Small Hole Discovered in Ballast Water
Piping for Berth 3
A further inspection on the shore portion of the ballast
water pipe associated with Berth 3 of the Valdez Marine
Terminal has discovered a hole in the pipe wall, and ballast
water has apparently leaked into the ground. The inspection
followed the discovery two weeks ago of a cracked liner
inside the pipe, which increased the possibility of corrosion.
The inspection was part of Alyeskas ongoing corrosion
monitoring program.
The 42-inch pipe carries ballast water, a mixture of
water and crude oil, from tankers at the berth to the Ballast
Water Treatment facility. The hole is approximately one
inch in diameter, and is located on a section of the pipe that
is buried. It is unknown at this time how much oily water
may have leaked. Crude oil makes up about one percent of
ballast water.
Alyeska is developing a plan to remedy the problem, which may include excavation of portions of the ballast water pipe. An inspection of the ballast water piping at Berth 4 was begun this week to determine if there are any corrosion issues there.
Alyeska is focused on completing routine maintenance
on Berth 4 so that operations there can resume as scheduled
in late August. Several maintenance projects are being completed, including the replacement of crude oil loading arms. The shutdown of Berth 3 and 4 is not affecting tanker loading at this time because Berths 1 and 5 remain operational.
All appropriate regulatory agencies have been notified
of the corrosion and the leak in the piping.
Oil/water Spill Contained and Cleaned Up Near West Fire Building in Valdez
A shut valve on the industrial waste water system
(IWW) caused rainwater to back up and overflow through a manhole near the West Fire Water building at the Valdez Marine Terminal. The overflow caused about 1000 gallons of oily water to spill onto the ground around the manhole. Alyeska personnel estimate that about 3 gallons of crude oil was in the water overflow. The event occurred in the evening on Wednesday, August 2nd. An Alyeska employee discovered it during routine rounds in the area.
Once the source of the oil was identified, corrective
measures were undertaken and the spill was stopped immediately. A spill response team immediately started containment and clean up. Sorbents and a vac truck were used for the initial cleanup. The contributing factors are under investigation.
