Re: Additional Site Information At Side-Tap Location Application for a Pipeline Right-of-Way Proposed 8.625-inch O.D. Natural Gas/Condensate Pipeline From West Cameron Block 5$9, OCS-G-5352, Platform A To an existing side tap in West Cameron Block 566, OCS-G-5352, Texas Eastern Transmission Corporation 20-inch O.D. Pipeline Offshore Louisiana, Gulf of Mexico

Dear Ms. Williams:

You and Alex Alvarado have requested certain .information for use in evaluating the referenced permit application; we understand this information might affect decisions regarding our request to avoid burial of our pipeline in the portion of the route traversing water less than 200 f t . deep, and regarding methods used to achieve required cover at the tie-in.

We submit the attached sketch,.just received from Subsea International Diving; Subsea is conducting pre-lay inspections for us now at several locations. The sketch shows that:

1) Since the 20" TETCO pipeline was installed, the burial excavation has filled in to within 3 f t . of the natural bottom elevation. (The natural bottom was measured as -198 f t . , and the bottom over the valve assembly was measured at 1 f t . below the elevation of the valve guard, which was -200 ft. )

2) The top of the valve, at approximately -206 f t . , has about 5 f t . of cover; the gear box (not shown) then has about 4' of cover.

The divers reported that the bottom is "sugar" sand, which requires constant suction pumping in order to keep any excavation open. The valve guard shown, according to TETCO, was installed with the pipeline to protect the valve assembly from the jet sled and from damage while passing over the lay stinger when the line was installed. The divers did not report strong currents or sediment movement.
