TITLE 18. ENVIRONMENTAL QUALITY

CHAPTER 2. DEPARTMENT OF ENVIRONMENTAL QUALITY - AIR POLLUTION CONTROL

ARTICLE 1. GENERAL

R18-2-1O1. Definitions

In addition to the defmitions prescribed in A.R.S. § 49-101, 49-401.01, 49-421, 49-521, and 49-541, the terms of this

Chapter, unless otherwise specified, shall have the following meanings:

1. “Act’ means the Clean Air Act of 1963 (P.L. 88-206; 42 United States Code § 7401 through 7671q)

as amended by the Clean Air Act Amendments of 1990 (P.L. 101-549).

2. “Actual emissions” means the actual rate of emissions of a pollutant from an emissions unit, as

determined in accordance with subparagraphs (a) through Cc).

a. In general, actual emissions as of a particular date shall equal the average rate, in tons per

year, at which the unit actually emitted the pollutant during a two-year period which precedes

the particular date and which is representative of normal source operation. The Director may

allow the use of a different time period upon a demonstration that it is more representative of

normal source operation. Actual emissions shall be calculated using the unit’s actual operating

hours, production rates, and types of materials processed, stored or combusted during the

selected time period.

b. If there is inadequate information to determine actual historical emissions, the Director may

presume that source-specific allowable emissions for the unit are equivalent to the actual

emissions of the unit.

c. For any emissions unit which has not begun normal operations on the particular date, actual

emissions shall equal the potential to emit of the unit on that date.

3. “Administrator” means the Administrator of the United States Environmental Protection Agency.

4. “Affected facility” means, with reference to a stationary source, any apparatus to which a standard is

applicable.

5. “Affected source” means a source that includes one or more units which are subject to emission

reduction requirements or limitations under Title IV of the Act.

6. “Affected state” means any state whose air quality may be affected by a source applying for a permit,

permit revision or permit renewal, and that is contiguous to Arizona; or that is within 50 miles of the

permitted source.

7. “Afterburner” means an incinerator installed in the secondary combustion chamber or stack for the

purpose of incinerating smoke, fumes, gases, unburned carbon, and other combustible material not

consumed during primary combustion.

8. “Air curtain destructor” means an incineration device designed and used to secure, by means of a

fan-generated air curtain, controlled combustion of only wood waste and slash materials in an earthen

G. If the Director or the Administrator determines that the SIP is substantially inadequate to prevent significant

deterioration or that an applicable maximum allowable increase as specified in subsection (A) of this Section

is being violated, the SIP shall be revised to correct the inadequacy or the violation. The SIP shall be revised

within 60 days of such a finding by the Director or within 60 days following notification by the Administrator,

or by such later date as prescribed by the Administrator after consultation with the Director.

H. The Director shall review the adequacy of the SIP on a periodic basis and within 60 days of such time as

information becomes available that an applicable maximum allowable increase is being violated.

R18-2-219. Violations

A. One exceedance per year ofthe ambient air quality standards prescribed in this Article shall be allowed for each

pollutant at each monitoring site.

B. Each additional exceedance at each site shall constitute a separate violation of ambient air quality standards.

C. The provisions of subsection (A) of this Section shall not apply to any of the following:

1. The annual and quarterly standards.

2. The standards for ozone prescribed in R18-2-203.

3. The primary and secondary 24-hour PM1 0 standards prescribed in Ri 8-2-201.

R18-2-220. Air pollution emergency episodes

A. Procedures shall be implemented by the Director in order to prevent the occurrence of ambient air pollutant

concentrations which would cause significant harm to the health of persons, as specified in subsection (BX4)

of this Section. The procedures and actions required for each stage are described in the Department’s

‘Procedures for Prevention of Emergency Episodes,” amended as of October 18, 1988 (and no future editions),

which is incorporated herein by reference and on file with the Office of the Secretary of State.

B. The following stages are identified by air quality criteria in order to provide for sequential emissions reductions,

public notification, and increased Department monitoring and forecast responsibilities. The declaration of any

stage, and the area of the state affected, shall be based on air quality measurements and meteorological analysis

and forecast.

1. A Stage I air pollution alert shall be declared when any of the alert level concentrations listed in

paragraph (4) ofthis subsection are exceeded at any monitoring site and when meteorological conditions

indicate that there will be a continuance or recurrence of alert level concentrations for the same

pollutant during the subsequent 24-hour period. If, 48 hours after an alert has been initially declared,

air pollution concentrations and meteorological conditions do not improve, the warning stage control

actions shall be implemented but no warning shall be declared, unless air quality has deteriorated to the

extent described in paragraph (2) of this subsection.

2. A Stage II air pollution warning shall be declared when any of the warning level concentrations listed

in paragraph (4) of this subsection are exceeded at any monitoring site and when meteorological

conditions indicate that there will be a continuance or recurrence of concentrations ofthe same pollutant

exceeding the warning level during the subsequent 24-hour period. If, 48 hours after a warning has

been initially declared, air pollution concentrations and meteorological conditions do not improve, the

emergency stage shall be declared and its control actions implemented.

3. A Stage III air pollution emergency shall be declared when any of the emergency level concentrations

listed in paragraph (4) of this subsection are exceeded at any monitoring site and when meteorological

conditions indicate that there will be a continuance or recurrence of concentrations ofthe same pollutant

exceeding the emergency level during the subsequent 24-hour period.
