I have reviewed the subject plans for stormwater management at this site. This is an after the
fact 401 Certification. There was existing impervious area on site. The applicant has proposed
constructing a wetland to serve part of the new impervious area. The applicant has proposed
converting a sediment basin into a wet pond to account for the remainder of the new impervious area.
The applicant will be treating more new impervious area than we are requiring, so I recommend that
we approve the plans as is. They are providing a wetland for part of the treatment, and both BMPs
are expected to achieve 85% TSS removal. As such, I recommend that we approve the plans.

Dear Mr. Cook:
The Wetlands Unit staff reviewed the stormwater management plans for the subject project and determined that additional
information is necessary to complete the technical review process. The required additional information is as follows:
1. Dry Basin
Per our conversation today, we discussed the possibility of retrofitting the dry sediment basin into an extended
detention wet pond. In such an event, it is my understanding that the wetland would treat part (1.17 acres) of the
new or equivalent new impervious area, and the wet pond would treat the remainder of 1.3 impervious acres plus
an additional 0.6 impervious acres (approximately). This Office would consider the above treatment to meet the
stormwater management requirement in the 401 Water Quality Certification. As such, it is my understanding that the
plans will be modified and resubmitted to this Office for review.
Division wetlands unit staff will strive to complete a final technical review within 10 working days of receipt of the
requested information. If you have any questions or would like to discuss this project, please contact me at (919) 733-
9584. Also, please note that the NCDENR StormwaterBest Management Practices Manual, April 1999, and other
documents and information can be downloaded from the Wetlands Unit web site at
http://h2o.ehnr.state.nc.us/ncwetlands/.

DEAR MR. ST.JOHN:
WE HAVE REVISED THE PLANS FOR THE REFERENCED SITE, REMOVING
THE DRY PONDS AND PIPING THE ON-SITE WATER TO A PROPOSED POND.
THIS WAS PER YOUR LETTER DATED 26 SEPTEMBER 2001.
ALONG WITH THE ENCLOSED PLANS WE ARE INCLUDING NEW
CALCULATIONS AND A REVISED OPERATION AND MAINTENANCE AGREEMENT.
THE POND HAS BEEN SIZED FOR A PERMANENT POOL WITH FLOODED
WETLAND AREA, WITH A FOREBAY AND TO CONTAIN AND SLOW RELEASE THE
1" RUNOFF VOLUME. WE HAVE INCLUDED A WETLAND PLANT LAYOUT ON
SHEET # 2.
PLEASE REVIEW AND TELEPHONE ME IF YOU HAVE ANY QUESTIONS.
THIS SYSTEM WILL PROVIDE FOR MUCH BETTER WATER QUALITY THAN WHAT
WAS EXISTING AND THAT THE VERY SMALL STREAM HAD TO FLOW THROUGH.

DWQ Project No. 010381

Dear Mr. Cook:
The Wetlands Unit staff reviewed the stormwater management plans for the subject project and determined that additional
information is necessary to complete the technical review process. The required additional information is as follows:
1. Extended Detention Wetland
In reference to our conversation. of September 24, 2001, it will be necessary to construct an extended detention
wetland to treat runoff from the new construction area. (See chapter 2 of the NC DENR Stormwater Best
Management Practices Manual.)
2. Operation and Maintenance Agreement
The operation and maintenance agreement should be modified to be compatible with an extended detention
wetland design. Changes should include the elimination of the language that indicates that vegetation will be
removed and the addition of language to indicate that the wetland vegetation will be maintained.
The operation and maintenance agreement must also be signed by the responsible party and notarized.
Division wetlands unit staff will strive to complete a final technical review within 10 working days of receipt of the
requested information. If you have any questions or would like to discuss this project, please contact me at (919) 733-
9584. Also, please note that the NCDENR Stormwater Best Management Practices Manual, April 1999, and other
documents and information can be downloaded from the Wetlands Unit web site at

