§ 35.2030 Facilities planning.

(a) General. (1) Facilities planning consists of those necessary plans and studies which directly relate to treatment works needed to comply with enforceable requirements of the Act. Facilities planning will investigate the need for proposed facilities. Through a systematic evaluation of alternatives that are feasible in light of the unique demographic, topographic, hydrologic and institutional characteristics of the area, it will demonstrate that, except for innovative and alternative technology under § 35.2032, the selected alternative is cost effective (i.e., is the most economical means of meeting the applicable effluent, water quality and public health requirements over the design life of the facility while recognizing environmental and other non-monetary considerations). For sewered communities with a population of 10,000 or less, consideration must be given to appropriate low cost technologies such as facultative ponds, trickling filters, oxidation ditches, or overland-flow land treatment; and for unsewered portions of communities of 10,000 or less, consideration must be given to onsite systems. The facilities plan will also demonstrate that the selected alternative is implementable from legal, institutional, financial and management standpoints.
