(a) For the purpose of this Rule, the following definitions shall
apply:
(1) "End sealing compound" means a synthetic rubber compound that is
coated onto can ends and functions as a gasket when the end is
assembled on the can.
(2) "Exterior base coating" means a coating applied to the exterior of
a can to provide exterior protection to the metal and to provide
background for the lithographic or printing operation.
(3) "Interior base coating" means a coating applied by roller coater
or spray to the interior of a can to provide a protective lining
between the can metal and product.
(4) "Interior body spray" means a coating sprayed on the interior of
the can body to provide a protective film between the product and the
can.
(5) "Overvarnish" means a coating applied directly over ink to reduce
the coefficient of friction, to provide gloss, and to protect the
finish against abrasion and corrosion.
(6) "Three-piece can side-seam spray" means a coating sprayed on the
exterior and interior of a welded, cemented, or soldered seam to
protect the exposed metal.
(7) "Two-piece can exterior end coating" means a coating applied by
roller coating or spraying to the exterior end of a can to provide
protection to the metal.
(b) This Rule applies to volatile organic compound emissions from
coating applicators and ovens of sheet, can, or end coating lines
involved in sheet exterior and interior basecoat and overvarnish;
two-piece can interior body spray; two-piece spray or roll coat can
exterior; and three-piece can side-seam spray and end sealing compound
operations.
(c) Unless the exception in Paragraph (d) of this Rule applies,
emissions of volatile organic compounds from any can coating line
subject to this Rule shall not exceed:
(1) 4.5 pounds of volatile organic compounds per gallon of solids
delivered to the coating applicator from sheet exterior and interior
basecoat and overvarnish or two-piece can exterior basecoat and
overvarnish operations;
(2) 9.8 pounds of volatile organic compounds per gallon of solids
delivered to the coating applicator from two and three-piece can
interior body spray and two-piece spray or roll coat can exterior end
operations;
(3) 21.8 pounds of volatile organic compounds per gallon of solids
delivered to the coating applicator from a three-piece applicator from
a three-piece can side-seam spray operations; or
(4) 7.4 pounds of volatile organic compounds per gallon of solids
delivered to the coating applicator from end sealing compound
operations.
(d) Any source that has controlled emissions pursuant to 15A NCAC 02D
.0518(e) prior to July 1, 2000 and that has installed air pollution
control equipment in accordance with an air quality permit in order to

excluding water and exempt compounds, delivered to the coating
applicator from sheet exterior and interior basecoat and overvarnish
or two-piece can exterior basecoat and overvarnish operations;
