POST OFFICE BOX 130 SANFORD, NORTH CAROLINA 27331 Subject: Permit No. WQ0030580 Earthtec of NC, Inc. Earthtec Environmental Bioremediation Facility Chatham County Dear Mr. Keller: In accordance with your permit application received on October 16, 2004 as well as the additional information received on August 24, 2006; September 20, 2006; and October 13, 2006; we are forwarding herewith Permit No. WQ0030580 dated March 30, 2007 to Earthtec of NC, Inc. for the operation of residuals processing facility and Class A EQ residuals product generation/land application program. The product is generated through a composting process at Earthtec Environmental Bioremediation Facility and meets all Class A requirements as stipulated under 40 CFR Part 503. This permit is being issued to approve the operation of the Class A EQ residuals product production/land application program for a five-year cycle. This permit shall be effective from the date of issuance until February 28, 2012. Please take time to review this permit carefully and become thoroughly familiar with various permit conditions. As always, pay particular attention to the monitoring and reporting requirements, as failure to establish an adequate system for collecting and maintaining the required operational information will result in future compliance problems. Of special interest to you are the following items: ♦ The approved residual sources listed in Appendix A include all the residual sources that were approved with this issuance of the permit. In the future, the Permittee shall submit a permit renewal/modification application package with a separate list of residuals sources to be added to or dropped from the program during permit renewal or modification. ♦ Condition II.4 requires that all waste, Class A EQ residuals product, and processed residuals shall be adequately stored to prevent leachate runoff prior to and following treatment. Following treatment, Class A EQ product may be stored in an elevated silo, placed on a concrete pad, kept under shelter, or stored on top of sludge compost pad until such time as it is distributed to the user or applied to land. If an alternative storage site is to be used, approval shall first be obtained from the Division.

All reports and documentation (GW -1, GW -59) shall be mailed to the following address: NCDENR-DWQ Information Processing Unit 1617 Mail Service Center Raleigh, NC 27699-1617 Updated blank forms (GW -1, GW -59) may be downloaded from the Aquifer Protection Section's website at http://h2o.enr.state.nc.uslaps/gpu/forms.htm or requested from the address mentioned above. b. For the initial sampling of the well(s), the permittee shall submit a copy of the GW -1 Form (Well Construction Record) with the Compliance Monitoring Form (GW -59) for each well to the address listed in the "Reporting / Documentation" section of the Groundwater Requirements. Initial Compliance Monitoring Forms that do not include copies of the GW -1 form may be returned to the permittec without being processed. Failure to submit these forms as required by this permit may result in the initiation of enforcement activities pursuant to NC General Statutes 143-215.6A. c. The results of the sampling and analysis must be received on Form GW -59 (Groundwater Quality Monitoring: Compliance Report Form) by the Aquifer Protection Section (address listed in the "Reporting / Documentation" section of the Groundwater Requirements), on or before the last working day of the month following the sampling month. The data of all groundwater sampling and effluent sampling analyses required by the permit conditions must be reported using the most recent GW -59 form along with attached copies of the laboratory analyses. 9 d. Within sixty (60) days of completion of all monitoring well(s), the Permittee shall submit two original copies of a scaled site map (scale no greater than 1 "=100'); however, special provisions may be granted upon prior approval for large properties, The map(s) must include the following information: i.

The Compliance Boundary for a disposal system individually permitted after December 31, 1983 shall be established at either (1) 250 feet from the waste disposal area or (2) 50 feet within the property boundary, whichever is closest to the residuals composting facility. An exceedance of groundwater quality standards at or beyond the Compliance Boundary shall be subject to immediate remediation action according to 15A NCAC 2L .0106(d)(2). b. The REVIEW BOUNDARY shall be established around the residuals composting facility midway between the Compliance Boundary and the perimeter of the waste disposal area. Any exceedance of groundwater quality standards at the Review Boundary shall require action in accordance with 15A NCAC 2L.01 06(d)(1). Other Requirements: a. Any groundwater quality monitoring, as deemed necessary by the Division, shall be provided. Al V. INSPECTIONS 1. The Permittee or his designee shall inspect the residuals processing facility as well as the facilities related to the Class A EQ residuals product land application (or distribution) program to prevent malfunctions and deterioration, operator errors and discharges which may cause or lead to the release of wastes to the environment, a threat to human health, or a nuisance. The Permittee shall maintain an inspection log or summary including at least the date and time of inspection, observations made, and any maintenance, repairs, or corrective actions taken by the Permittee, This log of inspections shall be maintained by the Permittee for a period of five years from the date of the inspection and shall be made available to the Division or other permitting authority, upon request. 2. Any duly authorized officer, employee, or representative of the Division may, upon presentation of credentials, enter and inspect any property, premises, or place on or related to the residuals processing facility or Class A EQ residuals product land application (or distribution) program at any reasonable time for the purpose of determining compliance with this permit; may inspect or copy any records that must be kept under the terms and conditions of this permit; and may obtain samples of groundwater, surface water, or leachate. V. GENERAL CONDITIONS This permit shall become voidable unless the residuals processing facility and Class A EQ residuals product land application (or distribution) program are operated in accordance with the conditions of this permit, the supporting materials, and in the manner approved by the Division. 2. This permit shall be -effective only with respect to the nature and volume of residuals described in the application and other supporting data. Failure to abide by the conditions and limitations contained in this permit may subject the Permittee to an enforcement action by the Division in accordance with North Carolina General Statutes § 143-215.6A through § 143-215.6C. 4. The annual administering and compliance fee shall be paid by the Permittee within 30 days after being billed by the Division. Failure to pay the fee accordingly may cause the Division to initiate action to revoke this permit, as specified by 15 NCAC 2H .0205 (c)(4). The issuance of this permit does not preclude the Permittee from complying with any and all statutes, rules, regulations, or ordinances that may be imposed by other government agencies (i.e., local, state, and federal) which have jurisdiction, including, but not limited to, applicable river buffer rules in 15A NCAC 2B .0200, soil erosion and sedimentation control requirements in 15A NCAC Chapter 4 and under the Division's General Permit NCG010000, and any requirements pertaining to wetlands under 15A NCAC 2B .0200 and 15A NCAC .0500. 6.

The Permittee, at least six months prior to the expiration of this permit, shall request its extension. Upon receipt of the request, the Division shall review the adequacy of the residuals processing facility and Class A EQ residuals product land application (or distribution) program described therein, and if warranted, shall extend the permit for such period of time and under such conditions and limitations as it may deem appropriate. This permit shall not be automatically transferable. In the event that there is a desire for the residuals processing facility and Class A EQ residuals product land application (or distribution) program to change ownership or to change the name of the Permittee, a formal permit request shall be submitted to the Division documentation from the parties involved and other supporting materials as may be appropriate. The approval of this request shall be considered on its merits and may or may not be approved, Permit issued this the thin' th day of March, 2007 NORTH CSR A ENV NTAL MANAGEMENT COMMISSION .r s for Alan W.
