Greg Pepping, Executive Director	As the Executive Director of the Coastal Watershed Council, Greg Pepping oversees all operations, bringing to the work of watershed protection his passion for all things related to water. He first realized the importance of water quality and public health issues as a Peace Corps volunteer in Uganda, and carried that drive into his graduate research, developing novel water treatment technologies and earning an MS in Environmental Chemistry & Technology with a focus on water chemistry at the University of Wisconsin at Madison. Greg’s leadership efforts at CWC are fueled by his desire to make a sustainable improvement in the overall health of watersheds along California’s Central Coast.
Armand Ruby, Technical Director	Armand Ruby has over 30 years of experience as an environmental scientist, specializing in water quality issues. His work has covered surface and ground waters, wastewater and stormwater, as well as atmospheric deposition of pollutants. Armand has worked extensively with municipal agencies throughout California, and facilitated stakeholder working group efforts in several California watersheds. His current and recent work involves source identification for bacteria and other stormwater pollutants, characterization and mitigation of pesticides contamination in urban waterways, toxicity reduction evaluations (TREs), bioassessment monitoring studies, TMDL analysis and implementation, stormwater runoff monitoring program planning and data analysis, and drinking water source assessment. As a consultant for the CA Stormwater Quality Association (CASQA), Armand has negotiated with state regulatory officials, and prepared comment letters for state and federal regulatory proposals, including the statewide Toxicity Policy, Ocean Plan Amendments, DPR’s Surface Water Quality Protection Regulations, and USEPA’s pesticide registration review process. In addition to serving as Principal of Armand Ruby Consulting, Armand also is the chair of the CASQA Monitoring and Science Subcommittee, Monitoring Coordinator for the Regional Monitoring Coalition (RMC) in the San Francisco Bay Area, and Technical Director for the Coastal Watershed Council, and he represents municipal stormwater agencies as a formal member of the California Water Quality Monitoring Council. Armand serves as CWC’s Technical Director as an independent contractor to the organization, not a CWC employee.
