Basically Vulcan plans to add two (2) railroad spurs to their existing railroad line. In adding these spurs, they also plan to extend an existing 42" pipe that is located under US 19/23 to accommodate these new spurs. The acreage to be modified on the existing permit is 2.3 acres. This amount needs to be added to plant area and removed from stockpile area. Please note that all current activities will continue within the existing permitted area. No new notification forms for adjacent property owners are necessary for this modification since this modification is adjacent to US 19/23. No new lands have been added, so the existing land entry agreement would be used. The vegetation plan as previously approved will remain in effect. Please note that the mine map consists of two sheets. Many of the minimum map requirements are not applicable or were included in the previous permit renewal package. Attached please find a check in the amount of $100.00 to cover the processing fee Tracy Davis, PE November 9, 1998 Page 2 We appreciate your attention to this request for modification and kook forward to approval.

ATIFAA, ®EHNf its review of the Vulcan Materials to the October 3, 1995 to November Quarry. It was found that Vulcan the blasting requirements of their All peak particle velocities, a measurement of ground vibration with units in .inches per second (ips), were well below the maximum allowable limit of 1.0 ips specified in Vulcan Materials Company's mining permit. More specifically, all recorded values were at or below 42 percent of the maximum limit of 1.0 ips. According to -extensive research by the U.S. Bureau of Manes and others, particle velocities below 0.5 ips effectively eliminate the possibility of any structural damage. All airblast readings, a measurement of the atmospheric - pressure wave (overpressure) with units in psi or dBL, were below the maximum allowable limit of 128 dBL specified in Vulcan Materials Company's mining permit and well below the U. S. Bureau of Mine's recognized level of 164 dBL for prevention of glass breakage. A key point worth noting is that glass breakage occurs at much lower levels of overpressure than structural damage, such as cracking plaster.

We discussed that the fill slope should be seeded as soon as practical to help control dust blowing to nearby homes. Several buildings (house, barn, outbuilding) will be torn or burned down and the residual material removed to an approved landfill before filling operations can begin. Basin #1 is shown as a rock check dam but, due to the disturbed area (7.7 acres) and watershed (15.6 acres), this probably should be revised to a perforated riser basin with adequately designed emergency spillway. The crossing of the small branch (at the end of ditch 2A) is shown with either a 24" CMP or rock crossing. Additional sediment controls may be needed below these structures.

Region Coordinator Habitat Conservation Program f DATE: June 20, 1994 SUBJECT: Application for mining permit modification by Vulcan Materials Company for Enka Quarry, Buncombe County, Mining Permit No. 11-03. Staff field biologists of the North Carolina Wildlife Resources Commission (NCWRC) have reviewed the mining permit modification application submitted by Vulcan Materials Company for the Enka Quarry in Buncombe County, and we are familiar with the project site. These comments are provided in accordance with certain provisions of the Mining Act of 1971 (as amended, 1982; G.S. 74-46 through 74-68; 15 NCAC 5) and the North Carolina General Statutes (G.S. 113-131 et seq.). The applicant proposes to use a 18-acre site already included on the mine permit as a disposal area for overburden. Erosion control measures will include riprap ditches, sediment basins, and silt fencing. The NCWRC does not object to this permit modification, provided the following recommendation is implemented by the applicant: Plant species that benefit wildlife by providing food and cover should be added to the regular seed mixture to stabilize areas where overburden and tailings are deposited.

