City of Rockingham Wastewater Treatment Plant
Upgrade to Sludge Digester Systems
Richmond County
Dear Mr. Crump:
A letter of request for Authorization to Construct was received May 23, 2005 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 modifications to the
existing 9.0 MGD City of Rockingham Wastewater Treatment Plant, with discharge of treated
wastewater into the Pee Dee River in the Yadkin -Pee Dee Basin.
This authorization results in no increase in design or permitted capacity and is awarded
for the construction of the following specific modifications:
Two new 600,000 gallon aerobic digesters/sludge holding tanks with fine bubble
diffusers, three 150 Hp blowers, replacement of the rotary distributor on the 110-foot
trickling filter, replacement of handrails around the existing primary and secondary
clarification units, and replacement of an existing 48-inch influent mechanical bar
screen at the WWTP Influent Pump Station and Headworks Facility, with associated
piping and electrical work, pursuant to the application received on May 23, 2005, and
in conformity with the project plan, specifications, and other supporting data
subsequently filed and approved by the Department of Environment and Natural
Resources.
This Authorization to Construct is issued in accordance with Part III, Paragraph A of
NPDES Permit No. NC0020427 issued April 16, 2004, and shall be subject to revocation unless
the wastewater treatment facilities are constructed in accordance with the conditions and
limitations specified in Permit No. NC0020427.
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 Fayetteville 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, this Authorization to Construct and the
approved plans and specifications. Mail the Certification to Cecil G. Madden, Jr., P.E.,
Construction Grants & Loans, DWQ / DENR, 1633 Mail Service Center, Raleigh, NC 27699-

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 T 15A: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 T 15A: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.
