Subject: Draft NPDES Permit Renewal
Permit NC0026751
Windsor WWTP
Bertie County
Grade III Biological WPCS
SIC Code 4952
Dear Mr. Castelloe:
Enclosed with this letter is a copy of the Draft NPDES permit renewal for your facility. Please
review this draft carefully to ensure a thorough understanding of the requirements and conditions
it contains. There are several changes from the existing permit, including the following:
• The monthly average limit for copper was adjusted from 13.8 mg/1 to 11.9 mg/1 and the
daily maximum limit from 19.4 mg/1 to 16.5 mg/1 as the standard for copper is calculated
based on average effluent hardness.
• The monitoring frequency for BOD and TSS was modified from 3 times per week to 2
times per week in accordance with the Division's Guidance for Reduction in Monitoring
Frequency for Exceptionally Performing Facilities.The monitoring frequency for ammonia
and fecal coliform was modified from weekly to 2 times per week. Although the current
permit required weekly monitoring, according to 15 NCAC 02B.0508, Class III domestic
wastewater facilities should monitor these parameters at a minimum frequency of 3 times
per week. Data was evaluated and the monitoring frequency was adjusted to the minimum
monitoring frequency under the Reduction in Monitoring Frequency Guidance which is 2
times per week.
• Special Condition A. (3.), Chronic Toxicity Permit Limit, was updated to include an email
for reporting results.
• Special Condition A. (3.)was updated to include parameter codes.
• Special Condition A. (5.) Electronic Reporting has been updated to agree with the
Electronic Reporting Rule—NPDES Electronic Reporting Rule—Phase 2 Extension. EPA
extended the Phase 2 deadline to December 21, 2025.
• Special Condition A (4.) PFAS Monitoring Requirement was added to the permit as per
the North Carolina PFAS Action Strategy. Twice per year monitoring takes effect the first
full calendar quarter following 6 months after EPA publishes the final PFAS method.

A. (2.)CHRONIC TOXICITY PERMIT LIMIT(QUARTERLY)
[15A NCAC 02B .0200] [15A NCAC 02B .0500 et seq]
The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant
mortality to Ceriodaphnia dubia at an effluent concentration of 90%.
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

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 fmal 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.
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
