Approval and Promulgation of Air Quality Implementation Plans; Maryland; Direct Final Rule for the Approval of an Alternative Volatile Organic Compound Emission Standard; Withdrawal

Due to adverse comments received, the Environmental Protection Agency (EPA) is withdrawing the August 28, 2017 direct final rule that approved a revision to the Maryland state implementation plan (SIP) to incorporate by reference a Maryland Department of the Environment (MDE) order that establishes an alternative volatile organic compound (VOC) emission standard for National Gypsum Company (NGC) to ensure that it remains a minor VOC source. EPA stated in the direct final rule that if EPA received adverse comments by September 27, 2017, the rule would be withdrawn and not take effect. EPA subsequently received one adverse comment. EPA will address the comment received in a subsequent final action based upon the proposed action also published on August 28, 2017. EPA will not institute a second comment period on this action.
