-4. DELIBERATE and TAKE ACTION at the discretion of the Planning Commission, including considering adoption of Resolution No. 26-2900, entitled, "A RESOLUTION OF THE PLANNING COMMISSION OF THE CITY OF CARSON DENYING SITE PLAN AND DESIGN REVIEW NO. 1935-23 AND CONDITIONAL USE PERMIT NO. 1128-23, AND RECOMMENDING THAT THE CITY COUNCIL DENY DEVELOPMENT AGREEMENT NO. 33-23 FOR A PROPOSED BATTERY ENERGY STORAGE SYSTEM (BESS) FACILITY LOCATED AT 18800 BROADWAY AVENUE, APN 7339-014-009".

Vice Chair Diaz - Out of all the residents and stakeholders in the outreach process, what percentage would you say expressed any opposition to the project if any?

Senior Planner Pompey - The applicant may be better able to answer that question.

Planning Manager Alexander - Can you advise the commission the number of applicants that arrived, attended the previous meeting and compare that to the number of mailing that were sent out.

Senior Planner Pompey - I was involved in the last two neighborhood meetings. I believe about 6 residents and parties attended in January and between 8 to 10 individuals in February.

Planning Manager Alexander - Approximately how many mailers went out? Maybe Planning Secretary Gonzalez can confirm that.

Planning Secretary - 174 mailers.

Vice Chair Diaz - Out of those that attended the meetings in January and February, what would be the percentage against the project versus those in favor of going through with the project? Is there a correlation?

Senior Planner Pompey - I believe everyone who attended supported the project.

Vice Chair Diaz - For our vital infrastructure projects, whether they are gas lines, gas station tanks, electricity lines, sewage plants, etc., are you able to say with 100% assurances that there will never be an accident?

Senior Planner Pompey - No.

Commissioner Johnson - What's the reporting radius for the notices?

Senior Planner - We mailed out 1000 feet radius for tonight's public hearing as well as the last neighborhood meetings.

Planning Manager Alexander - The typical is 750 feet radius. To make sure we reached out to the community, we expanded to 1000 feet.

Vice Chair Diaz - Has the Fire Department signed off on this project?

Senior Planner Pompey - The Fire Department reviewed the applicant's submittal of an alternative materials and methods report.

Planning Manager Alexander - The L.A. County Fire Department provides the report and the information regarding the project as well as mitigation measures. They are not the deciding body in terms of approval. They provide the technical review of this project.

Chair Thomas - I have major concerns about the proximity to the hospital and residential homes. Can you guarantee this city 100% that this project is safe and there will be no issues?

Richard Stillwagon (L.A. County Fire Dept.) - With any project, we can't guarantee 100% safety. 

Chair Thomas - We know there are things that have happened in multiple communities across the country. There's always a potential for something to happen. What would happen if there was a fire at this location? How would you be able to mitigate that?

Richard Stillwagon - We have several tactics we utilize in the fire department. We work with the applicant at the end of the construction where we are trained. We train everybody in the battalion and the neighboring battalions to respond to an incident, learning all of their safeguards and all their security measures for ensuring that an incident stays as small as possible and hopefully in this case confined to the container of origin, which has been the history of what we've seen with BESS fires throughout the State of California and nationally. Once we respond to the incident, we evaluate the incident as we do with all of our incidents, and then we take the best appropriate tactical measure moving forward. The challenge with BESS fires is that they are a container within a container. As we apply our normal traditional method of extinguishment, water rains down over the overall container, thus not allowing us to penetrate where the active fire is, so that becomes the challenge. However, there are mitigation tools that we can utilize with active hose streams to umbrella a container, which is best practices to prevent lateral spread from container to container throughout the farm in the field. We also have separation distances which help prevent the spread between battery energy storage systems throughout the energy field. The other item is to utilize hose streams on the neighboring unit to cool it and to prevent it from catching fire, that way it can't spread outside of its origin. The rain-down effect absorbs a lot of the heat, the combustion particles, and the chemicals coming off of the fires. Ultimately, the fires burn themselves out, just like a Tesla vehicle fire, but these are on a bigger scale. I'm very familiar with the technology that's being proposed here. The Tesla Megapack 2 is excellent technology and has excellent safety built-in procedures. They followed all the California fire code requirements, which includes a detection source. We want to get early detection. We want notification to our emergency first responders to initiate action and get on the scene as fast as possible. Secondly, that indicator puts off an alarm device. The alarm device is loud to clear everybody out of the immediate area to ensure public safety and anybody doing business on site. Finally,  we have water system on site to utilize and keep these incidents small. The actual ignition source is built into these systems. If they have a gas leak detection , they have a sparker system that lights the gas on fire. They do that to prevent explosions. They want to prevent bigger or greater hazards. That's the way the technology is designed to work and consume itself. 