BASED ON THE 401 APPROVAL LETTER, WE ARE SUBMITTING PLANS
FOR THE STORM WATER CONTROLS FOR THE REFERENCED SITE.
THE FOUR SEDIMENT BASINS HAVE WORKED EXTREMELY WELL IN
KEEPING THE SILT OUT OF THE SMALL CREEK. THESE BASINS WILL BE
CONVERTED TO PERMANENT DETENTION PONDS.
THE RIPRAP WEIRS WILL BE REMOVED FROM THE BASINS, THE RIPRAP
USED AS POND DIVIDER BERMS AND NEW DAMS CONSTRUCTED WITH OUTLET
STRUCTURES INSTALLED.
THE PIPE SYSTEMS WILL HAVE TRASH RACKS INSTALLED, BOTH OVER
THE TOP AND OVER THE DRAIN HOLES. WE WOULD LIKE TO MAKE THE DRAIN
HOLES A MINIMUM OF 1" DIAMETER. WE COULD PLACE RIPRAP OVER THE
DRAIN HOLES TO REDUCE OUTFLOW.
A COPY OF THE MAINTENANCE AGREEMENT IS ATTACHED FOR YOUR
FILE, ALONG WITH A WRITTEN STORM WATER PLAN AND CALCULATIONS.
PLEASE REVIEW AS SOON AS POSSIBLE AND APPROVE SO THAT WE CAN
GET THE PONDS COMPLETED. THANKS FOR YOUR TIME AND IF YOU HAVE ANY
QUESTIONS GIVE ME A TELEPHONE CALL.

PROPOSED STORM WATER MANAGEMENT & CHANNEL REPAIR
THERE ARE 4 SEDIMENT TRAPS CURRENTLY COLLECTING SOIL ON
THIS SITE. TWO ON EACH END OF THE PIPE LOCATION, EACH SIDE OF THE
SMALL CREEK. THESE ARE TO BE CONSTRUCTED TO THE DIMENSIONS AS
SHOWN ON THE PLANS AND CONVERTED TO STORM WATER DETENTION
PONDS.
THE LARGER POND WILL BE CONSTRUCTED AS A WET POND, SPRING
FED AND WITH AN AREA GREATER THAN THE ACTUAL STREAM AREA TO
BE COVERED BY PIPING THE STREAM.
AT BOTH ENDS OF THE 142 LINEAR FEET OF REINFORCED CONCRETE
PIPE (RCP), THE STREAM BANKS AND BOTTOM WERE DISTURBED, WITH
ALL VEGETATIVE MATTER REMOVED. THE LOWER END HAS NOW HAD
SOME RIPRAP INSTALLED. THIS ROCK AND SOIL MIX HAS SOME
VEGETATIVE GROWTH ALREADY GROWING.
AS A RESTORATION TO REMOVING THE VEGETATION, WE PROPOSE
THE FOLLOWING;
1) CONSTRUCT CONCRETE BAFFLE BLOCKS IN THE HEADWALL
FLOOR TO HELP DISSIPATE THE OUTLET VELOCITY,
2) LEAVE APPROXIMATELY 12 FEET OF RIPRAP BEYOND THE
HEADWALL FLOOR
3) RECONSTRUCT A STREAM CHANNEL AT BOTH THE UPSTREAM
END AND DOWNSTREAM END OF THE RCP. MAKE BOTTOM 4 FEET WIDE
AND SIDE SLOPES AT 2:1 SLOPES.
4) PLACE A LINER OVER THE DISTURBED STREAM AREAS, USE
APPROVED LONG TERM FABRIC.
5) PLANT GRASS OVER THE STREAM CHANNEL AREA AND PLANT 6
FOOT TALL UNDERSTORY TREES (MAXIMUM GROWTH HEIGHT OF 30
FEET) AT TWO STAGGERED ROWS AND AT 6 FOOT SPACING ALONG BOTH
SIDES OF THE STREAM BANK.

THE FOUR PONDS WILL TRAP AND HOLD WATER RUNOFF FROM
+/-95% OF THE FILLED AREA AND WILL TRAP SEDIMENT AND DO A SLOW
RELEASE OF STORM WATER. ALL THE SLOPES OVER THE PIPE WILL BE
STABILIZED AND WILL BE PROVIDED WITH A GOOD GROUND COVER.
DUE TO THE POOR CONDITION OF THE PRIOR STREAM CHANNEL,
THIS WILL GREATLY IMPROVE THE WATER QUALITY AND PROVIDE SOME
WATER QUALITY BENEFIT TO THE TOTAL AREA THAT WAS DISTURBED.
THE CONSTRUCTION WILL BE MONITORED AND AN AS-BUILT
COMPLETED ON ALL THE PONDS.

