“Used oil” means used oil, as defined in subdivision (a) of Section 25250.1 of the Health and Safety Code. Used oil does not include articles contaminated with de minimis quantities of used oil, such as used oil filters, oily rags, and scrap metal.
The legislature occasionally skips outline levels.
For example:
(3) A person may apply [...]
(4)(a) A person petitioning for relief [...]
In this example, (3), (4),
and (4)(a) are all outline levels, but
(4) was
omitted by its authors. It's only implied. This presents an
interesting challenge when laying out the text. We've
decided to display a blank section with this note, in order
to aide readability.
