A House Transportation and Infrastructure panel this week will discuss regulating anti-fouling paint, a material that prevents algae and barnacles from growing on ships' hulls but that can be toxic to marine life.
The Senate in September ratified an international treaty banning the use of harmful chemicals in anti-fouling paints, but Congress has yet to pass legislation that would allow U.S. regulators to enforce the provision.
Stephen Johnson, U.S. EPA administrator under the Bush administration, sent a legislative proposal on the matter to Congress in February 2008. The Subcommittee on Coast Guard and Maritime Transportation on Wednesday will review the proposal and ensure it aligns with the views of the Obama administration, a House Democratic aide said.
The hearing will also "address the lessons learned from the past and how [the treaty] will address the safety of hull paints in the future," according to the committee.
Officials from EPA and the Coast Guard -- the agencies that would enforce the provision -- have been invited to testify.
The accumulation of mollusks and algae on ships' hulls can have significant economic impacts, slowing vessels down and increasing their fuel consumption.
Anti-fouling paints contain pesticides that prevent the organisms from latching on, but the metallic compounds in many of the paints linger in the water, damaging the environment, killing other sealife and possibly entering the food chain, according to the International Maritime Organization, the United Nations agency that initiated the treaty.
One of the most popular anti-fouling paints contains the compound tributyltin, which has been shown to cause deformities in oysters and sex changes in whelks. The treaty prohibits the use of the compound and mandates the removal of the paints from hulls.
Ships may use alternative paints that do not contain the compound, or slippery, biocide-free nonstick coatings that prevent fouling and make the hull easier to clean when fouling occurs, IMO said.
Schedule: The hearing is Wednesday, June 10, at 2 p.m. in 2167 Rayburn.
Witnesses: TBA.
