MoreOn Tuesday, Jan. 5, 2009, the EPA held a public hearing on the agency's proposal to strengthen the nation's SO2 standards. The agency is taking comment on a proposal to establish a new national one-hour SO2 standard, between 50 and 100 parts per billion. Because the revised standards would be more protective, the EPA is concurrently proposing to revoke the current 24-hour and annual SO2 health standards.
The agency will continue to accept written comments on the proposed rule until Feb. 8, 2010.
