Your Water Sources
The City of Vallejo owns and operates two permitted public water systems for the benefit of our customers in two major service areas.

The City of Vallejo Water System and service area provides drinking water to customers within the city limits, to some customers in the unincorporated areas adjacent to City boundaries and to a limited number of customers in the City of American Canyon.

The City of Vallejo Water System customers are fortunate Lake Berryessa, transported to our facilities by the Put ah South
Canal. The City also receives surface water from the State Water Project. This water, from Lake Oroville, travels through the Sacramento River to the State’s North Bay Aqueduct pumping facilities. Our source water
pumping and distribution
facilities enable us to treat and
deliver
water from either one
of these sources or to blend
these sources before
treatment at the
Fleming Hill Water
Treatment Plant and
distribution to the
Vallejo service area.

The City of Vallejo
Lakes System and
service area is a
public water
system with its
own treatment
plant and distri-
bution system
that delivers
drinking water to
customers residing in the Green Valley, Old
Cordelia, Jameson
Canyon, Suisun Valley, Willotta Oaks and Gordon Valley areas.

This system and service area also has water available from two distinct surface water sources. In addition to the Solano Project’s Lake Berryessa water delivered from the Putah South Canal by agreement with the Solano Irrigation District, this system treats water from Lakes Frey and Madigan, which are two interconnect- ed lakes owned by the City of Vallejo. T
he Green Valley Water
Treatment Plant can either treat these two sources separately or blend these two sources before treatment and delivery to our customers. In case of emergencies, portions of this system can receive treated water from the City of Fairfield. For a copy of their Annual Water Quality Report, please call (707) 437-5386. • Inorganic Contaminants, such as salts and metals, which can
be naturally occurring or result from urban storm water runoff, industrial or domestic wastewater discharges, oil and gas pro- duction, mining or farming;
• Pesticides and Herbicides, that may come from a variety of sources such as agriculture, urban storm water runoff and res- idential uses;
• Organic Chemical Contaminants, including synthetic and volatile organic chemicals, which are by-products of industri- al processes and
petroleum production, and can also come
from gas stations, urban storm water runoff, agricultural appli- cations and septic systems; and
• Radioactive Contaminants, that can be naturally occurring or be the result of oil and gas production and mining activities.

Drinking water, including bottled water, may reasonably be expect- ed to contain at least small amounts of some cont
aminants. The
presence of contaminants does not necessarily indicate that water poses a health risk. More information about contaminants and potential health effects can be obtained by calling the USEPA's Safe Drinking Water Hotline at 1-800-426-4791.

Your Water Treatment Process
TheCity of Vallejowater system and service area receives its fin- ished water from the forty-two million gallons per day Fleming Hill Water Treatment Plant. This conventional treatment facility utilizes a multi-barrier process to ensure compliance with all State and Federal drinking water regulations and standards.

Initially, ozone is added to help remove dissolved organic matter and to aid in downstream processes. The water then flows to mixing
basins where coagulants are added and the water is gently agitated so that fine suspended particles come together to form large ‘floc’ particles that settle out of the water. This process, known as coagu- lation, flocculation and sedimentation is followed by the addition of more ozone to disinfect and remove unwanted color, taste and odor.

The next step is filtration, where the water flowsthrough multimedia
filters consisting of granular activated carbon and sand in order to meet strict standards for clarity and to reduce the levels of microbial contaminants that could be in the untreated source water. Following filtration, the water receives additions of causticsoda, for pH and alkalinity control; fluoride, for the prevention of dental caries; and finally, chlorine to provide microbial protection throughout Vallejo’ s
distribution system. Quality control and assurance is maintained at all times through uniform adherence to standard operating proce- dures and a meticulous schedule of laboratory analyses.

TheCity of Vallejo Lakes System’sGreen Valley Water Treatment Plant, which provides water service to the Lakes service area, can treat up to one million gallons a day.

First, the MI
EX™ pretreatment process removes naturally occurring
dissolved organic matter. This treatment, using ion exchange resin, enables us to meet the Disinfectant/Disinfection By-products Rule by sufficiently lowering the levels of total organic carbon, therefore limiting the formationof disinfection by-products such as total tri- halomethanes. Total trihalomethanes are chemicals formed over time in the distribution system when dissolved organic matter com- bineswith
chlorine. Regulations require we use chlorine to disinfect surface water.

The treatment plant’s conventional treatment process uses polymer to promote coagulation, flocculation and sedimentation that remove the majority of soil particles from the water. Then, the water gravity flows through multimedia filters consisting of anthracite and sand so thatit
will meet clarity standards required to decrease microbial con- taminants and to aid the disinfection process. Depending on which City of Vallejo AnnualWater Quality ReportWater Testing Performed in 2019 continued on outside panel
water source or blend of sources we are treating (Lakes Madigan and Frey and/or Putah South Canal), we may add soda ash in order to increase alkalinity and pH. The last step of the treatment process adds chlorine to disinfect the water supply and to provide continual protection in the distribution system. This treatment plant does not add fluoride to your water.

A Message From the United States
Environmental Protection Agency
The sources of drinking water (both tap water and bottled water) include rivers, lakes, streams, ponds, reservoirs, springs and wells.

As water travels over the surface of the land or through the ground, it dissolves naturally occurring minerals and, in some cases, radioac- tivematerial, and can pick up substances resulting from the pres- ence of animals or from human activity.

Contaminants thatmay
be present in source water include:
• Microbial Contaminants, such as viruses and bacteria, which may come from sewage treatment plants, septic systems, agricultural livestock operations and wildlife;

The City of Vallejo welcomes this yearly opportunity to provide our customers with the Annual Water Quality
Report.We have included information so you know where your drinking water comes from, how it is treated and how its quality com- pares to drinking water standards.

The tables in this report show each constituent found, the level at which they occur, how their level compares with standards and their most likely source. For more information about this report,or for
any questions relating to your drinking water,please call Danielle Public Participation
You are invited to participate in our public forum and voice your opinions and concerns about your drinking water. The Vallejo City Council meets on various Tuesdays, throughout the year, at 7:00 p.m. at 555 Santa Clara Street, Vallejo. You may call the City Clerk at (707) 648-4527 for specific meeting dates.

Bonham, City of Vallejo, Water Quality Manager, at (7
07) 649-3473.

In order to ensure that tap water is safe to drink, the U.S.

Environmental Protection Agency (USEPA) and the State Water Resources Control Board (State Board) prescribe regulations that limit the amount of certain contaminants in water provided by public water systems. State Board regulations also establish limits for contaminants in bottled water that must provide the same protection for public health.

This report contains information from water quality testing in 2019 and shows how your water compares with primary and secondary standards established by the State Water Resources Control Board and the U.S. Environmental Protection Agency (USEPA). Primary standards are health related standards whereas secondary standards relate to consumer acceptance of the water supply and govern qualities such as taste, odor and color.

The highest level of a contaminant that is allowed
in drinking water. Primary MCLs are set as close
to the PHGs (or MCLGs) as is economically and
technologically feasible. Secondary MCLs are set
to protect the odor, taste and appearance of
drinking water
.

MCLG-Maximum Contaminant Level Goal:

The level of a contaminant in drinking water
below which there is no known or expected risk
to health. MCLGs are set by the U.S. EPA.

Primary Drinking Water Standards:

MCLs for contaminants that affect
health along
with their monitoring and
reporting requirements, and water treatment
requirements.

Secondary Drinking Water Standards:

MCLs for aesthetic characteristics of water (such
as color, taste, and odor) that may affect the
consumer’s acceptance of their water supply.

COPPER (ppb at the 90th %) 1.3
15 PRIMARY STANDARDS—LEAD and COPPER STUDY—Monitoring of Customers’ Tap Water Every three years the City is required to sample at the customers' faucets for lead and copper. This monitoring ensures our water is not too corrosive and does not leach unsafe levels of these metals into your drinking water. Compliance measurements are from the 90th percentile (the highest level measured from 90% of the homes sampled). The latest monitoring, for both water systems, did not detect lead from 90% of the homes sampled.

If present, elevated levels of lead can cause serious health problems, especially for pregnant women and young children. Lead in drinking water is primarily from materials and components associated with service lines and home plumbing. The City of Vallejo is responsible for providing high quality drinking water, but cannot control the variety of materials used in plumbing components.

When your water has been sitting for several hours, you can minimize the potential for lead exposure by flushing your tap for 30 seconds to 2 minutes before using water for drinking or cooking. If you are concerned about lead in your drinking water, you may wish to have your water tested. Information on lead in drinking water, testing methods, and steps you can take to minimize exposure is available from the Safe Drinking Water Hotline or at http://www.epa.gov/safewater/lead.

USEPA Unregulated Chemical Monitoring Requirements
Throughout 2018, the USEPA required all large public water systems to monitor for additional chemicals, not yet regulated. The purpose of this monitoring identifies the occurrence and levels of these chemicals in the public water supply. The USEPA uses this information to determine whether these chemicals need to be assessed for health effects and future regulations. This table shows the chemicals found and the levels at which they occur. This monitoring program pertains only to the City of Vallejo Service area.

Vulnerability Assessments Table
Special Health Concerns
Some people may be more vulnerable to contaminants in drinking water than the general population. Immunocompromised persons such as persons with cancer undergoing chemotherapy, persons who have undergone organ transplants, people with HIV/AIDS or other immune system disorders, some elderly, and infants can be particularly at risk from infections. These people should seek advice about drinking water from their health care providers. The USEPA/Centers for Disease Control (CDC)
guidelines on appropri-
ate means to lessen the risk of infection by Cryptosporidium and other microbial contaminants are available from the Safe Drinking Water Hotline at 1-800-426-4791.

