Potential Causes of Landfill Fires

Lithium Ion Batteries – not as common in Class III Landfills

Lightning – covered required every 14 days in Class III Landfills

Arson

Heavy Equipment Fires – park equipment away from

active disposal area

Hot Loads including:

Stumps from brush burning

Coals from fire places


3

Fire and SSO Prevention

Operator Training

Random Load Inspections

Segregate Suspicious Loads

Spread out and smother with soil

Keep stockpiled soil near the working face to cover

Keep a log of problematic loads and customers to check more

frequently

SSO’s are typically created by not properly extinguishing fires.


4

SSO Detection and Documentation

Smoke Observed by Operator

Usually accompanies a depression

Utilize an infrared temperature gun to delineate area

Notify the state regulatory agency immediately via email (written

documentation) and phone call, leave a voice mail.

Log the fire, who you called, immediate steps taken

SSO Action Plan Submittal – September 2017

SAFETY FIRST! – SSO can cause drop outs. Stay up wind of smoke.

Create a safety plan for your project.

Move active disposal area a minimum of 50 feet away from SSO.

Monitor and collect surface temperature data with an (IR) Infrared

Temperature Gun prior to implementing the action plan.

Cover entire area with copious amounts of soil (minimum 3 feet).

Monitor and collect surface temperature data with an IR temp gun

after implementing the action plan.

Dig test pits once a month to confirm the SSO is extinguished

through IR temp gun and Carbon Monoxide Monitoring.

SSO locations can be hard to pin point.

Digging test pits to confirm soil cover results.


10

SSO Plan Modification – November 2017

Digging test pits introduces oxygen to the SSO

Time consuming

Additional equipment and personnel required

Install monitoring probes


11

Added point 4

due to field

observation

while installing

points 1 thru 3.

Installing Probes 1 through 3 – November 2017.


12

January 2018


13

Nov. 2017 thru Jan. 2018 Probe Results

No longer

introducing

oxygen through

test pits and still not getting

favorable results.


14

JUST ADD WATER!


15

Added additional probes and a water source


16

WATER INTRODUCTION – FEBRUARY 2018


17

SLOPE DRAIN COLLECTOR

Temperature Results after Water Introduction

Fire was thought to have been

extinguished in March 2017.

Re-occurred in August 2017

Finally Extinguished with probes

and water February 2018.

Received TDEC Concurrence in

May 2018.
