capacity; (ii) requirements for a permeable interface between chamber and
bundled expanded polystyrene effluent distribution systems and trench sidewall
soil surfaces for the absorption of wastewater; (iii) criteria for the allowable
slope, maximum length, minimum sidewall depth, and minimum lateral separation of
chamber and bundled expanded polystyrene effluent distribution system absorption
trenches; (iv) criteria for substituting chamber and bundled expanded
polystyrene effluent distribution systems for gravity percolation trenches and
gravel and crushed stone low pressure systems; (v) criteria for determining the
minimum area requirements for chamber and bundled expanded polystyrene effluent
distribution system absorption trenches; and (vi) such other requirements
