Most commercial and industrial businesses will be inspected by the Environmental Compliance Division to ensure businesses are implementing Best Management Practices (BMPs). BMPs are activities or engineered systems that prevent pollutants generated from business activities from being washed off site when it rains. More information on BMPs for specific businesses can be found in these brochures:
