Bridgeport Road Shop thermal Biomass Project

NOE - Notice of Exemption

Document Description
The goal of this "Mono County Thermal Biomass Project" is to sustainably utilize biomass resulting from activities associated with reducing catastrophic wildfire risk, improving forest habitat and resilience, treating forest pests, and restoring meadow structure and function. Remove and replace the current, outdated, and inefficient boiler system at the County Road Shop and parks/facilities building Bridgeport with a new 2.5 MMBtu/hour or less thermal biomass boiler system. The mechanical room will be retrofitted to accommodate a fuel hopper and water storage tank, and existing piping and pumps will be reconfigured as necessary for full system integration. Staff will be fully trained in system operations and maintenance, and a new wood chip storage building of up to 960 square feet will be constructed on-site to ensure one weed of fuel supply. The thermal unit would consume a maximum of 367 bone dry tons (BDT) of biomass a year.

The unity will be compliant with air quality regulations as required by the Great Basin Unified Air Pollution Control District. The new wood chip storage building of up to 960 square feet is an accessory structure to the Road Shop and is not larger than a typical two-car garage.
