The MS4 permit reissued to the 13 co-permittees of the Clackamas County Group in March was not considered final as a result of an appeal filed by Clackamas County Water Environment Services (WES). WES and DEQ signed a settlement agreement addressing the issues identified in the appeal to avoid a contested case hearing.
As part of the settlement, DEQ agreed to revise several permit conditions, reissue the MS4 permit (and Permit Evaluation Report), and public notice the revised MS4 permit prior to reissuance.
The revised MS4 permit is out for public comment until Friday, January 13, 2012. You can view the permit by visiting the DEQ website here:

Oregon City's Stormwater Management Plan and Monitoring Plan will be revised to reflect new permit requirements upon issuance of the new permit.
