Civil Enforcement FY 2023 Annual Results

EPA enforcement staff work diligently to protect human health and the environment, including working to mitigate the causes and effects of climate change, particularly for residents in communities that are overburdened by pollution. In FY 2023, the majority of inspections under EPA’s civil enforcement program and over half of its enforcement cases focused on communities overburdened by pollution and with potential environmental justice (EJ) concerns.  

EPA completed 1,791 enforcement cases, the highest number since FY 2018, and initiated nearly the same number of new cases. EPA's success in resolving noncompliance and reaching its environmental protection goals included successful collaboration with the Department of Justice and state partners in many of these cases. 

The 1,791 cases completed in FY 2023 resulted from violations and noncompliance with over a dozen environmental statutes, resulting in the following achievements: 

  • Commitments to reduce, treat, or eliminate over 73 million pounds of pollution.  
  • Proper treatment, minimization, or disposal of over 1.14 billion pounds of hazardous and non-hazardous waste.  
  • Commitments of over $3.8 billion to return facilities to compliance. 
  • Assessment of over $167 million in penalties. 
  • Conclusion of 77 judicial actions and continued oversight of nearly 400 judicial consent decrees. 
  • 44 settlements that included one or more supplemental environmental projects (SEP), bringing projects valued at over $13 million to communities and the environment.

Highlights of FY 2023 Significant Civil Enforcement Actions by Statute 

Clean Air Act  

The Williams Companies, Inc., MPLX LP, WES DJ Gathering LLC – Multiple state locations 

On April 20, 2023, EPA and DOJ, in partnership with the states of Alabama, Colorado, Louisiana, North Dakota, West Virginia, Wyoming, and the Southern Ute Tribe, settled three Clean Air Act (CAA) cases with multiple companies to adopt innovative emissions control standards and help increase additional emissions reductions across the industry. The three companies – The Williams Companies, Inc., MPLX LP, and WES DJ Gathering LLC (formerly known as Kerr-McGee Gathering LLC) operate gas processing plants and will pay a combined $9.25 million in penalties and spend approximately $16 million to install and operate new technologies, as well as improve and expand existing control techniques to minimize emissions.  

Additionally, the settlements will reduce thousands of tons of methane emissions, a greenhouse pollutant that is critical to EPA’s strategy for tackling the climate crisis. Along with helping to protect the public health in the communities where these facilities operate, the environmental benefits resulting from these three CAA agreements will reduce thousands of tons of criteria pollutants and significant amounts of hazardous air pollutants, which is the equivalent of the annual pollution from 11,267 gasoline-powered passenger cars.

Matador Production Company – New Mexico 

On March 27, 2023, the Matador Production Company reached a settlement with EPA and the state of New Mexico’s Environment Department (NMED) to pay a penalty and ensure compliance with both state and federal clean air regulations at all 239 of its New Mexico oil and gas well pads. Under the settlement, Matador will spend at least $2.5 million to implement extensive design, operation, maintenance and monitoring improvements, and pay a civil penalty of $1.15 million in addition to completing a supplemental environmental project involving diesel engine replacements.  

Matador’s noncompliance with the CAA resulted from failure to: 

  • Capture and control air emissions from storage vessels;  
  • Comply with inspection, monitoring, and recordkeeping requirements; and  
  • Obtain required state and federal permits at 25 of its oil and gas production operations in New Mexico.  

Matador’s future compliance with the CAA requirements will result in a reduction of more than 16,000 tons of air pollutants. These pollutants are key components in the formation of ground-level ozone, a pollutant that irritates the lungs, exacerbates diseases such as asthma, and can increase susceptibility to respiratory illnesses, such as pneumonia and bronchitis. The settlement will also result in significant reductions of greenhouse gas emissions, including methane, by more than 31,000 tons. These greenhouse gas reductions have a similar effect to eliminating the annual emissions of 6,060 gas-powered vehicles.

BP Whiting 

Under a May 17, 2023, CAA settlement agreement with BP Products North America Inc., (BPP), a subsidiary of BP p.l.c. related to national emission standard violations at its Whiting Refinery in Whiting , Indiana, BP will pay a $40 million civil penalty and commit to achieving emission reductions through capital investments estimated at $197 million. The settlement will result in reductions of benzene and other volatile organic compounds equivalent at the Whiting Refinery, which is surrounded by communities with potential EJ concerns. The $40 million penalty is the largest civil penalty secured for a stationary source CAA settlement. The settlement also includes a diesel emissions reduction SEP that requires BP to spend $5 million to replace diesel transportation vehicles with cleaner fuel vehicles (e.g., electric, clean diesel, propane, compressed natural gas) in the surrounding communities of Hammond, East Chicago, Whiting, and Gary, Indiana.

CAA - Greenhouse Gas Reporting Program 

Artsen Chemical America, Harp USA, and IGas Companies 

To combat climate change, the civil enforcement program completed several enforcement actions that support national and international goals to reduce the use of hydrofluorocarbons (HFCs), which are commonly used in refrigeration and air conditioning equipment. HFCs are potent greenhouse gases that can have impacts on the climate hundreds to thousands of times greater than the same amount of carbon dioxide (CO2). These civil penalty actions include three landmark settlements with HFC importers who failed to report their imported quantities in violation of the Clean Air Act’s Greenhouse Gas Reporting Program: Artsen Chemical America, LLC ($247,601 penalty), Harp USA, Inc. ($275,000 penalty), and the IGas Companies ($382,473 penalty). Accurate data and reporting of greenhouse gas (GHG) emissions are critical to effectively tailoring EPA’s efforts to tackle the climate crisis.

Nationwide Cases to Reduce Chemical Accident Risks  

In FY 2023 EPA reached settlement on two nationwide cases under Clean Air Act (CAA) Section 112(r), a law designed to help prevent chemical accidents at facilities using substances that pose the greatest risk of harm from accidental releases.  

Anheuser-Busch, LLC – Multiple state locations 

On June 2, 2023, EPA and Anheuser-Busch, LLC reached settlement to improve safety at its 11 flagship breweries nationwide and provide increased
