(Terracon) has completed the enclosed NPDES Permit Application and supporting documentation for the above -referenced property. Preparation of this NPDES Individual permit application is associated with proposed dewatering, as necessary, during the installation of deep foundations during the planned construction of high-rise, mixed -use tower. Groundwater at site has been impacted by petroleum contamination that has migrated onto the site from a petroleum release incident associated with a former underground storage tank located on the adjacent property to the northwest. MOD CLT Venture LLC proposes to pre -treat the groundwater that is dewatered from caisson boreholes as necessary on -site and then discharge the effluent to the Charlotte - Mecklenburg County municipal stormwater sewer, with ultimate discharge occurring to Little Sugar Creek, under a new individual NPDES permit. As noted on EPA Forms 3510-2D and 3510-2E, MOD CLT Venture LLC is requesting a waiver for the following effluent characteristics: biochemical oxygen demand, chemical oxygen demand, total organic carbon, ammonia, and oil and grease. These parameters, and the remaining listed in Table A of Form 3510-2D and Section 4.2 of Form 3510-2E (total suspended solids, discharge flow, pH, and temperature), have not been collected. However, as the discharge in question will be composed solely of groundwater, it is not anticipated that the effluent will contain constituents that would have an impact on biochemical oxygen demand, chemical oxygen demand, total organic carbon, ammonia, or oil and grease. As such, we respectfully request that requirements with respect to these parameters be waived from effluent monitoring requirements. The permit application has been provided to Charlotte -Mecklenburg Stormwater Services (CMSS) for their review. CMSS has indicated that it is willing to accept discharge from the proposed treatment system. A copy of CMSS correspondence is included in Appendix E.

We anticipate that some of the groundwater dewatered, particularly on the western portion of the property, will be significantly less impacted. However, we proposed to pretreat all groundwater generated as described in this application. 2) Assumed that the treatment system will result in a 99.9% reduction in influent concentrations. Per the activated carbon mesh manufacturer (see attached correspondence), their theoretical models assume 100% adsorption of contaminants to the mesh with breakthrough of constituents gradually occurring as the mesh becomes saturated. In practice, this results in a 2 to 3 log (99% to 99.9%) reduction in concentrations. 3) The estimated effluent concentration (99.9% reduced) were then multiplied by the estimated daily maximum discharge volume (approximately 2,900 gallons) to arrive at a total mass (in this case pounds) per day discharged.

All our theoretical models assume 100% adsorption. Typically we will achieve 100% adsorption at the beginning and then the contaminants gradually breakthrough the bed as the carbon becomes saturated. Adsorption is a two step process, diffusion into the pores of the carbon granules and then adsorption onto the carbon surfaces. Adsorption is influenced by temperature, humidity, and flow (contact time) which are operating conditions; and the contaminants physical properties of molecular weight, polarity, and vapor pressure. The Mass Transfer Zone, is the area within the carbon bed where adsorption occurs. The MTZ moves through the bed from inlet to outlet. Which is why we recommend a lead/lag configuration. When contaminants breakthrough the lead vessel they are captured by the lag vessel. The lead vessel continues to saturate until the media is replaced. The proposed system will have more than the recommended contact time of 7.5 minutes in the lead vessel, if operated at 35 GPM. The proposed system should be operated above 7 GPM to minimize channeling in the vessel. I assume the 2 GPM flow indicated is an average flow. Typically, there is a 2 to 3 log reduction of contaminant concentration until breakthrough of the carbon occurs and the carbon is saturated. Breakthrough is defined as the leading edge of the Mass Transfer Zone. The saturation point is the lagging edge of the MTZ.

