GENERAL TERMS AND CONDITIONS (continued)

(i) HDP Problem(s) - Actual Hydrocarbon Liquid Fallout - If

Transporter experiences an HDP Problem and Transporter

determines that a limit on Hydrocarbon Dewpoint is

operationally necessary, Transporter shall post on PASSKEY

Hydrocarbon Dewpoint limits (no lower than 15 degrees F) at

the point where the liquid fallout occurs and then to the

receipt points upstream of that location within the HDP

Segment where the fallout is occurring. If that will not

correct the HDP Problem, Transporter shall apply

Hydrocarbon Dewpoint limits for each HDP Segment

immediately upstream of the HDP Segment where the liquid

fallout occurs up to the nearest Monitoring Point that

satisfies the Hydrocarbon Dewpoint limit. Any such

Hydrocarbon Dewpoint limit shall be applied uniformly to

all receipt points in such HDP Segments. Transporter's

analysis and posting of HDP limits shall not skip over any

HDP Segment between the HDP Problem and the furthermost

upstream HDP Segment to which an HDP limit is posted.

(ii) HDP Problem(s) - Anticipated Hydrocarbon Liquid Fallout -

When Transporter anticipates an HDP Problem under

foreseeable operating conditions and Transporter determines

that Hydrocarbon Dewpoint limits are necessary, Transporter

shall post on PASSKEY, pursuant to the procedures

established in this section below, Hydrocarbon Dewpoint

limits (no lower than 15 degrees F) for the HDP Segment(s)

of Transporter's System required to prevent the anticipated

liquid fallout. Transporter shall make such a posting when

Transporter's analysis of system operating factors

indicates to Transporter a need for a limitation. Such

factors may include, but are not limited to, anticipated

processing plant operation, pressure reduction, flow

patterns, flowing gas temperatures, and Hydrocarbon

Dewpoint temperatures. Hydrocarbon Dewpoint limitations

posted pursuant to this section shall be applied to all HDP

Segment(s) where potential for liquid fallout is

anticipated absent such Hydrocarbon Dewpoint limitation and

to all HDP Segments required to prevent the anticipated

liquid fallout under foreseeable operating conditions,

provided such posting shall not skip over any HDP Segment

between the HDP Problem and the furthermost upstream HDP

Segment to which an HDP limit is posted. Transporter shall

post on PASSKEY an explanation of the basis for the HDP

limit. Upon Shipper's request, Transporter shall provide,

within three Business Days, a written detailed explanation

of the nature and level of the anticipated hydrocarbon

liquid fallout problem, the reasons for its choices of the

posted HDP limit and the affected HDP Segments and the

specific points (i.e., valve, delivery meter,

interconnection facility, etc.), if applicable, where

Transporter anticipated hydrocarbon liquids fallout.

(iii) Transporter shall post HDP limits in a given HDP Segment

only to the extent necessary to prevent or cure an HDP

Problem. Such posted Hydrocarbon Dewpoint limits shall

remain in effect no longer than necessary.
