Federal Environmental Regulations (40 CFR)

The regulations adopted by the Arkansas Pollution Control and Ecology Commission are the basis for ADEQ's environmental permitting, monitoring and enforcement, public involvement activities and other services.

Most Arkansas regulations are based on national environmental laws (acts of Congress) and national environmental regulations found in the U.S. Code of Federal Regulations (CFR). For simplicity, some Arkansas regulations adopt federal regulations by reference.

The U.S. Environmental Protection Agency’s major effluent limitation guidelines are available at the Industry Effluent Guidelines webpage. For an overview of effluent regulation, go to Industrial Regulations and scroll down to the “Industry Category” column. The effluent guidelines promulgated by EPA are sorted alphabetically by industry category.
