Tryon Street, 806 S. Church Street, 831 S. Mint Street, 621 and 720 S. Poplar Street, and 301 W. Stonewall Street, and includes the demolition of the former Charlotte Observer Facility (two buildings). This permit will include the management and drainage of potential contact storm water with petroleum affected soil, and also potentially contaminated groundwater. Figure 1 in Appendix A indicates the project location on part of a United States Geological Survey, topographic quadrangle map. The Charlotte Observer structures are separated by Church Street and constructed within basins, formed by subgrade basements and a tunnel beneath Church Street. Therefore, during the demolition and post demolition phases of the project, rain water may collect in these basins, designated the northwest and southeast basins, and the rainwater will have the potential to come in contact with soil that has been found to contain concentrations of petroleum hydrocarbons. Additionally, it is possible that some areas of excavation could reach the capillary fringe or the top of the water table. Previous assessments have identified groundwater affected by petroleum hydrocarbons. The depth to groundwater in the project area ranges from approximately 12 to 30 feet. Although current redevelopment plans seem unlikely to encounter impacted groundwater, this permit application covers the contingent management of this petroleum- impacted groundwater. The maximum contaminant concentrations in soil are presented in Table 1, and the maximum contaminant concentrations in groundwater are presented in Table 2, both in Appendix A. The project will entail utilizing the basins (northwest and southeast) at the locations of both Charlotte Observer structures (post demolition) to contain water from precipitation events, and preventing that water from uncontrolled runoff beyond the Brownfield Site boundary. In the event this contained precipitation water (from each of the basins) does not naturally infiltrate into the soil and evaporate, it will need to be treated with an on-site treatment system and then discharged to the storm water system. Other areas of the site, which do not have known surface or shallow subsurface petroleum contamination, currently have construction storm water management through two NPDES general permits, Phase A: LDUUMUDD-2016-00024 and Phase B: EAA and NPDES Permit Application West Stonewall Street Brownfield Site ATC Project No. 199.GSG.1601 September 7, 2016 ATC Group Services, LLC 2 LDUUMUDD-2016-00029, which directly provides for storm water management through a sedimentation and erosion control plan. Analytical testing as part of the Environmental Management Plan (EMP), Brownfields Project Number 19084-15-60, has identified areas within the basins formed by the building subgrade areas that are impacted by petroleum hydrocarbons, both soil and groundwater, in concentrations both exceeding and not exceeding regulatory standards. Thus, the potential to collect and discharge hydrocarbon affected groundwater and precipitation water exists. Mr. Tom Belnick with the North Carolina Department of Environmental Quality, Division of Water Quality (DWQ) confirmed, after discussion of site conditions, that the project would require National Pollution Discharge Elimination System (NPDES) permitting using Form NCG510000. The NPDES Permit Application Form, provided as Appendix A, also includes a soil analytical table, a groundwater analytical table, the site location on a USGS topographic map, and additional figures illustrating the proposed discharge locations and treatment system. Appendix B contains excerpts from the Phase II Environmental Site Assessment (ESA) Report that are referenced in this document. 1.2 Site Background The former Charlotte Observer newspaper facility, now referenced as the West Stonewall Street Brownfields Property, consists of approximately 9.80 acres across six parcels and will be demolished, including the building foundations. Up to approximately 427,000 square feet will likely be disturbed based on the development encompassing virtually the entire 9.80-acre area of the current site parcels. The excavation of soil, including soil that has been identified as being potentially affected by petroleum hydrocarbons, will be implemented in one of two plans as discussed in the EMP of the Brownfield Agreement. The primary grading plan includes the excavation of a total of approximately 4,630 cubic yards (cy) of petroleum contaminated soil. However, an alternative plan, which calls for the excavation of up to 17,250 cy of petroleum contaminated soil, may be implemented if the property developer determines that removal of soil at greater depths would be beneficial to property marketability. Under either of the two plans, petroleum contaminated soil has the potential to come in contact with precipitation water in the basin areas. The known EAA and NPDES Permit Application West Stonewall Street Brownfield Site ATC Project No. 199.GSG.1601 September 7, 2016 ATC Group Services, LLC 3 contaminants in the soil include the following volatile organic compounds (VOCs): Acetone, Benzene, n- Butylbenzene, sec-Butylbenzene, Ethylbenzene, Isopropylbenzene, Isopropyl Ether, 4- Isopropyltoluene, Methyl Ethyl Ketone, MTBE, Naphthalene, n-Propylbenzene, Toluene, Trichloroethylene, 1,2,4-Trimethylbenzene, 1,3,5-Trimethylbenzene, Xylenes. The