(2) A spill containment system shall be maintained for the isolated area under subsection (1) and the spill system shall be impervious and of sufficient size to contain at least 120% of the volume of the largest tank in the isolated area.
7 (1) An antisapstain chemical dip tank shall
(b) if it is an above ground tank, be located in an impervious containment area which has
(ii) a curb that is of sufficient height to enable the containment area to hold at least 120% of the largest chemical dip tank volume, and that prevents entry of surface runoff,
(c) if it is not an above ground tank, be a double wall containment tank constructed with
(i) both walls impervious, and
(ii) a means for determining if there is leakage of the chemicals into the area between the walls,
(d) have an associated impervious primary drip area that provides 30 minutes minimum dripping time for treated wood immediately following the treatment and that prevents entry to the dip tank of surface runoff and precipitation,
(e) have a system for recycling all drippings from the containment area referred to in paragraphs (b) and (c) and from the impervious drip area referred to in paragraph (d) back to the dip tank, and
