We are working with CMUD in Charlotte to determine if we can discontinue a GroundWater Pre-treatment System. Based on criteria stipulated by the city in 2007, 1 a City of Charlotte Wastewater Discharge Permit was not required. CMUD has asked that we confirm if a NPDES Permit was issued by NCDENR. The facility is located at 100 North College Street and is a Bank of America facility managed by Lincoln Harris. I searched the on-line database but did not see any matches. Would you be able to confirm if a NPDES Permit was issued for this site. THANKS - Dawn Dawn C.

Topography (relationship to flood plain included): The site is relatively flat and well removed from any flood plain. 9. Location of nearest dwelling: Approx. 1000+ feet from the site. Page Two 10. Receiving stream or affected surface waters: UT to Sugar Creek a. Classification: C b. River Basin and Subbasin No.: Catawba 030834 c. Describe receiving stream features and pertinent downstream uses: The receiving stream is a headwaters channel that originates near the center of Charlotte. The channel was dry at the time of the site investigation. The stream passes through a heavily developed portion of Charlotte prior to its confluence with the main segment of Sugar Creek. There may be other downstream dischargers on this segment with similar de -watering facilities. The main segment of Sugar Creek is listed as a 303(d) impaired stream. PART II - DESCRIPTION OF DISCHARGE AND TREATMENT WORKS a. Volume of wastewater: 0.030 MGD (Design Capacity) b. What is the current permitted capacity: N/A (new facility) c. Actual treatment capacity of current facility (current design capacity): There are no existing treatment facilities d, Date(s) and construction activities allowed by previous ATCs issued in the previous two years: N/A e. Description of existing or substantially constructed WWT facilities: There are no existing WWT facilities. g. Description of proposed WWT facilities: The applicant has no submitted a proposal for any proposed WWT facilities at this time. Possible toxic impacts to surface waters: Toxic impacts are unknown at this time. Toxicity monitoring is proposed in the draft peiinit. h. Pretreatment Program (POTWs only): N/A 2. Residual handling and utilization/disposal scheme: Residuals generation is not expected from this discharge. Treatment plant classification: Unknown at this time pending the need to install wastewater treatment. 4. SIC Code(s): 9999 Wastewater Code(s): 66 MTU Code(s): N/A PART III - OTHER PERTINENT INFORMATION Is this facility being constructed with Construction Grant Funds or are any public monies involved (municipals only)? No public monies will be used in the construction of this Page Three 2. Special monitoring or limitations (including toxicity) requests: The Central Office is recommending the monitoring for carbon tetrachloride and chloroform. based on analytical testing performed in February 2007. This Office concurs with this recommendation. Important SOC/JOC or Compliance Schedule dates: N/A 4. Alternative analysis evaluation a. Spray Irrigation: There is insufficient area on the site to construct a spray irrigation treatment system. b. Connect to regional sewer system: The local POTW has refused the applicant's request to discharge this waste stream into the sewer collection system. c. Subsurface: There is insufficient area onsite to install a subsurface disposal system. d. Other disposal options: None that we are aware. PART IV - EVALUATION AND RECOMMENDATIONS The applicant has requested approval to discharge contaminated GW from a site near the center of Charlotte to a UT to Sugar Creek in Mecklenburg County. The GW contamination originates from past uses of the site, which included a dry cleaning facility and a gas station. The primary contaminants are solvents and volatile organic compounds. There appears to be no other alternative to a discharge to surface waters at this location. The discharge will enter the City of Charlotte's storm water drainage system and travel for a distance of several hundred feet prior to reaching the receiving stream. The applicant did not propose treatment of the contaminated GW prior to discharge, however, limits contained in the draft permit may necessitate the installation of some type treatment facilities in order to comply with current WQ standards. Pending a final technical review of this request by the NPDES Unit, it is recommended that an NPDES Permit be issued.

