Notice of Exemption

Exempt Status
Categorical Exemption
Type, Section or Code
Cal. Code Regs., tit 14, § 15301
Reasons for Exemption
California Code Regs., tit 14, section 15301 exempts 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. The project involves design, engineering, and economic analyses of concrete wind turbine tower designs and manufacturing. Prototype concrete tower sections (5-meter height and 2-meter diameter) will be fabricated using a robotic arm and 3D printer and will then be tested at an existing research testing civil engineering laboratory or manufacturing facility. The proposed project will have no significant effect on the environment and will involve negligible or no expansion of current or former use of the existing facilities and is therefore exempt.
