Re: Additional Soil Sampling Work Plan
Former Lida Facility
2208-2222 South Blvd.
Charlotte, North Carolina
H&H Job No. ARP-001

Dear Carolyn:

Hart & Hickman, PC (H&H) is pleased to present this brief work plan to conduct additional soil
sampling at the former Lida facility located at 2208-2222 South Blvd. The purpose of our
sampling will be to speciate the chromium previously detected in soil samples above a
concentration of 44 mg/kg. These soil samples are GP-17 (4 ft), GP-18 (4 ft), and BG-2 (6-8 ft).

H&H will advance three hand auger borings at the locations of previous borings GP-17, GP-18,
and BG-2. At each location, a core machine will be used to core through the surface concrete at
GP-17 and GP-18 and the surface asphalt pavement at BG-2. Following coring the surface
material, a decontaminated hand auger will be advanced to the depth of the previous soil sample
from that boring, and a sample will be collected at that depth. The soil samples will be collected
for analysis of total chromium and hexavalent chromium. Trivalent chromium will be
determined by subtracting the total chromium concentration from the hexavalent chromium
concentration.

Following completion of our field activities and receipt of the analytical data, a brief letter report
will be prepared which describes the methods and results of our activities. The report will
include a map depicting the locations of the borings, soil boring logs, a comparison of the
detected hexavalent and trivalent chromium detections to the DENR Inactive Hazardous Sites
soil remediation goal, laboratory analytical data including quality assurance/quality control data,
and conclusions concerning our activities.

We look forward to your approval of this work plan. Please contact me if you have any
questions or need additional information.

Very truly yours,

Hart & Hickman, PC
