The Maryland Department of Agriculture is a member of the National Network on Water Quality Trading. In June 2015, that group published a comprehensive reference providing the essential tools for new and evolving water quality trading programs. “Building a Water Quality Trading Program: Options and Considerations” identifies common trading issues and the options, considerations, and examples important to building a trading program. It captures several decades of experience in trading programs and is the product of a dialogue between National Network participants who represent agriculture, wastewater utilities, environmental groups, regulatory agencies, and practitioners.