known contaminants in the soil also include the following polynuclear aromatic hydrocarbons (PAHs): Acenaphthene, Acenaphthylene, Anthracene, Benzo(a)anthracene, Benzo(a)pyrene, Benzo(b)fluoranthene, Benzo(g,h,i)perylene, Benzo(k)fluoranthene, Chrysene, Dibenzo(a,h)anthracene, Fluoranthene, Fluorene, Indeno(1,2,3-cd)pyrene, 1-Methylnaphthalene, 2-Methylnaphthalene, 3,4-Methylphenol (Cresol), Naphthalene, Phenanthrene, Phenol, Pyrene. The concentrations of petroleum contaminants in the soil are provided in Table 1 of Appendix A. As stated previously, the current redevelopment plans seem unlikely to encounter impacted groundwater. Depth to groundwater at the site ranges from approximately 12 feet to 30 feet bgs. The known contaminants in the groundwater include the following: VOCs: benzene, toluene, ethylbenzene, total xylenes, MTBE, naphthalene, acetone, n-butylbenzene, sec-butylbenzene, bromodichloromethane, chloroform, dibromochloromethane, cis-1,2-dichloroethylene, isopropylbenzene, isopropyl ether, 4-isopropyltoluene, methyl ethyl ketone, methyl isobutyl ketone, n-propylbenzene, styrene, 1-2-4-trimethylbenzene, 1-3-5-trimethylbenzene, trichloroethene, trichlorofluoromethane. The known contaminants in the groundwater also include the following PAHs: 1-methylnaphthalene, 2-methylnaphthalene, naphthalene. The maximum contaminant concentrations in groundwater are presented in Table 2 of Appendix A. The currently available groundwater concentrations were derived from analysis of VOCs via EPA Method 8260B and PAHs via EPA Method 8270, which are standard environmental analyses of environmental media specified in the EPA SW-846 manual. The source of the data for groundwater concentrations includes the Additional Phase II ESA (ATC, 2015) and the AFVR and Groundwater Monitoring Event (AMEC, 2016). Testing of groundwater in impacted areas will be conducted prior to NPDES discharge via the drinking water analyses specified by SW-846 for VOCs (EPA Method 624) and SVOCs (EPA Method 625), to confirm conditions found by the prior analyses. Testing of the NPDES-permitted treatment system conditions will also be conducted by the drinking water methods during discharge treatment. EAA and NPDES Permit Application West Stonewall Street Brownfield Site ATC Project No. 199.GSG.1601 September 7, 2016 ATC Group Services, LLC 4 2.0 ENGINEERING ALTERNATIVES ANALYSIS The North Carolina Division of Water Quality Engineering Alternatives Analysis (EAA) Guidance Document, dated June 23, 2005, requires an evaluation of wastewater disposal alternatives in addition to direct discharge, and the EAA is presented herein. The subject discharge will be from the two previously discussed site basins (northwest basin and southeast basin), resulting from demolition, which are separated by Church Street. The following wastewater disposal alternatives are therefore being evaluated:  Connection to an existing wastewater treatment system  Land application  Infiltration gallery  Collection and disposal off-site 2.1 Connection to an Existing Wastewater Treatment System Charlotte Water was contacted by ATC to determine if this collection water could be discharged to the Charlotte Water’s Publicly Owned Treatment Works (POTW). Charlotte Water did not provide permission to discharge pre-treated water to the sewer system or use their conveyances to discharge pre-treated water. Therefore, POTW discharge for the treated water will not be an acceptable alternative for the discharge of treated dewatering fluids. Discharges under this permit will use the Charlotte Water storm water conveyance system for the discharge of treated water and use of this system. GSLH will formally request access to the storm water system at primary and alternate discharge locations as indicated on Figure 1 and Figure 3 of Appendix A. 2.2 Land Application The land application of water through drip irrigation or spray irrigation is not a feasible alternative for disposal of dewatering fluids at the project site. The site is located in the heavily urbanized uptown Charlotte area, and sufficient permeable land is not available in the vicinity for groundwater application. The land area requirements also entail setbacks of the land application areas from property boundaries. Additionally, the drainage construction project will be conducted EAA and NPDES Permit Application West Stonewall Street Brownfield Site ATC Project No. 199.GSG.1601 September 7, 2016 ATC Group Services, LLC 5 nearby and adjoining to municipal roadways, and unpaved private properties would therefore need to be acquired for land application purposes. According to sales records obtained from Charlotte- Mecklenburg POLARIS (Property Ownership and Land Records Information System), private properties in the project vicinity would cost approximately $1,000,000 to $4,000,000 to purchase. Treatment of the water in each basin, which would be required prior to irrigation, would add to the expense of this alternative. Based on the high expense needed for property purchases, as well as lack of available permeable area, land application is not a feasible alternative. 