EPA again blocks Colorado air pollution permit for Suncor

The EPA Blocks Renewal of Suncor Refinery’s Air Pollution Permit

The EPA’s Denver regional office is once again blocking a renewed state air pollution permit for the Suncor refinery in Commerce City, agreeing to objections from environmental groups that Colorado should crack down harder on carbon monoxide dangers and past plant modifications. 

Background

• Suncor has had numerous air and water pollution violations in recent years.
• The regional Environmental Protection Agency had objections to Suncor permit renewals last year.
• After Colorado issued revisions, neighbors and environmental groups had the chance to make new objections.

While Suncor’s Plant 2 will be allowed to continue producing petroleum products for Colorado and the region, state air pollution officials must now “resolve EPA’s objections” based on the environmental groups’ two petitions “before issuing a revised permit.” 

EPA’s Commitment to Environmental Justice

“Improving air quality for the underserved communities affected by harmful air emissions from the Suncor refinery is a shared priority for EPA and CDPHE,” said EPA Regional Administrator KC Becker. Becker is the former Democratic Speaker of the House for Colorado, and has placed an emphasis on carrying out environmental justice initiatives while at the EPA. 

 “EPA will continue to work with Colorado to secure the refinery’s compliance with laws and regulations and protect the health of nearby residents,” Becker said.  

Environmental Groups’ Response

• Representatives of the environmental groups welcomed the new scrutiny on Suncor.
• They have demanded intensified state scrutiny of the refinery as it seeks permit renewals.
• Some have called for the outright closure of the sprawling plant, the only petroleum refinery in Colorado.

“We’re grateful the EPA is taking the concerns of community and community-based organizations seriously, but fines aren’t working with these people,” said Ean Tafoya, director of the nonprofit Colorado GreenLatinos, one of the petitioners. “We’ve said for a very long time Suncor continues to be out of compliance, and enforcement isn’t enough, they just keep paying to play. It’s time for us to begin planning the closure of Suncor.” 

“We are happy that the EPA took an important step toward holding Suncor accountable for its toxic air pollution,” said Ian Coghill, senior attorney with Earthjustice. “For too long, impacted communities have suffered at the hands of the refinery and the state has failed to hold it accountable. This must result in the state taking a meaningful look at Suncor’s permitting and finally reining in its pollution.”

Impact on the Local Economy

Coloradans managed while the entire refinery was shut down for repairs early in 2023 after a fire, Tafoya said. “The local economy survived. We’re grateful we have these tools and the EPA appears to be listening,” he said. 

Next Steps

The EPA’s demands in effect reset the clock on assessing Suncor’s expired permit, which has been under scrutiny for years. Depending on how much the Colorado Department of Public Health and Environment rewrites the Plant 2 permit, the EPA said, “the revisions may involve additional public notice and comment.” The EPA would have 45 days to review how the state handled EPA objections, then the public would have another 60-day petition period to make new objections.

Suncor first sought to renew the Plant 2 permit in 2010. The state allows some industries to keep operating under expired permits, and says it enforces the requirements of the old permit in the meantime.

The EPA’s order directs Colorado officials to “evaluate whether additional operational requirements are needed to assure compliance with carbon monoxide and opacity limits at the plant’s fluid catalytic cracking unit. It also directs CDPHE to determine whether previous plant modifications were analyzed properly.” 

Tuesday afternoon, state air pollution officials said they were “closely reviewing” the EPA’s decision to grant parts of the petitions to the permit. “The division will decide how to proceed after its review of the EPA’s decision and documentation,” said a spokesperson for the Air Pollution Control Division.

Environmental Groups’ Demands

The EPA’s 99-page summary of its partial agreements with the petitioners appears to lean toward new standards for Suncor, Tafoya said. Environmental groups want the state to require technology upgrades at Suncor that would prevent leaks, including demands to use the “best available technology.” 

Given months of news about benzene, sulfur dioxide and other hazardous material releases, Tafoya said, “GreenLatinos wants to have a meeting with the state about cumulative violations.” 

Role of the EPA and State Officials

Under the U.S. Clean Air Act, the EPA sets regulations on air pollution limits, and state officials carry out the permitting, inspection, and enforcement on the companies receiving permits. 

EPA’s Announcement

The EPA announcement Tuesday said “one petition was filed by Earthjustice on behalf of the Elyria and Swansea Neighborhood Association, Cultivando, Colorado Latino Forum, GreenLatinos, Center for Biological Diversity and Sierra Club. The second petition was filed by 350 Colorado.” The 350 Colorado petition was denied, the EPA said, but many of the objections in the petition filed by Earthjustice were validated. 

 “EPA is also supporting community-based air monitoring and state-led efforts to investigate and address noncompliance issues associated with air emissions from the Suncor plants,” the EPA office said.

SDGs, Targets, and Indicators

1. SDG 3: Good Health and Well-being

   • Target 3.9: By 2030, substantially reduce the number of deaths and illnesses from hazardous chemicals and air, water, and soil pollution and contamination.
   • Indicator: The article mentions that Suncor has been releasing excessive levels of dangerous materials like benzene, PFAS “forever chemicals,” sulfur dioxide, and more into the air and water. These pollutants pose health risks to nearby residents.

2. SDG 6: Clean Water and Sanitation

   • Target 6.3: By 2030, improve water quality by reducing pollution, eliminating dumping, and minimizing release of hazardous chemicals and materials.
   • Indicator: The article mentions that Suncor has had numerous water pollution violations in recent years. The excessive release of dangerous materials into the water poses a threat to water quality.

3. SDG 11: Sustainable Cities and Communities

   • Target 11.6: By 2030, reduce the adverse per capita environmental impact of cities, including by paying special attention to air quality and municipal and other waste management.
   • Indicator: The article highlights the concerns of community members and environmental groups regarding the air pollution caused by Suncor’s refinery. The excessive release of dangerous materials into the air affects air quality in the surrounding communities.

4. SDG 13: Climate Action

   • Target 13.2: Integrate climate change measures into national policies, strategies, and planning.
   • Indicator: The article mentions that environmental groups are demanding intensified state scrutiny of the refinery as it seeks permit renewals. This suggests a need for stronger regulations and policies to address the refinery’s contribution to climate change.
