LAKE COUNTY, Calif. — Authorities are working to locate an Upper Lake man who is under investigation for an assault.
The Lake County Sheriff’s Office is requesting assistance from the community in locating Arturo Pedro Gutierrez, 62.
Gutierrez is a person of interest in an ongoing investigation, authorities said.
Sheriff’s spokesperson Lauren Berlinn said Gutierrez is wanted for an assault on a female that took place late on Aug. 18.
“The Major Crimes unit is working on this case,” Berlinn said.
Gutierrez is a registered sex offender as a result of a 2012 indecent exposure conviction, according to state records.
The Department of Justice has assessed Gutierrez as high risk for reoffense.
Anyone with any information as to his whereabouts is asked to call the Lake County Sheriff’s Central Dispatch at 707-263-2690.

LAKE COUNTY, Calif. — The Clearlake City Council on Thursday unanimously approved the purchase of a piece of property to build a new roadway for a major commercial development.
City Manager Alan Flora asked for, and received, the council’s approval to purchase the parcel at 6540 Old Highway 53 from AmeriGas for the appraised value of $110,000.
Flora explained that the property will be used for the construction of a new public roadway and future commercial development at the city’s former Pearce Field airport off of Highway 53.
He referred to the city’s purchase, approved in December but completed early this year, of some old mini storage buildings at 6461 Manzanita Ave. and 6452 Francisco Ave. for $550,000.
The parcels are located to the west of the Highway 53 and 18th Avenue intersection, on the edge of the Pearce Field property. A new road will be constructed through one of those parcels.
As part of that development, Flora said city staff had been trying to negotiate for the property for quite some time.
He said it had been a challenge to get responses from AmeriGas, which is located on the East Coast. “We believe we’re on the right track at this point.”
The city had performed an appraisal and got a title report to speed up the process, Flora said.
“This piece of property is necessary for the 18th Avenue road construction that we’re trying to finalize the plans on right now and hope to initiate construction on that project yet this year,” he said.
He said that AmeriGas had agreed to sell property to the city for $110,000. He hadn’t yet received the final agreement from them, which he said the company had been promising for a couple of weeks by that point.
In order to keep things moving, Flora said he wanted the council to authorize him to execute the documents needed to purchase the property as soon as he gets the documents from AmeriGas.
There was no public comment before Councilman Russ Cremer moved to approve the purchase, which was seconded by Councilman David Claffey and approved in a 5-0 vote.
The council on Thursday also held the first introduction for the first reading of an ordinance to update the municipal code to reflect the city’s migration from a traffic engineer to a city engineer model, approved the use and retention of the development impact fees for fiscal year 2021-22, and discussed the proposed bylaws amendments for the 2022 League of California Cities Annual Conference.

LAKE COUNTY, Calif. — Firefighters continued to work through the night to fully contain the Point fire burning new Lower Lake.
The fire was first reported shortly before 5:45 p.m. Saturday.
Cal Fire said it is located in the area of Anderson Road and Panorama Road, near Point Lakeview Road, west of Lower Lake.
It resulted in evacuation orders in two zones, KEL-E146-A and LOW-E154, that officials said remained in effect overnight.
Early estimates of the fire’s size put it at around 25 acres.
By Saturday night, Cal Fire had rolled back that estimate to 14 acres, with 20% containment.
There had been concerns about an area flaring up due to the fire, and firefighters remained assigned to the fire.
More crews and teams are due to report to the fire on Sunday, according to radio reports.

LAKE COUNTY, Calif. — The Clearlake Planning Commission this week will discuss a proposal to build a new adult residential care home on a property where a similar facility was destroyed due to arson five years ago.
The commission will meet beginning at 6 p.m. Tuesday, Aug. 23, in the council chambers at Clearlake City Hall, 14050 Olympic Drive.
Submit comments and questions in writing for commission consideration by sending them to Administrative Services Director/City Clerk Melissa Swanson at This email address is being protected from spambots. You need JavaScript enabled to view it.. Identify the subject you wish to comment on in your email’s subject line.
Community members also can participate via Zoom. The meeting also can be watched on the city’s YouTube account.
To give the planning commission adequate time to review your questions and comments, please submit written comments before 4 p.m. Tuesday, Aug. 23.
On the agenda is a proposal to build a new adult residential care facility for mentally ill adults at 14139 Konocti St.
The property previously was the location of the San Sousee adult residential facility, which was destroyed in January 2017 due to a fire set by a resident, as Lake County News has reported.

