The following activities are covered under this section:
Air Quality Goal Setting - the activity of establishing standards based on scientific or technical assessment with the aim of mitigating the harmful health and environmental effects of various air pollutants.
Control Strategies - A control strategy is a set of discrete and specific measures identified and implemented to achieve reductions in air pollution. These measures may vary by source type, such as stationary or mobile, as well as by the pollutant that is being targeted. The purpose of these measures is to achieve the air quality standard or goal. Costs and benefits are assessed in the development of the control strategy.
Air Quality Modeling - the mathematical prediction of ambient concentrations of air pollution, based on measured inputs.
Human and Environmental Assessment - conducted as part of an Air Quality Management program to quantify and monetize: 1) the impact of the existing or current state of emissions and air quality; and 2) the incremental impact of a specific policy or program to reduce emissions and improve the current state of air quality.
Legislation: Synonymous with law or statute, legislation is established by a governing authority and in general can be enforced by the courts. Air quality legislation generally contains broad program goals and objectives as well as roles and responsibilities for achieving national air quality protection. In the U.S., national legislation is developed and finalized within the U.S. Congress and signed by the President.
Regulation: Synonymous with rule, regulations are developed by a governing authority and usually provide more specific information for how the broad legislative objectives will be met. In the U.S., national environmental regulations are developed primarily by the Environmental Protection Agency (EPA).
Implementation: The process of developing detailed plans, procedures and mechanisms needed to ensure legislative and regulatory requirements are achieved. In the U.S., though much legislation is passed nationally, individual States are the primary implementers of air quality management programs.
Compliance involves actions and programs designed to ensure the environmental laws of the land are followed. Enforcement is focused on those situations when the law is not followed to ensure a rapid return to compliance with these laws.
Ambient Monitoring is the systematic, long-term assessment of pollutant levels by measuring the quantity and types of certain pollutants in the ambient air.
Emissions Measurement is the process of monitoring particulate and gaseous emissions from a specific source.
Emissions Inventory - a database that lists, by source, the amount of air pollutants discharged into the atmosphere of a community during a given time period.
