As part of the facility comprehensive inspection, groundwater monitoring wells were inspected. Several of the wells were found to be unsecured or to have broken locks. To achieve compliance, Davidson County must secure all groundwater monitoring wells, piezometers and probes with a locking cap. See table below for specific information about deficiencies. FACILITY COMPLIANCE INSPECTION REPORT Division of Waste Management Solid Waste Section Page 2 of 4 2. 15A NCAC 02C .0108(o) states: “Each non-water supply well shall have permanently affixed an identification plate. The identification plate shall be constructed of a durable, waterproof, rustproof metal or other material approved by the Department as equivalent and shall contain the following information: (1) well contractor name and certification number; (2) date well completed; (3) total depth of well; (4) a warning that the well is not for water supply and that the groundwater may contain hazardous materials; (5) depth(s) to the top(s) and bottom(s) of the screen(s); and (6) the well identification number or name assigned by the well owner.” Davidson County is in violation of 15A NCAC 02C .0108(o) for failure to ensure that all non-water supply wells have a permanently affixed identification plate constructed of a durable, waterproof, rustproof metal or other approved material that includes all of the information required by this rule. During this inspection, several of the monitoring wells were observed to be without the required permanent metal identification plate. To achieve compliance, Davidson County must affix a permanent metal identification plate, as specified in 15A NCAC 02C .0108(o), to the steel outer casing of all monitoring wells. See table below for specific information about deficiencies. SUMMARY OF OBSERVED VIOLATIONS: The following table lists all monitoring wells and any deficiencies observed during the inspection that require attention: Facility/Well Type/Well ID Lock in Place?

ADDITIONAL COMMENTS 1. The facility is a closed, unlined MSW landfill that ceased accepting waste in October 1993. 2. The primary focus of this inspection was the groundwater monitoring system. 3. All areas of the facility were easily accessible. Roadways are of all-weather construction and were observed to be well-maintained. 4. The facility has well-established vegetative cover, and no signs of erosion were observed. Slope drains appeared to be functioning. No ponding water was observed on the top or at the toe of the landfill. 5. Mowing had taken place at the facility the week prior to this inspection. Some woody vegetation was observed near the toe of the landfill and around some of the slope drains. Mr. Sink indicated that he would have the mowing contractor return and remove the woody vegetation from these areas. Please ensure that all woody vegetation is removed from the cap of the landfill. 6. The public horse trail system that had been developed on the closed landfill property has fallen into disuse, according to Mr. Sink. The automatic gate that had previously allowed access to the public had been replaced with a padlock and heavy chain. Mr. Sink explained that some vandalism and illegal dumping had taken place at the facility, and that increased security measures had been undertaken as a result. 7. Passive landfill gas vents located at the facility were observed. All were accessible and appeared to be functioning. 8. The groundwater monitoring system consists of 16 wells and 3 surface water points. All of the monitoring wells were observed. (See Observed Violations section of this report for additional information.) Several of the monitoring wells were difficult to access, due to heavy growth of underbrush and briars. Please ensure that the area immediately surrounding each monitoring well is clear of vegetation and that all wells are accessible for inspection and maintenance. 9. The semi-annual groundwater monitoring records for the sampling event that took place March 20-24, 2017 were reviewed. SW-3 was not sampled as a part of this event because it was dry. The report covering the March 2017 sampling event indicated no exceedances of the 2L standards. The report for the fall 2017 sampling event had not yet been received at the time of this inspection. 10. DS29-002, the temporary disaster debris storage site, is located adjacent to the closed landfill facility. The site is secured with a gate and is easily accessible. The site was last activated in 2014, and Mr. Sink stated that it had been adequate to handle temporary storage of the debris that had accumulated during that storm event. The item(s) listed above were observed by Section staff and require action on behalf of the facility in order to come into or maintain compliance with the Statutes, Rules, and/or other regulatory requirements applicable to this facility. Be advised that pursuant to N.C.G.S. 130A-22, an administrative penalty of up to $15,000 per day may be assessed for each violation of the Solid Waste Laws, Regulations, Conditions of a Permit, or Order under Article 9 of Chapter 130A of the N.C. General Statutes. Further, the facility and/or all responsible parties may also be subject to enforcement actions including penalties, injunction from operation of a solid waste management facility or a solid waste collection service and any such further relief as may be necessary to achieve compliance with the North Carolina Solid Waste Management Act and Rules.
