Item No: D1
Prepared by: Kuna Muthusamy, P.E., Director Meeting Date: May 9, 2023 Approved by: John Conley, City Manager Agenda Location: Discussion SUBJECT: PESTICIDES AND CHEMICALS USED IN CITY PARKS AND STREETS RECOMMENDATION: Present and discuss pesticides and chemicals used in the City parks and streets.

CORRELATION TO CITY COUNCIL GOALS: (1) Climate and Environmental Responsibility; and (2) Parks & Recreation.

PRIOR ACTION: On August 9, 2022, City Council directed staff to work on an Integrated Pest Management (IPM) proposal specific to Vista, including costs and staff time (Vote: 5-0).

STATEMENT ON THE SUBJECT: On August 9, 2022, City Council discussed concerns regarding pesticides and herbicides used for eradication of weeds throughout the City. As a result, City Council directed staff to present and discuss the current use of pesticides and chemicals for weed eradication and the potential modified future use of such substances that incorporates Integrated Pest Management (IPM) principles.

Current Approach. The City currently implements a weed eradication program that targets the following locations:
• Major streets (along the shoulders and medians)
• State Route 78 freeway shoulder and ramps
• Parks, fire hazard open areas
• Wastewater easement areas
Overall, the City utilizes a tiered approach when performing eradication, with the least harmful option preferred. The first option is to remove weeds through physical or mechanical means. If this method is ineffective, inefficient, and costly, staff then uses chemical control or a combination of the two. The focus is to minimize the use of pesticides/chemicals, keeping the environment in mind.

For parks and the downtown (Vista Village) areas, the City's current weed control approach relies primarily on physical or mechanical removal. Chemical pesticides are occasionally used in these areas. Because high-speed traffic makes it unsafe for City staff and contractors to use physical or mechanical weed removal along major streets and State Route 78 shoulders and ramps, chemical methods are typically employed for these areas. The current chemical pesticides used are dithiopyr, a pre -emergent herbicide used to prevent weed growth, and glyphosate, a post -emergent herbicide used to kill weeds after they have started growing.

ACTION: Discussed pesticides and chemicals used in the City parks and streets and provided direction to staff to remove glyphosate and dithiopyr at parks, historic downtown, streets by schools, and to post when spraying pesticides. Vote: 4-0 (Green absent) ClerklSehretary

MEETING DATE: May 9, 2023 PAGE 2

SUBJECT: PESTICIDES AND CHEMICALS USED IN CITY PARKS AND STREETS Proposed Approach. Based on City Council direction, staff proposes a program that would eliminate, reduce, or substitute the use of current pesticides/herbicides for weed eradication as much as possible, focusing on areas where people are likely to be present. The chemical pesticides/herbicides the City currently uses (dithiopyr and glyphosate) would be effectively eliminated (limited to use only in infrequent emergencies) in high-foot traffic areas and areas where vulnerable populations, such as young children are likely to be present, including parks, along streets and medians adjacent to schools, and the Historic Downtown/Vista Village areas of the City. The primary approach to weed control in these areas would be mechanical control (hand removal), supplemented by use of natural or organic pesticides/herbicides when mechanical control is not effective. These are new products that the City does not currently use. Switching to use of these natural or organic pesticides would require purchasing new products and associated application equipment. Staff will also require training on application frequency and amounts and safety protocols for the use of these products. The City would retain the option to use the chemical pesticides currently being used only in rare, emergency situations, which would also require pre-approval and sign- off by a supervisor before use of those chemical pesticides.

Chemical pesticides would continue to be used for controlling weeds along major roads and State Route 78 areas. Pedestrian traffic is relatively limited in these areas. The chemical pesticide with the lowest EPA toxicity rating (danger, caution, or warning) will be used first, and pesticides with a higher toxicity rating will only be used if pesticides with a lower toxicity rating have proven ineffective. The typical application method is spraying from a vehicle. Switching to mechanical weed control (hand removal) would pose serious safety risk to City staff or contractors and dramatically increase labor hours and cost needed to achieve the same level of weed control. Caltrans uses similar chemical pesticides as the City and currently plan to continue its use to control weeds in Caltrans-maintained areas along State Route 78.

