WASHINGTON (CN) - California may use its own rules for controlling perchloroethylene from dry cleaning and water repelling operations in lieu of federal rules, according to a ruling by the U.S. Environmental Protection Agency.
California's jurisdiction will cover small source emitters, but major facilities that do contract cleaning will still have to adhere to federal rules.
Perchloroethylene can be harmful to humans: short term exposure causes dizziness, fatigue and headaches, while long term exposure can cause liver and kidney damage.
The chemical evaporates rapidly in the air but can be a major contributor to the combination of airborne pollutants that form smog.
