Exemptions

(a) Exemptions from the requirements of OAC 252:100-8-34 through 252:100-8-36.2. (1) The requirements of OAC 252:100-8-34 through 252:100-8-36.2 do not apply to a particular major stationary source or major modification if the source or modification is: (A) a nonprofit health or nonprofit educational institution; or (B) major only if fugitive emissions, to the extent quantifiable, are included in calculating the potential to emit and such source is not one of the categories listed in paragraph (C) of the definition of "Major stationary source"; or (C) a portable stationary source which has previously received a permit under the requirements contained in OAC 252:100-8-34 through 252:100-8-36.2 and proposes to relocate to a temporary new location from which its emissions would not impact a Class I area or an area where an applicable increment is known to be violated. (2) The requirements in OAC 252:100-8-34 through 252:100-8-36.2 do not apply to a major stationary source or major modification with respect to a particular pollutant if the owner or operator demonstrates that the source or modification is located in an area designated as nonattainment for that pollutant under section 107 of the Act. Nonattainment designations for revoked NAAQS, as contained in 40 CFR part 81, shall not be viewed as current designations under section 107 of the Act for purposes of determining the applicability of requirements equivalent to those contained in Sections 252:100-8-34 through 252:100-8-36.2 to a major stationary source or major modification after the revocation of that NAAQS is effective. (b) Exemption from air quality impact analyses in OAC 252:100-8-35(a) and (c) and 252:100-8-35.2. (1) The requirements of OAC 252:100-8-35(a) and (c) and 252:100-8-35.2 are not applicable with respect to a particular pollutant, if the allowable emissions of that pollutant from a new source, or the net emissions increase of that pollutant from a modification, would be temporary and impact no Class I area and no area where an applicable increment is known to be violated. (2) The requirements of OAC 252:100-8-35(a) and (c) and 252:100-8-35.2 as they relate to any PSD increment for a Class II area do not apply to a modification of a major stationary source that was in existence on March 1, 1978, if the net increase in allowable emissions of each regulated NSR pollutant from the modification after the application of BACT, would be less than 50 TPY. (3) The requirements of OAC 252:100-8-35(a) and (c) and 252:100-8-35.2 are not applicable with respect to GHGs, as individual pollutants or as an aggregate. (c) Exemption from air quality analysis requirements in OAC 252:100-8-35(c). (1) The monitoring requirements of OAC 252:100-8-35(c) regarding air quality analysis are not applicable for a particular pollutant if the emission increase of the pollutant from a 2024_Oct_AQAC_SC_5_7_8_RUL_Presented 45 October 15, 2024 proposed major stationary source or the net emissions increase of the pollutant from a major modification would cause, in any area, air quality impacts less than the following amounts: (A) Carbon monoxide - 575 μg/m3, 8-hour average, (B) Nitrogen dioxide - 14 μg/m3, annual average, (C) PM2.5 - 0 μg/m3, no exemption available, (D) PM10 - 10 μg/m3, 24-hour average, (E) Sulfur dioxide -13 μg/m3, 24-hour average, (F) Ozone - no de minimis air quality level is provided for ozone, however any net increase of 100 TPY or more of VOC or NOX subject to PSD would require an ambient impact analysis, including the gathering of ambient air quality data, (G) Lead - 0.1 μg/m3, 24-hour 3-month average, (H) Fluorides - 0.25 μg/m3, 24-hour average, (I) Total reduced sulfur - 10 μg/m3, 1-hour average, (J) Hydrogen sulfide - 0.2 μg/m3, 1-hour average, or (K) Reduced sulfur compounds - 10 μg/m3, 1-hour average. (2) The monitoring requirements of OAC 252:100-8-35(c) are not applicable for a particular pollutant if the pollutant is not listed in preceding OAC 252:100-8-33(c)(1). (d) Exemption from monitoring requirements in OAC 252:100-8-35(c)(1)(B) and (D). (1) The requirements for air quality monitoring in OAC 252:100-8-35(c)(1)(B) and (D) shall not apply to a particular source or modification that was subject to 40 CFR 52.21 as in effect on June 19, 1978, if a permit application was submitted on or before June 8, 1981, and the Director subsequently determined that the application was complete except for the requirements in OAC 252:100-8-35(c)(1)(B) and (D). Instead, the requirements in 40 CFR 52.21(m)(2) as in effect on June 19, 1978, shall apply to any such source or modification. (2) The requirements for air quality monitoring in OAC 252:100-8-35(c)(1)(B) and (D) shall not apply to a particular source or modification that was not subject to 40 CFR 52.21 as in effect on June 19, 1978, if a permit application was submitted on or before June 8, 1981, and the Director subsequently determined that the application as submitted was complete, except for the requirements in OAC 252:100-8-35(c)(1)(B) and (D). (e) Exemption from the preapplication analysis required by OAC 252:100-8-35(c)(1)(A), (B), and (D). (1) The Director shall determine if the requirements for air quality monitoring of PM10 in OAC 252:100-8-35(c)(1)(A), (B), and (D) may be waived for a particular source or modification when an application for a PSD permit was submitted on or before June l, 1988, and the Director subsequently determined that the application, except for the requirements for monitoring particulate matter under OAC 252:100-8-35(c)(1)(A), (B), and (D), was complete before that date. (2) The requirements for air quality monitoring of PM10 in OAC 252:100-8-35(c)(1)(B)(i), 252:100-8-35(c)(1)(D), and 252:100-8-35(c)(3) shall apply to a particular source or modification if an application for a permit was submitted after June l, 1988, and no later than December 1, 1988. The data shall have been gathered over at least the period from February l, 1988, to the date the application became otherwise complete in accordance with the provisions of OAC 252:100-8-35(c)(1)(C), except that if the Director determines that a complete and adequate analysis can be accomplished with monitoring data over a shorter period (not to be less than 4 months), the data required by OAC 252:100-8-35(c)(1)(B)(ii) shall have been gathered over that shorter period. 2024_Oct_AQAC_SC_5_7_8_RUL_Presented 46 October 15, 2024 (f) Exemption from BACT requirements and air quality analyses requirements. If a complete permit application for a source or modification was submitted before August 7, 1980 the requirements for BACT in OAC 252:100-8-34 and the requirements for air quality analyses in OAC 252:100-8-35(c)(1) are not applicable to a particular stationary source or modification that was subject to 40 CFR 52.21 as in effect on June 19, 1978. Instead, the federal requirements at 40 CFR 52.21 (j) and (n) as in effect on June 19, 1978, are applicable to any such source or modification. (g) Exemption from OAC 252:100-8-35(a)(1)(B). The permitting requirements of OAC 252:100-8-35(a)(1)(B) do not apply to a stationary source or modification with respect to any PSD increment for nitrogen oxides if the owner or operator of the source or modification submitted a complete application for a permit before February 8, 1988.
