[DeTomaso] California engine swap exemption question

[John Buckman]

Bud,

In 1961, the first automotive emissions control technology in the nation, Positive Crankcase Ventilation, was mandated by
the California Motor Vehicle State Bureau of Air Sanitation to control hydrocarbon crankcase emissions.

In 1963, the Positive Crankcase Ventilation requirement of 1961 went into effect on domestic vehicles for sale in California.

In 1966, auto tailpipe emission standards for HC and CO were adopted by the California Motor Vehicle Pollution Control Board.
It was the first of their kind in the nation.

In 1967, the California Air Resources Board (ARB, later to become CARB) was created from the merging of the California Motor Vehicle Pollution
Control Board and the Bureau of Air Sanitation and its Laboratory.

In 1969, Air Quality Standards were set by the new ARB (Air Resources Board) for total suspended particulates, photochemical
oxidants, sulfur dioxide, nitrogen dioxide, and carbon monoxide.

In summary, the PCV requirement went into effect in California in 1963.