Source Water Assessments and Vulnerability Summaries
Source Water Assessments evaluate the quality of the water used as a drinking water supply for local communities and examine the water’s vulnerability to possible contamination from activities within the watershed. Source Water Assessments were completed in 2012 for the Putah South Canal and in 2016 for Lakes Frey and Madigan. The North Bay Aqueduct’s (Sacramento Delta) assessment was completed in 2016. The adjacent table summarizes the vulnerability of each water source and provides a contact name if you would like copies of the complete assessments.

Message from Environmental Protection Agency continued from inside Your Water Treatment Process
The City of Vallejo water system and service area receives its fin- ished water from the forty-two million gallons per day Fleming Hill Water Treatment Plant. This conventional treatment facility utilizes a multi-barrier process to ensure compliance with all State and Federal drinking water regulations and standards.

Initially, ozone is added to help remove dissolved organic matter and to aid in downstream processes. The water then
flows to mixing
basins where coagulants are added and the water is gently agitated so that fine suspended particles come together to form large ‘floc’ particles that settle out of the water. This process, known as coagu- lation, flocculation and sedimentation is followed by the addition of more ozone to disinfect and remove unwanted color, taste and odor.

The next step is filtration, where the water flows
through multimedia
filters consisting of granular activated carbon and sand in order to meet strict standards for clarity and to reduce the levels of microbial contaminants that could be in the untreated source water. Following filtration, the water receives additions of caustic soda, for pH and alkalinity control; fluoride, for the prevention of dental caries; and finally, chlorine to provide microbial protection throughout V allejo’s
distribution system. Quality control and assurance is maintained at all times through uniform adherence to standard operating proce- dures and a meticulous schedule of laboratory analyses.

The City of Vallejo Lakes System’sGreen Valley Water Treatment Plant, which provides water service to the Lakes service area, can treat up to one million gallons a day.

First, the M
IEX™ pretreatment process removes naturally occurring
dissolved organic matter. This treatment, using ion exchange resin, enables us to meet the Disinfectants and Disinfection Byproducts Rule by sufficiently lowering the levels of total organic carbon, therefore limiting the formation of disinfection byproducts such as total tri- halomethanes. Total trihalomethanes are chemicals formed over time in the distribution system when dissolved organic matter com- bines with chlorine. Regulations require that we use chlorine to disinfect surface water.

The treatment plant’s
conventional treatment process uses polymer
to promote coagulation, flocculation and sedimentation which removes a majority of the soil particles from the water. Then, the water gravity flows through multimedia filters consisting of anthracite and sand so that it will meet clarity standards required to decrease microbial con- taminants and to aid the disinfection process. Depending on which City of Vallejo AnnualWater Quality Report Water Testing Performed in 2020 continued on outside panel
water source or blend of sources we are treating (Lakes Madigan and Frey and/or Putah South Canal), we may add soda ash in order to increase alkalinity and pH. The last step of the treatment process adds chlorine to disinfect the water supply and to provide continual protection in the distribution system. The Green Valley Water Treatment Plant does not add fluoride to your water.

Vulnerability Assessments Table
Special Health Concerns
Some people may be more vulnerable to contaminants in drinking water than the general population. Immunocompromised persons such as persons with cancer undergoing chemotherapy, persons who have undergone organ transplants, people with HIV/AIDS or other immune system disorders, some elderly, and infants can be particularly at risk from infections. These people should seek advice about drinking water from their health care providers. The USEPA/Centers for Disease Control (CDC)
guidelines on appropri-
ate means to lessen the risk of infection by Cryptosporidium and other microbial contaminants are available from the Safe Drinking Water Hotline at 1-800-426-4791.

Source Water Assessments and Vulnerability Summaries
Source Water Assessments evaluate the quality of the water used as a drinking water supply for local communities and examine the water’s vulnerability to possible contamination from activities within the watershed. Source Water Assessments were completed in 201 7 for the Putah South Canal and in 2016 for Lakes Frey and Madigan. The North Bay Aqueduct’s (Sacramento Delta) assessment was completed in 2016. The adjacent table summarizes the vulnerability of each water source and provides a contact name if you would like copies of the complete assessments.

Environmental Protection Agency (USEPA) and the State Water Resources Control Board (State Water Board) prescribe regula- tions that limit the amount of certain contaminants in water provided by public water systems. State Water Board regula- tions also establish limits for contaminants in bottled water that provide the same protection for public health.

This report contains information from water quality testing in 2021 and shows how your water compares with primary and secondary standards established by the State Water Resources Control Board and the U.S. Environmental Protection Agency (USEPA).

This Consumer Confidence Report (CCR) reflects changes in drinking water regulatory requirements during 2021. These revisions add the requirements of the federal Revised Total Coliform Rule (rTCR), effective April 1, 2016, to the existing state Total Coliform Rule (TCR).

The revised rule maintains the purpose to protect public health by ensuring the integrity of the drinking water distribution system and monitoring for the presence of microbials (i.e., total coliform and E. coli bacteria). The USEPA anticipates greater public health protection as the rule requires water systems that are vulnerable to microbial contamination to identify and fix problems. Water systems that exceed a specified frequency of total coliform occurrences are required to conduct an assessment to determine if any sanitary defects exist. If found, these must be corrected by the water system.

The state Revised Total Coliform Rule became effective July 1, 2021.

be naturally-occurring or result from urban storm water runoff, industrial or domestic wastewater discharges, oil and gas pro- duction, mining or farming;
• Pesticides and Herbicides, that may come from a variety of sources such as agriculture, urban stormwater runoff and res- idential uses;
• Organic Chemical Contaminants, including synthetic and volatile organic chemicals, which are byproducts of industrial processes and petroleum production, which may also come from gas stations, urban stormwater runoff, agricultural applications and septic systems; and
• Radioactive Contaminants which may be naturally-occurring or the result of oil and gas production and mining activities.

Drinking water, including bottled water, may reasonably be expect-
ed to contain at least small amounts of some contaminants. The presence of contaminants does not necessarily indicate that water poses a health risk. More information about contaminants and potential h ealth effects can be obtained by calling the USEPA's Safe Drinking Water Hotline at 1-800-426-4791.

Initially, ozone is added to help remove dissolved organic matter and to aid in downstream processes. The water then flowsto
mixing
basins where coagulants are added and the water is gently agitated so that fine suspended particles come together to form large ‘floc’ particles that settle out of the water. This process, known as coagu- lation, flocculation and sedimentation is followed by the addition of more ozone to disinfect and remove unwanted color, taste and odor.

The next step is filtration, where the water flowsthrough multimedia
filters consisting of granular activated carbon and sand in order to meet strict standards for clarity and to reduce the levels of microbial contaminants that could be in the untreated source water. Following filtration,the water receives additions of caustic soda (for pH and alkalinity control), fluoride (for the prevention of dental caries), and finally chlorine ( to provide microbial protection throughout Vallejo’s
distribution system). Quality control and assurance is maintained at all times through uniform adherence to standard operating proce- dures and a meticulous schedule of laboratory analyses.

TheCity of Vallejo Lakes System’sGreen Valley Water Treatment Plant, which provides water service to the Lakes service area, can treat up to one million gallons a day.

First, the MI
EX™ pretreatment process removes naturally-occurring
dissolved organic matter. This treatment, using ion exchange resin, enables us tomeet the Disinfectants and Disinfection Byproducts Rule by sufficiently lowering the levels of total organic carbon, therefore limiting the formation of disinfection byproducts such as total tri- halomethanes. Total trihalomethanes are chemicals formed over time in the distribution system when dissolved organic matter com- bines with chlorine.Regulations require that we use chlorine to disinfect surface water.

The treatment plant’s conventionaltreatment
process uses polymer
to promote coagulation, flocculation and sedimentation which removes a majority of the soil particles from the water. Then, the water gravity flows through multimedia filters consisting of anthracite and sand so that it will meet clarity standards required to decrease microbial con- taminants and to aid the disinfection process. Depending on which City of Vallejo AnnualWater Quality ReportWater Testing Performed in 2021 continued on outside panel
water source or blend of sources we are treating (Lakes Madigan and Frey and/or Putah South Canal), we may add soda ash in order to increase alkalinity and pH. The last step of the treatment process adds chlorine to disinfect the water supply and to provide continual protection in the distribution system. The Green Valley Water Treatment Plant does not add fluoride to your water.

15 PRIMARY STANDARDS—LEAD and COPPER STUDY—Monitoring of Customers’ Tap Water Every three years the City is required to sample at the homeowners' faucets for lead and copper. This monitoring ensures our water is not too corrosive and does not leach unsafe levels of these metals into your drinking water. Compliance measurements are from the 90th percentile (the highest level measured from 90% of the homes sampled). The latest monitoring, for both water systems, did not detect lead in 90% of the homes sampled.

If present, elevated levels of lead can cause serious health problems, especially for pregnant women and children. Lead in drinking water is primarily from materials and components associated with service lines and home plumbing. The City of Vallejo is responsible for providing high quality drinking water, but cannot control the variety of materials used in plumbing components.

When your water has been sitting for several hours, you can minimize the potential for lead exposure by flushing your tap for 30 seconds to 2 minutes before using water for drinking or cooking. If you are concerned about lead in your water, you may wish to have your water tested. Information on lead in drinking water, testing methods, and steps you can take to minimize exposure is available from the Safe Drinking Water Hotline at 1-800-426-4791 or at http://www.epa.gov/safewater/lead.

