last time I looked OR didn’t have a limit on ethanol!!!
if I recall correctly they started out with 5000ppm as recommended here https://www.oregon.gov/oha/ph/preventionwellness/marijuana/documents/oha-8964-technical-report-marijuana-contaminant-testing.pdf
but the CO2 guys were failing so they explicitly removed the limit on ethanol
based on 333-007-0410 there does not appear to be a limit currently (2017 rules).
