Frank R. Lautenberg Chemical Safety for the 21st Century Act

TSCA Modernization Act of 2015 This bill amends the Toxic Substances Control Act (TSCA) to revise regulations on chemicals. TSCA's scope is revised by requiring the Environmental Protection Agency (EPA) to regulate chemicals so that they no longer present unreasonable risks of injury to health or environment instead of requiring the EPA to provide adequate protection against those risks using the least burdensome requirements. The EPA must conduct and publish a risk evaluation for a chemical if: (1) the EPA determines it may present an unreasonable risk of injury to health or the environment, or (2) a manufacturer of a chemical requests an evaluation. The EPA must initiate 10 or more risk evaluations in each fiscal year. The EPA is authorized to require testing on a chemical when it is necessary to conduct an evaluation. If an evaluation determines a chemical will pose an unreasonable risk, the EPA must issue a risk management rule for the chemical. The bill establishes deadlines for conducting and publishing evaluations as well deadlines for publishing risk management rules. The EPA may grant exemptions from risk management requirements for a specific use of a chemical if: (1) the requirement is not cost-effective with respect to that use; and (2) the specific use is a critical or essential use, or the requirement would significantly disrupt the national economy, national security, or critical infrastructure. The EPA must: (1) publish a list of certain persistent, bioaccumulative, and toxic (PBT) chemicals; (2) designate certain chemicals as PBT chemicals of concern; and (3) promulgate rules with respect to those designated PBTs to reduce likely exposure to the extent practicable. This bill revises requirements concerning the disclosure of confidential business information, preemption of state law, fees to defray the cost of administering TSCA, and scientific standards and evidence.
