Concerning membership in the public employees' retirement system for port workers who participate in a federal railroad retirement plan, a union-sponsored defined benefit retirement plan, or another employer-funded private pension plan.

Added a new finding that the legislature intends to resolve ambiguity about a port district's authority to contribute to private Taft-Hartley pension plans, exempting employees covered by such plans since January 1, 1965.

Modified the eligibility criteria for port workers in federal railroad retirement plans to specify that they are ineligible for the state system for any period the district pays payroll taxes toward their federal benefits.

Removed a specific provision for part-time bus drivers serving naval shipyards who are simultaneously employed by the federal government, as this was likely subsumed by the broader federal retirement system exemption.

Consolidated and renumbered the list of ineligible employees, merging the separate clauses for railroad and union-sponsored plans into distinct subsections for clarity.
