Current through June 15, 2024
Section 22a-174-6 - Air pollution emergency episode procedures
(a) When air pollutant concentrations monitored by the Department indicate that short term high pollutant levels may be expected which are likely to have an adverse impact on human health, the Commissioner shall prepare for the declaration of an appropriate air pollution emergency episode.
(b)Industrial Emergency episode criteria. In determining that any stage of an air pollution industrial emergency episode exists, the Commissioner shall be guided by the following criteria:
(b)
(1) First Stage: Industrial Air Pollution Alert. An air pollution industrial alert shall be declared whenever the concentration of one or more of the pollutants listed below reaches the described level at any monitoring site operated by the Department:

A SO2 concentration of 800 µg/m3 (0.3 ppm), 24-hour average;

A PM10 concentration of 350 µg/m3, averaged over 24-hours, measured in accordance with the provisions of Appendix C of Title 40 Code of Federal Regulations part 58 revised as of July 1, 1989; or

A NO2 concentration of 1130 µg/m3 (0.6 ppm), 1-hour average; 282 µg/m3 (0.15 ppm), 24-hour average; and meteorological conditions are such that the pollutant concentrations can be expected, unless control actions are taken, to remain at the above levels or increase over a period of twelve (12) or more hours.

(b)
(2) Second Stage: Industrial Air Pollution Warning. An industrial air pollution warning shall be declared whenever one of the following levels is reached at any monitoring site operated by the Department:

A SO2 concentration of 1,600 µg/m3 (0.6 ppm), 24-hour average;

(d)
(1) Preplanned abatement strategies. Any person responsible for the operation of a source of air pollutants that emits, or has the capacity to emit, 100 tons or more of pollutants a year as determined before the application of control equipment, shall prepare a standby plan for reducing the emission of air pollutants during each of the three stages of an industrial air pollution emergency episode, i.e., Industrial Alert; Industrial Warning; Industrial Emergency. Standby plans shall be designed to reduce or eliminate emission of air pollutants in accordance with the requirements set forth in Tables I-III.
(d)
(2) Any person responsible for the operation of a source of air pollutants not set forth under subdivision (d) (1) shall, when requested by the Commissioner, prepare standby plans for reducing the emissions of air pollutants during each of the four stages of an industrial air pollution emergency episode. Such standby plans shall be designed to reduce or eliminate emissions of air pollutants in accordance with the requirements set forth in Tables I-III.
(d)
(3) All standby plans shall be in writing, identify the source of air pollutants, contain a commitment as to the amount of reduction to be achieved, and set forth in sufficient detail for the Commissioner to evaluate the manner in which the reduction will be accomplished.
(d)
(4) During any Industrial Air Pollution Emergency Episode, standby plans shall be made available on the premises to persons authorized to enforce these regulations.
(d)
(5) The standby plans required by subdivision (d) (1) shall be submitted to the Commissioner by August 1, 1972. Standby plans requested by the Commissioner under subdivision (d) (2) shall be submitted within 90 days of the date of receipt of the request. When in the judgment of the Commissioner a standby plan is not adequate to carry out the objectives set forth in Tables I-III, he may reject the plan and require that it be resubmitted in an acceptable form within 30 days from the date of rejection.
(e)Declaration of an industrial air pollution emergency episode in aid of sister state. Notwithstanding that the concentration of pollutants in the air over the State of Connecticut does not meet the criteria set forth in subdivisions (b) (1) to (b) (3) for any stage of an industrial air pollution emergency episode, the Commissioner may nevertheless declare such emergency episode to be in effect at the stage level he deems appropriate when it becomes necessary to reduce the level of air pollutants in Connecticut to avoid intensifying deteriorated air conditions in one or more areas outside the state that are endangering the health and welfare of residents in those areas.
(f)Emissions from a limited number of sources. Whenever the Commissioner determines that a specified emergency criteria level set forth in subdivisions (b) (1) to (b) (3) has been reached in a limited area, he may restrict the response to such emergency in the manner he deems appropriate, including notification to those sources contributing to the emergency levels that the abatement actions of Tables I, II, or III, as the case may be, are required and shall be put into effect until the pollutant levels are reduced below the criteria levels.
(g)Automotive emergency episode criteria. In determining any stage of an automotive air pollution emergency episode to exist, the Commissioner shall be guided by the following criteria:
(g)
(1) First Stage: Automotive Air Pollution Alert. An automotive air pollution alert shall be declared whenever the concentration of one or more of the pollutants listed below reaches the described level at any monitoring site operated by the Department of Environmental Protection: CO: 17 µg/m3 (15 ppm), 8-hour average; Oxidant (O3): 400 µg/m3(0.2 ppm), 1-hour average; and meteorological conditions are such that the pollutant concentrations can be expected, unless control actions are taken, to recur the next calendar day.
(g)
(2) Second Stage: Automotive Air Pollution Warning. An automotive air pollution warning shall be declared whenever evidence shows that air quality is continuing to degrade from the automotive air pollution advisory and alert one of the following levels is reached at any monitoring site operated by the Department of Environmental Protection: CO: 34 µg/m3 (30 ppm), 8-hour average;

Oxidant (O3) 800 µg/m3 (0.4 ppm), 1-hour average; and meteorological conditions are such that pollutant concentrations can be expected, unless control actions are taken, to recur the next calendar day.

(g)
(3) Third Stage: Automotive Air Pollution Emergency. An automotive air pollution emergency shall be declared whenever evidence shows that air quality has degraded to a level deemed unacceptable by the commissioner under any circumstances and requiring the most stringent control actions. An automotive air pollution emergency will automatically be declared when any one of the following levels is reached at any monitoring site operated by the Department of Environmental Protection: CO: 46 µg/m3 (40 ppm), 8-hour average;

Oxidant (O3): 1,000 µg/m3 (0.5 ppm), 1-hour average; and meteorological conditions are such that this condition can be expected to recur the next calendar day.

(g)
(4) Termination. Once any stage of an automotive air pollution emergency episode has been declared, it shall remain in effect until the Commissioner announces its termination.
(h)Plans of action at each stage of emergency.
(h)
(1) First Stage: Automotive Air Pollution Alert. Whenever the Commissioner declares an automotive air pollution alert, all unessential operation of motor vehicles shall be terminated.
(h)
(2) Second Stage: Automotive Air Pollution Warning. Whenever the Commissioner declares an automotive air pollution warning, persons operating motor vehicles must reduce operations by the use of car pools and increased use of public transportation and elimination of unnecessary operation.
(h)
(3) Third Stage: Automotive Air Pollution Emergency. Whenever the Commissioner declares an automotive air pollution emergency, all private non-commercial motor vehicle operations shall cease except where absolutely essential for necessities of life including medical treatment, and commercial vehicle operations shall be reduced to the absolute minimum necessary to transport necessities and provide for public safety and welfare.
