How to manage the unknowns of landfill gas well installation – plan for the worst, expect the best

Drilling landfill gas (LFG) collection wells keeps landfills in compliance, but it can potentially create other issues. Since LFG wells are installed into a waste mass that contains many unknowns, drilling wells can potentially result in accidental penetration into baseliners or puncture of existing piping. Damage like this may lead to environmental compliance issues and…

Hot landfills – prevention, detection and solutions

The issue of hot landfills has become a significant challenge to the waste industry over the last ten years. When a landfill’s temperature begins to elevate significantly, rapid response is necessary to minimize impacts to the public and costs to the owner. Each hot landfill is unique and I wanted to share the experience gained…

What is an infrared camera – and how can it help me?

Imagine seeing someone looking down the lens of what appears to be a 1980s video camera pointed toward your facility. You may not know whether to laugh or call the cops! Believe it or not, this may really happen to you and I was once one of the regulators who did this. Prior to my…

Solar energy generates revenue from closed landfills

Let’s face it – there are only so many revenue-generating uses for a closed landfill. Unless you generate enough landfill gas (LFG) to make power generation or other LFG use feasible, the closed landfill sits not generating any revenue for at least 30 years. That’s why siting a solar array on a closed landfill can…

How to avoid prematurely committing a landfill to NSPS compliance – carefully plan sampling to avoid positive bias

Landfill operators must conduct Tier 2 testing to calculate a landfill’s non-methane organic compound (NMOC) emission rate if the design capacity is greater than 2.5 million megagrams (MG). Favorable results of a Tier 2 test allows landfills to opt out of the New Source Performance Standards (NSPS) requirements to install and operate a gas collection…

Coal combustion residuals – what should you consider before accepting them?

Unless you live under a rock, you know about the new CCR Rule, a RCRA Subtitle D Non-Hazardous Waste Rule that covers coal combustion residuals (CCRs). These include fly ash, bottom ash, boiler slag, and flue gas desulfurization (FGD) waste. I thought it would be interesting to share my thoughts on how the rules are…

Biogas energy recovery at a California wastewater treatment plant – Lessons learned

I recently worked on a very interesting project in California to design a biogas energy recovery system for a wastewater treatment plant (WWTP). The system recovers nearly 100 percent of the methane produced from anaerobic digestion of wastewater sludge and conditions it for heat and power generation and transportation fuel. The design integrates a BioCNG™…

New NSPS Subpart XXX – Initial thoughts on how to comply and report

The air compliance team I work with has been working very closely with leaders across the solid waste industry to discuss a consistent approach as we all begin implementing the NSPS Subpart XXX rules. Initial reporting was due on November 28, 2016 for the Initial Design Capacity Report and the NMOC Emission Rate Report and…

Small changes matter when it comes to improving landfill gas quality

How many alarm bells go off in your head when monitoring data indicates a significant drop in landfill gas quality, especially if you are supposed to use the gas in a beneficial reuse facility? And what can you do about it? I have an interesting story about a Wisconsin landfill that illustrates that small changes…

Spray applied membranes – tips for effective use in landfill/brownfields redevelopment

Spray-applied membranes are typically the gas membrane barrier of choice to prevent vapor intrusion into buildings during landfill/brownfields redevelopment because they are so easy to apply around penetrations. But I have learned from experience (the school of hard knocks) that there are some real world pitfalls of using spray-applied membranes and achieving an effective methane…
