Footnotes:
1. The permittee shall submit discharge monitoring reports electronically using the NC DWR's eDMR
application system [see Section A. (4)].
2. Limit and monitor only if the facility adds chlorine or chlorine derivatives to water that is eventually
discharged. The Division shall consider all effluent TRC values reported below 50 µg/L to be in compliance
with the permit. However,the Permittee shall continue to record and submit all values reported by a North
Carolina certified laboratory(including field certified),even if these values fall below 50 pg/L.
3. Effluent hardness sampling should be performed in conjunction with testing for hardness dependent metals
(cadmium, copper, lead, nickel, silver, and zinc).
4. The Permittee shall sample instream hardness, upstream of the facility's discharge. The sample shall be
representative of the hardness in the receiving stream. If the Permittee is a member of the Monitoring
Coalition Program, sampling for instream hardness may be waived as long as the Monitoring coalition agrees
to sample hardness at the nearest upstream location,at a minimum frequency of quarterly, and the Permittee
has obtained approval from DWR-NPDES Permitting Unit that the upstream station being monitored by the
Coalition is representative of the receiving stream for this discharge.The Permittee is responsible for
submitting instream hardness test results with its permit renewal application package. If Coalition
membership is cancelled or the Coalition terminates instream hardness sampling at the approved station,the
Page 3 of 8

Permit NC0075701
Permittee will immediately notify the Division and resume sampling for instream hardness,upstream of its
discharge.
5. Whole Effluent Toxicity testing of Ceriodaphnia dubia shall be performed as a 7 day pass/fail test at 90%
effluent concentration during January, April, July, and October [See Sections A. (2) and A. (3)].
All samples collected should be from a representative discharge event.
There shall be no discharge of floating solids or visible foam in other than trace amounts.

A. (2) CHRONIC TOXICITY PASS/FAIL MONITORING ONLY(QUARTERLY)
[15A NCAC 02B .0500 et seq.]
The permittee shall conduct quarterly chronic toxicity tests using test procedures outlined in the"North Carolina
Ceriodaphnia Chronic Effluent Bioassay Procedure,"Revised December 2010,or subsequent versions.
The effluent concentration defined as treatment two in the procedure document is 90 %. The testing shall be
performed as a Ceriodaphnia dubia 7-day pass/fail test. The tests will be performed during the months of
January,April,July,and October. These months signify the first month of each three month toxicity testing
quarter assigned to the facility. Effluent sampling for this testing must be obtained during representative effluent
discharge and 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,DWR Form AT-1 (original)is to be sent to the following address:
Attention: North Carolina Division of Water Resources
Water Sciences Section/Aquatic Toxicology Branch
1621 Mail Service Center
Raleigh,NC 27699-1621

the end of the reporting period for which the report is made.
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 there be no discharge of flow from the facility during a month in which toxicity monitoring is required,
the permittee will complete the information located at the top of the aquatic toxicity(AT)test form indicating the
facility name,permit number,pipe number, county, and the month/year of the report with the notation of"No
Flow"in the comment area of the form. The report shall be submitted to the Water Sciences Section at the address
cited above.
Should the permittee fail to monitor during a month in which toxicity monitoring is required,then monthly
monitoring will begin immediately.Upon submission of a valid test,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 Water
Resources 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,minimum control organism reproduction, and appropriate environmental controls, shall constitute an
invalid test and will require immediate follow-up testing to be completed no later than the last day of the month
following the month of the initial monitoring.

1. Reporting Requirements [Supersedes Section 1). (2.) and Section E. (5.) (a)l
The permittee shall report discharge monitoring data electronically using the NC DWR's Electronic Discharge
Monitoring Report(eDMR)internet application.
Monitoring results obtained during the previous month(s)shall be summarized for each month and submitted
electronically using eDMR. The eDMR system allows permitted facilities to enter monitoring data and submit
DMRs electronically using the internes. Until such time that the state's eDMR application is compliant with
EPA's Cross-Media Electronic Reporting Regulation(CROMERR),permittees will be required to submit all
discharge monitoring data to the state electronically using eDMR and will be required to complete the eDMR
submission by printing, signing,and submitting one signed original and a copy of the computer printed eDMR to
the following address:
NC DEQ/Division of Water Resources/Water Quality Permitting Section
ATTENTION: Central Files
1617 Mail Service Center
Raleigh,North Carolina 27699-1617
If a permittee is unable to use the eDMR system due to a demonstrated hardship or due to the facility being
physically located in an area where less than 10 percent of the households have broadband access,then a
temporary waiver from the NPDES electronic reporting requirements may be granted and discharge monitoring
data may be submitted on paper DMR forms(MR 1, 1.1,2, 3)or alternative forms approved by the Director.
Duplicate signed copies shall be submitted to the mailing address above. See"How to Request a Waiver from
Electronic Reporting"section below.
Regardless of the submission method,the first DMR is due on the last day of the month following the issuance of

Electronic submissions must start by the dates listed in the"Reporting Requirements"section above.
3. How to Request a Waiver from Electronic Reporting
The permittee may seek a temporary electronic reporting waiver from the Division. To obtain an electronic
reporting waiver,a permittee must first submit an electronic reporting waiver request to the Division. Requests
for temporary electronic reporting waivers must be submitted in writing to the Division for written approval at
least sixty(60)days prior to the date the facility would be required under this permit to begin submitting
monitoring data and reports. The duration of a temporary waiver shall not exceed 5 years and shall thereupon
expire. At such time,monitoring data and reports shall be submitted electronically to the Division unless the
permittee re-applies for and is granted a new temporary electronic reporting waiver by the Division. Approved
electronic reporting waivers are not transferrable. Only permittees with an approved reporting waiver request
may submit monitoring data and reports on paper to the Division for the period that the approved reporting waiver
request is effective.
Information on eDMR and the application for a temporary electronic reporting waiver are found on the following
web page:
