PROJECT REPORT
1.0 Introduction
The major concern with leachate is that it will migrate from landfills and contaminate either
surface or groundwaters. Therefore, collecting, transporting and removing leachate is of primary
importance to protect human health and the environment. A leachate collection/removal system
is one of two components required in Subtitle D landfills. The barrier layer being the other
component. State of Colorado Regulations Pertaining To Solid Waste Disposal Sites and
Facilities 6 CCR 1007-2, 3.2.5 (D) (1) states "A leachate collection system shall be designed and
constructed to maintain less than a twelve (12) inch depth of leachate over the barrier layer. and
to promote transport of leachate from the most distant point of the leachate collection system to
the leachate removal system in less than twelve (.12) months (assuming a saturated drainage
media)." Among the factors to be considered in the design of a leachate collection system
include the hydraulic conductivity of the drainage layer. The design and operations plan for
Eagle County Landfill requires that the leachate drainage layer shall consist of a sand and/or
gravel with an in -place hydraulic conductivity of 1 x 10-2 cm/sec or greater and a maximum
particle size of two inches.
On January 19, 2000 KRW Consulting. Inc. prepared and submitted a proposed design
modification for the drainage layer of module-3 and all future phases of landfill development.
This design modification proposes the optional substitution of tire shreds for the gravel drainage
layer. The shreds will have a nominal diameter of up to six inches and will be placed in a
minimum ten -inch thick layer. On March 24, 2000 Eagle County Landfill was approved by the
Solid Waste Unit of the Colorado Department of Public Health & Environment (CDPH&E).
2.0 Waste Disposal Module 4
In past Subtitle D landfill development. Eagle County Landfill has used aggregate -type material
as the drainage media, i.e., for waste disposal modules 1, 2 and 3. However. Eagle County chose
to utilize scrap tire shreds/ chips for waste disposal module 4 for the following reasons:
- locally obtained aggregate is expensive;
- the landfill had a large stockpile of scrap tires which could be shredded to produce a
useable product;
- shredding the stockpile would eliminate a potential fire hazard and the harboring of
disease vectors (insects and rodents);
- a design modification to utilize scrap tire chips/shreds for the leachate collection system
had been approved by CDPH&E; r
- promote scrap tire recycling and/or reuse;
- reduce costs by taking advantage of the Waste Tire Grant Program.
Page 1
Waste disposal module 4 was estimated to be approximately 5.5 acres in size. With a minimum
ten (10) inch thick layer of tire chips/shreds constituting the drainage layer, approximately 7.800
cubic yards of material would be required. An estimate of the scrap tire stockpile indicated that
processing the scrap tires would not generate enough shreds to complete the project. Therefore.
additional material would have to be purchased and imported.
Two separate bids were let: one for an outside contractor to come on site and shred the stockpiled
tires: the other to purchase tire shreds/chips from a vendor. Utah Tire Recyclers was awarded the
contract to shred the stockpiled tires at the rate of $110 per ton. Shredding operations
commenced May 29, 2002 and were completed June 25, 2002. Oxford Tire Recycling was
awarded the contract to supply and haul the balance of tire chips at the rate of $14.34 per ton.
Hauling operations began on April 11.2002 and were completed on August 15.2002.
Tile tire shredding project resulted in generating 1,276.17 tons of shreds at a cost of $140,378.70
and 3,349.34 tons of tire chips were purchased at a cost of $48,009.81. Total tonnage of both
projects was 4.625.51 tons; the equivalent of 462,551 scrap tires (1 ton = 100 tires). The total
cost for the drainage material was $188.388.51. Both vendors have been paid in frill.
3.0 Installation of scrap tire chip/shred material
All scrap tire chips/shreds were stockpiled adjacent to the module 4 construction area. Once the
clay barrier layer (liner) was installed, properly compacted and cut to design grades, the tire
material was hauled onto the liner by truck and dumped in truck -wide strips running north to
south. The material was then spread to a ten (10) inch thick minimum layer by a motor grader.
( Please see photographs.) After the engineering certification report is reviewed and approved by
CDPH&E, waste can be placed on top of the scrap tire material.
Due to severe water shortages, only approximately 3 acres of Module 4 were able to be
completed at this date. Water is a critical component of liner construction necessary for
achieving proper compaction densities and bonding between lifts. It is doubtful that the
remainder of Module 4 will be completed this calendar year since future availability of water is
bleak. It is planned and anticipated that the remainder of this disposal module will be completed
during Mav and June of 2003 when water supplies are replenished. The scrap tire chips/shreds
accumulated for this project will remain stockpiled in their current location for use at the later
date.
4.0 Conclusion
Scrap tire chips/shreds meet engineering specifications for use as leachate drainage layer
material. The chips are readily available at relatively low cost. Shredding costs are considerably
higlier: however, at least for this facility, shredding is a task done only after sufficient quantities
of'scrap tires are accumulated to make it worth while for someone to undertake the activity.
Handling and installing the tire chips/shreds is easy. fast and inflicts no apparent damage onto
Page 2
the clay liner. Lastly, this engineering application provides a great end use for waste tires. Eagle
County Landfill has approximately 29 acres of disposal space yet to be developed under the
current permitted Design & Operations Plan. It is conceivable that almost 19,500 tons of scrap
tire chips will be needed for the future construction of the leachate drainage laver. That
translates into almost 2 million scrap tires.

