Authorization to Construct
Wilkes County
Dear Mr. Blosser:
MA letter of request for an Authorization to Construct was received March 22, 1995 by the Division.
The request outlined ABTco's installation of an additional belt press and other appurtenances for solids
reduction. Final plans and specifications for the subject project have been reviewed and found to be
satisfactory. Authorization is hereby granted for the addition of an in-line grinder ('Muffin Monster' or
equivalent, 750 gpm recommended capacity), two centrifugal 200 gpm primary pumps, one submersible
1080 gpm DAF feed pump, one centrifugal variable speed (200 to 1200 gpm) pump for water from the
DAF unit, one 15 gpm positive displacement rotary pump for polymer feed to the DAF, one 35 gpm
positive displacement rotary pump for polymer feed to the rotary thickener and belt presses, the addition of
an Andritz 2.0 in dewatering belt press (or its equivalent) capable of dewatering 1500 lbs/hr residuals, and
all the associated valves, piping, and appurtenances with discharge of treated wastewater to the Yadkin
River in the Yadkin River Basin.
This Authorization to Construct is issued in accordance with Part III, Paragraph A of NPDES
Permit No. NC0005266 issued April 18, 1995, and shall be subject to revocation unless the wastewater
treatment facilities are constructed in accordance with the conditions and limitations specified in Permit No.
NC0005266.
The sludge generated from these treatment facilities must be disposed of in accordance with G.S.
143-215.1 and in a manner approved by the North Carolina Division of Environmental Management.
In the event that the 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 wastewater treatment or disposal facilities.
The Winston Salem Regional Office, telephone number(919) 771 - 4600, shall be notified at least
forty-eight (48) hours in advance of operation of the installed 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.

maximum, 6 months after installation of the new DAF unit(no later than January 1, 1996).
• ABTco shall conduct TSS and Settleable solids monitoring 7 days/week at the effluent.
