As you know, Macon County is being required by the North Carolina Division of Solid Waste Management (NCDSWM) to improve the final cover system on the Old Franklin landfill, and provide supporting documentation regarding cap thickness and permeability. Our previous letter proposed a series of tasks necessary to accomplish this goal. As of this date, the County has conducted the geotechnical sampling to determine soil permeability at the landfill and potential borrow areas. The original timeframe for completing all the work was projected to be October 1, 1995. As you may know, the County has also been actively involved in addressing groundwater contamination problems at both the closed Franklin and Highlands landfills. They recently completed and submitted a comprehensive remediation plan outlining future work on both landfills. Unfortunately, monies originally budgeted for the Old Franklin landfill capping had to be diverted to complete the remediation plan. On behalf of Macon County, McGill Associates requests a three (3) month extension of the original completion date to January 1, 1996. The County intends to authorize additional funds and complete the capping work by that date. P.O.

As you know, because this landfill received waste after October 9, 1991, it ulust have a final cover system which meets the criteria outlined in 15A NCAC 13B .1627(c)(1). A recent review of the closure documentation submitted by Cranston, Robertson, and Whitehurst on the County's behalf indicates that the cover system as installed does not meet these criteria. The Solid Waste Section is asking that Macon County propose a schedule outlining measures to remedy this situation. Additionally, it is our understanding that there is a need for maintenance at this site to prevent the impoundment of water over waste. This issue should be included in the schedule and should be addressed as soon as is practical. For further discussion of this matter, please contact me at (910) 896-7007, or Jim Patterson at (704) 251-6208. Sincerely, Janis D.

Dear Mr. Carpenter, The following are comments and questions which were generated by the Solid Waste Section (Section) during the review of the water quality assessment plan submitted by Pin -Point Environmental Services, Inc. (Pin -Point), on behalf of Macon County. If it was required, responses to the following questions and comments were provided by Pin -Point Environmental Services, Inc. during teleconference discussions on November 22. 1) In conjunction with the proposed fracture trace analysis, information is needed on the local and regional geology. In order to develop an understanding of the geology and the controlling features of the hydrogeology at the site, the inclusion of pertinent information from local and regional geology studies, previous site investigations, professional papers, geologic surveys, etcetera, is necessary. Response: Pin -Point intends to conduct a search for any available information, including contacting the N.C.G.S. office in Asheville for additional data. 2) Are any landfill preconstruction or construction records available which has information about types, nature and thickness of the soil, the partially weathered rock zone, the bedrock, depth of cell excavation, etcetera? Response: Nothing was discovered during the initial search for information. However, further attempts will be made to ascertain if such data exists. P,O.

