Site work for a municipal facility in Eureka, California. Completed plans call for site work for a municipal facility.

The Cummings Road Landfill (CRL or Facility) operates a landfill gas collection and flare system (gas-extraction system). Because of diminishing landfill-gas generation rates, CRL now operates the gas-extraction system intermittently based on methane and oxygen concentrations and requires the ability to monitor and record the flow rates, temperature, pressure/vacuum as well as methane, carbon dioxide, and oxygen concentrations. HWMA also needs the flow/temperature/pressure/gas concentration readings to be integrated into the existing Fleetzoom recording system so that real time data is recorded and can be viewed remotely. All questions shall be submitted in writing to the above contact either by email no later than 3:00 PM Friday, May 9, 2025. Responses will be provided by 3:00 PM Friday, May 16, 2025. 1.
