Frac smack: Industry faces DNR violations, warnings

Almost one-fifth of Wisconsin’s 70 active frac sand mines and processing plants were cited for environmental violations last year, as the industry continued to expand at a rapid clip.

Violations included air pollution, starting construction without permits, and an accident at the Preferred Sands mine in Trempealeau County where a mudslide during a heavy rainstorm damaged a neighboring property.

In addition, the state Department of Natural Resources cranked out letters of noncompliance, warnings to fix a problem before it becomes serious enough to merit a notice of violation, at numerous plants.

“Some of these companies should have known better,” said Marty Sellers, a DNR air management engineer. “They seem to put construction and production ahead of regulations.”

Usually, Sellers said, the DNR expects 90 percent of companies in a regulated industry to comply with rules on their own. But in his visits to a dozen frac sand facilities, Sellers encountered the opposite pattern, and he sent letters of noncompliance to 80 percent to 90 percent of the sites.

DNR compliance officials acknowledged they have been stretched thin monitoring the sand industry, which has grown from a handful of sites five years ago to more than 100 permitted mining, processing or transport plants today.

Wisconsin is the nation’s leading supplier of frac sand. The companies mine, sort and wash sand for use in hydraulic fracturing of shale to extract natural gas in other states.

Gov. Scott Walker has proposed two new DNR positions in his budget to monitor the sand industry, by shifting $223,000 from other parts of the budget.

The Wisconsin Industrial Sand Association, an industry trade group representing five large companies, applauded the move. Increasing staff will help to ensure that all mining companies operate according to state laws, the group said in a news release.

Citizens aided enforcement

Dust generated the most community complaints about frac sand operations in 2012, but most violations involved stormwater permits.

DNR environmental enforcement specialist Deb Dix said some of the violations resulted from residents’ complaints. Perhaps because sand mines have provoked so much controversy, citizens have been alert to problems, Dix said — more alert than for similar problems that can be caused by road work or other construction.

In response to complaints in the Frac Sand Sentinel, an e-newsletter for anti-mining activists, that the DNR was slow in responding to a runoff concern, a DNR stormwater specialist wrote in, explaining that the extra vigilance was helpful.

“I do greatly appreciate any and all photos and reports,” according to a statement attributed to Ruth King. “It is precisely because I am only a half-time employee and cannot be everywhere at all times that we really, really need concerned citizens to be our eyes and ears.”

In neighboring Minnesota, where Democrats are in control of the Legislature and governor’s office, a Senate committee approved a bill Tuesday calling for a statewide moratorium on new mine development and a study of the industry’s environmental effects.

But in Wisconsin, where Republicans are in control, the DNR decided last year that existing non-metallic mining regulations were sufficient to handle the frac sand boom, and politicians appear unlikely to move toward more regulation.

The proposed two new DNR positions most likely would be focused on mines’ compliance with air quality regulations, said Tom Woletz, the DNR’s point person for frac sand.

“Many Wisconsinites have the impression of the DNR as a big strong agency, but it’s not what it was 10 years ago,” said Pilar Gerasimo, a journalist and environmental activist in Dunn County. “They are understaffed and have not been able to keep up.”

Gerasimo said that she worries that under the Walker administration, the DNR is doing more to “work with” businesses that are potential polluters and spending less time tracking potential problems.

Air regulator Sellers said he only inspects large operations that dry sand, a process that poses the greatest risk of dust pollution, on a rotating basis and when mines are testing emissions for permitting purposes. The air quality compliance staff doesn’t inspect small mines regularly unless someone complains about them.

A conveyor pours crushed frac sand into a stockpile before it is washed and sorted by grain class size June 20 at Preferred Sands mine in Blair.

Two significant runoff incidents

The DNR referred two May 2012 frac sand mine violations that caused significant environmental damage to the Wisconsin Department of Justice. The agency said it is reviewing the cases.

At the Preferred Sands mine in Trempealeau County, the mudslide that flooded a neighbor’s property during a heavy storm violated its stormwater permit. The Minnesota-based mining company also had multiple violations of its air quality permit.

Todd Murchison, the Preferred Sands regional manager, has said that the company had learned a lot from the accident, changed its policies and was cooperating with the DNR.

At the Burnett County mine owned by Minnesota-based Interstate Energy Partners, a leak in a holding pond let silt-laden water leak into the St. Croix River for a few days before it was noticed by a hiker.

“A release like that could have been devastating to wetlands or the St. Croix if left uncorrected,” Dix said about the leak. “The regulations are there to protect the environment, from catastrophic events and ongoing damage.”

Three more companies were fined in 2012.

Last March, the DNR received a complaint about muddy water in a stream and found a leaking holding pond at the Panther Creek Sand mine in Clark County. According to Dix, the damage was minor and the company fixed it right away; it was fined $464.

Bear Creek Cranberry in Monroe County paid $868 for serious problems with its environmental protection plan.

The Chippewa Sand Company notified county officials in April that a pond holding wastewater overflowed into a drainage area, eventually soaking into the soil. Dan Masterpole, the Chippewa County conservationist, said the company was fined $2,795 and made changes to prevent similar problems in the future.

Runoff problems are more likely in the spring as snow melts and mines resume operations, Masterpole said, so Chippewa County has scheduled inspections for this spring.

Nine companies that received violations faced no fines, Dix said. Their violations largely were either paperwork problems or other easily corrected issues.

Few air pollution violations so far

Dust pollution, a potential health concern as well as a nuisance, attracted the most attention from citizens, but few sand mines received serious air quality violations.

Companies monitor dust levels to protect workers. They spray water on exposed soil and use specialized equipment such as dust collectors and covered conveyors to prevent pollution, Woletz said.

Trouble occurs if that equipment fails.

That’s what happened at the Pattison Sand transport plant in Prairie du Chien. Sellers received lots of calls about dust coming from the portable system used to load sand from trucks to train cars.

Between his busy schedule and the fact that the portable plant comes and goes, it almost was a year before Sellers observed the operation in action. The callers were correct: He saw dust escaping from the area where the truck unloaded sand.

He also noted a problem that day with the conveyor loading to the railcar. Sellers watched the operator try to fix the seal without success, and then continue to transfer the sand.

He wrote Pattison Sand, an Iowa-based company, a letter of noncompliance, warning it to fix the problem and improve its dust prevention protocols or face fines.

‘Growing pains’ of new industry?

Dix said some of the recent violations were a result of the frac sand boom and new people moving into the industry who were not familiar with the rules and regulations.

However, Sellers said he also has seen problems from experienced companies.

He wrote Connecticut-based Unimin a letter of noncompliance for starting construction at its Tunnel City mine without proper permits. And neighbors of the U.S. Silica mine in Sparta alerted him of dust problems during construction work by the Maryland-based company.

Resident Gerasimo said the laws aren’t tough enough on mining companies who take a lax approach to environmental protection.

“For frac-sand mining interests, the risks of being held accountable are low and temporary. The fines are meaningless in relation to both the potential profits and damages in question,” Gerasimo said. “Two new agents isn’t going to change that.”

DNR’s Dix, however, said the agency expects to see fewer violations in the future.

“Sometimes, it’s just the growing pains of an industry,” Dix said. “Usually, once we catch them, they get it corrected, and we’re done.”

  1. Seems quite a few more blue dots than red. Could we overlay agricultural spills with satisfactory agricultural operations if you are going top make this comparison? I would prefer silica turbitidy (which settles) to fecal contamination (which does not…)

  2. Great point. It seems that our environmentist, au-naturale, anti-industry regulators all too often lose perspective of where the most common contamination problems affecting the public health truly lie.
