Current through Register Vol. 63, No. 10, October 1, 2024

Section 340-250-0100 - Mitigation of Air Quality Impacts

(1) Any measures that are intended to mitigate air quality impacts must be identified and the process for implementation and enforcement of such measures must be described, including an implementation schedule containing explicit timelines for implementation.

(2) Prior to determining that a federal action is in conformity, the federal agency making the conformity determination must obtain written commitments from the appropriate persons or agencies to implement any mitigation measures which are identified as conditions for making conformity determinations. Such written comments shall describe the mitigation measures and the nature of the commitments in a manner consistent with section (1) of this rule.

(3) Persons or agencies voluntarily committing to mitigation measures to facilitate positive conformity determinations must comply with the obligations of such commitments.

(4) In instances where the federal agency is licensing, permitting or otherwise approving the action of another governmental or private entity, approval by the federal agency must be conditioned on the other entity meeting the mitigation measures set forth in the conformity determination, as provided in section (1) of this rule.

(5) When necessary because of changed circumstances, mitigation measures may be modified so long as the new mitigation measures continue to support the conformity determination. Any proposed change in the mitigation measures is subject to the reporting requirements of OAR 340-250-0050 and the public participation requirements of 340-250-0060.

(6) Written commitments to mitigation measures must be obtained prior to a positive conformity determination and all such commitments must be fulfilled.

(7) After the Department revises its SIP to adopt its general conformity rules and EPA approves that SIP revision, any agreements, necessary for a conformity determination will be both state and federally enforceable. Enforceability through the applicable SIP will apply to all persons who agree to mitigate direct emissions and indirect emissions associated with a federal action for a conformity determination.

[NOTE: This rule is included in the State of Oregon Clean Air Act Implementation Plan as Adopted by the Environmental Quality Commission under OAR 340-200-0040.]
