The goals of the Air Monitoring Section are to determine compliance with the ambient air quality standards, to provide real time monitoring of air pollution episodes, to provide data for trend analyses, regulation evaluation and planning, and to provide information to the public on a daily basis concerning the quality of the air in high population areas, near major emission sources and in rural areas.
Asbestos is a naturally occurring mineral fiber, once widely used in building materials and products for its thermal insulating properties and fire resistance. Intact, undisturbed asbestos-containing materials generally do not pose a health risk. These materials may become hazardous and pose increased risk if they are damaged, disturbed in some manner or deteriorate over time and release asbestos fibers into the building's air. A number of building materials and products still in use today contain asbestos. Asbestos remains in use as an acoustic insulator and in thermal insulation, fire proofing, roofing, flooring and other materials. Learn how Ohio EPA regulates emissions and handling of asbestos.

In January 1996, the State of Ohio began a new vehicle emissions testing program, E-Check, designed to identify motor vehicles that emit excessive levels of pollutants into the air. Among the other emissions control options considered by the legislature, E-Check was the most cost-efficient measure to reduce the volatile organic compounds (VOCs) that form ground-level ozone, or smog. The program currently tests cars in seven Ohio counties.
Described below are three types of annual emissions reports a facility may be required to submit. All of these are due April 15 to report the previous calendar year's actual emissions. The report requirements are met using one form to avoid duplicate data entry. The form used and manner in which it is completed and submitted to Ohio EPA is determined by the permitting classification of the facility: Title V; Synthetic Minor; or Non-Title V. More information can be found by clicking on the report type.
All facilities that are required to apply for and obtain an air pollution control operating permit are required to submit an annual emissions report for estimated actual facility wide emissions of particulate matter (PM), sulfur dioxide (SO2), nitrogen oxides (NOx), organic compounds (OC) and lead (Pb). An invoice is generated based on the appropriate fee schedule designated in Ohio law. These reporting requirements are in Ohio Revised Code (ORC) 3745.11 and Ohio Administrative Code (OAC) 3745-78-02.
All facilities classified as Title V or Synthetic Minor for permitting are required to file a complete EIS. This report includes detailed emissions information as well as data about the egress points where the air pollution is released to the air. Pollutants currently required to be reported in the EIS are: NOx, volatile organic compounds (VOC), sulfur dioxide (SO2), lead (Pb), organic compounds (OC), carbon monoxide (CO), ammonia (NH3), PM-Condensable, PM-Filterable, PM less than or equal to 10 microns (PM10) - Filterable, and PM less than or equal to 2.5 microns (PM2.5) - Filterable. Ohio EPA has the authority under OAC rule 3745-15-03 to request and receive the information from regulated entities. EIS information is provided to U.S. EPA to develop an annual criteria and toxic pollutant inventory pursuant to 40 CFR 51.321.
The ES is required of any facility located in a county that is out of attainment for the National Ambient Air Quality Standard (NAAQS) for ozone and emits greater than or equal to 25 tons of VOC or NOx during the reporting year. In general, facilities subject to this requirement must submit actual emissions data for NOx and VOC. The ES is required by Clean Air Act section 182(a)(3)(B) and OAC 3745-24.

Rules and Regulations
Ohio EPA air pollution regulations are located in the Ohio Administrative Code (OAC) in chapters 3745-14 to 3745-26, 3745-31, 3745-71 to 3745-80, 3745-100 to 3745-105, 3745-108, 3745-109, and 3745-112 to 3745-114. Additional chapters are added as needed to address new laws and requirements related to air pollution control.
State Implementation Plan
The Clean Air Act (CAA) requires states to prepare a State Implementation Plan (SIP) for the attainment and maintenance of the National Ambient Air Quality Standards (NAAQS). Ohio's SIP is a set of regulations, policies, and infrastructure designed to assist Ohio is attaining and maintaining the NAAQS for the six criteria pollutants listed in the CAA (ozone, PM2.5, nitrogen oxides, sulfur dioxide, lead and carbon monoxide).
