1.0 INTRODUCTION
1.1 Site Location
The Prime Equipment RmOMIMAY #408 is located at 3521 Asbury Avenue in Charlotte,
Mecklenburg County, North Carolina. The site is currently owned by
and is operated as a equipment rental facility. Figure I is a
general site location map obtained from a copy of the USGS 7.5 minute Derita Quadrangle Map.
1.2 Purpose
The purpose of this report is to present the proposed design of a groundwater remediation system
at the Prime Equipment 40 for approval to discharge wastewater effluent
through the National Pollutant Discharge Elimination System (NPDES) under a North Carolina
Category 51 General Permit. Groundwater in the area of the Prime Equipment Rental facility
has been impacted by petroleum hydrocarbons from possible leaking underground storage tanks.
Substances that exceed the groundwater standards for North Carolina are benzene, toluene,
ethylbenzene, xylenes, MTBE, naphthalene and ethylene dibromide (EDB). Phenanthrene is also
present in the dissolved phase, but is not currently listed in the North Carolina groundwater
standards. Approximately 0.4 feet of liquid phase hydrocarbons were detected in monitoring
well MW-1, during previous site assessment investigations (SPATCO Environmental, 1992).
Figure 2 illustrates the location of monitoring wells and proposed treatment system. The
anticipated flow rate from the onsite treatment works is approximately 2 gpm (2,880 gpd).
2.0 WASTEWATER EFFLUENT DISPOSAL OPTIONS
2.1 Sanitary (POTW) Treatment
This option is not considered feasible since the City of Charlotte is no longer accepting
wastewater from groundwater remediation systems.
2.2 Groundwater Injection
Groundwater injection into the water bearing formation is impractical due to the relatively low
hydraulic conductivity of the site. Initial modeling results indicated that the injection wells
Prime Equipment Rental #408, Charlotte, NC, NPDES Permit Applicafion, WO 0-5402, 8-24-94

would require an increased pumping rate from the treatment system in order to capture the
injected treated effluent. This in to leads to an increased injection rate. Additional recovery
wells, injection wells and storage tanks would be required and, as such, would tend to make this
option prohibitively expensive.
2.3 Groundwater Inftitration Galleries
Groundwater infiltration into surface soils is impacted due to the layout of the site. Without
reloacting existing structures and utilities and accessing adjacent property, there is no area
upgradient of the hydrocarbon plume in which an infiltration gallery can be built.
2.4 Spray Irrigation
Spray Irrigation is not feasible since approximately 65 percent of the site is rendered impervious

Surface discharge into the existing Southern Railroad drainage ditch west of the site is viewed
as the only practical alternative. The ,discharged effluent will, follow the existing su ace water
runoff pathways and eventually flow into Irwin Creek. Irwin Creek, which provides surface
drainage from the surrounding watershed, including the subject site, discharges into Sugar Creek
and eventually into the Catawba River. Figure 3 is a City of Charlotte topographical map
showing the location of the porposed discharge point and pathway of flow to Irwin Creek (also
shown in Figure 1),
3.0 WASTEWATER CHARACTERISTICS

in the treatment unit. The pneuamatic pumps installed in both recovery wells, RW- I and RW-2,
will be a 3.5-inch diameter Clean Environment, Model Short AP-4/TL, rated at 3 gpm using 80
psi with three feet of submergence of the inlet. The specified model shall be top loading
configured in order to collect LPH and water. Both pumps will be constructed of stainless steel,
brass, delrin, nylon, viton, Teflon* and FRI-**O. Operation an performance information is
included in Appendix A.