A basin delineation completed using the online USGS StreamStats application for North Carolina (https://streamstats.usgs.gov/ss/) indicates the drainage area for the point of interest (StreamStats adjusted coordinates 35.20360, -80.83711 NAD83) is 12 sqmi. For streams in Mecklenburg County, low -flow characteristics published by the USGS are provided in the following reports: (1) The first is a statewide report completed in the early 1990's. It is USGS Water -Supply Paper 2403, "Low -flow characteristics of streams in North Carolina" (Giese and Mason, 1993). An online version of the report is available at https://pubs.usgs.gov/wsp/2403/report.pdf. The report provides the low -flow characteristics (based on data through 1988) via regional relations and at -site values for sites with drainage basins between 1 and 400 sqmi and not considered or known to be affected by regulation and/or diversions. (2) The second is a statewide report published in March 2015. It is USGS Scientific Investigations Report 2015-5001, "Low -flow characteristics and flow -duration statistics for selected USGS continuous -record streamgaging stations in North Carolina through 2012" (Weaver, 2015). The report is available online at https://pubs.usgs.gov/sir/2015/5001/. The report provides updated low -flow characteristics and flow -duration statistics for 266 active (as of 2012 water year) and discontinued streamgages across the state where a minimum of 10 climatic years discharge records were available for flow analyses. Low -flow characteristics estimated for point of interest: Inspection of the most recent USGS statewide low -flow report (#2 above -referenced report) indicates the low -flow characteristics for this streamgage were published. In table 3 on page 26 of this report, the following low -flow statistics are provided: Period of analysis: 1995-2011 climatic years 1 Annual 7Q10 discharge = 1.5 cfs Annual 30Q2 discharge = 4.0 cfs Annual winter 7Q10 (W7Q10) discharge = 2.3 cfs Annual 7Q2 discharge = 2.5 cfs Annual average discharge = 19.2 cfs (period of analysis 1995-2012 water years, table 5 on page 83) Please note: (1) The estimated flows are provided in units of cubic feet per second per square mile drainage area (cfsm). (2) The climatic year is the standard period used for low -flow analyses at USGS continuous -record streamgages. The climatic year is from April 1 through March 31, designated by the year in which the period begins. For example, the 2011 climatic year is from April 1, 2011, through March 31, 2012. Again, please understand the information provided in this message is based on a preliminary assessment and considered provisional, subject to revision pending collection of future data and further analyses. These provisional streamflow statistics are provided via the DWR USGS Low Flows cooperative agreement between USGS and the N.C. Department of Environmental Quality, Division of Water Resources.

The site consists of two contiguous tax parcels (125-175-06 and 125-175-19) totaling approximately 2.83 acres. The northeastern portion of the site is developed with a paved parking lot while the southwestern portion of the site consists of a vacant, grass -covered lot. The site location and layout are shown on Exhibits 1 and 2 of the permit application. MOD CLT Venture, LLC has enrolled the site in the North Carolina Brownfields Program (NCBP; Site ID: 23070-19-060) to assist in its redevelopment of the site into a mixed -use high- rise, mixed -use tower and separate multi -family residential apartment building. Groundwater at site has been impacted by petroleum contamination (see Tables 1 and 2 and Exhibit 3) that has migrated onto the site from a petroleum release incident associated with a former underground storage tank located on the adjacent property to the northwest. During MOD CLT Venture, LLC's proposed high-rise tower development, it is anticipated that petroleum impacted groundwater will be encountered during the installation of caissons for deep foundations and that temporary dewatering will be necessary as part of construction. Preparation of this EAA has been completed in conjunction with a NPDES application for the proposed discharge of pre-treated groundwater associated with MOD CLT Venture, LLC's proposed construction. A description of the proposed project follows. Projections for flow, evaluation of technical and financial feasibility, and Local Government Review are provided in later sections. Charlotte, NC Environmental ■ Facilities ■ Geotechnical • Materials lierracon Memorandum STEP 1. Background and Project Description Terracon has reviewed the potential restrictions identified in the EAA guidance document and does not believe that the identified restrictions will pose an impediment to an NPDES discharge from this location. The discharge will be to Little Sugar Creek and will occur after the groundwater has been treated. A description of the treatment process and contact information are summarized below. A.

