Dear Mr. Cox:
Division staff has confirmed that the subject Certificate of Coverage [issued under NPDES
General Permit NCG510000] is no longer required. Therefore, in accordance with your request,
CoC NCG510437 is rescinded, effective immediately.
If in the future your company wishes to discharge wastewater to the State's surface waters, you
must first apply for and receive a new NPDES permit. Discharge of wastewater without a valid
NPDES permit will subject the responsible party to a civil penalty of up. to $25,000 per day.
If you have questions about this matter, please contact Charles Weaver of my staff at the
telephone number or address listed below.

f-Ictvrrct-�- C.. .
Dear Permittee:
Your facility is currently covered for wastewater discharge under General Permit NCG510000. This permit expires
on September 30, 2001. We are currently in the process of rewriting this permit and are scheduled to have the
permit reissued by the summer of 2001. Once the permit is reissued your facility would be eligible for continued
coverage under the reissued permit.
In order to assure your continued coverage under the general permit, you must apply to the Division of Water
Quality (DWQ) for renewal of your permit coverage. To make this renewal process easier, we are informing you in
advance that your permit will be expiring. Enclosed you will find a general permit coverage renewal application
form. This will serve as your application for renewal of your permit coverage. The application must be
completed and returned with the required information by February 28, 2001 in order to assure continued coverage
under the general permit.
Failure to request renewal within this time period may result in a civil assessment of at least $250.00. Larger
penalties may be assessed depending on the delinquency of the request. Discharge of stormwater from your facility
without coverage under a valid stormwater NPDES permit would constitute a violation of NCGS 143-215.1 and
could result in assessments of civil penalties of up to $10,000 per day.
If the subject groundwater remediation project has been terminated, please complete the enclosed rescission
request form. Mailing instructions are listed on the bottom of the form. You will be notified when the rescission
process has been completed.
If you have any questions regarding the permit coverage renewal procedures please contact the Fayetteville
Regional Office at 910-486-1541 or Aisha Lau of the Central Office Stormwater Unit at [phone], ext. 578

0) Alternative to Direct Discharge'-
address the: feasibility of,implementing each of the following non -discharge alternative's:
onnectto,a Regional:'Sewer-Collection' System
Only Cityof.Dunn:currently operates.a.1regionalsewer collection system in-the"vicinity;.
of the site ' ' As the 'attached . letter: from 'the City of Dunn illustrates' they have • refused
access for_disposal of the treated waste water -;through their sewer system..
b) Subsurface`Disposal
The. entire; site: (with the exception•:of an approximately:1,700 square'"triangular grassy.: area
located at the far 'northern: corner. of the site and adjacent to property lines on two. sides) is
currentlypaved_with, either;asphalt or;concrete :for use •.with: automotive. traffic. and ''parking
and therefore is not available for use as::part'of an infilt'ration:gallery-system Subsurface `.
soils` as classified by s-a North Carolina Licensed; Geologist while"_completing. ,the
comprehensive siteassessment::: were ::determined to :be ,Silty:clays' 'from .land'. surface ;to
depths ranging from 4 to 84eet•below land surface' across the site r
TheSoil Survey ''of Harnett County, :North' Carolina was also `reviewed -to' provide' a `
detailed description, of the sites' soils. ; The Soil Survey identified the, soils in the; vicinity of
the Site•'as'.belonging to the Norfolk -Urban. Land Complex: ,"These, soils=: are generally"'
described as well drained Norfolk;soils. and,,Urban land.' 'The Norfolk soils and,Urban-land'
occur:: so intricately mixed that they cannot be mapped' separately. Typically, the surface:"
layer of the: Norfolk soil is- brownish gray loamy sand 5 inches thick:: The subsoil is: more:
than 56 inches thick..The upper 12.inches:is:yellowish:brown,sandy'clayloam The'next'i
32 inches°-is:yellowish brown -sandy clay loam - The lower,12- inches is mottled yellowish
red and yellowish brown sandy loam"
The: fact that 'little land is available for" use';with an infiltration gallery system .and that; the
site is. -underlain by: clayey soils'; limits' this applicability of an infiltration gallery as a viable ;
option Purchasing` neighboring property -for use, as with an infiltration gallery is also;not
feasible to dire to the fact that it has. already:, been developed on all four ;sides' including
convenience. store: immediately, to the north; a motel immediately to the east, a .restaurant
immediately to" the south and.'Spring Branch. Road.. immediately.:to: the :west' with: a;
restaurant::and hotel beyond:-'
Injection Wells are also not suitable -.for'. use on the site due to the ,fact that, this,, form_ of
disposal may. change groundwatergradient across: the., site "and, result in:the migration of
contaminated groundwater towards --an ,active .water supply.: well located across_ Spring, ;

ranch. Road and approximately 100-feet west of the former UST area. ; The;former-UST„:
`area.is the source of groundwater.; contamination' at the ,site and consequently this is where
the highest levels of subsurface petroleum contamination remain
ray Irrigation
Spray: irrigation cannot apply: at the site due;to alack of land available to incorporate
an option. See part b .above
d) Waste Water- Reuse
As their is no manufacturing or processing operation' ;occurring' at the site which would
_utilizeswater then this option for treated water disposal is`also not available..

Reference: Discharge into City Sewer
Dear Mr. Will:
I am sorry it has taken me so long to get you a reply to your request to discharge
the residual from the proposed clean up site into the city sewer system. The city
has traditionally not accepted anything into the sewer system that has the
potential to upset the treatment plant. There have been other request and all
been denied.
Thank you for your patience.
Sincerely,
Joseph T. Campbell
