Safety and Physical Security Previous Policy Topics Presented 3 4 3/17/2021 3 5 Budget Controls and Fiscal Discipline Policy Statement: OC San will prudently manage the public funds that it collects. It will take a long‐term planning approach to its facilities and rate setting that provides a stable setting program, prudent reserves, and pay‐as‐you‐ go philosophy for operating and replacing capital expenses. 6 Policy Statement: OC San must maintain adequate cybersecurity (information technology security) techniques that protect computer assets, networks, programs, data, and industrial control equipment from unauthorized access or attacks that are aimed for exploitation. Cybersecurity 5 6 3/17/2021 4 7 Policy Statement: OC San owns and operates assets throughout its service area located in property owned in fee, through easements and in the public right‐of‐ way. The Sanitation District will identify and protect all of its property rights to assure that its assets are not encumbered or encroached upon so that the facilities may be properly operated, maintained, upgraded, and replaced. Property Management 8 Policy Statement: OC San will attract and retain high quality talent to support its mission and continue to be an industry leader. It will safeguard leadership continuity and support effective performance of the organization by proactively monitoring the changing work environment and requirements to ensure development programs are relevant and build a skilled bench of readily available successors for key leadership and mission‐critical positions. Resilient Staffing 7 8 3/17/2021 5 9 Policy Statement: OC San will ensure the safety and security of employees, contractors, and visitors through standard practices, policies, and procedures that support a safe and secure environment, provide an appropriate level of security, and safeguard OC San’s property and physical assets.

These commodity chemicals are provided by outside vendors through the purchasing process. OC San will identify chemicals key to its operation, investigate the market risks for those chemicals and devise strategies to mitigate identified risks to availability and pricing. Policy Statement 78 77 78 3/17/2021 40 •OC San has adopted a policy to support multiple vendors to maintain competition in the market. This is the basis for recommending multiple contracts to supply the same chemical. Short‐term vs. Long‐term Costs This strategy may be more costly in the short‐term but provides long‐term savings and source reliability. •Initiative: Reduce reliance on particular chemicals and Individual vendors and establish flexibility to utilize other chemicals/processes to accomplish the same operational objectives.
