340-218-0170 Minor Permit Modifications (1) Criteria: (a) Minor permit modification procedures may be used only for those permit modifications that: (A) Do not violate any applicable requirement; (B) Do not involve significant changes to existing monitoring, reporting, or recordkeeping requirements in the permit; (C) Do not require or change a case-by-case determination of an emission limitation or other standard, or a source-specific determination for temporary sources of ambient impacts, or a visibility or increment analysis; (D) Do not seek to establish or change a permit term or condition for which there is no corresponding underlying applicable requirement and that the source has assumed to avoid an applicable requirement to which the source would otherwise be subject. Such terms and conditions include: (i) A federally enforceable emissions cap assumed to avoid classification as a Title I modification; and (ii) An alternative emissions limit approved pursuant to OAR 340-244-0100 through 340-244-0180. (E) Do not increase emissions over the PSEL; (F) Are not Title I modifications; and (G) Are not required by OAR 340-218-0180 to be processed as a significant modification. (b) Notwithstanding subsection (1)(a), minor permit modification procedures may be used for permit modifications involving the use of emissions trading and other similar approaches, to the extent that such minor permit modification procedures are explicitly provided for in the Oregon SIP or in applicable requirements promulgated by the EPA. (2) Minor permit modification procedures. A minor permit modification will be made by DEQ consistent with the following: (a) Application. An application requesting the use of minor permit modification procedures must meet the requirements of OAR 340-218-0040(3), must be submitted on forms and electronic formats provided by DEQ, along with the applicable fees, and must include the following additional information: (A) A description of the change, the change in emissions resulting from the change, and any new applicable requirements that will apply if the change occurs; (B) The source's suggested draft permit; (C) Certification by a responsible official, consistent with OAR 340-218-0040(6), that the proposed modification meets the criteria for use of minor permit modification procedures and a request that such procedures be used; and (D) Completed forms for DEQ to use to notify the EPA and affected states as required under OAR 340-218-0230. (b) EPA and affected state notification. Within five working days of receipt of a complete minor permit modification application, DEQ will meet its obligation under OAR 340-218-0230(1)(a) and (2)(a) to notify the EPA and affected states of the requested permit modification. DEQ promptly will send any notice required under OAR 340-218-0230(2)(b) to the EPA; (c) Timetable for issuance. DEQ will not issue a final permit modification until after the EPA's 45-day review period or until the EPA has notified DEQ that the EPA will not object to issuance of the permit modification, whichever is first, although DEQ can approve the permit modification prior to that time. Within 90 days of DEQ's receipt of an application under minor permit modification procedures or 15 days after the end of the EPA's 45-day review period under OAR 340-218-0230(3), whichever is later, DEQ will: (A) Issue the permit modification as proposed for only those conditions that will change; (B) Deny the permit modification application; (C) Determine that the requested modification does not meet the minor permit modification criteria and must be reviewed under the significant modification procedures; or (D) Revise the draft permit modification and transmit to the EPA the new proposed permit modifications as required by OAR 340-218-0230(1). (d) Source's ability to make change. The source may make the change proposed in its minor permit modification application immediately after it files an application. After the source makes the change, and until the permitting authority takes any of the actions specified in paragraphs (2)(c)(A) through (C), the source must comply with both the applicable requirements governing the change and the draft permit terms and conditions. During this time period, the source need not comply with the existing permit terms and conditions it seeks to modify. However, if the source fails to comply with its draft permit terms and conditions during this time period, the existing permit terms and conditions it seeks to modify may be enforced against it; (e) DEQ may initiate enforcement if the modification has been initiated and does not meet the minor permit modification criteria; (f) Permit shield. The permit shield under OAR 340-218-0110 does not extend to minor permit modifications.