Description of Proposed Project The proposed high-rise tower will occupy the entirety of tax parcel 125-175-06, an area of approximately 1.47 acres. Within this area, 141 caissons will be drilled to an average approximate depth of 31 feet below land surface (bls). Of these, 135 caissons will be drilled two feet into bedrock while the remaining six (6) will be drilled 10 feet into bedrock. Based on historical groundwater assessment activities, depth to groundwater in this portion of the site has typically ranged from approximately 20 to 24 feet bls; however, the depth to groundwater encountered by Terracon during 2020 assessment activities was 17 feet bls. As such, it is conservatively anticipated that the water table encountered during the installation of the foundations will be approximately 17 feet bls on average. C. Summary of Process Information and Flow Estimates The discharge will result from the temporary dewatering of caisson boreholes. The boreholes will range in diameter from 2.5 feet to 6 feet and will be advanced via auger rotary and rock core methods. A temporary casing will be driven ahead of the drill tooling to limit infiltration of the groundwater into the borehole. Once a borehole has reached the appropriate depth, it is anticipated that the borehole will remain open for a maximum of approximately one day prior to the installation of the concrete caisson via tremie pipe. Based on Terracon's geotechnical experience in the Charlotte area, groundwater is typically encountered within boreholes that are allowed to remain open overnight at the approximate expected depth of the water table based on the lithological conditions observed in the cuttings (e.g. saturated soil conditions). As such, Terracon conservatively assumes that groundwater will rise to the depth of the water table within the boreholes prior to caisson installation. Based on the caisson drilling schedule and assuming an average depth to groundwater of 17 feet bls, the anticipated total volume of groundwater within the boreholes that will require dewatering is approximately 205,000 gallons. The calculations for this volume are provided in Table 3 of the permit application. Groundwater will be directed into a frac tank which discharges into a treatment train consisting of a bag filter (to remove sediment) and two in -line TIGG Duosorb 1000 steel vessels each containing 1,000 pounds of reactivated carbon 8x30 mesh, as detailed in the NPDES permit application. The technical specifications of the treatment system are provided in Appendix D of the permit application. Please note that while the proposed pre-treatment is not considered a groundwater remediation treatment for the purposes of reducing petroleum concentrations of impacted groundwater within the subsurface at the site, for the purposes of this EAA and the NPDES Permit Application, it is referred to as a groundwater remediation system below. Charlotte, NC Environmental • Facilities • Geotechnical • Materials lrerracon Memorandum It is anticipated that approximately two boreholes can be completed per day and that the overall deep foundation installation work will occur over an approximate four -month period. Based on the projected construction schedule, Terracon anticipates that the average discharge during working days will be approximately 2,900 gallons per day (GPD) of work. Per the carbon filter manufacturer, the system should be operated at above 7 gallons per minute (GPM) to minimize channeling within the carbon mesh of the vessel (and thus preferential depletion within that portion of the mesh). As such, the system will only be operated periodically once the frac tank approached maximum capacity, and a pump will be utilized to maintain an average flow rate of 10 GPM. Table 1 summarizes the caisson drilling schedule and volume calculations. D. Low Flow Data for Receiving Stream Low flow information for the receiving water(s) was obtained from the US Geological Society (USGS)and the NCDEQ in Raleigh, North Carolina. Correspondence from the agencies is provided in Attachment A. Generally, the discharge from the basin will be outfall 1 through underground piping. From the point of discharge, underground piping discharges to a topographic depression in which stormwater ultimately flows into Little Sugar Creek. The USGS provided the following low -flow statistics based on a period of analysis of 1995 through 2011 climatic years: Frequency Discharge 7Q10 1.5 cubic feet per second (cfs) 30Q2 4.0 cfs W7Q10 2.3 cfs 7Q2 2.5 cfs Based on the USGS-provided information, Little Sugar Creek is not considered a zero -flow stream, and is therefore not subject to zero -flow stream restrictions as set forth in 15A NCAC 2B.0206(d)(2). STEP 2. Reasonable Projections for Flow As discussed in the EAA Guidance Document, non —municipal flow projections for groundwater remediation projects are based on engineering design considerations and/or production projections rather than population projections. As discussed in Step 1C above, the anticipated flow associated with the temporary construction dewatering activities will be approximately 2,800 GPD. As there currently is no discharge from the site to the basin, the total anticipated discharge is 2,800 GPD. Charlotte, NC Environmental • Facilities ■ Geotechnical • Materials lrerracon Memorandum STEP 3. Evaluate Technologically Feasible Alternatives As discussed in the EAA Guidance Document, discharges from groundwater remediation systems are required to evaluate whether wastewater treatment plant (WWTP) connection, land application, infiltration galleries, in -situ groundwater remediation wells, or closed -loop groundwater remediation wells. As