Dear Mr. Richard Tharrington,
The Division of Water Quality issued a Coastal Stormwater Management Permit, Number SW 7960108
to First Investment Associates of Elizabeth City for Hampton Inn -Halstead Blvd on 2/16/1996. This
permit expires on 2/16/2006. Section .1003(h) of 15 A NCAC 2H .1000 (the stormwater rules) requires
that applications for permit renewals shall be submitted 180 days prior to the expiration of a permit and
must be accompanied by a processing fee, which is currently set at $420.00. If this is still an active
project please complete and submit the enclosed renewal application in a timely manner. If this project
has not been constructed and a permit is no longer needed, please submit a request to have the permit
rescinded. If you have sold the project, or are no longer the permittee, please provide the name, mailing
address and phone number of the person or entity that is now responsible for this permit. Enclosed is a
form for change of ownership, which should be completed and submitted if the property has changed
hands.
Your permit requires that upon completion of construction and prior to operation of the permitted
treatment units a certification of completion be submitted to the Division from an appropriate designer
for the system installed. This is to certify that the permitted facility has been installed in accordance with
the permit, the approved plans, specifications and supporting documentation. Please include a copy of
the certification with your permit renewal request and processing fee. Enclosed is a copy of a sample
certification.
You should be aware that failure to provide the Designer's Certification and the operation of a
stormwater treatment facility without a valid permit, are violations of NC General Statute 143-215.1 and
may result in appropriate enforcement action including the assessment of civil penalties of up to
$10,000 per day.
If you have any questions, please feel free to contact me or a member of the coastal stormwater staff with

Dear Mr. Tharrington:
Alan W. Klimek, P.E. Director
Division of Water Quality
This office received a Coastal Stormwater permit renewal application for the subject project on May 2,
2006. A preliminary review of your project and an onsite inspection indicates that before a State Stormwater
permit can be issued the following additional information is needed:
The stormwater pond now contains a fountain. Our Division has developed a policy for sizing
fountains in stormwater ponds (copy enclosed). Please provide documentation that the fountain in
this pond meets the criteria in the policy.
2. The onsite inspection revealed that are trees growing in the pond forebay. These should be removed
and the pond and forebay depths should be checked and cleaned as needed.
On the day of the inspection it was raining and a high volume of flow was leaving the pond. It
appeared that the small diameter orifice that allows the 1-inch storm to be drawn in 2-5 days may not
be there. Please confirm that the orifice in place.
4. Enclosed is a new operation and maintenance agreement form. Please complete the form, sign and
return.
The above requested information must be received in this office prior to August 17, 2006 or your
applications will be returned as incomplete. The return of these projects will necessitate resubmittal of all required
items including the application fees. If you need additional time to submit the required information, please mail or
fax your request for time extension to this office at the Letterhead address.
If you have questions, please feel free to contact me at [phone].

Roger,
I was able to find the vellums of the Hampton Inn plans. We didn't have blueprint paper sufficient to run
full size blueprints, so each sheet has been copied in two pieces. I have only included the two sheets
pertaining directly to stormwater.
Please call if you need any additional information.
Thank you,

DETENTION POND MAINTENANCE AGREEMENT
RECEIVED
MASNINGTON pFFICE
,1AN 3 1 996
& F_ M.
1. Operation and maintenance of the detention pond shall be the responsibility of the Owner:--__ .
2. Operation of the system is automatic upon the occurrence of a rainfall event, however, there
are several maintenance items that must be attended to. First of all, there must be a lawn
maintenance program where the grass around the pond will be kept mowed during the growing
season of the year. It is recommended for aesthetic reasons that the grass be mowed on at least a
bi-weekly basis unless actual growing conditions indicate otherwise, in which case the mowing
frequency should be modified to suit site conditions.
3. The outlet structure must be inspected periodically for obstructions and trash build-up. This
inspection should be done approximately once every three months to include inspection of the
orifice in the drawdown device to check for algae or other trash plugging the orifice, inspection
of the rip -rap filter around the riser section for trash, cut weeds or grasses which may tend to plug
the filter, inspection of the trash rack for the same type of obstructions as with the rip -rap filter
and an inspection of the barrel section for any obstructions such as limbs or anything else that
may have passed the trash rack and pose a plugging problem. Any obstructions found shall be
removed and hauled away from the pond.
4. The forebay area must be checked for sediment deposits, especially during the first year of
operation. The frequency of the forebay inspections should be monthly until all disturbed areas
have been stabilized or for a minimum of 6 months, whichever is longer. Thereafter, inspect
forebay area every three months. To perform this inspection, elevations should be taken along
the perimeter of the rip -rap flow distribution/velocity dissipation pad. The bottom should be
approximately 2' to 2 1/2' below the permanent pool elevation. If this is not the case, the rip -rap
pad will need to be removed, the sediments excavated to the levels indicated in the details, and
the rip -rap pads replaced.
S. It should be noted that in addition to the inspection frequencies recommended above, the pond
and its appurtenances should be inspected after any major storm event that may transport large
amounts of debris to the pond.
By our signature below, First Investment Associates of Elizabeth City, LLC, as Owner of the
proposed facility do hereby agree to perform the above mentioned items and maintain the
proposed facility in proper operating condition.
