design landfill gas collection and treatment systems

November 14, 2017

Most often, landfill gas system design is added to an existing landfill cell, but the co-authors of this article explain the benefits of  considering the LFG system during the landfill bottom liner design process. Doing so during the early stages of the landfill’s life, make it possible to improve collection efficiencies, lower operating costs, and save time in the future.

Continue to the full article, Planning Ahead for the Bottom Liners, published in MSW Magazine’s November 2017 issue and learn about the co-authors from Sarasota County, Florida Public Utilities and SCS Engineers.

The clock is ticking even though some issues remain unresolved. Landfill owners should maintain close contact with their state/local regulatory authority regarding the status of the regulator’s state implementation plan, due by November 2017.

EPA recently established expansive new air rules affecting MSW Landfills. Implementation of the new rules places new responsibilities on both the regulated community and regulators alike. However, some of these responsibilities are unclear and have created unresolved issues that should be addressed in close consultation now with your state/local regulatory authority.


For example, if a landfill is “new,” the facility is now subject to NSPS Subpart XXX, which is fully effective. A design capacity and NMOC emissions rate report should already have been submitted.


If NMOC emissions from a facility exceed 34 Mg/yr, then the landfill will need to submit a GCCS design plan within 12 months of the date of exceedance and install and operate within 30 months (no later than May 2019 for those triggering with the promulgation of the rule). If a landfill is an “existing emissions source,” it will be subject to the new EG rule (Subpart Cf).


Landfill owners should maintain close contact with their state/local regulatory authority regarding the status of the regulator’s state implementation plan, due by November 2017. That state implementation plan will prescribe the required compliance dates for an existing landfill, likely to be no later than the 2018/2020 time period. In either case, owners should become familiar with the rule and stayed tuned as compliance guidance evolves to address the unresolved issues.