A draft IPM Program document that explains the proposed approach in more detail has been prepared and is included as Exhibit 1 for the City Council’s consideration and discussion.

FISCAL IMPACT: The current cost of the City’s weed eradication program is estimated at $300,000 per year, and the estimated cost per year for the proposed program is about $500,000, or an additional $200,000 in material and labor costs. The higher cost is due to the higher product cost of the natural and organic pesticide/herbicide, the increased frequency of application required, training for staff on use of newly acquired natural and organic pesticides/herbicides, and the corresponding increase of labor hours needed.

Dear Mayor Franklin, Deputy Mayor Contreras and City Council members Melendez, Green and O'Donnell:

I submit this letter in SUPPORT of of Item D1, 9 May 2023 City Council Agenda WITH AMENDMENTS.

Glyphosate - N- (phosphonomethyl)glycine
In 2015, the International Agency for Research on Cancer (IARC), an agency of the World Health Organization, brought together 17 independent experts from 11 countries to review four organophosphate chemicals, including glyphosate, to determine their potential to cause cancer. The year long process resulted in a 2A Classification (Probably carcinogenic to humans) due to the evidence of carcinogenicity in both experimental animals and humans.

IARC v. US EPA findings related to carcinogenicity of glyphosate:
"...EPA relied mostly on registrant -commissioned, unpublished regulatory studies, 99% of which were negative [emphasis added], while IARC relied mostly on peer -reviewed studies of which 70% were positive (83 of 118), (2) EPA's evaluation was largely based on data from studies on technical glyphosate, whereas IARC's review placed heavy weight on the results of formulated GBH [glyphosate based herbicides] and AMPA assays [aminomethylphosphonic acid]; (3) EPA's evaluation was focused on typical, general population dietary exposures assuming legal, food -crop uses, and did not take into account, nor address generally higher occupational exposures and risks. IARC's assessment encompassed data from typical dietary, occupational, and elevated exposure scenarios."
Glyphosate has been on the California Proposition 65 as a cancer causing agent since 17 July 2017 Health and Environmental Effects:
• Cancer
• Endocrine Disruption
• Reproductive Effects
• Neurotoxicity
• Kidney/Liver
• Sensitizer/Irritant
• Birth/Developmental
• Toxic to Birds
• Toxic to Mammals
• Toxic to Fish/Aquatic Organisms
• Toxic to Bees
• Lethal to amphibians

Glyphosate has been detected in soil, air, surface and ground water. To what degree is the City of Vista responsible for the ground water contamination from synthetic chemicals and to what degree does it wish to remain so? at are Groundwater Threats?

Neonicotinoids
, "9D S7w,
Ch UNITED STATES ENVIRONMENTAL PROTECTION AGENCY
��K%J https://www.epa.gov/system/files/documents/2023-05/ESA-JAM-Analysis.pdf In 2022, the US EPA released biological evaluations on three neonictinoids, revealing the harm caused to the vast majority of endangered species: clothianidin (1,225 species, or 67% of the Endangered Species Act [ESA] list), imidacloprid (1,445, 79%), and thiamethoxam (1,396, 77%).

The Center for Biological Diversity says the above report, released by the EPA on 1 May 2023, is a "Five Alarm Fire". The report reveals that neonicotinoids threaten the continued existence of over 200 plant and animal species. "As CBD [Center for Biological Diversity] pointed out: "For decades the EPA has refused to comply with its Endangered Species Act obligations to assess pesticides' harms to protected species. The agency was finally forced to do the biological evaluations by legal agreements with the Center for Food Safety and the Natural Resources Defense Council. After losing many lawsuits on this matter, the EPA has committed to work toward complying with the act."
"Given the Fish and Wildlife Service's refusal to lift a finger to protect endangered species from pesticides, we commend the EPA for completing this analysis and revealing the disturbing reality of the massive threat these

pesticides pose, "said Burd. "The Biden administration will have the stain of extinction on its hands if it doesn't muster the courage to stand up to Big Ag and ban these chemicals." "Neonics" are the most often used class of pesticides in the United States, despite the US EPA finding that "...neonicotinoid seed treatments likely provide $0 in benefits to growers and at most $6/acre in benefits (i.e.,a 0%-1.7% difference in net operating revenue)."i20i The UN warned in 2017 that 40% of invertebrate pollinators (bees, butterflies) are at risk of global extinction.

