3. QUALITY (Continued)


(d) Within two business days after resolving a gas quality

problem, Transporter will post to its Designated Site: a

description of the problem, the receipt point, the receipt point

operator, the action required, the action taken, and the date and

time that the problem was resolved.



3.6 Gas Analysis Equipment. If Transporter, in its reasonable

judgment, determines that any additional or modified Gas analysis or

control equipment is needed to accurately monitor the quality of Gas

received at an existing Receipt Point and control the receipt of Gas

failing to conform to the applicable quality specifications, then the

Shipper(s) desiring to nominate at such Receipt Point will cause the

interconnecting party at such Receipt Point to install such necessary

additional or modified equipment.


Unless otherwise mutually agreed, if Transporter installs such

additional or modified Gas analysis or control equipment, the

interconnecting party will provide a contribution in aid of construction

to Transporter for all actual costs incurred by Transporter, and

reimburse Transporter for any related income taxes. The related income

taxes will be the difference between Transporter's current federal and

state income tax liability resulting from the contribution in aid of

construction and the present value of Transporter's future tax benefits

resulting from tax depreciation on such facilities, grossed-up for

income taxes. The cash flow discount factor for the present value

calculation will be the most recent weighted cost of capital percentage

specifically approved by the Commission for deriving Transporter's

Recourse Rates.