APPROVAL of 401 Water Quality Certification and ADDITIONAL CONDITIONS
Sonny Hancock
1978 Smith New Hope Road
Gastonia, NC 28054
Dear Sirs:
You have our approval, in accordance with the attached conditions and those listed
below, to place fill material in 186 linear feet of streams for the purpose of constructing a road
crossing from access and car storage at Main Street and Hwy 74 at Sonny Hancock
Automotive site as described in your application dated March 15, 2001. After reviewing your
application, we have decided that this fill is covered by General Water Quality Certification
Number 3289. This certification allows you to use Nationwide Permit Number 14 when the
Corps of Engineers issues it. In addition, you should get any other federal, state or local
permits before you go ahead with your project including (but not limited to) Sediment and
Erosion Control, Coastal Stormwater, Non-Discharge and Water Supply Water shed
regulations. This approval will expire when the accompanying 404 or CAMA permit
expires unless otherwise specified in the General Certification.
This approval is only valid for the purpose and design that you described in your
application except as modified below. If you change your project, you must notify us and you
may be required to send us a new application. If the property is sold, the new owner must be
given a copy of this Certification and approval letter and is thereby responsible for complying
with all conditions. If total wetland fills for this project (now or in the future) exceed one acre,
compensatory mitigation may be required as described in 15A NCAC 2H .0506 (h) (6) and
(7). For this approval to be valid, you must follow the conditions listed in the attached
certification and any additional conditions listed below.
1. Deed notifications or similar mechanisms shall be placed on all remaining jurisdictional
wetlands and _streams_to notify the state in-order-to assure compliance for future wetland _
and/or water impact. These mechanisms shall be put in place within 30 days of the date
of this letter or the issuance of the 404 Permit (whichever is later).
2. An additional condition is that a final, written stormwater management plan shall be
approved by this Office before the impacts specified in this Certification occur. The
stormwater management plan utilizing a constructed wetland must include plans and
specifications for stormwater management facilities designed to remove 85% TSS
according to the most recent version of the NC DENR Stormwater Best Management
Practices Manual. Also, before any permanent building is occupied at the subject site, the
facilities, as approved by this Office, shall be constructed and operational, and the
stormwater management plan, as approved by this Office, shall be implemented.

AN EXPANSION TO A. SITE CURRENTLY UNDER CONSTRUCTION FOR
BOTH ACCESS AND FOR CAR STORAGE REQUIRED THE CROSSING OF A
VERY SMALL STREAM. THE ITEM WAS DISCUSSED- WITH THE GENERAL
CONTRACTOR AND WITH THE GRADING CONTRACTOR. THE 150 FOOT RULE
WAS MADE CLEAR TO ROTH PARTIES. AND TO THE OWNER.
PLANS WERE COMPLETED AND SUBMITTED TO MOORESVILLE
REGIONAL OFFICE SHOWING 142 FEET OF PIPE AND THAT A DISSIPATER
WOULD BE PROVIDED AT THE PIPE OUTLET. LAND QUALITY APPROVED
PLAN AS A.CHANGE TO THE ORIGINAL PLAN.
THE SITE WAS CLEARED, PIPE WAS INSTALLED WITH HEADWALLS,
SEDIMENT MEASURES WERE INSTALLED AND SOIL FILL WAS PLACED
OVER THE PIPE.
WHEN . L ARRIVED AT THE SITE, IT WAS NOTED THAT SOME CHANNEL
BELOW THE PIPE OUTLET HAD ALSO BEEN DISTURBED, VEGETATION
REMOVED AND RIPRAP PLACED- IN THE CHANNEL. SO NOW WE HAVE
MORE THAN 150 FEET OF DISTURBANCE.
AS TO THE STREAM CHANNEL,.IT WAS. ONLY 2 FEET WIDE-AND HAD
ERODED TO A DEPTH OF 2.5 FEET. THE CHANNEL WAS HEAVILY SILTED,
HAD- SEVERAL TIRES IN SAME PLUS -PART OF AN OLD VEHICLE, SOME OLD
WHEELS, TRASH AND OTHER OBJECTS.
THE STREAM FLOW IS VERY SMALL AND IS_ CONVEYED FOR
SEVERAL HUNDRED FEET THROUGH A-54 A INCH RCP UNDER INTERSTATE
MR. DORNEY
12 MARCH 2001
PAGE#2
85 PRIOR TO ENTERING THIS SITE APPROXIMATELY 50 FEET BELOW THE
NEW PIPE OUTLET THE STREAM ENTERS INTO ANOTHER PIPE SYSTEM
SEVERAL HUNDRED FEET OF 5-4 - 0 INCH CMP.
WE HAVE SUBMITTED A COPY OF THE APPLICATION TO THE CORP
OF ENGINEERS IN ASHEVILLE_ AND HA-VF- REQUESTED AN ON-SITE
MEETING.
PLEASE REVIEW THE PRE- CONSTRUCTION APPLICATION AND
TELEPHONE ME TO DISCUSS. WE CAN RECONSTRUCT THE OUTLET
CHANNEL AND ADD SOME BUSHES OR OTHER. THINGS. TO BF-LESS. TH?AN
THE 150 FEET.
YOUR INDULGENC-t WOULD BE APPRECIATED.
