  • Waste Management Daily Progress Report

    Waste Management Daily Progress Report shows workers continue to investigate the liner in Cell E6, and expect an assessment to be complete by Saturday, Feb. 5.

  • Waste Management Daily Progress Report

    Waste Management Daily Progress Report shows the same assessment of Cell E6, where workers are removing rocks to better investigate the liner. Work on the stormwater diversion channel continues without notably changes. The contractor removed 16,000 gallons of mud and water and placed the muck in tanks so it separates. Workers pumped 56,000 gallons of stormwater from the sedimentation basin to be treated for disposal.

  • Waste Management Daily Progress Report

    There is still no change to the assessment of the liner in Cell E6, according to Waste Management's daily progress report report. The landfill operator reports progress on construction of a stormwater diversion channel, and continued pumping efforts to get muck and stormwater out of the area around Cell E6.
  • EPA Deadline: Structural Report

    Waste Management meets deadline to provide analysis of the structural integrity of the landfill cell from which garbage spilled. As required, the analysis was conducted by a "qualified civil or geotechnical engineer."
  • Waste Management Daily Progress Report

    Waste Management finished laying pipe for the diversion channel, according to the company's daily progress report report. Cement will be poured on Tuesday. Crews have begun their investigation of a exposed side wall liner in Cell E6.
  • Waste Management Daily Progress Report

    The Feb. 7 progress report shows some delays to repair in Cell E6 from weekend rain. The City's director of Environmental Services, Tim Steinberger, told Civil Beat the rain caused delays but wasn't heavy enough to cause more damages or flooding. Despite delays, Waste Management reports it is meeting deadlines to comply with the EPA order. Workers are still pumping thousands of gallons of mud from Cell E6.
  • EPA Deadline: Liner Repair

    Within two weeks, Waste Management must outline a plan to fix the damaged liner that keeps trash from seeping into the ground.
  • Waste Management Daily Progress Report

    The Feb. 8 progress report says protective stone was removed from the damaged landfill cell to allow further investigation of the liner material. Some damage was repaired, but limited access slowed progress. The final concrete pour for the wall of the diversion channel was also delayed when the truck had difficulty access the area due to mud. The pour was set to take place Feb. 9 instead.
  • Waste Management Daily Progress Report

    Waste Management's daily progress report shows some delays due to muddy conditions in Cell E6, but progress on the stormwater diversion channel. Workers pumped more than 52,000 gallons of stormwater out of the sedimentation basin for treatment and disposal.
  • EPA Deadline: Diversion Channel

    With three weeks, Waste Management must complete construction of a functional stormwater diversion channel. (City officials had said the completion of that channel before the heavy rains could have prevented the landfill spill.) The landfill operator must also stop liquid discharges from that cell — except those permitted — from flowing into the ocean by that time.
  • EPA Deadline: Final Report

    Within 60 days, Waste Management must submit a final report summarizing the company's compliance with the order as a whole.
