Re: Alternative Cover Material Demonstration Authorization Letter
Gaston County Landfill — Permit #36-06
Proposed ACM: Posi-Shell
Dear Ms. Smith:
Dee Freeman
Secretary
This letter is in response to your request for approval to demonstrate the capability of an Alternative Cover
Material (ACM) at the referenced landfill. This Authorization Letter conditionally approves the Demonstration
Project as described in the letter submitted by you on April 13, 2010 for a period of Eight (8) months. This
period of time provides the operator with six (6) months of time to perform the Demonstration Project, and 60
calendar days to compile and submit the certified Demonstration Report to the Solid Waste Section for review.
The demonstration period will expire on December 26, 2010.
The ACM must comply with 15NCAC .I626(2)(b) which requires the Operator to demonstrate that the ACM
will control disease vectors, fires, odor, blowing litter, and scavenging without presenting a threat to human
health and the environment. The ACM shall be applied and inspected as detailed in Section 4.0 of the
"Performance Evaluation and Demonstration Procedures".
The demonstration period does not allow for or give exemption to the requirements for Daily Cover. If the use
of the product is not sufficient for daily cover, it should not be used. It is the operator's responsibility to ensure
an adequate cover is being provided. The use of the ACM must be discontinued if it does not perform as well as
soil in the areas of fire prevention, vector control, blowing waste prevention, odors, and scavenging.
For this demonstration, the use of Posi-Shell is not approved for application on external slopes.

After six (6) months of using the conditionally approved ACM, the facility operator may then either:
(1) within 60 calendar days provide a certified Demonstration Report demonstrating the feasibility to
request approval for the use of the ACM on a full-time basis, or
(2) cease use of the ACM, properly dispose of any remaining ACM, and provide a Closure Letter
detailing the findings of the use of the material during the approval period and what actions were
taken to dispose of the material.
The certified Demonstration Project report must be signed by the operator and certified by a professional
engineer licensed in North Carolina. The report shall include documentation addressing the performance and
effectiveness of the material, the number of times the ACM was used, the quantities of the ACM, and other
supportive information, including photographs.
Following satisfactory demonstration of the ACM and application, the Solid Waste Section may issue a Permit
Modification for the facility that includes the ACM operation.
Please note that the continuation of the use of this ACM is performance based. Should the application of the
ACM become impracticable or contribute to conditions hazardous to public health, safety or the environment,
the operator is responsible for immediately terminating the ACM use and applying compacted earthen material
cover in accordance with the Solid Waste Rules. Impracticable conditions are conditions that make the
placement of ACM difficult due to adverse climate such as rain, wind, or frozen precipitation, or other
conditions that adversely affects the ability of the ACM to meet the Performance Standards. The operator must
maintain a ready stockpile of earthen material cover material and the equipment necessary to apply the earthen
material cover to respond to an adverse situation. Therefore, approval of the continued use of the ACM may be
revoked at any point in time by the Division.
Please notify me when the demonstration project begins. If you have any questions, please call me at (704)
235-2144 at the Mooresville Regional Office.
Sincerely,
Charles T. Gerstell