(2) CHRONIC TOXICITY PERMIT LIMIT (QRTRLY) The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant mortality to Ceriodaphnia dubia at an effluent concentration of 90%. The permit holder shall perform at a minimum, quarterly monitoring using test procedures outlined in the "North Carolina Ceriodaphnia Chronic Effluent Bioassay Procedure," Revised February 1998, or subsequent versions or "North Carolina Phase Q Chronic Whole Effluent Toxicity Test Procedure" (Revised -February 1998) or subsequent versions. The tests will be performed during the months of January, April, July and October. Effluent sampling for this testing shall be performed at the NPDES permitted final effluent discharge below all treatment processes. If the test procedure performed as the first test of any single quarter results in a failure or ChV below the permit limit, then multiple -concentration testing shall be performed at a minimum, in each of the two following months as described in "North Carolina Phase II Chronic Whole Effluent Toxicity Test Procedure" (Revised -February 1998) or subsequent versions. The chronic value for multiple concentration tests will be determined using the geometric mean of the highest concentration having no detectable impairment of reproduction or survival and the lowest concentration that does have a detectable impairment of reproduction or survival. The definition of "detectable impairment," collection methods, exposure regimes, and further statistical methods are specified in the "North Carolina Phase II Chronic Whole Effluent Toxicity Test Procedure" (Revised -February 1998) or subsequent versions. All toxicity testing results required as part of this permit condition will be entered on the Effluent Discharge Monitoring Form (MR-1) for the months in which tests were performed, using the parameter code TGP3B for the pass/fail results and THP3B for the Chronic Value. Additionally, DWQ Form AT-3 (original) is to be sent to the following address: Attention: North Carolina Division of Water Quali Environmental Sciences Section 1621 Mail Service Center Raleigh, North Carolina 27699-1621 Completed Aquatic Toxicity Test Forms shall be filed with the Environmental Sciences Section no later than 30 days after the end of the reporting period for which the report is made. Test data shall be complete, accurate, include all supporting chemical/physical measurements and all concentration/response data, and be certified by laboratory supervisor and ORC or approved designate signature. Total residual chlorine of the effluent toxicity sample must be measured and reported if chlorine is employed for disinfection of the waste stream. Should there be no discharge of flow from the facility during a month in which toxicity monitoring is required, the permittee will complete the information located at the top of the aquatic toxicity (AT) test form indicating the facility name, permit number, pipe number, county, and the month/year of the report with the notation of "No Flow" in the comment area of the form. The report shall be submitted to the Environmental Sciences Section at the address cited above. Should the permittee fail to monitor during a month in which toxicity monitoring is required, monitoring will be required during the following month. Permit NC0088510 Should any test data from this monitoring requirement or tests performed by the North Carolina Division of Water Quality indicate potential impacts to the receiving stream, this permit may be re -opened and modified to include alternate monitoring requirements or limits. NOTE: Failure to achieve test conditions as specified in the cited document, such as minimum control organism survival, minimum control organism reproduction, and appropriate environmental controls, shall constitute an invalid test and will require immediate follow-up testing to be completed no later than the last day of the month following the month of the initial monitoring.

A construction site will be dewatered. Historically several businesses have been on the site over the many years and include a parking lot, a wax manufacturing facility, a gasoline station, a dry cleaning facility, an auto supply facility, a cotton warehouse, and a printing and newspaper facility. Preliminary results of the groundwater sampling indicate that volatile organic compounds have exceeded groundwater standards. There is the possibility that soil and groundwater contamination exists from prior developments on the site. Water collected from the site would discharge to a stoi ui drain which discharges to Little Sugar Creek. RECEIVING STREAM INFORMATION: Little Sugar Creek is listed on North Carolina's 2006 303(d) impaired streams list for fecal coliform. Estimations for QA, summer and winter 7Q10 flows are zero for Little Sugar Creek. EAA GUIDANCE: Groundwater Remediation System Discharges. You will need to evaluate whether WWTP connection, land application, and infiltration galleries are viable disposal alternatives. While land application might be a feasible alternative in rural areas, it would not be a feasible alternative in downtown Charlotte, where there is no land available for wastewater application. In this instance, you may simply state that land application is infeasible based on land constraints within the city. You will also need to evaluate connection to an existing WWTP (in accordance with Alternative A), since there are some municipalities that have accepted this wastestream in the past. If the municipality will not accept the wastestream, the connection alternative is also considered technologically infeasible. Bank of America/SuperBlock included letter from Charlotte Mecklenburg Utilities that stated it would not accept the remediated groundwater from this project. INSTREAM MONITORING: This is a new facility with no historical instream monitoring data. TOXICITY TEST RESULTS: N/A - Will recommend chronic quarterly toxicity test per guidance for GW remediation projects. PRIORITY POLLUTANT ANALYSIS RESULTS: Results of sample taken 2/2007: • 2-butanone (MEK) - 6.7 ug/1 ---No NC Standard; No Federal Criteria • carbon tetrachloride - 3.6 ug/1 --- Human health standard of 1.6 ug/l. With no dilution instream, this sample would violate the WQ standard. chloroform - 3.6 ug/1 --- No NC Standard: Federal Criteria for Human Health (Organism Only) = 470 ug/1 • di-n-butylphthalate - 13 ug/1 --- No NC Standard (this is considered a laboratory contaminant) • Oil and Grease - <5 ug/1 • pH - 6.73 SU • PCBs (polychlorinated biphenyls) - All <1.0 ug/1 • Barium - 31 ug/1 ---- No NC Standard for Class C waters • Arsenic - <5 ug/1 • Cadmium - <1 ug/1 • Chromium - <5 ug/1 • Lead - <5 ug/1 • Mercury - <0.2 ug/1 • Selenium - <10 ug/1 • Silver - <5 ug/1 • COMPLIANCE REVIEW: NA REASONABLE POTENTIAL ANALYSIS Did not run RPA. Per BPJ, UT Little Sugar Creek has an estimated streamflow of 0 cfs. There was only one data point for most parameters. Only carbon tetrachloride had a hit above the standard. Recommended a limit for that parameter based on that one value. Recommended monitoring for chloroform based on one hit.

