During the last permit renewal, Bis (2-ethylhexyl) plithalate was added to our permit testing requirements. Staff identified the tubing used to collect past priority pollutant samples inadvertently contaminated the samples. There was a warning label on the tubing box that stated the tubing contained Bis (2-ethylhexyl) plithalate. After identifying this interference, the City started using tubing that does not contain this contaminant and did not have any detects during most recent testing. Therefore, the City would request that Bis (2-ethylhexyl) plithalate be removed from the new permit. Please do not hesitate to contact me at (910) 892-2948 if you need further information in order to complete your review.
