(26) Marketplace means an online system where information is exchanged between credit owners or their representatives and credit buyers.
(27) Maryland Nutrient Tracking Tool (MNTT) means an online performance-based calculation system that enables users to analyze agricultural parcels and their management to determine eligibility and credit generation potential for participation in the Maryland Water Quality Trading Program.
(28) Maryland Water Quality Trading Program (Program) means the Program under this chapter that establishes the policies and procedures to support market-based trading activities to enhance water quality and to certify, verify, and register nonagricultural point and nonpoint source nitrogen, phosphorus, and sediment credits.
(29) MS4 Permittee means a person that has been issued a Phase I MS4 permit or a Phase II MS4 permit as defined in 40 CFR §122.26.