Chair Thomas - When you say burnout, explain what needs to happen.

Richard Stillwagon - We allow the hazardous materials to burnout or extinguish themselves. In this particular case, hydrogen gas and carbon monoxide gas are released. Hydrogen gas burns at 1700 degrees plus Fahrenheit which consumes most of the other chemicals within the burning process. This is why we believe that we haven't seen larger amounts of chemical readings off the sites during a BESS fire.

Chair Thomas - Is there a chance that there can be an explosion? What would be the ramifications of an explosion?

Richard Stillwagon - There are two types of containers. There are closed containers where they use a ventilation system to prevent the explosion. Then the megapacks that are used here in this scenario, which the igniter system ignites and thus prevents the explosion. Should the igniter system fail across the board, then you could get a gaseous buildup and then an explosion could occur. We've seen explosions and ruptures in small areas of the container. We've never seen a full scale container explosion, however, we do have all of our companies model to that effect for first responder safety. As we respond in incidents, we want to know what the setback distances are so we can be safe and then approach accordingly. Then they become our evacuation distances.

Chair Thomas - While you're assessing these kinds of conditions, is the neighborhood waiting for you to tell them to evacuate?

Richard Stillwagon - No, the large alarm system that is on site notifies the whole neighborhood. The neighborhood is going to know they need to evacuate when they hear that sound.

Chair Thomas - We're hoping people hear that sound and don't ignore it.

Richard Stillwagon - It's twofold, (1) that is the initial warning sound and then (2) working with law enforcement to evacuate the area needed.

Chair Thomas - I'm asking all these questions because we just went through the fires that took place in Altadena and Palos Verdes a year ago. Residents said they never heard an alarm. Can you give your assurance that is something our residents don't have to worry about? Would you as a Fire Chief give your assurance that those concerns are not valid?

Richard Stillwagon - The California State Fire Marshal's Office says that anything over 600 kilowatt-hours in an utility BESS scale facility has a 50 foot setback from hospitals, schools, and other sensitive receptors including residential. That's the California State Fire Marshal's ruling, and I work for the California State Fire Marshall.

Chair Thomas - Are they saying there are no worries because of the setback?

Richard Stillwagon - That's what the code reads and that's what I'm bound to, it's the law. An applicant  meets the application of the law, them I have to approve the project.

Chair Thomas - I'm not feeling reassured. Someone has to be looking out for the those residents who didn't get to attend the community meeting and for those that didn''t even know the meetings happened. I'm not hearing that there's no chance that anything could potentially happen there. No one is giving me that assurance.

Richard Stillwagon - In L.A. County we have the most strict requirements in the entire nation. We're leading the nation in safety requirements. The 10-foot wall that is engineered to withstand any blast was designed to limit that explosion. We utilize a 10-foot wall because the containers themselves are 10 feet and the actual hazardous material is below that level. It's national and state practice to have a wall that's 18 to 36 inches above the hazardous material to contain all products. If there was a concern about that blast one of the mitigating measures would be to elevate the height of the wall to a 13 feet level which would then give you that 36 inch clearance, but that would be a condition of the applicant.

Chair Thomas - With the connectivity that's taking place at the substation, there are other toxins that could potentially escape in the event of an incident. Would they not clear the wall?

Richard Stillwagon - When we have these types of fires, the toxicity in outdoor BESS facilities has not put up any readings during emergency incidents that have cleared the site. We don't have any data that supports that. There were incidents throughout California where they did have vapor exposure offsite, but was with older technology with heavy metal batteries and it was in a contained building. The building kept burning, thus reigniting the battery cells, thus keeping this prolonged exposure. Here in L.A. County, I have never approved nor will approve that type of facility because of its dangers and hazards. We move to the outdoor container as a best solution to that problem.

Chair Thomas - We don't have any data that tells us it can't happen.

Richard Stillwagon - No, I think you would be looking for a toxicology report from the applicant. They could do a toxicology report during a large fire test that could show the actual vapors that are coming off the chemical exposure and then they could do modeling behind that.

Vice Chair Diaz - What gave you the confidence to sign off on this project?

Richard Stillwagon - We are leading the nation in safety in the space, and we have higher regulatory requirements than anybody else in the state. Nobody requires a blast wall. We demanded our applicants to provide the explosion modeling to where we could provide a reinforced wall to keep fires and explosions contained withing sight. That is a higher level requirement. We were the first in the nation to require and demand internal gas detection systems and or smoke systems to get that early warning and to let everybody evacuated the area. There is some public outreach that the applicant has to do to make notifications of when they hear this sound, here's best practices in that space. We are leading the nation throughout all the departments. We are working with the Department of Energy. We also have a member of our department who is one of the voting members for the California entity that's been set up to start looking into the space and for the regulating as we move into the commercial space with the smaller units. He also sits in the larger NFPA committees to make sure that we're abreast of all the situations that are going on within the codes committee. We're giving our experience, we're leading the way in the national discussion, and then we are partnering with the State Fire marshal's Office working with all the departments in California that have had incidents to learn our lessons and move forward. The California Fire Code says that a battery energy storage system can be 25 feet from a building if it has a 2-hour firewall. The walls that are being built on these facilities are 4-hour rated against fire. That doesn't eliminate or take away all hazards but those are emergency response hazards that happen with every institution, every building, every chemical on earth. As one of the leading fire departments, we have the capacity to respond to all incidents. We are an all risk organization and we will respond and take care of those situations. If we have evacuation needs we'll ensure the safety of the public in those evacuations. We have the reverse 911 system that can be pre-programmed for this facility as a quick outreach to our local citizens to let them know there's a hazard in the area and give them directions and instructions. The Sheriff's Department handles that side of things. The mitigating factors containing the process or limiting the exposures to one container or one group of containers is our goal, we feel we have done that. I signed off on the alternative materials and methods because they provided those mitigating measures. I like the idea of the toxicology report. I think that would be a great going forward if the commission decides to go in that direction and/or increase the barrier wall height which would then not only get the lateral spread. In an explosion, we were most concern about the lateral spread of debris. That's what could threaten a life or harm individuals.

Commissioner Huff -  Has there been any testing when it comes to smoke or any other particles that are able to escape and go over the wall?

Richard Stillwagon - Our review is specifically for the property of origin and mitigating the hazards on site.

Commissioner Huff - What would you say the value of this report should be used for?

Richard Stillwagon - The value of the Alternative Materials and Methods Report is the quantities in the battery energy storage system space have exceeded the normal quantities that the fire code was written for. Once we exceed those requirements, we go to a utility scale requirement. When we're dealing with utility scale requirement we put in all the safety measures. The fire chief of Los Angeles County has committed to following every law and safety measure that is applicable in this space. We have to apply all of the safety mitigation factors. When you look at safety, it's not in a single item. It's the design of the product, it's the battery energy management storage system module that contains the energy flow within the unit. I look at all hazardous material throughout L.A. County all the way up until nuclear. We utilize the same hazard MMR process with anything that
