Dear Mr Ellis:
Governor
DONALD R. VAN DER VAART
Secretary
S. JAY ZIMMERMAN
Director
Enclosed please find a copy of the Bioassay Compliance, inspection'form from the inspection conducted
on 2/9/2016 and 2/11/2016. The Bioassay Compliance Inspection was conducted by_ Mark Brantley,
Environmental Program Consultant, of the Fayetteville Regional Office. The facility was found to be in
Compliance with permit NC0020656. The cooperation of Mr. Ricky Odum was greatly appreciated. As a
reminder, preservation of the Waters of 'the State can only be achieved through consistent NPDES
Permit compliance.
Comments
• Facility was clean and neat in appearance at the time of the inspection.
• A Whole Effluent Toxicity test was collected at Outfall 001 from the Laurinburg Leith Creek
WWTP 24-hour composite equipment on February 9 and 11, 2016 for use in a chronic
Ceriodaphnia Dubia pass/fail toxicity test. These samples we're sent to the Division of Water
Resources (AT) Laboratory (located on Reedy Creek Road in Raleigh). Results have not been
received from this:test at the time this letter was written. Results will follow at a later time.
• The effluent flow meter was out of service at the time of the inspection but it has been repaired
and placed back into service.
• . The automatic bar screen has been out of service for several weeks but Mr. Odum stated parts
had, been ordered. The manufacturer stated the repair parts were at least 6 weeks out.
Currently facility staff is using the manual barscreen.
• Number 2 recirculation pump has been out of service since January 2016 and the city has been
told it is not repairable. A new one will be ordered. Currently the WWTP has 2 other
recirculation pumps that can keep up with demand.
