  • 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.

  • 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.

  • 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.

  • EPA's Guide for Industrial Waste Management
    Guide for Industrial Waste Management Protecting Land Ground Water Surface Water Air Building Partnerships Introduction EPA’s Guide for Industrial Waste Management Introduction Welcome to EPA’s Guide for Industrial Waste Management. The pur- pose of the Guide is to provide facility managers, state and tribal regulators, and the interested public with recommendations and tools to better address the management of land-disposed, non-haz- ardous industrial wastes. The Guide can help facility managers make environmentally responsible decisions while working in partnership with state and tribal regulators and the public. It can serve as a handy implementation reference tool for regulators to complement existing programs and help address any gaps. The Guide can also help the public become more informed and more knowledgeable in addressing waste management issues in the community. In the Guide, you will find: • Considerations for siting industrial waste management units • Methods for characterizing waste constituents • Fact sheets and Web sites with information about individual waste constituents • Tools to assess risks that might be posed by the wastes • Principles for building stakeholder partnerships • Opportunities for waste minimization • Guidelines for safe unit design • Procedures for monitoring surface water, air, and ground water • Recommendations for closure and post-closure care Each year, approximately 7.6 billion tons of industrial solid waste are generated and disposed of at a broad spectrum of American industrial facilities. State, tribal, and some local governments have regulatory responsibility for ensuring proper management of these wastes, and their pro- grams vary considerably. In an effort to establish a common set of industrial waste management guidelines, EPA and state and tribal representatives came together in a partnership and developed the framework for this voluntary Guide.

  • 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.
