PROJECT INFORMATION AND STAFF COMMENTS
REQUEST: Certificate of Designation for the South Canyon
Landfill Amendment
APPLICANT: City of Glenwood Springs/CacaLoco Compost, Inc.
ENGINEERS: KRW Consulting, Inc.
LOCATION: A site located in portions of Sections 2, 3 and 10,
T6S, R9OW; generally located approximately 1.0 mile
south of the I-70 South Canyon Interchange, off of
County Road 134.
I. RELATIONSHIP TO THE COMPREHENSIVE PLAN
The area in question is identified as being within District E, Rural Areas Moderate to Severe
Environmental Constraints of the Garfield County Management Districts Map, that is a part
of the 1984, Garfield County Comprehensive Plan.
II. DESCRIPTION OF THE PROPOSAL
It is proposed to amend the Certificate of Designation for the operation of the South Canyon
landfill site on approximately 6-8 acres of land included in an approximately 500 acre tract
of land owned by the City of Glenwood Springs. CacaLoco Disposal, Inc. is the proposing
to amend the City's CD, to allow for a compost area. The original application was
submitted to the County in October of 1994 to demonstrate compliance with the federal
Subtitle D Regulations. In December of 1997, the County conditionally approved the
Certificate of Designation for the South Canyon Landfill. One of the proposal discussed,
but not approved as a part of the CD, was the proposed composting facility. At that time,
the CDPHE had not approved the proposed composting facility operating plan. Since
December of 1997, the State and the applicant have corresponded back and forth to resolve
issues. Resulting in the approval of the "Use and Distribution of Biosolids (See letters pgs.
3-17)
/3Z. - P/�o�ofv`�-
dfiPi e,4 A/ -1-
&-Se
1-
The application submitted indicates that the activities are occurring in an area directl uphill
of the landfill's sludge and septage ponds. (See application & maps pgs. /�`"" Z ) The
facility is designed to grind construction wood and other sorted organics to be co -composted
with sludge and septage. The intended service area is the same as the landfill, which is a 10-
15 mile radius around Glenwood Springs. The active compost area will consist of
approximately 0.5 ac. of recompacted native material to create a lined pond with a capacity
for over 100,000 gallons of incoming sludge and septage. The composted material will be
put in two different piles, depending upon the cycle of the process. The last stockpile may
be as large as 20-30,000 cu. yds. of material for sale to the public.
III. MAJOR ISSUES AND CONCERNS
A. State Statutes: C.R.S. 30-20-100.5 thru 30-20-119, defines the parameters by which
the Colorado Department of Health, Hazardous Materials and Waste Management
Division and the "governing body having jurisdiction" approve or deny an
application for a certificate of designation for a solid waste disposal site. The
applicant is required to obtain a recommendation of approval or disapproval from
the Colorado Department of Public Health and Environment. In considering an
application for a proposed solid waste disposal site and facility, the governing body
having jurisdiction shall take into account:
(a) The effect that the solid wastes disposal site and facility will have on the
surrounding property, taking into consideration the types of processing to be used,
surrounding property uses and values , and wind and climatic conditions;
(b) The convenience and accessibility of the solid wastes disposal site and facility to
potential users;
(c) The ability of the applicant to comply with the health standards and operating
procedures provided for in this part 1 and such rules and regulations as may be
prescribed by the department;
(d) Recommendations by the local health departments.
B. Zoning : The applicants state that the landfill has been located on the same property
since 1951 and as such is a nonconforming use.
VI. RECOMMENDATION
That the Board of County Commissioners approve the Amended Certificate of Designation
for the South Canyon solid waste disposal site with the same stipulations tied to the CD
issued in December of 1991

Construction Report
Certificate of Designation Addendum
CacaLoco Compost at South Canyon Landfill
Garfield County
Dear Mr. Duke:
Colorado Department
of Public Health
and Environment
The Hazardous Materials and Waste Management Division (the Division)
of the Colorado Department of Public Health and Environment
completed its technical review of the construction report submitted
as additional information for the addendum to the Certificate of
Designation to include the CacaLoco Compost Facility. The proposed
compost facility is located in the southern portion of the South
Canyon Landfill property located in portions of Sections 2,3, 10 and
11, Township 6 South, Range 90 West of the 6th P.M. in Garfield
County. The compost site is approximately 8 acres in size with a 1,4
acre pad utilized for active composting and the remaining area for
equipment, raw material and final product storage.
