Major Source and Area Source Programs

• National Emission Standards for Hazardous Air Pollutants
  Standards that involve the use of Maximum Achievable Control Technology to reduce major point source and area source emissions of toxic air pollutants.

• New Source Performance Standards
  Regulations that affect new sources of toxic pollutants (and some existing sources) involving medical waste incinerators, landfills, municipal waste combustors, steam generating boilers.

• Small Business Assistance Program
  This program assists small businesses with regulatory compliance, provides information about cost saving pollution prevention practices, and ensures that small business are considered when new regulations are developed.

• Energy and Technology Development
  By identifying opportunities for businesses to conserve energy, resources, and minimize waste, not only increases productivity and profits, but reduces emissions of undesired pollution.

• Design for the Environment
  Program works with several industry sectors to identify cost-effective alternatives to existing products and processes that reduce risks to workers and the environment while maintaining or improving performance and product quality.

Mobile Source Programs

• Vehicle Emission Testing
  An inspection program to ensure a vehicle's pollution control system is functioning properly.

• Reformulated Gas
  Regulations that require gasoline to be "reformulated" with oxygenates so as to result in significant reductions in vehicle emissions of ozone-forming and toxic air pollutants.

• Stage II Vapory Recovery Systems
  A system designed to capture gasoline vapors that would otherwise escape into the atmosphere as vehicles are refueled.

• Tier 2 and Low Sulfur Gasoline
  New tailpipe emissions standards for all passenger vehicles, including sport utility vehicles (SUVs), minivans, vans and pick-up trucks, as well as, new standards to reduce the sulfur content of gasoline by up to 90 percent, which will ensure the effectiveness of low emission-control technologies in vehicles and reduce harmful air pollution. 

• Diesel Emissions and Fuel​
  Rules for the first phase of a two-part strategy to significantly reduce harmful diesel emissions from heavy-duty trucks and buses, as well as, new qua​lity requirements for diesel fuel to enable the use of a new generation of emission control technologies for diesel engines.
