Subject: Draft NPDES Permit Renewal
Permit NC0040797
Henry Fork WWTP
Catawba County
Facility Class IV
SIC Code 4952
Dear Mr. Greer:
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 followmg:
• Removed effluent and mstream monitoring requirements for color after reviewing monitoring data
and recommendation of the Mooresville Regional Office. The special condition on Color
Permitting Requirements has been removed from the permit and a new special condition to reopen
the permit has been added if water quality standards for color are violated.
• Removed effluent limitations and momtonng requirements for total chromium, cyanide and total
nickel based on results of the Reasonable Potential Analysis (RPA). The permittee shall continue
to monitor these metals under the pretreatment program.
• Removed effluent limitations and monitoring requirements for mercury as per EPA approved
statewide mercury TMDL.The permittee shall continue to monitor mercury under the pretreatment
program.
• Removed monitoring requirements for total silver based on results of RPA. The facility will
continue to report total silver at its practical quantitation limit (PQL) of 1 tg/L under the
pretreatment program.
• Removed monitoring requirements for chloride based on results of RPA.

• Removed instream monitoring requirements for fecal coliform as receiving stream is not impaired
for fecal coliform.
• Updated monthly average and daily maximum permit limitations for Bis (2-ethylhexyl) phthalate
from 29 µg/L to 28.5 µg/L as per results of RPA.
• Added monthly average and daily maximum limits for total copper and changed momtonng
requirements from quarterly to monthly as per results of RPA.
• Added quarterly monitoring for total cadmium according to the Division's guidance for water
quality standards for hardness dependent dissolved metals. Cadmium is currently reported at the
levels less than 1 µg/1 but the permittee is required to report results at the Practical Quantification
Level(PQL)i.e. 0.5 µg/l.
• Sampling frequency for effluent pollutant scan has been modified to three times during the permit
cycle Special condition A.(3)Effluent Pollutant Scan has been modified to include narrative for
additional toxicity test requirements for permit renewal.
• Added Mercury Minimization Plan(MMP)to the permit according to the Statewide Mercury
TMDL.The City of Hickory will be responsible for implementing this plan.
• The NC 2007-2014 Water Quality Standard(WQS)Tnenmal Review was approved by the NC
Environmental Management Commission(EMC)on November 13, 2014.The US EPA
subsequently approved the WQS revisions on April 6,2016 with some exceptions The NC
Division of Water Resources NPDES Permitting Unit is required to implement the new dissolved
metal standards in all permits public noticed after April 6, 2016
The new standards for most metals include acute standards. Further,the freshwater standards for
several metals are expressed as the dissolved form of the metals, and seven metals have hardness-
dependent equations.As a result,the NPDES Permitting Unit will need site-specific effluent
hardness data and mstream hardness data,upstream of the discharge, for each facility monitoring
these metals in order to calculate permit limitations. Effluent and upstream hardness have been
added to this permit at a quarterly monitoring frequency. Hardness sampling should be performed
in conjunction with testing for metals.
• Federal regulations require electronic submittal of all discharge monitoring reports(DMRs)and
program reports.The final NPDES Electronic Reporting Rule was adopted and became effective
on December 21,2015.The requirement to begm reporting discharge monitoring data
electronically using the NC DWR's Electromc Discharge Monitoring Report(eDMR) mternet
application has been added to this permit. [See Special Condition A(9)]
