Categorical Exemption

Cal. Code Regs., tit. 14, Sections 15000 -15387; CEQA Guidelines Sect. 15301; 15302; 15304; 15311

Class 1 - Existing Public Facilities Categorical Exemption: The Project consists of operation, repair, and maintenance of existing facilities that involves negligible or no expansion of existing or former use. Therefore the Existing Public Facilities Categorical Exemption applies. (CEQA Guidelines § 15301.) Class 2 - Replacement or Reconstruction Categorical Exemption: The Project consists of demolishment of the existing carbon steel piping and hose assemblies and replacing it with new stainless steel hydraulic tube and compression fittings, and hose assemblies at the existing Energy Dissipating Valve Station and will have substantially the same purpose and capacity. Therefore, the Replacement or Reconstruction Categorical Exemption applies. (CEQA Guidelines § 15302.) Class 4 - Minor Alterations to Land Categorical Exemption: The Project involves no physical alteration to the land, water, or vegetation. The existing Energy Dissipating Valve Station will be used in the same manner after the removal and replacement of valves, piping, and hoses. The Project has no permanent effects on the environment. (CEQA Guidelines § 15304.) Class 11 - Accessory Structures Categorical Exemption: The proposed Project consists of construction, or placement of minor structures accessory to (appurtenant to) existing commercial, industrial, or institutional facilities. Therefore, the Accessory Structures Categorical Exemption applies. (CEQA Guidelines § 15311.) Exceptions to the Categorical Exemptions: None of the exceptions to the Categorical Exemptions apply, as the Project will not: impact a designated, mapped, and officially adopted environmental resource of hazardous or critical concern; result in a significant cumulative impact of successive projects of the same type in the same place over time; have a significant effect on the environment due to unusual circumstances; damage a scenic highway or scenic resources within a state scenic highway; be located on a site which is included on any list compiled pursuant to Section 65962.5 of the Government Code; nor cause a substantial adverse change in the significance of a historical resource. (CEQA Guidelines § 15300.2.)

Other

15061(b)(3)

Common Sense Exemption: This Project is also determined to be exempt based upon the general rule that CEQA applies only to projects that have a potential for causing a significant effect on the environment. (CEQA Guidelines § 15061 (b)(3).) A public agency may determine an activity to be exempt where it can be seen with certainty that there is no possibility that the activity in question may have a significant effect on the environment, the activity is not subject to CEQA. Here, there will be no expansion of existing uses, and the EDV Station will operate in the same manner as it did prior to the Project. As such, it can be seen with certainty that there is no possibility that the activity in question may have a significant effect on the environment, and therefore, the activity is not subject to CEQA.
