Apply for a grease interceptor variance, waiver, or conditional waiver from a local FOG program

Steps

1. Confirm the specific local FOG program's variance/waiver categories and eligibility criteria, since programs commonly tier requests (e.g., limited exemptions for very low-FOG-risk operations versus variances allowing an alternative device type such as a hydromechanical interceptor in place of a required gravity interceptor)
2. Prepare the required application package, typically including a site plan showing property lines, easements, existing structures, and any physical features constraining interceptor installation, a description of food processing/cooking operations, a full kitchen equipment list, and estimated wastewater volume/type
3. Be prepared to carry the burden of proof: most programs place the burden on the food service establishment to demonstrate that installing the normally required interceptor is not feasible or not applicable to its specific operation
4. Submit the application with any required fee to the local FOG program authority and await a written determination before proceeding on the assumption the variance/waiver will be granted
5. Confirm the approval's validity period and renewal process, since some programs grant time-limited approvals (commonly renewed annually) rather than a permanent exemption
6. Maintain any conditions attached to the approval (e.g., more frequent inspections, mandatory alternative BMPs) since a granted variance/waiver is typically conditional, not an unconditional release from all FOG control obligations
