On Might thirteenth, the Washington State Division of Ecology introduced a brand new methane emission rule (Chapter 173-408 WAC) for lively and closed stable waste (MSW) landfills of their state. All affected landfills should meet the necessities beginning January 1, 2025.
Whereas the necessities of the brand new rule are prolonged, and can impression many elements of landfill operations, this announcement is narrowly targeted on new necessities particular to floor emissions monitoring (SEM). Washington’s new necessities mirror these of California, Oregon and Maryland, requiring:
- SEM inspection carried out by a subject technician traversing in a serpentine path with not more than 25-ft spacing between the inspection paths.
- Instantaneous and built-in floor emissions reporting.
- SEM operations restricted to a most common and instantaneous wind velocity and can’t be carried out sooner than 72 hours after precipitation.
Whereas the brand new rule will drive better accountability for methane emissions, it is going to additionally result in elevated labor prices and technicians’ publicity to hazards by rising their inspection time threefold. Washington has alleviated these issues by permitting using a drone to carry out work that will in any other case be carried out manually. The drone (an unmanned aerial system known as the SnifferDRONE™) performs the inspection 50% sooner, thus decreasing technician’s publicity to hazards, whereas bettering the effectiveness of detecting methane emissions and their leak sources.
The US EPA was the primary to approve using an unmanned aerial system (UAS) for this function as outlined in Different Check Methodology 51 (OTM-51). Washington has built-in OTM-51, with modifications, of their new rule. The strategy, using the UAS, offers confidence in inspection by way of better course of management, information administration, {and professional} reporting.
Trade leaders in Washington started utilizing the SnifferDRONE for landfill emission monitoring in 2023. These early adopters acknowledged the chance to enhance the setting and their operations. We congratulate these leaders for his or her imaginative and prescient and thank them for making a distinction.
We stay up for persevering with our work within the state and past to enhance the strategies for detecting and accounting for landfill methane emissions.
