The modification is to reclassify area for a concrete plant tenant and reclassify an undisturbed buffer for an entrance as indicated on the mine maps received on April 13,2021 and additional information received on January 19,2021 and April 13,2021. The modification includes reclassifying a 6-acre area for a tenant to install a concrete plant. The proposed area is located in the northeast corner of the property,just north of the existing tenant site utilized as an asphalt plant. 6 acres will be removed from the"Other-buffers,wetland,etc."category and then added to the"other affected acreage —Asphalt Plant, Concrete Plant, etc."category. This modification will also reclassify a 50 ft x 440 ft undisturbed buffer as and unexcavated buffer, so that an entrance road to the proposed tenant concrete plant can be installed between the existing fence line and existing 25 ft. high berm.). 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. 1 would like to draw your particular attention to the following conditions where minor additions or changes were made: I11.2.C, 111.2.D, II1.3.C, 1I1.43, III.13.i, I11.20.C, II1.20.1), IV, VILB, VII1.3. 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 485.76 acres and the amount of land you are approved to disturb is 233.9 acres. Please contact me at(919)707-9220 if you have any questions.

Excessive Ground Vibration/Air blast Reporting: If ground vibration or Air blast limits are exceeded,the operator will immediately report the event with causes and corrective actions to the Department. Use of explosives at the blast site that produced the excessive reading shall cease until corrective actions approved by the Department are taken. However, blasting may occur in other approved areas within the permitted boundary. Authorization to blast at the blast site may be granted at the time of the verbal reporting of the high ground vibration or high air blast reading if the circumstances justify verbal approval. Failure to report will constitute a permit violation. 15. Flyrock Prevention: The operator shall take all reasonable precautions to ensure that flyrock is not thrown beyond areas where the access is temporarily or permanently guarded by the operator. Failure to take corrective measures to prevent flyrock and repeated instances of flyrock shall be considered a violation of the Mining Permit. 16. Flyrock Reporting Should flyrock occur beyond the permitted and guarded areas,the operator shall immediately report the incident to the Department. Further use of explosives on the mine site shall be suspended until the following actions have been taken: i. A thorough investigation as to the cause(s)of the incident shall be conducted. ii. A report detailing the investigation shall be provided to the Department within 10 days of the incident. The report shall,at a minimum,document the cause(s)of the incident along with technical and management actions that will be taken to prevent further incidents. The report shall meet with the approval of the Department before blasting may resume at the mine site. 17. Studies: The operator shall provide to the Department a copy of the findings of any seismic studies conducted at the mine site in response to an exceedance of a level allowed by these blasting conditions. The operator shall make every reasonable effort to incorporate the studies' recommendations into the production blasting program. Page 9 18.
