Division of Air Pollution Control Rules and Laws

The Division of Air Pollution Control (DAPC) develops and enforces rules in the Ohio Administrative Code (OAC). These rules assist the state of Ohio to:

  • Attain and maintain the National Ambient Air Quality Standards (NAAQS) contained in the Clean Air Act
  • Fulfill the requirements set forth by the Ohio General Assembly in Ohio Revised Code (ORC) Section 3704
  • Protect and maintain healthy air quality for the citizens of the state of Ohio

Ohio EPA air pollution control regulations are located in the OAC in chapters 3745-14 to 3745-26, 3745-31, 3745-71 to 3745-73, 3745-77 to 3745-80, 3745-100, 3745-103, 3745-104, and 3745-109 to 3745-114. Additional chapters are added as needed to address new laws and requirements related to air pollution control.

Proposing new rules and amendments to existing rules is a regular activity conducted by Ohio EPA in response to laws passed by the General Assembly and federal rule requirements. The Agency is also required by state law to review its rules at least once every five years to ensure their continued need and relevance.

During the Ohio rule-making process, rules pass through the following four phases: early stakeholder outreach; draft review; proposal to the Joint Committee on Agency Rule Review (JCARR); and final adoption. To view the rules currently in each of these phases, please view the tabs below.

Some of Ohio EPA’s air pollution control regulations are a part of Ohio’s State Implementation Plan (SIP). Rules that are a part of Ohio’s SIP are submitted to U.S. EPA after final promulgation of the rule(s) and then U.S. EPA must in turn take action to approve the rule(s) into Ohio’s SIP. The process of U.S. EPA approval can take up to 18-months after Ohio EPA submits a request, as allowed under CAA Section 110(k). Therefore, often there is a time lag between the effective date of Ohio’s rules and the effective date of approval of those rules as a part of Ohio’s SIP. When a rule(s) that was approved as a part of Ohio’s SIP is amended, Ohio EPA will often submit the amended rule(s) as a revision to the approved Ohio SIP, which U.S. EPA must again take action to approve as a replacement. To find a list of the currently approved SIP rules, and the effective dates of those rules, see 40 CFR 52.1870. As explained above, some of these SIP approved rules will not be the most currently effective rule found on the tab below. You may request specific SIP approved rules not found in the tab below by contacting Ohio EPA DAPC’s Rule Coordinator at paul.braun@epa.ohio.gov or 614-644-3734.

If you would like to receive e-mail notifications regarding opportunities to provide comment regarding important changes to Ohio’s air pollution control rules, please go to Ohio EPA's Customer Support Center, log-in or sign-up to create a new account, and choose "Information on rulemaking activity and regulatory notifications from the Division of Air Pollution Control" from your subscriptions.

The first step in the rule-making process is for Ohio EPA to identify that a rule needs to be amended, rescinded or created. Ohio EPA may also review a rule pursuant to the five-year rule review requirements (ORC 106.03) and determine that the rule should be filed with the Joint Committee on Agency Rule Review (JCARR) as 'no change.'

In response to Executive Order 2011-01K, Ohio EPA has added an additional step to ensure stakeholders are brought into the rule process as early as possible. This additional interested party notification and request for information will allow for early feedback before the rule language has been developed by the Agency.

The following rules are currently undergoing early stakeholder outreach:

  • Stakeholder Input Requested on Rulemaking - OAC Ch. 3745-107, "Affordable Clean Energy Program Rules"
    Ohio EPA is requesting stakeholder input on potential recission of rules in Ohio Administrative Code (OAC) Chapter 3745-107, "Affordable Clean Energy Program Rules." The Affordable Clean Energy rule (ACE), finalized by the United States Environmental Protection Agency on July 8, 2019 (84 FR 32520), consists of emission guidelines for greenhouse gas (GHG) emissions from existing electric utility generating units (EGUs) under Clean Air Act (CAA) section 111(d) that will inform states on the development, submittal, and implementation of state plans to establish performance standards for GHG emissions from certain fossil fuel fired EGUs.

