The WTP site is located at the end of SR 2143. 6. Discharge point: Latitude: 350 25' 42" Longitude: 81 ° 53' 17" Attach a USGS Map Extract and indicate treatment plant site and discharge point on map. USGS Quad No.: F 15 NW 7. Site size and expansion area consistent with application: Yes. There is ample area available for expansion, if necessary. 8. Topography (relationship to flood plain included): The WWT facilities that serve the WTP are not be constructed within the flood plain. 9. Location of nearest dwelling: Approx. 500+ feet from the W WTP site. Page Two 10. Receiving stream or affected surface waters: McDowell Creek a. Classification: WS-IV b. River basin and subbasin no.: Catawba 030833 C. Describe receiving stream features and pertinent downstream uses: Flow observed at the proposed point of discharge. The area is generally rural with one significant discharger located - 4.0 miles downstream (NC0036277). The stream channel was 3-5 feet wide X 2-6 inches deep. PART II - DESCRIPTION OF DISCHARGE AND TREATMENT WORKS Phase I' Phase II` Phase III~ 1. a. Volume of Wastewater: 0.700 MGD 2.100 MGD 4.200 MGD `Flow is based on all filters being backwashed in one day. b. What is the current permitted capacity: N/A C. Actual treatment capacity of current facility (current design capacity): N/A d. Date(s) and construction activities allowed by previous ATCs issued in the previous two years: There have been no ATCs issued to this facility in the past two years. e. Description of existing or substantially constructed WWT facilities: The existing WWT facilities consist of a surge/equalization tank followed by a clarifier, a gravity thickener, a flow totalizer, and a sludge storage lagoon. f. Description of proposed WWT facilities: There are no WWT facilities proposed at this time. g. Possible toxic impacts to surface waters: Past DWQ studies have shown WTP effluents to exhibit toxic characteristics. P&E should give some consideration to including a toxicity testing requirement in the renewal of this permit. h. Pretreatment Program (POTWs only): Not Needed. 2. Residual handling and utilization/disposal scheme: Residuals generated at this facility are dewatered on -site and then stored in the storage lagoon until they are land applied by Synagro under the terms and conditions of DWQ permit no. WQ000057. 3. Treatment plant classification: Class I 4. SIC code(s): 4941 Wastewater code(s): 21 MTU code(s): 51003 PART III - OTHER PERTINENT INFORMATION 1. Is this facility being constructed with Construction Grant Funds or are any public monies involved (municipals only)? Public monies were used in the construction of this facility. Page Three 2. Special monitoring or limitations (including toxicity) requests: None with the exception of the toxicity consideration noted in Part II, No. 1(g) above. Important SOC/JOC or Compliance Schedule dates: This facility is neither under an SOC nor is one being considered at this time. 4. Alternative analysis evaluation a. Spray Irrigation: Insufficient area to handle waste flow. b. Connect to regional sewer system: The applicant utilizes a nearby Charlotte - Mecklenburg Utilities (CMU) sewer line as a "backup" to the stream discharge. The WWTP serving the adjacent sewer line has limited capacity, therefore, a discharge to the sewer line is only used when the permittee is cleaning clarifier weirs and troughs when effluent quality would most likely exceed permit limitations. Such being the case, if the WTP is capable of complying with the effluent limitations set forth by the Division, and a total discharge to the sewer line may result in overloading and possibly operational disruption at the WWTP, then a continued discharge to surface waters is the most viable option. C. Subsurface: Insufficient area for the amount of wastewater that is generated. PART IV - EVALUATION AND RECOMMENDATIONS The applicant, CMU, is requesting the renewal of the subject permit to discharge wastewater (filter backwash water) from a WTP located in Mecklenburg County. The WTP was built with an initial treatment capability of 18.0 MGD with an ultimate design flow of 108 MGD (current treatment capability is 25.3 MGD). There have been no changes to the W WT system which serves this WTP since the permit was originally issued nor are any proposed in this renewal. Pending receipt and approval of the draft permit, it is recommended that the permit be renewed as requested.
