A new methane emission rule has been announced for active and closed solid waste (MSW) landfills in the state. All affected landfills must meet the requirements starting July 1, 2024. The new rule includes specific requirements for surface emissions monitoring (SEM) that mirror those of the US EPA and other states. While the rule increases accountability for methane emissions, it could also lead to increased labor costs and safety concerns for technicians due to increased inspection time. Sniffer Robotics, LLC, has introduced the SnifferDRONE, an unmanned aerial system (UAS) that can perform SEM inspections 50% faster, reducing technician exposure to hazards and improving methane detection effectiveness. The method, utilizing the UAS, provides confidence in inspection through greater process control, data management, and professional reporting. Industry leaders in the state have already begun using the SnifferDRONE for landfill emission monitoring in 2023.
