BG&Es Experience With Cased Carriers On Transmission Lines

“What are we going to do about casings?” became an oft-repeated phase for Baltimore Gas & Electric’s (BG&E’s) pipeline integrity team back in 2007. There were approximately 70 cased crossings identified on the company’s transmission pipe in HCAs regulated by the transmission integrity rule. Pipe inside of casing is covered by the rule, but cannot be indirectly inspected or directly examined.
