On January 6, 2021, the U.S. Environmental Protection Agency (EPA or the Agency) published a final rule, “Strengthening Transparency in Pivotal Science Underlying Significant Regulatory Actions and Influential Scientific Information.” EPA published the proposed rule in April 2018 and followed it with a supplemental notice in March 2020. The final rule establishes how EPA will consider the availability of dose-response data, and it is narrower in scope than both the proposed rule and the supplemental notice, as it is restricted to “those studies that describe the quantitative relationship between the dose or exposure of a pollutant, contaminant, or substance and an effect.” (more…)
On January 5, 2021, the U.S. Army Corps of Engineers (Corps) released a prepublication version of its final rule reissuing and modifying 12 existing Nationwide Permits (NWPs) and issuing four new NWPs. NWPs authorize activities under Section 404 of the Clean Water Act (CWA) and Section 10 of the Rivers and Harbors Act of 1899 when those activities will result in “minimal individual and cumulative adverse environmental effects.” In addition to finalizing 16 NWPs, the rule also changed general conditions and definitions associated with those NWPs. Through this action, the Corps did not reissue or modify the remaining 40 existing NWPs, which will remain in effect until March 18, 2022.
On October 23, 2020, a week of climate discussions by the International Maritime Organization (IMO) Intersessional Working Group on Reduction of Greenhouse Gas Emissions From Ships concluded with draft measures to cut carbon emissions from ships. The new measures would amend the International Convention for the Prevention of Pollution From Ships (MARPOL Convention) and require ships to reduce their carbon intensity as part of IMO’s goal to reduce the carbon intensity of international shipping by 40% by 2030 from 2008 levels. If adopted, the amendments would require new ships to be built so that they are more energy efficient than the Energy Efficiency Design Index (EEDI) baseline. (more…)
On October 22, 2020, the U.S. Environmental Protection Agency (EPA) published a prepublication version of a final rule clarifying the process for existing air pollution sources to determine whether the New Source Review (NSR) permitting program applies to proposed projects. The new rule clarifies and confirms that project emissions accounting can be considered during Step 1 of the two-step NSR applicability test, meaning that both emissions increases and decreases from the proposed modification will be considered. The two steps of the NSR applicability test consist of a first step to determine whether a proposed project will cause a significant emission increase of a regulated NSR pollutant and, if it would, the second step determines if there will be a significant net emission increase of the same regulated NSR pollutant considering all other contemporaneous emissions increases and decreases.
