The court upheld the state's authority to impose stricter air quality standards, emphasizing the need for empirical data to justify regulatory actions.
This ruling reaffirmed Delaware's right to enforce environmental regulations, placing the burden on the agency to prove the relevance of its limits on emissions.
In this case, the court supported the agency's decision-making process under the Clean Air Act, affirming that reasonable regulation is permissible when justified by environmental data.