Enderle, P.E. Enderle Engineering 46 Haywood Street, Suite 201 Asheville, North Carolina 28801 Project No. 023794 MIDEAST DIVISION t I l 1 r,,,,, ,,•�� CA RQ�,•., �q4 Gry • . -i� ; Q � = '• FNCENEf� �, NARRATIVE The site for the proposed 1994 land filling operation is a portion of the Vulcan Materials Company property off U.-S. 19 & 23 in Enka, N.C. Specifically, it is in the southernmost portion of the Vulcan property, bounded on the south, east and west by Queen Road and several private properties, and on the north by Vulcan's main quarry operations. Portions of the site are currently in woods and pasture and portions are bare. The topography indicates that fill materials have been placed on portions of the site previously. Materials to be used for the fill will be obtained by stripping overburden from a site at the south edge of the current pit. Reference is made to Enderle Engineering Drawing No. 023794-01C for the relative locations of the areas to be affected by these operations. After removal of overburden, the stripped area will be used to expand the rock quarry. After completion of mining activities, the quarry area will eventually become a lake and other affected areas will be treated as required by the Approved Reclamation Plan contained in the operating permit for this quarry. Both the area to be stripped of overburden and the area to be filled are located within the boundary of the original mining permit and approval of the proposed operations is sought as a modification of the current operating permit. An undisturbed buffer of 25' or more will be. maintained on the south, east and west, between disturbed areas and adjacent private properties. The site is adjacent to the area to be stripped and there should be no danger of off -site tracking of earth by equipment. For calculation purposes, the Main Fill has been divided into two areas; Main Fill -West and Main Fill -East. The dividing line coincides with the existing 'ridge line' of the previous fill. This ridge line, extended to Queen Road, also marks the division of off - site storm drainage into two drainage swales, one trending northeast and the other northwest. Both of these swales end in depressions in the topography at approximate latitude N 6000, from which points the discharge is conveyed by existing pipes to other areas of the quarry property. Much of the area around the eastern drainage swale is wooded and a residential community of mostly mobile homes is located adjacent to the property line. Therefore, the proposed fill has been held well back from the property line in this area. As much as possible, runoff from proposed fill areas is directed away from this drainage Swale and it is left undisturbed. Narrative Project No. 023794 April 20, 1994 Page 2 On the west side of the main fill area, the existing pipe is covered by a moderate amount of fill and discharges into a long ditch that will receive up to 60' of new fill. Because of the length of pipe that would be required here and tailwater from the proposed Drainage Basin No. 1, outlet conditions control the design of the pipe. A 36" diameter CMP would be required for a 25 year design storm. Approximately 500 l.f. of new pipe would be required, with an additional 200 l.f. if the existing pipe is determined to be not suitable for continued use under the higher fill. Because of the length of pipe and the high fill, an open cut is preferred for conveyance of the storm drainage from the existing depression to the proposed new drainage basin. The pipe is shown on the Erosion Control Plan as an alternative to the open cut if severe rock problems should be encountered in the excavation for the open cut, It is proposed to use the existing graded surfaces as much as possible for a haul route from the area to be stripped to the Main Fill area. This sloped bench will also allow for installation of two protected ditches to intercept most of the runoff from the new fill areas. This runoff will be directed to Drainage Basins Nos. 1 and 2. The only proposed fill area not draining into one of the protected ditches will be the East Side Fill, if constructed. A silt fence is proposed along the base of this fill to trap sediment. Following are descriptions of various elements of the erosion control plan. Drainage Basin No._1_ This basin will receive runoff from off the site as well as potentially sediment -laden runoff from the proposed fill and from the open cut (ditch 1). It is estimated that approximately 7.7 acres of disturbed area will drain to this basin and runoff will be received from an additional 15.6 acres for a total of slightly over 23 acres. It is proposed to form this basin by constructing a rock dam across the existing ditch below the toe of the fill and the outlet of proposed ditch No. 1. Reference is made to sheet No. 3 of the drawings for additional details. Drainage Basin No. 2 This basin will not receive off -site runoff but will only receive potentially sediment -laden runoff from about 2.9 acres. This basin will be constructed on and in existing soil materials with a rock dam for control and possible excavation to form a portion of the basin. Reference is made to sheet No. 3 of 'the drawings for more details on this basin. Narrative Project No. 023794 April 20, 1994 Page 3 Silt Fence Construction of the East Side Fill, if used, will result in a disturbed area of about 0.5 acre. The area below the toe of this fill is fairly level and installation of approximately 400' of silt fence is proposed to intercept any sediment from the fill. Protected Ditches Three ditches are proposed along the toe areas of the new Main Fill. With moderate slopes and low volume of runoff, protection of most sections of these ditches can be provided with Class A Stone for Erosion Control. The lower portions of ditches 1A and 1B may require some Class B stone if experience proves that the Class A is not sufficient. Temporary failure of the lining and erosion of the ditches will not result in off -site sedimentation. Ditch No. 2 has an average slope of about 2% and may be protected with grass if preferred over stone.

