Lightning strike, explosion cause release of saltwater

WILLISTON, N.D. – A lightning strike early Sunday caused an explosion, fire and release from a saltwater disposal site about 12 miles northwest of Williston, the North Dakota Department of Health said Tuesday.

The incident destroyed the site, which is owned by Oasis Petroleum, the department said.

About 1,200 barrels, or 50,400 gallons, of saltwater, a byproduct of oil production, and one or more barrels of residual crude oil were released as a result of the incident, the Health Department said.

About 995 barrels, or 41,790 gallons, have been recovered.

Health Department inspectors and the North Dakota Industrial Commission, Oil and Gas Division, are on scene and working with Oasis on sampling and remediation. Initial screening indicated that no saltwater reached a nearby intermittent stream, the Health Department said.

Faces of the Boom: In McKenzie County, emergencies require double duty

WATFORD CITY, N.D. – In her first three weeks on the job, the new McKenzie County emergency manager visited the National Weather Service, held a Skywarn training course and met with the Red Cross.

Karolin Rockvoy didn’t expect to apply what she learned so quickly, until an EF2 tornado struck an RV park south of Watford City last week.

“Then we put it all to work,” Rockvoy said.

McKenzie County recently expanded its emergency management and veteran services offices to two people. Jerry Samuelson, who has held those duties for 17 years, said the need to add more staff was primarily driven by oil-related incidents.

“When all the oil activity came in, we were running around with all the spills. We’ve had oil well blowouts,” Samuelson said. “That became a job all in itself.”

In addition, the emergency managers assist the sheriff and police departments, five rural fire departments and two ambulance services in the county, all of which have seen dramatic increases in calls for service.

While most North Dakota counties of comparable size have a half-time emergency manager, McKenzie County – where the state’s oil activity is most heavily concentrated – needs two people to handle it all, Samuelson said.

In addition, demand for veteran services has increased with the influx of new residents.

McKenzie County used to have about 550 veterans before the oil activity began, Samuelson said. He now knows of two oil industry businesses in Watford City that employ about 90 veterans on their own.

On Memorial Day, Samuelson and Rockvoy had their veteran services hats on in anticipation of a community service. Rockvoy didn’t like the look of the clouds, so she started calling the National Weather Service and they began the ceremony 20 minutes early.

They then had to switch gears and go into emergency management mode, when a tornado touched down and emergency responders raced to the scene.

Days after the storm, the two were already talking about changes the county needs to consider to require housing camps to have shelters and emergency plans.

“We have the next 30 to 90 days to educate people,” Rockvoy said. “We have a lot of RVs around here. I think we can use this as an educational thing.”

Samuelson said he used to be primarily concerned with the need for winter storm shelters for the out-of-state workers and families who live in RVs and temporary housing year-round. The tornado highlights the need for summer storm shelters as well, he said.

“There are places they can go, but it’s few and far between,” Samuelson said.

Expanding siren systems is another need for the county, Samuelson said. Watford City has one siren, which he said has always been hard to hear, but now the city limits have expanded. Communities such as Arnegard and Alexander also have housing camps beyond their city limits that wouldn’t be able to hear the sirens, he said.

While their attention was focused last week on extreme weather, protecting the county’s water and environment from oil-related spills will continue to be a major priority. Rockvoy said she’s especially concerned about spills that companies don’t report.

“When they don’t report spills, you wonder how much they really clean them up, too,” Rockvoy said.

Health department responds to several spills

BISMARCK, N.D. – A vehicle accident, a cow rubbing against a valve and leaking pipe connections contributed to several unrelated oil and gas spills this week in western North Dakota, the Department of Health said Thursday.

On Monday, about 2 gallons of crude oil and 100 gallons of diesel fuel were released as a result of a vehicle accident. The driver of a tractor-trailer owned by Triple C Services pulled over to the side of the road during heavy rain and hit a soft shoulder. The trailer and the tractor slid off the road, spilling liquids into a slough. A response team was called to work on the site.

On Tuesday, about 20 barrels, or 840 gallons, of natural gas condensate were released near Sully Creek, a tributary of the Little Missouri River. A cow is suspected of having rubbed against a valve on a storage tank at a site owned by OneOK Rockies Midstream and the valve was accidentally opened. Cleanup of the area has begun and containment booms have been put in place as a precaution.

Two other spills that occurred Tuesday involved produced water, also known as brine, a byproduct of oil production.

