Dear Mr. Cummings:
William G. Ross Jr., Secretary
Alan W. Klimek, P.E., Director
Coleen H. Sullins, Deputy Director
Division of Water Quality
Enclosed you will find a copy of the Compliance Biomonitoring Inspection report for the inspection conducted
during the week of February 21, 2005. The inspection included the same objectives as that of a routine Compliance
Evaluation Inspection 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 effluent composite sample at Outfall 001 was collected on February 22 and February 25 the DWQ-Fayetteville
Regional Office for use in a chronic .Ceriodaphnia dubia pass/fail toxicity test. The Division of Water Quality
Aquatic Toxicology Laboratory, located on Reedy Creek Road in Raleigh, completed the aquatic toxicity analysis.
The pass/fail toxicity test, using these samples, resulted in a Pass, indicating that the effluent would not be predicted
to have water quality impacts on the receiving waters. Additionally, on February 22, 2005, the above mentioned
24-hour composite was sampled and analyzed by the Division of Water Quality Chemistry Laboratory (located on
Reedy Creek Road in Raleigh) for the following parameters: Biochemical Oxygen Demand (BOD), Total
Suspended Solids (TSS), Ammonia as nitrogen, Total Kjeldahl Nitrogen, Nitrite plus Nitrate as nitrogen, and Total
Phosphorus. The results of these analyses will be forwarded to you when they are completed. This facility
appeared to be well operated and well maintained.
If you have any questions concerning this report or require clarification on part(s) of this report, please feel
free to contact me at 910/486-1541 ext.712.
