Protecting Public Health and the Environment.
DEQ's air quality monitoring program encompasses operation of a monitoring network, laboratory analysis of air samples, and quality assurance activities to ensure data integrity. The program collects real-time measurements of ambient levels of air contaminants at more than 20 sites throughout the state. Integrated sampling methods are used at another 10 sites.
DEQ's monitoring network measures the levels of five of the six ambient air criteria pollutants identified by the federal Clean Air Act. The criteria pollutants are:
Data are used to:
To provide a quantifiable means to measure air quality, EPA's Office of Air Planning and Standards, has established standards for the six criteria pollutants referenced above. For each criteria pollutant, the standard includes a maximum concentration above which adverse effects on human health may occur. These threshold concentrations are called the National Ambient Air Quality Standards (NAAQS).
There are two types of standards: primary and secondary. Primary standards set limits to protect public health, including the health of "sensitive" populations, such as asthmatics, children, and the elderly. Secondary standards set limits to protect public welfare, including protection against decreased visibility, damage to animals, vegetation, and buildings. Idaho has adopted the federal air quality standards in the Rules for the Control of Air Pollution in Idaho (IDAPA 58.01.01.575-587).
Each year DEQ issues an annual report to inform the public of air quality throughout Idaho. The report summarizes regional air quality while presenting air monitoring results for the six criteria air pollutants.
To assure that ambient and metorological data collected by Idaho's air monitoring network meet or exceed required standards, DEQ developed the Idaho Quality Assurance Manual, Ambient Methods, in 1987. The manual prescribes detailed operational procedures for sampling, analyzing, and reporting air pollution and meteorological conditions. The manual is reviewed annually and revised as needed, subject to approval by the U.S. Environmental Protection Agency (EPA). The Idaho Quality Assurance Project Plan is the latest revision to this base document.
Each year DEQ develops a report on whether the monitoring network is achieving its monitoring objectives and identifying needed modifications. The document documents changes made to the monitoring network since the last review and proposed changes for the next year. The plan is submitted to EPA annually by July 1.
