PW061119-07 Project 2448 Cell 16 Final Cover Exhibit a Scope of Work EXHIBIT A SCOPE OF SERVICES Cell 16 Final Cover Project No. 18-2448 / CIP 51202 The City of Rapid City has determined the need to procure professional engineering services including Preliminary Design Services, Final Design Services, and Bidding Services for the installation and placement of a final cover system and Gas Collection and Control System (GCCS) over the in-place municipal solid waste (MSW) in Cell 16. Basic Construction Services and Expanded Construction Services will be negotiated at a later date as a separate contract. In addition to the Cell 16 Final Cover and GCCS design, the City also has determined the need for professional services for the design, bidding, and construction of litter control netting along the perimeter of Cell 18 with emphasis on the western and northern portion. Services through construction of the litter control netting will be included in this scope of services but will be allocated exclusively to subtasks 1.13, 2.23, and 3.07. Task 4 and Task 5 in their entirety are exclusively reserved for the litter control project component. It is anticipated that the Cell 16 Final Cover improvements will include the following: 1. Preliminary final cover system design which will incorporate current permit requirements and South Dakota Department of Environment and Natural Resources (DENR) standards. 2. Analysis of current fill grades and relationship to final permitted contours. A ground survey will be required to determine if Landfill Operations has reached or exceeded permitted waste grades. 3. On-site geotechnical investigations for clay materials and borrow areas. 4. Integrating the proposed final cover system into the existing capped cells located to the north and east; also ensuring the future cells to the south may be filled adequately and efficiently against the proposed capped cells. 5. Evaluation of the existing asbestos monofill disposal site and integration into the closure plan. 6. Establishing existing and future maintenance access roads to be used by Landfill Operations personnel including improvements as necessary to address traffic movements and drainage. 7. Construction phasing required to keep the Landfill operating efficiently, protecting the public safety, and maintain Landfill Operations within permit requirements. 8. Drainage improvements along the main access road to reduce roadway overtopping and erosion issues. 9. Methane Gas Collection System design and incorporation. 10. Site stabilization and revegetation design. It is anticipated that the Litter Control improvements will include the following: Page A - 1 1. The Consultant shall provide a preliminary netting and pole material evaluation and recommendations. The location evaluation will be discussed in a technical memorandum or Conceptual Design Report specific to the litter netting project. Upon completion of this task, the netting material evaluation will be narrowed down to the preferred materials before completing subsequent specifications and drawings. 2. The Consultant shall perform a preliminary semi-permanent litter netting location analysis and a temporary litter netting analysis. The semi-permanent litter netting is envisioned as being generally located on the perimeter of Cell 18 and the temporary litter netting is envisioned as the portable units currently utilized by Operations that may be set up on the leachate berm along the eastern side of Cell 18. The location analysis options will be discussed in a technical memorandum or Conceptual Design Report specific to the litter netting project. Upon completion of this task, the netting layout will be narrowed down to one preferred design before completing subsequent specifications and drawings. The litter control netting analysis shall also consider the concept of being able to reset or reuse components of the litter control system on the future cell expansions. 3. The Consultant shall provide the City a complete design, bidding, and construction project package for construction of the litter netting and also shall provide construction administration services for the litter control netting project to be installed along the perimeter of Cell 18. FMG was selected as the primary Consultant through the City’s selection process to provide Engineering Services for the overall Landfill Permit 2018 project and the above described tasks for the Cell 16 Final Cover; however, it was decided early during contract negotiations to enter into two separate Professional Services contracts. Therefore, Cell 16 Final Cover Tasks 1, 2, and 3 are included in this agreement. It is anticipated that a contract amendment for the Task 4 Basic Construction Services and Task 5 Expanded Construction Services will be negotiated prior to construction of the Cell 16 Final Cover and GCCS project construction. Negotiations are anticipated to occur sometime around October 2019. The level of effort and specific tasks for each phase of work is described in greater detail in the following sections. TASK 1 - PRELIMINARY DESIGN SERVICES: This task consists of all services necessary to take the project from beginning through the Preliminary Design submittal stage and may include the following itemized services: 1.01 Kick-off Conference: The Consultant shall meet with City staff to detail project concept and scope. The Consultant shall prepare an agenda, take minutes, and distribute minutes. 1.02 Review background information listed in the RFP, and any other resources as necessary. Background information includes City of Rapid City GIS maps, 2013 Solid Waste Permit, Title V Air Quality Permit, plans of existing facilities, and any operational plans or master plans on file for the facility. 