proximity of the sewer extension to other utilities and natural features. 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 plants 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 my contain: FINAL DESIGN — NOT RELEASED FOR CONSTRUCTION.
e. Two copies of all calculations, including pump selection, friction calculations, cycle time, pump curves (including system
curves applicable with one pump running, two pumps running, three pumps running, etc.), and evaluation of downstrem pump
stations. These items must be submitted under the signature and seal of the NC Professional Engineer.
d. The appropriate permit processing fee, in accordance with 15A NCAC 2H .0205( c )(5). The fee for sewer extensions for
nondelegated municipalities is $400. The fee for sewer extensions for delegated municipalities (applies only to those
governmental jurisdictions that have specific delegation review authority, as granted by the Environmental Management
Commission) is $200. Name changes without other modifications are $100.
e. If the owner/authority of the wastewater treatment facility (WWTF) 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

extension will be serving single family residences, condominiums, mobile homes, or town houses and if the subject sewer
extension is owned by the individual residents, a homeowners association, or a developer.
h. The downslope surface waters classification must be determined by the appropriate DEM regional office, using page 5 of 8 of
this form, prior to the submittal of the application package to the Water Quality Permits and Engineering Unit. Once the
regional office has completed the classification, page 5 of 8 should be reincorporated into the application package and the
entire application package may then be submitted to Water Quality Permits and Engineering Unit.
i. A cover letter, which briefly describes the project, should be included with each application package. If necessary for clarity,
feel free to include attachments to the application form. Such attachments will be considered as part of the application and
should be numbered to correspond to the section to which they refer.
