Pennsylvania VOC Rules Head for EPA Approval
Published Date: 7/16/2026
Proposed Rule
Summary
The EPA is proposing to approve Pennsylvania’s updated air pollution rules to better control smelly and harmful chemicals called VOCs that cause ozone pollution. This affects certain factories and businesses that must follow new cleaner technology rules to meet air quality standards from 2008 and 2015. Comments on these changes are open until August 17, 2026, and the updates help keep our air fresher without big costs.
Analyzed Economic Effects
5 provisions identified: 3 benefits, 2 costs, 0 mixed.
Interim final determination stays EPA sanctions
Alongside this proposed approval, the EPA issued an interim final determination (IFD) that Pennsylvania's SIP revisions address the deficiencies cited in the EPA's August 16, 2024 disapproval. The IFD stays emission offset sanctions that were set to begin March 16, 2026, and defers the imposition of highway funding sanctions that would have followed on September 16, 2026.
EPA proposes PA RACT SIP approval
The EPA is proposing to approve four Pennsylvania SIP revisions submitted on May 10, 2023; January 20, 2026; February 17, 2026; and April 10, 2026 that certify Reasonably Available Control Technology (RACT) for volatile organic compound (VOC) Control Technique Guidelines (CTG) under the 2008 and 2015 ozone standards. If finalized, certain factories and businesses in Pennsylvania covered by those CTGs must follow the certified RACT/CTG rules to control VOC emissions to meet the 2008 and 2015 ozone NAAQS.
Permit conditions to become federally enforceable
Pennsylvania asked the EPA to incorporate portions of three source-specific redacted permits into the SIP for facilities subject to the CTG for manufacture of high-density polyethylene, polypropylene, and polystyrene resins. The permits proposed for SIP incorporation are for Multiplastic Extrusions Hazelton (Permit 40-00083), Rohm & Haas Co Bristol (Permit 09-00015), and Shell Chemical Appalachia (Permit 04-00740); EPA is also proposing that BASF Monaca's previously approved permit (04-00306) remains sufficient.
EPA found no new RACT technologies
In its review of Pennsylvania's submissions, the EPA states it has not identified any new control technologies that are reasonably available considering technological and economic feasibility for the CTG source categories addressed. The EPA proposes that Pennsylvania's existing and newly adopted rules meet VOC CTG RACT for the 2008 and 2015 ozone NAAQS.
Negative declaration for large petroleum dry cleaners
Pennsylvania reaffirmed a negative declaration that there are no existing Large Petroleum Dry Cleaner facilities in the Commonwealth; the EPA retained the December 14, 2020 negative declaration in its August 16, 2024 reconsideration and Pennsylvania reasserts no sources in this category.

2026-13667 — Minor New Source Review Program Air Permitting Public Participation Requirements for State Implementation Plans
The EPA wants to give states more freedom to decide how much public input is needed when approving small air pollution sources or changes. This means local air agencies can tailor public participation to fit their community’s needs while still protecting air quality. If you’re involved in air permits, watch for comment deadlines and possible virtual hearings this summer!
2026-13263 — Revisions To Establish the Sixth Unregulated Contaminant Monitoring Rule (UCMR 6) for Public Water Systems
The EPA is rolling out the sixth Unregulated Contaminant Monitoring Rule (UCMR 6) to check for new, sneaky chemicals in public drinking water. Big water systems serving 3,300+ people and some smaller ones will test for 30 different contaminants, including certain PFAS and pesticides, to keep our water safe. Comments and feedback are open until late August 2026, and the EPA will host fun online meetings to chat about the plan!
2026-12927 — U.S. Ecology Nevada, Inc. High Mercury Subcategory Wastes Land Disposal Restrictions Variance
The EPA is giving U.S. Ecology Nevada a special green light to handle and dispose of high-mercury waste a bit differently than usual. This means mercury waste treated in Pennsylvania can now be safely sent to U.S. Ecology’s Nevada site for disposal under new rules starting July 27, 2026. This change helps protect people and the environment while keeping mercury waste management efficient and cost-effective.
