The proposed area of remediation by injection well technology is within the 100 year floodplain (blue shading) of Big Marsh Swamp. Ground surface elevation at the vicinity of MW-5 & 5A and the injection area is approximately 126' to 127 +/- msl and the 100 year floodplain elevation mapped for the area is approximately 128' to 129' +/- msl. There are no groundwater users in the area of the remediation site. Down gradient of injection site is Big Marsh Swamp. Any private groundwater supply wells near the injection site would be across Big Marsh Swamp and the nearest water supply well north of Big Marsh Swamp would be at least 3000' or more away. No major or identified industrial/commercial sources of pollution at or near the landfill site (within 2000' of the landfill property boundary). Possible minor sources of groundwater impacts in the area (other than the disposal units) would be maintenance of equipment at the yard waste area located east of the C&D landfill (approx. 700' from MW-5 & 5A). A copy of the final UIC permit should be provided to the Solid Waste Section in the Division of Waste Management. The contact person for this site is Ms. Elizabeth Werner (919) 508-8496.

Williams, Pharm.D., Toxicologist Medical Evaluation and Risk Assessment Uni Occupational and Environmental Epidemiology Branch North Carolina Department of Health and Human Services SUBJECT: Use of Non -Biological Product by Regenesis to Enhance Biodegradation of Contaminated Groundwater Carmen Hooker Odom, Secretary I am writing in response to a request for a health risk evaluation regarding the use of a non -biological product by Regenesis to enhance biodegradation of contaminated groundwater. Based upon my review of the information submitted, I offer the following health risk evaluation: 1. Ingestion may result in burns to the lips, tongue, and mouth. Exposure to the eyes can cause distortion of cellar membranes, loss of corneal, conjunctival and lens epithelium and loss of endothelium of the cornea and blood vessels. Inhalation may produce upper airway edema, respiratory failure, wheezing, pulmonary edema, and pneumonitis. Skin exposure may cause pain, redness, irritation and severe burns (Micromedex TOMEs Plus System CD-ROM Database, Volume 71, 2007). 2. If the products are released into the environment in a way that could result °' in a suspension of fine solid or liquid particles (e.g., grinding, blending, vigorous shaking or mixing), then proper personal protective equipment should be used. The application process should be reviewed by an c.' industrial hygienist to ensure that the most appropriate personal protective equipment is used. O 3. Persons working with this product should at least wear goggles or a face shield, gloves, and protective clothing. Face and body protection should Location: 5505 Six Forks Road, 2nd Floor, Room D1 • Raleigh, N.C. 27609 An Equal Opportunity Employer be used for anticipated splashes or sprays. Again, consult with an industrial hygienist to ensure proper protection. 4. Eating, drinking, smoking, handling contact lenses, and applying cosmetics should never be permitted in the application area during or immediately following application. Safety controls should be in place to ensure that the check valve and the pressure delivery systems are working properly. 5. The Material Safety Data Sheets should be followed to prevent adverse reactions and injuries. 6. Access to the area of application should be limited to the workers applying the product. In order to minimize exposure to unprotected individuals, measures should be taken to prevent access to the area of application. 7. Violent reactions or ignition could occur under the appropriate conditions with acids, alcohols, p-bis (1, 3-dibromoethyl) benzene, cyclopentadiene, germanium, hyponitrous acid, maleic anhydride, nitroalkanes, 2- nitrophenol, potassium peroxodisulfate, sugars, 2, 2, 3, 3- tetrafluoropropanol, and thorium dicarbide. Measures should be taken to prevent such reactions (Micromedex TOMEs Plus System CD-ROM Database, Volume 71, 2007). 8. Measures should be taken to prevent contamination of existing or future wells and surface waters that may be located near the application area. Please do not hesitate to call me if you have any questions at (919) 707-5912. ear L:,y
