KY SB178

Environmental regulations in Kentucky cannot be more stringent than corresponding federal laws or regulations on the same topic

Where no federal law exists, environmental regulations can only be adopted if supported by "best available science" and "weight of scientific evidence," and must be technologically achievable

Health-based regulations must demonstrate a "direct causal link" between exposure levels and "manifest bodily harm" (defined as presently existing, diagnosable physical disease or injury—not merely substance detection or increased risk)

Exemptions include regulations required by federal law, regulations that are less stringent than federal standards, regulations being repealed or weakened, and emergency regulations

Applies to regulations under KRS Chapters 39E, 109, 146, 151, 211, 224, and 350 (covering emergency management, mining, water resources, public health, and environmental protection)