Please discard my previous letter and replace it with this corrected letter. This letter is in response to Mr. Julian McClellan's letter dated June 2, 1994 to Mr. Richard Phillips, Asheville Regional Engineer, Land Quality Section, regarding the production shot that occurred on Wednesday, June 1, 1994. An air overpressure measurement of 129 dbl was recorded by your company's seismograph for this blast. This office has reviewed the investigation report prepared by Mr. Gene Laughrun, Technical Representative with Austin Powder Company, dated June 2, 1994 as well as the other supporting documentation submitted with Mr. McClellan's letter. I concur with the recommendations outlined in .Mr. Laughrun's report. The recommendations pertain to the following: 1) Evaluation of face conditions and rock conditions in thinly burdened areas, in addition to the stemming region, to insure that excess venting of explosive gas does not take place. 2 ) Use of smaller diameter explosives, 3 to 3 1/2 inches, to further lower the pounds of explosives per foot of each borehole. ` Geological Survey Section Lane!

Julian McClellan Vulcan Materials Company..-- P. 0. Box 549 Enka,.' N. C. 26728 Dear Julian: This letter is in reference to a high reading on peak air pressure registered on a shot made Wednesday,, June 1, 1994. Wednesday's shot was loaded on the top level of the pit on the west side where there is an expansion of the pit being made. All the shots in this area are for the ex- press purpose of stripping the over burden from the clean stone. The shot in question was a combination of sap rock and clean production rock. Due to the mixture of the two types of material the face of the shot was ragged and fractured. It has been difficult to get a good solid face because of the integrity of the rock formations. In surveying the face before loading I found five holes along the face that had 12' to 14' of burden at the toe and ranging to 8' at the top. These particular holes were bottom loaded with ANFO up to 18'-20' where at that point the burden began to get thin. In order to lower the pounds Per foot up the remainder of the column four inch diameter sticks were placed up to 10', where our stemming began. By using four inch diameter material the column load was reduced from 11.5 lbs. to 5 lbs. per foot, in hopes that this would compensate for,the thinner -burden. Upon intiation of the shot it was observed that there was some flyrock which appeared to come off of the front of the shot. The flyrock was not excessive, but was a little _more than usual. It is estimated that it traveled approximately 125-450 feet, well inside the guarded area and did not leave the pit. - r After viewing the video it is nay conclusion that there was a blowout in the area of the five holes which had a thin burden. The airblast has been generated by explosive gases being vented through the factures in this thin burdened area of the face. irp 4V�'4��� yE AUSTIN POWDER COMPANY 430 GOLnviEw RD.

