Submitted by: CacaLoco Compost Inc. 0256 Flying Fish Rd. Carbondale, Colorado Prepared by: James R. Duke President Submittal Date: January 21, 1997 CacaLoco Compost Permit Addendum for the South Canyon Landfill, Garfield County, Colorado. I. GENERAL DATA • a. Title and Names: 'rues Jan 21111117 13:35 PAGE 2/4 CacaLoco Compost Inc. (For Tadco Inc., South Canyon Landfill) 0256 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 B) 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 map, 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 diuersion provided by the road on the other side to provide complete diversion of potential runoff from further up the drainage. (site map, fig. #3) 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 2 17 13:35 PAGE 3/4 The active compost area will consist of approximately 8.5 acres of recompacted native material. (site map, fig. #5) 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 6Y. 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 100,088 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 lined 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 48 CFR 503 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 538 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 217 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 20-38,008 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 euer 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 Conseruation 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 508 gallon above ground tanks placed within lined berms capable of retaining 1,500 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 Tues Jan 21 97 13:40 PAGE 1/1 • 111 Jim Duke 256 Flying Fish Rd.

The South Canyon Landfill is located in portions of sections 2, 3, 10, and 11, Township 6 South, Range 90 Wes at the bth P.M. This compost facility was constructed over native (non -landfilled) lend, south of the four existing septage evaporation ponds. KRW Consulting, Inc. (KRW) was retained by CacaLoco Compost Inc. (CacaLoco) to perform several constructing verification and construction assistance tasks. in particular, CacaLoco acted as the general contractor and installed the working -pad soil liner and the holding -pond synthetic liner. KRW performed part-time, on-site construction observations, verified the thickness et the working pad`s soil liner by elevation control survey, assisted with the installation of the Hypalone liner in the facility holding pond, collected two post-ccnstr uct:cn soil Ifner samples and had these samples laboratory tested for hydraulic conductivity. A site plan for the constructed features of the CacaLcco Compost Facility as well as a site plan for the South Canyon Landfill are presented in Appendix A, of this document, Page 1 DEC -16 97 10:48 FROM:cDFHE'GRAND JUNCTION 1-970-249-7190 • 2.0 Con serecti_gyr TO: 91970%39727 • CutaL0(.1) Compost May '4, 1997 KRW Project 9702-06 Construction began an February 10. 1997 with the clearing of snow and the stripping of existing vegetation. Once a working pad was cleared, an additional 2 to 2.5 feet of soil was removed from the working pad area and the subgrada graded to the desired slope. This additional soil was stockpiled on the eastern side of the site and later used for the 2 -foot thick recompacted working pad soil liner and isolation berms_ On February 12, 1997, Jerome Gamba & Associates et Glenwood Springs. Colorado surveyed and recorded 5 subgrade elevations on the proposed initials 1/4 acre working pad. This and other survey information are presented in Appendix B of this document. Construction continued by CacaLoco personnel with the placement and compaction of the working pad's soil liner using a vibratory slteepsfoot compactor_ They working -pad liner was placed in 4 to 6 -inch thick lifts, until an average completed thickness of two feet was achieved. On February 26, 1997, KRW performed on-site construction observations of the soil working pad liner, surveyed and recorded elevations al the original five sttbgrade thickness control points, and retrieved a post -construction liner sample from the lower ane foot of soil liner. Soil liner construction was progressing adequately, and as cf February 26th, approximately arse foot of linter had been p!2cad OtJer the working part. Two Shelby tubes were pushed with a Caterpillar 0-8. The tube of the first sample (SC -1) bent, and no sample was retrieved. A second tube was pushed, and sample (SC -21 was retrieved and transported to Soil and Materials Consultants (SMC) laboratories in Arvada, Colorado, for hydraulic conductivity testing. Both liner perforations were filled with bentonite chips, hand compacted and hydrated. The location at sarin p e SC -2 is illustrated on the above mentioned site plan for the constructed features of the CacaLoca Compost Facility, anti the surveying records are included in Appendix B. Results of the hydraulic conductivity testing are presented in Appendix C and are discussed tater in 'Section 3.0 - Summary"_ Page 2 PAGE : 04 DEC -16 97 10:48 FROM:CDPHE'GRAHD JUNCTION 1-970-248-7198 • TO: 919709638727 Cat -at -pm Campbst May 14. 