Dear John'
RE SKB Rosemount Industrial Waste Facility, SW -383
Liner Evaluation Following Cell 3A Surface Fire
As requested by SKB, Foth Van Dyke made a site visit on Thursday, July 13, 2006, to
observe and evaluate the liner in Cell 3A of the SKB Rosemount Industrial Waste Facility
following a surface fire Foth Van Dyke engineers Kathy Osborne and Curt Hartog
interviewed Mike Fullerton, Site Manager, and toured the waste and liner area in Industrial
Waste Cell 3A at 7'30 a m This letter and attached photo and location map provide the
results of our evaluation
Incident Background
The surface fire was discovered by an SKB employee on Tuesday morning, July 11, 2006, at
approximately 6 15 a m The employee immediately went to the main office area to get the
water truck and contact the Incident Coordinator (IC) Brad Pederson, the backup IC was at
the facility and he contacted Mike Fullerton, John Domke, Vice President of SKB and Rick
O'Gara, President of SKB Soon after, the County Sheriff and the Rosemount Fire
Department arnved at the site John Domke notified the city of Rosemount and Mike
Fullerton notified Dakota County and the Minnesota Pollution Control Agency
The fire occurred on the west side of the Cell 3A working face and progressed along the
surface of the disposal area around to the north side The area of impact was approximately
100 feet long and 60 feet wide, as shown on the attached map The working face is not up
against the cell side slope, though it is near the temporary phase delineation berm that is
covered with a sacrificial layer of 40 -mil low density polyethylene (LDPE) A second SKB
employee used a dozer to stop the eastern movement of the fire on the north side of the
working face by pushing soil up against the waste The water truck was used to spray the
waste and put out the fire The dozer then pushed the waste further out on to the sand
drainage layer so that the waste could be further and more thoroughly soaked with water The
Fire Department deemed the fire extinguished at 8 30 a m. and then left the site SKB
employees continued to water the waste until 10 00 a m as a further precaution

The working area for Cell 3A contains approximately 15 vertical feet of waste. It appears the
fire was contained to the upper approximately 1 foot of uncompacted waste The waste
appeared to be from approved industrial sources as per the facility permitted acceptable
material plan There was no evidence of tires in the waste The SKB Rosemount landfill does
not accept tires for disposal
The weather conditions for the morning of July 11 were reported to be cloudy with a light
wind east/southeast It started to ram at 10 30 a m that morning and approximately 0 75 -inch
of rain was recorded at the facility There was no sign of smoke on the working face on
Thursday morning during our evaluation
Evaluation
Based on our interview with Mike Fullerton and John Domke, and a review of the site
Contingency Action Plan, the SKB employees followed the plan appropriately The surface
fire was contained and extinguished with the appropriate measures The type of fire that
occurred on July 11 is not near the magnitude and much easier to handle than a subsurface
landfill fire Subsurface landfill fires take longer to extinguish and have indicators such as
smoldering, smoke, and waste subsidence None of these indicators were observed during our
site visit
The Cell 3A liner was constructed as a double composite geomembrane system There is a
geosynthetic clay liner (GCL), 60 -mil high density polyethylene (HDPE), a geonet for
secondary drainage, 80 -mil HDPE, a geocomposite for drainage and a 2 -foot sand protective
layer There was no evidence that the fire penetrated the sand protective layer Two feet of
sand is adequate to protect the liner below from temperatures encountered in this fire The
40 -mil LDPE used on the temporary phase delineation berm may have been subjected to high
temperatures since the wind could have blown the heat toward the phase delineation berm.
No heat damage or other stress was observed on the exposed 40 -mil LDPE Keep in mind
that the LLDPE over the phase delineation berm serves no environmental protection purpose
and will be removed in the future for the adjacent liner construction
Since Cell 3A has secondary containment and due to the amount of water that was used to
extinguish the fire, if there was a breach in the upper liner, water would be encountered in the
secondary sump. SKB has monitored the secondary sump in Cell 3A and no water was found
in the sump

Conclusion
It is our professional opinion that the liner in Cell 3A was not compromised from what we
would consider a small surface fire that occurred on Tuesday, July 11, 2006.
