Love or hate fracking, most New Jerseyans share in lower natural gas bills

Shale gas hydraulic fracturing, colloquially called fracking, is scorned by environmental activists, but there’s no denying New Jersey natural gas customers have enjoyed the fruits of the technology.

Public Service Electric & Gas cut bills this winter by around five percent, lifting total cuts in the last two years to 35 percent. New Jersey Natural Gas, South Jersey Gas and Elizabethtown Gas Company have done likewise.

"The shale reserves in the Marcellus, in our backyard, are huge," said Kathleen Ellis, chief operating officer of New Jersey Natural Gas. "There is no arguing that the price of gas, because of increased supply, is good for our customers."

An analysis by the AARP Public Policy Institute of heating costs for seniors found natural gas customers will average $542 to heat their homes this winter, compared with $2,675 for those using fuel oil.

Those using electric heat should average around $468. That’s because while oil prices rose in recent years, electrical prices are tied to gas because of gas-fired power plants.

State officials aren’t shy about giving credit to shale gas either: when the Board of Public Utilities announced rate cuts this summer, it pointed to a new supply line—and to shale gas produced in nearby states such as Pennsylvania.

"The development of Marcellus shale has allowed New Jersey utilities to tap into natural gas reserves locally, resulting in lower delivery costs and savings for New Jersey ratepayers," said the BPU statement.

"There’s been a downward pressure on price due to greater levels of production. It’s basically a supply and demand thing," explained Amy Sweeney, a natural gas expert for the federal Energy Information Administration.

Sweeney said shale gas production flowed faster than the government reports tracking it, the most recent of which covers 2009.

"Back then it was 13 percent of supply," Sweeney said. "It very well could have doubled by now. That’s the sense that we’re getting from industry sources."

The federal government projects that by 2035, 47 percent of gas produced in the U.S. will come from shale sources.

That increased production is especially beneficial to New Jersey residents because the state has one of the highest concentrations of natural gas users in the country, according to the BPU.

The bottom line: 76 percent of New Jersey homes heat with gas, compared with 12 percent using fuel oil and kerosene and 11 percent that use electricity, according to Census Bureau data.

So you want to be a firefighter?

Freelance writer Mike Lauterborn recently got a firsthand taste of what it's like to be a firefighter at the FireOps 101 program at the Fairfield Fire Training School on One Rod Highway. The annual program, organized by the Fairfield Fire Department and several others in the area, is designed to introduce the public officials and others to the rigors of firefighter training and the challenges they face daily. Here is his account.

They say the only way to truly appreciate what someone does is to walk a mile in their shoes -- or, in this case, boots and toting close to hundred pounds of gear and equipment.

I recently had the opportunity to embed with career firefighters at the Fairfield Fire Training School on One Rod Highway to do just that. The program involved exercises providing education about firefighters' roles and an understanding of equipment and manpower needs that can give officials insight.

More than 40 firefighters, drawn from Fairfield, Westport and Stratford, were on hand to shadow a half-dozen participants, help operate equipment and lead demonstrations of both equipment and firefighting processes.

Overseen by Fairfield Assistant Fire Chief Scott Bisson, the incident commander for the day, the morning began in a classroom setting with a short film, "Smoke Showing," giving an overview about command hierarchy, firefighting strategies and safety advisories. Bisson said there are four essentials that determine the outcome of a fire: training, technology, staffing and notification.

Organizers on the drill grounds -- which includes the training center, an annex classroom, propane fire area, four-story tower, two-story burn building, vehicle "boneyard" and a new flashover simulator -- wasted no time in immersing me in the most demanding of activities: attacking a structural fire.

Suited up from head to toe in full gear and outfitted with an air tank and mask, I was placed at the head of a hose line and sent into the burn building with a support crew of "wranglers" to battle the blaze. Hay and wood pallets had been ignited in a bottom floor room, producing thick smoke that carried upwards in the unventilated structure. The result was almost zero visibility, making keeping a hand on the hose line a critical measure to safely navigate the structure.

"Typically," Assistant Chief Chris Tracy said, "an interior is fully charged with velvety black smoke, there's no clear indication of a fire and you have to listen for the pops, crackles and small explosions to find it. Guys on the line shout to each other or use signals or back slaps to communicate: one for stop, two for go. Then we look to hit the seat, or hottest point, of the fire."

At the next activity station, focused on emergency medical services, Lt. Erik Kalapir said, "Sixty to 70 percent of our calls are medical based. In Fairfield, private service AMR is the responder, however, firefighters are the first responders. With five fire stations across town, we can get to almost any home in four to six minutes, to do defibrillations, administer medicines, provide oxygen therapy and more. With the downturn in the economy and an aging population, we're being asked to do more with less. We're losing a piece of the budget pie to other community needs and constantly having to reorganize and reinvent ourselves."

The program's forcible-entry and search-and-rescue station, operated by Firefighters Salvato, Goletz and DeNitto, involved the use of "irons" -- a Halligan bar and flathead ax -- to bust through a commercial door and the "Braille" method location of a victim in a pitch black room filled with thick smoke.

A roof exercise followed, led by Stratford Lt. Sean McKenney and Firefighter Bryan Williams, who led the way up a 100-foot truck-mounted ladder to a rooftop.

"The job of the suppression crew is to open up the highest point of a structure, to help lift the smoke inside, prevent flashover, reduce property damage and save lives," McKenney said.

