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 t= o 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 compresso= r have exceeded capacity on a regular basis. With Clay Basin shut in, Northwest's balancing flexibility will be significantly impaired. Northwes= t 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 b= y 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.
