Plastic Parts and Products surface coating mact summary

4. What is an affected source in this source category?

An affected source is defined as a stationary source, a group of stationary sources, or part of a stationary source to which a specific emission standard applies. This rule defines the affected source as the collection of all operations associated with the surface coating of plastic parts and products within each of the four subcategories (general use, TPO, automotive lamps, and assembled on-road vehicle). 

If application to a substrate occurs, these operations include preparation of a coating for application (e.g., mixing with thinners and/or other additives); surface preparation of the plastic parts and products (including the use of a cleaning material to remove dried coating); coating application and flash off; drying and/or curing of applied coatings; cleaning of equipment used in surface coating; storage of coatings, thinners and/or other additives, and cleaning materials; and handling and conveyance of waste materials from the surface coating operations.

The coating operation does not include the application of coatings using hand-held non-refillable aerosol containers, touch up markers, marking pens, or the application of paper film or plastic film that may be pre-coated with an adhesive by the manufacturer.
