ATCP 33.38(1)(d) (d) The walls and floors of a sump shall be at least as thick, at every point, as the mixing and loading pad or secondary containment structure floor that drains to the sump.

ATCP 33.38(1)(e) (e) A sump that is part of a mixing or loading pad shall form part of a continuous surface, having an area of at least 15 feet by 15 feet and a capacity of at least 250 gallons, which is free of construction and control joints.

ATCP 33.38(1)(f) (f) If a sump is constructed as part of a concrete mixing and loading pad or concrete secondary containment structure, it shall be constructed in a continuous concrete pour with that pad or structure.

ATCP 33.38(1)(g) (g) No pipes or openings may extend through a sump. This does not prohibit a surface trough or rim indentation needed to accommodate a pipe or hose connection required under s. ATCP 33.50.