LAKE COUNTY, Calif. — The Clearlake City Council will hold a special meeting on Monday to discuss appointments to council seats and recruiting a new finance director.
The council will meet at 3:30 p.m. Monday, Aug. 22, in closed session to discuss a potential case of litigation before the public portion of the meeting begins at 6 p.m. in the council chambers at Clearlake City Hall, 14050 Olympic Drive.
Comments and questions can be submitted in writing for City Council consideration by sending them to City Clerk Melissa Swanson at This email address is being protected from spambots. You need JavaScript enabled to view it..
To give the council adequate time to review your questions and comments, please submit your written comments before 1:30 p.m. Monday, Aug. 22.
Each public comment emailed to the city clerk will be read aloud by the mayor or a member of staff for up to three minutes or will be displayed on a screen. Public comment emails and town hall public comment submissions that are received after the beginning of the meeting will not be included in the record.
On Monday, city staff will ask the council to discuss and provide direction on whether to appoint nominated councilmembers to serve another term in lieu of holding an election for those seats.
City Clerk/Administrative Services Director Melissa Swanson’s report explains that incumbent council members Russ Cremer and Dirk Slooten were the only ones to file to run for election in November.
“Because there are the same number of available offices and candidates, Elections Code § 10229 gives the City the option to appoint these candidates in lieu of holding an election,” Swanson wrote.
“Government Code 36512(d) prohibits an appointment that would result in a majority of councilmembers serving by way of appointment. For this reason, if the Council chooses to appoint the incumbents in lieu of election, if any future seat would become unfilled before the next election, the City Council would not have the option to fill the available council seat via appointment and would have to hold a special election at that time,” Swanson sadi in her report.
She said there were no nominations for city treasurer. Likewise, the city has the option to appoint a qualified elector to the city treasurer seat in lieu of holding an election or authorize the election for city treasurer to move forward, which allows for a candidate to be nominated during the write-in candidate period of Sept. 12 through Oct. 25.
Swanson said that city municipal code requires that whenever a vacancy occurs in the office of city treasurer, the city manager is automatically appointed to fill the vacancy until a successor is appointed or elected.
There has been no elected city treasurer filling the vacancy since 2006, Swanson said.
Swanson said the options include holding an election for all three seats, appointing Cremer and Slooten while holding an election in November for city treasurer, and appointing a qualified elector to the city treasurer seat and appoint the two qualified City Council candidates to the Council seats.
Also on Monday, City Manager Alan Flora will ask the council to consider hiring an executive recruiter to fill the upcoming finance director vacancy.
Flora’s report said that last week the city’s current finance director accepted a position out of state.
The city’s finance director, Kelcey Young, was hired in June 2021.
“Staff would like to move forward expeditiously to fill the upcoming vacancy,” said Flora, who is requesting authorization to select and contract with an executive recruiting firm to fill the vacancy.
Flora is asking to spend up to $30,000 on the recruitment.

