Dear Mr. Fitzgerald:
In accordance with your renewal request received July 26, 2001, we are forwarding herewith
Permit No. W00005381, dated March 11, 2002, to EMC Corporation for the continued operation of the
subject wastewater treatment and spray irrigation facilities. This cover letter shall be considered a part
of this permit and is therefore incorporated therein by reference.
Though the existing spray fields are currently dormant, this permit renewal is being issued so
that the Permittee may proceed with the satisfactory closure of the lagoon and spray field, properly
dispose of residual solids, abandon and salvage the wastewater collection, treatment and disposal
facilities, and reclamation of the spray field site in concurrence with their connection to the Town of
Apex's sanitary sewer system. Upon completion of the above, the Permittee shall make request to the
Division of Water Quality to rescind this permit.
Please read your permit carefull . Several permit conditions have been modified and/or
excluded since the last issuance of the permit. Previous Permit Conditions 1.4, 11.2, 111.2 - 111.7, and VIA
have been removed from the permit as requested. These conditions are no longer applicable upon
EMC Corporation's connection to the Town of Apex's sewer system. Additionally, please note Permit
Conditions IVA - IV.4 as they relate to the satisfactory closure of the lagoon and spray field, and proper
disposal of the residuals.
This permit shall be effective from the date of issuance until. February 28, 2007, shall void
Permit No. WQ0005381 issued June 2, 2000, and shall be subject to the conditions and limitations as
specified therein. Please pay particular attention to the monitoring requirements in this permit. Failure
to establish an adequate system for collecting and maintaining the required operational information will
result in future compliance problems.
If any parts, requirements, or limitations contained in this permit are unacceptable, you have the
right to request an adjudicatory hearing upon written request within thirty (30) days following receipt of
this permit. This request must be in the form of a written petition, conforming to Chapter 150B of the
North Carolina General Statutes, and filed with the Office of Administrative Hearings, 6714 Mail Service
Center, Raleigh, NC 27699-6714. Unless such demands are made, this permit shall be final and
binding.

In accordance with the provisions of Article 21 of Chapter 143, General Statutes of North Carolina as
amended, and other applicable Laws, Rules, and Regulations
PERMISSION IS HEREBY GRANTED TO
EMC Corporation
Wake County
FOR THE
continued operation of a 7,500 -gallon per day spray irrigation treatment and disposal facility consisting of a
30,000 -gallon per day wastewater treatment facility, a 44,160 cubic foot storage lagoon, a pump station,
three (3) acres of spray irrigation field with 41 sprinklers, approximately 300 linear feet of 6 -inch effluent
sewer, and all associated valves, piping, and appurtenances to serve the EMC Corporation, with no
discharge of wastes to the surface waters, pursuant to the request received July 26, 2001, and in conformity
with the project plan, specifications, and other supporting data subsequently filed and approved by the
Department of Environment and Natural Resources and considered a part of this permit.
This permit shall be effective from the date of issuance until February 28, 2007, shall void Permit No.
WQ0005381 issued June 2, 2000, and shall be subject to the following specified conditions and limitations:
I. PERFORMANCE STANDARDS
The spray irrigation facilities shall be effectively maintained and operated at all times so that
there is no discharge to the surface waters, nor any contamination of ground waters which will
render them unsatisfactory for normal use. In the event that the facilities fail to perform
satisfactorily, including the creation of nuisance conditions or failure of the irrigation area to
adequately assimilate the wastewater, the Permittee shall take immediate corrective actions
including those actions that may be required by the Division of Water Quality (Division), such as
the construction of additional or replacement wastewater treatment and disposal facilities.
2. The issuance of this permit shall not relieve the Permittee of the responsibility for damages to
surface or groundwaters resulting from the operation of this facility.
3. The residuals generated from these treatment facilities must be disposed in accordance with
General Statute 143-215.1 and in a manner approved by the Division.

Permit No. W00005381
March 11, 2002
4. The following buffers shall be maintained:
a) 400 feet between wetted area and any residence or places of public assembly und',
separate ownership,
b) 150 feet between wetted area and property lines,
c) 100 feet between wetted area and wells,
d) 100 feet between wetted area and drainageways or surface water bodies,
e) 50 feet between wetted area and public right of ways,
f) 100 feet between wastewater treatment units and wells, and
g) 50 feet between wastewater treatment units and properly lines.
Some of the buffers specified above may not have been included in previous permits for this
waste treatment and disposal system. These buffers are not intended to prohibit or prevent
modifications, which are required by the Division, to improve performance of the existing
treatment facility. These buffers do, however, apply to modifications of the treatment and
disposal facilities which are for the purpose of increasing the flow that is tributary to the facility.
These buffers do apply to any expansion or modification of the spray irrigation areas and apply in
instances in which the sale of property would cause any of the buffers now complied with, for the
treatment and disposal facilities, to be violated. The applicant is advised that any modifications
to the existing facilities will require a permit modification.
5. This permit shall become voidable if the soils fail to adequately assimilate the wastes and may
be rescinded unless the sites are maintained and operated in a manner which will protect the
assigned water quality standards of the surface waters and ground waters.
11. OPERATION AND MAINTENANCE REQUIREMENTS
1. The facilities shall be properly maintained and operated at all times.
2. A suitable year round vegetative cover shall be maintained.
I Wastewater shall not be applied in inclement weather or until 24 hours following a rainfall event
of 112 -inch or greater in 24 hours. Any residuals disposal measures must first be approved by
the Division of Water Quality.
4. Adequate measures shall be taken to prevent wastewater runoff from the spray field.
5. The facilities shall be effectively maintained and operated as a non -discharge system to prevent
the discharge of any wastewater resulting from the operation of this facility.
6. The application rate shall not exceed a cumulative loading of 45.0 inches over any twelve (12)
month period at an instantaneous application rate that does not cause runoff.
7. No type of wastewater or residual solids other than that from EMC Corporation shall be sprayed
onto the irrigation area.
8. No traffic or equipment shall be allowed on the disposal area except while installation occurs or
while normal maintenance is being performed.
9. Public access to the land application sites shall be controlled during active site use. Such
controls may include the posting of signs showing the activities being conducted at each site.