USEPA Unregulated Contaminant Monitoring Rule
Throughout 2018, the USEPA required all large public water systems to monitor for contaminants that are currently unregulated. Unregulated contaminant monitoring helps the USEPA and the State Water Resources Control Board to determine where certain contaminants occur and whether the contaminants need to be regulated. This monitoring program only applies to the City of Vallejo service area. The table below lists unregulated contaminants that were detected, as well as the range and average of those detections.

Vulnerability Assessments Table
Special Health Concerns
Some people may be more vulnerable to contaminants in drinking water than the general population. Immuno-compromised persons such as persons with cancer undergoing chemotherapy, persons who have undergone organ transplants, people with HIV/AIDS or other immune system disorders, some elderly, and infants can be particularly at risk from infections. These people should seek advice about drinking wat er from their health care providers. The USEPA/Centers for Disease Control (CDC)
guidelines on appropri-
ate means to lessen the risk of infection by Cryptosporidium and other microbial contaminants are available from the Safe Drinking Water Hotline at 1-800-426-4791.

Source Water Assessments and Vulnerability Summaries
Source Water Assessments evaluate the quality of the water used as a drinking water supply for local communities and examine the water’s vulnerability to possible contamination from activities within the watershed. Source Water Assessments were completed in 201 7 for the Putah South Canal and in 2016 for Lakes Frey and Madigan. The North Bay Aqueduct’s (Sacramento Delta) assessment was completed in 2016. The adjacent table summarizes the vulnerability of each water source and provides a contact name if you would like copies of the complete assessments.

Suggested Guidelines for Preparation of
Required Reports on PUBLIC HEALTH GOALS (PHGs)
to satisfy requirements of California Health and Safety Code Section 116470(b)
Background
Public water syst
ems serving more than 10,000 service connections must prepare a brief, written report in plain language by July 1, 2019 that gives information on the “detection” of any contaminants above the Public Health Goals (PHGs) published by the state’s Office of Environmental Health Hazard Assessment (OEHHA). The report must also list the “detection” of any contaminant above the Maximum Contaminant Level Goals (MCLGs) set by United States Environmental Protection Agency (U.S. EPA) for all other contaminants until such time as OEHHA has published PHGs for those contaminants.

It is emphasized that
the report only needs to provide information on the number of contaminants that a water system has found at a level exceeding a PHG or a MCLG.

The purpose of the l
egislation requiring these reports was to provide consumers with information on levels of contaminants even below the enforceable mandatory Maximum Contaminant Levels (MCLs) so they would be aware of whatever risks might be posed by the presence of these contaminants at levels below the MCLs. Additionally, each water system must provide an estimate of the cost to reduce the contaminant(s) to the PHG (or MCLG if there is no PHG) regardless of how minimal the risk might be.

The following should be c
onsidered when preparing the mandated reports:

1. The U.S. EPA and the Ca
lifornia State Water Resources Control Board (SWRCB)
Division of Drinking Water (DDW) establish MCLs at very conservative levels to provide protection to consumers against all but very low to negligible risk. In other words, MCLs are the regulatory definition of what is “safe.” Adopted MCLs are still the criteria for being in compliance, not those proposed or possible in the future, and certainly not MCLGs or PHGs.

ATTACHMENT NO. 5

Page 46 of 80 ends

2. MCLGs and PHGs are often set at very low levels depending on the established health risk, and in the case of U.S. EPA, MCLGs are also set at zero for some contaminants. Determination of health risk at these low levels is theoretical based on risk assessments with multiple assumptions and mathematical extrapolations. Many contaminants are considered to be carcinogenic and U.S.

EPA’s policy is to set the applicable MCLGs at zero because they consider no amount of these contaminants to be without risk. It is understood by all that zero is an unattainable goal and cannot be measured by the practically available analytical methods. Note that by regulation, OEHHA cannot set a PHG at zero and must calculate a numerical level to address risk, even though it may be unattainable or impossible to measure.

3. PHGs and MCLGs are
not enforceable. The Best Available Technology (BAT) to reach such low levels has not been defined and may not realistically be available.

Accurate cost estimates are difficult, if not impossible, and are highly speculative and theoretical. Therefore, they have limited value and may not warrant significant investment of agency time and money.

These reports are uni
que to California. They are required in addition to the extensive public reporting of water quality information that California water utilities have been doing for many years and in addition to the federally mandated Consumer Confidence Reports (CCRs). Hence, it should be kept in mind that IN ADDITION to this required report, each utility will continue reporting ANNUALLY in great depth on the quality of the water it serves.

The guidance herei
n is intended to assist water suppliers in completing the required reports in a responsible manner without expending excessive amounts of resources that are better used to comply with the many regulatory mandates designed to ensure safe drinking water.

Guidance on prepari
ng these reports is needed because the legislative language does not spell out all of the detailed answers to questions that arise. Neither the DDW nor OEHHA have issued any guidelines regarding the report. In fact, while OEHHA has a mandate to determine and provide information on “numerical health risk,” they otherwise have no involvement or authority regarding the report.

The DDW is the primary
enforcing agency of all provisions of the Health and Safety (H&S) Code relative to drinking water systems. It has the authority to ensure that public water systems comply with the report requirement. DDW requests that utilities report in writing as to how they have complied with the fundamental requirements of this section, which are:
1) Prepare a brief w
ritten report,
2) Hold a public hearing (meeting), and

Page 47 of 80 ends

3) Notify DDW that the meeting was held and the report is available.

Detailed Guideline
s:

I. Who must prepare a P
HG report?
California H&S Code, Sec
tion 116470(b) is clear that a system ONLY needs to do a report IF it has at least 10,000 service connections AND IF it exceeds one or more PHGs or MCLGs. Also, a public hearing is NOT required if a report does not have to be prepared.

Utilities that do NO
T have to do the report may choose to submit an information item to their governing board advising them that no report is required.

This report is req
uired every three years.

II. Wholesalers (<
10,000 service connections) are NOT required to do a PHG report.

Wholesalers who d
o not directly serve more than 10,000 service connections are not required to meet the PHG report requirements of California H&S Code, Section 116470(b).

III. Timing, Notificat
ion, Meetings
A. Timing and Meeting:

The report must be prepared by July 1, 2019. A public
hearing, which can be held as part of any regularly scheduled meeting, should be held sometime after July 1 and prior to reporting to DDW. The public hearing “should be held within a reasonable time after the report’s completion” so the information is current. The purpose of the hearing is to “accept and respond to” public comment. The governing board or council of public water agencies would also likely approve the staff report at that time.

This would represent endorsement by the board of the part of the report where any action (or no action) would be proposed regarding reduction of contaminants to levels lower than required for compliance with MCLs.

B. Notification: The
re is no requirement to send a copy of the report to the public. Public agencies must “notice” public hearings so this hearing would be subject to the normal notice requirements (i.e., number of days advance, publishing in appropriate newspaper, etc.) The notice would appropriately indicate the report is the subject of the hearing and indicate it is available for the public to review or to get a copy upon request.

Page 48 of 80 ends

(NOTE: Investor-owned utilities will likely have to schedule a special “meeting” since they are not subject to the same meeting notice requirements and may not have any authority to hold a “public hearing” per se. Their notification of the public could however be similar to public agencies (e.g., publication of legal notice in newspaper of general circulation.)

C. Submission of Reports: DDW does not specifically require that a copy of the report be submitted to them.

IV. Interpretations

A. What contaminants must be covered?

A table of relevant current PHGs, MCLGs, MCLs, and Detection Limits for purposes of Reporting (DLRs) is attached to this guidance as Attachment No. 1.

1. Only contaminants that have an existing MCL AND were “detected” at a level that “exceeds” the PHG or, where there is no PHG, the Federal MCLG, need to be included in the report. (See guidance below on “detected” and “exceed”)

2. All contaminants that, as of December 31, 2018, have Primary Drinking Water Standards (PDWS) set by California AND have an equivalent PHG or a MCLG. This includes chemical, microbiological and radiological constituents. PDWS may be either MCLs or Treatment Techniques (TT).

For example, the Surface Water Treatment Rule (SWTR) is a TT for the following contaminants: Giardia lamblia, viruses, Cryptosporidium, Legionella and heterotrophic bacteria (HPC). A TT is set when it is not possible to reliably analyze for the contaminant of concern (the SWTR) or when it is not feasible or appropriate to set a numerical standard (e.g., the Lead & Copper Rule).

3. It does NOT include contaminants, such as radon, for which U.S. EPA has considered adopting an MCL, nor does it include any contaminants DDW plans to regulate in the future.

It does NOT include contaminants for which there is no final PHG or MCLG as of December 31, 2018, nor does it include any secondary MCLs (e.g., TDS, SO
4, Na, etc).

B. What data are to be used for the report due by July 1, 2019?

1. It is recommended that the data used should be from the 3 consecutive calendar years prior to the year the report is prepared. For example, the

Page 49 of 80 ends

2019 report would be based on the analytical data from samples taken in 2016, 2017, and 2018. The data should be the same as that used by the drinking water system in determining compliance with DDW requirements. In most cases, this would be after blending or treatment.

Individual well data would only be used if the well feeds directly to the distribution system.

