Getting a firm handle on a solid waste operation and expenses is a challenge for any solid waste agency manager or landfill operator. It is particularly imperative in this era of “lean and mean” budgets and looming regulatory policy. Doing more with less is the watchword for most operations across the country still reeling from the financial impacts of the Great Recession.
SCS Engineers has created a package of articles to help you identify if your landfill, landfill gas, or solid waste operation is ready for 2017. We hope this useful guidance will help you plan for the upcoming year. SCS professionals are always available to answer questions and provide advice. Find the office or SCS professional nearest to you by clicking on one the links here: Offices and Professionals.
Download, print or share this package by using the download button under the articles or by using the navigation at left. The package includes the following information written by SCS National Experts:
Article in Waste360: explains who’s impacted and how to begin managing the costs.
SCS Technical Bulletin: a digest of hundreds of EPA regulatory policy into the information and timelines to act on now.
Article: strategic financial planning to support infrastructure costs.

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.
