Updates from the Office of Operator Certification,
State Water Board

Introducing new team members, new initiatives
Provided by Office of Operator Certification, SWRCB, Announcements

Most recently, the Office of Operator Certification (OOC) has made significant changes to the program!

Here are just a few program highlights:


Beginning January 2023, the OOC began the implementation phase of its reorganization to optimize resources and improve processes, workflow, and operational efficiency by balancing staffing resources and realigning workload by functionality as opposed to a programmatic structure. As a result, each OOC unit performs primary functions that include examinations, renewals, and certifications for drinking water and wastewater.

New OOC Staff – Welcome to the Team!

Keisha Kelley, Program Manager
Keisha began her new role in the OOC in May 2023 and brings a wealth of knowledge and leadership experience from her 12 years of working for the State Water Resources Control Board (State Water Board) in various programs. Not only does Keisha bring prior knowledge of the Wastewater Office of Operator Certification Program but she also brings four years of experience developing and implementing a new program, within the State Water Board, as part of the SAFER Program team.

Valerie Gregory, Unit 1 Manager
Valerie began her new role as Unit Manager in March 2023. She has been with the State Water Board since 2000 and with her extensive tenure, primarily in OOC as a Program Analyst, she brings an abundance of knowledge and experience. Valerie played a major role in amending the Wastewater Operator Certification Program regulations adopted in 2013 and has been a pioneer in the creation of the Operator Certification Information System (OCIS) which now houses the online examination applications.
