Yes, that might be the best instead of submitting a rescission request first. Your contact would be Thad Valentine in the
Regional Office.
Thad, see the correspondence below.

Bethany- Thank you for your response. It sounds like the first step is to contact the inspector from the regional office to
setup a site inspection, would you agree?

David,

I have to confess I'm not familiar with the procedure or approvals that a facility needs to change their SIC. I do know
that if they do change it and apply to have NCG03 coverage rescinded on that basis, the regional office will do an
inspection (as they do with any rescission request) and determine if the activities that are continuing there should have
stormwater permit coverage. Outside of the SIC, DEQ can retain an industry under NPDES through designation if there
are good reasons (material exposures, past activities, potential impact to water quality, etc.), so a mere change in SIC
won't ensure permit removal. It is very possible the region will agree coverage is no longer necessary.
I hope this helps,

Bethany- Engine Systems, Inc., has an existing NCG 030560 permit, and have asked that we inquire as to the
applicability of this permit for their operations.
As you know, the NCG 30000 permit is for metal fabrication and manufacturing. Engine Systems does not perform
manufacturing operations, but only servicing and distribution of diesel engine power products (especially commercial
diesel generators). The facility site contains more than 14,000 gallons of oil products (diesel fuel, cooling oil, and
lubricating oils).
They are considering changing their SIC and NAICS codes from:
NAIC 335312: Motor and Generator Manufacturing
NAIC 333618: Other Engine Equipment Manufacturing
SIC 34: Fabricating of Metal Products
to
NAIC 811310: Commercial and Industrial Machinery and Equipment
(except Automotive and Electronic) Repair and Maintenance
SIC 7699: Repair Shops and Related Services, Not Elsewhere Classified

Is NCG 30000 still the most appropriate permit for the facility?
Thank you for your clarification!
