ENVIRONMENTAL
HEALTH
IMPROVEMENT PERMIT
& CONSTRUCTION AUTHORIZATION
APPLICATION
INFORMATION
- What’s it all about?
An Improvement Permit and
Construction Authorization are the permits needed to install
a septic system. These permits are required before a building
permit can be obtained for a house, place of business, or any
structure that has indoor plumbing. The Environmental Health
office makes sure that the proposed site for the structure
meets the laws and rules of North Carolina as described in
the Laws and Rules for Sewage Treatment and Disposal
Systems. This is sometimes referred to as "perking
the land". It is recommended that you allow us to
evaluate a potential house site before you purchase
the property to make sure the property can support a septic
system.
- What is my responsibility?
A site plan must accompany
your application (see separate site plan worksheet). The site
plan must show the desired structure size and location
(measured in feet from the property lines), and any other
pertinent information such as existing wells, power-lines,
right-of-ways, easements, etc. A site plan worksheet will be
given to you at the time you apply and may be completed at
home. However, we cannot evaluate your lot until the
completed worksheet has been submitted to us.
The property corners and
desired structure location must be clearly marked on the lot
and must correspond with the site plan. Flags will be given
to you when you apply that you may place on the corners of
the property and desired structure location. The property
must not be over-grown to the extent that we cannot perform
our job. You may be asked to partially clear the property if
it is so thick that we cannot access it.
You will be given a blue
flag at the time you apply. Place the blue flag beside the
road in line with the proposed structure location. The
information on your application will be forwarded to the 911
Addressing Office. They will assign a 911 address based on
the information and the location of the blue flag. The 911
address must be assigned prior to issuance of the Improvement
Permit.
It is your responsibility
to check with other agencies that may require approval before
you apply with us. Examples: zoning requirements, wetland
designation, extra-territorial jurisdiction, etc.
- What do I need to know about my
permits?
Attached to the
Construction Authorization will be a plot plan showing the
property and the location of the septic system on the
property. If the soil and site conditions allow, the septic
system will be located near your desired structure location
to permit gravity sewage flow from the structure to the tank.
Sometimes, the soil and
site conditions may restrict the location of the septic
system to a specific area. If your desired structure location
cannot access the septic system by gravity sewage flow, then
you may need to relocate the structure. If the structure
cannot be relocated, a sewage effluent pump may be required
to access the system.
Once a permit has been
issued, care must be taken to locate the structure and
assemble the plumbing to accommodate the septic system as
specified on the permit. For example, if a permit specifying
gravity sewage flow has been issued, the structure location
and/or plumbing depth should not prevent gravity sewage flow.
If it does, a Revision must be requested ($75.00) that may
require a sewage effluent pump.
- What types of septic systems
are available?
As part of the application, you will be
asked what type of septic system you desire. Your choices
are:
Conventional System:
In-ground, gravity flow system. This system is the type
we would normally design if the soil and site conditions
meet all the laws and rules.
Modified
Conventional System: The soil and site conditions may
require the system to be modified in order to meet the rules.
These modifications may include installing the system
shallow, drainage, gravelless trenches, or interceptor
drains.
Alternative Sewage
System: The soil and site conditions may require the
use of an alternative system. An alternative system may
include a low-pressure pipe system, a fill (mound)
system, or aerobic sewage treatment units (ATU).
Experimental or
Innovative System: These systems are not specifically
described in the rules. An experimental system is
approved by the State as part of a research or testing
program. An innovative system has received approval by
the State after meeting the standards set forth in the
approval process. Approved innovative systems include
polystyrene aggregate systems and chamber systems.

- Fee Refunds
You may request a fee
refund within 90 days of the last service rendered. If
the site is never evaluated because you have failed to
provide us with all the information needed, then a full
refund can be requested within 90 days of the application
date. If the site has been evaluated and found to be
unsuitable for a septic system, then a refund can be
requested 90 days from the evaluation date for half of
the fee paid. However, if you have an alternate site that
you would like evaluated, you may request the fee be
transferred to the new site.
I have read and understand the
above information. I understand that I have certain
responsibilities that must be fulfilled before Environmental
Health can evaluate my site. If you have questions about any part
of this process, please do not hesitate to call us at (910)
862-6900. Our office hours are 8:30-5:00 Monday through Friday.
It is a pleasure to serve you.
