"Agency is accepting public comments through June 29 on proposed regulations that supporters say would help protect the environment".
"The U.S. Environmental Protection Agency is accepting public comments until June 29 on proposed revisions to emission standards for mining operations that process taconite, a low-grade iron ore.
The EPA estimates the standards will reduce mercury emissions by approximately 57 percent — mercury emissions were not included in emission standards adopted 20 years ago — and will further reduce hydrogen chloride and hydrogen fluoride emissions.
Hydrogen chloride and hydrogen fluoride emissions are acid gasses that have been demonstrated to cause adverse health effects, including “chronic and acute disorders of the blood, heart, kidneys, reproductive system, respiratory system and central nervous system,” the EPA reported.
Several tribal nations and the environmental law organization Earthjustice welcomed the mercury emission standards — they sued EPA to set the limits — but say the standards don’t go far enough to protect the environment and human health."