2. For utilities that
purchase water from another agency or from a
wholesaler, it is suggested that the same guidance or ground rules be followed as for the CCRs. If the only source for a retail system is treated water from a wholesaler and that water contains a constituent above a PHG or MCLG, the retailer should use its own distribution system monitoring data. For systems with both its own sources of water and purchased water, the retailer should evaluate its own distribution system compliance monitoring and compare the annual average value with the PHG or MCLG.

C. What do the terms
“detect” and “exceed” mean in the context of the
required report?

1. Keep in mind that the
re are no regulations that relate to “meeting” or
“complying with” PHGs. The logical approach would be to use the same procedures and requirements that Title 22 of the California Code of Regulations specify for determining compliance with MCLs. For example, if Title 22 or DDW guidance specifies that the average of a group of samples be compared to the MCL for compliance purposes, the same averaging should be used to compare to the PHG or MCLG. For most constituents (coliform is an exception), compliance with MCLs is measured at the “point of entry” to the distribution system. This means that, for the most part, the analytical results for each well must be evaluated separately and compared to the MCLG or PHG. If wells are blended or treated before delivery to the system, the judgment as to whether there was a “detection exceeding the MCLG or PHG” should be based on the “point of entry” data just as for compliance with MCLs.

2. Be sure to report t
he PHG (or MCLG) as a number equal to or greater
than 1.0 as specified in the State Consumer Confidence Report Guidance for Water Suppliers. It is recommended that all data be converted to match CCR data. Attachment No. 1 concentration numbers are given as mg/L, unless otherwise noted.

3. Keep in mind that if
a utility determines that a constituent has been
found at a level exceeding the PHG or MCLG, a cost estimate is mandated. A utility would ordinarily be required to perform a cost

Page 50 of 80 ends

estimate only if it is clear that the MCL has been clearly exceeded, not just momentarily, or on one sample. In the same way, only when the PHG/MCLG level is clearly exceeded should a cost estimate be calculated and reported.

4. Significant figures, analytical detection limits, reporting limits, and different methods of determining compliance, all affect the assessment of which constituents were “detected” above the PHG or the MCLG.

5. Results that are reported below the state regulatory Detection Limit for Purposes of Reporting (DLR - See California Code of Regulations Title 22, Sections 64432 & 64445.1 and other DDW guidance on compliance reporting) should be treated as 0 (zero) which is accepted DDW practice.

U.S. EPA also recommends treating non-detection (ND) as zero.

6. As in all cases of reporting results to the state, the results of analyses should be rounded to reflect the appropriate number of significant figures. (EXAMPLE: For coliform bacteria, the MCLG is 0% samples positive per month which indicates one significant figure. So, if during 2013, a system had a positive sample but the percentage of samples positive for the month was <0.49%, this could be rounded to one significant figure, as the MCLG is expressed, so it would be rounded to 0%.) (SECOND EXAMPLE: For a constituent like PCBs where the MCL is 0.5 ppb and the DLR is 0.5 ppb, how do you determine if you exceeded the MCLG of “zero”? Webster defines “zero” as “having no measurable or otherwise determinable value,” which, in effect, is the DLR. So for PCBs, if the average of results for a given well is less than the DLR, the value would be reported as “zero.” Note that by regulation, OEHHA cannot set a PHG at zero and must calculate a numerical level to address risk.)

7. In averaging the results for a constituent over a specified period during which some of the data is less than the DLR, the average value obtained should be rounded to the appropriate significant figure before comparing to the PHG or MCLG. (EXAMPLE: If a well were sampled for PCE and 0.6 ppb was found and the resample showed 0.6 ppb, it would constitute a confirmed positive detection. But if 3 additional compliance samples were taken from the well and all had less than 0.5 ppb, which is the DLR, then averaging the 5 samples would give an average of 0.24 ppb, which would be rounded to zero. The average from the well does not exceed the PHG of 0.06 ppb, and no cost estimate would be needed for this well.)

D. What does the term “best available technology” (BAT) mean as used in this portion of the law?

1. While a specific definition of the term is not in the California H&S Code, the accepted meaning in all other sections is that it refers to a technology to achieve compliance with MCLs. In fact, where “best available technology” is listed or explained (Sections 64447, 64447.2 & 64447.4), the usage is “for achieving compliance with the MCLs.” This is also true for BAT specified in federal regulations.

2. However, in Section 116470(b)(4), the term refers to “BAT,” if any is available on a commercial basis, to remove or reduce the concentration of the contaminant. Specifically, subdivision (b)(5) requires cost estimates of using the technology described in subdivision (b)(4) to “reduce the contaminant...to a level at or below the” PHG (or MCLG).

3. Obviously, where MCLGs are set at zero, there may not be commercially available technology to reach a non-detectable level. This should be clearly stated in the report. Since there is little data readily available to “estimate” cost of treatment to achieve absolute zero levels, rough estimates of “BAT” as defined in law might be used with a clearly written caveat that use of this “BAT” may still not achieve the PHG or MCLG and the costs may be significantly higher to do so.

E. How should the report deal with coliform?

U.S. EPA has revised the 1989 Total Coliform Rule (TCR). The Revised Total Coliform Rule (RTCR) offers a meaningful opportunity for greater public health protection beyond the 1989 TCR. As of April 1, 2016, PWSs and primacy agencies must comply with the requirements of the RTCR. DDW is currently implementing the federal RTCR, alongside the existing state TCR. DDW plans to notice the draft regulations for public comment in summer 2019.

1. Keep in mind that the MCL is a monthly percent of positive samples (not to exceed five percent (5%)) and no actual numbers of coliform are determined or are required to be determined. The MCLG of zero (0) is therefore appropriately interpreted as zero percent of samples per month, NOT zero samples positive. (For example, if the system did not exceed 0.5% positive samples in any month, the system would not exceed the MCLG of 0 because anything less than 0.5% would be rounded down to 0, which is consistent with the significant figure of the MCLG.)

2. If it is determined that the system has exceeded the MCLG of zero percent for coliform bacteria, the following factors are pertinent to

Page 52 of 80 ends

deciding what action, if any, is appropriate to consider and to estimate costs for that action:
a. Exceeding zero perc
ent coliform bacteria in any month, in and of
itself, would not normally constitute the need for any treatment or action;
b. There is no ac
tion that could be taken with absolute certainty that
could ensure the system would always have zero-percent (0%) coliform every single month;
c. The “best availa
ble technology” (to meet the MCL, not the MCLG) is
specified by DDW in California Code of Regulations Title 22, Section 64447 and for the most part is already followed by many systems; d. The one single ac
tion that would most likely decrease the possibility
of positive coliform detection would be to significantly increase the disinfectant residual. This would likely result in increased disinfection byproducts (DBPs). While disinfection protects against acute health risks, such as E. coli and Giardia, DBPs can have potentially adverse chronic health risks. The limits to the amount of disinfectant residual allowed in the distribution system are the maximum residual disinfectant levels (MRDLs) as established by the Disinfectants and Disinfection Byproducts Rule (DBPR);
e. Utilities should po
int out the positive, proactive steps they take to
prevent coliform contamination in the distribution system, including preventive maintenance, main flushing, special monitoring, residual maintenance and testing, cross-connection control, etc.

F. How should the re
port deal with E. coli?
U.S. EPA has revised the
1989 TCR. The RTCR offers a meaningful opportunity for greater public health protection beyond the 1989 TCR. As of April 1, 2016, PWSs and primacy agencies must comply with the requirements of the RTCR, which includes an E. coli MCL. DDW is currently implementing the federal RTCR, alongside the existing state TCR. DDW plans to notice the draft regulations for public comment in summer 2019.

1. Keep in mind that the
E. coli MCL is based on either an E. coli positive
repeat sample following a total coliform (TC) positive routine sample or a TC-positive repeat sample following an E. coli -positive routine sample.

The PWS should report the number of E. coli detections that occurred during the three-year period (2016, 2017, and 2018 for this report). The

Page 53 of 80 ends

MCLG of zero is therefore appropriately interpreted as zero samples positive.

2. If it is determined that the system has exceeded the MCLG of zero for E. coli, the following factors are pertinent for deciding what action, if any, is appropriate to consider and for estimating costs:

a. Exceeding zero E. coli bacteria at any one time, in and of itself, would not normally constitute the need for any treatment or action.

b. There is no action that could be taken with absolute certainty that could ensure that the system would always have zero-percent E. coli every single time.

c. The “best available technology” (to meet the MCL, not the MCLG) that is specified for total coliform by DDW in California Code of Regulations Title 22, Section 64447 would also apply to E. coli and for the most part is already followed by many systems.

d. The one single action that would most likely decrease the possibility of positive E. coli detection would be to significantly increase the disinfectant residual. This would likely result in increased disinfection byproducts (DBPs). While disinfection protects against acute health risks, such as E. coli and Giardia, DBPs can have potentially adverse chronic health risks. The limits to the amount of disinfectant residual allowed in the distribution system are the maximum residual disinfectant levels (MRDLs) as established by the Disinfectants and Disinfection Byproducts Rule (DBPR).

e. Utilities should point out the positive, proactive steps they take to prevent E. coli contamination in the distribution system, including preventive maintenance, main flushing, special monitoring, residual maintenance and testing, cross-connection control, etc.

G. How should the report handle the MCLGs of zero for Giardia lamblia, Cryptosporidium, Legionella and viruses?

1. The MCL for pathogenic micro-organisms is a TT (i.e., the SWTR). No monitoring is mandated for the organisms because there are no standardized methods for testing or the analyses are not timely (like virus testing – 30 days) to provide public health protection.

