Environmental Program Manager I: Janna Rinderneck
Janna began work for the department’s Water Pollution Control Laboratory in 1986, conducting pesticide extractions and analysis, while pursuing her Bachelor of Science in Biological Conservation. After graduation, she gained experience in fisheries, bioassay, and laboratory auditing, until serving from 1998 to 2011 as CDFW’s statewide expert and technical specialist for hazardous material spill response and inland oil spill response. After supervising the Petroleum Chemistry Laboratory for four years, Janna became Environmental Program Manager for the OSPR Laboratory Program, overseeing five field and laboratory functions: The Petroleum Chemistry Laboratory, the Water Pollution Control Laboratory, the Aquatic Bioassessment Laboratory, the Marine Invasive Species Program, and the Marine Pollution Studies Laboratory. The projects include a statewide field bioassessment program and chemical analysis for spill responses as well as supporting various other CDFW programs.
Prevention Branch Chief: Ted Mar
Ted came to OSPR after more than 22 years with the U.S. Coast Guard, where he was stationed at Marine Safety Offices (MSOs) in Los Angeles-Long Beach and San Francisco, and was the Assistant Chief of the Marine Safety Division at Pacific Area/District Eleven in Alameda. He received his Bachelor of Science in Chemistry with high honors from the U.S. Coast Guard Academy, and was sent to UCLA for graduate studies in Chemical Engineering. After spending time with the Coast Guard’s Central Oil Identification Lab as a cadet, and assignments as the Marine Environmental Response Officer at two MSOs, Ted became convinced that oil spill prevention was a better time investment of personnel resources than continuing to respond to spill after spill. Ted left OSPR to become the supervisor of the State Lands Commission’s Marine Facility Division Northern California Field Office, then returned to OSPR to advocate for improved oil spill prevention practices as its Marine Safety Branch Chief. The Marine Safety Branch was renamed the Prevention Branch when OSPR assumed statewide responsibility for oil spills.