Ventilation was performed using a circular or vent saw. Here again, available resources were an issue.

"A properly staffed ladder company should have a minimum of four men," Williams said. "We're operating with two to three, risking injury to firefighters, forcing time constraints, preventing the saving of lives and allowing greater property damage."

The extrication station, led chiefly by Stratford Firefighter Doug Ashe, focused on the safe removal of a victim from a vehicle in a serious accident scenario.

"We assume spinal injuries, so it's safer to remove the car from around the person than to remove the person from the car," Ashe said.

Using irons to break and remove glass, a hydraulic-driven spreader to pop doors off hinges and a powerful pruner to cut through roof posts, the task is accomplished. Ashe noted that frequent changes in chassis reinforcement, live wires and airbags requires continual training.

There was one clear takeaway from the morning: these guys are passionate about their occupation and consider it their calling.

Association urges end-users to drive quality assurance

Quality assurance needs to be driven by end-users, as South Africa lacks uniform quality control, particularly of hose assemblies, in hydraulic systems, says South African Fluid Power Association (Safpa) chairperson Norman Hall.

Safpa has completed a set of standards, the Hose Assembly and Accreditation Scheme, based on the British Fluid Power Association’s (BFPA’s) standards, by which companies can be audited and endorsed by Safpa.

However, Hall notes that companies are reluctant to undertake the accreditation process unless this is demanded by the end-user.

He adds that many hose assembly suppliers mix and match hoses, collars and inserts, as well as use unbranded, unmarked and reworked hoses, which are potentially dangerous.

Components for assemblies must be compatible by design, size, type and manufacture. Further, compatibility must be proven through testing to the appropriate specifications.

“Hydraulic hose assemblies may have pressures of between 200 bar and 300 bar coursing through them, and because of the high pressures, when oil hoses burst, oil is injected into a person’s skin, which is called oil impregnation, and this is dangerous to the individual,” says Hall.

He adds people are occasionally burnt by the oil, not because the temperature of the oil is hot, but because the pressure with which it escapes the burst hose is so intense that it causes friction burns.

“Safety in hose fluid power is a significant priority, but many companies do not realise the dangers of burst hoses,” Hall explains.

Safpa aims to increase quality control in South Africa through its Hose Assembly and Accreditation Scheme, and to increase safety awareness through a one-day hose safety course.

This course, which was imported from the BFPA, has been developed to provide an introduction to hydraulic hoses, connectors and the safe assembly of these components for industrial use.

The course content includes basic hose principles, health, safety and environ- ment, hose and connector selection, hose assembly, important rules and two video presentations on hose manufacture and hose safety.

Hall urges end-users to demand quality- certified hose assemblies for the sake of employee safety and to decrease capital expenditure, as poor-quality hose assemblies need to be replaced more often.

Witness quizzed over kill motive

JYE Burns danced around in the back seat of a car as he was driven to Beerwah with the man who would allegedly shoot him dead minutes later.

The third man in the car, the driver, Shane Moroney, said he saw Shane “Capper” Oulds shoot Mr Burns after the pair left his car on Old Caloundra Rd, apparently “to do a pee”.

Yesterday Mr Moroney told Maroochydore Magistrates Court he and the two others were on their way to a drug dealer’s house at Beerwah that Mr Oulds had said they would rob for $100,000.

However, plans changed and when Mr Moroney’s passengers left the car he said he saw Mr Oulds shoot Mr Burns.

Mr Moroney said Mr Oulds claimed to have shot Mr Burns after he threatened his family.

Mr Burns also allegedly claimed to be planning a “home invasion” on Mr Moroney.

Mr Moroney said Mr Oulds got back in the car and told him: “I wouldn’t let anything happen to you.”

Under heavy police guard, Mr Moroney took to the stand for a second day of giving evidence at the murder committal of Mr Oulds.

Mr Moroney is the key witness in the case as the only person to see the alleged murder on July 8 last year.

He was quizzed about why he was “unable to provide (police) with any motive” for why Mr Oulds killed Mr Burns when he was first interviewed three days after the man’s death.

Mr Moroney did not tell police the explanation he received from Mr Oulds until he gave a second statement on July 21.

He said he did not ask Mr Oulds more details about why he had shot Mr Burns because he was frightened.

Mr Moroney said he did not stop Mr Oulds from throwing his mobile phone into Maroochy River with the alleged murder weapon because he was “scared” of his friend and also of having any evidence that could implicate him in a murder.

The pair drove to a car wash where Mr Oulds used a hydraulic hose to wash dirt and dust off the vehicle before they continued to a nightclub at Mooloolaba where Mr Oulds allegedly said they had to be seen on CCTV cameras.

Mr Moroney eventually left the club by himself, but not until after Mr Oulds disposed of a coat in a rubbish bin outside.

He said he had driven only about a kilometre when he was pulled over by a police car, which he feared had stopped him in relation to the alleged murder.

His heart pounded as police walked to his car and he quickly weighed up if he would tell the officers he had just seen an alleged execution-style murder hours earlier.

Police had stopped him for a random breath test, which had a negative result.

Mr Moroney said he also lied to police the following morning when he signed a statement saying his mobile phone had been stolen, a story he fabricated to claim insurance for the missing phone.

He was later arrested for the murder but was given indemnity after he gave police a statement saying Mr Oulds had shot Mr Burns.

The committal continues today. Mr Moroney is expected to continue with his evidence.
