Adopted Rule

Administrative Order No. DEQ 9-2016
Filed and Effective: Aug. 18, 2016
See Oregon Bulletin October 2016

Aron Borok, 503-229-5050 

DEQ is proposing rules to revise Oregon’s water quality standards for bacteria to protect people who recreate in coastal waters. Exposure to high levels of bacteria from swimming and other full immersion water contact recreation is associated with increased gastrointestinal illness.
In addition to revising the bacteria criteria for coastal recreation waters, DEQ also will clarify where freshwater and coastal recreation and shellfish harvesting uses occur and, therefore, where the different bacteria criteria (E. coli, enterococcus, or fecal coliform) apply. DEQ also is proposing to change the averaging period for the E. coli criterion from 30 days to 90 days.
The Oregon Health Authority’s Oregon Beach Monitoring Program is simultaneously engaging in a process to adopt a bacteria level that it will use to issue beach advisories. This Beach Action Value is not part of Oregon’s regulatory water quality standards under the Clean Water Act. More information about the BAV adoption is available on OBMP’s webpage.
