In 1985, about 405 feet of pipeline was added to the pipeline at MP 200.
Below is the coupon (piece cut out) by T.D. Williamson (a company noted for it skills in working on pipelines while they still contain product and pressure) who did the hot-tap – made this cut into a 30″ pipe for the system used to equalize the pressure between the mainline pipe and the bypass pipe. After the hot tap a valve or another piece of pipe is welded to the cut out hole
Size – 6″ x 5 1/4″ with 1 1/4″ hole in center; 1985 [BFH]
