Environmental Alert
(by Lisa Bruderly)
Yesterday, the U. S. Environmental Protection Agency (EPA) and the U. S. Army Corps of Engineers (Corps) fulfilled the Trump administration’s promise to repeal and replace the Obama administration’s Clean Water Rule (CWR) by publishing the final Navigable Waters Protection Rule (NWPR) in the Federal Register (85 Fed. Reg. 22250). The NWPR (yet again) redefines the scope of waters that are regulated under the Clean Water Act (CWA) by revising the definition of “waters of the United States” (WOTUS) in 12 federal regulations (see January 31, 2020 Alert for details and discussion of anticipated effect of the NWPR).
As expected, the NWPR’s WOTUS definition is much narrower and will federally regulate fewer waters than the CWR. The Rule also clarifies the scope of WOTUS in greater detail than the pre-2015 definition, which is currently in effect. The Rule consolidates jurisdictional waters into four categories: (1) territorial seas and navigable-in-fact waters; (2) tributaries; (3) lakes, ponds and impoundments of jurisdictional waters; and (4) adjacent wetlands. It includes 16 definitions and 12 exclusions, as compared to the five definitions and two exclusions in the pre-2015 definition, including, for the first time, definitions to clarify the prior converted cropland and waste treatment system exclusions. The Rule categorically excludes, among other things, ephemeral streams and ditches without perennial or intermittent flow. In addition, missing from the NWPR is any reference to the significant nexus test.
Practical Impact of the NWPR will be State-Specific
The practical impact of the Rule for industry, developers, agriculture and others will vary from state to state. The NWPR’s effect is likely less in states with very inclusive definitions of state-regulated waters (e.g., Pennsylvania) than in states with narrower definitions of the same. …
