in which these sewers will be constructed must be determined by the appropriate DEM regional office. Therefore, you are
required, prior to submittal of the application package, to submit this form, with items 1 through 7 completed, to
the appropriate Division of Environmental Management Regional Water Quality Supervisor (see page 8 of 8). At a
minimum, you must include an 8.5" by 11" copy of the portion of a 7.5 minute USGS Topographic Map which shows the
location of these sewers and the downslope surface waters in which they will be located. Identify the closest downslope
surface waters on the attached map copy. Once the regional office has completed the classification,
reincorporate this completed page and the topographic map into the complete application form and
submit the application package.

THIS APPLICATION PACKAGE WILL NOT BE ACCEPTED BY THE DIVISION OF ENVIRONMENTAL
MANAGEMENT UNLESS ALL OF THE APPLICABLE ITEMS ARE
INCLUDED WITH THE SUBMITTAL
Required Items
a. One original and one copy of the completed and appropriately executed application form. If modifications to the form are
required as a result of additional information requests by the Division, the additional information must be transmitted under
the signature of the applicant and the actual modification must be initialed by the NC Professional Engineer.
b. Two (2) sets of detailed plans and specifications signed and sealed by a North Carolina Professional Engineer. The plans must
include a general location map, a plan view of the sewer extension, a profile of the sewer extension, and must show the
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 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. 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 downstream
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
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.
f. 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.
g. A properly executed Operational Agreement (original and two copies - form provided by DEM) must be submitted if the sewer
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 necessaryfor
cland
feel free to include attachments to the application form. Such attachments will be considered as part of the application
should be numbered to correspond to the section to which they refer.
j . All materials and fees submitted in support of this request for a permit become the property of the Division of Environmental
Management; therefore, if the permit is not issued for any reason, the Division will return submitted materials only at its
option.