In one incident, a valve or piping connection leaked about 200 barrels, or 8,400 gallons, of brine from a Crescent Point Energy well two miles west of Wildrose in Williams County. The spill affected cultivated land. About 80 barrels, or 3,360 gallons, have been recovered.

The second brine spill occurred at a well site owned by Samson Resources Co. six miles southwest of Crosby in Divide County. A leak in a valve or piping connection caused brine to spray. About 410 barrels, or 17,220 gallons, were contained on the site and 15 barrels, or 630 gallons, escaped onto cultivated land.

In both of the brine spills, the impacted soil will be removed to a licensed disposal facility.

Health department inspectors are monitoring the cleanup efforts.

Tour gives higher ed officials a glimpse of oil industry careers

Amy Dalrymple/Forum News Service

TIOGA, N.D. – North Dakota’s higher education leaders got a peek into the oil and gas industry Wednesday to better understand how to prepare workers.

Oilfield geologist Kathy Neset of Tioga, who also serves on the state Board of Higher Education, invited board members, university system staff and campus presidents to tour several oilfield locations. Hess Corp. led the group on a tour of a drilling rig, the Tioga Gas Plant and the Tioga Rail Terminal.

“As North Dakota educators, they can see firsthand what industry needs and how we can link the two together,” Neset said.

Steve McNally, general manager for the company’s North Dakota operations, said Hess has 80 job openings in the Bakken right now.

“You name it, we need it,” McNally said.

In particular, the industry is looking for workers who can collaborate with others and work together to solve problems, McNally said.

“We need all the engineers you can handle,” Ken Goebel, a chemical engineer who manages the gas plant, told the educators.

North Dakota University System leaders want to better understand the oil and gas industry so they can be more responsive, said Chancellor Larry Skogen.

“Higher education is absolutely vital to the development of this industry,” Skogen said.

Board member Grant Shaft of Grand Forks said the tour was an eye-opener for him.

“We just don’t know a lot about this,” Shaft said. “I wish there was a way to get more of the population, particularly kids, to see the types of things we saw today.”

Adam Sagaser, a North Dakota State University geology student who is in his third summer interning in the Bakken, said having industry experts speak in class can help students understand who types of job opportunities are out there.

D.C. Coston, president of Dickinson State University, said a recent survey showed that of the university’s graduates who stay in North Dakota, 23 percent work in the energy industry. It’s important for education to continue to work with industry to evolve its programs, Coston said.

The board, which typically meets at college campuses, will hold its meeting today at Neset Consulting Service in Tioga. They were spending Wednesday night at a Tioga crew camp.

Tornado raises concerns over camper preparedness

By Katherine Lymn and Amy Dalrymple

WATFORD CITY, N.D. — Stella Schlosser and her family of five didn’t have a plan for seeking shelter from a tornado in their RV near Watford City.

On Monday night, they didn’t have time to plan when her husband Kevin’s cellphone flashed a tornado warning as they were eating dinner.

“When we looked out that window, all you could see was (a) funnel,” said Schlosser, a mother of three. “It was here.”

Kevin directed the family to a structure next door to their camper that has a concrete foundation, and the family, barefoot, ran out and hunkered down beneath it. Schlosser was grateful Tuesday for her husband’s quick thinking.

“Looking around here, I wouldn’t know where to go,” Schlosser said. “I wouldn’t have a clue.”


Being prepared

The danger of being in an RV during a storm was on the minds of many Tuesday in the Oil Patch, where thousands live in campers, trailers and other types of temporary lodging as housing development lags behind population growth. Often, the camps are out in the country, out of range of emergency sirens or solid shelter.

Williams County Emergency Manager Mike Hallesy said the county, which includes the boomtown of Williston, has been reviewing the placement of emergency sirens within the city since it has grown.

But Hallesy said some responsibility also rests on the RV camps.

“It’s somewhat maybe inherent for the camp operators to look into safety notification equipment,” he said, adding the camps can invest in equipment and hook it into the county’s system so any countywide siren also is blared at the camp.

Dunn County’s seat, Manning, doesn’t have a siren because it’s an unincorporated city, said county Emergency Manager Denise Brew. She said she plans to approach the county commission about adding one.

When it comes to emergencies, for Brew, it’s all about having a plan.

She said it’s up to the park operator or the oil company that has housed them at a camp to have a plan in place for notification and evacuation of residents.

“They should be able to tell you, ‘OK if you’re near the city of Killdeer, here’s where you should go and work that out and just go from there,’” she said.

