Document Description
Notice of Exemption for the Irish Beach Water District Well Activation & Tank Restoration Project. The overall project objective is to improve drought and water storage resiliency and preparedness for the 50-year-old rural community of Irish Beach, through its Water District, even in the face of potential reduced stream flows and decreasing annual rainfall. This will be accomplished by:
(1) Installation of a conventional 11,000-gallon “bolted steel on concrete foundation” water tank. A temporary poly tank is currently used to replace a failed original 10,000-gallon ferro-cement and redwood tank. Installation of a new bolted steel tank will be used to store the water from an existing well and serve as a buffer to match pumping capacity to system water use during times when stream water is unavailable.
(2) Equip and connect an existing proven well to the Water District system (power & watermain). Testing has shown this well will also require treatment (ozonation) for iron and manganese content. This additional well will increase available water supplies by approximately 13 acre-feet per year (AFY) and provide the necessary supplemental water when the stream diversion is unavailable. Associated improvements include installation of a 50± square foot equipment shed, PG&E connection, trenching and underground wire/piping connection within an existing easement.
(3) Replace the containment roof on an existing (c1973) 60,000 gallon in-ground gunite water tank with an engineered metal roof. The wooden roof on this tank reached the end of its useful life in 2020 and was removed. The loss of this tank could not have come at a more inopportune time. In the project, this is where the water from the Task 2 well will be treated, stored, and enter the Irish Beach Water District system.

Notice of Exemption
Exempt Status
Categorical Exemption
Type, Section or Code
15301, 15302, 15303 & 15304
Reasons for Exemption
The Project includes several components, all of which can be found to be Categorically Exempt from CEQA. The new 11,000-gallon tank will replace a previously existing 10,000-gallon tank and is Categorically Exempt pursuant to section 15302(c) which allows for the replacement or reconstruction of existing utility systems and/or facilities involving negligible or no expansion of capacity. Installation of a new tank will be used to store the water from an existing well and serve as a buffer to match pumping capacity to system water use during times when stream water is unavailable. It will not expand overall capacity of the water district rather it will make the district more resilient in times of drought. The proposed connection to the existing well will include PG&E power as well as trenching and underground wire/piping connection within an existing easement. These activities are Categorically Exempt pursuant to section 15301(a) and 15303(d) which allow for both the addition of electrical conveyances and water main extensions. CEQA Guidelines section 15304(f) also provides for minor trenching and backfilling where the surface is restored. The proposed replacement of the containment roof over an existing water tank is Categorically Exempt pursuant to section 15302(b) which allows the replacement of a commercial structure with a new structure of substantially the same size, purpose, and capacity. All activities proposed under the Project are replacement and/or additional utility connection within an existing Water District which does not alter their service area and/or capacity, but rather provides resiliency during times of drought.
