The current Lansing WWTP facility began operation in 1989 and discharges treated 100% domestic wastewater into Big Horse Creek. In December 2010 this segment of Big Horse Creek was reclassified as C, HQW water in the New River Basin. Big Horse Creek was classified as C, Trout, HQW water prior to this reclassification. Untreated domestic wastewater enters the plant headworks where it flows across a manual bar screen and collects in a sump. A composite sampler collects influent samples from the well. Pumps then transfer the wastewater to the aeration basin where blowers provide the aeration. The wastewater then continues to a clarifier module. The liquid continues from the clarifier, through a tablet chlorinator, through a chlorine contact chamber, and through a tablet dechlorinator. The treated wastewater flows through a flow weir. with records effluent flow volumes and is then discharged into Big Horse Creek. An effluent composite sampler collects samples after the meter. When needed the clarifier cones are backwashed and diverted to the aerobic sludge digester. As needed the sludge in the digester is dewatered and hauled by a contractor to Jefferson WWTP for disposal. The Region has noted that this type clarifier system may not be as efficient at maximum permitted flow conditions. There have been some historical problems with undersized and/or poor performing blowers for the aeration basin but they were resolved. Fact Sheet NPDES NC0066028 Page 1 of 3 HISTORY Level B models were conducted for this permitted discharge based on a stream class C and supported secondary treatment standards (designated by the model as water quality limiting) for BOD, TSS, and pH with no additional limits on ammonia or dissolved oxygen. The secondary standard to meet 85% removal of TSS and BOD was also implemented at some point, at or before 2001. Instream and effluent monitoring for fecal coliform was required in 1996. Fecal limits were added in 2001 based on the impact to the receiving stream, compliance was deferred for one year. The instream focal monitoring requirement was removed in 2006 as it'did not apply. The TRC limit was also added in the 2001 permit and compliance was deferred for one year. The installation date of the tablet dechlorination system is unknown. The ammonia toxicity was evaluated in 1988 and the Division detennined no ammonia limits were required but ammonia monitoring was required. No WET testing was required. COMPLIANCE Since 2006 several incidences of unreported and/or missing DMR data did occur but were reconciled with the Regional Office. The fecal coliform limits were exceeded on several occasions in late 2009 and early 2010. No fines were accessed. PERMITTING STRATEGY Data Review DMRs were reviewed for the period of January 2009 to December 2010. DMR data is summarized in Table I below: Table I (* Monthly average data) *Fecal Total *Flow *BOD *TSS Coliform Residual pH NH3-N (MGD) (mg/1) (mg/1) (#//100 ml) Chlorine (S.U.) (mg/1) (mg/1) Average 0.0100 10.14 12.49 202.1 > 20 6.82 3.89 Maximum 0.013 18.0 22.8 1519 > 20 7.6 31.0 Minimum 0.008 5.4 3.8 1 > 20 6.3 0.1 Percent Removal: Based on BOD 92.0% -98.1 %, Based on TSS 88.9% - 97.9% TRC, Fecal Coliform Compliance and Ammonia Toxicity A narrative footnote defining the measurement reporting and compliance protocol for TRC will be added to this permit. Rechecked the IWC % impact on TRC limit, Fecal Coliform limits, and ammonia toxicity monitoring and confirmed existing permit requirements remain valid. Receiving Stream Reclassification The reclassification of the receiving stream removed the Trout designation. Based on WQS the dissolved oxygen minimum standard is reduced to 5.0 mg/l as compared to the Trout classification of 6.0 mg/l. This does not affect any of the facility existing permit requirements. HQW Rules This facility meets existing permitting criteria. However, if this facility ever expands or replaces this treatment works, the ,HQW rules for new/expanding facilities will apply. Fact Sheet NPDES NCO066028 Page 2 of 3 Contacted George Smith, WSR inspector, to discuss the February 2011 inspection report. Pes Mr. Smith there are no issues and he recommends we update the component list narrative. SUMMARY OF PROPOSED CHANGES In keeping with Division policies the following will be incorporated into the permit: • A new TRC footnote narrative will be added to define the reporting and measurement protocols. • The supplemental page treatment component description will be updated to include all significant items. • The receiving stream narratives will be updated to list the stream December 2010 reclassification designation. • The physical facility address will be corrected. • Facility class was corrected to Class /b PROPOSED SCHEDULE FOR PERMIT ISSUANCE Draft Permit to Public Notice: April 27, 2011 Permit Scheduled to Issue: June 2011 NPDES DIVISION CONTACT If you have questions regarding any of the above information or on the attached permit, please contact Ron Berry at (919) 807-6396 or email ron.berry@ncdenr.gov.