The..00nstruction report review includes a determination of its
compliance with requirements set forth in the Solid Waste and
Disposal Sites and Facilities Act, Title 30, Article 20, Part 1 of
the, Colorado Revised Statutes, as amended and with the regulations
promulgated thereunder 6 CCR 1007-2 (the Regulations).
The construction report provided the additional engineering
information requested in my April 14, 1997 letter, however, several
areas of the compost addendum continue to need clarification or
modifications to meet the requirements of the regulations. The
Division's comments are as follows.
December 16, 1997
Mr. Duke
Page 2
1. The second paragraph in the "Drainage" section of the original
addendum indicates that one of the existing septage
impoundments will be emptied over the next year, the bottom
would be re -compacted and utilized for site run-off
containment. Please include specifications for the proposed
re -compacted pond liner. Operations must be limited to the
"new Hypalon lined pond" until the run-off containment pond is
available for use.
2. The first paragraph on page 4 recommends one foot of freeboard
for the holding pond. Subsection 9.5.4 of the Regulations
requires two feet of freeboard in impoundments. Please revise
the report and recalculate the usable pond capacity.
3. At what frequency will samples be collected from the compost?
4. A "Notice of Authorization" is required as outlined in the
state's Biosolids Regulations 4.9.0 (5 CCR 1002-19) by the
Water Quality Control Division for compost which uses a
biosolid feedstock. Contact Mr. Phil Hegeman at (303) 692-
3598.
5. What is the proposed moisture range of the compost?
6. Please describe the materials expected to be used in the
compost operation.
7. Provide approximate windrow height , width and length.
8. Provide a discussion on prevention of nuisance conditions,
especially odor control.
9. Please specify the maximum amount of feedstock stored at any
one time in the bulk material area, the active compost area and
the storage area.
10. Provide information on the projected end use of the compost.
11. Provide a section on record keeping that includes a daily log
of waste received, processed and in storage, temperature
readings and daily operations.
12. Will the composting hours of operation be concurrent with those
of the landfill? If not, how will access to both facilities be
controlled?
December 16, 1997
Mr. Duke
Page 3
13. Please provide a flow diagram of the operational process.
14. Please provide a contingency plan for the disposal of excess
raw materials or compost should market conditions prevent sale
of the product.
15. Please expand the closure portion of the plan to include time
frames necessary for the actual closure as well as appropriate
notifications as outlined in sections 2.5 and 3.5 of the
Regulations.
16. Financial assurance, per section 1.8 of the Regulations will be
required 90 days prior to beginning operations.
Please contact Donna Stoner at (970) 248-7168 if you have any
questions regarding this matter.

Dear Ms. Stoner,
In response to your most recent set of comments from December 16,
1997, CacaLoco's replies are as follows:
Replies are numbered corresponding to the Division's comments.
1. The pond in question is intended for the retention of
uncontaminated runoff and for the containment of any accidental
or catastrophic events. Only the runoff from the compacted pad
will be contaminated by septage and will be contained in the
hypolon lined pond. Pathogen destruction is achieved on the pad
prior to transfer to storage area.
It is assumed this pond will remain primarily dry (a historic
'stock pond' which attempted to catch the runoff from this valley
with asn earthen dam was well vegetated with dryland species and
showed no sign of ever having contained water) and it is unlikely
to ever contain contaminated materials. For these reasons, it is
proposed to recompact native material in 4-6 compacted layers to
a total depth of two feet in the same fashion used to construct
the mixing pad rather than to install a synthetic liner. The
pond is currently designed for a capacity of 1.5 million gallons
including a two foot freeboard. The estimated capacity after
installation of the two foot recompacted liner will be just over
one million gallons.
