Report to City Council
Meeting Date: February 19, 2025
Title: SACOG Presentation on the 2025 Blueprint Project 5 Background: Background on SACOG:

The Sacramento Area Council of Governments is where local government leaders across the region come together to advance the goals of economic prosperity, connected communities, and vibrant places. SACOG works with the six counties and 22 cities in the region to solve challenges that are too big for any one jurisdiction to solve on its own. SACOG plays a central role in transportation infrastructure planning and funding assistance for cities, counties, transit operators, and other entities responsible for providing for the mobility needs of the region's residents. One of SACOG's main roles as the state and federally recognized Metropolitan Planning Organization for the region, is to maintain the region's long-range, fiscally constrained, transportation plan and accompanying land use strategy. This plan must be updated every four years in coordination with local government agencies and demonstrate how the region is working to advance local, regional, state, and federal policy priorities. SACOG is currently undergoing an update of this plan, titled Blueprint, and anticipates adoption of the plan in 2025.

Background on Blueprint:

The 2025 Blueprint will outline recommendations for public land use policy and transportation investment strategies for the Sacramento region for the next 30 years. This plan will lay out a set of strategies for an integrated, multimodal transportation system and a regional land use development pattern that can create a more thriving region that works for all residents. The plan aims to connect housing to jobs, education, goods and services, and recreational opportunities while protecting and enhancing our region's natural and working landscapes.

Aside from this plan being a federal and state requirement, SACOG will use the 2025 Blueprint update to help local agencies coordinate and prioritize efforts to attract greater investment in the region through grants, private investment, and economic growth while protecting our region's natural environment, existing economies, and improving quality of life for all residents.

At the Live Oak City Council meeting, Clint Holtzen, from SACOG, will provide a short presentation and answer any council questions on the 2025 Blueprint. The presentation will outline the findings from the outreach process and the land use analysis. It will also provide an overview of the opportunities SACOG is offering for public and stakeholder involvement in the Environmental Impact Report and Draft Plan. Additionally, the presentation will provide a summary of the various programs SACOG has available or is developing to assist public agencies in implementing the region's vision for the future.

Report to City Council
Meeting Date: February 19, 2025
Title: Well 2 PFAS Update
Contact Information: Jeff Nelson, interim Public Works Director Location: Well 2
Background: The State of California had groundwater samples collected from the City's 5 water supply wells on 8 August 19, 2024 and had the samples tested for Polyfluoroalkyl Substances (PFAS). One of the four PFAS chemicals tested for, PFHxS, was detected in Well 2 at a concentration of 3.3 nanograms/liter or parts per trillion (ppt); above the State's adopted Notification Level of 3 ppt, but below the State's adopted Response Level of 20 ppt. Staff reported these results to City Council during the November 20, 2024 Regular City Council meeting. As this concentration was below the Response Level of 20 ppt, the State required no further action be taken regarding this detection of PFHxS.
41 Analysis: While not required by the State, Staff resampled Wells 1, 2 and 4 on December 5, 2024. PFHxS was detected at a concentration of 3.4 ppt in the sample collected from Well 2, similar to the results from the sample collected from this well in August, 2024. Again, 3.4 ppt of PFHxS is below the State's Response Level of 20 ppt.

Please also note that water from Well 2 is blended/mixed with water from Well 1 at the Booster Pump Station (BPS) where it is then pumped into the City's water supply system. A blended water sample was collected directly from the BPS; PFHxS was detected at a concentration of 2.5 ppt in this sample, below the Notification Level of 3.0 ppt.

Staff will continue to monitor the City's wells for the presence of PFAS. Staff are also working on identifying the potential sources of PFAS in the City's wells. Staff will keep the City Council informed of these activities with periodic reports at future City Council meetings.

The laboratory reports from the December 5, 2024 sampling event, as well as some fact sheets and other relevant information are included as an appendix to this staff report. Additional information regarding PFAS can be found at the following web sites:

NARRATIVE
Lab Order: Z120354
Project ID: 7130-LIVE OAK WELL|5110001
General Qualifiers and Notes
Caltest authorizes this report to be reproduced only in its entirety. Results are specific to the sample(s) as submitted and only to the parameter(s) reported.

Caltest certifies that test results meet California Environmental Laboratory Accreditation Program (CA-ELAP) and/or National Environmental Laboratory Accreditation Program (NELAP) requirements, as applicable, unless stated otherwise.

All analyses performed by EPA Methods or Standard Methods.

Dilution Factors (DF) reported greater than '1' have been used to adjust the result, Reporting Limit (RL), and Method Detection Limit (MDL).

All Solid, sludge, and/or biosolids data is reported in Wet Weight, unless otherwise specified.

Analyses performed at Caltest for pH, Dissolved Oxygen, and Chlorine Residual, as well as laboratory filtrations for Dissolved Metals (excluding Mercury) are not performed within the 15 minute holding time as specified by 40CFR 136.3 table II.

Results Qualifiers: Report fields may contain codes and non-numeric data correlating to one or more of the following definitions:

ND - indicates analytical result has not been detected at or above the Reporting Limit (RL), or at above the Method Detection Limit (MDL) when it is included on the report and is not otherwise noted.

RL - Reporting Limit is the quantitation limit at which the laboratory is able to detect an analyte. An analyte not detected at or above the RL is reported as ND unless otherwise noted or qualified. For analyses pertaining to the State Implementation Plan of the California Toxics Rule, the Caltest Reporting Limit (RL) is equivalent to the Minimum Level (ML). A standard is always run at or below the ML. Where Reporting Limits are elevated due to dilution, the ML calibration criteria has been met.

MDL - The Method Detection Limit is defined as the minimum measured concentration of a substance that can be reported with 99% confidence that the measured concentration is distinguishable from method blank results.

J - reflects estimated analytical result value detected below the Reporting Limit (RL) and above the Method Detection Limit (MDL).

The 'J' flag is equivalent to the DNQ Estimated Concentration flag.

B - indicates the analyte has been detected in the blank associated with the sample.

SS - compound is a Surrogate Spike used per laboratory quality assurance manual.

NOTE: This document represents a complete Analytical Report for the samples referenced herein and should be retained as a permanent record thereof.
