Ross Jr., Secretary 1646 Mail Service Center, Raleigh, North Carolina 27699-1646 Phone 919-733-4996 \ FAX 919-715-3605 \ Internet http://wastenotnc.org An Equal Opportunity / Affirmative Action Employer – Printed on Dual Purpose Recycled Paper January 10, 2007 Sent Via E-mail & USPS Mr. John J. Husin 5934 Old Pineville Road Charlotte, NC 28217 johnh@carocon.com Subject: Request for Additional Assessment Old Pineville Road 4928 Old Pineville Road Charlotte, Mecklenburg County 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. Page 2 of 2 • 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.
