Air management New or expanding business?

Are you starting a new small business? Click the "New Business" button below.

Are you expanding your business? Click the "Expanding Business" button below. Five types of changes can meet the definition of expanding a business:

  • Construction — to build an entirely new facility or add new equipment at an existing facility; includes reconstruction and replacement (see below)
  • Modification — a physical change to, or change in, the method of operation that produces either more air emissions of the same type or different or "new" air emissions
  • Reconstruction — to remove old and substitute new components that exceed 50% of the capital cost of building a new source
  • Replacement — to dismantle and substitute a process or facility with a similar one
  • Relocation — to remove a process or facility from one location and place it at a different site or within the same property boundaries
