Section 323.2219. Evaluation of feasibility of alternatives to discharge to groundwater.

Rule 2219.(1) An  evaluation   of  the  feasibility  of   alternatives  to discharge to the groundwater required by R 323.2218(3)(a)(ii) shall contain, at a minimum, an analysis of the feasibility of items contained in this rule. Feasibility includes the practical ability to implement the alternative and a comparison of the cost of the alternative to its benefits.

(2)        At a minimum, alternatives to the discharge that shall be considered are minimizing the volume and toxicity of the wastewater, recycling wastewater, connecting to a municipal sanitary sewer system, and discharging to surface water. Alternatives for minimizing the volume and toxicity of wastewater include pollution prevention   opportunities,   including  the following:

(a)     Equipment or technology modifications.

(b)     Process or procedure modifications.

(c)     )  Reformulation or redesign of products.

(d)    Substitution of raw materials.

(e)     Improvements in housekeeping, maintenance, training, or inventory control.

(3)         At a minimum, the following treatment systems shall be considered for substances determined to be in the discharge by the characterization required by R 323.2220:

(a)      For a metal, the following:

(i)       Flocculation.

(ii)     Settling.

(iii)   Oxidation.

(iv)     Filtration.

(v)       Ion exchange

(vi)     Reverse osmosis.

(vii)   Electrolytic recovery.

(b)       For a volatile substance, the following:

(i)       Carbon adsorption.

(ii)     Air stripping.

(iii)   Aeration.

(c)       For a nonvolatile substance, the following:

(i)       Sorption.

(ii)     Settling.

(iii)   Filtration.

(d)         For a substance that degrades biologically, biological treatment in a lagoon, tank, or biological reactor or through controlled land treatment.
