For years, Wisconsin landfills have relied on compliance with the storm water (stormwater) management requirements in the Chapter NR 500 code series to achieve compliance with the NR 216 storm water standards. Effective June 15, 2016, the Wisconsin Department of Natural Resources (WDNR) changed their policy, and now requires landfills and associated non-commercial borrow sites to obtain separate industrial storm water permit coverage.

Vertical liquids addition systems have been used at municipal landfills as a leachate management method and to enhance biostabilization of waste. Drawbacks of these systems include a limitation on pressurized injection and the occurrence of seepage. A novel vertical well system that employed buried wells constructed below a lift of compacted waste was operated for 153 days at a landfill in Florida, USA. The system included 54 wells installed in six clusters of nine wells connected with a horizontally oriented manifold system. A cumulative volume of 8430 m3 of leachate was added intermittently into the well clusters over the duration of the project with no incidence of surface seeps. Achievable average flow rates ranged from 9.3 × 10−4 m3 s−1 to 14.2 ×
10−4 m3 s−1, which was similar to or greater than flow rates achieved in a previous study
using traditional vertical wells at the same landfill site.

While not a new concept, the authors examine the advantages and disadvantage of landfill mining as metropolitan areas grow larger and nearer to landfills, and as the landfills are filling up faster despite recycling programs.

The unique nature of landfill decomposition and the demands of safety, environmental compliance, and energy recovery create a dynamic environment under which Landfill Gas (LFG) management systems perform. These conditions place long term stresses on system components and increasingly challenge the ability of operators to effectively and efficiently manage the collection and control of LFG in a cost effective manner.
This case study concerns an aging LFG system located in northern Virginia nicknamed the I-95 Landfill. Operation and maintenance had become onerous and expensive as the system aged. Plans to evaluate, redesign, and rebuild the system with the intention to simplify operation and optimize performance while reducing lifecycle operation and maintenance costs were implemented. This paper presents the site history of the I-95 Landfill along with the approach from system evaluation findings, the design recommendations, construction, and the lessons learned.
Survivability of leachate collection pipes depends upon the gravel placed on all sides of the pipe. Proper placement of gravel around the pipe and the granular soil material over the completed pipe/gravel/geotextile burrito is of significant importance in the protection of the leachate collection pipe.

Do you have NSPS or EG sites per the new definitions of “new” and “existing”?
Does your EG site have any upcoming planned or permitted expansions, or will it be commencing construction on an expansion permitted after July 17, 2014?
Will you need to submit/resubmit Design Capacity and NMOC reports to establish your sites status as subject to the new NSPS? Over, or under 34 Mg/year of NMOCs?
Are you a candidate for Tier 4? In the closed landfill subcategory?
For EG sites contact the SCS state representative by sending a request to
SCS Engineers will be publishing Pat Sullivan’s Technical Bulletin Summary of Final NSPS/EG Rules for Landfills as soon as it is published in the federal register. Meanwhile, please contact your SCS Project Manager or for answers to your questions or advice.

Jeff Marshall, PE, SCS Engineers will be presenting the topic of Hydrogen Sulfide Issues at CCR and MSW Co-Disposal Sites during the EREF and NWRA sponsored Coal Ash Management Forum in July.
The co-disposal of municipal solid waste and coal combustion residuals – particularly flue gas desulfurization (FGD) material – poses a significant concern regarding the generation of hydrogen sulfide gas. Hydrogen sulfide has an exceptionally low odor threshold, and can pose serious health concerns at higher concentrations. This presentation will identify the biological, chemical and physical conditions necessary for FGD decomposition and hydrogen sulfide generation. Recommendations for reducing the potential for FGD decomposition at co-disposal facilities will be presented. Technologies for the removal and treatment of hydrogen sulfide from landfill gas will also be addressed.
Jeff Marshall, PE, is a Vice President of SCS Engineers and the Practice Leader for Environmental Services in the Mid-Atlantic region. He also serves as the SCS National Expert for Innovative Technologies. He has a diversified background in environmental engineering and management, with emphasis on the chemical and human health aspects of hazardous materials and wastes. Mr. Marshall’s experience with hydrogen sulfide, odors, sulfate decomposition in landfills, and ash issues includes scores of projects dating back to the 1980s.