Response: Again, nothing was discovered during the initial search for information and further attempts will be made to ascertain if such data exists. County employees who .x,- -d- atthe-landfills--may-be-able to provide-additionatW-enn-ation-abotit types of waste and specific locations where particular waste were disposed. 4) Construction records of private supply wells in the vicinity of the landfill will be needed to evaluate potential avenues of ground water degradation. The Section requests that this information be provided in an interim report so that it can be utilized in the Phase I activities. A March 1, 1996 due date for the interim report is necessary to allow for review of the data and evaluation of possible beneficial modifications to the proposed Phase I activities. Response: The County will comply with this request and Pin -Point will immediately begin to collect this information. 5) Please submit the private well sampling program, including the following details: a) sampling frequency b) constituent list and methods used c) summary of past data and constituents tested for The Section requests that this information be provided in the interim report. Response: The County will comply with this request and Pin -Point will immediately begin to collect this information. 6) Please include the results of any landfill cap investigations/evaluations and proposed improvements, if any. The Section. requests that this information be provided in the interim report. Response: Pin -Point will begin collecting this information and will conduct investigations to provide the necessary data. 7) Please include any available monitoring well construction and boring logs. Any other boring logs pertaining to previous site investigations should also be included. This will facilitate the development of the cross -sections and will enhance the understanding of the hydrogeology of the site. This information should be very useful in determining future monitoring well locations. 8) Page 5, Section "Old Franklin Landfill Monitor Wells Rationale (Figure 1)", first paragraph; if the hydrogeologic environment is different than what is anticipated (i.e. shallow bedrock), have alternate drilling plans been considered? Response: Monitoring wells screened in the bedrock will not be installed in the first phase of the assessment. The intent of installing nested pairs during the first phase of the assessment is to screen the shallow well across the water table and screen the deeper well across the partially weathered rock zone just above bedrock. If bedrock is encountered beneath the water table at a shallower depth than is anticipated the Project Geologist will make the decisions on vertical placement of the screens. If significant changes to the approved plan become necessary the Section will be consulted before implementation. 9) Page 6, section "Monitor Well Construction"; thorough cleaning of drilling equipment is required prior to boring activities and between each boring. Response: Pin -Point agrees. A maximum screen length of fifteen feet is the Section policy. Deviations from this policy must be justified to and approved by the Section prior to installation. Based upon the depth of the proposed monitor wells the gravity method of grouting the wells is not permissible. Further explanation is needed on the proposed screen length on page 7, fourth paragraph. Response: The 2.5_foot screen length was proposed to be used in areas where DNAPL (dense non -aqueous phase liquids) are suspected. This screening technique is designed for sampling a discrete interval just above bedrock without providing communication with deeper zones. All future monitoring wells should be constructed according to the standards set forth in the N. C.A. C., Title 15A, Subchapter 2C, Section. 0100, Well Construction Standards and the North Carolina Water Quality Monitoring Guidance Document For Solid Waste Facilities. 10) Page 8, section "Aquifer Testing", second paragraph; slug -in tests should only be utilized in monitoring wells where the well screen and sand pack are entirely below the water table. If the water table falls below the top of the sand pack the volume added would flow out of the well into the vadose zone resulting in an overestimation of the hydraulic conductivity. For more information refer to DEM's technical policy concerning slug tests and their revision letter dated October 6, 1995. 11) Page 9, first paragraph; what sampling equipment will be decontaminated in the field? Disposable Teflon® bailers, referenced in the third paragraph, should come from the I , . manufacturer with certification that they have been laboratory cleaned. In the second paragraph, what kind of pump will be used to purge the monitoring wells and at what flow rates? Response: The water level indicator will be decontaminated in the field. Disposable Teflon® bailers which are certified laboratory cleaned will be used. A variable speed (0 to 9 gp ) —run s& pump may he. utilizedsn_p_urging_the -monitoring wells with high volume water. The pump will be positioned such that it is pumping water from near the top of the water column. As the water level fluctuates, the pump is raised or lowered to maintain its position near the top of the water column. The pumping rate will be adjusted to be compatible with the rate at which formation water is introduced to the well, thereby reducing the possibility of contaminant volatilization and the increasing of turbidity in the well space . 12) Page 10, "Evaluation and Conclusions", second paragraph; the Section recommends cross -sections, potentiometric maps and a conceptual model of the sites be developed based on all available data before installation of proposed monitoring wells. The above can be a very useful tool in understanding the hydrogeology and placing monitoring wells in the most beneficial horizontal and vertical locations at the site. Flow nets can be developed to aid in determining if the monitor wells are intersecting flow, both horizontal and vertical, from the landfill. All the above can be updated as additional data is acquired. The Section requests that this information be provided in the interim report. 13) Laboratory quality assurance/quality control program; the Section requires water quality sample analysis by a laboratory certified by the Division of Environmental Management for groundwater analysis (15A N.C.A.C. 2H .0800). The laboratories used for water analysis for solid waste management facilities shall be certified under the Division of Environmental Management Certification program for the approved methods and at the approved levels of certification. Data from laboratories that do not have the appropriate certification or did not use specified test methods will be deemed unacceptable. Field and laboratory personnel should be informed that unfiltered water samples are required by the Section. Filtered samples may be collected for comparison purposes but that is in addition to unfiltered samples. 14) Page 10; minimum frequency for sampling is twice per year. 15) The analyte lists for plume tracking and evaluation referenced in the last paragraph on page two are negotiable. If documentation can be presented which demonstrates alternative parameters would be more beneficial in plume delineation and evaluation the Section will evaluate a modified plan. 16) Before the initiation of the proposed phase II it will be necessary to submit an interim r• ? report which discusses the findings and conclusions of phase I before approval of phase II activities. The consultant and/or the Section may amend the phase II plan at that time. 17) Locations of the surface water sampling points need to be established and identified on the maps in future reports. The surface water sample locations should be permanently marked in the field to insure future samples are consistently taken from the same locations. Surface water samples should be taken each time the monitoring well system is sampled. 18) A Health and Safety Plan for field operations is required before plan approval can be given. More information is required on the "Special drilling procedures and protective gear" mentioned on page 2. Response: A health and safety plan will be provided which will include the above requested information. Based on the conversation that took place during our November 22 teleconference it is the Section's understanding that this letter serves as an amendment to the water quality assessment plan submitted on behalf of Macon County by Pin -Point Environmental. The modifications and additions to the plan included in this correspondence shall be considered part of the approved phase I assessment plan. In the future two copies of progress reports and/or additional assessment phase plans will be sufficient. Concurrence with this letter serves as plan approval and implementation of assessment activities can begin immediately.

Dear Mr. Carpenter, Water quality data from past sampling of the ground -water detection monitoring wells at the closed Franklin and Highlands County Sanitary Landfills indicates levels of chemical constituents exceeding the water quality standards for various organic constituents. In order to more clearly identify the type, degree and extent of ground -water contamination pursuant to N.C. Administrative Code 13B additional assessment of the ground and surface water quality will be necessary. The purpose of this letter is to present the State's overall performance objectives and to outline the roles of the County and State in pursuing the water quality investigations. The County should acquire the services of a N.C. licensed professional geologist with experience in assessment and remediation of ground water contamination and within ninety (90) days submit a plan for each site that addresses the objectives listed below. (a) The nature and concentration of the contamination in the ground and surface waters. (b) The horizontal and vertical extent of contamination ("the plume") and the direction and rate of migration of the plume in the ground water. (c) The source(s) of contamination detected in ground and surface water. (d) Potential ground and surface water receptors that could be affected by migration of the contamination. P.O.
