25.1 Purpose


WNG has joined with other gas enterprises in the formation of and

natural and manufactured gas for the purpose of assisting all

segments of the gas industry in providing adequate, reliable,

safe, economic and environmentally acceptable gas service for the

benefit of gas consumers and the general public.

Article 25 establishes a GRI Funding Unit or Units to be

applicable to WNG's services, except for service under Rate

Schedules FSS, ISS, and PAS, as set forth on Sheet Nos. 6 and 6A

of this FERC Gas Tariff, provided such charge shall not be

applicable to transportation of gas which is subject to a charge

for RD&D by GRI under the effective FERC Gas Tariff of another

interstate pipeline and provided that such charge shall not be

charged twice on the same unit of gas under WNG's rate schedules.