these alternatives have not been deemed technologically feasible, as discussed below, Terracon has also considered closed -wastewater reuse, discharge to surface waters, and combinations of the above as possible alternatives. A. Connection to an Existing WWTP The Charlotte -Mecklenburg Utilities (CMU) has discontinued accepting groundwater discharges. Specifically, the City of Charlotte Sewer Use Ordinance prohibits the discharge of groundwater in Section 23-79 (14) without permission from the CMU-System Protection (SP). Based on conversations with representatives of SP, CMU will not accept discharge of the dewatered groundwater, making this treatment alternative infeasible. B. Land Application The facility is located at 615 East Morehead Street in Charlotte, North Carolina. This location is just outside Uptown Charlotte in an urban area consisting predominantly of commercial development. Ground cover in the area is predominantly already developed hardscape. While the southwestern portion of the site consists of vacant, grassed land, there will be on -going construction activities on the property during the dewatering activities, and land application of the discharge would interfere with that construction. Space on the site is so limited that the proposed construction includes a sub -grade infiltration basin to handle construction related stormwater discharge. The basin design has been based on the site -specific stormwater drainage needs. The addition of dewatered groundwater from the caisson installations would exceed the design parameters of the infiltration system. Based on the design and land constraints and the available land, land application is not feasible at this time. C. Infiltration Galleries As discussed above, there is not space on the site to install an infiltration gallery. As such, infiltration galleries are not a technologically feasible alternative. Charlotte, NC Environmental • Facilities • Geotechnical • Materials lrerracon Memorandum D. In -Site or Closed -Loop Groundwater Remediation Wells As the proposed discharge is temporary, and it would be difficult to protect/maintain wells on an active construction site, permanent re -injection well infrastructure is unnecessary and not technically feasible. E. Wastewater Reuse The site will consist of an active construction site during the dewatering activities. As such, there are no site processes available in which the dewatered groundwater could be reused. Therefore, wastewater reuse is not technically feasible. F. Off -site Disposal of Discharge via Vacuum Truck The off -site disposal of temporarily containerized dewatered groundwater via vacuum truck ("batch and haul") is a technologically feasible alternative for disposal. However, as discussed in Step 5 below, it is not an economically feasible alternative. G. Direct Discharge to Surface Waters Surface water discharge has also been determined to be a technically feasible alternative for disposal of the dewatered groundwater based on the presence of Charlotte -Mecklenburg stormwater infrastructure at/adjacent to the site and its ultimate discharge to surface water. The discharge from the outlet of the treatment system will be directed into a stormwater intake located in an existing stormwater detention basin located in the northeastern corner of the property. Discharge from the basin ultimately discharges into Little Sugar Creek. Refer to Exhibit 1 for the location of the facility in relation to the Little Sugar Creek. Exhibit 2 shows the location of Outfall #1. STEP 5. Evaluate Economically Feasible Alternatives "Batch and haul" and surface water discharge have been determined to be the only technically feasible alternatives for disposal of dewatered groundwater. As the proposed discharge is temporary and will only occur during an approximate 4-month period during 2022, a 20-year present value cost analysis (PVCA) has not been completed. However, Terracon has completed a comparison of the overall projected costs of the two identified technologically feasible alternatives. Below is a table comparing costs for the disposal of the dewatered groundwater via "batch and haul" versus surface water discharge under a NPDES Individual Permit. The costs are estimates and are limited to those elements specific to the discharge, e.g. operational Charlotte, NC Environmental • Facilities • Geotechnical • Materials lierracon Memorandum requirements, treatment costs, monitoring costs and maintenance. As the NCBP and disposal facility will require characterization sampling of groundwater exported from the site via "batch and haul," and periodic sampling of pre-treated groundwater discharge is anticipated under the NPDES permit requirements, it has been assumed that the difference in sampling costs (labor and laboratory analysis) is negligible. In addition, as dewatered groundwater will be containerized within a rented frac tank in either scenario, its cost has not been included in the table below. Description Present Value (2022 only) "Batch and Haul" NPDES Discharge Vacuum Truck Services (assumes 40 mobilizations of a 5,000-gallon tanker; assumes 8 hour round trips at $125/hour) $40,000 NA Disposal ($0.35/gallon) $71,530 NA Bag Filter Rental (4 months)* NA $2,300 Carbon Filter Rental (4 months)* NA $12,080 Disposal of Carbon Material NA $1,500 TOTAL COST $111,530 $15,880 *Includes mobilization/demobilization fees Based on the above cost analysis, the opportunity cost to pursue a "batch and haul" alternative to NPDES-permitted discharge under an individual permit is $95,650. As such, the NPDES permit is by far the most economically feasible option for disposal of the dewatered groundwater at the site.

