Net Air Quality Benefit Emission Offsets: Sources in a Designated Area Impacting Other Designated Areas
(1)
When directed by the Major and State NSR rules, the owner or operator of a source locating outside, but impacting any designated area other than an attainment or unclassified area must meet one of the following requirements:(a)
Obtain offsets sufficient to reduce impacts to less than the Class II SIL at all receptors within the designated area as demonstrated using an air quality analysis under OAR 340 division 225; or(b)
Meet the following Net Air Quality Benefit requirements for the designated area that is impacted by the source, as applicable:(A)
For sources subject to Major NSR for the pollutant for which the area is designated:(i)
A source impacting a sustainment area must meet the requirements of OAR 340-224-0045 (Requirements for Sources in Sustainment Areas)(2);(ii)
A source impacting a nonattainment area must meet the requirements of OAR 340-224-0050 (Requirements for Sources in Nonattainment Areas)(2)(b);(iii)
A source impacting a reattainment area must meet the requirements of OAR 340-224-0050 (Requirements for Sources in Nonattainment Areas)(2)(b), treating the reattainment pollutant as a nonattainment pollutant for that rule; or(iv)
A source impacting a maintenance area must meet the requirements of OAR 340-224-0060 (Requirements for Sources in Maintenance Areas)(2).(B)
For sources subject to State NSR for the pollutant for which the area is designated:(i)
A source impacting a sustainment area must meet the requirements of OAR 340-224-0245 (State New Source Review: Requirements for Sources in Sustainment Areas)(1)(b);(ii)
A source impacting a nonattainment area must meet the requirements of OAR 340-224-0250 (State New Source Review: Requirements for Sources in Nonattainment Areas)(2)(b);(iii)
A source impacting a reattainment area must meet the requirements of OAR 340-224-0260 (State New Source Review: Requirements for Sources in Maintenance Areas)(2)(b) treating the reattainment pollutant as a maintenance pollutant for that rule; or(iv)
A source impacting a maintenance area must meet the requirements of OAR 340-224-0260 (State New Source Review: Requirements for Sources in Maintenance Areas)(2)(b).(2)
When directed by the Major and State NSR rules, sources impacting any attainment and unclassified areas, but not directly subject to OAR 340-224-0070 (Prevention of Significant Deterioration Requirements for Sources in Attainment or Unclassified Areas) or 340-224-0270 (State New Source Review: Requirement for Sources in Attainment and Unclassified Areas), must comply with 340-225-0050 (Requirements for Analysis in PSD Class II and Class III Areas)(1) and (2) for each regulated pollutant, other than GHGs, for which emissions will exceed the netting basis by the SER or more due to the proposed source or modification.
