Pads fo r the facilities were well maintained and <br />stable. There were no major concerns with erosion. The access road to the north side of the Nitrogen #2 Plant was <br />repaired since the last inspection. The culvert at the same location was noted to be plugged during the March 2019 <br />inspection. The culvert was located and unplugged during this inspection (Photo 16). Rills coming off the fill <br />slope of the 13L Return Shaft pad were identified. The rills were not significant enough to create concerns of <br />instability at the site.
