I got the article in an email and couldn’t find it on the internet without a subscription. Here’s a taste:
Several environmental, public health, and community organizations have asked the Environmental Protection Agency to formally list hydrogen sulfide as a hazardous air pollutant subject to regulation under the Clean Air Act.
“It’s time for the EPA to take action to formally acknowledge hydrogen sulfide’s clear toxicity at low concentrations,” the groups wrote March 30 in a letter to EPA Administrator Lisa Jackson. “As administrator, you have CAA authority under section 112(b)(2) to act based on a pollutant that poses or may pose ‘a serious threat of adverse health benefits.’ “
The letter also calls on EPA “to require annual reporting of H2S as a toxic substance under the Toxics Release Inventory (TRI) reporting program.”
According to the letter, “EPA needs a TRI reporting threshold of 1.0 pound for H2S and not 10,000 pounds as was originally the requirement.”
The letter was signed by representatives of the Sierra Club, Citizens for Environmental Justice, Earthjustice Legal Defense Fund, Environmental Integrity Project, and several other organizations.
