Startup and Shutdown Events

If no for any of the above, please explain:

Not Applicable

Do you wish to recommend a standard that would apply during startup and shutdown? If so, please:

Startup and shutdown emissions are included in 

normal operations and not differentiated.

1. Describe the event(s) to which the standard would apply

2. Provide the recommended standard (this could be an emission 

limitation, work practice, or operational standard) that would apply 

during the period

3. Provide a compliance determination method

4. Provide the basis for the recommended standard

5. Explain why and how the standard would minimize emissions during 

the event

For each emission source type, can you comply with the emissions limitation and/or work practices in the regulation 

that apply during normal operation during startup and shutdown events?
