Chapter 3745-18 of the Ohio Administrative Code (OAC) contains the requirements for the prevention of emissions of sulfur dioxide into the atmosphere from fuel-burning and process equipment. The rules are part of Ohio’s State Implementation Plan (SIP) for the attainment and maintenance of the National Ambient Air Quality Standards (NAAQS) as required by the Clean Air Act.
Why are these rules being sent out for Early Stakeholder Outreach?
The first step in the rule-making process is for the Ohio Environmental Protection Agency (EPA) to identify that a rule needs to be amended, rescinded, or created. 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.
What changes are being considered?
Ohio EPA will be performing a general review of the rules in this chapter to fulfill the requirements of Ohio Revised Code (ORC) 106.03 (5-year review). Ohio EPA anticipates that changes will involve the addition of emission limitations for the Muskingum River nonattainment area necessary to attain and maintain compliance with the 2010 1-hour SO2 NAAQS and updates to reference materials. Ohio EPA will also review facility-specific information and remove facilities and emission units that are permanently shut down and are no longer subject to regulation under these rules.
Who will be regulated by these rules?
The rules in OAC Chapter 3745-18 are applicable to sources that emit sulfur dioxide, including, but not limited to, fuel-burning equipment, stationary engines, and process equipment.
What is the rulemaking schedule?
Upon completion of the Early Stakeholder Outreach portion of this rulemaking, Ohio EPA will make any changes necessary to the rule language and make a draft of the rule language available to the public for a 30-day review.
