Specifications may be omitted for delegated authorities. Each sheet of the plans and the first page of the specifications must be signed and sealed. Two (2) copies of the existing permit if a modification. The plans and specifications must not contain phrases (such as: FOR REVIEW ONLY, NOT FOR CONSTRUCTION, etc.) that indicate that they are anything other than final plans and specifications. However, the plans and specifications may contain: FINAL DESIGN - NOT RELEASED FOR CONSTRUCTION. C. The appropriate permit processing fee, in accordance with 15A NCAC 2H .0205(c)(5).

If the owner/authority of the wastewater treatment facility (WWT) that will be accepting the wastewater flow from this project is different from the applicant of the project, then a letter must be provided from the owner/authority of the WWTF specifying the volume of flow that will be accepted. The letter should be a recent letter and should refer to the project by the same name as that identified on the application and the plans/specifications. e. If the application is being submitted in the name of a privately owned public utility, evidence must be submitted from the Utilities Commission which demonstrates that the utility is authorized to hold the franchise for the area to be served. In the case of contiguous service areas, evidence must be provided from the Utilities Commission acknowledging these areas are covered under an existing franchise. f.
