Consistent with past changes in presidential administrations, on President Trump’s Inauguration Day, White House Chief of Staff Reince Priebus issued a “claw back” memo describing the process of reconsidering previously finalized regulations. Similar to memos issued by President Obama and President Bush, President Trump’s claw back memo speaks to three specific groups of rules:

On December 15, 2016, EPA issued a pre-publication version of new regional haze regulations. The Agency’s regional haze program regulates emissions affecting visibility in national parks, or “Class I” areas. EPA promulgated the regulations in 1999 with the goal of achieving natural visibility conditions by 2064. Under the program, states must create plans to control visibility-impairing emissions, and must update these plans every “planning period” of ten years.  The new regulations are intended to apply to the second planning period, but will become effective 30 days after the recently released rule is published in the Federal Register, which is scheduled for January 10th.

On December 16, 2016, President Obama signed the Water Infrastructure Investment for the Nation Act (WIIN) (S. 612).  As one of the last pieces of legislation by Congress this session, the Act gives the Environmental Protection Agency (EPA) authority to approve state permitting programs for coal combustion residuals units (CCR units).  The Act also affects other areas of water resources, ranging from the remediation of lead piping in Flint, Michigan to studies addressing the California drought.

On November 29, 2016, EPA announced the first ten chemicals for which the Agency will perform a risk evaluation under the Toxic Substances Control Act (“TSCA”), as reformed by the Frank R. Lautenberg Chemical Safety for the 21st Century Act, passed earlier this year.  As part of this review, EPA will evaluate whether the chosen chemicals “present an unreasonable risk of injury to health or the environment.”