1997 KRW PrOjiCt 9702-05 On March 27, 1997, KRW assisted with the 36 -mil reinforced Hypalono liner installation in the holding pond. KRW also performed a final construction observation of the working -pad sail liner and surveyed post -construction elevation at the original five subgrade thickness control points to verity the final working pad liner thickness, Surveying records are presented in Appendix S. The 36 -mil reinforced HypeInn'a liner, used to line the holding pond, was installed in strict accordance with the manufacture's recommendations. These installation and seaming instructions are attached in Appendix ID. The Hype!ono was delivered to the site in two pieces, a 90 by 42 -foot piece and a 7.5 -toot wide strip approximately 294 feet long. The 7.5 -toot strip was seamed to the 90 by 42 -foot piece on all four of its sides. The final HypeIon. liner dimensions prior to installation in the pond was approximately 105 feet by 57 feet. Prior to liner installation, the pond subgrade was walked to verily that no sharp or protruding objects existed thatcould damage the finer. After all the seaming operations were completed and ail the seams checked for quality, the entire piece was moved to the pond and anchored inplace with a standard 1 , foot deep by 1 -foot wide anchor trench. Record drawing measurements of the actual lined pond dimensions and depth were recorded_ The final surface of the working pad was relatively smooth and sloped at approximately ti percent towards the holding pond. A 1 -foot ± soil berrn was installed around the east, west. and north sides of the working pad except where a spillway from the working pad to the holding pond was later installed_ This berm will control all runoff from the working pad and direct it to the Hypalons-tined holding pond. Along the south side, a 3 to 4 -foot high berm was improved to divert up -gradient runon around the working pact and lined pond. On April 18, 1997, Shelby tube sample (SC -3) was pushed with a Caterpillar D-8, retrieved and transported to SMC laboratories for hydraulic conductivity testing. This sample is a post -construction finer sample from the upper one foot of the working pad soil liner. The resulting liner perioratior, was tilted with bentonite chips, hand compacted and hydrated. The location of sample SC -3 is illustrated on the site plan. A discussion of the hydraulic conductivity testing results are presented below in Section 3 0 - Summary. The actual laboratory results are presented in Appendix C.

Two hydraulic conductivity tests were t4'Jr' performed on post -construction soil samples. The tlrst sample from the lower one foot of liner, exhibited a hydraulic conductivity (permeability rate) of 9_g X14-fi cm/sec, a• t 1‘5 The second sample from the upper one toot of liner exhibited a hydraulic conductivity of 1.5 X10-8 cm/sec. This equates to an average hydraulic conductivity for the constructed soil lined working pad of 4.5 X1043 cm/sec. The working pad hes an average slope of 11-3 percent towards the holding pond. The holding pond is lined with a 36 mit reinforced Hypalon° liner. The Hypalon6 is secured in an anchor trench around the perimeter of the pond. Between the working pad and the holding pond is a HypalonP- lined spillway or ramp which allows any liquids draining from the working pad to be directed into, and only into, the hording pond. the holding pant has a brim lull capacity of 90,655 gallons. One foot of freeboard in the holding pond is recommended:'- This freeboard will allow for reserve storage volume in the event a significant rainfall occurs, when the pond is at its recommended capacity. With one toot of freeboard, the usable pond capacity is 65,915 gallons. Drainage is controlled by the installation of berms around the working pad. the sides of the spillway, and perimeter of the holding pond. Precipitation that fails on the working pad or spillway will flow to the holding pond and be retained there_ Up -gradient or side - gradient drainage will be diverted around the working pad, spillway and holding pond by way of these berms and continue in it's pre -construction paths.
