Abstract

ABSTRACT Port Valdez is an important fishery resource area located at the proposed terminus of a 48 inch diameter, 800 mile, crude oil pipeline system. This terminus facility will provide for the transfer of crude oil to large oil tankers for shipment to the “lower 48” and will also provide for the treatment of oily ballast water from incoming vessels. The degree of treatment required by State and Federal agencies will limit the treated effluent water to 10 mg/1 total oil content. This is considered to be as stringent a requirement as exists for a similar facility anywhere in the world and was imposed upon the industry to ensure maximum protection of marine life. The treatment facility will consist of primary gravity separation, secondary dissolved-air flotation with the addition of chemicals and an outfall/diffuser system terminating in Port Valdez at a depth greater than 100 feet.