John Paul Martin, warning coordination meteorologist with the National Weather Service in Bismarck, advises people to be aware of the potential for bad weather. When a watch is issued, it’s time to seek a permanent shelter, he said.

“The best answer is that everyone have a storm shelter,” Martin said. “But that’s not feasible.”

Liz Leitheiser of Montana lives in an extended-stay motel under construction adjacent to where the tornado struck Monday. She, her grandson and neighbors took shelter in the building’s crawl space Monday night. On Tuesday, she was telling her neighbors who live in RVs about the crawl space for future storms.

“Last night taught me something,” Leitheiser said.


Little warning

Martin said even waiting until the warning is issued can prove to be too late.

But in the case of Monday’s tornado, residents didn’t have warning.

Severe thunderstorm warnings had been issued since about 4 p.m. for a storm that started in the Sidney, Mont., area, Martin said.

The first indication officials received of a tornado was a call from the Watford City Police chief about a funnel cloud south of town. A spotter also reported a funnel cloud and a tornado warning was issued at 7:46 p.m., Martin said.

“The tornado was actually on top of them,” said Martin, as he and a team assessed the damage Tuesday. “For the folks here, there was basically no warning.”

The weather service advises people who live in mobile homes or campers to seek permanent shelter with friends and neighbors.

“The issue here is friends and neighbors are also in semi-permanent housing,” Martin said. “Where are they all going to go? I don’t think there’s an answer to that.”

Martin said another option is to seek shelter in a low-lying area. He heard from people who sought shelter in a ravine behind the affected park and were not hurt.

Juniper Campground at Theodore Roosevelt National Park’s North Unit was evacuated after earlier reports showed the tornado’s path might go through it. A ranger collected the eight groups of campers and brought them to the west edge of the park to Oxbow Overlook until it was safe to return, chief ranger Dean Wyckoff said. The groups ended up seeing heavy rain, high winds and hail.

At the park, rangers and campground hosts monitor weather in case an evacuation is needed. The restroom buildings can serve as shelters, Wyckoff said.

But with the NWS information received Monday night, “it was more prudent to get them away from that particular area,” he said.

The campground is about 10 miles southwest of where the tornado touched down.

“Especially if you’re out doing the camping thing … keep some kind of communication open so you know what possibly could be coming,” Brew said. “If not, look at the sky.”


‘A wakeup call’

Compounding the notification problem, smaller RV parks that settle in rural areas often aren’t registered with their county, causing headaches for emergency responders who try to find them.

“There are still many that are just popping up in the middle of nowhere that we do not know where they are, and so it makes it difficult for public safety to try to notify locations that don’t exist,” Hallesy said. “It brings up the whole ball of wax as to where are you, how do we get to you, what’s the nature of this call.”

Hallesy estimated as many as 6,000 people live in campers in Williams County.

That’s not including workforce housing, or “man camps,” which he said are a bit safer.

“I rate the risk assessment on mobile RVs much higher than I do a man camp because the man camps are anchored, they’re steel-structured units that are all bolted together, they’re big complexes,” he said, “where a camper on wheels, (they’re) typically are not securely anchored nor is the equipment meant to withstand any sort of severe weather.”

Dakotaland Lodging, which has manufactured housing for about 600 people, has its own emergency notification system for its camp outside Tioga, company President Alan Spencer said.

Other Dakotaland camps — in Alexander, Williston and Dickinson — are close enough to city sirens to be covered, but the rural Tioga camp’s necessitates a text or voice call alert that residents are automatically signed up for when they move in.

“Certainly they’re out by themselves,” Spencer said.

About 200 residents live in the Tioga camp, off U.S. Highway 2.

“Locations that don’t have sirens are at a huge disadvantage, and they’re in harm’s way,” Spencer said. “That’s why we’ve added the call systems.”

Dakotaland has arrangements for shelter in the case of severe weather — residents could go to the Catholic church, senior citizens center in Ray or to the high school and elementary schools in Tioga.

Sand Creek Estates, which has parks in Tioga and Williston, has similar arrangements — the Williston High School auditorium is available for the 238 residents at that park, for example, said Janie Kastrinos, a property manager with the company. Local television stations broadcast shelter sites alongside severe weather information, she said.

Management teams for the Dakotaland locations had a call Tuesday morning in light of Monday’s storm to review their emergency plans, Spencer said.

“This is a wakeup call for everybody to make sure we have a plan in place.”

