NOV 3 0 1999 State of North Carolina Department of Environment and Natural Resources Division of Water Quality James B. Hunt, Jr., Governor Bill Holman, Secretary Kerr T. Stevens, Director J IDH 99 MEMORANDUMTo: Britt Setzer .R gRANC DENR / / Regi3z��-�rrgineer Mooresville Regional Office From: Michael J.

RESPONSE: (Check one) RrConcur with the issuance of this permit provided the facility is operated and maintained properly, the stated effluent limits are met prior to discharge, and the discharge does not contravene the designated water quality standards.

One hundred percent of the influent is domestic waste. The Greater Badin WWTP is currently operating at greater than 80% of the design capacity. Stanly County Office of Utilities suspects that the elevated flow is caused by I/I and has initiated rehabilitation of the sewer system. The sewer rehabilitation work was due to be completed late September, however, the project is behind schedule and Greater Badin has been granted an extension to the SOC. The Greater Badin WWTP discharges into Little Mountain Creek, which is listed as partially supporting its designated uses according to the 1998 Yadkin -Pee Dee River Basinwide Water Quality Plan. The `partially supporting' rating was implemented due to poor benthic macroinvertebrate monitoring data. According to the Planning and Assessment Unit the reason for the poor water quality in Little Mountain Creek has not been determined. At this time there is no current or pending TMDL. Little Mountain Creek is classified as WS-IV waters from 0.5 miles upstream of Stanly County SR 1545 to Mountain Creek TOXICITY TESTING: Current Requirement: NH-3 limits were implemented based on toxicity results. The winter ammonia limit in the current permit was calculated using the 30Q2 flow. Recommended Requirement: Recalculation of the winter ammonia toxicity limit using the 7Q10 flow indicates that an ammonia limit of 3.0 mg/l is appropriate. COMPLIANCE SUMMARY: Several non -compliant DMRs have been submitted primarily due to the ongoing sewer rehabilitation work DMR data suggest that the facility is currently operating below 5 mg/I of BOD (monthly average) with a permitted limit of 20 mg/I. INSTREAM MONITORING: Instream monitoring has been waived because of membership in the Yadkin -Pee Dee River Basin Association. Greater Badin Wastewater Treatment Plant Fact Sheet NPDES Renewal D_. . 1 PROPOSED CHANGES: Increase the winter ammonia limit from 2.7 mg/1 to 3.0 mg/l. The 2.7 limit was based on the 30Q2 flow not the winter 7Q10, therefore the ammonia limit was recalculated using the winter 7Q10 flow. Instream fecal coliform monitoring has been removed from the permit. Though the stream is on the 303(d) . list the basin plan does not indicate that this impairment is due to fecal coliform. According to the instream monitoring policy if the stream is not impaired for fecal coliform then instream fecal coliform monitoring may be removed. Instream conductivity monitoring will be removed from the permit per the 5/12/99 Instream Monitoring Policy. Total N and total P monitoring will be changed from monthly to quarterly. Per -a 12/7/98 memo from Steve _ Pellei dischargers in subbasin 030708 in the Yadkin Pee -Dee River Basin -having a permitted flow -between 0.05 MGD and 1.0 required quarterly nutrient monitoring. BOD, TSS, DO, and Fecal (Effluent) monitoring frequencies has been changed to 3/week. According to the new rating system this facility is rated as a class III facility and increased monitoring is required. Likewise, instream monitoring of temperature has been increased to 3/week and monitoring of effluent temperature has been increased to daily. Stanly County Office of Utilities is currently attempting to address the flow problems associated with this facility. If Greater Badin wishes to request expansion of their flow then justification for the expansion is required. If the expansion were granted, the expanded discharge would be subject to advanced tertiary limits. Note, I/I is not considered justification for expansion.

River Basin and Subbasin No.: Yadkin 03-07-08 C. Describe receiving stream features and pertinent downstream uses: The receiving stream is 6-8 feet wide and 2-6 inches deep. The channel bed is composed en 'rel-y-o slate rock (no sand or silt areas). An ALCOA plant discharges cooling water upstream of the site in accordance-with-permitNC000-4308.

Description of existing or substantially co -eructed WWT facilities: The existing WWT facilities consist of a manually cleaned bar screen, an influent pump station, an orbital aeration basin (oxidation ditch), an aerobic sludge digester (located in the center of the oxidation ditch), dual final clarifiers, dual chlorine contact chambers with gaseous disinfection, SO, dechlorination, cascade post aeration, four sludge drying beds and stand-by power. f. Description of proposed WWT facilities: No modifications to the WWTP are proposed at this time. The sewer collection system is being rehabilitated. If storm water flow to the plant is not reduced after the sewer rehabilitation work is completed, modifications and/or additions to the WWTP may be necessary. g. Possible toxic impacts to surface waters: Chlorine is added to the waste stream; however, dechlorination is utilized and the facility has a chlorine limit. h. Pretreatment Program (POTWs only): Not needed. The facility only receives domestic waste. 2. Residual handling and utilization/disposal scheme: a.

There have been no additions or modifications to the WWTP during this permit cycle. The collection system serving the plant continues to experience excessive I&I after rainfall. The permittee entered into an SOC with the Division during this permit cycle. The SOC required extensive testing and repair to the collection system. All activities associated with the SOC were completed by December 1995. While I&I flows were slightly reduced, effluent from the plant still exceeds the permitted Greater Badin W WTP MRO Staff Report — (NPDES Permit Renewal) Page 4 of 4 limit on a frequent basis. In addition, the effluent flow has exceeded 80% of the design flow during the previous two calendar years. The Division sent a letter to the permittee which described the flow evaluation/analysis report required upon exceeding the 80% criteria (in accordance with 2H .0223). The permittee still believes that most of the flow problems can be reduced with further sewer rehabilitation rather than plant upgrades or expansion. The permittee has arranged for additional rehabilitation work to be performed on the collection system. The additional repair work is scheduled to begin on May 6, 1999. The work should be completed within 120 days of start-up. If flow levels remain elevated after the additional repair work, the permittee stated that it will prepare the report required in accordance with 2H .0223. Despite the on -going I&I issues, the WWTP has continued to treat the wastewater received at the plant within substantial compliance of the existing permit (for parameters other than flow). It is recommended that the NPDES permit be renewed as requested. .n►r/ t a . 1 Report Preparer Dite Water Quality Re ' nal Supervisor D to h:\\npdes\gbadin. doc •:.�1` .
