Kourtney Kardashian Barker joined protesters on Thursday, who continued to express their opposition to a plan that brings thousands of tons of ash and debris from the recent wildfires to the Calabasas Landfill in Agoura Hills.

The plan involves bringing up to 5,000 tons of debris from the recent wildfires, including the Palisades Fire, to the landfill each day.

Ash can contain lead, other heavy metals, and various toxic compounds, and scientists say any amount of lead exposure is potentially dangerous.

Since Feb. 15, protesters have been at the landfill site demanding change.

The POOSH founder wasn’t the only public figure in attendance. Kendra Wilkinson, the ex-girlfriend of Hugh Hefner, the founder of Playboy Magazine, shares moments from the protest on her Instagram.

“Stop the toxic waste dumping around our schools and residential areas!!!” the Instagram post caption said.

The Calabasas City Council recently wrote a letter to the L.A. County Board of Supervisors opposing the plan.

“The City Council is compelled to echo the public sentiment that the urgency of the recovery phase and efforts to remediate one disaster is laying the foundation for future public health and environmental catastrophes that will affect Calabasas residents,” city leaders wrote.

Despite vocal opposition, the Board of Supervisors recently agreed to temporarily remove dumping restrictions at the Calabasas Landfill, allowing it also to accept fire debris, according to the Los Angeles Times.

The landfill is typically restricted to waste only from Calabasas, Hidden Hills, Agoura Hills, Malibu, Westlake Village, Thousand Oaks, some parts of Los Angeles and select incorporated areas

The board’s vote will allow the landfill to accept material from outside that area for six months, with possible extensions.

County leaders have said they understood the public’s concern but noted that landfills face strict regulations about handling fire waste, and there was little chance of toxic waste escaping into the air.
