Report, Nitrogen Management Project Protocol

Provides guidance on how to quantify, monitor, and verify greenhouse gas emission reductions from improving nitrogen use efficiency in crop production.

New Hampshire Fertilizer Rules

New Hampshire sets nitrogen concentration limits for different types of fertilizer.

New Jersey Fertilizer Rules

New Jersey prohibits the sale of fertilizer that exceeds certain limits for nitrogen concentration.

Chesapeake Bay Watershed Implementation Plans

Several states’ watershed implementation plans encourage farmers to adopt best practices including cover crops, forest buffers, and nutrient management plans.

Delaware State Nutrient Management Law

The Delaware State Nutrient Management Law requires farmers prepare nutrient management plans, which must limit nitrogen application to the expected yield of the specific crop.

Maine Nutrient Management Act

Maine’s Nutrient Management Act bans winter manure spreading from December 1st through March 15th, which reduces aeration of nitrous oxide.

Maryland Nutrient Management Law

Fertilizer may not be applied to frozen ground, which reduces aeration of nitrous oxide, and various application rate limits for fertilizer are specified.

SF6 Emission Reduction Partnership for Electric Power Systems

Works with utilities to voluntarily commit to reduce sulfur hexafluoride emissions. The Partnership published a 2018 report detailing technical lessons learned from the partnership.

GreenChill Partnership

EPA’s GreenChill Partnership with food retailers, technology manufacturers, and chemical manufacturers works to reduce refrigerant emissions and transition to environmentally safe refrigerants.
