EPA throws in the towel on policing air pollution from factory farms
Critics say EPA is effectively abandoning Clean Air Act enforcement at factory farms.
The Environmental Protection Agency late last week announced it would end a 20-plus-year effort to develop methods to monitor air pollution from factory farms, effectively shuttering the agency’s stop-and-start attempts to regulate the potentially pollutant-spewing facilities under the Clean Air Act.
The announcement came just days before the midterm elections and was characterized by the agency as a long-awaited reprieve for farmers, a historically important constituency for Trump and the Republican Party.
When tens of thousands of animals are packed into one place, pollution from their waste is blown from ventilation fans or emanates from giant lagoons of liquid effluent. Livestock facilities emit fine particulate matter, ammonia, nitrogen oxides, sulfur dioxide, and volatile organic compounds, all contributing to a toxic mix. Research has shown that emissions from these operations are a major cause of air pollution, causing nearly 12,700 deaths in the United States a year.
