RE: Pittsboro Mine
Mining Permit No. 19-16
Chatham County
Cape Fear River Basin
Dear Mr. Miller:
Your recent request to have the above referenced mining permit modified has been approved. The modification is
to update the monitoring well installation plan, modify stormwater control features, and add a condition for the
disposal of overburden/waste fines, as indicated in the application received August 7,2023, and the supplemental
information received November 27,2023. A copy of the modified permit is enclosed.
The conditions in the modified permit were based primarily upon the initial application. Modifications were made
as indicated by the modification request and as required to ensure compliance with The Mining Act of 1971. The
mine name and permit number shall remain the same as before the modification. I would like to draw your particular
attention to the following conditions where minor additions or changes were made: I11.4.E,I11.5.A,I11.1 LB,11I.12,
I11.13.F.
The issuance of a mining permit and/or any modification to it does not supersede local zoning regulations. The
responsibility of compliance with any applicable zoning regulations lies with you.
As a reminder,your permitted acreage at this site is 2184.4 acres and the amount of land you are approved to disturb
is 895.4 acres.
Please contact me at(919) 707-9220 if you have any questions.
Sincerely,

In accordance with the application for this mining permit, which is hereby approved by the Department of
Environmental Quality,hereinafter referred to as the Department,and in conformity with the approved Reclamation
Plan attached to and incorporated as part of this permit, provisions must be made for the protection of the
surrounding environment and for reclamation of the land and water affected by the permitted mining operation.
This permit is expressly conditioned upon compliance with all the requirements of the approved Reclamation Plan.
However,completed performance of the approved Reclamation Plan is a separable obligation, secured by the bond
or other security on file with the Department, and may survive the revocation or suspension of this permit.
This permit is not transferable by the permittee with the following exception: If another operator succeeds to the
interest of the permittee in the permitted mining operation,by virtue of a sale, lease, assignment or otherwise, the
Department may release the permittee from the duties imposed upon him by the conditions of his permit and by the
Mining Act with reference to the permitted operation, and transfer the permit to the successor operator, provided
that both operators have complied with the requirements of the Mining Act and that the successor operator agrees
to assume the duties of the permittee with reference to reclamation of the affected land and posts a suitable bond or
other security.
In the event that the Department determines that the permittee or permittee's successor is not complying with the
Reclamation Plan or other terms and conditions of this permit or is failing to achieve the purposes and requirements
of the Mining Act,the Department may give the operator written notice of its intent to modify,revoke or suspend
the permit,or its intent to modify the Reclamation Plan as incorporated in the permit. The operator shall have right
to a hearing at a designated time and place on any proposed modification, revocation, or suspension by the
Department. Alternatively,and in addition to the above,the Department may institute other enforcement procedures
authorized by law.
