National Emission Standards for Hazardous Air Pollutants for Polyether Polyols Production; Synthetic Organic Chemical Manufacturing Industry; Epoxy Resins Production and Non-Nylon Polyamides Production; and Petroleum Refineries

The EPA is taking direct final action to amend the national emission standards for hazardous air pollutants (NESHAP) for Polyether Polyols Production; Synthetic Organic Chemical Manufacturing Industry (also known as Hazardous Organic NESHAP, or HON); Epoxy Resins Production and Non-Nylon Polyamides Production; and Petroleum Refineries. For all four of these NESHAP, this direct final rule amends the definition of equipment leaks to add the term "connectors" to the list of equipment that is subject to the equipment leak provisions in those NESHAP. The remainder of this direct final rule corrects referencing errors and several equations which contained printing errors in the final NESHAP for Polyether Polyols Production (hereafter referred to as "subpart PPP"). This direct final rule amends the description of a process change and the description of excess emissions; the requirements pertaining to submission of a request for extension of a compliance date; the storage vessel monitoring requirements; the definition of the terms epoxide, polyether polyol, and Group 2 wastewater stream; the conditions required during performance testing for batch process vents; which compounds are considered to be organic hazardous air pollutants (HAPs) for the purposes of both the maintenance wastewater and the process wastewater requirements; the information requirements for start-up, shutdown, and malfunction reports; the dates on which initial notifications are due; and the reporting requirements for other reports to clarify those requirements. In addition to the direct final rule, in compliance with the Paperwork Reduction Act (PRA), EPA is amending as a final rule the Office of Management and Budget (OMB) approval table to list the OMB control number issued under the PRA for information collection requirements for subpart PPP.