2. For these reasons, since the intent of the TT (SWTR) is to protect against these pathogens, it can properly be assumed that if the SWTR is met, that

Page 54 of 80 ends

the utility has met the MCLG because there is no uniform way to assess possible pathogen levels.

3. For utilities doing v
oluntary monitoring of pathogens (such as Giardia and
Cryptosporidium), the results are appropriately considered research or for operational purposes and not for compliance purposes.

H. How should the re
port deal with Lead and Copper?

1. Any lead or copper v
alues below the respective DLR should be reported
as zero.

2. For monitoring lead a
t the tap, if the 90 percentile lead value is ND, or
<0.005 mg/l, then you should assume you do not exceed the lead PHG of

0.2 ppb.

3. For monitoring copper
at the tap, if the 90 percentile copper value is not
above 300 ppb, then you have not exceeded the copper PHG.

4. While not precis
ely stated in the regulations, best available technology for Lead and Copper compliance is a TT (in lieu of MCLs) of “optimized corrosion control.” For larger systems with >10,000 service connections, this depends on a series of steps involving sampling, reports, studies, etc.

If a system meets the requirements of having optimized corrosion control but still has a 90 percentile lead or copper value above the PHGs, it is not clear what additional steps could be considered, particularly without causing other potential water quality problems. It may be appropriate to explain this in a straight-forward manner rather than putting in “hypothetical” cost figures.

I. Must the repo
rt deal with Total Trihalomethanes (TTHMs) or Haloacetic Acids (HAAS)?
No. MCLG/PHG e
xceedances must be reported only for those contaminants that have a primary drinking water standard in place and an associated MCLG/PHG.

Although U.S. EPA has adopted MCLGs for some individual THMs and HAAs (such as dibromochloromethane or dichloroacetic acid), there are no MCLs in effect for these individual constituents. Likewise, U.S. EPA has adopted standards for the cumulative byproduct groups, but there are no MCLGs or PHGs established for the groups. In California, DDW has adopted an MCL for both cumulative byproduct groups, but there are no associated PHGs. (Note: OEHHA published a draft PHG of 0.8 ppb for total trihalomethanes in September 2010, but it had not been finalized as of December 31, 2018. On October 5, 2018, OEHHA publish proposed draft PHGs of 0.4 ppb for chloroform, 0.5 ppb for bromoform, 0.06 ppb

Page 55 of 80 ends

for bromodichoromethane, and 0.1 ppb for dibromochloromethane. The proposed PHGs were not adopted as of December 31, 2018.) However, indivi
dual MCLs and MCLGs for bromate and chlorite exist, so they must be included in the report if detected.

J. How should water u
tilities handle gross alpha and uranium?
When looking at th
e results of any radionuclide monitoring done in the 3-year period to be covered by the report, there are several things to keep in mind:

As indicated in C.1
of this Guidance, where averaging is done to determine
compliance with MCLs, it should also be done in considering PHGs. This is important for radionuclides because compliance is often based on averaging.

Unlike most other
constituents, laboratories doing radionuclides report some results that are LOWER than the state DLR. Title 22, 64442 (h)(3)(c) states: “If a sample result is LESS than the DLR in Table 64442, ZERO shall be used to calculate the annual average.......” Also, it says for Gross Alpha: “......1/2 of the DLR shall be used to calculate the annual average.”
Where Gross Alpha analy
ses are used in lieu of analyzing for uranium, Radium
226 or 228, the procedure outlined in Title 22, 64442(f) should be followed. (Note: The 95% confidence limit is often reported by labs as MDA95.) K. Do utilities have to
report detections of hexavalent chromium?
Water systems do
NOT have to report anything on hexavalent chromium
because there is no MCL. While there is an MCL and an MCLG for TOTAL chromium, systems will not have to report on it either since the MCLG (100 ppb) is much higher than the California MCL (50 ppb).

V. Disclosure of Num
erical Public Health Risk Associated with PHGs/MCLs and Identification of Category of Risk
H&S Code, Section 11
6470(b)(2) requires the report to disclose the numerical public health risk associated with both the maximum contaminant level and public health goal for each contaminant detected in drinking water that exceeds the public health goal, and Section 116470(b)(3) requires an identification of the category of risk to public health associated with exposure to the contaminant. In February 2019, OEHHA prepared and published an updated “Health Risk Information for Public Health Goal Exceedance Reports” document. It is included as Attachment No. 2, and can be accessed at https://oehha.ca.gov/media/downloads/proposition-65/public-health-goal- report/phgexceedancereport020719.pdf.

Page 56 of 80 ends

V. Cost Estimates
The most difficult a
spect of the required report is estimating the cost of treatment.

Agencies are urged to keep in mind that because of the advisory nature of the report, the non-enforceable aspect of PHGs and MCLGs, and the highly speculative applicability of technology to achieve “zero” levels, only very preliminary cost estimating is appropriate and necessary.

Remember that a c
ost estimate is only required for a constituent if you determine that it was “detected” above the PHG or MCLG. If the MCLG is zero and the result (after approximation, averaging, rounding) is less than the DLR, no cost estimate is needed. (Remember that many DLRs are LOWER than the PHG, so “detection” above the DLR does not necessarily mean that it is above the PHG.)
The cost estimate
s should not be low estimates because that would give a mistaken impression that achieving “zero” levels would have a lower price tag when the amount of uncertainty and unknowns would be very high. Given the uncertainties, it might be appropriate to consider reporting a range of costs.

For the 2019 gui
dance, ACWA is providing a revision of its previous treatment cost information.

Attachment No. 3
to this guidance includes several tables which provide "ranges" of costs for installing and operating several treatment technologies. These data have been gathered from a variety of sources and represent estimates for different size systems, different sources, and different constituents targeted for reduction by the treatment.

Table 1 represents
the results of a 2012 ACWA Survey of its member agencies. This has been revised using the average 2018 ENR Cost Index.

Table 2 includes dat
a from several agencies that was gathered separately from the 2012 ACWA survey. This has been revised using the average 2018 ENR Cost Index.

Table 3 is treatment c
ost data from previous ACWA Guidance documents with the costs updated to 2018. This has been revised using the average 2018 ENR Cost Index.

The law specifies th
at the report should only “estimate the aggregate cost and the cost per customer of utilizing the technology” to reduce the level down to the PHG. There is no specification of what is to be estimated: initial construction cost, annualized costs of construction and O&M, or another way of expressing cost. It is suggested that each utility may do it the way they report other costs. (EXAMPLES: 1. Initial Cost of Construction, including % increases for each of design, planning, CEQA, permitting, contingency, etc. =$10 million, or $1000 per customer, plus an ongoing O&M cost of $1

Page 57 of 80 ends

million, or $100 per customer, forever; 2. Annualized Cost of Construction plus O&M = $2 million, or $200 per customer.)
All possible tec
hnologies do not have to be evaluated for each constituent to compare costs. For example, if granular activated carbon (GAC) and reverse osmosis (RO) are both possible treatment technologies to try to lower the level of a particular contaminant to the “zero” PHG/MCLG level, it is appropriate to specify and estimate costs for the technology that would likely be used, keeping in mind there are significant uncertainties based on a variety of factors. If the utility has multiple contaminants to address in the report, one technology (i.e., RO) may address them all, so a cost estimate for RO only could suffice.

General “order of mag
nitude” estimates are adequate. It is assumed that ALL costs including capital, land, construction, engineering, planning, environmental, contingency and operations and maintenance (O&M) costs should be included but general assumptions can be made for most of these items.

If a system choose
s to do its own cost estimating rather than use the costs in Attachment No. 3, it is recommended that generally available cost estimating guides be used such as from U.S. EPA, WRF, AWWA, ASCE, or textbooks, manuals, journals.

The following is a list of excellent, relatively current references that might be used:
(1) Implementatio
n of Arsenic Treatment Systems, Part 1. Process Selection; AWWA Research Foundation and U.S.E.P.A, Published by AWWA RF and AWWA, 2002, (2) Implementatio

Cost Analysis of Arsenic Treatment in California, October, 2009, JAWRA, UC Davis, Hilkert, Young, Green and Darby.

U.S. EPA includes cos
t data in the Federal Register for each regulation when it is proposed or adopted. (NOTE: U.S. EPA estimates generally do not consider state- specific concerns and some costs have been known to be underestimated in the past so costs should be increased appropriately and based on utility experience.) The

Page 58 of 80 ends

experience of other utilities in your area that have installed treatment to meet MCLs or data reported in journals is valuable as well.

Utilities may also choo
se to have their engineering consultants prepare these very general cost estimates.

VI. Sample Hypotheti
cal Report
Attachment No. 4 is
a comparable attempt to show what a PHG-required report might look like for a "hypothetical" water system that serves more than 10,000 service connections and had one or more PHG/MCLG exceedances in the three-year period ending December 31, 2015, as an example. It is NOT the only way the report might be done. The sample is based on these guidelines. If there appears to be a conflict between the sample and the guidelines, the guidelines should be followed.

tions about these guidelines or any of the attachments, contact Adam Borchard at ACWA at 916-441-4545.

GLOSSARY OF WATER QUALITY TERMS

Best Available Technology (BAT): The best available treatment techniques or other means available for achieving compliance with MCL.

Health Risks: Health risks with respect to Public Health Goals are based on long term exposures to low levels of contaminants as would occur with drinking water, rather than high doses from a single or short term exposure. The health risk category describes the type of health risk. Types of health risks include chronic toxicity (shortened life span, thyroid effects, liver effects, or kidney effects), acute toxicity (gastrointestinal effects), carcinogenicity (cancer), and reproductive toxicity.