2. The hypolon lined pond was constructed with an overly
exaggerated low spot to provide a spillway directing any
accidental overflow to confinement in the existing sewage pond
below. It was possible to dig up and fold back the hypolon in
this portion, raise the embankment one foot with additional clean
backfill (sand), and reanchor the hypolon while still maintaining
a low spot to confine potential accidental overflows. This
allowed us to achieve the necessary two feet of freeboard without
changing the holding capacity of the pond.
3. Initially samples will be collected from each batch to
assure homgenisity of the product. Once this is established,
samples will be collected quarterly.
4. Lori Tucker has been contacted and our "Letter of Intent"
has been submitted to receive our "Notice of Authorization". No
compost will be removed from the site until so authorized.
5. The proposed moisture range of the compost will be 40-60%
during the active stages and below 40% for finished compost.
WNW
6. Biosolids consist of septage and sludges from septic
systems, portapotties and local waste water treatment facilities.
Bulking agents consist primarily of construction and tree
trimming waste wood ground up through a 4 inch minus screen.
Other materials inlude yard waste such as grass and leaves,
spoiled hay and straw, and animal manures and bedding.
7. A windrow is stacked as high as is possible utilizing a
Caterpillar 930 loader ( approximately 12 ft.) with a base of
about 20 ft.. Subsequent windrows are stacked against one face
of the original windrow creating a cell of cooking compost. The
largest cells constructed will be about 100 ft. long by 50 ft.
wide and 12 ft. high.
8. A wood chip pad with burmed edges is constructed on a
recompacted clay mixing area with drainage through a similar
secondary wood chip pad and then on into a hypalon lined pond.
These wood chip pads are basically elevated lagoons designed to
filter out solids and soak up as much liquid as possible. The
hypalon lined pond is equipped with a ten horse power, solids
handling pump used both to recirculate the pond for aeration and
to pump liquids back up to the upper mixing pad as necessary.
Biosolids are dumped into the upper pad where the wood chips
generally engulf and coat the solids during the dumping process
while liquids soak into the layers of wood chips below. Thin
layers of fresh wood chips are covered over biosolids daily or as
necessary to keep solids covered. When the upper pad becomes
full and nearly saturated (every three to five days) it is mixed
to incorporate the dry spots. It is then pushed downhill, and
formed into the secondary pad while a new upper pad of dry wood
chips is constructed to receive incoming biosolids. The previous
secondary pad has, prior to this process, been remixed and
stacked in 20 ft. by 20 ft. cells 12 ft. high allowing excess
liquids to drain back into the hypalon lined pond. These cells
heat rapidly achieving the desired temperature of 55 degrees
Celsius within several days and stabilizing the material rapidly.
These cells are then moved off the recompacted clay mixing area
and placed on the face of the larger windrow cells and covered
with a minimum of one foot of finished compost. Here they
rapidly reheat to the required 55 degrees celsius and maintain
these temperatures for 4-6 weeks. Upon cooling, these windrow
cells are restacked in large storage piles where they generally
reheat to a lesser degree. These storage piles seasoned for the
required 90 days and aerated as necessary for drying prior to
screening. The screened wood chips are recycled back to received
incoming sludge while the finished compost is either sold or, if
it reheats after screening, is turned and restacked until it
fails to reheat.
The large size of the wood chips (4 inch minus) used in this
process helps enhance volunteer aeration and prevents the
development of anaerobic conditions even without the use of
forced aeration. Any mixtures that fail to achieve required
temperatures (which hasn't happened yet) is, depending on
moisture content, either recycled back into the beginning of the
process or run through a stationary manure spreader for more
thorough aeration and then restacked.
The operator has employed the same basic process and materials
for several years at the Pitkin County Compost Facility and for
several months at the current site in South Canyon without
experiencing any problems in achieving temperatures, nuisance
conditions, vector control, or odor control.
