The following documents are enclosed to support the Application (2 copies of each(:
• Application for NCG020000 coverage for proposed dewatering activity.
• $120 permit Processing Fee
• Copy of submitted NCDEQ DEMLR Mining Permit Application
• Copy of submitted NCDEQ DWR Registration Application for Water Usage.
• Mine Map and Reclamation Map
• Adjoinder Notification Map
• USGS Quad Site Map
• Pitt County Stream Determination for applicability to Tar-Pamlico Riparian Area Protection
We respectfully ask for your review of the above-listed enclosures as they support the requested mining

Permit
Varun,
Hope you are doing well. I am working on an application for one mining site that is requesting an NCG02 permit to
de-water the excavation,and I am notifying you regarding the POM plan and State Stormwater Permit as required
In the NCG02 application. Location information is as follows:
• New mining permit, application to be submitted shortly,Alvin Road Mine(14.69-acre excavation),
Grimesland, NC, Pitt County—New permit with dewatering, POM plan will be submitted with NCG02
application,there are no plans for any impervious surfaces on the property beyond that of a temporary
portable office(10'x 24% 1 do not believe a State Stormwater Permit will be required.
Please let me know if you have any questions or comments.
Thank you,
