WGL Holdings, Inc. Subsidiary Updates Estimated Costs of System Rehabilitation Program in Prince George's County, Maryland

WASHINGTON, April 27 /PRNewswire-FirstCall/ -- Washington Gas Light Company (the company), a wholly-owned subsidiary of WGL Holdings, Inc. (NYSE: WGL), today updated its estimated costs to rehabilitate a portion of its distribution system in Prince George's County, Maryland, which has experienced a higher than usual number of outdoor, underground natural gas leaks.

On April 1, 2005, Washington Gas announced that it will take action to address a significant increase in the number of natural gas leaks in a portion of its distribution system in Prince George's County, Maryland, that resulted from the deterioration of seals located within mechanical couplings that connect sections of distribution mains and service lines. Specifically, Washington Gas expects to address all leaks in the affected area within approximately six months of their being identified, and expects to rehabilitate or replace all other coupled service lines and distribution mains in the affected Prince George's County area by December 2007 even if no leaks are detected.

The costs of this work are expected to be recorded as capital expenditures and are currently estimated to be $87 million. This compares with Washington Gas's originally estimated cost of $75 million, two-thirds of which was initially identified as maintenance expense. The current cost estimate reflects an increase in the number of services expected to be replaced, and an expectation that main replacements will be a larger portion of the total project cost versus encapsulating couplings on mains.

The $87 million estimate does not include any potential costs associated with paving, which could amount to as much as $50 million. The substantial nature of the paving cost estimate is attributable in part to the fact that in 2002, Prince George's County expanded paving requirements and increased related fees. Since that time, Washington Gas has discussed with County officials the County's new paving and permitting requirements, and plans to continue those discussions as this important construction project moves forward.

Washington Gas will request that the Public Service Commission of Maryland (PSC) ratify Washington Gas's decision to account for the encapsulation costs of couplings on mains, currently estimated to be $13 million, as capital expenditures. The company has asked the PSC to review its accounting decision by June 15. Washington Gas is also carefully considering the effect of these expenditures on its ability to earn its allowed returns in Maryland and is evaluating the most appropriate regulatory options to ensure full and timely recovery of, and return on, the amounts expended.

The amounts described above related to the matters in Prince George's County represent estimates that could differ materially from the final amount of costs that are actually incurred.