Maximum Contaminant Level (MCL): The highest level of a contaminant that is allowed in drinking water.

MCLs are set as close to PHGs as is economically and technologically feasible . Unless stated otherwise, the term MCL in this report refers to primary MCL.

Maximum Contaminant Level Goal (MCLG): The level of a contaminant in drinking water below which there is no observable adverse effect to human health. MCLGs are similar to California PHGs, but not equivalent.

MCLGs are nonenforceable goals established by the U.S. EPA based solely on health considerations for non carcinogenic co
nstituents. For all carcinogenic constituents (i.e. those chemicals known or suspected of causing cancer), U.S. EPA's policy is to set the MCLG at zero.

Numeric Health Risk: Describes the cancer risk. At the California MCL no cancer risk is calculated from chemicals considered "noncarcinogens." For carcinogens, PHGs are set at a concentration that does not pose any significant risk of cancer; this is usually a oneinonemillion excess cancer risk ( 1 x106).

One-in-one-million Risk Level: At the "oneinonemillion " risk level, no t more than one person in a population of one million people drinking the water daily for 70 years would be expected to develop cancer as a result of exposure to that chemical in the water.

Parts per billion (ppb): The weight of a chemical dissolved in a volume of water. Equivalent to micrograms per liter (ug/L).

Parts per million (ppm): The weight of a chemical dissolved in a volume of water. Equivalent to milligrams per liter (mg/L).

Public Health Goal (PHG): The concentration of a contaminant in drinking water below which no known or anticipated adverse health effects will occur with an adequate margin of safety. This level is based on estimates that would pose a significant risk to individuals, including the most sensitive subpopulations, consuming water every day over an entire lifetime. PHGs are unique to California and are established by the Office of Environmental Health Hazard Assessment (OEHHA), a subdivision of the California Environmental Protection Agency.

ACTION ITEM 9.B.

DATE: November 15, 2022
TO: Mayor and Members of the City Council
FROM: Christina Ratcliffe, Planning and Development Services Director Steve Arnold, Chief Building Official
SUBJECT: HOLD A PUBLIC HEARING ON THE PROPOSED ORDINANCE, ADOPTING BY REFERENCE, PURSUANT TO GOVERNMENT CODE SECTION 50022.2 AND CALIFORNIA CODE OF REGULATIONS TITLE 24, THE 2022 BUILDING STANDARDS CODE PARTS 1 THROUGH 12, AND THE 2021 INTERNATIONAL PROPERTY

MAINTENANCE CODE, AND ADOPTING LOCAL ADMINISTRATIVE AMENDMENTS

THERETO AND FINDING THE ORDINANCE EXEMPT FROM THE CALIFORNIA

ENVIRONMENTAL QUALITY ACT (CEQA) PURSUANT TO CEQA GUIDELINES SECTION 15061(B)(3)

RECOMMENDATION
Hold a public hearing on the proposed ordinance adopting by reference, pursuant to Government Code section 50022.2 and California Code of Regulations Title 24, the 2022 Building Standards Code Parts 1 through 12, and the 2021 International Property Maintenance Code, and adopting local administrative amendments thereto and finding the ordinance exempt from the California Environmental Quality Act (CEQA) pursuant to CEQA Guidelines section 15061(b)(3).

REASONS FOR RECOMMENDATION
The State Legislature requires local governments to adopt the most recent editions of the model codes related to building standards, rules and regulations, along with any local amendments. On January 1, 2023, the 2022 California Building Standards Code, also known as the California Code of Regulations (CCR) Title 24, will go into effect. These regulations are applicable to all structures in all cities and counties in California. In addition, adoption of the International Property and Maintenance Code will provide useful provisions related to vacant buildings, such as board up standards and maintenance of the exterior premises on private property.

BACKGROUND AND DISCUSSION
Every three years, the State Building Codes are updated and disseminated by the State. The current code is the 2019 Code, which went into effect January 1, 2020. The 2022 California Building Standards Code (California Code of Regulations Title 24), adopted and approved by the California Building Standards Commission, includes Parts 1 through 12 as follows:

Part 1 California Administrative Code
Part 2 California Building Code (Volumes 1 and 2) Part 2.5 California Residential Building Code
Part 3 California Electrical Code
Part 4 California Mechanical Code
Part 5 California Plumbing Code
Part 6 California Energy Code
Part 7 (Vacant - Not Applicable)
Part 8 California Historical Building Code Part 9 California Fire Code

Date: November 15, 2022
Subject: HOLD A PUBLIC HEARING ON THE PROPOSED ORDINANCE, ADOPTING BY REFERENCE, PURSUANT TO GOVERNMENT CODE SECTION 50022.2 AND CALIFORNIA CODE OF REGULATIONS TITLE 24, THE 2022 BUILDING STANDARDS CODE PARTS 1 THROUGH 12, AND THE 2021 INTERNATIONAL

PROPERTY MAINTENANCE CODE, AND ADOPTING LOCAL ADMINISTRATIVE

AMENDMENTS THERETO AND FINDING THE ORDINANCE EXEMPT FROM THE

CALIFORNIA ENVIRONMENTAL QUALITY ACT (CEQA) PURSUANT TO CEQA GUIDELINES SECTION 15061(B)(3)

Page 2 ends

Part 10 California Existing Building Code
Part 11 California Green Building Code
Part 12 California Reference Standards Code

The International Property Maintenance Code was updated in 2021 and is not part of the Code unless specifically adopted. In addition, the minimal local administrative amendments to the Code must be readopted.

A summary of the code changes is attached.

After introduction of the ordinance at the October 25, 2022 Council meeting, staff completed the public notice requirements and is returning tonight for the public hearing and second reading of the ordinance. Once adopted, the 2022 California Building Standards Codes and the 2021 International Property Maintenance Code and local administrative amendments will become effective January 1, 2023.

Public Outreach
City staff posted the 2022 Title 24 California Code Changes Summary and FAQs sheets regarding the new 2022 California Building Standards Code, 2021 International Property Maintenance Code, and local amendments on the Building Division's web page, along with a link to the new Code. Notices have been placed at the permit center and the Vallejo Weekly Newsletter will inform the community of the upcoming change. In addition, staff will continue to conduct outreach to contractors and developers informing them of these changes. Last, the 2022 edition of the California Building Standards Codes, as well as the 2021 International Property Maintenance Code and the local amendments, are available for review at the Planning and Development Services Counter during counter hours, 9 AM-3 PM Monday through Thursday, excluding holidays, or by appointment.

FISCAL IMPACT
The cost of implementation, education and enforcement associated with the new regulations is estimated at $25,000 and is funded through the current Building Division budget. This includes staff training to implement the new code, public outreach, information handouts, the purchase of Code Books, and online code subscriptions and other costs necessitated by the adoption of new codes.

ENVIRONMENTAL REVIEW
Adoption of this Ordinance is exempt from the California Environmental Quality Act (CEQA) in accordance with section 15061(b)(3) of the CEQA Guidelines because such action is largely administrative in nature, is designed to improve rather than degrade the environment, and it can be seen with certainty that it will not have a significant effect on the environment.

1 INTRODUCTION
During the 2021 Triennial Code Adoption Cycle, California state agencies reviewed the most recent edition of national model codes and standards, and made amendments and additions to most parts of the California Building Standards Code, Title 24 of the California Code of Regulations (Title 24). This publication contains information regarding substantive changes of interest to code users as they familiarize themselves with the 2022 edition of Title 24. For ease of reading, this document uses all normal font style (no italics). When looking at Title 24, it is a good idea to learn about and understand the various margin markings, banners and text styles that will indicate where changes have been made to the code and what amendments are model code changes versus California amendments. An explanation of margin markings can be found in the preface of each part of Title 24.

State agency acronyms that may be used in this publication BSC – Building Standards Commission
CDPH – California Department of Public Health
CEC – California Energy Commission
DSA – Division of the State Architect
DWR – Department of Water Resources
HCD – Department of Housing and Community Development
OSHPD – Office of Statewide Health Planning and Development (now Department of Health Care Access and Information – HCAI)
SFM – State Fire Marshal
For the applications of amendments adopted by the various state agencies, reference Chapter 1 of each part of Title 24.

The parts of Title 24 may be abbreviated as follows:

CBC – California Building Code, Part 2, Volumes 1 and 2 CRC – California Residential Code, Part 2.5
CMC – California Mechanical Code, Part 4
CPC – California Plumbing Code, Part 5
CFC – California Fire Code, Part 9
CEBC – California Existing Building Code, Part 10
CALGreen – California Green Building Standards Code, Part 11 CRSC – California Referenced Standards Code, Part 12
To avoid confusion with other acronyms, abbreviations are not used for the California Administrative Code (Part 1), California Electrical Code (Part 3) or California Energy Code (Part 6).
2 Note that there were no significant updates to the California Historical Building Code, Part 8 of Title 24, and Part 7 is vacant, so those parts are not listed here. There are no changes to Part 8 because the State Historical Building Safety Board adopted the 2022 California Historical Building Code by carrying forward existing provisions from the 2019 edition without further amendment.

Model code developers:

Every three years the national model codes and standards are published, and by law California is required to incorporate specific model codes and standards into Title 24.

The model code publishers often issue significant code change documents explaining national code updates and the reasons for them. Links to those documents are provide below.

3 CALIFORNIA ADMINISTRATIVE CODE – PART 1
Chapter 1 – Building Standards Commission
1-209 Code Advisory Committees
Amended existing section footnote to clarify the requirements of the Fire Official and Local Government Water Efficiency Official positions in the Code Advisory Committees.

