EPA revises Clean Air Standards for stationary engines

In compliance with settlement agreements, the U.S. Environmental Protection Agency (EPA) finalized revisions to standards to reduce air pollution from stationary engines that generate electricity and power equipment at industrial, agricultural, oil and gas production, power generation and other facilities.

The final revised rule will reduce the capital and annual costs of the original 2010 rules by $287 million and $139 million, respectively, while reducing harmful pollutants, including 2,800 tons per year (tpy) of hazardous air pollutants; 36,000 tpy of carbon monoxide; 2,800 tpy of particulate matter; 9,600 tpy of nitrogen oxides, and 36,000 tpy of volatile organic compounds.

According to EPA, pollution emitted from the engines can cause cancer and other serious health effects including: aggravation of respiratory and cardiovascular disease; premature deaths in people with heart or lung disease; neurological, cardiovascular, liver, kidney health effects; and effects on immune and reproductive systems.

EPA estimates annual health benefits of the updated standards to be worth $830 million to $2.1 billion.

The final amendments to the 2010 “National Emission Standards for Hazardous Air Pollutants for Reciprocating Internal Combustion Engines (RICE)” reflect new technical information submitted by stakeholders after the 2010 standards were issued. The updates will ensure that the standards are cost-effective, achievable, and protective, while continuing to provide significant emission reductions.

The amendments also specify how the standards apply to emergency engines used for emergency demand response.
