I request that this letter be distributed to the full board of Supervisors.

Members of the Sonoma County Board of Supervisors,

Two very large lithium-ion Battery Energy Storage Systems are proposed to be sited very close to Petaluma.

The first, the Borealis Energy Storage Project of 300 Megawatts, Permit Sonoma Planning Project PLP22-0025, is planned for a site adjacent to the Petaluma Adobe State Historic Park.

The second, the Bolero Corporation project of 200 Megawatts, Sonoma County Planning Project PLP22-0005, is planned for a site adjacent to the Pacific Gas and Electric substation at the corner of Frates Road and Old Adobe Road.

The two lithium-ion Battery Energy Storage Systems pose significant hazards to residents of Petaluma. These hazards deserve full investigation and public discussion.

I request that the Sonoma County Board of Supervisors go on record requesting a full EIR for each of these projects.

Respectfully,
