Appendix L to Part 51 - Example Regulations for Prevention of Air
Pollution Emergency Episodes
The example regulations presented herein reflect generally
recognized ways of preventing air pollution from reaching levels
that would cause imminent and substantial endangerment to the
health of persons. States are required under subpart H to have
emergency episodes plans but they are not required to adopt the
regulations presented herein.
1.0 Air pollution emergency. This regulation is designed
to prevent the excessive buildup of air pollutants during air
pollution episodes, thereby preventing the occurrence of an
emergency due to the effects of these pollutants on the health of
persons.
1.1 Episode criteria. Conditions justifying the
proclamation of an air pollution alert, air pollution warning, or
air pollution emergency shall be deemed to exist whenever the
Director determines that the accumulation of air pollutants in any
place is attaining or has attained levels which could, if such
levels are sustained or exceeded, lead to a substantial threat to
the health of persons. In making this determination, the Director
will be guided by the following criteria:
(a) Air Pollution Forecast: An internal watch by the
Department of Air Pollution Control shall be actuated by a National
Weather Service advisory that Atmospheric Stagnation Advisory is in
effect or the equivalent local forecast of stagnant atmospheric
condition.
(b) Alert: The Alert level is that concentration of
pollutants at which first stage control actions is to begin. An
Alert will be declared when any one of the following levels is
reached at any monitoring site:
SO2 - 800 µg/m 3 (0.3 p.p.m.), 24-hour average. PM10 - 350 µg/m 3,
24-hour average. CO - 17 mg/m 3 (15 p.p.m.), 8-hour average. Ozone
(O2) = 400 µg/m 3 (0.2 ppm)-hour average. NO2-1130 µg/m 3 (0.6
p.p.m.), 1-hour average, 282 µg/m 3 (0.15 p.p.m.), 24-hour average.
In addition to the levels listed for the above pollutants,
meterological conditions are such that pollutant concentrations can
be expected to remain at the above levels for twelve (12) or more
hours or increase, or in the case of ozone, the situation is likely
to reoccur within the next 24-hours unless control actions are
taken.
(c) Warning: The warning level indicates that air quality
is continuing to degrade and that additional control actions are
necessary. A warning will be declared when any one of the following
levels is reached at any monitoring site:
SO2 - 1,600 µg/m 3 (0.6 p.p.m.), 24-hour average. PM10 - 420 µg/m
3, 24-hour average. CO - 34 mg/m 3 (30 p.p.m.), 8-hour average.
Ozone (O3) - 800 µg/m 3 (0.4 p.p.m.), 1-hour average. NO2 - 2,260
µg/m 3 (1.2 ppm) - 1-hour average; 565 µg/m 3 (0.3 ppm), 24-hour
average.
In addition to the levels listed for the above pollutants,
meterological conditions are such that pollutant concentrations can
be expected to remain at the above levels for twelve (12) or more
hours or increase, or in the case of ozone, the situation is likely
to reoccur within the next 24-hours unless control actions are
taken.
(d) Emergency: The emergency level indicates that air
quality is continuing to degrade toward a level of significant harm
to the health of persons and that the most stringent control
actions are necessary. An emergency will be declared when any one
of the following levels is reached at any monitoring site:
SO2 - 2,100 µg/m 3 (0.8 p.p.m.), 24-hour average. PM10 - 500 µg/m
3, 24-hour average. CO - 46 mg/m 3 (40 p.p.m.), 8-hour average.
Ozone (O3) - 1,000 µg/m 3 (0.5 p.p.m.), 1-hour average. NO2-3,000
µg/m 3 (1.6 ppm), 1-hour average; 750 µg/m 3 (0.4 ppm), 24-hour
average.
In addition to the levels listed for the above pollutants,
meterological conditions are such that pollutant concentrations can
be expected to remain at the above levels for twelve (12) or more
hours or increase, or in the case of ozone, the situation is likely
to reoccur within the next 24-hours unless control actions are
taken.
(e) Termination: Once declared, any status reached by
application of these criteria will remain in effect until the
criteria for that level are no longer met. At such time, the next
lower status will be assumed.
1.2 Emission reduction plans. (a) Air Pollution Alert -
When the Director declares an Air Pollution Alert, any person
responsible for the operation of a source of air pollutants as set
forth in Table I shall take all Air Pollution Alert actions as
required for such source of air pollutants and shall put into
effect the preplanned abatement strategy for an Air Pollution
Alert.
(b) Air Pollution Warning - When the Director declares an Air
Pollution Warning, any person responsible for the operation of a
source of air pollutants as set forth in Table II shall take all
Air Pollution Warning actions as required for such source of air
pollutants and shall put into effect the preplanned abatement
strategy for an Air Pollution Warning.
(c) Air Pollution Emergency - When the Director declares an Air
Pollution Emergency, any person responsible for the operation of a
source of air pollutants as described in Table III shall take all
Air Pollution Emergency actions as required for such source of air
pollutants and shall put into effect the preplanned abatement
strategy for an Air Pollution Emergency.
(d) When the Director determines that a specified criteria level
has been reached at one or more monitoring sites solely because of
emissions from a limited number of sources, he shall notify such
source(s) that the preplanned abatement strategies of Tables I, II,
and III or the standby plans are required, insofar as it applies to
such source(s), and shall be put into effect until the criteria of
the specified level are no longer met.
1.3 Preplanned abatement strategies, (a) Any person
responsible for the operation of a source of air pollutants as set
forth in Tables I-III shall prepare standby plans for reducing the
emission of air pollutants during periods of an Air Pollution
Alert, Air Pollution Warning, and Air Pollution Emergency. Standby
plans shall be designed to reduce or eliminate emissions of air
pollutants in accordance with the objectives set forth in Tables
I-III which are made a part of this section.
(b) Any person responsible for the operation of a source of air
pollutants not set forth under section 1.3(a) shall, when requested
by the Director in writing, prepare standby plans for reducing the
emission of air pollutants during periods of an Air Pollution
Alert, Air Pollution Warning, and Air Pollution Emergency. Standby
plans shall be designed to reduce or eliminate emissions of air
pollutants in accordance with the objectives set forth in Tables
I-III.
(c) Standby plans as required under section 1.3(a) and (b) shall
be in writing and identify the sources of air pollutants, the
approximate amount of reduction of pollutants and a brief
description of the manner in which the reduction will be achieved
during an Air Pollution Alert, Air Pollution Warning, and Air
Pollution Emergency.
(d) During a condition of Air Pollution Alert, Air Pollution
Warning, and Air Pollution Emergency, standby plans as required by
this section shall be made available on the premises to any person
authorized to enforce the provisions of applicable rules and
regulations.
(e) Standby plans as required by this section shall be submitted
to the Director upon request within thirty (30) days of the receipt
of such request; such standby plans shall be subject to review and
approval by the Director. If, in the opinion of the Director, a
standby plan does not effectively carry out the objectives as set
forth in Table I-III, the Director may disapprove it, state his
reason for disapproval and order the preparation of an amended
standby plan within the time period specified in the order.
