Field work at the Ascon Landfill Site during the week of February 17 is planned to include:

PRESIDENTS’ DAY HOLIDAY: In observance of the federal Presidents’ Day Holiday on Monday, February 17, there will be no field work activity at Ascon.

SITEWIDE: There will be continued inspection and maintenance of stormwater management measures to maintain compliance with Ascon stormwater permit. Stormwater management measures are subject to inspection by the City stormwater inspector. A routine City stormwater inspection at Ascon was conducted on February 6.

EASTERN ZONE: Improvements to the Pit F tent foundation are planned, including placement of stone and gravel near the base of the tent, as part of ongoing maintenance of the tent structure. Stone and gravel will be moved to the tent area to prepare for this activity.

Equipment used for this work may include:

  • Skid steer or front end loader to carry and deposit stone and gravel

SITEWIDE AND OFFSITE: Air quality monitoring continues, both on the Ascon site and at offsite community locations. Air quality monitoring data are posted under the Actively Monitoring Air Quality tab and also on the Ascon Landfill Site web page on the California Department of Toxic Substances Control (DTSC) website, Envirostor.

The offsite air monitoring trailer next to the Banning Branch Library and Eader Elementary School was returned to service on Tuesday, February 11, after the trailer was placed on Monday, February 10. The trailer was removed following vandalism and damage to the trailer and theft of air monitoring equipment on January 23. To improve visibility of the air monitoring trailer to deter vandalism, it is now located in the front parking lot of the library.

SITEWIDE: Weed abatement will be conducted as needed throughout the Site as part of stormwater management and fire protection. Plant overgrowth is removed near silt fences as part of necessary weed abatement, leaving roots in place to help prevent erosion.

Equipment used for this work may include:

  • Small power equipment, such as a weed wacker or mower
  • Front end loader to remove plant cuttings

SITEWIDE: Dust and odor mitigation measures continue to be implemented. This includes applying a non-toxic odor suppressant material in excavated and graded zones which forms a hard clay-based shell, covering excavated materials with reinforced plastic covers, and also use of a water truck to mist interior roadways and areas where field work is occurring. Learn more about these ongoing activities and other activities conducted to maintain a safe cleanup project under the Our Safety Commitment tab.

SITEWIDE: Supplies needed for ongoing Site maintenance are expected for delivery. Several truck deliveries of stone and gravel are anticipated for the maintenance work on the Pit F tent (near Magnolia Street).

SITEWIDE: 24-hour onsite security continues.
