The general stormwater permits applicable to industrial sites near the Columbia Slough and elsewhere in Oregon were issued with numerous errors and omissions last year.  DEQ has corrected the errors relating to sampling and reporting requirements and reissued the general permits.

If these permits apply to you then you will want to check the changes and the new general permits which are now available on the DEQ website as described below.

A summary of the final changes, response to comments and final permits are available on DEQ’s Industrial Stormwater Permits web page.
