Clean Water Act

The federal Clean Water Act (CWA) is the main piece of federal legislation that protects the Nation's waters. Within the CWA, there are a number of sections that specifically address protection or regulation of wetlands. For example, Section 303 addresses water quality standards; Section 401 includes 401 Certification—to condition permits; Section 402 addresses the National Pollutant Discharge Elimination System (NPDES); and Section 404 includes the dredge and fill permitting program as well as State Assumption.

On Wednesday, March 25, 2014, the US Environmental Protection Agency and the US Army Corps of Engineers released the official draft rule to clarify jurisdiction over streams and wetlands. The Association of State Wetland Managers (ASWM) has been following the rulemaking process for more than two years, and has been actively involved with other organizations in interpreting the proposed clarifications and their implications for managing wetlands, streams, floodplains and water quality.

The Clean Water Act was weakened by the US Supreme Court after the split decision known as the Rapanos and Carabell Decision in 2006, which followed another complex debate known as the SWANCC Decision in 2001. The intent of the proposed rule is to clarify jurisdiction for the protection of the nation’s water resources in response to multiple requests from multiple sectors, including the agricultural community, consultants, regulators, developers, natural resource managers and conservation groups.

In addition to publishing the proposed rule on Clean Water Act jurisdiction, EPA and the Army Corps also published an interpretive rule “regarding the Applicability of the Exemption from Permitting under Section 404(f)(1)(A) of the Clean Water Act to Certain  Agricultural Conservation Practices” that can be found here.

Clean Water Act Guidance

In 2011, the U.S. EPA and the U.S. Army Corps of Engineers developed draft guidance for determining whether a waterway, water body, or wetland is protected by the Clean Water Act. This guidance would have replaced previous guidance to reaffirm protection for critical waters. It was also intended to provide clearer, more predictable guidelines for determining which water bodies are protected by the Clean Water Act. The Agencies' Joint draft guidance was never finalized due to multiple requests from stakeholders to issue a rulemaking instead of guidance. The proposed rule described in the section above is the result of that effort to develop the requested rule. For a link to the 2011 Proposed Guidance, click here.

Setting the Record Straight on Waters of the US
Monday, 07 July 2014 00:00

By Nancy Stoner – EPA Connect – July 7, 2014

There’s been some confusion about EPA and the Corps’ proposed “Waters of the U.S.” rule under the Clean Water Act, especially in the agriculture community, and we want to make sure you know the facts.
We know that we haven’t had the best relationship with the agriculture industry in the past, but that doesn’t mean we aren’t and we can’t do better.  We are committed to listening to farmers and ranchers and in fact, our proposed rule takes their feedback into account. The rule keeps intact all Clean Water Act exemptions and exclusions for agriculture that farmers count on. But it does more for farmers by actually expanding the list of up-front exemptions. We worked with USDA’s Natural Resource Conservation Service and the Army Corps of Engineers to exempt 56 additional conservation practices. These practices are familiar to many farmers, who know their benefits to business, the land, and water resources. For full blog post, click here.

EPA, Army Corps Extend Comment Period For Rule Clarifying Clean Water Act Jurisdiction
Tuesday, 10 June 2014 00:00

By Amena H. Saiyidi – House Committee on Small Business – June 10, 2014

The Environmental Protection Agency and the U.S. Army Corps of Engineers confirmed that the public has until Oct. 20 to comment on a proposed rule that would clarify Clean Water Act jurisdiction over the nation's waters and wetlands. The agencies said June 10 that they are granting the 90–day extension from the initial July 21 date in response to numerous requests, including letters from state environmental officials, industry groups and Republican lawmakers. After a private meeting with several Western governors, EPA Administrator Gina McCarthy told reporters June 10 that some of the governors raised concerns about the proposed rule. “There's a lot of concern among agricultural interests in their states and what the industry has read into it,” she said. “We need some time to get out there and, if need be, write the rule in a way so the intent is understood.” The proposed “Waters of the United States” rule, which the EPA published April 21, would bring under federal jurisdiction all tributaries of streams, lakes, ponds and impoundments, as well as wetlands that affect the chemical, physical and biological integrity of larger, navigable downstream waters (79 Fed. Reg. 2,218); (77 DER A-13, 4/22/14). For full article, click here.
