Agricultural Air Emissions

Documents on this page require Adobe Acrobat.

People, livestock, plants, automobiles, etc. all contribute collectively to our emissions problem. EPA has set standards for states to meet and has designated “non attainment” areas for counties that are currently exceeding those standards. Twenty-four of Pennsylvania's counties currently do not meet these standards for fine Particulate Matter (PM2.5) or 8 hour Surface Ozone (O3). The counties EPA listed for non-attainment in PA include: Allegheny, Armstrong, Beaver, Berks, Bucks, Butler, Cambria, Chester, Cumberland, Dauphin, Delaware, Fayette, Greene, Indiana, Lancaster, Lawrence, Lebanon, Lehigh, Montgomery, Northampton, Philadelphia, Washington, Westmoreland, and York.

Conservation Practices That Help Reduce Agricultural Air Emissions or Odors:

  • Nutrient Management – injection of manure, nitrification and urease inhibitors

  • Feed Management

  • Manure Amendments and Treatments

  • Manure Storage, Collection and Handling – digesters, waste treatment, composting facilities

  • Windbreaks around Livestock and Poultry Facilities

  • Prescribed Grazing Systems converted from Cropping Systems

  • Residue and Tillage Management: No-till/Strip-Till/Direct Seed

  • Cover Crops

  • Precision Application of Pesticides

  • Strip Cropping, Conservation Crop Rotation, and Contour Farming

NRCS offers Financial Assistance for implementing many of the above practices to improve Air Quality through the Environmental Quality Incentives Program (EQIP). In addition, special EQIP funding is available in the 24 designated non-attainment counties. Click here for more information on EQIP and how to apply.
