28 years since the last chemical risk assessment


When the law was passed allowing the EPA to do risk assessments on commonly used chemicals, those in use at the time were all grandfathered from review unless proven to be harmful. Since then the EPA has just finished its first risk assessment in 28 years on the chemical solvent trichloroethylene (TCE).
At issue is the Toxic Substances Control Act (TSCA), the 38-year-old legislation that guides the EPA’s chemical review process. The EPA says the law is “badly in need of modernization,” and most lawmakers, chemical industry stakeholders and environmental experts agree.

The law essentially says that any chemical in use before the TSCA was passed is considered safe until proven otherwise and can be used without EPA oversight. That amounts to 62,000 chemicals, according to the EPA.

The EPA says the TSCA is the only major environmental law that has not been modernized.

The EPA and environmentalists contend that there are thousands of potentially dangerous chemicals in widespread use today. They can be found in everything from agricultural products like fertilizers to flame retardants that are used on things like airplane seats and kids’ toys.

The EPA could begin reviewing chemicals without a specific mandate to do so, and that’s exactly what it’s begun doing: TCE is one of 83 chemicals the agency has identified as posing possible risks to human health, and therefore in need of prompt risk assessments.

But without a legal mandate, the EPA says it doesn’t have enough staff or funding to carry out reviews in a timely manner, and doesn’t have the authority to require companies to hand over data on potentially harmful chemicals.

It picked TCE for its first risk assessment in nearly three decades essentially because it was low-hanging fruit.

“TCE is a good first candidate, because unlike most chemicals, EPA has a significant amount of data on the substance,” Jones wrote.

Without data on other chemicals, and with new chemicals entering the marketplace at a rapid rate, experts warn that the EPA is bound to fall further and further behind on its workload.

“There are thousands of chemicals used widely that have never been studied or proven safe,” said Richard Denison, a lead scientist at the Environmental Defense Fund. “We’ve dug ourselves in a very deep hole here.”

Denison said that, given the amount of chemicals out there, even if Congress passed a law mandating that the EPA start an extensive review process tomorrow, it would be decades before the agency worked through its backlog.
The makers and users of all those chemicals could be profitably poisoning us and we don't know it. And since any law has to pass a corporate controlled Congress, please be advised that holding your breath is not a good idea.

Comments:
The best way to reduce the risk of costly chemical accidents threatening your business is to put in suitable control measures to stop them happening in the first place. Control of Substances Hazardous to Health (COSHH) regulations is very effective to save the health and also life of the workers doing chemical work.
