EPA is proposing to modify the NPDES permit to Alyeska Pipeline Service Co. for the Valdez Marine Terminal, located in Valdez, Alaska. The current permit (reissued October 30, 2012) authorizes discharges from the ballast water treatment plant (Outfall 001) and the sanitary wastewater treatment plant (Outfall 002) to Port Valdez.

Following issuance, Alyeska sought review of the Whole Effluent Toxicity (WET) provisions in the permit as part of the Environmental Appeals process. EPA agreed to modify the permit and is seeking public comments on those modified conditions, which include: removing acute WET testing, removing the lower trigger for chronic toxicity, expanding the chronic WET testing dilution series, modifying the chronic WET testing frequency, and incorporating language regarding sample holding times.

The unmodified final permit as well as the fact sheet and response to comments can be found at:
