Available at the facility entrance. (13)Accident Prevention. First aid at scale house and recycling area. A fire extinguisher is located in the scale house. (14) Spreading and Compaction of Solid Waste. Spreading waste in thin lifts and compacting with the Al-Jon compactor while the landfill was still receiving waste. The equipment appears to be achieving good compaction. (15) Cover Material. The City used both the Mercer tarp and soil material for daily cover while the site was still receiving waste. Generally 50-70 yards of cover material was used per operational day when using soil for cover. Soil cover was generally used only on Fridays unless weather conditions during other weekdays required it in place of the tarp. Phase 4 appears to be fully covered at this time with soil material. The City will continue to place street sweepings in Phase 4 for use as shaping and grading material until final capping construction begins in July.. (16) Vector, Dust, and Odor Control. Access roads were not dusty during the inspection due to rain earlier in the day. The flare was running during the inspection. The LFGTE facility was not operating during the inspection. The LFGTE is generally on line 24 hours per day except for down time required for maintenance or repairs. The LFGTE was not running due to maintenance during the time of inspection. (17) Litter Control. Windblown litter appeared to be picked up during the time of inspection. The lifter fence was removed after the filling in the active area ceased. (18)Top Slope and Side Slopes. Landfill slopes are in good condition. (19) Stormwater Drainage. Stormwater currently drains to the north side of the flare from the active area. (20) Erosion Control. No visible erosion during inspection. (21) Boundary and Elevation Markers. The City maintains a benchmark on the site. (22) Access Roads. Gravel access roads are generally in good condition. (23) Security. Access to the site is restricted by gates that are locked at the facility entrance when the facility is closed. The north construction entrance is locked unless needed for access. (24) Postinq of the Landfill. Signs at the entrance and within the facility are appropriate. There is good signage at the recycling drop-off area. Additional signs have been installed along the roadway to direct and keep traffic within designated areas. (25) Open Burning. None. (26) Fire Protection and Control.