Sections 1-407, 1-411, 1-415, 1-419
Added document accessibility as a requirement for documents included in state agencies’ rulemaking submittals and added reference to Government Code Section 11546.7.(a).
1-507 Fee Collection
Amended existing section to remove information regarding the check-only payment method, added instructions for submitting payment and forms by mail (check) or email (electronic payment platform), and let fee payers know that they may only use the approved electronic payment platform, and that there is information regarding the platform on CBSC’s website.

Chapter 3 – State Fire Marshal
Article 3-1 General Provisions and Article 3-2 Definitions Added sections to Chapter 3 that was reserved for SFM in the 2019 edition. These sections provide clarifying language regarding the SFM fire and life safety authority for state-owned buildings, specified state-occupied buildings, and state institutions.

Chapter 4 – Division of the State Architect
4-309(c).2.B Reconstruction or alteration projects in excess of $100,000 in cost
Repealed exception to the section as it is inconsistent with the definition of “rehabilitation” in the regulations. The exception also implied that only the “…elements of the lateral force resisting system” need be evaluated, which led to confusion as DSA’s Seismic Performance Requirements per Table 317.5 explicitly require that the evaluation include assessment of non-structural components. 4-330 Time of beginning construction and partial construction Changed requirements that construction must commence on all school buildings with an approved project within four years instead of one year or else the approval is void.

Given this new four-year rule, extensions no longer apply and were repealed. Added an exception permitting DSA to withdraw approval or institute post-approval 4 requirements as necessary to address life-safety concerns in response to information received after approval of plans and before commencement of construction. 4-335(f)4 Structural tests and special inspections
Clarified requirements to provide DSA with daily special inspection reports when requested.

Group 3, Article 3 and deletion of Article 4
Revised procedure regarding submission of landscape plans for modifications, rehabilitations and new construction of landscape areas at public K-12 schools and community colleges.

The revisions include the elimination of a fee for review of landscape plans and revisions to the self-certification form, a provision that periodic site observations during construction will occur to ensure the work is completed in accordance with CALGreen Section 5.304 requirements, and replacement of two previously required self- certification forms with a single form.

Chapter 7 – Office of Statewide Health Planning and Development 7-111 Definitions
Added clarification that the equipment referred to in the definition of “Actual Construction Cost” is construction equipment only.

Added the definition of “Start of Construction” to clarify that the start date of construction may include actual physical work as well as the preparation for construction such as manufacturing components offsite.

Sections 7-111, 7-121, 7-130, 7-133 and others
Combined “Phased Plan Review” and “Collaborative Review and Construction” into a single process called “Integrated Review.” Renamed “Phased Plan Review” to “Integrated Review” so the definition of “Integrated Review” is added, the definition of “Phased Plan Review” is repealed, all references to “Phased Plan Review” and “Collaborative Review and Construction” are removed, and Memorandum of Understanding (MOU) is renamed to Integrated Review Plan (IRP).

Sections 7-113, 7-153 and others
Amended existing language to provide requirements for electronic submittals and field records.
7-123 Preliminary plans and specifications
Amended existing language to remove “outline” from the submittal requirements for specifications during a preliminary review as it has been proven an outline specification is insufficient for most preliminary reviews. 5 7-129 Time limitations
Amended following subsections:
7-129(b) to provide revised time limitations based on the cost of a project. 7-129(d) to include a description of when a project is considered abandoned. 7-129(d) Exception to limit the exception to paragraphs (a) and (b) so they do not apply to managed projects. Manage project time limitations would not apply as the durations are negotiated.
7-133 Fees
Amended following subsections:
7-133(a) to allow for projects with estimated construction cost of less than $250,000 to be invoiced at the rate of 2.0 percent of the estimated construction cost. 7-133(h) to remove collaborative review and replace phased review with integrated review. The fee of 1.95% is to be applied to integrated review. 7-145 Continuous inspection of the work
Clarified the requirement for the Inspector of Record to notify the office in writing when work is started and for the field record report to include the time and date of all correspondence with the contractor regarding incomplete work, potential deficiencies or deviation which require the contractor’s attention. Added additional requirements for the reports.

6 CALIFORNIA BUILDING CODE – PART 2
Tall Wood/Mass Timber provisions in various chapters of Part 2 BSC—DSA—HCD—OSHPD—SFM
Sections regarding construction elements of Tall Wood/Mass Timber and Heavy Timber were early adopted by various state agencies as amendments to the 2019 California Building Code (CBC) during the 2019 Intervening Code Adoption Cycle and issued as a supplement with a July 1, 2021, effective date. The amendments are repealed, as they are now included in the adopted 2021 International Building Code (IBC).

Building Standards Commission
105.5.1 [Permit] Expiration
New section changed permit expiration from 180 days to 12 months. Includes a provision stipulating that every permit shall remain valid if the work on the site authorized by the permit is commenced within 12 months after its issuance. This amendment also allows for permit extensions; the exception being when the work authorized by the permit is determined to have been abandoned. The new code language reflects statutory requirements in Assembly Bill 2913 (Statutes of 2018), which became operative January 1, 2019, and amended Health and Safety Code (HSC) Section 18938.5(b)(2)(B) and added HSC Section 18938.6 to Building Standards Law.

CBSC Information Bulletin 19-03
regarding permit expiration dates was issued May
23, 2019, to local building departments, state agencies and CBSC interested parties. 7 Office of Statewide Health Planning and Development

1.10.2 OSHPD 2, 2A and 2B
OSHPD added new occupancy classifications to address distinctions between skilled nursing facility and intermediate care facility buildings erected with specific construction materials.

OSHPD 2 has been split into two (2) categories. OSHPD 2A is for skilled nursing facility and intermediate care facility buildings of single-story, wood-frame, or light steel frame construction or buildings of single-story, wood-frame, or light steel frame construction where only skilled nursing or intermediate care services are provided if the building is separated from a building housing other patients of the health facility receiving higher levels of care and must meet model code requirements.

OSHPD 2B skilled nursing facility and intermediate care facility buildings of all other types must meet the requirements designated by the OSHPD 2B banner.

If the only designation is OSHPD 2, the application is for both 2A and 2B.

State Fire Marshal

1.11.1 Specified state-occupied buildings
New definition with 11 criteria has been added in response to Senate Bill 85 (Public resources: omnibus trailer bill. (2019-2020)) that required the State Fire Marshal to provide a more accurate definition.

1.11.6 Certificate of Occupancy
Amendment citing a reference to Section 105.2 clarifying work exempt from permit.

Division of the State Architect, Department of Housing and Community Development, Office of Statewide Health Planning and Development, and State Fire Marshal
110.3.12 Types IV-A, IV-B and IV-C connection protection inspection This amendment was added in the 2019 intervening cycle but is now part of model code language in the 2021 IBC, therefore, this section is repealed to avoid duplication.

Chapter 2 – Definitions
California Energy Commission
CLIMATE ZONE Amended definition with specific reference to Figure 100.1-1 of the California Energy Code pertaining to the applicability of assigned climatic criteria for geographic regions to distinguish between the International Energy Conservation Code (IECC) and the California Energy Code.
8 State Fire Marshal

TODDLER New defined term to align with the legal definition of toddlers from Health and Safety Code Section 1596.55. By distinguishing age differences, officials will be able to classify the related occupancies based on social services’ classifications used for licensing.

Chapter 3 – Occupancy Classification and Use
State Fire Marshal
304.1 Business Group B and 304.4 Higher education laboratories Removed new model code language about higher education laboratories from Section 304.1 and deleted new model code Section 304.4 since model code language for higher education laboratories is not used in California and conflicts with California’s Group L occupancy classification.
305.2 Group E, Child care facilities
Amendments clarifying child care regarding emergency situations applying to Groups I, E and R Occupancies.
310.3 Residential Group R-2
Amended the definition for Group R-2 to meet requirements of SB 234 (Chapter 244, Statutes of 2019): Small and large family child care in apartment houses can operate in R-2 occupancies when they comply with the regulations and with Health and Safety Code Section 1597.46.

Among other requirements, the amendment revises Section 508.2.4 Exception and limits permitted, unseparated accessory covered entrances to those required by Section 11B-206.4.10 for weather protection at entrances to medical care and long-term care facilities or Section 1224.33.2.1, emergency medical service exterior entrances. The amendment eliminates a conflict with provisions enforced by Centers for Medicare-Medicaid Services (CMS).

Table 508.4 Required separation of occupancies (hours), Footnote J Amendment to the footnotes in Table 508.4 that reduces the fire-resistive separation criteria for covered vehicle entrances required by other provisions of the California Building Code associated with Group I-2 occupancies from 2-hour to 1- hour fire-resistance-rated construction.

Chapter 7A – Materials and Construction Methods
State Fire Marshal
Extensive amendments to Chapter 7A Wildland-Urban Interface (WUI) regulations.

The amendments were developed through the Office of the State Fire Marshal WUI task group and collaboration with local fire departments, other state agencies, building industry, testing labs, and stakeholders.

Modified to properly reference the California Energy Code. 1202.3.1 California Energy Code and International Energy Conservation Code (IECC) Climate Zones and Table 1202.3.1 IECC vs California Energy Code Climate Zone Comparison
Added section and table to prevent confusion between climate zones identified in ICC model codes and climate zones identified in the California Energy Code by explaining the relationship between the two codes and adding Table 1202.3.1 to represent these differences.

