The county of Marin is declared to be a nuclear-free zone.

(a) No person shall knowingly engage in any activity within the county, the purpose of which is the applied research, development, production, transport, deployment, launching, testing, maintenance or storage of nuclear weapons or components of nuclear weapons. Nor shall any person store, use, transport, or dispose of special nuclear material or nuclear waste within the jurisdiction of the county.

(1) As to roadways which are within the exclusive jurisdiction of the county, transportation of such materials is prohibited,

(2) As to roadways which are demonstrably within the jurisdiction of the state or federal government, the county board of supervisors shall post as a regular monthly notice, once each month, in a newspaper of general circulation within the county the fullest description possible of any shipment of such material that has occurred that previous month, transported through or across the county by any means of transportation whatsoever.

(d) The county board of supervisors shall adopt a "peace conversion plan," and shall, within ninety days of the enactment of this chapter, establish a county peace conversion commission of not less than three or more than five members, which shall be comprised of volunteers from the community.

Said commission shall:

(1) Conduct studies of existing county contracts and public fund investments with nuclear weapons contractors, and determine in which cases any reasonable alternative contract or investment exists, in a manner consistent with prudent investment policy, and mindful of the intent and purpose of this chapter.

The commission will be responsible for conducting a timely phase-out of nuclear weapons contractors from the county, and for insuring the smooth conversion of Marin County businesses to alternative work that is more consistent with the public welfare. For this purpose the commission shall solicit testimony from the public.
