Fracking has been a hot topic on the Central Coast ever since the Trump administration released an environmental review about the possibility of expanding hydraulic fracturing on federal lands in Central California. We hear reactions from some in the neighboring community of Kern County to the plan. And Stanford geophysicist Mark Zoback explains some fracking basics, including what is and isn’t known about the technique's impact on the environment. We also talk about emergency preparedness in San Luis Obispo County. KCBX's Greta Mart sits down with county planner Jillian Ferguson and emergency services coordinator Scott Milner about how they are planning for possible future man-made and natural disasters. Also, if you’re a Democratic presidential primary voter, how will you decide who gets your support? We chat with four undecided California Democrats. And we previously reported that Santa Barbara’s landfill is filling up. Soon, in July, trash and recycling curbside services will go up. We’ll find out how the city plans to use the fees to in an effort help improve how the city manages recycling and trash.
