How many new source performance standards are there?
New Source Performance Standards (NSPS) EPA has issued New Source Performance Standards for over 70 specific source categories. These source-based standards apply to new and modified facilities.
What is considered a hap?
Hazardous air pollutants (HAPs) are those pollutants that are known or suspected to cause cancer or other serious health effects, such as reproductive effects or birth defects, or adverse environmental effects.
What are the basic requirements of the Prevention of Significant Deterioration PSD program?
What Does PSD Require?
- installation of the “Best Available Control Technology” (BACT);
- an air quality analysis;
- an additional impacts analysis; and.
- public involvement.
What are MACT standards?
MACT standards are performance criteria designed to significantly reduce air toxics emissions. The audit objectives were to identify efficiencies that could be implemented to accelerate the MACT standards development process, and to evaluate the Agency’s method of determining the MACT floor for emission standards.
How are HAPs regulated?
The Clean Air Act requires the U.S. EPA to regulate emissions of air pollutants that are hazardous to human health or the environment, called hazardous air pollutants (HAPs). The regulations are known as National Emission Standards for Hazardous Air Pollutants (NESHAP).
What is MACT environmental?
What are MACTs? The United States Clean Air Act legally mandated that the EPA regulate the emission of hazardous air pollutants (HAPs) by industrial sources. To accomplish this mandate, the EPA developed MACT – Maximum Achievable Control Technology – standards.
What are PSD areas?
Prevention of Significant Deterioration (PSD) applies to new major sources or major modifications at existing sources for pollutants where the area the source is located is in attainment or unclassifiable with the National Ambient Air Quality Standards (NAAQS).
What are PSD increments?
PSD increment is the amount of pollution an area is allowed to increase. PSD increments prevent the air quality in clean areas from deteriorating to the level set by the NAAQS.
What is considered major under PSD?
Answer: A major source is any facility or plant that is on EPA’s list of source categories and emits or has the potential to emit at least 100 tons per year (tpy) or more of any single criteria pollutant.
