The contents of this proposal were derived, in part, from conversations with Cathy Hall and Brian Pcttet and associated emails. Weaver Boos has divided this effort into five tasks to assist PC, in no padicular order, as follows: Task 1 Potential Landfill Expansion Task 2 Water Treahnenl Syslem Pro-Forma Update Task 3 Leachate Investigation � Task 4 EDOP Follow-Up Task 5 Aerial Mapping Task 6 Volnmetric Calculation The tasks listed above are discussed in detail wilhin the Collowing paragraphs. SCOPE OF WORK Task 1 — Potential Landfill Expansion At a meeting on June 5, 2013, a general discussion was l�eld with respect to expanding lhe PCLF. The intent of such an expinsion was to, in part, expand the area on the upper portion of the landfill (northwes[ landfill footprint portion). Heartland L,nvironmental (Heartland) will khen use this nrea for compost and aggregatc proccssing. T'he intent of flus effort is to present PCLP administration and other County adminis[ration a conceptual plan prior to October 1,2013. To accomplish this conceptual design, Weaver Boos will perCorm the following subtasks prior to this onsitc presentation: ° ; � � Weaver Boos Consultants F:IADAdNFRKA'GYRVROPOSIL5110IJENGINEER5VC5NR0£tlSAL�OC � 6/IB/13 � I I ��/ � , Subtask 11 -Revicw Coverning Documents PCLF has various goveming documents which an expansion would need to comply with. These documents inc(ude: • Public 7one District Master Plan Amendment and site plan review o Colorado Deparhnen[of Public Health and Gndvonmen[(CDPHE)Regulations • Surrounding landowner concems Subtask 1.2 -CDPHE Scoping Meeting The potential expansion would require a Certificate of Designation amendment and technical revicw by CDPHE. Therefore, Weaver Boos would propose an initial scoping mee6ng comprised of PCLF, Weaver Boos aud CDPHE, to discuss CDPHE's needs and potential concems with respecNto a landfill expansion. At the conclusion of this meeting, Weaver Boos would generate a memorandum of understanding fot distribution for PCLF use. SuUtask 1.3-PCLF Expansion Layaut After PCLF has approved the memorandum of undcrstanding,Weaver Boos will generate a series of plan drawings showing various options to PCLF for landfill expansion. Weaver Boos will take into account, Heartland's desire, after approval from PCLF, to generate a 25 acre yvorking surface on the north end of the landfill, as well as other design criteria generated during the scoping meeting. Weayer Boos will evaluate expansion options only withiu the PCLF property boundary and adjacent to the existing pemutted landfill footprint. Subtask 1.4 -PCLF Administrative Presentatiun As part of this task, Weaver Boos will be available during A predetermined meeting date onsite, to answer questions tq PC administration about the proposed expansion. Weaver Boos will review the proposed expansion op[ions with PC stafP, as well as discuss concems or poteotifi] limiting project factors. � Task 2—Water Treatment System Pro-Forma Update In November of 2011, Weaver Boos completed a Liquid waste processing Pro Porma conceming the handling of approximately 1.5 million gallons, with ability to scale to 2 million gallons of septic and port-o-le[ waste at thc landfilL This Pro Forma identified various options for accepting this waste stream. One option identified was a system by Quanics, Inc. As part of this task, Weaver Boos is proposing to update this option within the Pro Forma for PCLF. Also as part of this task, Weaver Boos will present any additional or changed information with respect to the proposed onsite system. Weaver Boos will also review the location of such an onsite system, along with the pros and cons with constructing a system either above or below ground.

I During a recent site inspection, it w3s noted that there was a pool of liquid with a surface � area of approximately 8 feet by 8 feet within the lanilfill footprint. It is the desirc of i PCLF to investigate tlus pool to better understand what may be happening at the landfill. � Weaver Boos is proposing that this pool be tested against Appendix I pazameters along � with sounding the pooPs total depth to detecmine a bottom elevation. Weaver Boos � understands that PCLF will sample the leachate and send to a laboratory for testing. ! Weaver Boos will perform the sounding of the leachate pool. j Additionally, Weaver Boos understands ttiat PCLF believes there may be a conuection I between the recent recharge of an existing stormwater pond nearthe landfill access road to landfll leachate. PCLF suspects that the recharge may be the result of landfiil leachate from an unknown source. 'Po investigate this, PCLF will sample the pond for the same parameters as listed above for the pool. Weaver Boos wIll obtain the elevation of the , liquid surface at the stormw�ter pond and leachate pool as part o£ an investigation analysis to determine any potenfial correlation. It should be noted that it may not be , possible to draw a correla[ion betweeu the leachate pool and the stormwater pond through analytical results. Weaver Boos will use the in£ormation from the testing and sounding to develop suggestions to address the leachate pool. To complete this, Weaver Boos will provide written conceptua] idcas for further considerarion including any suggested fiuther investigation. . Weaver Boos believes that this will serve as only a preliminary.investigation and further investigation of these two situa[ions may be neecled. In other words, the source of the liquid in the pool and the stormwater pond may be from two totally separate areas and it may not be possible to determine the potential source, given the geology and design of the landfill. In addirion, if a remediation d'uection is taken, the potential remediation may , be required on separate but parallel lasks. Task 4— EDOP Follow-Up Under this taslc, Weaver Boos will respond to CDPHE comments, as needed,based upoo the 2012 Engineering Design and Operations Plan (EDOP) submittal. It is�'Veaver Boos' understanding that at this time CDPHE has provided review of this EDOP snbmittal, based on written comments provided in a letter dated March 26, 2013. Task 5—Aerial Mapping For this task, Weaver Boos will provide thc management and coordinafion for the acria] � mapping service of the landfill. Weaver Boos will solicit proposals and subcontract out aerial mapping. Weaver Boos will have the property area mapped, �vhich encompasses approximately 250 acres. This task inclddes two 22 inch x 34 inch color photos with'contour overlay. � . �Veaver F3oos ConsWtants F:uawmrmr�vcNrnraoraueszoiiervcrrveEasrcstrROros+�oec ld18/13 � � 3 I I _ - �`'�, ., Weaver Boos, at this time,has made an allowance for High County Engineering to place three aerial tnrgets on the landfill for this task. Task 6—Volumetric Calculations This task entails ptoviding volumctrics and sur£ace areas for lwo separatc elevations at the landfill. During the meeting on June 5, 2013, Heartland had [he desire to understand the remaining permitted volume of airspace below the 7640 and the 7660 contour interval.