1.03 Perform site surveys: This task consists of services required to perform a topographic survey for design. A portion of this tasks fee, in the amount of $4,000.00, will be billed as a lump-sum fee. A. Perform site surveys sufficient for design plan preparation. The route and topographic survey shall be in NAD 83 (2011) NAVD 88 South Dakota State Plane South Zone. One call locating service will be notified for marking of existing utilities. This task also Page A - 2 includes a Pre-Construction Survey to confirm final grades once waste placement operations are complete. This will provide an updated topographic survey as close to construction as possible to provide final quantities of required fill and cover materials after final waste elevations have been reached and any settlement of the waste has occurred. B. Perform initial site topographic survey for design. This task during waste placement to assist City with waste placement activities to ensure permitted final cover contour elevations are not exceeded and airspace is maximized. Drone Survey. Initial topographic survey will include a high definition aerial image for use in planning, design, and construction. This task does not include any engineering calculations or design. This task will be billed on a lump-sum fee basis by percent complete. 1.04 Determine Locations of Existing Infrastructure: A third-party locator may be required. If required, this performed by the City or contracted by the City. 1.05 Existing Leachate Collection System Evaluation and Recommendations: This task shall include an evaluation of the expected leachate volumes anticipated and review of Operations data to compare to the actual volume collected. The lift station and pump will also be reviewed to determine adequate function for expected leachate volume after Cell closure. Current maintenance and condition of the system will be reviewed with Operations to determine if work is necessary prior to Cell closure. This task does not include any engineering calculations or design. This task will be billed on a lump-sum fee basis by percent complete. 1.06 Landfill Gas Collection and Control System (GCCS) Expansion Design. This work shall include the work to design the GCCS system for Cell 16 and shall coordinate with the phasing of the placement of the final cover system. A. A portion of the background information review will be completed on a lump sum fee basis by percent complete. B. This portion of Task 1.06 will include the following subtasks and shall be billed on a time and materials basis. B.1 The remaining portion of the background information review will be completed and billed on a time and materials basis. B.2 Prepare an Overall GCCS Design to make certain that the proposed system in Cell 16 is adequately sized to convey the landfill gas (LFG) generated. Note that this scope of work does not include the development of any GCCS Overall Master Plan/LFG Phasing Plans or the evaluation of any existing equipment or infrastructure currently in place. The scope of services does include evaluation of the pipe network that will need to be installed in Cell 16 as part of the capping project. B.3 Reimbursibles: This line item includes expenses related to travel. This item does not include hourly labor. The estimate for this task assumes one trip to the site and includes additional printing and shipping costs. The estimate for this item is on a not-to-exceed basis. Unused funds in this item shall not be available for reallocation to other tasks. Page A - 3 The City is anticipating that the GCCS sub-consultant for this project will likely be under contract with the City for GCCS assistance and evaluation of GCCS components not directly related to the Cell 16 Final Cover project. It is recognized that better efficiency in design and project coordination should be achieved utilizing the same sub-consultant. Work that has been included in separate scopes, proposals, and/or contracts is not part of this contract. If work required for the Cell 16 GCCS system design has been completed under a separate contract, it will not be billed under this contract. Conversely, if work included in a separate scope or contract has not been completed and is required for Cell 16 GCCS system design, it is not part of this scope and would be additional work.

  • Municipal Solid Waste Landfill Operation and Management Workbook
    MUNICIPAL SOLID WASTE LANDFILL OPERATION AND MANAGEMENT WORKBOOK Revised April 2018 Preface In many ways, constructing, operating and maintaining a municipal solid waste landfill is similar to constructing, operating, and maintaining a highway, dam, canal, bridge, or other engineered structure. The most important similarity is that landfills, like other engineered structures, must be constructed and operated in a manner that will provide safe, long-term, and reliable service to the communities they serve. Proper design, construction, operation, monitoring, closure and post-closure care are critical because after disposal the waste can be a threat to human health and the environment for decades to centuries. This workbook is intended to provide municipal landfill operators and managers in Wyoming with the fundamental knowledge and technical background necessary to ensure that landfills are operated efficiently, effectively, and in a manner that is protective of human health and the environment. This workbook contains information regarding basic construction and operation activities that are encountered on a routine basis at most landfills. The basic procedures and fundamental elements of landfill permitting, construction management, monitoring, closure, post-closure care, and financial assurance are also addressed. The workbook includes informative tips and information that landfill operators and managers can use to conserve landfill space, minimize the potential for pollution, reduce operating costs, and comply with applicable rules and regulations. In addition to this workbook, operators and managers need to become familiar with the Wyoming Solid Waste Rules and Regulations applicable to municipal solid waste. The DEQ also provides numerous guidelines that may help understand regulatory requirements in more detail.