9. The maximum amount of feedstock in the bulk material area
will not exceed 1000 cu. yds. with the majority of this material
consisting of unground construction waste wood. Volumes in the
active compost area will not exceed 500 cu. yd. and volumes in
storage will not exceed 5,000 cu. yd. (revised from first
submission).
10. Established markets in this region include several local
nursuries, several score of professional landscapers, the CDOT
for roadsisde revegetation, and the ski companies for
revegetation and slope stabilization. There are also several
mining operations slated for closure and revegetation in this
region
Although we intend to produce a Class A compost we will market it
for non -crop production uses concentrating marketing efforts on
the CDOT roadside revegtation and mining reclamation.
11. The daily logs of waste received are kept South Canyon
Landfill and are likely included in their Application for a
Certificate of Designation. Tim Danner of South Canyon Landfill
provides us with a monthly log of incoming material (see
attached).
12. The composting hours of operation are concurrant with those
of the landfill.
13. See attached flow diagram.
14. Any excess materials will be stockpiled for use in closure
and revegetation of portions of the landfill. In the unlikely
event of an extreme excess, these materials will be utilized for
daily cover in the landfill.
15. The Department and any local governing bodies having
jurisdiction will be notified in writing and the geneeral public
will be notified by the appropriate signs at the entrance of the
facility at least sixty (60) days prior to the closing date.
Closure activities will comehce within thirty (30) days of final
regrading. Site will be mulched with compost, stabilized from
erosion and reseeded within 180 days following the begginnnig of
closure.
16. Third party estimates have beer# forwarded to Glenn Mallory
and included herein for you (see attached). A request for an
extension until April 9, 1998 has also been sent to Glenn
Mallory. Meanwhile, a trust fund is being established based on
this amount and documentation is forthcoming.
Thanks again for your time in reviewing this application.
Sincerely, Jim Duke

Re: Additional Requested Information January 9, 1998
Certificate of Designation Addendum
CacaLoco Compost at South Canyon Landfill
Garfield County
Dear Mr. Duke:
The Hazardous Materials and Waste Management Division (the Division)
of the Colorado Department of Public Health and Environment
completed its technical review of the additional information for the
addendum to the Certificate of Designation for the CacaLoco Compost
Facility. This information was supplied January 9, 1998. The
proposed compost facility is located in the southern portion of the
South Canyon Landfill property located in portions of Sections 2,3,
10 and 11, Township 6 South, Range 90 West of the 6th P.M. in
Garfield County. The compost site is approximately 8 acres in size
with a IA acre pad utilized for active composting and the remaining
area for equipment, raw material and final product storage.
The review of the additional information includes a determination of
its• compliance with requirements set forth in the Solid Waste and
Disposal Sites and Facilities Act, Title 30, Article 20, Part 1 of
the, Colorado Revised Statutes, as amended and with the regulations
promulgated thereunder 6 CCR 1007-2 (the Regulations).
The report provided most of the additional information requested in
my December 16, 1997 letter, however, the following items need
clarification or modifications to meet the requirements of the
regulations.
1. Will sampling be conducted on the compost before transfer to
the storage pile or on the end product just prior to sale?
January 23, 1998
Mr. Duke
Page 2
2. Will a process log that confirms the amount of materials and
final product are consistent with your proposal be available
for review?
3. The response to comment #14 of my December 16, 1997 letter
included a contingency for only the end product (the compost).
Please expand the contingency to include use or disposal
alternatives for the raw materials, wood and septage, in the
event of unusable or excess amounts of either.
4. Your request for extension of the financial assurance
requirements, per section 1.8 of the regulations, until April
9, 1998 is granted.
5. The Division requires that a detailed closure plan be submitted
for approval at the time of notification. Garfield County -may
require additional lead time of your closure activities in
order to establish an alternative for septage disposal.
I am now preparing to request public comments. Please provide the
information requested above to the Division and Garfield County so
that we may proceed.