2.3 Infiltration Gallery An infiltration gallery is a horizontal drain constructed of perforated piping and surrounded by permeable material, such as sand or gravel, which distributes treated water for infiltration to subsurface soils. An infiltration gallery should be able to store and transmit water to the subsurface at the same or greater rate that water is being added to prevent flooding. Assuming the maximum potential discharge rate of 100 gpm (per basin), the surficial silt and clay of the Piedmont would not likely transmit dewatering fluids at a sufficient rate to prevent flooding. ATC personnel have extensive experience with past efforts through non-discharge permitting where infiltration, in Piedmont soils with this flow rate, were unsuccessful, even with the expansion of infiltration galleries beyond original designs. This is further supported through the analysis of subsurface soil conducted during the Phase II ESA (Appendix B, Boring Logs). In fact, the nature of the site conditions that include potential ponded water, indicates that available infiltration will already occur, thereby limiting available area for infiltration. The infiltration galleries would also require extensive land area for construction, which is not available at the property. The site includes 9.80- acres, most of which is projected to be disturbed. Therefore, a single stationary discharge location for each basin would not be feasible, and multiple galleries for each basin would then be necessary. The use of infiltration galleries for discharge of dewatering fluids is infeasible for the reasons of potential flooding and the space required on the site for multiple galleries. 2.4 Collection and Disposal Off-Site The accumulated petroleum-affected water could potentially be pumped from the excavation/construction areas into tanker trucks, transported, and disposed of as liquid non- EAA and NPDES Permit Application West Stonewall Street Brownfield Site ATC Project No. 199.GSG.1601 September 7, 2016 ATC Group Services, LLC 6 hazardous waste. It is estimated that 7,776,000 gallons of water total could be generated over the course of the project from July through December 2016 (approximately 180 days). This is estimated based on the system running at 30 gallons per minute (gpm) over the 180 day period. Based on this quantity of water for this duration, the costs for the pumping, transportation, and storage of the non-hazardous waste liquid would be approximately $6,609,600, based on an estimated inclusive rate of $0.85 per gallon (storage, transportation, and disposal of the contaminated water). The implementation of collection and disposal off-site is not a cost effective method of managing the discharge of the dewatering fluids. EAA and NPDES Permit Application West Stonewall Street Brownfield Site ATC Project No. 199.GSG.1601 September 7, 2016 ATC Group Services, LLC 7 3.0 PROPOSED WATER TREATMENT SYSTEM Appendix A includes the NPDES Permit Application, NCG510000, with supporting documentation. The proposed water treatment system consists of two, in-series, 5,000-pound, liquid-phase granular activated carbon (GAC) vessels. The GAC vessels will be mounted on a tractor-trailer body for transport to locations within the site during demolition and construction activities. Contact water and potentially groundwater extracted from the basins and construction project will be collected into a holding/settling vessel (also referred to as a frac tank) of approximately 21,000 gallons capacity. Two diesel fuel operated transfer pumps will collect the water from the holding tank and route the flow through two, parallel filtration units to remove sediment, and then proceed into the first GAC vessel. The water will then flow into the second GAC vessel for “polishing” and then will flow through an aboveground hose to the designated storm water drain, or its alternate. Figure 4 in Appendix A provides the proposed water treatment system schematic. The treatment system will be portable, and will be transported to staging locations at each basin as needed for dewatering operations. A total of four storm water drains have been proposed for potential discharge, two for each basin, and each with a primary and an alternate discharge point. The storm water drains for the northwest basin are located directly to the west of the basin and also along the southeast side of South Mint Street, approximately 200 feet to the southwest of West Stonewall Street. The storm water drains for the southeast basin are located along the northwest side of South Tryon Street. The final discharge point for the two storm drains for the northwest basin is Irwin Creek and its tributaries, and the final discharge point for the two storm drains for the southeast basin is Little Sugar Creek and its tributaries. Figure 2 of Appendix A illustrates the storm water pathways, including both Irwin Creek and Little Sugar Creek drainage basins. Figure 3 in Appendix A illustrates the locations of the proposed storm drain locations for each of the two basins, with geographical coordinates. Figure 4 in Appendix A provides the process and instrumentation diagram for the proposed treatment system. EAA and NPDES Permit Application West Stonewall Street Brownfield Site ATC Project No. 199.GSG.1601 September 7, 2016 ATC Group Services, LLC 8 A maximum flow rate of 30 gpm was used for the system design. This will be the maximum anticipated flow as averaged over the projected 180 day project. This time period would therefore include periods where the system is not operating at all (no standing water in either basin) and periods