  • Decommissioning Or Relining Domestic Wastewater Ponds
    Decommissioning or Relining Domestic Wastewater Ponds Requirements and Procedures Purpose The purpose of this fact sheet is to describe regulatory requirements and provide guidance for the decommissioning or relining of domestic wastewater treatment ponds. These requirements may include (but are not limited to): • removal and disposal of biosolids • sealing/capping of any groundwater monitoring wells • proper demolition, capping, and elimination of treatment components Permittees with a domestic wastewater treatment pond system that are eliminating the use of ponds (either through replacement with a new treatment system, or closure of the treatment system altogether) cannot abandon the ponds “as is”, due to potential safety, environmental and human health hazards. Biosolids accumulated on the pond bottom contain a number of pollutants, nutrients, and pathogenic organisms that must be handled properly before abandoning or re-using the structure. When are Ponds Decommissioned? After domestic wastewater ponds cease to receive wastewater for treatment and all the flows are conveyed to another facility, the biosolids in them are subject to one of the following rules and must meet requirements for use or disposal. Rules and Regulations that Apply • 40 Code of Federal Regulation [CFR], ch. 503 Standards for the Use of Disposal of Sewage Sludge. This rule covers the options for the use or disposal of biosolids that are based on risk assessments done by the Environmental Protection Agency. This rule forms the basis of Minn. R. ch. 7041 for land application. • Minn. R. ch. 7041 – Biosolids Management Rule. This rule covers biosolids that are applied to the land for treatment and beneficial use. It also applies to the biosolids in a wastewater treatment pond once it ceases to receive wastewater.

  • FACT SHEET – Alternative Final Covers for Low-Risk MSW Landfills
    FACT SHEET – Alternative Final Covers For Low-Risk MSW Landfills Nevada solid waste regulations (NAC 444.6891) require that final covers for MSW landfills be designed to minimize infiltration and erosion. The prescriptive design is a barrier layer consisting of at least 18 inches of compacted low-permeability (1 x 10-5 cm/sec) soil covered by an erosion layer of at least 6 inches of soil capable of sustaining the growth of native plants. In addition to this prescriptive standard, the Solid Waste Management Authority may approve an alternative final cover design that provides equivalent protection from infiltration and erosion. There is a substantial body of evidence which indicates that alternative final cover designs which maximize moisture removal from the cover through the natural processes of evapo-transpiration and runoff can prevent infiltration as well as, or better than, the prescriptive design, especially in arid regions. Additionally, construction of an alternative cover may also cost less at locations which do not have low-permeability soils available. At disposal sites where the risks to public health and the environment are relatively high, a thorough evaluation of an alternative cover design should be conducted based on site- specific information. This process, however, can be time-consuming as well as expensive and is not appropriate at sites with a relatively low risk. Low-Risk Sites and Generic Design The risk of leachate generation and ground-water contamination at some of Nevada’s municipal landfills is very low. For purposes of alternative final cover evaluation, NDEP considers sites with the following characteristics to be low-risk: • groundwater is at least 100 feet below ground surface; • very small, i.e., have disposed less than an average of 2 ton/day or the amount generated by a community of approximately 1000 inhabitants (based on 4.4 lb/person/day generation rate); • have not employed deep waste disposal practices, i.e.

    USE OF LIME-TREATED WASTEWATER SLUDGE-SOIL MIXTURES FOR DAILY COVER IN SOLID WASTE LANDFILLS by Aziz Amoozegar, Department of Soil Science Morton A. Barlaz, Department of Civil Engineering A.R. Rubin, Department of Biological and Agricultural Engineering North Carolina State University Raleigh, North Carolina 27965 Special Report Series No. 16 The research on which this report is based was financed by the Charlotte­ Mecklenburg Utility Department through the N.C. Water Resources Research Institute (Urban Water Consortium) . Contents of this publication do not necessarily reflect the views and policies of the Charlotte-Mecklenburg Utility Department (CMUD) or the N.C. Water Resources Research Institute (Urban Water Consortium) nor does mention of trade names or commercial products constitute their endorsement by either agency. WRRI Project No. 50174, 50175, 50176 January 1995 ABSTRACT Increased quantities of wastewater treatment sludge, coupled with more stringent regulations, make it important to develop alternative strategies for residuals management. The use of a mixture of anaerobically digested, lime-stabilized wastewater sludge (LSS) and soil as a cover material for landfills was evaluated for its physical properties, its effect on refuse decomposition and leachate quality. Laboratory tests indicated that the LSS reduced the density of the LSS-soil mixture while the saturated hydraulic conductivity of LSS-soil mixtures increased with greater fractions of LSS. The presence of LSS at values of 50% and above also increased the water holding capacity of LSS-soil mixtures. There were significant differences in liquid limits and plastic limits between soil only and LSS-soil mixtures. Tests on the effect of LSS-soil mixture cover on refuse decomposition were conducted in 4-liter reactors filled with shredded refuse and operated to accelerate refuse stabilization.
