to achieve environmental and economic benefits and is intended as a companion piece to the Beneficial Use Planning Manual.

Coral Reef Guidance

1999 Memorandum to the Field - emphasizes the protection afforded the Nation´s valuable coral reef ecosystems under the Clean Water Act (CWA) Section 404 regulatory program, the Marine Protection, Research, and Sanctuaries Act (MPRSA) Sections 102 and 103 provisions, Rivers and Harbors Act (RHA) Section 10 requirements, and Federal Projects conducted by the Corps.

Regulatory Flexibility

1995 Memorandum to the Field - identifies regulatory flexibility under Section 404 of the Clean Water Act to those small landowners impacting less than two acres of wetlands on their property.

1993 Memorandum to the Field - clarifies that the level of review associated with a permit application is linked to the nature of anticipated environmental impacts. Thus, small projects with fewer impacts require less review.


Eco-Logical - Eight federal agencies (BLM, DOI, EPA, FHWA, NOAA, NPS,USACE and USFWS) have agreed on an ecosystem approach for addressing natural resource identification, avoidance, minimization and mitigation into a systematic, step-wise process that starts at the beginning of the transportation planning process and concludes with establishing programmatic approaches to recurring natural resource issues that are implemented at the project level.

Surface Coal Mining Operations

Surface Coal Mining Initiative Actions - This page provides updates and background information regarding EPA's recent activities under the Clean Water Act Section 404, Clean Water Act Section 402, and National Environmental Policy Act (NEPA).

Joint Procedures Framework MOU for Surface Coal Mining Permit Applications - February 10, 2005 - The U.S. Office of Surface Mining (OSM), U.S. Army Corps of Engineers (COE), U.S. Environmental Protection Agency (EPA), and U.S. Fish and Wildlife Service (FWS) have coordinated in the development of a Memorandum of Understanding (MOU) to improve coordination and information sharing among the agencies responsible for reviewing and processing Surface Mining Control and Reclamation Act (SMCRA) and Clean Water Act (CWA) Section 404 dredge and fill permits.

1999 Memorandum of Understanding - establishes a process for improving coordination among the U.S. Office of Surface Mining, U.S. Environmental Protection Agency, U.S. Army Corps of Engineers, U.S. Fish and Wildlife Service, and West Virginia Division of Environmental Protection, in the review of permit applications required for surface coal mining and reclamation operations resulting in the placement of excess spoil fills in the waters of the United States in West Virginia.

Wetlands and Water Quality

1990 National Guidance - Water Quality Standards for Wetlands - assists States in applying their water quality standards regulations to wetlands.

Wetlands and Non-point Source Control

1990 National Guidance: Wetlands and Non-Point Source Control - describes how State non-point source programs can use the protection of existing wetlands and the restoration of previously lost or degraded wetlands to meet the water quality objectives of adjacent or downstream water bodies.


1989 Memorandum of Agreement - establishes the allocation of enforcement responsibilities between EPA and the Corps for Section 404 of the Clean Water Act.
