1.1.1 Incident Category
Time-critical removal action.

1.1.2 Site Description
The Bennett Landfill Fire Site is a former construction debris and nonhazardous industrial waste landfill (defined by state regulations as a Class II landfill)  that was additionally permitted to accept certain types of asbestos waste. 

The landfill ceased accepting waste in 2014. On November 2, 2014, the landfill was found to be on fire and was believed to have been extinguished by November 7th. Due to increasing smoke concentrations in January 2015, SCDHEC requested that the EPA conduct a Removal Site Evaluation (RSE). EPA signed an Action Memorandum on April 30, 2015 to conduct a Time-Critical Removal Evaluation and mobilized to the Site to begin removal activities on May 26.

Additional information for this section is available in POLREP #4 from 6/5/2015.

1.1.2.1 Location
The Site is located at 4399 Pinkney Road, Chester, Chester County, South Carolina. The geographic coordinates of the Site are 34.7874300 degrees north and 81.4502500 degrees west.

Additional information for this section is available in POLREP #4 from 6/5/2015.

1.1.2.2 Description of Threat
The fire at the Bennett Industrial Landfill is actively releasing chemical compounds into the air, including benzene and formaldehyde, which are measured near the fire at concentrations exceeding industrial RMLs for air and concentrations within the surrounding community that are greater than three times the residential RSL. Conditions at the Site, if not addressed, will continue to deteriorate over time and resulting in increasing quantities of exposed asbestos which are susceptible to transport by wind and other weather conditions to the nearby population. 

Additional information for this section is available in POLREP #4 from 6/5/2015. 

1.1.3 Preliminary Removal Assessment/Removal Site Inspection Results

2.1.1 Narrative

Vegetative cover installation was completed around the banks of the detention pond by October 23. Repairs to rill erosion on the asbestos cell was completed by October 26. Several coir logs were installed on the south edge of the landfill face to impede water flow along the steepest slope.

 Topsoil was installed at the top of the landfill near the edge of the bern at the top of the face; the topsoil covers an area of approximately 1/2-acre. It was seeded, fertilized, and covered with straw on October 26.

Installation of clay on the top of the landfill continued through October 26 leaving an area of approximately 1/4-acre prior to initiation of the rain delay. After work on October 31, the top of the landfill is nearly complete.

Rainfall beginning on the afternoon of October 26 an through October 27 delayed and ceased on-site work activities, which did not resume until October 30.

  2.2 Planning Section
    2.2.1 Anticipated Activities
The first priority of the removal action has been to address the burning debris pile by installing a soil cover. Isolation of the burning material and reduction of oxygen supply will significantly reduce emissions from the smoldering fire. The second priority of the removal action has been to address the eroding asbestos disposal cell by re-grading and covering the area.

Air sampling and monitoring activities have been completed.

The disturbed areas of the Site will be secured with vegetation to provide a stable erosion-resistant surface. Total project time has been updated to approximately 5 months.

2.2.1.1 Planned Response Activities
  • Isolation of burning material by removal and relocation of available fuel path and installation of earthen cover; (ONGOING)
  • Isolation of designated asbestos disposal cell through the installation of earthen cover; (COMPLETE)
  • Re-grading waste materials and native soils for purpose of cover installation; (COMPLETE)
  • Installation of temporary measures to prevent off-site migration of dust or contaminants as removal operations are conducted; and, (ONGOING)
  • Continue sampling and monitoring, as needed, for site safety purposes and to further delineate or identify contaminants. (COMPLETE)

2.2.1.2 Next Steps

  1. Complete initial and final clay cover on landfill top, then vegetate
  2. Repair channel dams with riprap
  3. Vegetate all remaining exposed areas
  4. Water until vegetation established

5.1 Regional Screening Levels (RSL) and Removal Management Levels (RML)
Regional Screening Levels (RSL) are conservative risk-based screening values developed by the U.S. EPA to help identify contaminants of potential concern. Contaminants that exceeded a RSL in at least one sample are then screened against industrial air Removal Management Levels (RML) that were calculated for this evaluation. RMLs are risk-based screening values developed by the U.S. EPA to determine whether sample concentrations are sufficiently elevated that they may warrant a removal action. Exceedance of a RML by itself does not require a removal action, nor does it imply that adverse health effects will occur.