Bees and other pollinators (birds, butterflies, bats, beetles) are responsible for greater than 75% of the yield and quality of the world's food crops. The use of synthetic pesticides, climate change, loss of biodiversity, pollution and intensive agricultural production have contributed to a loss of up to 90% of the bee population through "colony collapse disorder." While western honey bee populations are relatively stable in the US, they and 20,000 wild bee species and other pollinators remain at risk globally.

Birds and other animals that rely on affected and dead insects for their diet are also being impacted by neonicotinoids: affecting fat stores through appetite suppression, migration patterns required for survivability, and reproductive capability, High doses of neonicotinoid exposure, the equivalent of 1/10 of a sunflower seed, has been shown to result in a 6% loss in body mass within 6 hours in birds.

Despite manufacturer claims of "...relatively soft on beneficial species and can be used in harmony with honey bee pollination programs," these chemicals induce a high level of addiction in bees, like nicotine addiction as expressed in the name of the class of these pesticides. It has been shown they they reduce bee sperm count and quality and negatively impact their memory and homing ability, contributing to colony collapse disorder.

Birds and other animals that rely on affected and dead insects for their diet are also being impacted by neonicotinoids:
affecting fat stores through appetite suppression, migration patterns required for survivability, and reproductive capability. High doses of neonicotinoid exposure, the equivalent of 1/10 of a sunflower seed, has been shown to result in a 6% loss in body mass within 6 hours in birds and a total net loss of 17%. Studies have shown that birds that ingested neonicotinoid coated seeds required more 3 days to recover from lethargy and regain weight, delaying migration and potentially missing the opportunity for reproduction. Birds can be exposed at additional way points during migration, as well. A lethal dose of neonicotinoid is the equivalent of Many small birds only reproduce once or twice in their lifetime and their populations are plummeting.

In humans, neonicotinoid pesticides have been shown to have endocrine disrupting and reproductive effects, including congenital anomalies, spontaneous abortions, preterm birth, low birth weight, and prolonged gestation, all of which can have long term health implications. Neonictinoids cross the blood brain barrier and low level and chronic exposures can result in neurotoxicity, immunotoxcity, genotoxicity and endocrine toxicity. Acute toxic exposures can be lethal. They are toxic to both vertebrate and invertebrate aquatic organisms, have a long term effect on the aquatic environment, and impact the food you eat and the water you drink.

Neonics persist in the soil for years after application and run off into waterways and oceans. Even when low levels are detected, their effects can be cumulative, affecting crops, humans, other mammals and aquatic life. Developing fetuses and children are disproportionately affected because of their immature systems and size.

Fluorinated pesticide storage containers
WHERE ARE GLYPHOSATE, DITHIOPYR AND OTHER CHEMICALS BEING STORED IN VISTA? In March 2021, the US EPA issued a memorandum regarding per- and polyfluoroakyl substances (PFAS) leachate from high density polyethylene (HDPE) plastic containers used to store pesticides. Six PFAS compounds were found to leach from the containers, posing a danger to humans and the environment. o "k%

BACKGROUND
The EPA's Analytical Chemistry Laboratory at Fort Meade has tested a limited number of Fluorinated and non -fluorinated HOP {High Density Polyethylene) containers for presence of PFAS (Per -and Polyfluoroalkyl Substances). This effort is in support of the Agency's investigation on the source(sj of PFAS found in a mosquito control pesticide product. This memorandum summarizes our findings and discusses the limitations of the results.

The EPA also tested a limited number of samples of a mosquito control pesticide product collected at different steps in the production and manufacturing of that product, the final results of which will be reported in a separate memorandum (after review by cur Quality Assurance Officer (QAQ) for compliance with the ISO-17025 guidelines}. Preliminary results of this analysis are discussed briefly in this memorandum in terms of theiroveraII trend.

SUMMARY OF RESULTS
The data included in this report represent results from testing the following H D P E container samples, which are submitted by the producer of the pesticide product. All fluorinated containers were of the same fluorination level (Level3), which is specific to the manufacturer; One (1) fluorinated HOPE 2.5-gallon jug that previously contained the product (used) (Twojugswere received, of which one was analyzed.)
Two (21 fluorinated HDPE 2.5-gallon jugs that never contained the product (unused) Two (2j fluorinated HDPE SS -gal Eon drums that never contained the product {unused} Two (21 fluorinated HDPE 30-gal Eon drums that never contained the product (u nused j Two (2) non -fluorinated HID PE 2.5-gallon jugs that never oontained the product (unused)

The EPA Performed a rinse procedure on the containers and analyzed the rinsates using the modified EPA Method 537.11. The following PFAS compounds were positively Identifed:

Subsequent studies done by the US EPA has shown that leaching of these toxic and carcinogenic chemicals continues over time. This has also been found to be true of fluorinated plastic food storage containers. Testing of fluorinated plastic food containers by the leading researchers of PFAS in consumer products at University of Notre Dame found 9 PFAS compounds in food containers. and also found that the chemicals leach into food within seven days and that exposure to elevated temperatures (50oC/1220F(, such as during transport or storage, increases PFAS leachate by up to 830%.

Human and Environmental Health risks from PFAS
Testimony of Dr. Jaime DeWitt before US Congress in 2019:
':..even of humans who are exposed by everyday activities have uncovered adverse health effects to include kidney and testicular cancer, decreased antibody response to vaccines, liver damage, changes in serum lipids and cholesterol, increased risk of thyroid disease, increased risk of asthma, increased risk of thyroid disease, increased risk of decreased fertility, decreases in birth weight and increased risk of pregnancy -induced hypertension and

preeclampsia. PFAS are truly "multi -system toxicants" These forever chemicals possess tremendous risks to Public Health — they are Persistent in the environment and in human bodies, the eioaccumulate from the environment into the bodies of living organisms."
Since Dr. DeWitt's testimony, additional effects of PFAS exposure have been found:
"..endocrine function including pancreatic dysfunction and risk of developing Type 2 diabetes, lipid metabolism and risk of childhood adiposity, hepatic and renal function, immune function, cardiovascular health (atherosclerosis), bone health including risk for dental cavities, osteoporosis, and vitamin D deficiency, neurological function, and risk of developing breast cancer." They can be neurotoxic, are associated with autism spectrum disorder, and an increasing number of cancers.

More than 330 species have been found to have PFAS chemicals in their their blood and organs. To use synthetic pesticides (pesticides/herbicides/rodenticides) that contain PFAS, whether intentionally added or leached into storage containers is to contribute to a lose of biodiversity and threaten a collapse of the food chain.

PFAS are known for being very environmentally stable and can persistent in the soil, particularly with historic and repeated applications.

Your IPM is proposing to continue spraying along major thoroughfares throughout the city, immediately adjacent to residential areas as well as along the freeway. There is a likelihood for harming vulnerable populations, including children and adolescents, pregnant individuals, the elderly, and homeless. Pets and wildlife will also be impacted.

Monsanto, now Bayer -Monsanto, has had little respect for a call for change or regard for human health and environmental health, as demonstrated by Monsanto's Dr. Daniel Goldstein in email communications with Monsanto consultants (2017). As servants of the people of Vista, please respect the many requests for a comprehensive organic Integrated Pest Management program than reduces subjectivity of decision making by:
• Reducing the number of persons with authority to move to synthetic chemical use • Providing training and certification in organic land management to select staff with an earnest interest in and commitment to success. This need is evident from the noticed misbelief that organic land management is a product swap- from synthetic to organic product use.
https://nofa.organiclandcare.net/nofa-accreditation-course-in-organic-land-care/ • Removal of the harmful synthetic chemicals
• Disallowing synthetic chemical use on major thoroughfares due to residential properties, school proximity and bus stops; the 78 freeway where slopes would require broadcast spraying. Removal of these products necessary to avoid detrimental human and environmental impacts (including climate change, not covered in this letter).

