NEW! E-Permitting for Air Quality Permits


Our new online permitting system is live. The following materials provide an overview of creating individual accounts for the system, creating and tracking permit applications, and optimizing your experience.

This guidance will show you the types of applications available online, how to upload supplemental materials, how to interact with the assigned engineer, and how to streamline using previous online submissions.

Permit By Rule for Emergency Engine Facilities


Effective September 15, 2016, a newly-promulgated Permit by Rule (PBR) is available OAC 252:100-7-60.6 for facilities that must obtain a permit because of installation of an emergency engine that is subject to a federal standard. Use new Form #100-224 to register under the PBR. Updated September 14, 2016



Revisions to Test Methods, Performance Specifications, and Testing Regulations for Air Emission Sources


Final Rule Signed August 5, 2016: The final "revisions" rule allows source owners and operators of stationary spark ignition internal combustion engines to continue to use Methods 18 and 320 and ASTM D6348-03 to measure VOC but requires reporting of all QA/QC data. See Subpart JJJJ, Section 60.4245(d) and Table 2.

    For Method 18, results from Sections 8.4 and must be reported.

    For Method 320, results from Sections 8.6.2, 9.0, and 13.0 must be reported.

    For ASTM D6348-03, results of all QA/QC procedures in Annexes 1-7 must be reported.

In the preamble to the final "revisions" rule, EPA states that it will revisit the above decision and make a subsequent determination of the appropriateness of the use of Method 320 and/or ASTM D6348 during the first risk and technology review evaluation for stationary spark ignition internal combustion engines. Updated August 30, 2016
