Current through Register Vol. 51, No. 14, July 12, 2024
A.
				  Applicability. This regulation applies to marine vessel coating operations at a
				  premises where the total potential to emit VOC emissions equals or exceeds 25
				  tons (22.75 metric tons) per year or actual emissions of 20 pounds (9
				  kilograms) per day from all marine vessel coating operations at the
				  premises.
B. Definitions. In this
				  regulation, the following terms have the meanings indicated:
(1) "Air flask coating" means a special
				  composition coating applied to interior surfaces of high pressure breathing air
				  flasks to provide corrosion resistance.
(2) "Antenna coating" means a coating applied
				  to equipment on a vessel through which electromagnetic signals must pass for
				  reception or transmission.
(3)
				  "Antifoulant coating" means a coating that is:
(a) Applied to the underwater portion of a
				  vessel to prevent or reduce the attachment of biological organisms;
				  and
(b) Registered with the EPA as
				  a pesticide under the Federal Insecticide, Fungicide, and Rodenticide
				  Act.
(4) "Chemical agent
				  resistant coatings (CARC)" means an exterior topcoat applied to military or
				  U.S. Coast Guard ships that are subject to specific chemical, biological, and
				  radiological washdown requirements.
(5) "Heat resistant coating" means a coating
				  that during normal use must withstand a temperature of at least 204°C
				  (400°F).
(6) "High-gloss coating"
				  means a coating that achieves at least 85 percent reflectance on a 60 degree
				  meter when tested by ASTM Method D-523.
(7) "High-temperature coating" means a
				  coating that during normal use must withstand a temperature of at least 426°C
				  (800°F).
(8) "Inorganic zinc
				  (high-build) coating" means a coating that contains 8 pounds (3.6 kilograms) or
				  more elemental zinc incorporated into an inorganic silicate binder that is
				  applied to steel to provide galvanic corrosion resistance.
(9) "Marine vessel coating operation" means
				  the application of coatings to a ship.
(10) "Mist/tack coating" means a low
				  viscosity, thin film, epoxy coating applied to but not limited to an inorganic
				  zinc primer.
(11) "Navigational
				  aids coating" means a coating applied to Coast Guard buoys or other Coast Guard
				  waterway markers.
(12) "Nonskid
				  coating" means a coating applied to the surfaces of a ship for the purpose of
				  providing slip resistance.
(13)
				  "Nuclear coating" means a protective coating used to seal porous surfaces such
				  as steel or concrete that otherwise would be subject to intrusion by
				  radioactive materials.
(14)
				  "Organic zinc coating" means a coating derived from zinc dust incorporated into
				  an organic binder, that:
(a) Contains more
				  than 8 pounds (3.6 kilograms) of elemental zinc per gallon of coating, as
				  applied; and
(b) Is used for the
				  express purpose of corrosion protection.
(15) "Pretreatment wash primer coating" means
				  a coating that contains a minimum of 0.5 percent acid, by weight, and is
				  applied only to bare metal to etch the surface and enhance adhesion of
				  subsequent coatings.
(16) "Rubber
				  camouflage coating" means a specially formulated epoxy coating used as a
				  camouflage topcoat for exterior submarine hulls and sonar domes.
(17) "Sealant coating" means an epoxy coating
				  applied over thermal spray aluminum surfaces.
(18) Ship.
(a) "Ship" means a marine vessel used for
				  military or commercial operations, including self-propelled vessels, those
				  propelled by other craft (barges), and navigational aids (buoys and
				  markers).
(b) "Ship" includes:
(i) All military and Coast Guard
				  vessels;
(ii) Commercial cargo and
				  passenger (cruise) ships;
(iii)
				  Ferries;
(iv) Barges;
(v) Tankers;
(vi) Container ships;
(vii) Patrol and pilot boats; and
(viii) Dredges.
(c) "Ship" does not include offshore oil and
				  gas drilling platforms unless they are moved to an on-shore marine vessel
				  coating operation.
(19)
				  "Special marking coating" means a coating that is used for safety or
				  identification applications.
(20)
				  "Specialty interior coating" means a coating used on interior surfaces aboard
				  U.S. military vessels pursuant to a coating specification that requires that
				  the coating have specified fire retardant properties and a toxicity index of
				  less than 0.03, in addition to the otherwise applicable military physical and
				  performance requirements.
(21)
				  "Thermoplastic coating" means a vinyl, chlorinated rubber, acrylic, or
				  bituminous resin coating that is used to recoat a vessel with the same type of
				  coating as its existing coating.
(22) "Undersea weapons systems coating" means
				  a coating applied to any component of a weapons system intended to be launched
				  or fired from under the sea.
(23)
				  "Weld-through (shop) preconstruction primer" means a coating which provides
				  temporary corrosion protection for steel while it remains in
				  inventory.
