Project No. E-SRG-T-00-0091
A letter of request for Authorization to Construct was received October 29, 2001 by the

to be satisfactory. Authorization is hereby granted for the construction of modifications to the
existing 3.2 MGD City of Washington Wastewater Treatment Plant, with discharge of treated
wastewater into the Kennedy Creek in the Tar -Pamlico River Basin.
This authorization results in an increase in design capacity to 3.65 MGD based on the
draft permit limits; however, the permitted capacity has not been increased at this time. Upon
receipt of the revised NPDES Permit, the Owner may request rerating of the facility.
Authorization is awarded for the construction of the following specific modifications:
One new 95-foot diameter secondary clarifier (16-foot sidewall depth), two (2) 152 GPM
scum pumps (one spare), two (2) new 10-foot by 33-foot tertiary deep -bed filter bays, one
(1) new 40-foot by 50-foot metal maintenance building, an 80-GPM vertical turbine reuse
pump with turbidity meter, associated site work, yard piping, electrical work and erosion
control.
This Authorization to Construct is issued in accordance with Part III, Paragraph A of
NPDES Permit No. NC0020648 issued April 7, 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. NC0020648.
Construction activities shall not proceed until the required stormwater permit has been
obtained from the Division. Failure to obtain the required stormwater permit will delay the
commencement of construction.

This Authorization To Construct is issued pursuant to T15A:2H.0219(p) for the
construction of a reclaimed water utilization facility without flow equalization at the site of the
City of Washington WWTP. In the event that non-compliance with any condition or limitation
contained in Permit No. WQ0019179 results from the absence of flow equalization, the City's
NPDES permit may be administratively reopened, and a requirement for the construction of a
flow equalization basin may be incorporated into the permit.
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 Water Quality.
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 Washington Regional Office, telephone number [phone], shall be notified at
least forty-eight (48) hours in advance of operation of the installed facilities so that an on -site
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.
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 NPDES Permit, the Authorization to Construct, and the
approved plans and specifications. Mail the Certification to Cecil G. Madden, Jr., P.E.,
Construction Grants & Loans Section, DWQ / DENR, 1633 Mail Service Center, Raleigh, NC
27699-1633.
Upon classification of the facility by the Certification Commission, the Permittee shall
employ a certified wastewater treatment plant operator to be in responsible charge (ORC) of the
wastewater treatment facilities. The operator must hold a certificate of the type and grade at least
equivalent to or greater than the classification assigned to the wastewater treatment facilities by
the Certification Commission.
The Permittee must also employ a certified back-up operator of the appropriate type and
grade to comply with the conditions of T15A:8G.0202. The ORC of the facility must visit each
Class I facility at least weekly and each Class II, III and IV facility at least daily, excluding
weekends and holidays, must properly manage the facility, must document daily operation and
maintenance of the facility, and must comply with all other conditions of T15A:8G.0202.

A copy of the approved plans and specifications shall be maintained on file by the
Permittee for the life of the facility.
During the construction of the proposed additions/modifications, the permittee shall
continue to properly maintain and operate the existing wastewater treatment facilities at all times,
and in such a manner as necessary to comply with the effluent limits specified in the NPDES
Permit.
You are reminded that it is mandatory for the project to be constructed in accordance with
the North Carolina Sedimentation Pollution Control Act, and, when applicable, the North
Carolina Dam Safety Act. In addition, the specifications must clearly state what the contractor's
responsibilities shall be in complying with these Acts.
Failure to abide by the requirements contained in this Authorization to Construct may
subject the Permittee to an enforcement action by the Division of Water Quality in accordance
with North Carolina General Statute 143-215.6A to 143-215.6C.
The issuance of this Authorization to Construct does not preclude the Permittee from
complying with any and all statutes, rules, regulations, or ordinances which may be imposed by
other government agencies (local, state, and federal) which have jurisdiction.
One (1) set of approved plans and specifications is being forwarded to you. If you have
any questions or need additional information, please contact Cecil G. Madden, Jr., P.E. at
