SURFACE EMISSIONS MONITORING

for Compliance

Sniffer Robotics provides manual surface emissions monitoring (SEM) used to monitor landfill gas emissions in compliance with New Source Performance Standards (NSPS) and 40 CFR Part 60, Subparts WWW.  Sniffer Robotics also provides manual services to comply with new emission guidelines specified within Subpart Cf and Standards of Performance for Municipal Solid Waste Landfills under 40 CFR Part 60, Subpart XXX (New NSPS).

​

Sniffer Robotics technicians are required to walk the landfill to visually inspect the site, while monitoring fugitive gas emissions with a hand-held detector.  The methane emission concentrations are measured and manually collected using a detector compliant with Method 21.  Emissions above 500 ppm are inspected and reported.  Subsequent inspections are required for 10-day, 10-day and 30-day in the event exceedances are found on the initial inspection.  A formal compliance report is provided for operational purposes and regulatory compliance purposes.

​

GPS coordinates with emissions data may also be captured and provided in SnifferVIEW™, providing a visual representation of the areas inspected and the actual methane gas concentrations recorded.  SEM data can further be combined with additional sensing to provide a complete landfill cover assessment.