It will be submitted as soon as it becomes available. Little Sugar Creek is a Class C waterway. Therefore, there are no restrictions on watershed development or types of discharges. A review of the Catawba River Basinwide Water Quality Plan dated September 2004 and prepared by Mr. Dave Toms with the NC Department of Environment & Natural Resources, Division of Water Quality — Planning does not list NPDES permitting strategies that limit wastewater discharges to particular streams within the basin. Little Sugar Creek is on the 303(d) list as an impaired waterway. There is a Total Maximum Daily Load (TMDL) for fecal coliform of 9.4x1012 cfu/100 ml. Based on the project description and site contaminants, it is not anticipated that fecal coliform will be discharged into the storm sewer. Endangered species are not present in the proposed discharge location. Estimated treatment design flow is 0.03 MGD. Non -Municipal Flow Projections Until operations commence, a reasonable flow projection cannot be determined. Evaluation of technologically feasible alternatives Alternative A. Connection to an Existing Wastewater Treatment System Charlotte -Mecklenburg Utilities is responsible for the sanitary sewer system for the subject site. They do not accept groundwater, stormwater, or other discharges to the sanitary sewer. A letter from Charlotte -Mecklenburg Utility Department (CMUD) denying a request for temporary discharge permit of treated groundwater to the City of Charlotte sanitary sewer system is attached. Alternative B. Land Application Land application would not be a feasible alternative in downtown Charlotte based on land constraints within the city. Alternative C. Infiltration Galleries This alternative cannot be properly evaluated until there is a clear definition of the contaminant level and flow projections. Once dewatering begins, this alternative will be evaluated. NPDES Permit Application 100 North College Street Charlotte, North Carolina ECS Project 08-4158D March 16, 2007 Alternative D. In -Situ Groundwater Remediation Wells In -situ groundwater remediation wells would not be a feasible alternative for this site because the site is being dewatered; a remediation system is not being constructed. Alternative E. Closed -Loop Groundwater Remediation Wells Closed -loop groundwater remediation wells would not be a feasible alternative for this site because the site is being dewatered; a remediation system is not being constructed, Alternative F. Direct Discharge to Surface Waters Direct discharge to the surface water is feasible for this site. Storm drains are located in the vicinity of the site. The discharge to the storm drain will not create a hazardous condition. Other considerations have been met as described previously. Alternative F, direct discharge to surface waters is the most viable option at this time. If you have any questions or comments, please do not hesitate to contact ECS at (704) 525-5152.

Permit NC0088510 EFFLUENT LIMITATIONS AND MONITORING REQUIREMENTS SPECIAL CONDITIONS A. (2) CHRONIC TOXICITY PERMIT LIMIT (QRTRLY) The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant mortality to Ceriodaphnia dubia at an effluent concentration of 90%. The permit holder shall perform at a minimum, quarterly monitoring using test procedures outlined in the "North. Carolina Ceriodaphnia Chronic Effluent Bioassay Procedure," Revised February 1998, or subsequent versions or "North. Carolina Phase II Chronic Whole Effluent Toxicity Test Procedure" (Revised -February 1998) or subsequent versions. The tests will be performed during the months of January, April, July and October. Effluent sampling for this testing shall be performed at the NPDES permitted final effluent discharge below all treatment processes. If the test procedure performed as the first test of any single quarter results in a failure or ChV below the permit limit, then multiple -concentration testing shall be performed at a minimum, in each of the two following months as described in "North Carolina Phase II Chronic Whole Effluent Toxicity Test Procedure" (Revised -February 1998) or subsequent versions. The chronic value for multiple concentration tests will be determined using the geometric mean of the highest concentration having no detectable impairment of reproduction or survival and the lowest concentration that does have a detectable impairment of reproduction or survival. The definition of "detectable impairment," collection methods, exposure regimes, and further statistical methods are specified in the "North Carolina Phase II Chronic Whole Effluent Toxicity Test Procedure" (Revised -February 1998) or subsequent versions. All toxicity testing results required as part of this permit condition will be entered on the Effluent Discharge Monitoring Form (MR-1) for the months in which tests were performed, using the parameter code TGP3B for the pass/fail results and THP3B for the Chronic Value. Additionally, DWQ Form AT-3 (original) is to be sent to the following address: Attention: North Carolina Division of Water Quail Environmental