New Report Refutes Claims that Aliso Canyon Natural Gas Facility Is …
September 3, 2016 - storage organizer
Southern California Gas Company (SoCalGas) can accommodate a summer and winter rise direct though a Aliso Canyon gas storage facility, notwithstanding a company’s steady warnings that blackouts could start if Aliso stays offline. This is according to a new news prepared for Food Water Watch and a village organisation Save Porter Ranch.
The report, Critical Review of Aliso Canyon Winter Risk Assessment and Action Plan, by Bill Powers, P.E. of Powers Engineering, finds that as prolonged as existent slackening measures sojourn in place, Aliso Canyon, one of a largest healthy gas storage fields in a western U.S. and site of a largest methane trickle in U.S. history, is not indispensable to pledge possibly summer or winter gas reserve in a Los Angeles Basin.
In Thursday’s report, Powers refutes SoCalGas claims that permanent closure of Aliso Canyon would bluster gas reserve during rise use by critiquing dual papers expelled this year by California state regulators. Powers says those documents, a winter risk assessment expelled in Apr and a winter movement plan expelled final month, use inadequate assumptions about use and customary slackening practices and afterwards “editorialize” to emanate an sense that Aliso Canyon is needed.
Problematic State Reports
The Apr report, combined by a California Public Utilities Commission, California Energy, a California Independent System Operator, a Los Angeles Department of Water and Power, and SoCalGas, was a some-more cryptic of a dual reports, Powers tells DeSmog.
“[The agencies] were beaten behind in April, and not only by me, for great wolf by regulating archaic numbers to do their modeling,” Powers says. “In a Aug report, that SoCalGas was not a partial of, some-more accurate information is used though it’s presented with dubious denunciation to strech a conclusions they want.”
Both reports need some-more imagination to bond those dots than a layperson has, Powers adds.
Powers points out one pivotal approach a winter movement devise presents information in what he calls an “uncontrolled” manner. The plan’s unfolding assumes, though Aliso Canyon, a use of 5.2 billion cubic feet per day (bcfd) during a rise winter eventuality in 2016-2017. But a same news also states that, factoring in a new winter slackening measures and stability those from summer 2016, a limit direct would be most lower, in a operation of 4.1 to 4.2 bcfd.
“They support slackening factors like balancing supply and direct and tying a generators as a curtailment. It’s not. It’s a good government technique,” says Powers.
Powers also criticizes a winter movement devise for a arrogance that changeable era outward of a L.A. Basin to minimize healthy gas direct on forecasted rise winter days amounts to a “curtailment” of service.
As he says in the report:
This changeable of era outward a L.A. Basin is not a curtailment, that is generally accepted as a cut-off of healthy gas in response to an puncture condition. It would be a pre-planned redirection of electricity prolongation to other generating units located outward of a L.A. Basin to accommodate electric bucket in a L.A. Basin.
Aliso Canyon contains reduction than 20 percent of a ability after a four-month-long trickle that began with a Oct 23, 2015 blowout, that forced a association to recover most of a facility’s supply. The state afterwards systematic a duration on new healthy gas injections and storage during a plant while inspectors checked a wells for safety.
Without Aliso Canyon, 3 other storage comforts owned by SoCalGas — La Goleta Gas Field west of Santa Barbara, Honor Rancho circuitously Newhall, and Playa del Rey — still furnish an “overabundance” of gas, according to Powers and Food Water Watch.
Missing Blackouts and Muddy Language
State regulators and Southern California Gas warned in their Apr news — and continued to explain for months — that though Aliso Canyon, Southern Californians could face as many as 14 days of blackouts this summer, a hazard that many residents of circuitously Porter Ranch called “blackout blackmail.”
As of Sep 2, a L.A. dish has seen nothing of a threatened blackouts. Powers says a company’s shock strategy were “bogus” from the beginning.
SoCalGas maintains a position that Aliso Canyon contingency free to accommodate rise winter final for gas in the region.
A orator for a company, Melissa Bailey, told DeSmog that SoCalGas executives have not seen a news by Powers and Food Water Watch, though she forked to apart and eccentric research conducted by Los Alamos National Laboratory that “concluded that a trickery is an constituent partial of a SoCalGas system” and still required to hoop potential shortages.
“Restoring healthy gas injection during Aliso Canyon to support appetite trustworthiness for a winter heating deteriorate is vicious and though a trickery there is an increasing risk of healthy gas curtailments inspiring electric era plants, hospitals, manufacturers, refineries, and other vast users,” says Bailey.
“That’s accurately a kind of murky denunciation we highlighted in my review,” Powers says about Bailey’s statement. “It’s politicizing with language. Their conclusions are not upheld by their possess numbers.”
Powers’ examination also shows that gripping Aliso Canyon sealed could save ratepayers about $70 million a year.
“The good news is, these papers by state agencies, no matter how they spin it, indeed uncover a highway map for not regulating Aliso,” Powers says.
The Aliso Canyon storage trickery leak, that expelled an estimated 100,000 metric tons of healthy gas, caused 8,000 residents, especially in a circuitously Porter Ranch community, to be relocated for months. Some residents who have changed behind still protest of headaches, nosebleeds, and nausea. Some have motionless to leave permanently.
Residents who wish a trickery close down contend Powers’ conclusions are clearance of their position.
“There’s a larger possibility of a large trembler function here than a trance if Aliso Canyon is shut,” Save Porter Ranch President Matt Pakucko told dozens of protesters rallying circuitously a trickery on September 1.
At a same rally, Alex Nagy, comparison organizer with Food Water Watch, told protesters that SoCalGas is still regulating shock strategy in sequence to keep Aliso Canyon open since it’s a outrageous income maker. “SoCalGas stores gas here and does line trading, offered it to a top bidder, to other states and to Mexico,” she said.
Opportunities for Safety Reforms
In a revisit to a site during a trickle this past winter, U.S. Secretary of Energy Ernest Moniz said Aliso Canyon showed a need for a uninformed demeanour during gas storage reserve standards nationwide.
One intensity remodel might be sealed by California Governor Jerry Brown this month. On Aug 26, a California Senate sent SB 887, a check substantiating active reserve standards for healthy gas wells, to the governor.
SB 887, authorized overwhelmingly by both houses of a legislature, calls for continual monitoring for leaks, unchanging inspections of wells to exam their automatic integrity, and that all wells be versed with safeguards to safeguard that no singular indicate of disaster can outcome in a leak. The standards in a check are aligned with new regulations due by a Division of Oil, Gas Geothermal Resources, and could turn a inhabitant indication for reserve reforms, according to a author, Senator Fran Pavley.
The Senate sent a messenger check to Gov. Brown final week. SB 888, authored by Senator Ben Allen, establishes a state Office of Emergency Services as a lead group to coordinate responses to any destiny gas leaks.
Gov. Brown has until Sep 30 to act on all bills sent to him by a legislature in August.
