GENERAL TERMS AND CONDITIONS (Cont'd)
19.8 Critical Day Requirement for Penalties.
A "Critical Day" for transportation and/or storage will be declared by Transporter whenever
Transporter, in Transporter's reasonable discretion, determines (based on criteria such as weather forecasts,
line pack, storage conditions, pipeline pressures, horsepower availability, system supply and demand, and
other operational circumstances) that operating conditions are such that Transporter faces a threat to its
system integrity and/or to Transporter's ability to meet its firm service obligations. With the exception of
(1) failure to interrupt penalties imposed pursuant to Sections 16 and 19 of the General Terms And Conditions
and/or the failure to interrupt provisions of individual rate schedules, (2) OFO penalties imposed pursuant to
the provisions of Sections 17 and 19 of the General Terms And Conditions and/or the OFO provisions of
individual rate schedules, and (3) Daily Delivery Point Scheduling Penalties imposed pursuant to Section 19.5
of the General Terms and Conditions, Transporter will not impose penalties under this Section 19 and under any
rate schedule unless a Critical Day, as defined above, has been declared and is in effect on Transporter's
system. For penalties ascribed for conduct that occurs over a monthly as opposed to a daily period of time,
these monthly penalties will be imposed only if Transporter has declared a Critical Day on any day occurring
in that monthly period.
Except for force majeure events and/or events or conditions which threaten the integrity of
Transporter's system or Transporter's ability to meet its firm service obligations, Transporter will notify
Shippers at least 24 hours in advance on its Internet EBB (1) the effective dates of the Critical Day; (2) the
type of penalties that will be applicable during the Critical Day period; and (3) to the extent applicable,
the Market Areas where penalties will be applied. If due to declaration of a Critical Day, a monthly penalty
becomes applicable, Transporter will notify Shippers by posting on its Internet EBB notice that the monthly
penalty is applicable. Within two weeks of a Critical Day event, Transporter will post information on its EBB
describing the events leading up to the declaration of the Critical Day.
19.9 No Imposition of Multiple Penalties
Transporter will not impose on a Shipper both OFO or failure to interrupt service penalties pursuant to
Sections 17 and 19 of the General Terms and Conditions and Critical Day penalties for the same infraction.
(a) Transporter anticipates that Critical Day penalties will be implemented to impose system
discipline to ensure Transporter's ability to meet its firm service obligations. To the extent Critical Day
penalties are no longer imposing system discipline, such that Transporter's firm service obligations are being
threatened, Transporter can implement an OFO to alleviate conditions threatening the integrity of
Transporter's system. Transporter can also implement an OFO to deal with sudden, unexpected and catastrophic
events on its system.
(b) When reasonably feasible, Transporter will post notices on its EBB advising that if Shippers
take certain specific actions, Transporter may be able to avoid the issuance of a Critical Day, or minimize
the sequential issuance of Critical Days.
