Reasons for Exemption
California Code of Regulations, title 14, section 15301 ("Existing Facilities") provides that projects which consist of the operation, repair, maintenance, permitting, leasing, licensing, or minor alteration of existing public or private structures, facilities, mechanical equipment, or topographical features, involving negligible or no expansion of existing or former use, are categorically exempt from the provisions of the California Environmental Quality Act. The project will install the following components in each of 15 existing single family homes: solar photovoltaic (PV) panels to absorb the solar energy and convert it to electricity, commercially available residential lithium-ion battery energy storage to store the electrical energy, power electronic converter to convert DC electricity to AC electricity, electrical panel to provide protection circuit and measurements, and a PQ-CU control box to control the PQ-CU (solar + battery) technology. Installation of solar PV panels will be on the rooftops of existing homes; no ground mounts or otherwise will be used. Installation of the battery storage will require minor alterations to the interior or the exterior of the single-family homes or adjacent garages with no expansion of footprint. Specifically, containerized energy storage units will be installed near the electrical panel in or near the existing garage of each home and connected to the home's rooftop solar. The project will not: 1) result in a significant cumulative impact, 2) have a significant effect on the environment due to unusual circumstances, 3) damage resources within a designated state scenic highway, 4) cause substantial adverse change to the significance of a historical resource, or 5) be located on a listed hazardous waste site. For these reasons, the project will have no significant environmental impact and falls under section 15301.
