In a hearing today on Capitol Hill, Lisa Jackson, Administrator of the US Environmental Protection Agency testified before the Senate Environment and Public Works Committee regarding EPAs ability to limit chemical contaminants in drinking water.
Especially contentious are the chemicals perchlorate and chromium 6. According to Jackson’s testimony, “EPA is evaluating the opportunity for health risk reductions from unregulated contaminants such as perchlorate, and reviewing existing standards, such as chromium, to determine if public health protections can be improved.”
Jackson announced just before the hearing that EPA will issue new federal regulations on perchlorate, reversing a George W. Bush-era decision not to regulate the chemical, which is used to make rocket fuel and explosives.
Barbara Boxer, the Chair of the Senate Committee applauded the EPA for moving forward to establish a national drinking water standard for perchlorate. According to a Government Accountability Office report cited in Boxer’s opening remarks, in the absence of a federal regulatory standard for perchlorate in drinking water, California and Massachusetts have adopted their own standards. California adopted a drinking water standard of 6 parts per billion in 2007, and Massachusetts set a drinking water standard of 2 parts per billion in 2006.
The report also points out that perchlorate has been found in water and other media at varying levels in 45 states, as well as in the food supply, and comes from a variety of sources.
According to EPA, chromium is found in over 60 cleanup sites in the state of Massachusetts alone.
Despite the important topic of safe drinking water and limiting chemical exposure that would otherwise impact public health, GOP Senators preferred to discuss their dislike for protecting the public from other pollutants, namely those that will impact the global climate. Wyoming Republican John Barrasso was quoted during the hearing as saying that “EPA has continued to move forward with job-crushing greenhouse gas regulations for greenhouse gases.”
The rhetoric spun by Barrasso and other Tools of the oil industry is part of an effort to limit the EPA’s authority to regulate greenhouse gas emissions. Barrasso, James Inhofe, the Senate’s lead contrarian to anything climate related, and Michigan Rep. Fred Upton have all introduced legislation limiting EPA’s ability to regulate these pollutants. (Upton, who now chairs the House Energy and Commerce Committee, will reportedly introduce legislation some time today.)
Jackson defended EPA’s action. “These efforts would halt EPA’s commonsense steps under the Clean Air Act to protect Americans from harmful air pollution that until now has not been regulated at all from any sources in this country,” Jackson told reporters after the hearing.
Discussions of chemical safety laws will continue with a senate subcommittee hearing tomorrow.
