ARIZONA ADMINISTRATIVE CODE 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, and49-541, the terms ofthis Chapter, unless otherwise specified, shall have the following meanings: 1. “Act’ means the Clean AirAct 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 ofa particular date shall equal the average rate, in tons per year, atwhich the unit actually emitted thepollutant during atwo-yearperiod which precedes the particulardate and which is representative ofnormal source operation. The Directormay allow the use ofa differenttime period upon ademonstration that it is more representative of normal source operation. Actual emissions shall becalculatedusingtheunit’s actual operating hours, production rates, and types ofmaterials processed, stored or combusted during the selected time period. b. Ifthere is inadequate information to determine actual historical emissions, the Directormay presume that source-specific allowable emissions for the unit are equivalent to the actual emissions ofthe unit.
c. For any emissions unit which has not begun normal operations on the particular date, actual emissions shall equal the potential to emit ofthe unit on that date. 3. “Administrator” means the Administrator ofthe 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 ofthe Act. 6. “Affected state” means any state whose air quality may be affected by a source applying for apermit, permit revision or permit renewal, and that is contiguous to Arizona; or that is within 50 miles ofthe permitted source. 7. “Afterburner” means an incinerator installed in the secondary combustion chamber or stack for the purpose ofincinerating 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 ofonly wood waste and slash materials in an earthen

Ifthe 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) ofthis Section is being violated, the SIP shall be revised to correct the inadequacy or the violation. The SIP shall be revised within 60 days ofsuch a finding by the Director orwithin 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 ofthe 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 peryearofthe ambient airquality 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 ofambient air quality standards. C. The provisions ofsubsection (A) ofthis Section shall not apply to any ofthe following: 1. The annual and quarterly standards. 2. The 

### standards for ozone prescribed in R18-2-203. 3. The primary and secondary 24-hour PM10 standards prescribed in Ri8-2-201.
R18-2-220. Air pollution emergency episodes
A. Procedures shall be implemented by the Director in order to prevent the occurrence ofambient air pollutant concentrations which would cause significant harm to the health ofpersons, as specified in subsection (BX4) of this Section. The procedures and actions required for each stage are described in the Department’s ‘Procedures forPrevention ofEmergency Episodes,” amended as ofOctober 18, 1988 (and no future editions), which is incorporated herein by reference and on file with the Office ofthe Secretary ofState. B. The following stages are identifiedby airquality criteriain orderto provide forsequential emissions reductions, public notification, and increased Department monitoring and forecast responsibilities. The declaration ofany stage, andthe areaofthe state affected, shall bebased on air quality measurements andmeteorological analysis and forecast. 1. A Stage I air pollution alert shall be declared when any ofthe alert level concentrations listed in paragraph (4) ofthis subsectionareexceededatanymonitoring site andwhenmeteorological conditions indicate that there will be a continuance or recurrence of alert level concentrations for the same pollutant during the subsequent 24-hourperiod. 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 implementedbutno warning shallbe declared, unless air qualityhas deterioratedto the extent described in paragraph (2) ofthis subsection. 2. A Stage II airpollution warning shall be declared when any ofthe warning level concentrations listed in paragraph (4) of this subsection are exceeded at any monitoring site and when meteorological conditions indicatethattherewillbe acontinuance orrecurrenceofconcentrations ofthe samepollutant exceeding the warning level during the subsequent 24-hour period. If, 48 hours after a warning has been initially declared, airpollution 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 ofthe emergency level concentrations listed in paragraph (4) ofthis subsection are exceeded at any monitoring site and when meteorological conditions indicatethattherewillbe acontinuanceorrecurrenceofconcentrations ofthe samepollutant exceeding the emergency level during the subsequent 24-hour period. 4.