where the system would be operating at or near its 30 gpm capacity. The maximum contaminant concentration in the soil (Table 1 in Appendix A) and groundwater (Table 2 in Appendix A) were used in determining the likely influent for the system design and determination of the baseline influent. It is projected that petroleum contaminated contact water and groundwater would be detectable in each of the building subgrade areas (designated the northwest and southeast basins) at a dilution factor ranging from 50 percent to 90 percent, but also could be diluted as much as 99-percent, due to the following factors:  Contaminated soil exceeding regulatory standards, with the potential to create petroleum- contaminated contact water, is present in approximately 50 percent or less of the areas projected to include the building subgrade areas (Figure 6C in Appendix B).  Contaminated groundwater exceeding regulatory standards, with the potential to create petroleum-contaminated water, is present in approximately 10 percent or less of the areas projected to include the building subgrade areas (Figure 8 in Appendix B).  Concentrations of petroleum contaminants would likely be below regulatory standards in precipitation water that would accumulate in the basins.  Concentrations of petroleum contaminants in groundwater would likely be below regulatory standards in approximately 90 percent of the groundwater encountered, as based on the most recent groundwater sampling data.  The low concentrations and low solubilities of the petroleum contaminants in the soil indicate that precipitation contact water would likely be diluted at 99-percent. The following assumptions were made for the treatment system model, based on the preceding information on system operational flow and contaminant concentrations:  A potential maximum of approximately 7,776,000 gallons of water would be treated, based on 10-hour days, a 5-day operational work week, and a 30 gpm flow rate. EAA and NPDES Permit Application West Stonewall Street Brownfield Site ATC Project No. 199.GSG.1601 September 7, 2016 ATC Group Services, LLC 9  A potential maximum of 50 percent of the highest identified petroleum contamination concentration would be present in the water to be treated.  It is likely that 10 percent to 1 percent of the highest identified petroleum contamination concentration would be present in the water to be treated, based on a 90 to 99 percent dilution factor. According to Carbonaire, the vendor ATC is using to provide the treatment system, modeling indicates that a total of 5,184,000 gallons of water can be treated before the initial stages of carbon breakthrough. This condition could be expected to occur at the 120th system operational day. Based on this criteria, the carbon in each of vessels should be replaced at this interval. Assuming wastewater generation occurs, the treatment system influent and effluent will be monitored on regular intervals. Water samples will be collected from the treatment system at a point prior to entering the first carbon vessel (influent), between the two vessels (breakthrough), and after the treatment system (effluent) prior to entering the storm water system. The sampling program will be used to determine influent concentrations, system effectiveness, and the quality of water entering the storm water system. The treatment system will be sampled once per operational week during the first month of operation, and once per operational month thereafter, through the extent of the project. The analytical testing will include laboratory analytical method EPA Method 624 for VOCs and EPA Method 625 for SVOCs. The projected cost for the installation and operation of the treatment system from July to December 2016 is $80,000, which includes the costs for transportation between basins, and one carbon unit change-out (both adsorber tanks). EAA and NPDES Permit Application West Stonewall Street Brownfield Site ATC Project No. 199.GSG.1601 September 7, 2016 ATC Group Services, LLC 10 4.0 DISCUSSION The West Stonewall Street Brownfield Site project includes the demolition of the former Charlotte Observer Facility (two buildings). This permit will include the management and drainage of potential contact storm water with petroleum affected soil, and also potentially contaminated groundwater that is expected to accumulate in the former building subgrade areas, designated the northwest and southeast basins. In review of the alternatives for the handling of this contact water, and potentially groundwater, on-site treatment and discharge to the storm water system through this proposed NPDES permit is the most cost effective and practical solution for this Brownfield project.

(b) Based on the 2B Standards. Bold values indicate the exceedance of the discharge limits. Recommendations: Liquid Phase Carbon Adsorbers Two PC28’s in series, each with 5,000 lbs of granular activated carbon  Benzene is the critical contaminant. MTBE, Acetone, chloroform, dibromochloromethane, cis- 1,2-DCE, MEK, MIBK, and trichlorofluoromethane, which are less adsorbable to carbon than benzene, will be allowed to pass through the carbon adsorbers at effluent concentrations below the discharge limits.  Both adsorbers are predicted to last 65, 120, and 240 days at 100, 50, 10% of the maximum detected concentrations, respectively (see the modeling outputs below).
