Municipal landfill design calculations an entry level manual of practice This edition was published in 2009 by Richardson Environmental Solutions & Design, LCC in Lemitar, New Mexico. Where you use a geotextile you must follow the design requirements for geosynthetic materials and using non-woven protector geotextiles in landfill engineering (LFE7). The Environment Agency will accept other types of drainage material but you must demonstrate they are suitable. You must develop a landfill gas management plan based on your site-specific risk assessment. Where you propose to raise any leachate monitoring or extraction point raised progressively at the same time as waste is landfilled, your design and installation method must ensure it stays vertical during and after construction. The Environment Agency will normally follow these 3 approaches: You must complete the replacement of any temporary cap with a final cap within 2 years. Leachate and leachate treatment 2.3.6.

As the site operator you must design and build your landfill to protect the environment. For all size reduced materials you must specify the: The Environment Agency does not consider 300mm rough shred to be suitable for use as UTDAR. This is to check for defects after the leachate drainage layer has been installed and before depositing waste. For example, with part-time supervision. The landfill design package should include plans, specifications, a design report and an operator's manual — all of which are submitted to regulatory agencies. You must remove leachate from the drainage collection system by: You must install a ‘target pad’ in preparation for retro-drilling to replace a failed extraction well or monitoring point. The Environment Agency provides more guidance on raising the base of a site when you propose to deposit waste into water. Read guidance on the design of capping systems in the industry code of practice (LGG 111). They can be loose tipped or baled whole and shredded used tyres. For earthworks, the design and specification must follow the guidance for the specification for highway works. You must use geophysical leak detection on all cells where the artificial sealing liner is a geomembrane. For example, if test results show it will be 6 months before the onset of ultraviolet degradation, you can leave the filter geotextile exposed for that period without further testing. The pipe can be slotted, perforated fully or perforated for two-thirds of its circumference. You must include information to satisfy the recovery test in your construction proposals and CQA plan, or in a separate waste recovery plan. You must submit your risk assessment to the Environment Agency as part of the application process. a discrete area of land or excavation that receives household waste Your groundwater risk assessment must demonstrate that the proposed geological barrier will provide sufficient attenuation to prevent a potential risk to soil and groundwater. The layout of your leachate collection and monitoring wells must allow access for monitoring and abstraction. However your site emergency plan must provide a generic CQA plan for foreseeable emergency works and you must submit a CQA validation report for all emergency works as soon as practicable. The Federal Criteria do not require existing units to be retrofitted with liners. Your CQA plan must include the pass criteria for the proposed DAC material. Guideline Landfill siting, design, operation and rehabilitation Page ii of 34 • ESR/2015/1627 • Version 4.01 • Effective: 23 NOV 2018 Department of Environment and Science Prepared by: Environmental Regulatory Practice, Department of Environment and Science Where you use a mineral (such as clay) as the artificial sealing liner, you must protect it against erosion, weathering, desiccation, vegetation and penetration. Where your design uses a gas collection layer, you must consider its compatibility with other elements of the gas control measures in relation to: Your design must consider possible failure modes, for example: Where you need to use temporary measures to collect gas until the permanent systems can be installed, you must set out your temporary system design in your gas management plan. Where you use a separation geotextile as part of your design, you must specify the material you propose to use and show it will provide suitable separation. The design requirements that you need to meet in your environmental permit application and how to comply with your permit. Brian Guzzone Eastern Research Group, Inc. 2 2 Overview What is a proper disposal site? To be a recovery activity, waste material must be replacing non-waste material that would otherwise be used. Landfills for hazardous and non-hazardous waste must have a leachate collection and sealing system unless collecting leachate is not necessary. You must carry out frequent inspections, monitoring and maintenance for all discharge pipework to make sure it remains fit for purpose. You will need to install a temporary cap where waste is no longer accepted in part of the site and you do not intend to return to that area for more than 6 months. It depends on the depth of waste below the structure and the final height of the structure. You must prepare a specification and CQA plan for all elements of the landfill gas collection and monitoring systems. This guidance does not cover woven geotextiles as they are not commonly used as protectors. ���^�˪�g���5+ؚ֔5t ��-�ri �� You may maintain a temporary cap for up to 5 years where you have confirmed in writing to the Environment Agency that you plan to re-open the site. To get a good filter around the pipe you need to retain approximately 85% of the gravel surround. Buy Landfill Manuals: Landfill Site Design by Environmental Protection Agency (EPA) (ISBN: 9781840950267) from Amazon's Book Store. The Environment Agency will not accept CQA inspectors with only basal lining and capping supervision experience. You must include details of how you will undertake a trial liner on site to verify your mix design. At the end of the day, a suffi-cient amount of cover earth (usually six in.) You must describe how a proposed panel layout for the geosynthetic materials will be determined before the geomembrane is installed. You must follow the design requirements for geosynthetic materials and using geomembranes in landfill engineering (LFE5). Before using the geomembrane and at the start of each shift, you must carry out trial seams. Landfills for hazardous and non-hazardous waste will normally need a permanent surface sealing layer. Find out how to manage the leachate produced by the waste in your landfill. This must be within 2 years of the end of waste disposal as a maximum where: For temporary works, the installation must be subject to in-house management system control. You can only store and use whole or shredded used tyres once the Environment Agency has approved your construction proposals in writing. You must submit your risk assessments to the Environment Agency as part of your permit application. You must make sure migration control is not compromised by landfill gas utilisation. You must provide the manufacturer’s quality control testing and all design calculations within the validation report for the works. You must adopt CQA procedures to document the design, construction and maintenance of the extraction or monitoring point. Your CQA plan must state that only suitably qualified, trained and experienced staff install the geomembrane liner. ��Op/`��L�4���C@[�(���9��{,�N���~���3)� 10 Feb 2013 Guidelines for the design and … This work must be supervised by a suitably experienced third party CQA. Volume 6 User Manual of LACMIS (Landfill Closure Management. A third party CQA engineer must supervise the installation and drilling of retrofitted leachate extraction and monitoring wells. You must refer to the functional characteristics and relevant test methods. The liner you choose must be resistant to a wide range of chemicals over long periods of exposure. You must use suitably qualified, trained and experienced staff to install leachate extraction and monitoring pipework. Capping must take place as soon as possible after the end of waste disposal in a phase or cell.
