Subject: NPDES Permit Issuance
Permit No. NCO021181
Belmont WWTP
Gaston County
Dear Ms. Standafer:
In accordance with the application for a discharge permit received on February 15, 1996, the Division is
forwarding herewith the subject NPDES permit. This permit is issued pursuant to the requirements of North
Carolina General Statute 143-215.1 and the Memorandum of Agreement between North Carolina and the US
Environmental Protection Agency dated December 6,1983.
Please be aware that limits for Total Phosphorus (TP) and Total Nitrogen (TN) have been eliminated
from this permit due to changes made in the Lake Wylie Management Plan. However, upon expansion of the
facility, new limits for TP and TN will.take effect as stipulated in the Catawba Basin Wide Management
Strategy and as outlined in Part III, Special Condition H of this permit.
Please note that instream sampling must be conducted at the proper locations as designated on the permit
effluent sheets. Upstream samples are to be collected at US Highway 74. Downstream samples are to be
collected one mile below the point of discharge.
If any parts,measurement frequencies or sampling requirements contained in this permit are unacceptable
to you, you have the right to an adjudicatory hearing upon written request within thirty (30) days following
receipt of this letter. This request must be in the form of a written petition,conforming to Chapter 150B of the
North Carolina General Statutes, and filed with the Office of Administrative Hearings, Post Office Drawer
27447, Raleigh, North Carolina 27611-7447. Unless such demand is made, this decision shall be final and
binding.
Please take notice this permit is not transferable. Part II, EA. addresses the requirements to be followed
in case of change in ownership or control of this discharge. This permit does not affect the legal requirements to
obtain other permits which may be required by the Division of Water Quality or permits required by the
Division of Land Resources, Coastal Area Management Act or any other Federal or Local governmental permit
that may be required. if you have any questions concerning this permit, please contact Steve Pellei at
telephone number(919)733-5083,extension 516.

During the period beginning on the effective date of the permit and lasting until expiration, the Permitlee is authorized to discharge from
oulfall(s) serial number 001. Such discharges shall bu limited and monitored by the pertnitlee as specified below:

Part III Permit No. NC0021181
G. CHRONIC TOXICITY PASS/FAII.PERMIT LIMIT(QRTRLY)
The effluent discharge shall at no time exhibit chronic toxicity using test procedures outlined in:
1.) The North Carolina Ceriodaphnia chronic effluent bioassay procedure (North Carolina Chronic
Bioassay Procedure - Revised *September 1989) or subsequent versions.
The effluent concentration at which there may be no observable inhibition of reproduction or
significant mortality is 8% (defined as treatment two in the North Carolina procedure document).
The permit holder shall perform quarterly monitoring using this procedure to establish compliance
with the permit condition. The first test will be performed after thirty days from the effective date
of this permit during the months of February, May, August and November. Effluent sampling for
this testing shall be performed at the NPDES permitted final effluent discharge below all treatment
processes.
All toxicity testing results required as part of this permit condition will be entered on the Effluent
Discharge Monitoring Form (MR-1) for the month in which it was performed, using the parameter
code TGP3B. Additionally, DEM Form AT-1 (original) is to be sent to the following address:
Attention:
Environmental Sciences Branch
North Carolina Division of
Environmental Management
4.401 Reedy Creek Road
Raleigh, N.C. 27607
Test data shall be complete and accurate and include all supporting chemical/physical measurements
performed in association with the toxicity tests, as well as all dose/response data. Total residual
chlorine of the effluent toxicity sample must be measured and reported if chlorine is employed for
disinfection of the waste stream.
Should any single quarterly monitoring indicate a failure to meet specified limits, then monthly
monitoring will begin immediately until such time that a single test is passed. Upon passing, this
monthly test requirement will revert to quarterly in the months specified above.
Should any test data from this monitoring requirement or tests performed by the North Carolina
Division of Environmental Management indicate potential impacts to the receiving stream, this
permit may be re-opened and modified to include alternate monitoring requirements or limits.
NOTE: Failure to achieve test conditions as specified in the cited document, such as minimum
control organism survival and appropriate environmental controls, shall constitute an invalid test
and will require immediate retestin g(wi thin 30 days of initial monitoring event). Failure to submit
suitable test results will constitute noncompliance with monitoring requirements.
H. Upon expansion Total Phosphorous and Total Nitroe will be limited to 1.0 mg/I TP and 6
mg/l TN (summer only) in accordance with the Lake'Zoe Management Plan.

PART IV
ANNUAL ADMINISTERING AND COMPLIANCE MONITORING FEE
REQUIREMENTS
A. The permittee must pay the annual administering and compliance monitoring fee
within 30 (thirty) days after being billed by the Division. Failure to pay the fee in a
timely manner in accordance with 15A NCAC 2H .0105(b)(4) may cause this Division to
initiate action to revoke the permit.

Test data shall be complete and accurate and include all supporting chemical/physical measurements
performed in association with the toxicity tests, as well as all dose/response data. Total residual chlorine
of the effluent toxicity sample must be measured and reported if chlorine is employed for disinfection of

Should any single quarterly monitoring indicate a failure to meet specked limits, then monthly
monitoring will begin immediately until such time that a single test is passed. Upon passing, this
monthly test requirement will revert to quarterly in the months specified above.
Should any test data from this monitoring requirement or tests performed by the North Carolina Division
of Environmental Management indicate potential impacts to the receiving stream, this permit may be re-
opened and modified to include alternate monitoring requirements or limits.
NOTE: Failure to achieve test conditions as specified in the cited document, such as minimum control
organism survival and appropriate environmental controls, shall constitute an invalid test and will require
immediate retesting(within 30 days of initial monitoring event). Failure to submit suitable test results will
