 Welcome to the North Carolina Division of Air Quality

(a) The rules in this Section do not apply except as specifically set out in this Rule. (b) This Section applies to sources that emit greater than or equal to 15 pounds of volatile organic compounds per day unless specified otherwise in this Section. (c) Rules .0925, .0926, .0927, .0928, .0931, .0932, .0933, and .0958 of this Section apply regardless of the levelofemissions of volatile organic compounds unless provisions specified in Paragraph (d)(1) of this Rule are applied. (d) This Section does not apply to: (1) sources that emit less than 800 pounds of volatile organic compounds per calendar monthandthatare:


(B) (C) (D)

bench-scale, on-site equipment used exclusively for chemical or physical analysis forquality control purposes, staff instruction, water or wastewater analyses, or non-production environmental compliance assessments; bench-scale experimentation, chemical or physical analyses, training or instruction fromnotfor-profit, non-production educational laboratories; bench-scale experimentation, chemical or physical analyses, training or instruction from hospitals or health laboratories pursuant to the determination or diagnoses of illness; or research and development laboratory activities, provided the activity producesnocommercial product or feedstock material; or


emissions of volatile organic compounds during startup or shutdown operations fromsourceswhich use incineration or other types of combustion to control emissions of volatile organic compounds whenever the off-gas contains an explosive mixture during the startup or shutdown operation if the exemption is approved by the Director as meeting the requirements of this Subparagraph.

(e) The following rules of this Section apply to facilities located statewide:

(1) (2) (3) (4) (5) (6) (7) (8) (9) .0925, PetroleumLiquid Storage in Fixed Roof Tanks, for fixed roof tanks at gasoline bulk plants and gasoline bulk terminals; .0926, Bulk Gasoline Plants; .0927, Bulk Gasoline Terminals; .0928, Gasoline Service Stations Stage I; .0932, Gasoline Truck Tanks and Vapor Collection Systems; .0933, PetroleumLiquid Storage in External Floating Roof Tanks, for external floating rooftanksatbulk gasoline plants and bulk gasoline terminals; .0948, VOC Emissions fromTransfer Operations; .0949, Storage of Miscellaneous Volatile Organic Compounds; and .0958, Work Practices for Sources of Volatile Organic Compounds.

(f) Except as provided in Paragraph (e) of this Rule, the rules in this Section apply to facilities subject toSection182(b)(2) of the Clean Air Act with potential to emit 100 or more tons per year of VOC and to facilities with potential to emit less than 100 tons per year of volatile organic compounds in categories for which the United States EnvironmentalProtection Agency has issued Control Technique Guidelines that are located in the following moderate nonattainment areasforthe 1997 8-hour ozone standard as designated in 40 CFR 81.334:

(1) (2) (3) (4) (5) (6) (7) Cabarrus County; Gaston County; Lincoln County; Mecklenburg County; Rowan County; Union County; and Davidson Township and Coddle Creek Township in Iredell County.

These facilities are subject to reasonably available control technology requirements under this Section and shallcomply with these requirements in accordance with Rule .0909 of this Section through use of Rule .0951 of this Section. (g) If any county or part of a county to which this Section applies is later designated in 40 CFR 81.334 as attainmentand becomes a maintenance area for the 1997 8-hour ozone standard, all sources in that county or part of county subjectto Paragraph (f) of this Rule that achieved compliance in accordance with Rule .0909 of this Section shallcontinuetocomply with this Section. Facilities with potential to emit less than 100 tons of volatile organic compounds per yearforwhichthe compliance date in Rule .0909 of this Section has not passed before redesignation of the area to attainment for the1997 ozone standard shall comply in accordance with Paragraph (h) of this Rule.


(h) If a violation of the 1997 ambient air quality standard for ozone occurs when the areas listed in Paragraph(f)become ozone maintenance area, no later than 10 days after the violation occurs, the Director shall initiate technical analysisto determine the control measures needed to attain and maintain the 1997 8-hour ambient air quality standard forozone.By the following May 1, the Director shall implement the specific stationary source control measures contained in this Section that are required as part of the control strategy necessary to bring the area into compliance and to maintain compliance with the 1997 8-hour ambient air quality standard for ozone. The Director shall implement the rules in this Section identified as being necessary by the analysis by notice in the North Carolina Register. The notice shall identify the rules that are to be implemented and shall identify whether the Rules implemented are to apply in the areas listedin Paragraph (f) of this Rule. At least one week before the scheduled publication date of the North Carolina Register containing the Director's notice implementing rules in this Section, the Director shall send written notification to all permitted facilities within the counties in which the Rules of this Section are being implemented notifying themthatthey are or may be subject to the requirements defined in Rule .0909 of this Section. For Mecklenburg County, "Director" means, for the purpose of notifying permitted facilities in MecklenburgCounty,the Director of the Mecklenburg County local air pollution control program. (i) Sources whose emissions of volatile organic compounds are not subject to limitation under this Section may stillbe subject to emission limits on volatile organic compounds in Rules .0524, .1110, or .1111 of this Subchapter.
