Dear Mr. Brotherton:
A letter of request for an Authorization to Construct was received February 26,
1988, by the Division and final plans and specifications for the subject project have
been reviewed and found to be satisfactory. Authorization is hereby granted for the
construction of a 0.032 MGD wastewater treatment facility consisting of modifications
and additions to existing facilities which will consist of the construction of a 1,592
gallon capacity chlorine contact chamber with a minimum of 30 minutes contact time,
the modification of the existing contact chamber to include baffles for use as a
dechlorination chamber with approximately 28 minutes of detention time, standby power
and housing, and all other piping and appurtenances to serve the Mr. Pisgah Lodge and
Recreational Area -Blue Ridge Parkway. Authorization to Construct is also granted for
the installation of dual 1500 gallon capacity baffled septic tanks in series to serve
as holding tanks for the wastewater dumping station near the campground at the Pit.
Pisgah Lodge and Recreational Area. -
This Authorization to Construct is issued in accordance with Part III paragraph B
of the NPDES Permit No. NCO072729 issued February 8, 1988, and shall be subject to
revocation unless the wastewater treatment facilities are constructed in accordance
with the conditions and limitations specified in Permit No. NC0072729.
The Permittee must employ a certified wastewater operator in accordance with Part
III paragraph D of the referenced permit.
The sludge generated from these treatment facilities must be disposed of in
accordance with G.S. 143-215.1 and in a manner approvable by the North Carolina
Division of Environmental Management.

The Asheville Regional Office, telephone number 704/251-6208 shall be notified at
least twenty-four (24) hours in advance of operation of these facilities so that an
in -place inspection can be made. Such notification to the Regional Supervisor shall
be made during the normal office hours from 8:00 a.m. until 5:00 p.m. on Monday
through Friday, excluding State Holidays.
In event the facilities fail to perform satisfactorily in meeting its NPDES
permit effluent limits, the Permittee shall take such immediate corrective action as
may be required by this Division, including the construction of additional wastewater
treatment and disposal facilities.
The approved design provides for the elimination of the existing polishing
lagoon, dosing siphons, surface sand filter, and nitrification field from the
treatment process; however, a valve is to be installed in the effluent line which will
enable the use of the lagoon and sand filter in emergency situations. Appropriate
sampling ports will be provided to evaluate the emergency facilities. Prior to using
the emergency facilities, plans and specifications for refurbishing and modifying (as
necessary) the sand filter, polishing lagoon or other treatment facilities must be
approved by the Division.
The Permittee should erect a sign near the mouth of the natural effluent channel
(discharge to the unnamed tributary) and immediately downstream of the discharge that
advises the presence of "Treated Domestic Wastewater."
Prior to removing any waste sludge from the Imhoff Tank, the Asheville Regional
Supervisor should be notified which wastewater treatment facility will be accepting
the waste sludge. If the existing sludge drying beds are used, the Division must
approve the disposal site for the dried sludge.
Upon completion of construction and prior to operation of this permitted
facility, a certification must be received from a professional engineer certifying
that the permitted facility has been installed in accordance with the approved plans
and specifications. Mail the certification to: Permits & Engineering Unit, Post
Office Box 27687, Raleigh, NC 27611.
One (1) set of approved plans and specifications is being forwarded to you. If
you have any questions or need additional information, please contact Mr. Randy Jones,
telephone number 919/733-5083.
Sincerely,
R. Paul Wilms
