Box 85A Cumberland, ME 04021 Tel: 207.829.5016 • Fax: 207.829.5692 info@smemaine.com smemaine.com Subject: Evaluation Report of Slope Pin and Piezometer Monitoring Data Ash Landfill Glatfelter Pisgah Forest, NC Dear Ms. Aja Consistent with Sevee & Maher Engineers, Inc.'s (SME) letter to the North Carolina Department of Environmental Quality (NCDEQ) (i.e., letter to D. Aja) dated July 9, 2019, Glatfelter has been performing routine monitoring of nineteen slope pins and eleven piezometers at the Ash Landfill in Pisgah Forest, North Carolina. The monitoring was instituted in mid -May 2019 to address possible landfill movement as identified from previous monitoring of several of those same instruments. This letter addresses monitoring data collected for October 2019. The slope pin monitoring consists of determining the horizontal (i.e., northing and easting) and vertical (i.e., elevation) position of each pin by way of ground survey. Monitoring of the piezometers consists of measuring the depth to water in each piezometer and calculating the water elevation based on a previous elevation survey of the piezometer pipe openings. Figure 1 shows the location and identification of each of the slope pins and piezometers monitored. Survey control for the slope pin and piezometer monitoring is based on permanent control points, which are located near the Ash Landfill perimeter, but outside of the waste limit. The horizontal and vertical position of the control points was refreshed in May 2019 when the weekly monitoring was initiated. The slope pin and piezometer data presented in this letter and subsequent monitoring data letters for the Ash landfill are meant to extend the information provided in the July 9, 2019 letter to NCDEQ. In this way the slope movements and water levels discussed herein draw from complete data sets for the pins and piezometers as collected since survey control at the landfill site was refreshed in May. Please note that the October 10, 2019 letter to NCDEQ mentioned some possible outlier data collected for the slope monitoring pins on September 12, 2019 and those outliers were confirmed by the September 24, 2019 pin monitoring data. The slope pin data collected for this letter (i.e., data collected on October 21, 2019) further confirm the September 12, 2019 data as outliers. ENVIRONMENTAL • CIVIL • GEOTECHNICAL • WATER • COMPLIANCE 19148 20191108da.docx SME Aak SEVEE & MAHER_ ENGINEERS SLOPE PINS There are nineteen slope pins installed in the surface of the Ash Landfill to monitor for possible slope movement. The pin identifications, in terms their horizontal coordinates and elevations, are listed in Table 1. The pin position information in Table 1 is based on survey completed on May 15, 2019 by Carolina Mountain Survey (CMS) of Brevard, North Carolina. Graphical data displays for the slope pins are presented in Attachment 1 to this letter. The displays show the following: • A plot of the horizontal movement of each pin since May 15, 2019; and • A plot of the vertical movement of each pin since May 15, 2019. It should be noted that the October 2019 pin measurements of horizontal movement are shown as green data points on the Attachment 1 plots in effort to distinguish the recent data from previous data. Discussions with CMS regarding precision and accuracy relative to the horizontal and vertical survey for the slope pins indicates that though the precision provided by the survey instruments used for the pin locations is quite high (to the nearest 0.001 foot or less) it is likely that the accuracy of the horizontal and vertical measurements from a practical standpoint is more or less on the order of % inch (i.e. approximately .05 feet [e.g., about the diameter of a dime]). As such it is important to understand, that for the purposes of this letter, pin movements (both horizontal and/or vertical), which are less than inch as compared to the initial location for the same pin are likely not indicators of landfill movement. Similarly, pin movements in excess of% inch are not considered to be an indication of landfill movement until at least two follow up consecutive readings support that deformation of the landfill has occurred. This consideration of corroborating measurements avoids potential false -positives due to such things as human error. Review of the horizontal movement plots show that the green data points generally fall within the grouping of previous data points, which indicates that little to no pin horizontal movement has occurred since May 2019, within the accuracy of the survey. Similarly, review of the vertical moment plots shows essentially no elevation change for any of the pins since May 2019, within the accuracy of the survey. PIEZOMETERS Eleven piezometers in the Ash Landfill are used to monitor for water level changes in the waste deposit. The piezometer identifications and associated elevations (i.e., the top of the piezometer pipe, piezometer tip, and local ground surface) are listed in Table 2. The piezometer elevation information shown in Table 2 is based on survey performed by CMS in May 2019. Table 2 includes a summary of the water level data collected during the period of May 7, 2019 through October 22, 2019 as well as water levels measured at the Ash Landfill since May 2014. Water level monitoring has been performed in various piezometers in the Ash Landfill since 2007. Review of the piezometer water levels in Table 2 shows no changes that are considered technically significant with respect to a possible changed condition in the waste deposit. Review of Table 2 also shows that the water levels in the piezometers are suggestive of a water table in the landfill that is at, 19148 20191108da.docx November 8, 2019 Page 2 of 3 SME Aak SEVEE & MAHER_ ENGINEERS or near, the lower limit of the waste deposit. Visual inspection of the Ash Landfill's piezometer water level history shows no changes or trends that are considered potentially problematic relative to the geotechnical performance of the waste deposit. CONCLUSIONS AND RECOMMENDATIONS The slope pin monitoring data presented and discussed in this letter indicate that little, if any, movement of the Ash Landfill has occurred since mid -May 2019 or possibly before. The piezometer monitoring data collected for the Ash Landfill shows no apparent changes in the waste deposit water levels that are considered sufficient to cause large vertical deformations or changes in slope stability. As of October 2019 the slope pin and piezometer monitoring frequency has been adjusted to once per month. The basis of the frequency change (first weekly, then bi-weekly, and now monthly) is the steady vertical and horizontal positions of the slope pins observed since the slope pin monitoring was initiated in May 2019. The next data evaluation letter to NCDEQ is planned for early December 2019, barring no unforeseen conditions relative to landfill behavior are identified.
