Form 2A has been developed in a modular format and consists of a "Basic Application Information" packet
and a "Supplemental Application Information" packet. The Basic Application Information packet is divided
into two parts. All applicants must complete Parts A and C. Applicants with a design flow greater than or
equal to 0.1 mgd must also complete Part B. Some applicants must also complete the Supplemental
Application Information packet. The following items explain which parts of Form 2A you must complete.
BASIC APPLICATION INFORMATION:
A. Basic Application Information for all Applicants. All applicants must complete questions A.1 through A.8. A treatment works
that discharges effluent to surface waters of the United States must also answer questions A.9 through A.12.
B. Additional Application Information for Applicants with a Design Flow i 0.1 mgd. All treatment works that have design flows
greater than or equal to 0.1 million gallons per day must complete questions B.1 through B.6.
C. Certification. All applicants must complete Part C(Certification).
SUPPLEMENTAL APPLICATION INFORMATION:
D. Expanded Effluent Testing Data. A treatment works that discharges effluent to surface waters of the United States and meets
one or more of the following criteria must complete Part D(Expanded Effluent Testing Data):

Flow Diagram Narrative for the Town of Maiden WWTP
The Town of Maiden collects and treats domestic and industrial wastewater from
roughly 55 miles of sewer system. The daily average for flow at the WWTP is
currently 0.30136 MGD, based off an annually calibrated influent flow meter.
The raw influent comes into the facility's headworks where it goes through a
mechanical screen and grit removal system. The flow is evacuated from the
headworks by a dry well lift station with two 50 hp influent pumps. An Influent
headworks bypass connection is plumbed into the force main if we ever needed to
bypass around the headworks and/or lift station for maintenance or emergency
applications. The influent pumps transfer the wastewater from the headworks to
either SBR #1 or SBR #2. Electronic actuators controlled by a PLC control the
open and close functions of both sets of influent and Effluent valves.
At the beginning of each SBR's cycle there is a minimum level of 9.1 feet of
activated sludge. For 120 minutes one of the SBR's will accept raw wastewater
while intermittingly mixing and aerating called the react fill stage. Once the 120
minute react fill stage is complete the other basin will begin accepting influent as it
start its cycles. The next stage, after react fill, is a 30 minute react stage where the
basin is adequately mixed and aerated to further treat the raw water with the
microorganisms, with no additional influent being added during this cycle. After
the react stage the SBR falls into a settling mode where the sludge settles and then
the treated water is decanted with a mechanical decanter to an equalization basin
for final aeration and controlled release to the contact chamber for disinfection.
After adequate disinfection time with sodium hypochlorite the treated effluent has
the chorine residual removed with sodium bisulfite and is then discharged a few
hundred feet away into Clark's Creek.
At the end of each 4-hour cycle each SBR wastes from the settled sludge for a
programmed time interval. The wasted sludge is pumped over and stored in one of
two available aerobic digesters where it digests until the sludge is hauled to the
Veolia Compost Plant in Hickory. During sludge hauling operations the digester
blowers are usually taken out of service to allow the sludge to settle and compact,
so we can decant the clear water that develops on the digesters back to the
headworks and be able to haul a thicker sludge. The Veolia Compost Plant makes
a class "A" product from our sludge and other area municipalities.
There is also a 12" drain line that runs from the contact chamber back to the
headworks. This drain line provides means for the chlorine contact chamber and
SBR's to be drained. This drain line also collects wastewater from a trench-drain
in our storage building.

Sludge Management Plan
Town of Maiden WWTP
Updated: 01/27/15
Sludge that is generated during the wastewater treatment process is wasted into one of two
aerobic digesters and is later transferred and disposed of through means of composting. The
sludge from the digesters is transferred a load(6,000 gallons)at a time to a 7,000 gallon holding
tank. From this holding/transfer tank the digested sludge is pumped into a 7,000 gallon tanker
trailer pulled by a Road Tractor. The sludge is then hauled to the Regional Compost Facility
(RCF) in Hickory,NC, which is operated by Veolia Water North America. The permit number
for the RCF is WQ0004563. The final product from the compost facility meets all guidelines
outlined in the permit and 503 Regulations for Class A sludge.
