(2) The board shall consult with the Environmental Quality Commission in adoption and review of best management practices and other rules to address nonpoint source discharges of pollutants resulting from forest operations on forestlands.

(3)(a) Notwithstanding ORS 183.310 (8), upon written petition for rulemaking under ORS 183.390 of any interested person or agency, the board shall review the best management practices adopted pursuant to this section. In addition to all other requirements of law, the petition must allege with reasonable specificity that nonpoint source discharges of pollutants resulting from forest operations being conducted in accordance with the best management practices are a significant contributor to violations of such standards.

(b) Except as provided in paragraph (c) of this subsection, if the board determines that forest operations being conducted in accordance with the best management practices are neither significantly responsible for particular water quality standards not being met nor are a significant contributor to violations of such standards, the board shall issue an order dismissing the petition.

(c) If the petition for review of best management practices is made by the Environmental Quality Commission, the board shall not terminate the review without the concurrence of the commission, unless the board commences rulemaking in accordance with paragraph (e) of this subsection.

(e) If, pursuant to review, the board determines that best management practices should be reviewed, the board shall commence rulemaking proceedings for that purpose. Rules specifying the revised best management practices must be adopted not later than two years from the filing date of the petition for review unless the board, with concurrence of the Environmental Quality Commission, finds that special circumstances require additional time.

(f) Notwithstanding the time limitation established in paragraph (e) of this subsection, at the request of the Environmental Quality Commission, the board shall take action as quickly as practicable to prevent significant damage to beneficial uses identified by the commission while the board is revising its best management practices and rules as provided for in this section.