Impacted groundwater will be transferred to the treatment unit via 1-inch 'PVC pipe. All piping
will be installed below grade at a depth no lessthat 36 inches to minimize interference to the
facility's operations and reduce the potential effects from freezing temperatures. At the
treatment unit, the wastewater will enter an oil/water separator. The oil/water separator is
speciited as a fiberglass Hydra -Flo Technologies, Model DPO02-53 (or equivalent) rated.. at 0.5
to 6 gpm based on removal efficiencies of 20 microns at the low flow rate and 30 microns at
the high flow rate. The separation chamber is fitted with DYNAPAK cross corrugated
coalescing media. The entire separtor includes a removable lid with quick release latches and
vapor seal gasket to facilitate easy maintenance. Operation and performance information is
included in Appendix A. Liquid phase hydrocarbons were gravity fed from the oil/water
separtor to a 270 storage tank.
The wastewater effluent from the oil/water separator will also be gravity fed into 120-gallon
steel surge tank. From the surge tank, recovered groundwater will be pumped into a low profile
air_ tripp r . The air stripper will be specified as a North East Environmenta Products Shallow
Tray', model 1331-P, (or equivalent) with three trays and rated at 0.5to 15 ,gpm (liquid flow
rate) and 150 c (maximum airflow). The specified air stripper shall be capable of treating a
design influent flaw rate of 2 !gpm and produce results better than the target levels indicated in
Table 1. From the air` stripper, the effluent will then be pumped through granular activated
carbon (CAC) vessels specified as Carbonair, model P-1 carbon absorbers (or equivalent)
designed for a maximum flaw rate of 10 g m at 150 psi. Operation and performance
information is included in Appendix A.
Effluent from the treatment system will be discharged via a 3-inch PVC pipe into a drainage
ditch ;located west of the site.

4#4 System Security and Safety Measures
The ,groundwater treatment system will be housed and secured within an aluminum utility shed
to prevent tampering, and provide a relatively constant operation temperature. Bath the supply
d discharge lines will be buried below grade with stub -ups inside the utility shed. ' Electrical
power will be provided in the same manner. The recovery wells will be provided with a trafice
rated, steel well vault, with belt down cover to prevent tampering.
Inside the utility shed, the control panel will have clearly marked and labeled electronic switches
d ether items. All piping will be clearly labeled as influent or effluent and include direction
of flaw. Each major conponent of the groundwater treatment system will utilize manual valves
for all influent and effluent piping. Both the oil/water separator, surge tank and air stripper will
be equipped with high and low level sensors and alarms which will be relayed to the control
panel.
4#5 Operation and Maintenance
A telemetry communications system will also be included in this system. It will be installed
onsite and linked directly by modern. This system will provide daily information can system
operation, including flow rates and system operating conditions. The telemetry system will also
notify the office of system malfunctions so that appropriate personnel could be mobilized to the
site for system maintenance in a timely and efficient manner. Routine preventive maintenance
inspections by a trained system technician will occur monthly throughout the entire life of the
project. During the inspection visit, the system will be adjusted to maintain treatment efficiency
d compliance.
4#6 Fallow -Up Monitoring, System Evaluation, and Reporting:
Monitoring of the groundwater treatment system will be accomplished by utilizing sampling ports
installed between the air stripper and the first GAC unit, between the first and second GAC unit,
and fallowing the second GAG unit., Treatment samples will be screened with a Photovac C.C.
} to ensure discharge quality and prevent carbon breakthrough.

Effluent samples will be collected monthly to ensure that the system is performing as required
and to comply with the NPDES Permit. Immediately after start up, one effluent sample will be
collected and analyzed for purgeable aromatic hydrocarbons using EPA method 602 plus MTBE
and for polynuclear aromatics using EPA method 610. The effluent flow rate will be monitored
on a weekly basis by a continuous totalizer flow meter just prior to discharge. The monthly
monitoring activities will also include field measurement of groundwater levels in the monitoring
wells in order to verify the actual dimensions of the groundwater capture zone produced by the
recovery well. Based on information obtained during these monitoring inspections, the recovery
pump flow rates and other system parameters may be adjusted to optimize the removal efficiency
of the system. All wells and the treatment system effluent will be sampled and analyzed
quarterly using EPA Method 602 plus MTBE and EPA Method 610 to document the remedial
progress.
