OAR 340-222-0041
Source Specific Annual PSEL
(1)
For sources with potential to emit less than the SER that request a source specific PSEL, the source specific PSEL will be set equal to the generic PSEL level.(2)
For sources with potential to emit greater than or equal to the SER, the source specific PSEL will be set equal to the source’s potential to emit, netting basis or a level requested by the applicant, whichever is less, except as provided in section (3) or (4).(3)
The initial source specific PSEL for PM2.5 for a source that was permitted on or before May 1, 2011 with potential to emit greater than or equal to the SER will be set equal to the PM2.5 fraction of the PM10 PSEL in effect on May 1, 2011.(a)
Any source with a permit in effect on May 1, 2011 is eligible for an initial PM2.5 PSEL without being otherwise subject to OAR 340-222-0041 (Source Specific Annual PSEL)(4).(b)
For a source that had a permit in effect on May 1, 2011 but later needs to correct its PM10 PSEL that was in effect on May 1, 2011 due to more accurate or reliable information, the corrected PM10 PSEL will be used to correct the initial PM2.5 PSEL.(A)
Correction of a PM10 PSEL will not by itself trigger OAR 340-222-0041 (Source Specific Annual PSEL)(4) for PM2.5.(B)
Correction of a PM10 PSEL could result in further requirements for PM10 in accordance with all applicable regulations.(c)
If after establishing the initial PSEL for PM2.5 in accordance with this rule and establishing the initial PM2.5 netting basis in accordance with OAR 340-222-0046 (Netting Basis), the PSEL is more than nine tons above the netting basis, any future increase in the PSEL for any reason would be subject to 340-222-0041 (Source Specific Annual PSEL)(4).(4)
If an applicant wants an annual PSEL at a rate greater than the netting basis, the applicant must, consistent with OAR 340-222-0035 (General Requirements for Establishing All PSELs):(a)
Demonstrate that the requested increase over the netting basis is less than the SER; or(b)
For increases equal to or greater than the SER over the netting basis, demonstrate that the applicable Major NSR or State NSR requirements in OAR 340 division 224 have been satisfied, except that an increase in the PSEL for GHGs is subject to the requirements of NSR specified in 340-224-0010 (Applicability, General Prohibitions, General Requirements and Jurisdiction)(1)(c) only if the criteria in 340-224-0010 (Applicability, General Prohibitions, General Requirements and Jurisdiction)(1)(c) are met.(5)
If the netting basis is adjusted in accordance with OAR 340-222-0051 (Actual Emissions)(3), then the source specific PSEL is not required to be adjusted.(6)
For sources that meet the criteria in subsections (a), (b) and (c), the requirements of OAR 340-222-0041 (Source Specific Annual PSEL)(4) do not immediately apply, but any future increase in the PSEL greater than or equal to the de minimis level for any reason is subject to OAR 340-222-0041 (Source Specific Annual PSEL)(4).(a)
A PSEL is established or revised to include emissions from activities that both existed at a source and were defined as categorically insignificant activities prior to April 16, 2015;(b)
The PSEL exceeds the netting basis by more than or equal to the SER solely as a result of a revision described in subsection (a); and(c)
The source would not have been subject to Major NSR or Type A State NSR under the applicable requirements of division 224 prior to April 16, 2015 if categorically insignificant activities had been considered.
