DEQ issued a pre-enforcement notice to Grimm's on March 13, 2018 for several permit violations DEQ identified while investigating odor complains in February 2018. Violations include:
- Leachate was being allowed to mix with stormwater in violation of the solid waste requirements.
- Several fires had occurred at the compost facility that Grimm’s had not reported to DEQ as required by the DEQ permit.
- Grimm’s was not measuring moisture content of compost as required by the DEQ permit.
DEQ has asked Grimm’s to take corrective action to prevent these violations from reoccurring and has referred these violations to DEQ’s Office of Compliance and Enforcement for enforcement evaluation.
DEQ is working with Metro and Tualatin Valley Fire and Rescue to identify additional actions for Grimm’s to take to address offsite odor issues.