Sciences Section 1621 Mail Service Center Raleigh, North Carolina 27699-1621 Completed Aquatic Toxicity Test Forms shall be filed with the Environmental Sciences Section no later than 30 days after the end of the reporting period for which the report is made. Test data shall be complete, accurate, include all supporting chemical/physical measurements and all concentration/response data, and be certified by laboratory supervisor and ORC or approved designate signature. Total residual chlorine of the effluent toxicity sample must be measured and reported if chlorine is employed for disinfection of the waste stream. Should there be no discharge of flow from the facility during a month in which toxicity monitoring is required, the permittee will complete the information located at the top of the aquatic toxicity (AT) test form indicating the facility name, permit number, pipe number, county, and the month/year of the report with the notation of `No Flow" in the comment area of the form. The report shall be submitted to the Environmental Sciences Section at the address cited above. Should the permittee fail to monitor during a month in which toxicity monitoring is required, monitoring will be required during the following month. Permit NC0088510 Should any test data from this monitoring requirement or tests performed by the North Carolina Division of Water Quality indicate potential impacts to the receiving stream, this permit may be re -opened and modified to include alternate monitoring requirements or limits. NOTE: Failure to achieve test conditions as specified in the cited document, such as minimum control organism survival, minimum control organism reproduction, and appropriate environmental controls, shall constitute an invalid test and will require immediate follow-up testing to be completed no later than the last day of the month following the month of the initial monitoring.

A construction site will be dewatered. Historically several businesses have been on the site over the many years and include a parking lot, a wax manufacturing facility, a gasoline station, a dry cleaning facility, an auto supply facility, a cotton warehouse, and a printing and newspaper facility. Preliminary results of the groundwater sampling indicate that volatile organic compounds have exceeded groundwater standards. There is the possibility that soil and groundwater contamination exists from prior developments on the site. Water collected from the site would discharge to a storm drain which discharges to Little Sugar Creek. RECEIVING STREAM INFORMATION: Little Sugar Creek is listed on North Carolina's 2006 303(d) impaired streams list for fecal coliform. Estimations for QA, summer and winter 7Q10 flows are zero for Little Sugar Creek. EAA GUIDANCE: Groundwater Remediation System: Discharges. You will need to evaluate whether WWTP connection, land application, and infiltration galleries are viable disposal alternatives. While land application might be a feasible alternative in rural areas, it would not be a feasible alternative in downtown Charlotte, where there is no land available for wastewater application. In this instance, you may simply state that land application is infeasible based on land constraints within the city. You will also need to evaluate connection to an existing WWTP (in accordance with Alternative A), since there are some municipalities that have accepted this wastestream in the past. If the municipality will not accept the wastestream, the connection alternative is also considered technologically infeasible. Bank of America/SuperBlock included letter from Charlotte Mecklenburg Utilities that stated it would not accept the remediated groundwater from this project. Bark o'..''mff;calti„perBkx INSTREAM MONITORING: This is a new facility with no historical instream monitoring data. TOXICITY TEST RESULTS: N/A - Will recommend chronic quarterly toxicity test per guidance for GW remediation projects. PRIORITY POLLUTANT ANALYSIS RESULTS: _Results of sample taken 2/2007: • 2-butanone (MEK) - 6.7 ug/1 ---No NC Standard; No Federal Criteria • carbon tetrachloride - 3.6 ug/1 --- Human health standard of 1.6 ug/1. With no dilution instream, this sample would violate the WQ standard. • chloroform - 3.6 ug/1 --- No NC Standard: Federal Criteria for Human Health (Organism Only) = 470 ug/1 ■ di-n-butylphthalate - 13 ug/1--- No NC Standard (this is considered a laboratory contaminant) • Oil and Grease - < 5 ug/1 • pH - 6.73 SU • PCBs (polychlorinated biphenyls) - All <1.0 ug/1 • Barium - 31 ug/1 ---- No NC Standard for Class C waters • Arsenic - <5 ug/1 • Cadmium - <1 ug/1 • Chromium - <5 ug/1 • Lead - <5 ug/1 • Mercury - <0.2 ug/1 • Selenium - <10 ug/1 • Silver - <5 ug/1 • COMPLIANCE REVIE NA REASONABLE POTENTIAL ANALYSIS Did not run RPA. Per BPJ, UT Little Sugar Creek has an estimated streamflow of 0 cfs. There was only one data point for most parameters. Only carbon tetrachloride had a hit above the standard. Recommended a limit for that parameter based on that one value. Recommended monitoring for chloroform based on one hit.
