In this chapter, the following definitions apply:

Air quality control zone” means the area of the Borough currently contained in the EPA designated nonattainment area, which uses the nonattainment area southern, western and eastern boundaries as modified by their respective intersection with the following northern boundary described as: beginning at the intersection of Isberg Road with Chena Ridge Road on the western boundary of the EPA designated nonattainment area, then following Chena Ridge Road back to Chena Pump Road and continuing north on the Parks Highway to Sheep Creek Road, then Sheep Creek Road to Miller Hill Road, then north on Miller Hill Road, then east on Yankovich, then north from Yankovich Road along the east boundary of the Large Animal Research Station to a point just north of its intersection with Nottingham Drive and follows the ridge crest across Nottingham Estates to approximately the point where Swallow Drive intersects Dalton Trail to north on Dalton Trail to the crest of the Farmer’s Loop Ridge, then follow the geographic crest of Farmer’s Loop Ridge to its intersection with the New Steese Highway, then southeast on Bennett Road, and along Steele Creek Road to the intersection of Chena Hot Springs Road, and Chena Hot Springs Road to the eastern boundary of the EPA designated nonattainment area.

Air quality index” (AQI) is an index for reporting daily air quality, which indicates how polluted the air currently is or how polluted it is forecast to become. The higher the AQI value, the greater the level of air pollution and the greater the health concern. AQI is divided into six categories with correspondingly higher levels of health concern as outlined in the table below:

AQI
(Air Quality Index)

AQI Category

Cautionary Statement

Health Statement

0 – 50

Good

None

None

51 – 100

Moderate

Unusually sensitive people should consider reducing prolonged or heavy exertion.

None

101 – 150

Unhealthy for Sensitive Groups

People with respiratory or heart disease, the elderly, and children should limit prolonged exertion.

Increasing likelihood of respiratory symptoms in sensitive individuals, aggravation of heart or lung disease and premature mortality in persons with cardiopulmonary disease and the elderly.

151 – 200

Unhealthy

People with respiratory or heart disease, the elderly, and children should avoid prolonged exertion; everyone else should limit prolonged exertion.

Increased aggravation of heart or lung disease and premature mortality in persons with cardiopulmonary disease and the elderly; increased respiratory effects in general population.

201 – 300

Very Unhealthy

People with respiratory or heart disease, the elderly, and children should avoid outdoor activity; everyone else should avoid prolonged exertion.

Significant aggravation of heart or lung disease and premature mortality in persons with cardiopulmonary disease and the elderly; significant increase in respiratory effects in the general population.

301 – 500

Hazardous

Everyone should avoid any outdoor exertion; people with respiratory or heart disease, the elderly and children should remain indoors.

Significant aggravation of heart or lung disease and premature mortality in persons with cardiopulmonary disease and the elderly; significant increase in respiratory effects in the general population.