Watford City tornado: ‘There are people that have lost everything’

Amy Dalrymple/Forum News Service

WATFORD CITY, N.D. – Aly and Derrick Dickinson’s baby boy is due in six days, but Monday night’s tornado demolished their RV and the nursery they had set up for him.

“In a split second, it was all gone,” said Derrick Dickinson, an oilfield worker from Missouri.

People who moved from across the country to northwest North Dakota for work were picking up the pieces Tuesday after a tornado leveled at least a dozen RVs that housed workers and families.

“There are people that have lost everything and they need help,” said Brenda Hendrickson, a Red Cross volunteer from Bismarck.

Nine people were treated for injuries and one was critically injured, said McKenzie County Emergency Manager Karolin Rockvoy. The one with more serious injuries is a 15-year-old girl who was airlifted to Trinity Health in Minot, Rockvoy said.

The tornado that hit the housing camp before 8 p.m. Monday about 5 miles south of Watford City had estimated wind speeds of 120 mph, the National Weather Service said Tuesday.

John Paul Martin, warning coordination meteorologist for the weather service in Bismarck, said the tornado was an EF2 on the enhanced Fujita scale that rates the strength of tornadoes from 0 to 5.

Martin said most tornadoes in North Dakota are weaker, an EF0 or EF1.

An EF2 tornado has winds in the 110 to 135 mph range.

The tornado tossed the frame of a trailer 120 feet in one direction and a car that was parked next to it was on its roof about 60 feet in the opposite direction, Martin said.

Fifteen homes were either destroyed or severely damaged.

“It looks awful. The folks who were here lost everything. A lot of out-of-state people working,” said Jeff Savadel, meteorologist in charge, one of the National Weather Service team members assessing the site Tuesday.  It’s pretty tough to see.”

Aly Dickinson, from Louisiana, said the couple would not have survived the storm if they hadn’t decided to go out to eat Monday night. When they returned, their RV was gone completely and their cats were missing. Aly said she buried one cat Tuesday and they were still looking for two others.

Connie Chadwick and her boyfriend, Brian Wieman, were feeling lucky Tuesday for escaping injuries after they rode out the tornado in their camper.

The storm blew out the RV’s windows, and debris was flying around inside as the truck drivers took shelter.

“It was horrifying,” said Chadwick, of California. “You’re in a camper. There’s nowhere to hide.”

Resident Anthony Beyda took shelter from the tornado in the hallway of his RV. The walls caved in as debris struck the side of the structure.

“RVs ain’t made for it. It wasn’t even a contest,” Beyda said.

Beyda got 16 stitches in the side of his head and spent the night in a Red Cross shelter set up at the Watford City Civic Center.

“God loves me,” said Beyda, a welder from Wyoming, who was reunited with his cat at the shelter.

Marvin Dockstader, who lives in an RV up the hill from the area most severely damaged, spent Tuesday cleaning up debris and looking for his tools after the tornado. He was at the movies when the storm hit his trailer and moved it 6 feet. The storm tossed another trailer he was helping renovate down the hill.

“There’s pieces everywhere,” said Dockstader, a construction worker from Arizona.“Everybody’s kind of walking around in shock.”

Marvin Townsend, a truck driver from Florida, fled from the storm in his pickup with his wife and watched the tornado from a half-mile away.

“I’m glad it didn’t hit at night,” Townsend said. “There would have been a lot more people hurt.”

Brenna Schlosser, 12, helped her neighbors clean up Tuesday, making a pile of dirty sweaters and clothing she found in the debris.

“I can’t help but think that could have been us,” said Schlosser, whose family is from Wisconsin.

Eyewitnesses have reported three separate tornadoes, but Martin said that may be almost impossible to confirm. Witnesses also had conflicting reports about how long the tornado was on the ground.

“It appears to have been fairly short-lived,” Martin said.

The damage was focused in the area of the housing camp, with multiple RV parks and man camps nearby that had little to no damage.

The tornado went “right by” Targa Resources’ gas plant south of Watford City, said plant administrator Beth Mayden. The plant wasn’t affected, she said, other than the portable toilets being overturned.

Debris littered nearby ditches and fields, and crews worked Tuesday to repair downed power lines.

“We are very fortunate that we didn’t have any fatalities last night,” McKenzie County Sheriff John Fulwider said. “It’s a really isolated spot that the tornado did touch down. We were very lucky.”