LAKE COUNTY, Calif. — A late Thursday afternoon head-on crash near Upper Lake involving a pickup and a tractor trailer killed a Northshore man and injured three others.
The California Highway Patrol’s Clear Lake Area office said the wreck occurred at 4:42 p.m. Thursday on Highway 20 east of Bachelor Valley Road.
The Lake County Sheriff’s Office identified the person who died as John Steven Alvarez Sr., 68, of Nice.
The CHP report said that at 4:45 p.m. Thursday CHP Clear Lake units responded to the wreck.
The officers arriving on scene found a 2019 Volvo tractor trailer combination driven by 75-year-old Caroll Landers of Yuba City and a 2000 Ford Ranger pickup truck driven by Douglas Warren, 64, of Lucerne, were involved in the crash.
The CHP said Warren’s passengers were Alvarez and 58-year-old William Hughes of Willits.
Warren and Hughes sustained major injuries and were transported via air ambulance to Santa Rosa Memorial Hospital, the CHP said.
Authorities said Alvarez died at the scene.
Landers sustained minor injuries. The CHP said she was not transported to a hospital.
Based on the investigation so far, the CHP said it appears that Warren was traveling eastbound on Highway 20 and for unknown reasons crossed over the centerline and into the westbound lane of traffic, where his pickup collided with the front of the tractor trailer driven by Landers.
The CHP said Caltrans responded to the scene and assisted with traffic control.
The crash caused Highway 20 to be closed for approximately three hours, the CHP said.
Scotts Valley Road was used as a detour route until all lanes of Highway 20 reopened at 8:10 p.m. Thursday, according to the CHP.
All four of the crash victims were wearing their seat belts, the CHP said.
The CHP said the crash remains under investigation.

LAKE COUNTY, Calif. — The Board of Supervisors this week is set to consider the appeal of a cannabis grow, and discuss using a Northshore park as a community center during power shut-offs, continued operations of the former juvenile hall as a homeless shelter and a plan for a behavioral health treatment facility for youth.
The board will meet beginning at 9 a.m. Tuesday, Aug. 23, in the board chambers on the first floor of the Lake County Courthouse, 255 N. Forbes St., Lakeport.
The meeting ID is 993 2725 9180, pass code 236702. The meeting also can be accessed via one tap mobile at +16694449171,,99327259180#,,,,*236702#.
All interested members of the public that do not have internet access or a Mediacom cable subscription are encouraged to call 669-900-6833, and enter the Zoom meeting ID and pass code information above.
At 10:30 a.m. Tuesday, the board will take up an appeal that the supervisors themselves approved filing regarding the Lake County Planning Commission’s approval last month of a major use permit and initial study for a cannabis cultivation project for Bottle Rock Farms FJA Trust, located at 9900 and 100300 Bottle Rock Road, Kelseyville.
Supervisor Bruno Sabatier had raised the matter with the board at its Aug. 2 meeting due to several violations on the property which he said contradicted the commission’s approval action based on the county’s zoning ordinance.
At 1 p.m., the board will consider a license agreement between the county of Lake and PG&E for the temporary use of a portion of Lucerne Harbor Park as a community resource center in the event of a public safety power shut-off.
In an untimed item, staff is asking the board to discuss giving possible direction regarding the continuing operations of the homeless shelter at the county’s former juvenile hall in the wake of the announcement that Elijah House is ceasing operations of the facility in September.
Also in an untimed matter, the board will hear a presentation and discuss direction regarding a request for support for a plan for a behavioral health treatment facility for youth.
The proponents are planning to submit later this month for a $16 million grant. The presentation documents do not indicate where the facility would be located.

