7.3.7 Reducing Agricultural Emissions through Source Regulation

LPDD Recommendation: “EPA should consider imposing regulatory methane emissions limits for concentrated animal facilities.”

LPDD Recommendation: “EPA should impose emissions limitations on both conventional pollutants and GHG emissions from fertilizer production.”

LPDD Recommendation: “EPA should strengthen its nationwide NPDES regulations in ways that would reduce GHG emissions as well as water pollution.”

LPDD Recommendation: “EPA should use its regulatory tools for hazardous air emissions to also reduce methane and nitrous oxide emis­sions from agriculture.”

LPDD Recommendation: “Congress should ensure that government financial incentive and regulatory programs do not support large-scale operations without also requiring them to curb their most environmentally damaging practices.”

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.

Minnesota Vegetative Buffer Requirements

A pioneering law requiring permanent vegetative buffers on farmland abutting lakes and streams. The law was designed to reduce runoff, but will also increase soil carbon sequestration on the new strips.

California Short-Lived Climate Pollutant Strategy

Calls for development of a comprehensive strategy to reduce short-lived climate pollutants, including methane. CARB’s strategy calls for significant decreases in emissions from dairy manure management.