A basin delineation completed using the online USGS StreamStats application for North Carolina (https://streamstats.usgs.gov/ss/) indicates the drainage area for the point of interest (StreamStats adjusted coordinates 35.20360, -80.83711 NAD83) is 12 sqmi. For streams in Mecklenburg County, low -flow characteristics published by the USGS are provided in the following reports: (1) The first is a statewide report completed in the early 1990's. It is USGS Water -Supply Paper 2403, "Low -flow characteristics of streams in North Carolina" (Giese and Mason, 1993). An online version of the report is available at https://pubs.usgs.gov/wsp/2403/report.pdf. The report provides the low -flow characteristics (based on data through 1988) via regional relations and at -site values for sites with drainage basins between 1 and 400 sqmi and not considered or known to be affected by regulation and/or diversions. (2) The second is a statewide report published in March 2015. It is USGS Scientific Investigations Report 2015-5001, "Low -flow characteristics and flow -duration statistics for selected USGS continuous -record streamgaging stations in North Carolina through 2012" (Weaver, 2015). The report is available online at https://pubs.usgs.gov/sir/2015/5001/. The report provides updated low -flow characteristics and flow -duration statistics for 266 active (as of 2012 water year) and discontinued streamgages across the state where a minimum of 10 climatic years discharge records were available for flow analyses. Low -flow characteristics estimated for point of interest: Inspection of the most recent USGS statewide low -flow report (#2 above -referenced report) indicates the low -flow characteristics for this streamgage were published. In table 3 on page 26 of this report, the following low -flow statistics are provided: Period of analysis: 1995-2011 climatic years 1 Annual 7Q10 discharge = 1.5 cfs Annual 30Q2 discharge = 4.0 cfs Annual winter 7Q10 (W7Q10) discharge = 2.3 cfs Annual 7Q2 discharge = 2.5 cfs Annual average discharge = 19.2 cfs (period of analysis 1995-2012 water years, table 5 on page 83) Please note: (1) The estimated flows are provided in units of cubic feet per second per square mile drainage area (cfsm). (2) The climatic year is the standard period used for low -flow analyses at USGS continuous -record streamgages. The climatic year is from April 1 through March 31, designated by the year in which the period begins. For example, the 2011 climatic year is from April 1, 2011, through March 31, 2012. Again, please understand the information provided in this message is based on a preliminary assessment and considered provisional, subject to revision pending collection of future data and further analyses. These provisional streamflow statistics are provided via the DWR USGS Low Flows cooperative agreement between USGS and the N.C. Department of Environmental Quality, Division of Water Resources.

Depending upon the application, this activated carbon can provide performance similar to virgin activated carbon at a reduced cost. TYPICAL PROPERTIES TIGG 5DR 0830 U.S Sieve, 90 wt% min 8 x 30* Iodine Number, mg/g 750 Apparent Density, (dense packing) g/cc 0.45 - 0.55 Ibs/ft3 28 - 34 Moisture - wt% max (as packed) 2 Abrasion No. - min 70 * Size 840 is also available TYPICAL APPLICATIONS This activated carbon can be used to remove: • BTEX and other organic compounds from ground water. • Organic compounds from wastewater and potable water. • Trace organics from process streams such as alcohols, glycerine, MEA, acids, etc Standard packaging of the activated carbon is in 50 pound bags or 1000 pound supersacks. Wet drained activated carbon adsorbs oxygen from the air. Therefore, when workers need to enter a vessel containing wet activated carbon, they should follow confined space/low oxygen level procedures. Activated carbon dust does not present an explosion hazard. 800-925-001 1 I TIGG, LLC www.TIGG.com 1 Willow Avenue www.TlGGtanks.com Oakdale, PA 15071 Purifying Air & Water APPENDIX E CHARLOTTE MECKLEBURG CORRESPONDENCE '1STORM Charlotte -Mecklenburg WATER StormWater.CharMeck.org Services December 8, 2021 NC Department of Environmental Quality Mooresville Regional Office Division of Water Resources - Water Quality Permitting Unit 610 East Center Avenue Suite 301 Mooresville, NC 28115 Subject: NPDES Permit Application - request to discharge into the City of Charlotte municipal stormwater system at 615 East Morehead Street (North Carolina Brownfields Site No. 23070-19- 060) in Charlotte, NC Division of Water Resources: Regarding Terracon Consultants, Inc.'s request on behalf of MOD CLT Venture LLC in their NPDES permit application to discharge treated water from a remediation system at the above -referenced location into Charlotte's stormwater system, Charlotte Mecklenburg Storm Water Services (CMSWS) approves the discharge. CMSWS would like to make the permittee and NC DEQ aware of the following considerations and information: • CMSWS reserves the right to access, inspect, sample, and review documentation regarding the groundwater treatment system at any time. • In the event of an illicit discharge, bypass, or exceedance of permit discharge limits, MOD CLT Venture LLC or its consultant shall immediately notify CMSWS and immediately implement corrective actions. • CMSWS reserves the right to rescind approval to discharge to the City of Charlotte's MS4 for due cause including gross improper operation of the system, an established trend of discharge limit exceedances, failure to provide notification of illicit discharges, system bypasses, and similar reasons. • CMSWS does not guarantee adequate capacity is available to permitted dischargers to keep any property or street free of water or harm as a result of this discharge. It is recommended that if discharge flows are anticipated to be high, the discharger should avoid discharging during wet weather. • CMSWS takes no responsibility for backflows from the public drainage system into the permitted discharger's system.
