By this letter, we wish to notify you ofour intentions to begin an exploration drilling program on the property on or about March 14, 2019, continuing through approximately the end of March. Our planned exploration drilling will utilize a rotary percussion crawler-mounted drill. Our intention is to minimize disturbance to the land surface by traversing the site via hand prepared trails. We do not anticipate the need for mechanized land disturbing activities at or exceeding the one acre threshold provided for in the Sedimentation Pollution Control Act of 1973. As such, it is our understanding that no Erosion and Sedimentation Control Plan Plan) is required for this activity. Should the need for greater than one acre of land disturbing activities become apparent as the drilling program progresses, we will halt drilling operations and submit an Plan for your review prior to exceeding the one-acre threshold. Land disturbing activities would not resume until an Plan approval has been issued. Regardless of the extent of land disturbance, we will install temporary measures as necessary to protect nearby watercourses and neighboring properties. Mr. Toby Vinson March 5, 2019 Page 2 am available to answer any questions or receive any comments you or your staff may have concerning our project. I may be reached via phone at either of the numbers provided in the cover email. Should a site visit by DEMLR staff be necessary or appropriate during the drilling program, please contact me via the cell phone number provided as the property will be secured by a locked gate. Sincerely, Wake Stone Corporation a?me, Geologist/Environmental Supervisor
