Allowable

Wyoming coalbed methane producers could soon be faced with limitations in the allowable volume of CBM water discharges. On May 30, Wyoming State Engineer Patrick Tyrrell met with the Wyoming Coalbed Methane Task Force in Casper to discuss water management strategies to deal with the tremendous volume of CBM water produced in the state.

The Department of Transportation (DOT) has scheduled a public meeting Tuesday in Reston, VA, to explore the possibility of raising the maximum allowable operating pressure (MAOP) for certain natural gas pipelines — a move that would allow more gas to flow through the pipelines and potentially reduce the need for new construction in some cases.

The Department of Transportation (DOT) has scheduled a public meeting next Tuesday in Reston, VA, to explore the possibility of raising the maximum allowable operating pressure (MAOP) for certain natural gas pipelines — a move that would allow more gas to flow through the pipelines and potentially reduce the need for new construction in some cases.

The Department of Transportation ordered Northwest Friday to not exceed 80% of its Maximum Allowable Operating Pressure on the 26-inch line between Sumas and Washougal, WA. The pressure reduction is the DOT’s Office of Pipeline Safety response to a line failure that occurred Thursday afternoon between the Washington cities of Auburn and Sumner (see Daily GPI, May 5), and will continue until Northwest fulfills certain conditions. The pipeline said it had repaired the broken line and restored it to service Sunday, but began implementing the order and completed the pressure cut by Friday night, switching delivery feeds to the neighboring 30-inch line as necessary to maintain required delivery pressures. Northwest estimated it will be limited to a maximum of about 800,000 Dth/d in receipts at Sumas/SIPI until further notice and will cut alternate gas there exceeding 800,000 Dth/d, and primary gas if necessary. “Based upon customer activity over the weekend, we do not expect customers having primary firm capacity through Sumas/SIPI to be affected,” it said. Due to warmer Pacific Northwest weather and lower customer loads, no service cuts had been made as of late Monday afternoon, a spokeswoman said.

Tennessee said it was ceasing enforcement Tuesday of a Balancing Party’s Maximum Allowable Volume.

Florida Gas Transmission has reduced the Maximum AllowableOperating Pressure (MAOP) of its 22-inch mainline downstream ofStation 4. As a result, capacity through Station 4 will drop to 160MMcf/d effective today. The pressure cut is in response to a linebreak last month near Station 4 (see Daily GPI, d20000623j.html”>June23), a spokesman said. FGT still had an Overage Alert Day noticeissued last Wednesday (see Daily GPI, July13) in effect Monday until further notice.
