For the purpose of OAR 340-210-0200 through 340-210-0250, changes that involve new construction or modifications of sources or air pollution control devices are divided into the following Types:

(1) Type 1 changes include construction or modification of sources or air pollution control devices where such a change meets the criteria in subsections (a) through (f):

(a) Would not increase emissions from the source above the PSEL by more than the de minimis emission level defined in OAR 340-200-0020 for sources required to have a permit;

(b) Would not increase emissions from the source above the netting basis by more than or equal to the SER;

(c) Would not increase emissions from any new, modified, or replaced device, activity or process, or any combination of devices, activities or processes at the source by more than the de minimis levels defined in OAR 340-200-0020;

(d) Would not be used to establish a federally enforceable limit on the potential to emit; and

(e) Would not require a TACT determination under OAR 340-226-0130 or a MACT determination under OAR 340-244-0200; and

(f) Is not required to obtain a permit under OAR 340 division 216.

(b) Would not increase emissions from the source above the netting basis by more than or equal to the SER;

(c) Would not increase emissions from any new, modified, or replaced device, activity or process, or any combination of devices, activities or processes at the source by more than or equal to the SER;

(d) Would not be used to establish a federally enforceable limit on the potential to emit;

(3) Type 3 changes include construction or modification of sources or air pollution control devices where such a change does not qualify as a Type 4 change under section (4) and:

(a) Would increase emissions from the source above the PSEL by more than the de minimis emission level defined in OAR 340-200-0020 before applying unassigned emissions or emissions reduction credits available to the source but less than the SER after applying unassigned emissions or emissions reduction credits available to the source for sources required to have a permit;

(b) Would increase emissions from any new, modified, or replaced device, activity or process, or any combination of devices, activities or processes at the source by more than the SER but are not subject to OAR 340-222-0041(4);

(c) Would be used to establish a federally enforceable limit on the potential to emit; or

(d) Would require a TACT determination under OAR 340-226-0130 or a MACT determination under 340-244-0200.

(4) Type 4 changes include construction or modification of sources or air pollution control devices where such a change or changes would increase emissions from the source above the PSEL, after applying unassigned emissions or emissions reduction credits available to the source, or netting basis of the source by more than the SER.

NOTE: This rule is included in the State of Oregon Clean Air Act Implementation Plan that EQC adopted under OAR 340-200-0040.
