Easley, Governor William G. Ross Jr., Secretary Dexter R. Matthews, Director Ms. Heather St. Aubin-Stout and Mr. Gray Stout 45 Alcorn Lane Salisbury, North Carolina 28144 go Dear Ms. St. Aubin-Stout and Mr. Stout: IT • NCDENR July 1, 2004 Monitor Well Sampling Former Heather St. Aubin Residence 3132 Airlie Street Incident #6401 Intermediate Risk Classification Mecklenburg County The UST Section of the Mooresville Regional Office received the subject report on June 24. 2004. Upon review, it was noted that monitor well MW-1 contained C9 — C22 Aromatics at a level of 78, 945 parts per billion (ppb). I have researched surface water regulations and found that even though the Water Quality Standards found in 15A NCAC 2B .0200 do not currently list a freshwater standard for C9 — C22 Aromatics, a National Criteria standard of 20 ppb is applicable for freshwater. In this instance, the subject site mill remain intermediate risk until you can demonstrate that surface water is no longer at risk from the heating oil UST release. If you should have any questions, I can be reached at (704) 663-1699 ext. 236.