Please stop using toxic pesticides in all city parks, medians and city properties. Our public parks and green spaces are an important pace for hope, serenity, and wellbeing. These parks provide connection with our living environment from the soil, vegetation, and wildlife all of which depend on healthy environments. Our health is intricately connecting to the health of nature around us, and in order to ensure these places thrive for generations to come we need to stop using toxic pesticides. I am writing for support of passing the IPM, Integrated Pest Management Plan because its what our children and green spaces deserve.

Please protect our children, families and water from toxic pesticides. Please stop using toxic pesticides in all city parks and properties. (Currently you are using glyphosate and dithiopyr which are very toxic and known to drift.) City of Vista, please pass an IPM (Integrated Pest Management) plan like the City of Malibu and many other cities. A good IPM requires you to write down and solve problems of weeds, ants ... without toxic synthetic/man-made pesticides. Pesticides are toxic.

Please stop using all synthetic (man-made) pesticides and fertilizers in parks, medians and Vista City lands or leased lands. We must protect public health, our air, water, birds, butterflies, our pets and the environment. Please use an IPM like Malibu and many other cities. Thank you.

Dear City of Vista,
I am writing to urge you to take action to protect our community's children, families, pets, and environment from the harmful effects of toxic pesticides. Specifically, I am calling on the city to cease using synthetic/man-made pesticides, such as glyphosate and dithiopyr, in all city parks, medians, and properties.

These pesticide ingredients are well -documented to be toxic and known to drift, putting our community at risk. We must prioritize the health and safety of our children and take action to eliminate these hazardous substances from our public spaces.

I strongly encourage the City of Vista to adopt an Integrated Pest Management (IPM) plan, which has been proven effective in many other cities, including the gold standard IPM plan used by the City of Malibu. An IPM plan would provide a comprehensive and sustainable approach to managing pests while minimizing risks to human health and the environment.

I urge you to prioritize the adoption of a high -quality IPM plan for the City of Vista and to immediately stop using all synthetic (man-made) pesticides and fertilizers in parks, medians, and all city lands and leased lands. Our children deserve nothing less than the best when it comes to their health and safety.

Please take swift and decisive action to protect our community from toxic pesticides.

Dear City of Vista,
I am writing to implore you to protect our children, families, and water from toxic pesticides by eliminating the use of toxic pesticides in all city parks and properties.

Stop using toxic chemicals like glyphosate and dithiopyr which drift into air and water sources! City of Vista, I call on you to pass an IPM (Integrated Pest Management) plan. Just as other cities like the City of Malibu have risen to stop toxic pesticides I believe that you will make the right decision to keep your citizens, our families, safe. A good IPM will require you to write down and solve problems of weeds, and ants without toxic synthetic pesticides, a critical step to ensure the safety of our children as they grow and play. Please stop using all synthetic (man- made) pesticides and fertilizers in parks, medians, and on Vista City lands or leased lands. It is urgent that you protect public health, our air, water, birds, butterflies, pets, and the environment. Take the first step to elimnate toxic pesticides today! Thank you.

Dear City of Vista,
Please stop using toxic pesticides in parks, on medians, on leased lands, and on all city properties.

These pesticides endanger our kids and our pets, as well as the wildlife in the area.

They are terrible poisons and you must stop using them.

Your staff report shows that you are using glyphosphate and dithiopyr, known to be toxic. And they drift in the air, spreading their toxic effect.

The City of Vista must pass an IPM, Integrated Pest Management plan, as many cities have already done. The City of Malibu IPM is the gold standard. Please follow that. You owe it to our children.

Dear City of Vista,
Please protect the health of our children, families, pets, wildlife, and environment by prohibiting the use of ALL toxic pesticides and synthetic fertilizers in city, parks, medians, and city properties.

