Air dried coating means a coating that is dried by the use of air or forced warm air at temperatures up to 1940F (900C).
Antenna coating means a coating labeled and formulated exclusively for application to equipment and associated structural appurtenances that are used to receive or transmit electromagnetic signals.
Touch-up coating means a coating used to cover minor coating imperfections appearing after the main coating operation.
Floor coating means an opaque coating that is labeled and designed for application to flooring, including but not limited to, decks, porches, steps, and other horizontal surfaces which may be subject to foot traffic.
Metallic coating means a coating which contains more than five grams of metal particles per liter of coating, as applied. Metal particles are pieces of a pure elemental metal or a combination of elemental metals.
Nitrogen oxides means nitric oxide and nitrogen dioxide, expressed as nitrogen dioxide (NO2);
Coating means a material applied onto or impregnated into a substrate for protective, decorative, or functional purposes. Such materials include, but are not limited to, paints, varnishes, sealers, and stains.
Faux finishing coating means a coating labeled and formulated as a stain or a glaze to create artistic effects including, but not limited to, dirt, old age, smoke damage, and simulated marble and wood grain.
Diatomaceous earth filtration means a process resulting in substantial particulate removal in which a precoat cake of diatomaceous earth filter media is deposited on a support membrane (septum), and while the water is filtered by passing through the cake on the septum, additional filter media known as body feed is continuously added to the feed water to maintain the permeability of the filter cake.
Surface waters means all waters of the state as defined in G.S. 143-212 except underground waters
Membrane filtration means a pressure or vacuum driven separation process in which particulate matter larger than 1 micrometer is rejected by an engineered barrier, primarily through a size-exclusion mechanism, and which has a measurable removal efficiency of a target organism that can be verified through the application of a direct integrity test. This definition includes the common membrane technologies of microfiltration, ultrafiltration, nanofiltration, and reverse osmosis.
Nuclear coating means any protective coating used to seal porous surfaces, such as steel or concrete, that otherwise would be subject to intrusion by radioactive materials. These coatings must be resistant to long term (service life) cumulative radiation exposure (ASTM D4082-83**), relatively easy to decontaminate (ASTM D4256-83**), and resistant to various chemicals to which the coatings are likely to be exposed (ASTM 3912-80**). General protective requirements are outlined by the Department of Energy (formerly United States Atomic Energy Commission Regulatory Guide 1.54**).
Irrigation means application of water to land areas to supply the water needs of
Roll coating means the application of a coating material to a substrate by means of hard rubber or steel rolls.
Flat coating means a coating that is not defined under any other definition in this section and that registers gloss less than 15 on an 85-degree meter or less than 5 on a 60-degree meter.
Surface mining means mining by removing the overburden lying above the natural deposits and excavating directly from the natural deposits exposed, or by excavating directly from deposits lying exposed in their natural state and shall include dredge operations conducted in or on natural waterways or artificially created waterways within the state.
Undercoating means any aerosol product designed to impart a protective, non-paint layer to the undercarriage, trunk interior, and/or firewall of motor vehicles to prevent the formation of rust or to deaden sound. “Undercoating” includes, but is not limited to, rubberized, mastic, or asphaltic products.
Asphalt means a dark brown to black cement-like material (solid, semisolid, or liquid in consistency) in which the predominating constituents are bitumens which occur in nature as such or which are obtained as residue in refining petroleum.
Dip coating means the application of a coating material to a substrate by dipping the part into a tank of the coating material.
Surface water means all water which is open to the atmosphere and subject to surface runoff.
Infiltration means water other than wastewater that enters a sewer system (including sewer system and foundation drains) from the ground through such means as defective pipes, pipe joints, connections, or manholes. Infiltration does not include, and is distinguished from, inflow.
Geothermal fluid means water in any form at temperatures greater than 120
Oxides of nitrogen means the sum of the volume mixing ratio (ppbv) of nitrogen monoxide (nitric oxide) and nitrogen dioxide expressed in units of mass concentration of nitrogen dioxide (µg/m3);
Flow coating means a coating labeled and formulated exclusively for use by electric power companies or their subcontractors to maintain the protective coating systems present on utility transformer units.
Permeable pavement means paving material that absorbs water or allows water to infiltrate through the paving material. "Permeable pavement" materials include porous concrete, permeable interlocking concrete pavers, concrete grid pavers, porous asphalt, and any other material with similar characteristics.
Automotive windshield washer fluid means any liquid designed for use in a motor vehicle windshield washer system either as an antifreeze or for the purpose of cleaning, washing, or wetting the windshield. Automotive windshield washer fluid does not include fluids placed by the manufacturer in a new vehicle.
