Summary of the Legal Basis:




Anticipated Costs and Benefits:

EPA believes the benefits of the rule will justify the costs. The benefits of EPA ensuring that data and models underlying pivotal science are available in a manner sufficient for independent validation are that it will improve the data and scientific quality of the Agency's assessments that support the CAA and CAA actions and facilitate expanded data sharing and exploration of key data sets.



This rulemaking will not directly address risks, it will increase transparency in the use of science in influential scientific information and final significant regulatory actions that address risks under the CAA.
