Document Description
The purpose of the proposed project is to replace aging infrastructure at the Shastina WWTP, improve the treatment process, and ensure compliance with State Water Resources Control Board Waste Discharge Requirements (WDRs). Improvements include the following: installing a new mechanical screen and headworks structure at the location of the existing headworks, a new baffle at Pond 1 to improve the flow of water, high-density polyethylene (HDPE) liners within Pond 1 and Pond 2, a new emergency backup generator adjacent to the existing blower building, and new blowers inside of the existing blower building; replacing the existing aeration piping and diffusers, and existing effluent pumps; and completing improvements to the emergency overflow.
Access to the work areas would be from an unpaved private road off the paved public Alameda Avenue. Temporary staging of construction equipment and materials would occur within City-owned property at the Shastina WWTP. No physical improvements are required to establish the staging area.

Notice of Exemption
Exempt Status
Categorical Exemption
Type, Section or Code
Class 1, §15301 (Existing Facilities); Class 3, §15303 (New Construction or Conversion of Small Structures)
Reasons for Exemption
Class 1 covers the operation, repair, maintenance, 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. Class 3 covers the construction and location of limited numbers of new, small facilities or structures, and the installation of small new equipment and facilities in small structures.
The project is consistent with the categorical exemptions noted above because work would consist of completing minor alterations to existing facilities, replacing existing equipment, installing new equipment within an existing structure, and installing a generator. Improvements would not involve expansion of existing use at the Shastina WWTP.
As documented in the NOE, the proposed project would not have a significant effect on the environment due to unusual circumstances; would not result in damage to scenic resources within a Scenic Highway; is not located on a hazardous waste site pursuant to §65962.5 of the Government Code; would not cause a substantial adverse change in the significance of a historical resource; and would not result in cumulative impacts.