Department of Housing and Community Development
1202.2.1 Ventilated attics and rafter spaces and 1202.3 Unvented attic and unvented enclosed rafter assemblies

Table 1202.3 Insulation for condensation control
Repealed reference to specific climate zones from the table since the California Energy Commission adopted a new Table 1202.3.1 from the International Energy Conservation Code.

Office of Statewide Health Planning and Development
1224.3 Definitions
HANDWASHING STATION Amended existing language to clarify that hands-free operation is required at the door and not at the handwashing fixture.

INVASIVE PROCEDURE New definition to be used to determine the classification of the imaging room or procedure room required.

LOCATION TERMINOLOGY Terms for relationship to an area or room. 12 READILY ACCESSIBLE Amended existing language to avoid ambiguity by removing the requirement that the area or room also be “directly accessible.” New language added to include option for locating readily accessible areas or rooms to within 200 feet of department or space served to accommodate space orientation or security concerns.

PROCEDURE ROOM New definition specifically designates the procedure room as the intermediate level room for procedures that do not require a full surgical environment.

RESTRICTED AREA Amended existing language to better align with Facilities Guidelines Institute (FGI), which stipulates that a restricted area is a designated space contained within the semi-restricted area and accessible only through a semi- restricted area. This definition is required to determine the level of procedure room to be used and the requirements therein.

SEMI-RESTRICTED AREA New defined term per request of CDPH. This area applies to intermediate level procedures and imaging as well as peripheral areas that support surgical services.

START OF CONSTRUCTION OSHPD added the definition to Part 1, California Administrative Code. The banner note added to this definition avoids ambiguity and clarifies that the term is not adopted by OSHPD.

UNRESTRICTED AREA New defined term per CDPH request. This area applies to any area of the department that is not defined as semi-restricted or restricted. This definition is required to determine the level of control outside a surgical area or within a medical department.
1224.4.4.1 Examination, treatment, and procedure rooms
Amended existing language to add “procedure room” to the heading. 1224.4.4.1.2 Treatment room
OSHPD has coordinated with CDPH to add a requirement for providing a new service space for exercise stress testing. This space can be in several locations within a hospital and not assigned to any one service. Amended language allows for exercise stress testing in a treatment room due to the need for space for a crash cart and possible resuscitation.
1224.4.4.1.4 Procedure room
Added new language to align with
Facilities Guidelines Institute (FGI) requirements
and renumbered following sections.
1224.4.4.4.1 Medication preparation room
Per CDPH request, amended existing language to remove the requirement that a medication preparation room be directly accessible from the nursing station. 13 Table 1224.4.6.1
Line 6 has been identified specifically for “Intensive Care” to avoid confusion with the similarly named room on Line 3.

Table 1224.4.6.5
Added Note 1 to the line for Patient Toilet Room under column 1226. Current language is confusing and is often misinterpreted that a nurse call station is required in all clinic patient toilets under column 1226. The note clarifies that a nurse call station is not required for Primary Care, Chronic Dialysis or Psychology Clinic patient toilet rooms.
1224.4.11 and 1224.4.11.4.1 Interior Finishes
Added a pointer to the new table for different levels of procedure and imaging rooms. Includes new Table 1224.4.11.4a which identifies the different levels of exam/procedure rooms as well as the different classes of imaging rooms, including the room type, the uses in each type of room, if the room is unrestricted, semi- restricted or restricted, how it is accessed, and the level of finishes required. 1224.14.2 Support areas

1 EXHIBIT A
2022 California Building Standards Code

FACTUAL FINDINGS ESTABLISHING THE REASONABLE NEED FOR LOCAL

AMENDMENTS TO PORTIONS OF THE BUILDING STANDARDS CODE BASED

UPON CLIMATIC, TOPOGRAPHICAL, GEOLOGICAL, OR ADMINISTRATIVE

PROVISION
Health and Safety Code sections 17922, 17958, 17958.5, and 17958.7 permit the City to amend the 2022 California Building Standards Code as reasonably necessary because of local climatic, geological, and topographical conditions.

Section 1 of this Exhibit sets forth various findings that apply to Vallejo, explaining the administrative provisions and the local conditions that necessitate the various changes.

Section 2 of this Exhibit explains which findings apply to which amendments.

In numerous instances herein, the City has opted to make findings even though it is not legally required to do so. For example, if a change to a building standard is administrative in nature, then no finding is legally required. Likewise, if an amendment does not contradict a building standard, but merely supplements the standard, then the City need not make a finding.

Section 1. General Findings.

The following findings apply in the City of Vallejo and explain why the changes to the California Building Standards Code are reasonably necessary because of climatic, geologic, or topographical conditions or local administrative regulations in the City.

A. Climatic, Geological, and Topographical Conditions
The City of Vallejo has 18.9 miles of shoreline. At any given time, there are an estimated 500 vessels moored within 10-200 feet of the Vallejo shoreline. Portions of the shoreline, especially near vessel mooring sites, are occupied by buildings, particularly those with wood-framed structures or sidings, as well as piers and pilings that are combustible.

Highly combustible dry grass, weeds and brush are common in the areas adjacent to built-up locations at or near the shoreline six to eight months of each year. The arrangement and location of natural and human-made surface features, including hills, slopes, housing developments, commercial developments, fire stations, streets, and roads, combine to limit feasible response routes for fire resources. Fires moving through steep terrain double for every 20 percent of slope increase. Erratic terrain and erratic winds can cause fires to grow in an unpredictable manner.
2 Precipitation ranges from 15 to 24 inches per year with an average of 20.39 inches per year. Ninety percent falls during the months of October through March and 10 percent from April through September. Typically, 0.8 percent of rainfall occurs during the fire season. This is a dry period of at least six months. Additionally, the area is subject to recurrent drought. The climatic region is currently in a drought phase that has lasted nine years. Additional droughts can be expected locally in the future.

Temperatures have been recorded as high as 111 degrees Fahrenheit. Average summer highs are in the 90-degree range. Prevailing winds in the area are from the south or southwest in the mornings and from the north or northwest in the afternoons. However, winds are experienced from virtually every direction at one time or another. Velocities are generally in the 14 miles per hour (MPH) to 23 MPH range, gusting from 25 to 35 MPH. Forty MPH winds are experienced occasionally and winds up to 55 MPH have been registered locally. During the winter half of the year, strong, dry, gusty winds from the north move through the area for several days, creating extremely dry, hazardous fire conditions.

Local climatic, geologic, and topographic conditions impact fire prevention efforts, and the frequency, spread, acceleration, intensity, and size of fires which involve buildings in this community. Therefore, it is found to be reasonably necessary that the 2022 California Fire Code be changed or modified to mitigate the effects of the risks associated with the above conditions and allow access to all vessels moored, tied, anchored or otherwise to the shoreline of the City.

B. Administrative Regulations.

Local regulations necessary to carry out the application of the California Building Standards Code that do not establish standards may be enacted without meeting the requirements of sections 18941.5, 17958, 17958.5 and 17958.7 of the Health and Safety Code. Through the recommendation of the City Attorney, such amendments made to the California Building Standards Code are hereby found to be either administrative or procedural in nature which do not impact the technical standards within the Code or concern themselves with subjects which are not covered in the Code. The changes made include provisions making the Code compatible with other ordinances enforced by the City.

C. Not Applicable (N/A).

No findings need to be made because the code section at issue does not amend any building standard.
3 Section 2. Which Findings Apply to Which Amendments.

Amendments to the 2022 Edition of the California Building Standards Code are found reasonably necessary based on the condition cited within this Ordinance and Section 1 above or for an administrative process as follows.

Adopt a resolution authorizing the City Manager to execute the attached Consultant and Professional Services Agreement (Agreement) with West Yost & Associates, Inc. (West Yost), to provide consulting services for the Mare Island Infrastructure Assessment (MIIA) project.

REASONS FOR RECOMMENDATION
Executing the Agreement with West Yost allows the City of Vallejo to implement the work under the U.S.

Department of Commerce Economic Development Administration grant, which commits to completing an infrastructure assessment on Mare Island. West Yost will conduct a condition assessment of the island-wide infrastructure, including roads, sanitary sewer, storm water, and dry utilities to produce a final MIIA technical report. This information will help assist in future development of the island.

BACKGROUND AND DISCUSSION

Mare Island has a myriad of infrastructure that has been installed on the island over the course of many years.

The Navy did not have to comply with any regulatory permitting, so infrastructure was installed, expanded, and abandoned without much documentation. The Mare Island Infrastructure Assessment (MIIA) project will create one location for the status of the existing infrastructure facilities to help inform future development of the island.

The City submitted a grant application in the amount of $960,000 to the United States Department of Commerce Economic Development Administration (EDA) on October 30, 2020 under the Economic Adjustment Assistance Grant Program (Program) for the infrastructure assessment project. City staff had identified this grant funding as a viable source to assist the City’s efforts to study the overall infrastructure on Mare Island. Assessing the existing conditions of the infrastructure on the island will help attract future investment by providing the information necessary to assess future potential development infrastructure needs. The City's goals align very well with the EDA’s grant objectives, which are to support strategic investments for economic development, foster job creation, and attract private investment in economically distressed areas of the United Sates. The City received notification from the EDA on September 7, 2021, that it had been awarded the grant funding in the amount of $960,000.

On November 2, 2021, the City Council authorized acceptance of the grant. On June 17, 2022, the City issued a Request for Proposals (RFP) inviting qualified firms that could carry out the MIIA project to submit a
