Subject: NPDES Permit # NC0023949
City of Goldsboro
Goldsboro WWTP
Wayne County
In accordance with your application for discharge permit received on March 26, 1993, we are
forwarding herewith the subject State - 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.
The following comments/modifications are made in response to your letter of December 8, 1993,
regarding your draft permit:
• Differences in monitoring frequencies between NPDES permit and pretreatment monitoring
plan - As specified below, several parameters have been dropped from the NPDES permit and
will now be handled solely under the pretreatment monitoring plan.
• Monitoring frequency for lead - The frequency was set at weekly in the draft permit since
that is DEM policy for limited parameters for Class IV treatment facilities. However, after
further evaluation, DEM has decided that a limit is not necessary, and only monthly
monitoring will be required at all permitted flows.
• Monitoring frequency for cyanide and mercury - Both these parameters have been removed
from the NPDES permit and will be handled by the pretreatment long-term monitoring plan.
• Phenols sampling test method - This parameter has been dropped from the permit since
discharge is not into water supply classified waters.
• Monitoring of 1,2-Diphenylhydrazine - This parameter has been dropped from the permit
and will be monitored through pretreatment.
• Compliance demonstration statement for total residual chlorine - Special condition "L" has
been added to address this issue.
• Removal of Annual Pollutant Analysis - This is an intended omission.

G. CHRONIC TOXICITY PASS/FAIL 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 4.0% (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 January, April, July and October. 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
4401 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 retesting(within 30 days of initial monitoring event). Failure to submit
suitable test results will constitute noncompliance with monitoring requirements.
H. CHRONIC TOXICITY PASS/FAIL 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
significantmortality is 6.0% (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

• 4
of this permit during the months of January, April, July and October. 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:

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 constitute noncompliance with monitoring requirements.
I. This permit may be modified, or revoked and reissued to change the effluent limitation on
nutrients for this discharge depending upon the following:
1. The findings of a study by the Division of Environmental Management determine nutrient
control is necessary.
2. Local actions do not successfully reduce the nutrient loading on the receiving waters.
3. The onset of problem conditions in the receiving waters.
J. Reduced instream monitoring has been included in this NPDES permit under the assumption
that the Neuse River Coalition will be formed and approved by the Division of Environmental
Management. If the coalition does not materialize or you choose not to participate, the NPDES
permit may be reopened by administrative letter to include additional instream monitoring
requirements determined to be necessary to adequately characterize the effects of the discharge on
the Neuse River Basin's water quality.
K. In accordance with Chapter 954, Senate Bill 1378, this permit is issued with the stipulation that
there can be no increase in the withdrawal of water from the Little River in excess of the current
pumping capacity. Increases in pumping capacity at the Little River intake are prohibited because
it will cause an interbasin transfer as decribed by the subject bill.

a ` L. When an approved analytical protocol with the appropriate minimum detection level is followed
and a result of non-detectable"or "below quantitation limit" is obtained, the permittee will be
considered to be in compliance with the numerical permit limit for that pollutant.
