2Q 15A NCAC 02Q or Title 40 of the CFR and are not intended to establish minimum requirements for the purpose of determining the monitoring to be imposed under another Rule in this Subchapter or Subchapter 15A NCAC 2Q 15A NCAC 02Q or Title 40 of the CFR. The purpose of this Rule is to require, as part of the issuance of a permit under 15A NCAC 2Q .0500, 15A NCAC 02Q .0500, improved or new monitoring at those emissions units where monitoring requirements do not exist or are inadequate to meet the requirements of this Rule;
(2)restrict or abrogate the authority of the Division to impose additional or more stringent monitoring, recordkeeping, testing, or reporting requirements on any owner or operator of a source under any provision of this Subchapter or Subchapter 15A NCAC 2Q 15A NCAC 02Q or the General Statutes;
(3)restrict or abrogate the authority of the Division to take any enforcement action for any violation of an applicable requirement; or
(4)restrict the authority of the Administrator of the Environmental Protection Agency or of any person to take action under Section 304 of the federal Clean Air Act as stated under 40 CFR 64.10.

Authority G.S. 143-215.3(a)(3); 143-215.65; 143-215.66; 143-215.107(a)(4).



For the purpose of this Section, the following definitions apply:

(1)"Coating" means a functional, protective, or decorative film applied in a thin layer to a surface.

(2)"Coating applicator" means an apparatus used to apply a surface coating.

(3)"Coating line" means one or more apparatus or operations in a single line wherein a surface coating is applied, dried, or cured and which include a coating applicator and flashoff area and may include an oven or associated control devices.

(4)"Continuous vapor control system" means a vapor control system which treats vapors displaced from tanks during filling on a demand basis without intermediate accumulation.

(5)"Delivered to the applicator" means the condition of coating after dilution by the user just before application to the substrate.

(6)"Flashoff area" means the space between the application area and the oven.

(7)"High solids coating" means a coating which contains a higher percentage of solids and a

lower percentage of volatile organic compounds and water than conventional organic solvent borne coatings.

(8)"Hydrocarbon" means any organic compound of carbon and hydrogen only.

(9)"Incinerator" means a combustion apparatus designed for high temperature operation in which solid, semisolid, liquid, or gaseous combustible wastes are ignited and burned efficiently and from which the solid and gaseous residues contain little or no combustible material.

(10)"Intermittent vapor control system" means a vapor control system which employs an intermediate vapor holder to accumulate vapors displaced from tanks during filling.  The control device treats the accumulated vapors only during automatically controlled cycles.

(11)"Loading rack" means an aggregation or combination of loading equipment arranged so that all loading outlets in the combination can be connected to a tank truck or trailer parked in a specified loading space.

(12)"Low solvent coating" means a coating which contains a substantially lower amount of volatile organic compound than conventional organic solvent borne coatings; it usually falls into one of three major groups of high solids, waterborne, or powder coatings.

(13)"Organic material" means a chemical compound of carbon excluding carbon monoxide, carbon dioxide, carbonic acid, metallic carbides or carbonates, and ammonium carbonate.

(14)"Oven" means a chamber within which heat is used to bake, cure, polymerize, or dry a surface coating.

(15)"Potential emissions" means the quantity of a pollutant which would be emitted at the maximum capacity of a stationary source to emit the pollutant under its physical and operational design.  Any physical or operational limitation on the capacity of the source to emit a pollutant, including air pollution control equipment and restrictions on hours of operation or on the type or amount of material combusted, stored, or processed, shall be treated as part of its design if the limitation or the effect it would have on emissions is described or contained as a condition in the federally enforceable permit.  Secondary emissions do not count in determining potential emissions of a stationary source.  Fugitive emissions count, to the extent quantifiable, in determining the potential emissions only in these cases:

(a)petroleum refineries;

(b)chemical process plants; and
