Isle plants named top polluters
Two Big Isle power plants were among the state’s top 10 chemical polluters in 2011, according to a list released Wednesday by the U.S. Environmental Protection Agency.
Meanwhile, the U.S. Army’s Pohakuloa Training Area was again named one of the top 10 sites in Hawaii responsbile for on-site and off-site releases of PBT chemicals — “persistent bioaccumulative toxic” chemicals that are of particular concern not only because they are toxic, but because they remain in the environment for long periods of time, are not readily destroyed, and build up in body tissues.
Hawaii Electric Light Co.’s Hill Generating Station on Railroad Avenue was the state’s eighth-largest polluter with a reported 160,033 pounds of toxic chemicals, mostly sulfuric acid.
HELCO’s Puna Generating Station came in at No. 10, generating 65,011 pounds of the toxic chemicals.
The Army’s PTA site took the third spot in the state on a separate top 10 list for PBT releases, generating 13,760 pounds of PBTs.
According to the EPA, 36 Hawaii facilities reported a total of 2.6 million pounds of toxic chemical releases during 2011. The state’s total reported on-site and off-site releases increased 4 percent, or 101,000 pounds, when compared to 2010 data.
Meanwhile, 77,000 pounds of total PBT chemical releases were reported in 2011. This marked a decrease of 18,000 pounds, or 19 percent, since 2010.
