When a grease interceptor is abandoned, which of the following is not required?

When a grease interceptor is abandoned, notifying Public Works is not a required step in the process. Grease interceptors are typically involved in managing wastewater and preventing grease from clogging sewer systems. However, when such a unit is abandoned, the primary concerns often revolve around ensuring that the infrastructure (like sewer lines) is properly sealed or capped to prevent backflow or contamination.

The need for a permit and the installation of a cap on the sewer line are standard requirements to handle the physical changes to the plumbing system safely. Inspections are typically mandated to ensure proper abandonment procedures are followed and that all potential issues related to the interceptor's previous functions are addressed. Thus, not notifying Public Works during this process is permissible within the code, as the inspection and structural integrity of the system take precedence.
