Toxic Chemical Exposure Reduction Act of 2008 or the TCE Reduction Act of 2008 - Amends the Safe Drinking Water Act to require the Administrator of the Environmental Protection Agency (EPA) to publish a health advisory, including cancer risks, for trichloroethylene that fully protects, with an adequate margin of safety, the health of susceptible populations (including pregnant women, infants, and children), taking into consideration body weight, exposure patterns, and all routes of exposure.
Requires the Administrator to promulgate a national primary drinking water regulation for trichloroethylene: (1) that is protective of susceptible populations; and (2) the maximum contaminant level of which is as close to the maximum contaminant level goal for trichloroethylene, and as protective of those susceptible populations, as is feasible.
Requires consumer confidence reports to disclose the presence of, and the potential health and cancer risks to susceptible populations from exposure to, trichloroethylene in drinking water.
Requires the Administrator to: (1) publish a health advisory (including cancer risks) for trichloroethylene that fully protects the health of susceptible populations from vapor intrusion; (2) establish an integrated risk information system reference concentration of trichloroethylene vapor that is protective of susceptible populations; and (3) apply such reference concentration with respect to any potential vapor intrusion-related investigations or actions to protect public health with respect to trichloroethylene exposure carried out pursuant to the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 and the Safe Drinking Water Act.
