Subject: Evaluation Report of Slope Pin and Piezometer Monitoring Data
Ash Landfill
Glatfelter
Pisgah Forest, NC
Dear Ms. Aja
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
a possible landfill movement as identified from previous monitoring of several of those same
instruments. This letter addresses monitoring data collected for December 2019. This letter also
discusses Glatfelter’s plans for monitoring the Ash Landfill in 2020, and beyond.
The slope pin monitoring consists of measuring 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.
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.

Discussions with CMS regarding precision and accuracy relative to the horizontal and vertical survey for the slope pins indicates 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 the accuracy of the horizontal and vertical measurements, from a practical standpoint, is more or less on the order of ½ inch (i.e. approximately .05 feet [e.g., about the diameter of a dime]). Review of the horizontal movement plots for slope pins Ash 1 through Ash 6 and Ash 31 through Ash 36 shows the December 2019 slope pin data generally fall within the grouping of previous data points, and thus indicates little, if any, horizontal pin movement has occurred since May 2019 (i.e., within the accuracy of the survey). The December 2019 data for slope pins Ash 21 through Ash 27 however shows several cases where horizontal moment exceeded ½ inch (i.e., 0.54 inches to 0.69 inches). In the CMS data deliverable for December 2019, CMS indicated weather conditions were breezy for the December survey and the breeze likely affected the longer survey shots, which are mostly associated with slope pins Ash 21 through Ash 27. To this end, the December 2019 data for slope pins Ash 21 through Ash 27 are not considered to be suggestive of significant slope movement but rather are considered as potential outliers for purposes of this letter. Review of the vertical movement plots for the slopes pin shows essentially no elevation change has occurred (within the accuracy of the survey) for any of the slope pins since May 2019, when the more frequent monitoring schedule was implemented. PIEZOMETERS Eleven piezometers are used to monitor for water level changes in the Ash Landfill’s 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 a vertical survey performed by CMS in May 2019. Table 2 also includes a summary of the water level data collected during the period of May 7, 2019 through December 20, 2019 as well as piezometric elevations measured at the Ash Landfill since May 2014. 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 the water levels in the piezometers are suggestive of a water table in the landfill that is at, 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 The slope pin monitoring data presented and discussed in this letter indicates 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 only small water level changes in the waste deposit, which are considered insufficient to cause large vertical deformations and / or changes in slope stability. Weekly, bi-weekly, and monthly slope pin and piezometer monitoring was completed at the Ash Landfill during the period of May 2019 through December 2019. Prior to May 2019 the slope pins and piezometers were monitored quarterly. The recent, more frequent, monitoring was performed to

address a possible landfill movement identified in May 2019. Evaluation of the monitoring data collected since May 2019 shows there is no reason to believe the Ash Landfill is undergoing any significant horizontal or vertical movement. The evaluation also showed the possible landfill movement identified in May 2019 was possibly caused by a faulty elevation benchmark used for survey of the slope pins. RECOMMENDATIONS There is no apparent reason to continue with the frequent monitoring schedule of the Ash Landfill slope pins and piezometers. Rather, it is recommended Glatfelter revert to quarterly data collection for the slope pins and piezometers using the same general quarterly schedule as that used prior to May 2019 (i.e., monitoring in mid-March, mid-June, mid-September, and mid-December). The next monitoring report for the Ash Landfill slope pins and piezometers will be submitted to NCDEQ following completion of the second round of monitoring (i.e. mid-June) of 2020. After that data submittal, it is recommended that Glatfelter return to maintaining the monitoring data on file for review by request.
