The Missouri Department of Natural Resources is responsible for safeguarding Missouri's water sources and protecting and improving the water quality. Companies doing business in Missouri may be subject to regulation under federal and state laws and regulations. Depending on the type of business, permits, certifications or fees may be required for protecting or improving Missouri’s waters.
The department issues a variety of water-related permits to ensure businesses and individuals understand and comply with all applicable provisions of federal and state environmental laws and regulations. Permits and certifications help keep the public safe by ensuring regulated water systems are properly constructed and maintained and emergency action plans are developed. They also help protect public health and the environment from the adverse effect of impaired waters.
The Water Preservation Act (Missouri Revised Statute 640.406, RSMo) takes effect on Aug. 28, 2025. For questions regarding water exportation permits, please contact the Water Resources Center at 573-751-2867 or by email at [email protected].
