This type of inspection consists of two basic parts: an in -office file review and an on -site inspection of the treatment facility. The attached EPA inspection form details the areas that were evaluated during this inspection. The inspection of the facility was satisfactory; however, the contents of the chlorine contact tank were turbid. Mr. Overby said that he was having the chlorine contact tank pumped out. If you have any questions regarding the inspection or this report, please contact Gary Hudson or me at (336) 776-9800 or by email at gary.hudson(a).ncdenr.gov or Ion. snider(c_ncdenr.gov.
