The 2007 annual report indicated that GLGT repaired five leaks in 2007.

These leak repairs should have also been reported on the annual report.

We have reviewed the circumstances and supporting documents involved in this case, and have decided not to conduct additional enforcement action or penalty assessment proceedings at this time. We advise you to correct the item identified in this letter. Failure to do so will result in Great Lakes Gas Transmission Company, LP. being subject to additional enforcement action.