Please contact me at 970-858-0341 if you have any questions
regarding this letter.

Dear Ms. Stoner,

FSR o 9 1998
GA iFttLC UNT`f
4- 9,1?
This letter is in response to the Divisions comments in your
letter of January 23, 1998.
1) Although the PFRP process is completed on the recompacted pad
and the material is thoroughly drained of free liquids while still
on this pad, the samples for analyses have been pulled from the
storage pile after transfer from this area. This process was
chosen primarily to maximize the stability and volatile solids
reduction of the material prior to sampling, but could be changed
to sampling prior to removal from pad if deemed necessary.
2) Yes. Records are kept of the volumes of incoming wood wastes
and biosolids. The volumes of wood chips produced from these
incoming waste woods and wood chips imported from other sources
are also recorded as well as the volumes of wood chips recycled
back into the process from the screening process. The volumes of
biosolids mixed with any given volume of wood chips, however, is
difficult to estimate because the chips retain varying amounts of
the biosolids depending on their solids content. The leachate
from these mixtures which is captured in the hypolon lined pond is
recirculated back to the mixing area through a solids handling
pump that is not conducive to flow measurements.
3) Any unchipped wood wastes will be disposed of in the
construction waste portion of the landfill. Chipped wood will be
utilized as daily cover at the active landfill pit. Because wood
chips and stabilized compost are far easier to dispose of than
septage, we will attempt to always maintain a supply of wood chips
sufficient to mix, heat, and stabilize our maximum holding
capacity of septage such that it can be used for revegetation,
daily cover, or as a last resort, be landfilled. In the event
that we end up with an excess of septage after all wood chips have
been utilized, the septage will be recirculated over the
recompacted pad until it is sufficiently dewatered and thickened
through evaporation to be retained on the pad and spread thin for
further drying. When sufficiently dry, the material will be
applied as a Class B biosolids product if possible or landfilled
if necessary.
4) Thank you for the extension.
5) , Garfield County will be copied on these responses, forwarded
a copy of my last set of replies, and accommodated on any
additional requirements they might have.
Thanks again„fr time in reviewing these responses.

CacaLoco Compost Permit Addendum for the South Canyon Landfill,
Garfield County, Colorado.
I. GENERAL DATA
Tues Jan 21 97 13:35 PAGE 2/4
a. Title and Names:
CacaLoco Compost Inc. (For Tadco Inc., South Canyon Landfill)
8256 Flying Fish Rd.
Carbondale, CO 81623
(970) 963-8381
Contact: Jim Duke (see attached resume', exhibit A)
Date Prepared: January 2, 1997
b. Location:
(see South Canyon permit for vicinity and legal desc.)
The compost area within the landfill permit will consist of the
narrow valley extending southwest of the existing sludge and
septage ponds. (see site map exhibit 8)
c. Size:
This area includes an estimated 6-8 acres.
d. Disposal area
There will be no disposal on this site.
e. Type of Facility/discussion of service area:
This will be a compost facility designed to grind construction wood
wastes and other sorted organics to be co -composted with sludge and
septage.
The service area will be basically the same as for the rest of the
landfill including about a ten to fifteen mile radius around
Glenwood Springs. This facility will be dealing with existing
haulers and shouldn't impact existing traffic patterns.
II. SITE AND OPERATION PLANS
a. Site
The active site will consist of the relatively level (accessible)
floor of the valley directly uphill to the southwest of the
existing sludge and septage ponds. (see site nap, figures $1+ #2)
b. Drainage
There is an existing road along the lower contour of the northwest
slope of this valley which will serve, with minor regrading, to
divert any runoff from the higher drainages on this side. A
diversion ditch will be pulled along south east edge of the valley
floor to a point overlapping the diversion provided by the road on
the other side to provide complete diversion of potential runoff
from further up the drainage. (site map, fig. 43)
Ditches will be pulled to divert all on site run-off into the
existing septage pond. (site map, fig. # 6) When this pond is
emptied over the next year, it will be recompacted for this
purpose.
c. Mixing area
Tues Jan 21 97 13:35 PAGE 3/4
The active compost area will consist of approximately 8.5 acres of
recompacted native material. (site map, fig. 115) Preliminary
engineering reports indicate an inability to achieve the required
permeability coefficient through recompaction but by only a very
small margin.
