all shippers letter # 02 - 033
date : 3 / 15 / 02
time : 11 : 00 a . m . mst
subject : system operations
the purpose of this letter is to inform northwest ' s shippers of how it
intends to deal with the upcoming maintenance announced by questar pipeline
at clay basin and by transwestern pipeline at its la plata facilities .
questar pipeline has announced it will shut in its clay basin facility from
april 2 , 2002 through april 15 , 2002 and will then perform withdrawal tests
on april 16 and 17 , 2002 . during this time northwest will have no access to
clay basin . additionally , transwestern pipeline has announced that its la
plata compressor facilities will be shut in from april 2 through april 5 ,
2002 , and will accept no deliveries from northwest pipeline .
during the month of march north flow volumes through the kemmerer compressor
have exceeded capacity on a regular basis . with clay basin shut in ,
northwest ' s balancing flexibility will be significantly impaired . northwest
will have no place to inject excess gas south of kemmerer and as a result
cannot physically accommodate overscheduled volumes .
if north flow volumes continue to exceed kemmerer capacity during the
questar and transwestern maintenance , northwest will take the following
steps to maintain the reliability and integrity of its system : reduce line
pack on the south end of its system prior to the maintenance ; cut
north - flowing alternate gas at compressor station cut points from la plata
to meacham as necessary to mitigate high line pressures or overscheduling
through kemmerer ; take all necessary steps to ensure that gas deliveries
from receipt points south of the meacham compressor closely approximate
confirmed nominations ; entitle for undertakes or overtakes , as appropriate ;
and finally , if required , northwest will issue operational flow orders .
if net scheduled volumes north through northwest ' s kemmerer compressor do
not exceed physical capacity , northwest will have much greater flexibility
during the clay basin and transwestern shut - ins . northwest ' s customers can
help themselves and reduce the likelihood that kemmerer will overschedule by
securing adequate gas from canadian suppliers or by using their jackson
prairie storage during this work .
northwest will make every effort to reduce the impact on its customers of
the clay basin and transwestern shut - ins and will be monitoring the
situation closely . northwest will take every opportunity to relax system
restrictions in later cycles if north flow volumes moderate . northwest is
confident that if its customers respond prudently , the impact of the
transwestern and questar maintenance will be greatly reduced .
