Subject: Draft NPDES Permit Renewal
Permit NC002040 1
Northeast WWTP
Catawba County
Grade IV Biological WPCS
SIC Code 4952
Dear Mr. Wood:
Enclosed with this letter is a copy of the Draft NPDES permit renewal for your facility. Please
review this draft carefully to ensure thorough understanding of the requirements and conditions it
contains. There are several changes from the existing permit, including the following:
• Based on the reasonable potential analysis (RPA) showing no reasonable potential to
violate state water quality standards,the monitoring requirements for Total Cadmium and Total
Silver have been removed from the permit[See A. (1.)].
• Based on NPDES guidance regarding the reduction of monitoring frequencies in NPDES
permits for exceptionally performing facilities,monitoring requirements for BOD5,N-b-N,
Total Suspended Solids and Fecal Coliform have been reduced to twice per week [See A.
(1.)].
• The City of Hickory reported Bis (2-ethylhexyl) phthalate at less than detection of all
samples tested, among which one was at detection level < 50.0 µg/L and another at < 25.0
µg/L in the DMR results).The City's allowable discharge concentration for Bis(2-ethylhexyl)
phthalate is 8.1 µg/L. DWR's laboratory identifies the target Practical Quantification Limit
(PQLs) for Bis (2-ethylhexyl) phthalate as 10.0 µg/L. 15A NCAC 2B .0505 (e) (4) requires
that all test procedures must produce detection and reporting levels that are below the permit
discharge requirements and all data generated must be reported to the approved detection level
or lower reporting level of the procedure. If no approved methods are capable of achieving a
detection level below the permit discharge requirement(or allowable discharge concentration)
the method with the lowest detection level must be used. The City should use sufficiently
sensitive test methods for all pollutants, including when performing Effluent Pollutant Scans.
Quarterly monitoring for Bis(2-ethylhexyl)phthalate has been maintained:
• Instream monitoring parameters have been removed from the Effluent sheet [A. (1.)] and
placed as a separate Special Condition [See A. (2.)].
• Some of the wording has changed in Special Condition A. (3.), Chronic Toxicity Permit
Limit,,please review each paragraph carefully.

• Special Condition A. (4.) has been modified to include the specific three years in which
the Effluent Pollutant Scan shall be performed(2023, 2024,and 2025).
• Federal regulations require electronic submittal of all discharge monitoring reports
(DMRs)and program reports.The requirement to continue reporting discharge monitoring data
electronically using the NC DWR's Electronic Discharge Monitoring Report(eDMR)internet
application has been added to your NPDES permit [See A. (5.)].
• A notation was made concerning the Electronic Reporting Rule — NPDES Electronic
Reporting Rule — Phase 2 Extension. EPA extended the Phase 2 deadline to December 21,
2025 [See A. (5.)].
• Parameter codes have been added to the Effluent Limitations and Monitoring Requirements
and Instream Monitoring Requirements [See A.(1.)and A. (2.),respectively].
• Regulatory citations have been added to the permit.
The NPDES standard conditions(Parts II, III, and IV)that are a part of the permit are not
included in this draft document(cover,map,and Part I).The conditions are the same as in your
current permit except that agency and division names have been updated. The latest version is
available at https://bit.ly/3k5NFaL and can be viewed online or downloaded as a PDF file.
Concurrent with this notification the Division is publishing a notice in a newspaper having
circulation in the general Catawba County area, soliciting public comments on this draft permit.
Please provide any written comments you may have to the following: NCDEQ/DWR, NPDES
Permitting Branch, 1617 Mail Service Center,Raleigh,NC 27699-1617 no later than 30 days after
receipt of this draft permit.
Following the 30-day public comment period,the Division will review all pertinent comments
and take appropriate action prior to issuing a final permit. If you have questions concerning this
draft permit,please call me at(919) 707-3611 or by email at [e-mail].

A. (3.) CHRONIC TOXICITY PERMIT LIMIT (Quarterly) [15A NCAC 02B .0200]
The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant mortality to
Ceriodaphnia dubia at an effluent concentration of 13%.
The permit holder shall perform at a minimum,quarterly monitoring using test procedures outlined in the"North
Carolina Ceriodaphnia Chronic Effluent Bioassay Procedure,"Revised December 2010, or subsequent versions
or "North Carolina Phase II Chronic Whole Effluent Toxicity Test Procedure" (Revised December 2010) or
subsequent versions. 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.
If the test procedure performed as the first test of any single quarter results in a failure or ChV below the
permit limit, then multiple-concentration testing shall be performed at a minimum, in each of the two
following months as described in "North Carolina Phase II Chronic Whole Effluent Toxicity Test
Procedure"(Revised-December 2010)or subsequent versions.
All toxicity testing results required as part of this permit condition will be entered electronically using the
Division's eDMR system for the months in which tests were performed,using the parameter code TGP3B for the
pass/fail results and THP3B for the Chronic Value.Additionally,DWR Form AT-3(original)is to be sent to the
following address:
North Carolina Division of Water Resources
Water Sciences Section/Aquatic Toxicology Branch
1621 Mail Service Center
Raleigh,NC 27699-1621
Or,results can be sent to the email,[e-mail].
Completed Aquatic Toxicity Test Forms shall be filed with the Environmental Sciences Section no later than 30
days after the end of the reporting period for which the report is made.
Test data shall be complete, accurate, include all supporting chemical/physical measurements and all
concentration/response data,and be certified by laboratory supervisor and ORC or approved designate signature.
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,monitoring will be
required during the following month.Assessment of toxicity compliance is based on the toxicity testing quarter,
which is the three month time interval that begins on the first day of the month in which toxicity testing is required
by this permit and continues until the final day of the third month.
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.

Permit NC0020401
If the Permittee monitors any pollutant more frequently than required by this permit,the results of such monitoring
shall be included in the calculation&reporting of the data submitted on the DMR&all AT Form submitted.
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.
