Section 244.102 Responsibility of the Agency

The Director of the Illinois Environmental Protection Agency (Director) or his

designated respresentative has sole authority for the declaration of episode stages under

these rules. The Illinois Environmental Protection Agency (Agency) has primary

responsibility for the conduct of air pollution episode operations including but not limited

to air contaminant monitoring, source surveillance and enforcement activities during air

pollution eqisodes which affect any portion of the State of Illinois. The Agency shall

notify any local agency assigned a significant episode control role in the Illinois Air

Pollution Implementation Plan prior to the initiation, alteration or termination of any

episode stage or control strategy in the jurisdictional area of any such local agency.

Section 244.103 Determination of Required Actions

To the maximum degree practicable, emission control actions taken pursuant to these

rules shall be consistent with the extent of any air pollution alert or emergency.

a) When the existence of any episode stage is caused by one or more specific

emission sources, the Agency shall require emission control action steps

applicable only to such source or sources to be taken.

b) When the existence of any episode stage is caused by one or more specific

air contaminants, action shall be taken to reduce the concentration of such

contaminant or contaminants.

c) When motor vehicle emission control actions are required, the Agency

shall promptly declare the applicable episode stage and phase actions so as

to allow reasonable notice and preparation for effective vehicle control

Section 244.104 Determination of Atmospheric Conditions

When determining expected atmospheric conditions, the Agency shall consider all

available meteorological information, including but not limited to official National

Weather Service observations, analyses, forecasts and advisories, as well as

meteorological data and reports from other sources. Atmospheric conditions shall

include but not be limited to stagnation areas, weather fronts, pressure systems,

inversions, precipitation and wind patterns and variations in solar insolation, temperature

and atmospheric stability.

Section 244.105 Determination of Expected Contaminant Emissions

When determining expected contaminant emissions, the Agency shall consider all

available emission information including but not limited to emission inventories for

stationary sources, pertinent emissions summaries, motor vehicle traffic patterns, and

known or estimated seasonal, daily or hourly variations in emission rates or traffic

Section 244.106 Monitoring

a) Monitoring stations used to determine advisory, alert or emergency levels

shall be located according to Federal guidelines for establishment of air

quality surveillance networks and shall use measurement methods or

equivalent methods as officially authorized by the United States

Environmental Protection Agency (USEPA).

b) Whenever any monitoring station registers air contaminant concentrations

in excess of advisory or alert levels, proper operation of the sampling

equipment at such stations shall be verified by the Agency or any agency

cooperating with the Agency before the concentrations are used to declare

any advisory, alert or emergency stage.

(Source: Amended at 16 Ill. Reg. 8191, effective May 15, 1992)

Section 244.107 Determination of Areas Affected

a) An advisory shall be declared for the entire Illinois portion of any Air

Quality Control Region if any part of such region meets the advisory

criteria. When atmospheric conditions and contaminant emissions in a

region are such as to cause the advisory criteria to be met in another

region, an advisory shall be declared for any Illinois portion of both

b) An alert or emergency shall be declared for only those portions of an

advisory area which meet the applicable criteria of Subpart D of this Part

or cause such criteria to be met elsewhere in Illinois or in another state.

When such criteria have been met, sectors of the advisory area requiring

alert or emergency actions shall be defined depending upon expected

atmospheric conditions, contaminant emissions and dispersion analyses.

Alerts or emergencies shall then be declared for one or more of these

(Source: Amended at 16 Ill. Reg. 8191, effective May 15, 1992)

Section 244.108 Failure to Comply with Episode Requirements

Failure to comply with an approved episode action plan, required actions listed in

Appendix D or the reasonable orders of the Director or his designated representative

during any alert or emergency shall expose any person to the penalty provisions of the

Environmental Protection Act (Ill. Rev. Stat. 1981, ch. 111 1/2, pars. 1001 et seq.)

(Act). In all cases, the reasonable orders of the Director or his designated representative

shall take precedence over episode action plans or required actions listed in Appendix D

provided, however, that such orders shall not exceed that which is authorized by this Part

Section 244.109 Sealing of Offenders
