Water Quality Permits

What permit holders need to know

DEQ requires permit holders in Oregon to monitor for various toxic pollutants and uses the results to determine if the permit holder’s discharge is likely to cause or contribute to violations of Oregon’s water quality criteria.
 
In order to streamline the receipt and analysis of this data, DEQ has developed an Electronic Data Delivery system.  Under EDD, permit holders provide DEQ with toxics monitoring data according to a standard format.  The DEQ lab then reviews the data before providing it to DEQ permit staff.