RE: Proposed Design Modification for Drainage Layer at Module 3
Eagle County Landfill
Dear Mr. Rasnic:

Colorado Department
of Public Health
and Environment
The Solid Waste Unit of the Hazardous Materials and Waste Management Division (the Division) has completed its
review of the above referenced document. The document was prepared by KRW Consulting, Inc.
Eagle County is proposing to utilize a minimum of a ten (10) inch thick layer of tire shreds in the drainage layer of the
leachate collection system. The proposed design modification is for Module 3 and as a construction option for all
future phases. As you are aware, this site is approved for six inches of sand and gravel in the leachate drainage layer.
The Division requires equivalency in all areas when substituting tire shreds for an approved landfill design component.
As a result of its review, the Division recommends approval of the proposed modification with the following two
conditions.
(1) Monthly leachate volumes will be collected. The volumes will be reported to the Division on a quarterly
basis. A minimum of six months of leachate volume data will be collected prior to placement of tire shreds.
(2) Leachate samples will be collected semiannually for one year. The samples will be analyzed for
Appendix I constituents. Additionally, a baseline leachate sample will be collected prior to placement of tire
shreds. The laboratory data will be reported to the Division with the required ground water monitoring
reports. ;
The Division is requiring these conditions because it is important to understand the functional relationship of tire
shreds and their ability to transmit fluids and to evaluate changes in leachate chemistry.
Based on the information provided and with the inclusion of the above referenced conditions, the Division
recommends that the proposed modification be approved and incorporated into the engineering design and operations
plan for this facility.
As always, should you have any questions regarding this matter, please contact me at (303) 692-3437.

Attention: Mr. Roger Doak
RE: Proposed Design Modification for Drainage Laver at Module 3 of the Eagle
County Sanitary Landfill, Eagle County, CO
Dear Mr. Doak,
On behalf of Eagle County, KRW is formally requesting approval of an optional design
for the drainage layer of Module 3, and as a construction option for all future phases, of
the Eagle County Sanitary Landfill in Eagle County, Colorado.
The approved liner design' includes a minimum 6-inch thick drainage layer with a
minimum hydraulic conductivity of 5 x 10-2 cm/sec. KRW proposes the optional
substitution of tire shreds for the gravel drainage layer in the construction of Module 3
and future landfill modules. The shreds will have a nominal diameter of up to six inches
and will be placed in a minimum ten -inch thick layer. A gradation of the proposed
material is attached as Annex A. Figure I illustrates pertinent changes on the design
details that were provided in the approved landfill design plan. ,
The irregular shape and slightly exposed wires included in the tire shreds will provide for
tighter packing and interlocking of the particles and, consequently, more protection of the
liner. It is less likely that refuse will penetrate the tire shreds than the gravel layer.
The compressibility of the tire shreds, estimated at 37% at the predicted loads, will result
in a layer of tire shreds of approximately 6 inches in thickness when fully loaded. The
hydraulic conductivity of the proposed material, approximately 1 cm/sec, is substantially
higher than the gravel previously utilized.
The American Society for Testing and Materials.(ASTM) issued a standard for the Use of
Scrap Tires in Civil Engineering Applications in 1998. This Standard, ASTM D 6270, is
included as Annex B. ASTM indicates that "the high hydraulic conductivity of tire
shreds, generally higher than 1 cm/sec, makes them suitable for mailv drainage
applications, including French drains, drainage layers in landfill and cover systems, and
leach fields for on -site sewage disposal systems."

A paper2 published by the Solid Waste Association of North America (SWANA) in 1996
concluded that
"Tire chips are technically viable for the following applications:
• Closure cap drainage layers;
• Leachate collection layer;
• Gas collection layers and trenches;
• Ground water control trenches; and
• Daily, intermediate and protective cover."
This paper is included in Annex C.
Although two problems have been noted in scrap tire utilization in engineering projects,
neither is antidipated in the proposed application. Leaching of organics from tire shreds
placed below the water table has been noted. However, testing referenced by ASTM
indicates that leaching of organics from tire shreds placed above the water table is not a
significant concern. Field studies referenced by ASTM further indicate that leaching of
manganese and iron may occur from tire shreds placed above the water table but at levels
which are not a significant concern. Fire hazards have been noted from the -use of tire
chips. Literature cited by ASTM indicates that exothermic reactions can occur in tire
shred fills of greater than 7 meters (22.5 feet) but are not a concern at the proposed
thickness.
Compressibility is a characteristic of tire shreds. Assuming a maximum refuse height at
Eagle County Landfill of 70 feet and a refuse density of 1200 lbs/yd3, we estimate the
maximum pressure to be 3,111lbs/ft2 (142 kPa). Using table X1.3 in Annex B a strain of
37% has been estimated. A strain of 40% has been used for design purposes. These data
are presented in Graph 1 in Annex D.

Tire shreds utilized at the Eagle County landfill will comply with the ASTM Standard (D
6270) for Class I fills (see Annex B, section 6.10.2-6.10.3).
Tire shreds have been used for landfill drainage layers in Subtitle D landfills since the
mid- 1990's in Iowa and Texas. Four Iowa landfills are currently using tire shred drainage
layers. Approximately 10 Texas landfills are using tire shreds for the drainage layer.
New landfills using tire shreds for drainage material are currently being permitted in both
states. -
Representatives of the Iowa State Health Department and the City of Iowa City, indicate
that the use of tire shreds for drainage layers in Subtitle D municipal landfills is an
acceptable alternative to the use of gravel. Engineers with the Department of Natural
Resources in Texas also consider the use of tire shreds an acceptable alternative. No
significant problems with construction, water quality, or fire hazard have been
encountered. References for knowledgeable engineers from the State of Iowa and the
City of Iowa City, as well as the State of Texas are provided in Annex E.
The use of tire shreds for a landfill drainage layer at Phantom Landfill in Fremont County
Colorado was approved by CDPHE on December 27, 1999.
