The group's principle activity is to operate and maintain an existing natural gas pipeline, together with ancillary facilities, substitute one or more of the three existing leased compressors with leased compressors of greater horsepower to augment delivery capacity within stated limits on a blanket basis, and undertake self-implementing interstate transportation of natural gas. The group also provides firm and interruptible transportation services on a non-discriminatory, open access basis. The group operates from United States.
