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 (19) slope pins and eleven (11)
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 February 2020 and May
2020.

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 positions of the control points were
refreshed in May 2019, when the weekly monitoring was initiated.

SLOPE PINS

There are nineteen (19) slope pins installed in the surface of the Ash Landfill, which monitor for possible
slope movement. The pin identifications as of May 15, 2019, in terms their horizontal coordinates and
elevations, are listed in Table 1. The pin position information is based on survey completed 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]). Please note that in previous Ash Landfill monitoring letters sent to you, the graphical plots for the horizontal pin movements were shown as individual data points for all of 2019. Review of the 2019 data (May 15 to December 16) showed minimal horizontal pin movement occurred outside the range of the survey accuracy. To make the horizontal graphical plots more specific relative to data collected in 2020, the 2019 data for each slope pin was averaged and is shown as a single data point in the plots presented in Attachment 1. 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 includes a summary of the water level data collected during the period of May 7, 2019 through May 12, 2020 as well as water level elevations measured in the Ash Landfill piezometers 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 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. Consistent with the previous Ash Landfill evaluation letter sent to you (dated February 3, 2020), Glatfelter plans to continue to collect slope pin and piezometer monitoring data on a quarterly schedule. Glatfelter will evaluate the data after each monitoring event and maintain that data and evaluation on file for review by NCDEQ upon request.
