15A NCAC 02T .0105—Variance/Alternative Design Request Application
HDR Project Number 10328292
On behalf of Toyota,enclosed please find the following variance application and supporting documents for the City of
Greensboro Megasite Water and Sewer Improvements Phase II Project for your review and approval:
1. One original of the Variance/Alternative Design Request Application
2. $600 Application Fee
3. Plan sheet
4. Sewer Fast Track WQ0044093
We are requesting a variance due to the design conditions and install conditions changed and we do not have the cover
NCDEQ requires over PVC pipe.
NCAC 02T.305(g)(4)Requesting coverage under a stream for gravity sewer main.We have a 24"gravity main under a
stream with just over a foot of cover and is encased in concrete.The pipe is C-900 DR-18,we are requesting to leave the
pipe as is and finish the stabilization for maintenance corridor per City of Greensboro detail(attached).Our survey and
actual conditions changed between time of design and time of construction.Approximately 1,500 LF up stream there is
a force main discharging into a manhole and there will be 2 other force main discharges added to the same manhole in
the future.The pipe being C-900 PVC will be better at handling the corrosive gases.
The pipe being encase in concrete will protect the pipe.The MDC discuss sewers in relation to streams and other water
bodies.One foot of cover where the sewer is located in rock.
Will the pipe being encased in concrete satisfy this requirement.
Should you have any questions or need additional information,please do not hesitate to contact me.
Sincerely,
HDR Engineer' the Carolinas

of adequate wastewater transport, such as mechanical or electrical failures of pumps, line
blockage or breakage, etc.; or
b. Any SSO and/or spill over 1,000 gallons; or
c. Any SSO and/or spill, regardless of volume,that reaches surface water
Voice mail messages or faxed information is permissible, but this shall not be considered as the initial
verbal report. Overflows and spills occurring outside normal business hours may also be reported to
the Division of Emergency Management at telephone number [phone] or [phone].
Persons reporting any of the above occurrences shall file a spill report by completing and submitting
Part I of Form CS-SSO (or the most current Division approved form) within five days following first
knowledge of the occurrence. This report must outline the actions taken or proposed to be taken to
ensure that the problem does not recur. Part II of Form CS-SSO(or the most current Division approved
form) can also be completed to show that the SSO was beyond control. [G.S. 143-215.1C(a1)]
6. Construction of the gravity sewers, pump stations, and force mains shall be scheduled so as not to
interrupt service by the existing utilities nor result in an overflow or bypass discharge of wastewater
to the surface waters of the State. [15A NCAC 02T.0108(b)]
7. Upon completion of construction and prior to operation of these permitted facilities, the completed
Engineering Certification form with checklist attached to this permit shall be submitted with the
required supporting documents to the address provided on the form. A complete certification is one
where the form is fully executed and the supporting documents are provided as applicable. Any
wastewater flow made tributary to the wastewater collection system extension prior to completion
of this Engineer's Certification shall be considered a violation of the permit and shall subject the
Permittee to appropriate enforcement actions.
A complete certification is one where the form is fully executed and the supporting documents are
provided as applicable. Supporting documentation shall include the following:
a. One copy of the project construction record drawings(plan & profile views of sewer lines&force
mains) of the wastewater collection system extension. Final record drawings should be clear on
the plans or on digital media (CD or DVD disk) and are defined as the design drawings that are
marked up or annotated with after construction information and show required buffers,
separation distances, material changes, etc.
b. One copy of the supporting applicable design calculations including pipe and pump sizing,velocity,
pump cycle times, and level control settings, pump station buoyancy, wet well storage, surge
protection, detention time in the wet well, and force main, ability to flush low points in force
mains with a pump cycle, and downstream sewer capacity analysis. If a portable power source or
pump is dedicated to multiple stations, an evaluation of all the pump stations' storage capacities
and the rotation schedule of the portable power source or pump, include travel timeframes,shall
be provided.
c. Changes to the project that do not result in non-compliance with this permit, regulations, or the
Minimum Design Criteria should be clearly identified on the record drawings, on the certification
in the space provided, or in written summary form.
Page 6of7

Prior to Certification (Final or Partial): Permit modifications are required for any changes resulting
in non-compliance with this permit (including but not limited to pipe length changes of 10% or
greater, increased flow, pump station design capacity design increases of 5% or greater, and
increases in the number/type of connections), regulations, or the Minimum Design Criteria.
Requested modifications or variances to the Minimum Design Criteria will be reviewed on a case-by-
case basis and each on its own merit. Please note that variances to the Minimum Design Criteria
should be requested and approved during the permitting process prior to construction. After-
construction requests are discouraged by the Division and may not be approved, thus requiring
replacement or repair prior to certification & activation. [15A NCAC 02T .0116]
8. Gravity sewers installed greater than ten percent below the minimum required slope per the Division's
Gravity Sewer Minimum Design Criteria shall not be acceptable and shall not be certified until
corrected. If there is an unforeseen obstacle in the field where all viable solutions have been
examined, a slope variance can be requested from the Division with firm supporting documentation.
This shall be done through a permit modification with fee. Such variance requests will be evaluated
on a case-by-case basis. Resolution of such request shall be evident prior to completing and submitting
the construction certification. [ 15A NCAC 02T.0105(n)]
9. A copy of the individual permit and construction record drawings shall be maintained on file by the
Permittee for the life of the wastewater collection facilities. [15A NCAC 02T .0116]
10. Failure to abide by the conditions and limitations contained in this permit; 15A NCAC 02T; the
Division's Gravity Sewer Design Criteria adopted February 12, 1996 as applicable; the Division's
Minimum Design Criteria for the Fast-Track Permitting of Pump Station and Force Mains adopted June
1, 2000 as applicable; and other supporting materials may subject the Permittee to an enforcement
action by the Division, in accordance with North Carolina General Statutes§143-215.6A through §143-
215.6C, construction of additional or replacement wastewater collection facilities, and/or referral of
the North Carolina-licensed Professional Engineer to the licensing board. [15A NCAC 02T .0108(b-c)]
11. In the event that the wastewater collection facilities fail to perform satisfactorily, including the
creation of nuisance conditions,the Permittee shall take immediate corrective action, including those
as may be required by this Division, such as the construction of additional or replacement facilities.
[15A NCAC 02T .0110; 15A NCAC 02T .0108(b)]
12. The issuance of this permit shall not exempt the Permittee from complying with any and all statutes,
rules, regulations,or ordinances that may be imposed by the Division any other Federal,State,or Local
government agencies which have jurisdiction or obtaining other permits which maybe required by the
Division or any other Federal, State, of Local government agencies. [G.S. 143-215.1(b)]
