Brownfields Project Number 10061-06-60
Dear Mr. Huson:
The North Carolina Department of Environment and Natural Resources (DENR) reviewed the currently
available site information for the Old Pineville Road Brownfields Property. During the review process data gaps were
identified. Additional assessment activities are required to assist in making risk management decisions for inclusion in
the brownfields agreement.
During the evaluation process, the following sources were utilized: the Letter of Intent (LOI) dated November
8, 2006 and Phase I Environmental Site Assessment dated September 1, 2006 prepared by ECS Carolinas, LLP (ECS)
and Proposal for Phase II Environmental Site Assessment prepared by ECS dated September 22, 2006. The following
assessment activities are necessary to complete the brownfields review process:
• General: The most recent Inactive Hazardous Sites Program Guidelines for Assessment and Cleanup
(http://www.wastenotnc.org/sfhome/stateleadguidance.pdf ) should be followed, which in turn relies upon EPA's
Environmental Investigations Standard Operating Procedures and Quality Assurance Manual (a .pdf version is
available on their website at http://www.epa.gov/region4/sesd/eisopqam/eisopqam.html). Request Level 2 QA/QC
data packages from a N.C. certified environmental laboratory.
• Soil Assessment: Install five soil borings on the property to a total depth of 4-feet. Two soil boring along the
drainage ditch in the southern portion of the property. One soil boring in the stained soil patch identified in the Phase I
ESA. Two soil borings around the former manufacturer building. See attached map for approximate locations, actual
location to be determined in the field.
o Soil Sampling: Collect the sample with the highest PID/FID reading. If no significant reading on the
PID/FID are detected, collect the surifcal sample at 0-1 ft for laboratory analysis.
o Background Sampling: soil samples to determine background site levels can be collected in area away
from site operations.

• Groundwater Assessment: Install four shallow temporary groundwater monitoring wells on the property. See
attached map for approximate well locations, actual locations and depths will be determined in the field. For reference
the shallow saprolite wells (~10 ft of screen across the water table).
o Soil Sampling: Collect continuous split spoon samples in the newly installed monitoring wells.
Perform field screening and record the soil lithology. Collect approximately two soil samples, surficial (0-1 ft) and
above the water table (to be determined in the field). Soil samples are not required for the deep well.
o Groundwater Sampling: Collect groundwater samples from the newly installed groundwater
monitoring wells. Record depth of static groundwater in each well prior to purging activities, and field parameters
(e.g., temperature, dissolved oxygen, pH, turbidity, and conductivity) prior to sampling activities for summary report.
Contain purge water for analysis prior to disposal following approval by DENR. In lieu of sampling the containers,
the consultant may rely on sample analysis for disposal options. The ultimate disposal information must be included in
the report.
• Surface Water Sampling: Use standard operating procedures for collecting grab samples in the storm drain
ditch, if water is present. Collect two sampling from the water entering the property and downstream leaving the
property.
• Sediment Sampling: Collect sediment sample from storm drain ditch where adjacent property outfall enters the
Brownfields Property.
• Laboratory Analysis: Submit soil and groundwater samples to a NC-certified laboratory and analyze for
volatile organic compounds (VOCs) by EPA Method 5035/8260, semi-volatile organic compounds (SVOCs) by EPA
Method 8270, RCRA total metals and polychlorinated biphenyls (PCBs) by EPA Method 8082. Submit surface water
and sediment samples for VOCs, SVOCs, and metals. Provide complete original laboratory reports and associated
laboratory QA/QC documentation in the final report to DENR.
• Figures & Tables: Provide groundwater elevation map and concentration map(s) for contaminants detected
above applicable standards for groundwater. Include groundwater iso-concentration lines above state standards.
Provide a summary table of the detected concentrations versus state standards and include historical data, if available.
• Site Investigation: Provide additional information to the maintenance and operations of the former Queen City
Boiler Corporation such as years of operations or contacting a former employee, if possible.
• Summary Report: Provide a written letter report with discussion of the extent of contamination, maximum
concentrations, and summary of sampling activities.
Please note that installed and sampling of soil borings around the former manufacturing building may be
delayed until the building is razed and demolished due safety reasons. The sampling requirement would then be
included in the Brownfields Agreement Work to be Performed. Once these activities are complete, we will determine
if any additional information is needed to complete our evaluation of site risks and preparation of the draft Brownfields
Agreement. If you have any questions regarding this letter, please contact me at (704) 661-0330 or via e-mail at

Carolyn Minnich
