Southeast Corner - EVOH Patch Repair -- On Saturday morning, Mar. 14, 2015, the Department received a call from Pattonville Fire District with a public report of a potential leachate outbreak/broken pipe and odors on the southeast corner of Bridgeton Landfill’s South Quarry. Bridgeton Landfill staff was notified by the Department of the potential problem. At the time, Department air monitoring staff were conducting daily air monitoring activities and deployed SUMMA canisters for laboratory analysis of any air emissions. Bridgeton Landfill staff informed Department staff, upon arrival at the site, that overnight Friday, Mar. 13, 2015, an issue with the landfill's flare allowed the EVOH capping material on the south slope to pillow up and which may have caused a 6 inch EVOH patch on the southeast corner to break free at a seam. Bridgeton Landfill staff increased vacuum to the south slope through use of the facility’s east side flare reducing the pillowing of the capping material and replaced the EVOH patch.

Subsurface Fire -- Northerly Extent in the Neck -- The latest data indicates the subsurface fire remains between the Gas Interceptor Well (GIW) System Lines or just to the north of the GIW System Lines.

  • Bridgeton Landfill has been reporting temperatures from fourteen (14) gas extraction wells (GEWs) in the Neck Area of the landfill on a weekly basis as required by the department's Oct. 7, 2014 letter.
  • Two temperature monitoring probes (TMPs -24 and -26) located along the “northern-most area” of the North Quarry are now being reported on a weekly basis. 
  • The installation of seven (7) other new temperature monitoring probes (TMPs) in the mid-point of the North Quarry has also been completed.The temperature data provided from these newly installed TMPs along with the existing TMPs allows landfill staff, the department and our contracted landfill experts to better analyze and track the movement of the subsurface fire.  Temperature data from the TMPs can be viewed in the Weekly Report section below.
  • Two additional TMPs were installed in the South Quarry to assist in analysis of the Heat Extraction Pilot Study. These TMPs began being reported by Republic Services during the week of February 27, 2015.
  • Bridgeton Landfill submitted a corrective action assessment/plan for the Neck Area leading into the North Quarry detailing methods for stabilizing and maintaining temperatures at or belowa specified level within the identified corrective action zone.The department is currently preparing a response to the plan.
  • Expanded carbon monoxide data collection is ongoing per the Second Amendment to the First Agreed Order.The department’s contracted landfill fire experts continue to monitor the carbon monoxide data as it is provided by Bridgeton Landfill.

South Quarry -- Continues to experience high activity from the subsurface fire especially in the area along the south slope of the South Quarry.

Construction activities around the South Quarry at Bridgeton Landfill are ongoing.When traveling along Boenker Road in the area of Bridgeton Landfill, construction equipment and activity may be observed as the landfill installs additional landfill infrastructure, i.e., piping, and electrical service to a lift station to address impacts from the subsurface fire.   Bridgeton Landfill has completed installation of a lift station in the southeast corner of the landfill property.This lift station is part of the landfill’s infrastructure used to move leachate and condensate to the pretreatment plant.

Upcoming or Recently Completed Construction – The Expanded Heat Extraction Pilot Study using cooling pipes in the GIW System is underway and the first quarterly update report was received by the department on Jan. 20, 2015.

March construction plans include:

  • Installation of an 18” line to improve vacuum to the southern-most portion of the South Quarry which is currently heavily impacted by the subsurface fire.
  • Work continues on the force main to transport pre-treated leachate from the Bridgeton Landfill pre-treatment plant to the Metropolitan Sewer District's (MSD's) Bissell Point treatment facility. The estimated completion date for the force main project is currently March, 2015.

Air Sampling and Monitoring by the Department – The department continues air monitoring and sampling around Bridgeton Landfill, as detailed below. Department of Health and Senior Services (DHSS) reviews the data and their review along with the data are postedon the department's website. Note:Results of comprehensive air sampling events and weekly Summa® canister samplings are made available upon receipt of the lab analyses.

Department air sampling and monitoring includes:

  • Daily monitoring by department staff using handheld units for detecting hydrogen sulfide and benzene as well as odor monitoring with an olfactometer, i.e., Nasal Ranger®, is completed on, at least, a twice daily basis.
  • Continuous air monitoring using the department's AreaRAE® system.
  • Weekly summa canister sampling for volatile organic compounds.

Comprehensive Air Sampling Events-- Ongoing at approximately 6-month intervals per the Second Amendment to the First Agreed Order. A comprehensive air sampling was completed during July 2014.Results from the lab are currently under review by the Department of Health and Senior Services.Reports from the comprehensive air sampling will be added to the department's webpage along with the Department of Health and Senior Services' Review when complete.

