Klimek, P.E., Director Division of Water Quality November 20, 2006 Paul Davis Executive Director Laurinburg-Maxton Airport Conunission (LMAC) P.O. Box 31 Laurinburg, NC 28352 Subject: Compliance Biomonitoring Inspection Laurinburg-Maxton Airport Commission (LMAC) NPDES Permit No. NC0044725 Scotland County Dear Mr. Davis: . Enclosed you will find a copy of the Compliance Biomonitoring Inspection report for the inspection conducted the week of October 30, 2006. The inspection included the same objectives as that of a routine Compliance Evaluation Inspection (conducted on October 31, 2006) plus an Aquatic Toxicity (AT) test to evaluate the biological effect of the facility's discharge on test organisms. As part of the inspection a tour of the Wastewater Treatment Plant was conducted. All observations and recommendations are in Part D: Summary of Findings/Comments of this inspection report.. A 24-hour 001 effluent composite sample was collected at your facility by DWQ-FRO on October 31 and on November 3. The DWQ aquatic toxicity samples were sent to the Division of Water Quality Aquatic Toxicology Laboratory (located on Reedy Creek Road in Raleigh) and resulted in a "Pass". The test results for the whole effluent toxicity samples indicated that the effluent would not be predicted to have water quality impacts on the receiving water. Additionally, on October 31, the 24-hour Outfall 001 effluent was sampled for the following parameters: Biochemical Oxygen Demand (BOD), Ammonia as nitrogen, Total Kjeldahl Nitrogen, Nitrite plus Nitrate as nitrogen, Total Phosphorus, Cobalt, and Sodium. The laboratory results of the pending chemistry analyses will be forwarded to you when they are completed by the Division of Water Quality Chemistry Laboratory, located on Reedy Creek Road in Raleigh. If you have any questions or cominents concerning this report, please feel free to 'contact Dale Lopez at (910) 433-3312.

Plans are to fix the starter soon. The generator was routinely tested under load once per quarter, and each of the other months the generator was tested for one hour without being placed under load. The generator was capable of supplying electrical power for the entire POTW. On the day of the inspection, the facility appeared to be in compliance with the requirements of the NPDES permit.
