KDNK Exclusive: Enterprise compressor station violates Clean Air Act

Recently state regulators announced that benzene contamination on Parachute Creek has slowed to a trickle at the site of the Williams processing plant that leaked natural gas into the groundwater earlier this year. But as KDNK’s Ed Williams reports, another gas facility just miles away is under investigation for multiple alleged violations of the Clean Air Act–including rules regulating benzene emissions.

Records reveal a history of pollution and compliance problems at oil and gas site

The Enterprise Products Jackrabbit Compressor Station, which pulls natural gas from area wells to send into pipelines running through Garfield County, has been in violation of state and federal laws on air pollution for at least three consecutive years, according to the Environmental Protection Agency.

Located on top of a remote hill just west of Parachute Creek, federal regulators have had their eye on the facility since 2011, when the EPA flagged it and five other facilities on an agency watch list of potential serious polluters in Colorado. The Enterprise compressor station is the only facility still on the EPA list from 2011 because of alleged continued Clean Air Act breaches.

The majority of past violations at the compressor station come from the facility exceeding its limits on emissions of so-called hazardous air pollutants such as carbon monoxide, hexane and volatile organic compounds, as well as permit violations stemming from Enterprise’s alleged failure to install pollution-limiting equipment.

The Colorado Department of Pubic Health and Environment (CDPHE), which enforces the federal Clean Air Act on the ground, fined Enterprise more than $250,000 for those violations in 2011, along with an additional $16,000 fine for benefiting financially by not complying with environmental rules.

“Instead of investing in compliance, they were able to invest that money elsewhere,” potentially profiting from the funds that should have gone to pollution controls, said Shannon McMillan, who oversees field inspections for the CDPHE’s air pollution division.

She added that the previous Clean Air Act breaches at the Jackrabbit Compressor Station have had an impact on the environment, though it’s unclear exactly what those impacts are …

… Inspectors have alleged the facility is currently in violation of the same rules it has been fined for in the past. They also have found multiple violations of state and federal rules aimed at preventing and reporting benzene emissions.

According to the EPA’s facility report on its website, inspectors allege that Enterprise is in violation of 10 different Clean Air Act rules at the Jackrabbit Compressor Station …

… Breaches of pollution laws are not uncommon in rural Garfield County, where a vast array of industrial infrastructure supports over 10,000 active oil and gas wells. EPA documents show Garfield County is home to 16 percent (eight out 49 facilities) of the state’s “high priority violators,” a term used to denote facilities under scrutiny from regulators for alleged Clean Air Act violations.

Like the Enterprise compressor station, several priority violators are located in the heavily industrialized area north of Parachute, near the site of a natural gas leak that sprung from a Williams Midstream-owned pipeline valve and contaminated the groundwater and the nearby creek with benzene earlier this year.

    The recent downpour on Parachute Creek that tore up roads, culverts, and as it appears gathering lines (in-service unknown) at the base of Mt. Calahan, and flowed over the bridge at Howard Orona’s place. If this downpour hit on the Williams spill site, it had to wash hydrocarbons out/off the soils and down the creek. This would miss the boom arrangements and go to the Colorado. It may be there are now traces on the high water flow zone – have they addressed this? This is part of that warning I gave eary this spring about “gully washers” carrying this junk down. I mentioned it again at EAB in my report and Howard noted the flow over the bridge.
