Dear Mr. Walters:
Enclosed you will fmd a copy of the Compliance Evaluation Inspection report for
the inspection that was conducted on January 20, 2012, and includes observations that
were made during a tour of the Wastewater Treatment Plant. During the inspection, I
noticed that there was excessive foam present on the surface of the receiving stream for a
distance of approximately 100 meters after Effluent 001. Fortunately, a fallen tree had
stopped the foam from flowing any further downstream (please review the two
photographs, dated 01/20/2012, that are included with this report). In order to dissipate
the foam, the ORC began spraying a continuous mist of water onto the surface of the
receiving stream near the Effluent (please see the enclosed photo). Within forty-eight
hours, all of the foam in the receiving stream, including the foam that had accumulated
near the fallen tree, had disappeared (please see the "After" photographs). It appeared to
me that no foam had flowed into the Lumber River, and that all of the foam had
disappeared from the receiving stream within the POTW property line. The Lumberton
Wastewater Treatment facility was found to be in compliance with NPDES permit
number NC0024571; you and your staff are commended for your continued success.
