Grimm’s Fuel owns and operates a composting facility at 18850 SW Cipole Road in Tualatin. In 2009 and 2013, Oregon adopted updated composting rules. Grimm’s is operating under a grandfathered pre-2009 permit until DEQ takes final action on a new permit.
DEQ offered a draft permit for public comment on Sept. 30, 2013 and held a public hearing on Oct. 30, 2013. Due to the level of community interest, DEQ extended the public comment period to Nov. 20, 2013. In response to the comments, DEQ made revisions to the draft permit, and issued it on May 1, 2014. Grimm’s appealed the permit. DEQ revised conditions of the permit and initiated an additional public comment period on June 2, 2015. DEQ held a public hearing on the latest draft compost permit on July 8, 2015. DEQ responded to comments received and issued a new compost permit to Grimm’s Fuel on Nov. 20, 2015.
