On March 26, the newest version of the baseline and credit calculation tool (Maryland Nutrient Tracking Tool or MNTTv.2) will be released on this website. All existing accounts and projects will be available on the new version. Anyone wishing to use assessments from the current version for submissions to either the Certainty or Agricultural Credit Certification Program will need to re-run them using the latest version since the results will differ.

The current version will be archived for those with existing Certainty assessments, and access will be granted upon request to the Maryland Department of Agriculture (MDA).

National Network on Water Quality Trading

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.
