ATC Associates of North Carolina, P.C. (ATC), on behalf of Safety-Kleen Systems, Inc. (S-K),
previously submitted an Injection Permit Application for the above referenced site on August 19,
2011. The NCDENR Aquifer Protection Section (APS) approved the application on October 21,
2011 under the permit number referenced above.
The original permit application provided details for two phases of injection, Phase I and Phase II.
The Phase I injection was completed on December 14, 2011. Attachment I contains an injection
event record for the Phase I injection event. During the Phase I injection event, the target
injection depth could not be reached due to direct -push refusal. Based on data gathered during
the Phase I injection, ATC proposes to modify the proposed scope for the Phase II injection. The
Phase II injection will include injection into six permanent injection wells. Per our recent
telephone conversation, Attachments 2 through 5 contain excerpts from the injection permit
application which are proposed to be modified during the Phase II injection scope.
If you have questions or require additional information, please do not hesitate to contact us at
[phone].
Sincerely,
ATC Associates of North Carolina, P.C.

Iniection Report for the Safety Kleen site in Charlotte, NC
Sent via email: Justin Ballard
Innovative Environmental Technologies, Inc. (IET) attempted an injection event on December 15,
2011 at the Safety-Kleen site in Charlotte, NC. Due to field restrictions only one injection location
was attempted, and one interval completed.
IP-134 shown below was injected at the 15-17' depth using double the amount of persulfate and
peroxide originally proposed (for that interval) because drilling refusal occurred at 19'. No other
injections were attempted due to shallow refusal across the site using a direct -push drilling rig.
Although the 17' depth was reached at one other location, (IP-131), it was determined that the
installation of nested, permanent injection wells would be a more efficient way of introducing the
proposed treatment slurry. An injection Log for IP-134 is included below in figure 2.

began operations on June 5, 1978. The facility currently maintains a Part B Resource Conservation and
Recovery Act (RCRA) permit for hazardous waste storage. In the early 1980s, prior to installation of the current
waste mineral spirits storage system at the facility, used mineral spirits were placed into a 500-gallon
underground storage tank (UST) and then into a 10,000-gallon capacity UST. The 500-gallon UST provided
in -line solids settling for the waste mineral spirits prior to accumulation in the 10,000-gallon UST. The UST
system was operated for a five-year period from 1980 until its removal in August 1985. The waste mineral spirits
UST system constitutes the solid waste management units (SWMUs) that have been the focus of historical soil
and groundwater investigation activities.

will each be constructed of nested 1-inch diameter polyvinyl chloride (PVC) with screened
intervals of 15 to 18 feet bgs and 21 to 25 feet bgs. Note that the final screen intervals will be
determined in the field based on depth to bedrock but will not exceed a depth of 25 feet bgs. The
injection well screen will be 30 slot size and the filter pack will consist of pea gravel. The Phase