A comprehensive air sampling was completed on Jan. 26-29, 2015.As noted above, results of this sampling event will be made available on the department’s website upon their completion.

Odor Management Plan and Odor Evaluation Pilot Study —The Odor Management Plan was submitted as per the Second Amendment to the First Agreed Order.Bridgeton Landfill is currently evaluating other alternative odor mitigation technologies and will be providing a new plan to the department.The department received on Jan. 22, 2015 a Sulfur Removal Technology Evaluation Stage 2 submittal from Bridgeton Landfill.  The department provided a response on February 11, 2015 to the Bridgeton Landfill Sulfur Removal Technology Evaluation Stage 2 submittal. View response. (Link to copy of letter.)

Ground Water (GW) Detection Monitoring -- Historically, ground water data from the ground water monitoring well network has been collected on a semi-annual basis.

  • Ground water monitoring wells of concern are located very close to the waste mass (within approximately 50 feet).
  • Assessment monitoring is now required for both Appendix 1 and Appendix 2 parameters.
  • Monitoring frequency has been increased from semi-annually to quarterly.
  • Completion of a corrective action assessment along with a report is due within 90 days of the department’s letter.
  • The department received Bridgeton Landfill’s responses to comments on the Assessment Monitoring Plan, the Third Quarter 2014 Assessment Monitoring Event Summary Report and an Assessment of Corrective Measures during October 2014 which are currently under review.
  • The department received Bridgeton Landfill’s Quarterly Detection and Assessment Groundwater Monitoring Report on Dec. 19, 2014.

(Note:See the department's response letter dated July 30, 2014 in Archived Reports.)

Settlement Monitoring -- Significant settlement continues to occur in the South Quarry (a maximum of a 1.75 foot drop was reported in Jan. 2015). A settlement front map submitted by Bridgeton Landfill is included in the Monthly Report. (See New Reports Section below.) Note: Bridgeton Landfill has reported the physical characteristics of the landfill continue to change significantly since settlement mapping was begun at the landfill.In recent weeks, a significant number of new roadways and pads to allow for installation of infrastructure, i.e., gas extraction well replacements, temperature monitoring probes, leachate collection sump repairs and filling to allow for stormwater drainage, have added to the complexity of accurately mappingsettlement in the South Quarry.

Slope Stability Monitoring -- An assessment is required every quarter under the Second Amendment to the First Agreed Order. The Quarterly Slope Stability Report was due on Jan. 20, 2015 and the next report is due by Apr. 20, 2015.

Leachate Management -- Pretreatment and disposal is approx. 2.1 million gallons, per week, which is currently being trucked to and treated at MSD’s Bissell Point facility.

Landfill Gas Collection and Control System -- Routine maintenance of the gas collection and control system continues.

Reporting -- Weekly and Monthly Reports continue per the First Agreed Order and the Second Amendment (reporting temperature, carbon monoxide and other gas composition, settlement, leachate levels, trendanalyses, etc.)

Air Sampling and Monitoring Reports

Missouri Department of Natural Resources -- The department continues to conduct field operations from an observation trailer near the Bridgeton Sanitary Landfill.  The department is conducting air monitoring through an AreaRae multi-sensor system that collects data on volatile organic compounds, hydrogen sulfide, carbon monoxide and gamma radiation on a 24 hour per day/7 day per week basis.  The department is also conducting air monitoring activities, at 13 locations using a hand-held hydrogen-sulfide detector, a benzene detector and an odor detector. This monitoring occurs around the perimeter of Bridgeton Sanitary Landfill two times per day or as needed based upon community complaints received between the two daily cycles. Air monitoring reports will be posted twice weekly on Tuesdays and Fridays along with the Department of Health and Senior Services evaluation reviews.

Additional information about air sampling and monitoring can be found on the Archived Reports webpage.

Apr. 4, 2015 -- Daily Air Monitoring Results -- Air monitoring activities continue as the department collects data via our AreaRAE system on a 24 hour per day/7 day per week basis.  Daily monitoring events by the department continue to be completed twice per day on a scheduled path.

AreaRae Operations - In times of extreme weather and atmospheric conditions, sensitive electronic equipment, including AreaRae air monitors, may be set to standby mode to avoid damage to the units. When this occurs, the use of handheld air monitoring devices will continue, with additional use and deployments added as is necessary and possible, in addition to the regular, twice-daily scheduled paths. Supplemental use of the handheld air monitors will continue until atmospheric and weather conditions allow for the AreaRae monitors to be brought back into operation.
