What if everything we do is indoors?
You may submit a No Exposure Certification if all of your industrial materials and activities are protected by a storm resistant shelter to prevent exposure to rain, snow, snowmelt, and/or runoff. Read Appendix K of the MSGP: No Exposure Certification (PDF) (6 pp, 245K) to determine if you're eligible for exclusion from stormwater permitting.
If you're eligible, file your No Exposure Certification online.
