The U.S. EPA will put on hold a number of regulations that were issued in the final months of the Obama administration, including implementation plans for reducing various pollutants and new guidelines for air modeling. The move is consistent with a regulatory freeze ordered by the Trump administration Jan. 23.
According to a Jan. 25 notice, the EPA will delay the implementation of industry regulations published in the Federal Register between Oct. 28, 2016, and Jan. 17, 2017. The order targets 30 regulations that had yet to become effective and will put them on hold until March 21.
The agency explained that the order is in response to the new administration's request to postpone the effective date of all regulations that had been published in the Federal Register but not yet taken effect.
A number of states will see implementation plans stalled for several different pollutants including ozone, particulate matter, volatile organic compounds and sulfur dioxide. The order was signed by Acting Administrator Catherine McCabe, who is leading the EPA while Congress mulls the approval of Trump administration nominee Scott Pruitt.
