# §63.3093. What operating limits must I meet?

- (a) You are not required to meet any operating limits for any coating operation(s) without add-on controls, nor are you required to meet operating limits for any coating operation(s) that do not utilize emission capture systems and add-on controls to comply with the emission limits in [§ 63.3090](/cfr/40/63.3090.md) or [§ 63.3091](/cfr/40/63.3091.md).
- (b) Except as provided in [paragraph (d)](#d) of this section, for any controlled coating operation(s), you must meet the operating limits specified in table 1 to this subpart. These operating limits apply to the emission capture and add-on control systems on the coating operation(s) for which you use this option, and you must establish the operating limits during performance tests according to the requirements in [§ 63.3167](/cfr/40/63.3167.md). You must meet the operating limits at all times after you establish them.
- (c) If you choose to meet the emission limitations of [§ 63.3092(b)](/cfr/40/63.3092.md?p=b) and the emission limits of [§ 63.3090(b)](/cfr/40/63.3090.md?p=b) or [§ 63.3091(b)](/cfr/40/63.3091.md?p=b), then except as provided in [paragraph (d)](#d) of this section, you must operate the capture system and add-on control device used to capture and control emissions from your electrodeposition primer bake oven(s) so that they meet the operating limits specified in Table 1 to this subpart.
- (d) If you use an add-on control device other than those listed in Table 1 to this subpart, or wish to monitor an alternative parameter and comply with a different operating limit, you must apply to the Administrator for approval of alternative monitoring under [§ 63.8(f)](/cfr/40/63.8.md?p=f).
