NSR Guidance for Surface Coating Operations

Overview of air permitting requirements and options for surface coating operations. Links to relevant rules, guidance, and forms.

What type of authorization do I need?

In Texas, there are three options for obtaining authorization to emit air contaminants from a surface coating facility: De Minimis claim, Permits by Rule (PBRs), or a Case-by-Case Permit. The type of authorization required will depend on the materials and chemicals used at the facility, the processes that are conducted, and the amount of air contaminants that are emitted.

TCEQ’s Small Business and Local Government Assistance program provides guidance for the authorization of surface coating facilities, which will help you determine the appropriate authorization mechanism for your facility. This guidance includes information about air, water, and waste regulations, as well as helpful resources such as calculation spreadsheets, application checklists, etc. It is recommended that you review this guidance and determine if your facility meets the requirements for either de minimis or PBR.

Any site that does not qualify as De Minimis or cannot be authorized under a PBR must obtain a Case-by-Case permit, which requires a more stringent review. Additional guidance to assist in obtaining a Case-by-Case permit is provided below.

Case-by-Case Permit Guidance
