Project Description
Tallwood Estates WWTP Replacement
Union County Public Works (UCPW) proposes to construct a replacement 50M00 gallon
per day wastewater treatment plant (WWTP) in IJnion County adjacent to the Tallwood
Estates subdivision. Tallwood Estates subdivision is located along Brief Road near
Concord Highway (US 601) in northern Union County, NC. The original developer
constructed the existing residential WWTP to serve the area in approximately 1989. The
WWTP was later acquired by UCPW who is now responsible for operation and
maintenance of the facility.
The existing WWTP is an above -ground steel extended aeration -type package plant.
Repairs have been rnade over the years however it has come to the point that the
existing facilities are structurally impaired and the facility no longer meets redundancy
requirernents for operation. The proposed project includes constructing a new WWTP
to replace the existing facilities and the dernolition of the existing facilities once the new
WWTP is activated and placed into service. The new WWTP will include the following;
4
Flow equalization
Aeration tanks
Aeration system.
Secondary clarifiers
■ Cloth disk tiltration
Sludge storage
Reuse of existing ultraviolet (UV) disinfection
Replace existing submersible influent pumps with new equipment
The proposed replacement fa
ies have been designed for the following flow and

this development and: discuss;temporary; alternatemeans for disinfection of tbe.effluent,
If chlorine compounds are.used as: temporary means of disinfection, the total residual ehlonne:(TRC)
concentiatton.of the effluent must be monitored on a daily basis while this method of disinfection: is in
use and values must be reported on :the discharge monitoring report: TRCin the,cfuent may not
exceed 17 }tgtL; therefore, dechlorination, methods may also be necessary to ensure protection of water
quality inthe receiving stream:
The Division shall cansider all effluent TR:C values reported below 50 .zg/L to he in compliance with
the permit. Howeuer, the l ennittee shall continue to record and:submit all values reported by a North
Ca ina.certified laboratory (including field certified), even if these values fall below 50 µg/L.
U'se of'a disinfection system other than the pernittedUV `system during circumstances not deemed as
emergency and/or temporary (replacement of lamps, lamp.cleaning or maintenance, etc.) will be
coltsidered a violation of the terms of this,errr►it.

RESIDUALS MANAGEMENT PLAN
Tallwood Estates WWTP
NPDES No. NC0069523
Union County, North Carolina
Residuals generated at the Ta!Iwood Estates WWTP will be transported via vacuum truck to
Union County's Crooked Creek WWTP (NC0069841). All residuals at the Crooked Creek facility
will be aerobically digested. The residuals will be considered stable and therefore suitable for
land application when the following criteria are met:
1. At least seven (7) residuals samples will be collected and analyzed for Fecal Coliform
each monitoring period. The geometric mean of the densities of these samples will be
calculated and will be less than 2,000,000 Colony Forming Units per gram of total dry
solids prior to application.
2. Vector Attraction Reduction will be met through one of the following options: a) volatile
solids reduction of 38% or greater b) biosolids injection or incorporation or c) biosolids
alkaline stabilization.
All residuals will be disposed of in accordance with Residual Land Application Permit No.
WQ0007486.

North Carolina General Statute 133-3
§ 133-3. Specifications to carry competitive items; substitution of materials.
All architects, engineers, designers, or draftsmen, when providing design services, or writing
specifications, directly or indirectly, for materials to be used in any city, county or State work,
shall specify in their plans the required performance and design characteristics of such materials.
However, when it is impossible or impractical to specify the required performance and design
characteristics for such materials, then the architect, engineer, designer or draftsman may use a
brand name specification so long as they cite three or more examples of items of equal design or
equivalent design, which would establish an acceptable range for items of equal or equivalent
design. The specifications shall state clearly that the cited examples are used only to denote the
quality standard of product desired and that they do not restrict bidders to a specific brand, make,
manufacturer or specific name; that they are used only to set forth and convey to bidders the
general style, type, character and quality of product desired; and that equivalent products will be
acceptable. Where it is impossible to specify performance and design characteristics for such
materials and impossible to cite three or more items due to the fact that there are not that many
items of similar or equivalent design in competition, then as many items as are available shall be
cited. On all city, county or State works, the maximum interchangeability and compatibility of
cited items shall be required. The brand of product used on a city, county or State work shall not
limit competitive bidding on future works. Specifications may list one or more preferred brands
as an alternate to the base bid in limited circumstances. Specifications containing a preferred
brand alternate under this section must identify the performance standards that support the
preference. Performance standards for the preference must be approved in advance by the owner
in an open meeting. Any alternate approved by the owner shall be approved only where (i) the
preferred alternate will provide cost savings, maintain or improve the functioning of any process
or system affected by the preferred item or items, or both, and (ii) a justification identifying these
criteria is made available in writing to the public. Substitution of materials, items, or equipment
of equal or equivalent design shall be submitted to the architect or engineer for approval or
disapproval; such approval or disapproval shall be made by the architect or engineer prior to the
opening of bids. The purpose of this statute is to mandate and encourage free and open
competition on public contracts. (1933, c. 66, s. 3; 1951, c. 1104, s. 5; 1993, c. 334, s. 7.1;