The Red Cross housed eight people Monday night at a shelter and planned to keep it open Tuesday night.

A thrift store that is in the basement of Glory of the Lord Family Ministries provided shoes, kids’ clothes and other items to storm victims Tuesday, said the Rev. Barbara Becker. One out-of-state couple told Becker they planned to return home.
“They have nothing. What little they had, they lost,” Becker said. “At least they have friends and family at home.”

How to help:

People who want to assist victims of the Watford City tornado are encouraged to donate to the American Red Cross, which is providing shelter, food and other assistance.

Blankets, toiletry items, clothing, shoes and other donations can be dropped off at the Glory of the Lord Family Ministries, 118 4th Ave. SE, Watford City.

Construction to start on worker training facility

WILLISTON, N.D. – Work will begin this week on a new TrainND workforce training facility here after the oil industry provided nearly $1 million in donations.

TrainND’s Northwest Center at Williston State College proposed a building project to more than double its size and offer more programs. The $7.5 million project had funding from a variety of sources, but needed about $1 million more, said CEO Deanette Piesik.

Last week, Oasis Petroleum presented TrainND with a donation of $165,000 during the Williston Basin Petroleum Conference. That contribution, along with $150,000 from Statoil and $150,000 from Steel Energy Services, allowed the project to move forward this construction season, Piesik said.

Several other energy companies have also made smaller donations or committed dollars to the project.

“We feel we’re very close to the $1 million,” Piesik said.

In 2013, TrainND in Williston provided training to 386 businesses and 11,200 participants, including some who took more than one training course.

Oasis CEO Tommy Nusz said the company wanted to partner with TrainND, where Oasis employees receive training on drilling rig operations, commercial driver’s license training and technical training such as well control.

“What we want to do is make sure that when people go to work every day, they come back in the same condition that they left,” Nusz said.

The new 19,740-square-foot training and educational center will allow TrainND to offer more technical oilfield programs. TrainND also plans to diversify to offer workforce training in construction, health care and other industries that are expanding in northwest North Dakota.

A ceremonial groundbreaking was held recently and construction gets under way this week, Piesik said.

TrainND is still seeking another $500,000 in donations for a parking lot and other features, she said.

Funding sources include $1.75 million from the Department of Trust Lands, $2.5 million from the Bank of North Dakota and $500,000 in matching funds from the North Dakota Board of Higher Education and $750,000 from the city of Williston’s STAR Fund.

Faces of the Boom: Young engineer expects long career in oil business

Kevin Black, pictured Thursday, May 22, 2014, at the Williston Basin Petroleum Conference in Bismarck, is a recent North Dakota State University engineering graduate who works for Baker Hughes in Minot, N.D. Amy Dalrymple/Forum News Service

BISMARCK – When North Dakota State University graduate Kevin Black was looking to start his career in 2011, he feared he’d have to leave his home state.

“I really had every intention of going to Minneapolis because up until that point, if you were an engineering grad, the odds were you were going to have to go to Minneapolis or someplace out of state if you wanted a job in the engineering field,” said Black, who grew up in Grand Forks.

Instead, Black decided to explore opportunities in western North Dakota, where the Bakken oil boom was creating a demand for educated workers.

Black, who spent his last year at NDSU as student body president, started out in the Bakken “in the mud and getting dirty,” collecting samples at oil well sites for testing and analysis.

After nine months in the oil industry, Black began working for Baker Hughes, one of the world’s largest oilfield service companies.

He advanced from working in the field to spending more of his time in the company’s Minot office doing sales and business development. Black, 26, is an account coordinator for the company’s line of production fluids that prevent corrosion and mineral deposits from developing in oil wells.

“If people are willing to come out here and start from the ground up and work hard, the sky’s the limit,” said Black, whose degree is in industrial engineering and management. “I’ve been blessed to be a benefactor of the times, I guess.”

Black is the third generation of his family to work in the oil industry in North Dakota. Oil brought Black’s grandfather, a mud engineer, to Williston in the 1950s during the state’s first oil boom. Black’s father and uncles operated a drilling fluid business in North Dakota in the 1980s.

Unlike the previous generations that experienced busts, Black is expecting to work in the oil industry for the long term.

“I think they all recognize this is very different than the past oil booms,” said Black, who also has several cousins working in the industry in North Dakota.

Black’s wife, Kalli, is also a North Dakota native, and now helps her father run Artz Insurance in Westhope.

