Title: National Emission Standards for Hazardous Air Pollutants for the Polyether Polyols Production Industry | |
Abstract:
This action will address the agency’s technology review of the National Emission Standards for Hazardous Air Pollutants (NESHAP) for the Polyether Polyols (PEPO) Production industry (40 CFR part 63 subpart PPP). The PEPO NESHAP was promulgated pursuant to section 112(d) of the Clean Air Act (CAA) on June 1, 1999, and most recently, the agency conducted its residual risk and technology review (RTR) of the PEPO NESHAP on March 27, 2014. The PEPO NESHAP applies to major sources and regulate hazardous air pollutant (HAP) emissions resulting from the production of chemical products formed by the reaction of ethylene oxide, propylene oxide or other cyclic ethers with compounds having one or more reactive hydrogens. The HAP emission sources at PEPO production facilities include process vents, storage vessels, equipment leaks, wastewater, and heat exchange systems. The HAP emitted by the facilities producing polyether polyols include, but are not limited to, ethylene oxide, propylene oxide, hexane, and toluene. This action will implement the technology review requirements of CAA section 112(d)(6). CAA section 112(d)(6) requires the EPA to review and revise the NESHAP as necessary, taking into account developments in practices, processes and control technologies, no less often than every 8 years. The agency also plans to conduct a residual risk assessment under CAA section 112(f)(2) to consider risks from the polyether polyols production source category during its review. |

Statement of Need: The EPA has a mandatory duty under CAA section 112 to, at least every 8 years, review, and revise as necessary (taking into account developments in practices, processes, and control technologies), its NESHAP promulgated under this section of the CAA. This action will address the EPA’s mandatory obligation to conduct this review for the PEPO NESHAP. Additionally, the EPA has identified ethylene oxide (EtO) emissions from the polyether polyol source category as contributing to potential elevated cancer risks in some areas of the country. This action will address EtO emissions from the source category. |
|||||||||
Summary of the Legal Basis: Clean Air Act section 112, 42 U.S.C. 7412, provides the legal framework and basis for regulatory actions addressing emissions of hazardous air pollutants from stationary sources. CAA section 112(d)(6) requires EPA to review, and revise as necessary, emission standards promulgated under CAA section 112(d) at least every 8 years, considering developments in practices, processes, and control technologies. Additionally, the EPA is conducting a discretionary residual risk assessment under CAA section 112(f)(2) to address unacceptable risks from the polyether polyols production source category. |
|||||||||
Alternatives: EPA is evaluating various options for reducing HAP emissions under the NESHAP, such as emissions control equipment, reducing fugitive emissions, and monitoring. |
|||||||||
Anticipated Costs and Benefits: The anticipated costs and benefits of the action are to be determined. The total capital costs, total annualized costs, and total value of monetized health benefits are all expected to be less than $100 million. |
|||||||||
Risks: The EPA is conducting a discretionary residual risk assessment in this action under CAA section 112(f)(2) to address unacceptable potential cancer risks from the polyether polyols production source category. |