According to your staff report, Vista is still using glyphosate and dithiopyr, which are ingredients that are toxic and known to drift. I urge to city of Vista to pass an Integrated Pest Management plan like the city of Malibu and other cities have already done.

Many of these toxic pesticides are putting pollinators at a huge risk of extinction, which gravely threatens our global food supply. Pollinators are responsible for about one in three bites of food we eat. When pesticides drift, they contaminate our air, water and environment, which is especially dangerous for our children. Also, low income, communities and communities of color are exposed to more dangerous, environmental contaminants than their white counterparts, making them known as sacrifice zones and causing them to experience frequent and chronic health conditions, weakening their immune system, which makes them more likely to get sick and die from diseases like COVID-19. Some of these pesticides also cause cancer, developmental, and learning disabilities and more.

There are a couple of essential oils that are known to be pest and bug repellents, and though I may not know all of the non -toxic alternatives, I suggest The city of Vista to look to other cities that have completely banned toxic and synthetic pesticides and fertilizers for references to what can and should be used in the city instead. thank you.

PESTICIDES AND CHEMICALS USED IN CITY PARKS AND STREETS Weed Control Approaches Used:
•Tiered approach to protect human health and environment •Mechanical/physical control preferred
•Chemical control only when/where necessary
•Used in combination to increase their effectiveness
Pesticide (Chemical) Use Guidelines:
•Used only when/where needed –approved by Supervisor/Manager •Selected and applied to minimize their possible harm to people, non- target organisms and the environment.
•Example use: removal of invasive plants in open space areas

Permits and Training:
•CalAgPermits -statewide Pesticide Permitting and Use Reporting system for regulators, agriculturalists, and both public and private pest control operators in every California county.
•All chemical/pesticide safety and warning labels followed strictly •Personnel/contractor trained/certified annually
•Applied by a valid CA Qualified Applicators License holder city employee or under his supervision

PESTICIDES AND CHEMICALS USED IN CITY PARKS AND STREETS

PROPOSED APPROACH: INTEGRATED PEST MANAGEMENT
•Prepare and adopt integrated pest management (IPM) plan •Manage chemical herbicide use based on risks to residents and City staff •Avoid chemical herbicide use in more heavily used areas •Parks
•Along streets: high foot traffic areas
•Along streets: areas close to schools
•Chemical herbicide spraying continued in other areas along streets •Avoids need for staff to hand weed along high speed roads (safety) •Avoids need for lane closures and traffic impacts

PROPOSED APPROACH: PARKS
Proposed Approach Avoid chemical herbicide use*
Rationale People usually present, including
children and elderly
Main Method Mechanical (hand removal)
Supplemental Method Organic herbicides
Change Compared to
Current Approach Moderate
*Retain ability to use as last resort in emergency situations

PROPOSED APPROACH: STREETS BY SCHOOLS AND IN DOWNTOWN
Proposed Approach
Avoid chemical herbicide use along
streets within 0.25 mile of schools
and in Vista Village area*
Rationale Higher foot traffic areas, children
often present
Main Method Mechanical (hand removal)
Supplemental Method Organic herbicides
Change Compared to
Current Approach Moderate
*Retain ability to use as last resort in emergency situations

PROPOSED APPROACH: OTHER MAJOR CITY STREETS/MEDIANS
Proposed Approach Periodic chemical herbicide use, 2-4
times per year
Rationale
-Lower or no pedestrian use
-Large traffic impacts and increased
staff safety risk if switched to hand
removal
-Consistent with Caltrans approach
Main Method Chemical herbicides using truck or
trailer mounted sprayer
Change Compared to
Current Approach None

SUMMARY AND COST IMPACTS
Proposed Approach
•Transition to IPM approach in areas
people are more likely to be present
•Estimated cost increase: $300,000 -
$400,000/year
•Increased labor for hand weeding
•Training on use of organic
herbicides
•Purchase of organic herbicides
•Cost likely to be higher in years with
more rain, lower in years with less rain