During the past few years, Black has recruited some of his friends to work in the oil and gas industry, and he’s seeing a reversal of the trend of college graduates leaving North Dakota.

“More and more I meet people from the state who are moving back either home or moving from the east to the west because they recognize the tremendous opportunity that’s out here to start a career and grow pretty quickly,” Black said. “It’s exciting to see.”

Attorney turns to Industrial Commission in flaring dispute

BISMARCK – An attorney involved in the recently dismissed class-action flaring lawsuits is now asking the North Dakota Industrial Commission to determine if mineral owners are owed royalty payments.

Attorney Derrick Braaten delivered the requests Friday to the North Dakota Industrial Commission after a federal judge ruled that the mineral owners failed to exhaust their administrative remedies through the Industrial Commission.

Mineral owners filed lawsuits against 14 oil and gas companies that operate in western North Dakota, claiming they were owed millions of dollars in royalties for natural gas they allege was illegally flared from oil wells. All but one case were moved to federal court.

U.S. District Court Judge Daniel Hovland ruled last week that the court lacks jurisdiction because the administrative remedies were not exhausted.

Braaten, who represents the mineral owners, said last week that Hovland’s dismissal was not on the merits of the cases.

Hovland’s ruling noted that the Industrial Commission has broad authority to regulate oil and gas activities in the state, including determining whether gas is being flared in violation of state law and ordering the payment of royalties and taxes on improperly flared gas.

In Braaten’s letters submitted to the Industrial Commission, he asks for the commissioners to use their discretion to take up the matter and determine whether the 13 companies flared gas in violation of North Dakota law.

The Industrial Commission, which consists of Gov. Jack Dalrymple, Attorney General Wayne Stenehjem and Agriculture Commissioner Doug Goehring, meets Tuesday.

CEO calls for oil exports to strengthen U.S. economy

BISMARCK – The CEO of Marathon Oil Corp. called for lifting the U.S. ban on crude oil exports Wednesday during his keynote address at the Williston Basin Petroleum Conference.

“Lifting today’s crude oil exports restrictions would help strengthen the U.S. economy, foster job creation and promote the efficient development of the domestic energy sector,” said Lee Tillman.

The current ban threatens U.S. oil production because refineries have a limited capacity to process light, sweet crude such as the oil being produced from the Bakken, said Tillman, who leads one of the major companies operating in North Dakota.

Studies have shown that it would lower the price at the pump for American consumers, Tillman said.

“More production in the Bakken means more exports, less imports, greater energy security and greater economic security,” he said.

Reducing a backlog of federal drilling permit applications is critical for the industry, Tillman said. He complimented North Dakota’s federal delegation and said the right public policy paves the way for investment and new technology.

“As Congress considers the role of federal policies and regulations, we hope they will take cues from North Dakota,” Tillman said. “This state has a history of successful state-led regulations of oil and natural gas production.”

Marathon is working to reduce the amount of water used for oil and gas production. In the Eagle Ford formation in Texas, the company has reduced water use per well by 45 percent during hydraulic fracturing, he said.

In the Bakken, the water that is a byproduct of oil production has such high salinity that it makes recycling more challenging. But this year, Marathon will do field pilot testing of methods to conserve water. One test involves treating the wastewater so it can be used as a drilling fluid rather than injected into a disposal well.

“It’s a challenge, but we’re not giving up on it,” Tillman said.

Tillman outlined some of the benefits oil and gas development have brought to North Dakota, including 75,000 new jobs and more than $2.9 billion in oil and gas taxes recently paid to the state.

Also Wednesday, State Treasurer Kelly Schmidt announced that deposits into North Dakota’s Legacy Fund will exceed $2 billion this month.

At this pace, the fund is on schedule to receive $3 billion by the end of the 2013-15 biennium. Thirty percent of revenue from North Dakota’s oil and gas taxes are deposited into the Legacy Fund, which was created in 2010 by a vote of the people. State lawmakers can’t spend money from the Legacy Fund until July 1, 2017.

Tillman called for oil and gas companies to be mindful of the communities where they operate.

“We must be responsible corporate neighbors and never lose site of the fact that we are a guest in these communities,” he said.

The conference, which concludes Thursday, has attracted a record of more than 4,100 attendees.

Revenue from the conference will support geological exhibits at the North Dakota Heritage Center, support nonprofit organizations in western North Dakota and support scholarships for North Dakota students, Tillman said.

“We should all be very proud of the ways our industry is giving back,” Tillman said.
