 January 18, 2023: New definition of "waters of the U.S"

The Environmental Protection Agency and U.S. Army Corps of Engineers ("the agencies") are in receipt of the U.S. District Court for the District of Arizona’s August 30, 2021, order vacating and remanding the Navigable Waters Protection Rule (NWPR) in the case of Pascua Yaqui Tribe v. U.S. Environmental Protection Agency. In light of this order, the agencies have halted implementation of the NWPR nationwide and are interpreting “waters of the United States” consistent with the pre-2015 regulatory regime. 

On December 30, 2022, the agencies announced the final "Revised Definition of 'Waters of the United States'" rule. On January 18, 2023, the rule was published in the Federal Registerthe rule will be effective on March 20, 2023. The agencies developed this rule with consideration of the relevant provisions of the Clean Water Act and the statute as a whole, relevant Supreme Court case law, and the agencies’ technical expertise after more than 45 years of implementing the longstanding pre-2015 “waters of the United States” framework. This rule also considers the best available science and extensive public comment to establish a definition of “waters of the United States” that supports public health, environmental protection, agricultural activity, and economic growth. More information about the final rule is available here.

Updates on the Chehalis River Basin Flood Control Zone District Proposal

Applicant's Proposal Description:

The Chehalis River Basin Flood Control Zone District (applicant) is proposing construction of a water retention facility and associated infrastructure on the main-stem Chehalis River south of the Town of Pe Ell, Washington. The facility would have capacity to provide 65,000 acre-feet of temporary flood storage during major floods, and would be constructed with a foundation to allow the future expansion of its water retention capacity. The Chehalis River would flow normally during regular conditions or small flood events. The top of the dam structure would be 1,220 feet long with a maximum structural height of up to 254 feet including 3 to 5 feet of freeboard for safety. The dam is proposed to include a 210-foot-wide emergency spillway, discharging into a 70-foot stilling basin. The applicant also proposes to raise the elevation  of the Centralia-Chehalis Airport levee in Chehalis, Washington.  The levee would be raised 4 to 7 feet, along with raising Airport Road 1,700 feet along the southern extent of the airport. The proposal is in pre-application status.
