Congress finds the following:
(1)
Since 1992, the Environmental Protection Agency (hereinafter referred to as the “EPA”) has prohibited the use of phosphogypsum in road construction, citing numerous scenarios that would expose the public, and especially road construction workers, to an unacceptable risk of cancer.
(2)
EPA prohibited use of phosphogypsum in roads because it contains uranium and radium that produce radionuclides linked to higher risks of cancer and genetic damage. The Clean Air Act was amended in 1977 after finding that exposure to radioactive materials can cause serious harm to health, and that exposures to radioactivity are cumulative, which means each new or additional exposure increases the risk of serious illness.
(3)
EPA found that phosphogypsum used in roads could contaminate nearby surface and groundwater quality through leaching, and that radioactive material could be resuspended into the air by wind and vehicle traffic.
(4)
EPA found that stacking of phosphogypsum presented a lifetime cancer risk of 9.1 in 100,000, meaning that any alternative distribution of phosphogypsum must meet this same protective threshold.
(5)
The Director of EPA’s Office of Radiation and Indoor Air has testified that use of phosphogysum as “road building material could not meet the EPA’s risk criteria”.
(6)
EPA has further acknowledged it cannot authorize categorical approvals and requires case-by-case consideration of other uses.