    Ohio EPA is considering rescinding all of the rules in OAC Chapter 3745-107. OAC Chapter 3745-107 was developed to implement federal requirements to establish greenhouse gas performance standards at existing coal-fired EGUs under the ACE Rule {84 FR 32520}. On January 19, 2021 the United States Court of Appeals (USCOA) for the District of Columbia Circuit issued a ruling on USCOA Case #19-1140 vacating U.S. EPA’s ACE Rule. With this vacature, OAC Chapter 3745-107 is not applicable to any sources in the State of Ohio and therefore these rules are no longer necessary.

    Prior to generating draft rule language, Ohio EPA is asking for input/suggestions on the rules from potentially affected parties. Instructions for providing comments and where to submit them are provided in the Stakeholder Input Request. Ohio EPA will be accepting comments on these potential changes through Friday, May 14, 2021.

  • Stakeholder Input Requested on Rulemaking - OAC Ch. 3745-71, "Lead Emission Regulations"
    Ohio EPA is requesting stakeholder input on potential amendments to rules in Ohio Administrative Code (OAC) Chapter 3745-71, "Lead Emission Regulations." The rules in this chapter contain the requirements for ascertaining, defining and measuring ambient air quality related to emissions of lead. Historically, these rules regulated a single lead source in Ohio but the rules specific to this source were previously rescinded due to the permanent shutdown of the lead source. The only remaining rules in this chapter identify the method used to measure ambient air quality and definitions associated with that rule.

    On March 12, 2021 (86 FR 14061), USEPA proposed removing these rules from Ohio’s state implementation plan (SIP). USEPA proposed the removal at the request of Ohio because the facilities specifically regulated by the rules are premanently shutdown and sampling requirements in the rules are duplicated elsewhere in Ohio’s air pollution control rules. Ohio EPA intends to begin the rulemaking process for rescinding these rules from the OAC because once they are removed from Ohio’s SIP, they will no longer be necessary.

    Prior to generating draft rule language, Ohio EPA is asking for input/suggestions on the rules from potentially affected parties. Instructions for providing comments and where to submit them are provided in the Stakeholder Input Request. Ohio EPA will be accepting comments on these potential changes through Thursday, May 13, 2021.

  • Proposal of Amended Rules - State Emergency Response Commission (SERC) Rules
    On behalf of the director of the State Emergency Response Commission (SERC), the Ohio Environmental Protection Agency, Division of Air Pollution Control (DAPC) has proposed amended and no-change rules in Ohio Administrative Code (OAC) Agency 3750 to the Joint Committe on Agency Rule Review (JCARR). The rules in OAC Agency 3750 establish the framework of the State Emergency Response Commission (SERC) and Local Emergency Planning Committees (LEPCs) and establish emergency planning and release reporting reporting requirements to facilities that store hazardous chemicals or extremely hazardous substances or have a spill or release of extremely hazardous substances, CERLA hazardous substances or oil as defined. The list of rules being considered for amendment is included below. DAPC is also recommending certain SERC rules remain necessary, but are without need of change. The list of No-Change rules can be found in the public notice, linked below.

    Ohio EPA will be holding a virtual public hearing on the new rules on Friday, April 23, 2021, at 10:30 a.m. The virtual hearing may be accessed through Ohio EPA’s website at: http://epa.ohio.gov/virtual.

  • Proposal of Amended Rules - OAC Chapter 3745-73, Total Reduced Sulfur Rules
    The Division of Air Pollution Control (DAPC) has proposed amended rules in Ohio Administrative Code (OAC) Chapter 3745-73, "Total Reduced Sulfur Rules" to the Joint Committe on Agency Rule Review (JCARR). The rules in this chapter contain the requirements for the control of emissions of total reduced sulfur from Kraft Pulp Mills. A Kraft Pulp Mill is a wood pulping mill which uses an alkaline sulfide solution containing sodium hydroxide and sodium sulfide (white liquor) in the wood digesting process. These sulfur emissions are precursors to sulfur dioxide and particulate matter for which national ambient air quality standards have been established under the Clean Air Act.

    Ohio EPA will be holding a virtual public hearing on the new rules on Thursday, April 22, 2021, at 10:30 a.m. The virtual hearing may be accessed through Ohio EPA’s website at: http://epa.ohio.gov/virtual.

    Please see the public hearing notice, proposed rule language and the synopsis of changes (linked below) for information on the proposed changes and how to submit comments/attend the hearing.