It is proposed to recompact this working area to the highest degree
possible with four layers of recompacted material utilizing a
vibrating sheepfoot compactor achieving very nearly the required
impermeability. The mixing area will be compacted maintaining a
minimum of a 6:! slope to promote runoff instead of infiltration and
will be contoured to capture runoff in a completely impermeable
pond lined with 38 mil. hypalon. (site map, fig.114)
This pond will have a capacity in excess of 100,800 gallons
enabling the storage of over a month's worth of incoming sludge and
septage. Septage and sludge trucks will dump directly into the
pond. A solids handling trash pump will be used to spray the
septage over a several foot deep layer of wood chips spread out on
the recompacted and sloped mixing area. A large droplet size will
be used to minimize the formation of aerosols and particulates.
Excess sludge will flow directly back into the Iined pond.
d. Pathogen destruction
When nearly saturated, the wood chips will be stacked in solid
cells 6-8 feet in height on uphill half of the recompacted and
sloped mixing area which also drains back into the lined pond.
These cells will be covered with one foot of wood chips or finished
compost in order to achieve the required temperatures thoroughly.
The particle size of the wood chips being used will provide
sufficient aeration to achieve required temperatures and to prevent
anaerobic conditions without forced aeration or mechanized turning.
Cells of this design generally achieve a temperature in excess of
60 degrees centigrade within 2-3 days and hold this temperature for
several weeks. An aeration system and a mixing/aeration wagon will
be available, however, to be used if necessary.
During the aeration process, cells will be monitored for
temperatures per requirements of EPA 40 CFR 583 regulations.
Temperatures will be sampled at random locations throughout the
cells every three days for a three week period and the results
recorded. Any cells or portions of cells failing to achieve
desired temperatures for pathogen destruction will be excavated and
remixed and aerated through a mixing wagon.
Periodic samples of the compost will be pulled from random
locations within each cell, blended to form a composite sample and
tested for all pollutants and pathogen levels as defined in EPA 40
CFR 530 regulations.
Incoming materials to be used for composting will be carefully
screened both to maintain quality control and to inspect for
hazardous materials.
e. Stabilization and Stockpiles
Upon completion of the initial aeration and stabilization process,
compost will be hauled to a storage area (see site map, fig. 117)
Tues Jan 21 97 13:36 PAGE 4/4
where it will be stacked 6-8 ft high and allowed another heating
cycle prior to being pushed into a large stockpile. Because of the
anticipated lag time in sales as we develop markets for the
finished compost, the storage area will be designed to stockpile as
much as 20-38,088 cu.yds. of compost.
f. Fire protection
Compost will be kept very moist until volatile solids have been
sufficiently reduced to provide a fairly stable and fire resistant
product. Incoming waste wood and ground bulking agent will be
stockpiled in stacks of no more than 580 cu. yds. designed with
access from all sides and adequate separation from surrounding
vegetation and other flammables.
g. Closure
Should the facility ever be closed down, the area will be cleared
of all waste material and unused bulking agent and topdressed with
compost prior to reseeding with native species utilizing the
recommendations of our local Soil Conservation Service. Any
remaining compost will be stockpiled for use in revegatation of the
landfill.
III. IMPROVEMENTS AND EQUIPMENT
There are no buildings planned for this site. A small camper
trailer will be used for an office. The fuel center will consist
of two 500 gallon above ground tanks placed within lined berms
capable of retaining 1,590 gallons.
The equipment found on site will vary as needed but will consist
basically of the following:
1 loader
1 mixing wagon
various pumps and fans for mixing and aeration
1 shaker screen
1 thousand gallon water truck
1 dump truck
1 wood shredder and brush loader
