No methane gas was detected in the facility structures during this monitoring event. Permanent explosive gas monitoring devices are located in the scale -house and maintenance building. Methane gas was not detected in compliance monitoring points at concentrations above the lower explosive limit (LEL) during the second quarterly methane monitoring event. The next monitoring event is tentatively scheduled for September 2020. If you have any questions or concerns, please contact us at 336 852-4903. Sincerely, Golder As ciates NC, Inc.
