This rule applies to all commercial and non-commercial coating applications to Group I Vehicles and Equipment and Group II Vehicles and their parts and components at facilities involved in the non-assembly line production, modification, or refinishing of motor vehicles and mobile equipment. Commercial and non-commercial facilities with coating operations considered within the scope of this rule include, but are not limited to: autobody repair/paint shops, production autobody paint shops, new car dealer repair/paint shops, fleet operator repair/paint shops, custom-made car fabrication facilities, truck body-builders, and residences. Motor vehicle assembly-line coating operations are subject to Rule 1115 - Motor Vehicle Assembly Line Coating Operations, whereas the application of coatings on a vehicle which is not self-propelled, such as trailers and mobile homes, are subject to other source specific rules contained in Regulation XI.

(b) Definitions For the purposes of this rule, the following definitions shall apply:

  1. ADHESION PROMOTER is a coating applied over both an existing non-sanded topcoat, and the coated area immediately adjacent to the non-sanded topcoat, to promote the adhesion of a subsequent topcoat. No topcoat, primer, primer sealer, or primer surfacer shall be classified as an adhesion promoter.
  2. AEROSOL COATING PRODUCT is a pressurized coating product containing pigments or resins that dispenses product ingredients by means of a propellant, and is packaged in a disposable can for hand-held application, or for use in specialized equipment for ground traffic/marking applications.
  3. ANTI-GLARE SAFETY COATING is a coating formulated to eliminate glare for safety purposes on interior surfaces of a vehicle and which shows a reflectance of 25 or less on a 60° gloss meter.
  4. BASECOAT is a pigmented topcoat which is the first topcoat applied as part of a multistage topcoat system.
  5. BASECOAT/CLEARCOAT TOPCOAT SYSTEM is a topcoat system composed of a basecoat portion and a clearcoat portion. The VOC content of a basecoat/clearcoat topcoat system shall be calculated according to the following formula:
                    VOCbc  +  2 VOCcc
      VOCms =   ------------------------
                           3

  6. Approved Emission Control System
    A person may comply with the provisions of paragraph (c)(1), by using an approved emission control system, consisting of collection and control devices, which is approved, in writing, by the Executive Officer for reducing emissions of VOC. The Executive Officer shall approve such emission control system only if the VOC emissions resulting from the use of non-compliant coatings will be reduced to a level equivalent to or lower than that which would have been achieved by the compliance with the terms of paragraph (c)(1).
    The required efficiency of an emission control system at which an equivalent or greater level of VOC emission reduction will be achieved shall be calculated by the following equation:
                         (VOCLWc)        1 - (VOCLWn.Max/Dn.Max)
    C.E. = [ 1  -  {  -------------  x -----------------------  } ]  x 100
                       (VOCLWn.Max)        1 - (VOCLWc/Dc)

    Where:
    C.E. = Control Efficiency, percent
    VOCLWc = VOC Limit of Rule 1151, less water and less exempt compounds, pursuant to paragraph (c)(1).
    VOCLWn.Max = Maximum VOC content of non-compliant coating used in conjunction with a control device, less water and exempt compounds.
    Dn,Max = Density of VOC solvent, reducer, or thinner contained in the non-compliant coating containing the maximum VOC.
    Dc = Density of corresponding VOC solvent, reducer, or thinner used in the compliant coating system = 880 g/L.

  7. Alternative Emission Control Plan
    person may comply with the provisions of paragraph (c)(1) by means of an Alternative Emission Control Plan (AECP), pursuant to Rule 108.
