SUBJECT: Advance Notice of Renewal Application Requirements
Permit NCOO2O354
Pittsboro WWTP
Dear Permittee:
Your NPDES permit for a municipally owned/operated WWTP expires on April 30, 2006. This notice is being sent to
explain the requirements for your permit renewal application.
You are receiving this advance notice because your facility has a permitted flow at or above 1 MGD, or the subject
facility receives industrial [pretreatment] wastewater. If either of these criteria no longer applies, contact the NPDES
Unit before submitting a renewal application.
Federal (40 CFR 122) and state (15A NCAC 2H.O1O5(e)) regulations require that permit renewal applications be filed at
least 180 days prior to expiration of the current permit. Your renewal application is due to the Division no later than
November 1, 2005. Failure to apply for renewal by the appropriate deadline may result in a civil penalty assessment or
other enforcement activity at the discretion of the Director.
The U.S. EPA revised and expanded the application requirements for municipal permits, effective August 1, 2001. EPA
form 2A is attached to this Notice, and must be used for your permit renewal application. The new application
requirements mandate additional effluent testing:
1. Conduct three Priority Pollutant Analyses (PPAs) and submit results with your renewal application. Collect
samples for the PPAs in conjunction with sampling for your current quarterly toxicity test. The new PPA
requirements differ from previous versions. Each PPA must include:
➢ Analyses for all total recoverable metals listed in Part D of form 2A. This includes metals that are not
normally monitored through your NPDES permit.
➢ Analyses for total phenolic compounds and hardness.
➢ Analyses for all of the volatile organic compounds listed in Part D.
➢ Analyses for all of the acid -extractable compounds listed in Part D.
➢ Analyses for all base -neutral compounds listed in Part D.
➢ Analyses for Total Mercury must be performed using EPA Method 1631.
2. Conduct four toxicity tests for an organism other than Ceriodaphnia and submit results with your renewal
application. The tests should be conducted quarterly, with samples collected on the same day as your
current toxicity test. Call the Aquatic Toxicology Unit at [phone] for guidance in conducting the
additional tests.
These additional analyses must accompany your permit renewal application, or any request for a major permit
modification. The Division cannot draft your permit without the additional data. Any data submitted cannot be over 4
1/2 years old, and must account for seasonal variation (samples cannot be collected during the same season each year

if collected over multiple years). If your permit already contains a requirement for an annual effluent pollutant scan,
additional scans are not required [provided you have conducted at least 3 scans prior to submitting your application].
If any wastewater discharge will occur after the current permit expires, this NPDES permit must be renewed.
Discharge of wastewater without a valid permit would violate Federal and North Carolina law. Unpermitted discharges
of wastewater could result in assessment of civil penalties of up to $25,000 per day.
Use the checklist below to complete your renewal package. The checklist identifies the items you must submit
with the permit renewal application. If all wastewater discharge has ceased at this facility and you wish to rescind this
permit, please contact me. My telephone number, fax number and e-mail address are listed at the bottom of the
previous page.