Fullwood, Executive Director MEMORANDUM TO: Tony Sample, Assistant Mining Specialist Land Quality Section FROM: Stephanie E. Goudreau, Mt. Region Coordinator Habitat Conservation Program DATE: November 8, 1993 SUBJECT: Application for mining permit modification by Vulcan Materials Company for Enka Quarry, Buncombe County; Mining Permit No. 11-03. Staff field biologists of the North Carolina Wildlife Resources Commission (NCWRC) have reviewed the mining permit modification application submitted by Vulcan Materials Company for the Enka Quarry in Buncombe County, and we are familiar with the project site. These comments are provided in accordance with certain provisions of the Mining Act of 1971 (as amended, 1982; G.S. 74-46 through 74-68; 15 NCAC 5) and the North Carolina General Statutes (G.S. 113-131 et seq.). The applicant proposes to use a 22-acre site already included on the mine permit as a disposal area for overburden. An undisturbed buffer of at least 200-feet wide will be maintained to the north of the site along Hominy Creek. Erosion control measures will include sediment basins and riprap channels. The NCWRC does not object to this permit modification, provided the following recommendation is implemented by the applicant: Plant species that benefit wildlife by providing food and cover should be added to the regular seed mixture to stabilize areas where overburden and tailings are deposited. Suggestions include: Early spring: Switchgrass 8 lbs/acre VA 70 shrub lespedeza 20 lbs/acre a Fall: Rye grain 30 lbs/acre Orchard grass 18 lbs/acre White clover 5 lbs/acre Thank you for the opportunity to review and comment on this project.

PLAN PERM11 NO, 11-3 Prepared for VULCAN MATERIALS COMPANY MIDEAST DIVISION Joseph J. Enderle, P.E. Enderle Engineering 46 Haywood Street, Suite 201 Asheville, North Carolina 28801 Project No. 018893 _ 0 NARRATIVE 0 The site for the proposed 1993-94 land filling operation is a portion of the Vulcan Materials Company property off V.S. 19 & 23 in Enka, N.C. Specifically, it is in the western portion of the Vulcan property, bounded on the west by WNC Pallet Co. property, on the north by Hominy Creek, and on the east by Vulcan's main quarry operations. Portions of the site are currently in woods and pasture and portions are bare. Materials to be used for the fill will be obtained by stripping overburden from a site at the west edge of the current pit, in the southeastern part of the property. Reference is made to Enderle Engineering Drawing No, 018893-01C for the relative locations of the areas to be affected by these operations. After removal of overburden, the stripped area will be used to expand the rock. quarry. After completion of mining activities, the quarry area will eventually become a lake and other affected areas will be treated as required by the Approved Reclamation Plan contained in the operating permit for this quarry. Both the area to be stripped of overburden and the area to be filled are located within the boundary of the original mining permit and approval of the proposed operations is sought as a modifigation of the current operating permit. An undisturbed buffer of 200, or more will be maintained on the north, between the fill site and Hominy Creek. The site is more than 1500 ft . from a public road, and there is no danger of off -site tracking of earth by vehicles. Bol. Dam No. 1 A Rock dam will be constructed at approximately N 7950, E 9750. All water from disturbed areas above this, about 9.25 acres, will be directed to the basin before leaving the site. Rock Dam No•. _2 A rock dam will be constructed at approximately N $400, E 8100. Water from two disturbed areas will be directed to the trap. The first is a 3 acre area on the west slope of the disposal area; the second is on the north slope and will have 4.05 acres of disturbed soil. The trap is located down the slope. This location was chosen because of the steep slopes at all other locations. By turning the long dimension of the trap parallel with the creek it is possible to get the proper length to width ratio for the basin. Bguins An inlet in will be constructed on the north slope to divert water from the rip rap channels to the 24" corrugated metal pipe, which empties into the sedimentation basin behind rock dam No. 2 mentioned above. RiQrag h nnel Riprap channels will be constructed to prevent channel erosion and to transport water to erosion control structures. See detail sheet for dimensions. Outlet Stabilization A rip rap apron will be located at Hominy Creek at the outlet of the 24" pipe to prevent scour. Fill slopes will be constructed at 2:1 with fill depths as much as 75 feet. Fill will be placed in layers not to exceed A inches in depth and compacted. Greater thickness of layers may be used where the fill is essentially rock and soil is absent or present in very small quantities. Silt volumes are calculated' at a rate of 1800 CF/acre/year, as recommended by the N.C. Erosion and Sediment Control Planning and Design Manual.
