Guam power plant no longer needs to prove it is cleaning up its sulfur pollution
What happened
US environmental regulators have decided that the air in Piti-Cabras, Guam, is clean enough. This means the local power plant no longer has to submit plans to reduce its sulfur dioxide emissions.
Why it matters
When an area is designated as having dirty air, local polluters must submit detailed plans to clean it up. This decision removes that requirement for the power plant in Piti-Cabras. It means the plant can continue operating without the regulatory pressure to invest in new pollution controls, as long as air quality stays within the standard.
The signal
Watch for any changes in air quality monitoring data for the Piti-Cabras area, or if the area is formally redesignated as having clean air.
