Dear Mr. Crosby:
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:
• As the facility is no longer treating contact cooling water, the oil and grease limit and
monitoring requirements have been removed from the permit [See A.(1.)].
• As Outfalls 002, 003 and 004 are no longer in use, authorization to discharge to these
outfalls has been removed from the permit. As a result, Special Condition A.(2.)has also
been removed from the permit.
• As the facility is a Minor facility and no longer discharges complex wastewater, Special
Condition A.(3.)Acute Toxicity Monitoring has been removed from the permit.
• As the facility is no longer treating contact cooling water or process water, Special
Condition A.(4.)Process Water Estimate Outfall 001 has been removed from the permit.
• Because the facility only uses chlorine for disinfection as a backup in the case their UV
system fails, effluent limitation and monitoring requirements for Total Residual Chlorine
apply only when chlorine is used [See A.(1.)].
• 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)
interne application has been added to your NPDES permit [See A.(10.)].
• Parameter codes have been added to the Effluent Limitations and Monitoring Requirements
[ See A.(1.)].
• Regulatory citations have been added to the permit.
