1/ Annual charge adjustment (ACA) as specified by the Commission and

subject to § 17 of the General Terms and Conditions of Part 1 of this tariff.

2/ The SSXP charges are applicable to Rate Schedule T-1 and T-2 service

made possible by capacity created through Questar's Southern System Expansion

approved in Docket No. CP05-5-000.

3/Released capacity may be sold at a volumetric rate. Shippers

releasing capacity on a volumetric basis must specify a rate between the

maximum and minimum volumetric rate stated on this Statement of Rates and

notify Questar of the criteria by which bids are to be evaluated. Short-term

capacity releases for a term of one year or less are not subject to the

maximum rate limit.

4/Pipeline usage charges are applicable to transportation services that

are released at a volumetric rate and will be billed according to § 18.2 of

the General Terms and Conditions of Part 1 of this tariff. The GRI surcharge

applicable to a release at a volumetric rate is calculated by multiplying the

applicable GRI charge by 12 months and dividing that number by 365 days.

5/ Short-term capacity releases for a term of one year or less are not

subject to the maximum rate limit.

NOTE: The monthly rates stated on Questar's Statement of Rates may be

converted to a daily rate by multiplying the monthly base tariff rate times

the number of months in the rate period and dividing the result by the number

of days in the rate period. The result is rounded to the fourth decimal

place.
