EPA’s proposed TSCA rule to limit risks from chrysotile asbestos uses a higher “acceptable” cancer risk for workers than the rest of the population

When it comes to drawing the line on cancer risks, should workers be treated differently than the general population? Of course not. Unfortunately, EPA’s recently proposed rule to manage risks from chrysotile asbestos does just that, using one level of acceptable risk for workers and another – more protective threshold – for everyone else.
EPA says it uses a range for determining acceptable cancer risks under the Toxic Substances Control Act (TSCA), the country’s main chemical safety law. The range spans a risk (or the chance that a person will develop cancer) of less than one in 10,000 to a risk of less than one in one million. EPA says this is consistent with the cancer benchmark used by the National Institute for Occupational Safety and Health (NIOSH).
However, EPA’s proposed TSCA rule for asbestos does not actually use a range and it is not supported by TSCA. EPA instead applies a risk level to workers 100 times less protective than for everyone else! Read More
