The Oil and Gas Watch database, created by Environmental Integrity Project (EIP), is a free, public-facing tool designed to track the rapid expansion of fossil fuel and petrochemical infrastructure in the United States. Oil and Gas Watch maps new and expanding oil, gas, and petrochemical infrastructure projects across the country and monitors each project’s construction status so the public can stay informed about major oil and gas developments being proposed in their communities. We track key environmental approvals companies must obtain before starting construction or operations and provide access to thousands of government records and permits unearthed by our analysts.

Background

Tolk Station was commissioned in 1982 by Southwestern Public Service Company (SPS), a subsidiary of Xcel Energy. The power station serves customers in Texas and New Mexico.[7]

Retirement plans

In 2020, the Sierra Club agreed with SPS to close the plant by the end of 2032 and assess the option of an earlier retirement based on the power station's operating costs and its significant role in depleting the Ogallala Aquifer.[8]

In October 2023, the New Mexico Public Regulation Commission voted in favor of an agreement with SPS to bring forward the closure of Tolk Station from 2032 to 2028. The agreement also required SPS to only operate the plant when it economically benefits customers.[9][10]

In May 2026, the New Mexico Public Regulation Commission approved SPS’s request to delay the retirement of coal units at Tolk to March 2029.[11]

Death and disease attributable to fine particle pollution from Tolk Station

In 2010, Abt Associates issued a study commissioned by the Clean Air Task Force, a nonprofit research and advocacy organization, quantifying the deaths and other health effects attributable to fine particle pollution from coal-fired power plants.[15] Fine particle pollution consists of a complex mixture of soot, heavy metals, sulfur dioxide, and nitrogen oxides. Among these particles, the most dangerous are those less than 2.5 microns in diameter, which are so tiny that they can evade the lung's natural defenses, enter the bloodstream, and be transported to vital organs. Impacts are especially severe among the elderly, children, and those with respiratory disease. The study found that over 13,000 deaths and tens of thousands of cases of chronic bronchitis, acute bronchitis, asthma, congestive heart failure, acute myocardial infarction, dysrhythmia, ischemic heart disease, chronic lung disease, and pneumonia each year are attributable to fine particle pollution from U.S. coal plant emissions. These deaths and illnesses are major examples of coal's external costs, i.e. uncompensated harms inflicted upon the public at large. Low-income and minority populations are disproportionately impacted as well, due to the tendency of companies to avoid locating power plants upwind of affluent communities. To monetize the health impact of fine particle pollution from each coal plant, Abt assigned a value of $7,300,000 to each 2010 mortality, based on a range of government and private studies. Valuations of illnesses ranged from $52 for an asthma episode to $440,000 for a case of chronic bronchitis.[16]

Type of Impact Annual Incidence Valuation
Deaths 15 $110,000,000
Heart attacks 23 $2,600,000
Asthma attacks 260 $14,000
Hospital admissions 11 $260,000
Chronic bronchitis 9 $4,200,000
Asthma ER visits 15 $6,000
