Overview This Handbook provides advice on compliance with the Section 404(b)(1) Guidelines as part of the environmental review process for a transportation project. Section 404(b)(1) Guidelines of the Clean Water Act prohibits the discharge of dredged or fill materials into waters of the United States@ except when authorized by a permit issued by the U.S. Army Corps of Engineers (Corps). Waters of the United States??also called jurisdictional waters??include many wetlands@ streams@ lakes@ and rivers@ as well as oceans. When issuing permits under Section 404@ the Corps must comply with the Section 404(b)(1) Guidelines. The guidelines define the criteria that must be met in order for the Corps to issue a Section 404 permit. The guidelines were issued by the U.S. Environmental Protection Agency (EPA) and are included in EPA's regulations at 40 CFR Part 230. Federal agencies typically consider the guidelines as one part of an environmental review process that includes compliance with many other laws@ such as the National Environmental Policy Act (NEPA). Therefore@ rather than addressing the Guidelines in isolation@ this Handbook considers the guidelines in the context of the environmental review process as a whole. The Handbook uses a step-by-step approach to illustrate the actions that can be taken throughout the process to lay the groundwork for compliance with the guidelines. It is important to note several points regarding the scope and emphasis of this Handbook: The Handbook focuses on actions that transportation agencies can take in their capacity as project sponsors@ joint lead agencies@ and/or Section 404(b)(1) Guidelines permit applicants. The Handbook focuses on projects that require an individual Section 404(b)(1) Guidelines permit under the Clean Water Act and that involve preparation of an Environmental Impact Statement (EIS) or Environmental Assessment (EA) under NEPA??in other words@ relatively large and complex projects. These projects are the focus of the Handbook because they are the ones that are most likely to involve challenges regarding the application of the guidelines. The Handbook does not address projects that qualify for nationwide or regional general permits. The Handbook focuses on Section 404(b)(1) Guidelines permitting@ rather than covering all forms of Corps permitting equally. The Handbook briefly discusses permits issued by the Corps under Sections 9 and 10 of the Rivers and Harbors Act. The Handbook focuses on the guidelines specifically@ rather than covering all aspects of Section 404(b)(1) Guidelines permitting. The Handbook focuses on the guidelines because of their important role in decisionmaking for complex transportation projects. As context for the discussion of the guidelines@ the Handbook includes background information on other important aspects of Section 404(b)(1) Guidelines permitting@ such as jurisdictional determinations.
