TUD PROJECTS

Addendum 1 – Algerine Slum Dam Project
Initial Study and Mitigated Negative Declaration (ISMND) Ditch Maintenance Activities

Project Overview:
The Tuolumne Utilities District prepared a master initial study/mitigated negative declaration for system-wide ditch maintenance activities certified by the TUD Board of Directors on September 12, 2017 hereby incorporated by reference as follows and available online at
https://tudwater.com/wp-content/uploads/2017/12/Final-Ditch-Maintenance-IS-MND-9-12-17-1.pdf

Algerine Slum Dam Project:
The Tuolumne Utilities District (TUD) receives raw water from the South Fork of the Stanislaus River via the PG&E Main Tuolumne Canal at points near Twain Harte and Phoenix Lake in Tuolumne County near Sonora California. The District operates about 70 miles of open ditch system delivering water from the Main Tuolumne Canal to 11 active water treatment plants spread throughout the TUD service area serving treated water to roughly 31,000 people and raw water to over 600 customers. One of these raw water conveyance structures is TUD’s Algerine Ditch that serves water to livestock ranches in the Wards Ferry ‐ Algerine Area. A slum dam diverts water from Curtis Creek into the Algerine Ditch and a small, private diversion (west bank), at a point located approximately 1,000 feet north of Old Wards Ferry Road. Water diverted by the Algerine ditch is first delivered to Curtis Creek upstream of this location via TUD’s Phoenix Ditch. The slum dam is a gold rush era structure that spans Curtis Creek, approximately 50 feet, and only functions to divert water; no water is impounded. The construction of the diversion is comprised of stacked rocks secured with mortar with a shotcrete overlay on most of the downstream and upstream dam facing surfaces.

Sonora Regional Wastewater Treatment Facility Improvements Project – Draft CEQA ISMND

Project Overview:
The proposed Sonora Regional Wastewater Treatment Facility Improvements Project will provide replacement of existing polishing ponds with a new activated sludge treatment facility consisting of the following: headworks primary screening and grit removal, new activated sludge/extended aeration secondary treatment processing, new secondary clarifiers, new chlorine disinfection facilities, renovated sludge digestion to aerated digestion, and new sludge dewatering facilities. A new administration and electrical building (Building A) will be constructed adjacent to the treatment facility. A new Building B will contain headworks and sludge dewatering systems. The existing digestion building will be a renovated Building C. Existing septage receiving station, headworks, primary clarifiers, trickling filters, and secondary clarifiers will be demolished as part of the project. The existing Emergency Storage Basin Pond A will be lined and reused in the proposed Project. The new facilities will be constructed in the location of the existing polishing ponds. The land area will be reclaimed by draining and filling the ponds with approximately 90,000 cubic yards of fill material to be generated onsite. Construction activities will include grading, site preparation, excavation, concrete placement, and mechanical and electrical equipment installation. The proposed Project construction is anticipated to take place in 2021 and 2022.

CEQA Process:

The District is seeking public comments on the environmental document for the proposed Project from local and state agencies, and interested organizations/persons. Written comments are preferred. The Initial Study/ Mitigated Negative Declaration (ISMND) discloses that, with the incorporation of mitigation, no significant environmental impacts are anticipated with the proposed Project. Comments received will be duly considered by the District prior to adoption of the document. The ISMND for the Project is available for review at the Tuolumne Utilities District office located at 18885 Nugget Boulevard, Sonora, CA 95370 and the Tuolumne County Clerk Office at 2 S. Green Street, Second Floor, Sonora, CA 95370.

Matelot Pipeline and Turbidity Station Project – Draft Initial Study and Mitigated Negative Declaration

Project Overview:
Tuolumne Utilities District (TUD) proposes the Matelot Pipeline and Turbidity Station Project (project), which includes constructing an 18-inch diameter raw water main up to 1,650 feet in length that would convey water from Matelot Reservoir in the north to the Columbia Water Treatment Plant (Columbia WTP) in the south. The project site consists of a 30-foot utility easement around the proposed pipeline alignment and the site of the proposed turbidity station. While the utility easement would be 30 feet in width, it is anticipated that all construction disturbance for the project would be contained within a 20-foot corridor along the pipeline alignment and an area of approximately 150 square feet at the turbidity station.

CEQA Process:
