One of the largest conservation groups in the country has its sights set on Orange County\u2019s Prima Deschecha landfill, questioning if county officials should move forward with plans to double the amount of trash going there every day.<\/p>\n

Conservationists say the landfill expansion could threaten the local mountain lion population in South OC by destroying their habitat \u2013 potentially driving OC\u2019s large felines to extinction.\u00a0\u00a0<\/p>\n

The questions come after a series of residents raised complaints, highlighting that the landfill expansion is already carrying a massive impact on their neighborhoods with increasing traffic, air pollution and noise.\u00a0<\/p>\n

The plan is also facing questions from several cities near the landfill about how mitigation of the construction and traffic will be handled, submitting multiple complaints about the county\u2019s environmental review of the plan.\u00a0<\/p>\n

Now, those questions are being joined by the Center for Biological Diversity, one of the county\u2019s largest environmental nonprofits with over 1.8 million members and a history of activism and litigation.\u00a0<\/p>\n

In a May 29 letter to the county, staff from the center raised questions over the landfill\u2019s impact on nearby mountain lions.\u00a0<\/p>\n

\u201cThe mountain lion population in the Project area is facing an extinction vortex driven by habitat loss and fragmentation, vehicle strikes, rodenticide poisoning, disease, and other causes,\u201d wrote Scott Coberg, a legal fellow for the Center. \u201cThe Project will further destroy habitat, degrade connectivity, and drive the local mountain lion population closer to extinction.\u201d\u00a0<\/p>\n

County staff from the OC Waste and Recycling division declined to comment on the letter Monday morning. <\/p>\n

Coberg noted that the existing environmental plans don\u2019t do enough to help mountain lions that were recently \u201cprotected under the California Endangered Species Act,\u201d according to his letter.<\/p>\n

The Santa Ana population has the lowest genetic diversity documented for the species aside from the endangered Florida panthers,\u201d Coberg wrote. \u201cScientists predict that if further genetic isolation and inbreeding depression occur, this population has a 100% chance of becoming locally extinct within 50 years.\u201d\u00a0<\/p>\n

In his letter, Coberg noted that the county\u2019s last environmental study for the landfill was in 2007, years before the studies highlighting the problems facing mountain lions were completed, and that the county needs to examine how their work will impact mountain lions.\u00a0<\/p>\n

He also noted the center could be headed toward legal action.\u00a0<\/p>\n

\u201cGiven the possibility that the Center will be required to pursue legal remedies in order to ensure that the County complies with its legal obligations including those arising under CEQA, we would like to remind the County of its statutory duty to maintain and preserve all documents and communications that may constitute part of the \u2018administrative record,\u2019\u201d Coberg wrote.<\/p>\n

In a statement to Voice of OC, Coberg said the center had not yet made a decision to move forward with litigation, but noted that the county needs to update its review regardless.\u00a0<\/p>\n

\u201cMountain lions are a threatened species in Southern California, which means the county must be thorough in considering the landfill expansion\u2019s consequences for sensitive habitat,\u201d Coberg wrote.\u00a0<\/p>\n

\u201cUsing an environmental review that\u2019s nearly 20 years old and that focused on a much smaller operation just doesn\u2019t cut it. I urge the county to update its review so it reflects today\u2019s realities.\u201d<\/p>\n
