The Environmental Protection Agency's new changes to the Clean Air Act are likely to have the extra effect of causing some older coal-burning power plants to shut down. These plants, nearly all of which are over 50 years old, have been kept running due to loopholes in the Clean Air Act that allowed plants built before a certain time to continue running without restrictions.
This loophole was intended to allow plants on the verge of closing a few final years before shutting down, but many of them still run, without any air filters or environmental restrictions. The EPA's new restrictions will affect many of those plants, however, and cause the majority of them to shut down.
Opponents of the changes argue that the loss of jobs and energy this shutdown will cause is inexcusable, while those supporting the revisions tout statistics about how much cleaner the air would be without these high-pollution locations.
Either way, the shut downs will likely not go into effect until 2014, meaning that, for the time being, pollution will continue to to accumulate. If you want to keep these airborne toxins from your home, consider investing in a medical-grade air purifier. The powerful filtering technology will keep the air in your home safe for you and your family.
