In February of this year, California Assembly Member Tony Mendoza (D-56th Dist; Norwalk) introduced legislation to tighten regulation of aboveground petroleum storage tanks. As summarized by the Legislative Counsel's Digest:
AB 518, as introduced, Mendoza. Hazardous material: aboveground
The Aboveground Petroleum Storage Act requires the State Water
Resources Control Board to adopt a schedule for the inspection of
aboveground storage tank facilities.
This bill would require the schedule to provide, on and after
January 1, 2008, that an inspection be conducted at least once every
two years. The bill would also state an intent of the Legislature to
enact legislation to prohibit the siting of aboveground storage tanks
on lands that are subject to liquefaction.
In March, the bill was referred to State Assembly Committees, form whence the bill hasn't moved. If nothing happens this month, when the deadline for passing legislation in this Session expires, the bill will be dead as a do-do bird (as the old saying goes).