A. Daniel Jones, Michigan State University and Hui Li, Michigan State University
PFAS chemicals seemed like a good idea at first. As Teflon, they made pots easier to clean starting in the 1940s. They made jackets waterproof and carpets stain-resistant. Food wrappers, firefighting foam, even makeup seemed better with perfluoroalkyl and polyfluoroalkyl substances.
Today, PFAS are pervasive in soil, dust and drinking water around the world. Studies suggest they’re in 98% of Americans’ bodies, where they’ve been associated with health problems including thyroid disease, liver damage and kidney and testicular cancer. There are now over 9,000 types of PFAS. They’re often referred to as “forever chemicals” because the same properties that make them so useful also ensure they don’t break down in nature.
Scientists are working on methods to capture these synthetic chemicals and destroy them, but it isn’t simple.
The latest breakthrough, published Aug. 18, 2022, in the journal Science, shows how one class of PFAS can be broken down into mostly harmless components using sodium hydroxide, or lye, an inexpensive compound used in soap. It isn’t an immediate solution to this vast problem, but it offers new insight.
Biochemist A. Daniel Jones and soil scientist Hui Li work on PFAS solutions at the Michigan State University and explained the promising PFAS destruction techniques being tested today.
How do PFAS get from everyday products into water, soil and eventually humans?
There are two main exposure pathways for PFAS to get into humans – drinking water and food consumption.
PFAS can get into soil through land application of biosolids, that is, sludge from wastewater treatment, and can they leach out from landfills. If contaminated biosolids are applied to farm fields as fertilizer, PFAS can get into water and into crops and vegetables.
For example, livestock can consume PFAS through the crops they eat and water they drink. There have been cases reported in Michigan, Maine and New Mexico of elevated levels of PFAS in beef and in dairy cows. How big the potential risk is to humans is still largely unknown.
Scientists in our group at Michigan State University are working on materials added to soil that could prevent plants from taking up PFAS, but it would leave PFAS in the soil.
The problem is that these chemicals are everywhere, and there is no natural process in water or soil that breaks them down. Many consumer products are loaded with PFAS, including makeup, dental floss, guitar strings and ski wax.
How are remediation projects removing PFAS contamination now?
Methods exist for filtering them out of water. The chemicals will stick to activated carbon, for example. But these methods are expensive for large-scale projects, and you still have to get rid of the chemicals.
For example, near a former military base near Sacramento, California, there is a huge activated carbon tank that takes in about 1,500 gallons of contaminated groundwater per minute, filters it and then pumps it underground. That remediation project has cost over $3 million, but it prevents PFAS from moving into drinking water the community uses.
Filtering is just one step. Once PFAS is captured, then you have to dispose of PFAS-loaded activated carbons, and PFAS still moves around. If you bury contaminated materials in a landfill or elsewhere, PFAS will eventually leach out. That’s why finding ways to destroy it are essential.
What are the most promising methods scientists have found for breaking down PFAS?
The most common method of destroying PFAS is incineration, but most PFAS are remarkably resistant to being burned. That’s why they’re in firefighting foams.
PFAS have multiple fluorine atoms attached to a carbon atom, and the bond between carbon and fluorine is one of the strongest. Normally to burn something, you have to break the bond, but fluorine resists breaking off from carbon. Most PFAS will break down completely at incineration temperatures around 1,500 degrees Celsius (2,730 degrees Fahrenheit), but it’s energy intensive and suitable incinerators are scarce.
There are several other experimental techniques that are promising but haven’t been scaled up to treat large amounts of the chemicals.
A group at Battelle has developed supercritical water oxidation to destroy PFAS. High temperatures and pressures change the state of water, accelerating chemistry in a way that can destroy hazardous substances. However, scaling up remains a challenge.
Others are working withplasma reactors, which use water, electricity and argon gas to break down PFAS. They’re fast, but also not easy to scale up.
The method described in the new paper, led by scientists at Northwestern, is promising for what they’ve learned about how to break up PFAS. It won’t scale up to industrial treatment, and it uses dimethyl sulfoxide, or DMSO, but these findings will guide future discoveries about what might work.
What are we likely to see in the future?
A lot will depend on what we learn about where humans’ PFAS exposure is primarily coming from.
If the exposure is mostly from drinking water, there are more methods with potential. It’s possible it could eventually be destroyed at the household level with electro-chemical methods, but there are also potential risks that remain to be understood, such as converting common substances such as chloride into more toxic byproducts.
The big challenge of remediation is making sure we don’t make the problem worse by releasing other gases or creating harmful chemicals. Humans have a long history of trying to solve problems and making things worse. Refrigerators are a great example. Freon, a chlorofluorocarbon, was the solution to replace toxic and flammable ammonia in refrigerators, but then it caused stratospheric ozone depletion. It was replaced with hydrofluorocarbons, which now contribute to climate change.
If there’s a lesson to be learned, it’s that we need to think through the full life cycle of products. How long do we really need chemicals to last?
