[USA] Apache Corporation (Apache) has agreed to pay $4 million in civil penalties and undertake projects expected to cost at least $5.5 million to ensure 422 of its oil and gas well pads in New Mexico and Texas comply with federal and state clean air regulations and offset past illegal emissions.
Apache’s agreement settles a civil suit, filed jointly by the United States, on behalf of the Environmental Protection Agency (EPA) and the New Mexico Environment Department (NMED), alleging that Apache failed to comply with federal and state requirements to capture and control air emissions from 23 of its oil and gas production operations in New Mexico and Texas. EPA and NMED identified the alleged violations through field investigations and repeated flyover surveillance conducted in 2019, 2020 and 2022.
Compliance with this robust settlement will result in annual reductions of more than 9,650 tonnes of Volatile Organic Compounds (VOCs) and 900 tonnes of methane, which equates to more than 25,000 tonnes of carbon dioxide (CO2). VOCs are a key component in the formation of ground-level ozone or smog, which irritates lungs, exacerbates diseases including asthma and can increase susceptibility to respiratory illnesses, such as pneumonia and bronchitis.
The $4 million fine outlined in the settlement will be shared equally by the United States and the State of New Mexico, with New Mexico’s portion going to the state’s general fund. The settlement document (consent decree) was filed together with the complaint in the U.S. District Court for the District of New Mexico and requires the company to take numerous steps to ensure that 422 well pads covered by the consent decree and located in New Mexico and Texas are operated lawfully.
In addition to the $4 million fine, Apache will also spend at least $4.5 million to implement extensive design, operation, maintenance, and monitoring improvements, including installing new tank pressure monitoring systems that will provide advance notification of potential emissions and allow for immediate response action by the company. Apache will also spend over $1 million to offset the harm caused by the alleged violations by replacing, on an accelerated schedule, more than 400 pollutant-emitting pneumatic devices with non-emitting devices.
The Clean Air Act requires the EPA to set National Ambient Air Quality Standards (NAAQS) for criteria pollutants that are considered harmful to public health and the environment. Ozone is a criteria pollutant that is created when oxides of nitrogen (NOx) and VOCs react in the atmosphere. VOCs and NOx are emitted by oil and gas production facilities, such as those operated by Apache. During the timeframes of Apache’s alleged violations, air quality monitors in the relevant counties in New Mexico registered rising ozone concentrations exceeding 95% of the NAAQS for ozone. In counties where ozone levels reach 95% of the NAAQS, NMED is required by New Mexico state statute to take action to reduce ozone pollution.
The Justice Department’s Environmental Enforcement Division lodged the proposed consent decree in the U.S. District Court for the District of New Mexico. The settlement is subject to a 30-day public comment period and final court approval.
