Current through June 17, 2024
002.01 Facility Planning Requirement. Loan
  applicants will conduct facility planning using the following procedures:
002.01A That projects apply best practicable
  waste treatment technology, which is the cost-effective technology that can
  transport and treat wastewater, separate combined sewers, and remove excessive
  infiltration and inflow in publicly owned Wastewater Treatment Works.
002.01B General Facility Planning
  Requirements. Facility planning will demonstrate 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, the facility plan will demonstrate that 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
  nonmonetary considerations). The facility plan will also demonstrate that the
  selected alternative is implementable from legal, institutional, financial, and
  management standpoints. All facility planning requirements may not be
  applicable to all types of projects. Comprehensive plans or engineering reports
  or studies may fulfill certain facility planning requirements.
002.01C Facility plan contents. A completed
  facility plan is to include:
002.01C1 A
  description of both the proposed Wastewater Treatment Works, and the complete
  Wastewater Treatment Works of which it is a part.
002.01C2 A cost-effectiveness analysis of the
  feasible conventional, innovative, and alternative Wastewater Treatment Works,
  processes and techniques capable of meeting the applicable effluent, water
  quality, and public health requirements over the design life of the facility
  while recognizing environmental and other nonmonetary considerations. The
  planning period for the cost-effectiveness analysis will be at least 20 years.
  The monetary costs to be considered must include the present worth or
  equivalent annual value of all capital costs and operation and maintenance
  costs. A cost-effectiveness analysis shall is to include:
002.01C2.a An evaluation of alternative flow
  reduction methods.
002.01C2.b A
  description of the relationship between the capacity of alternatives and the
  needs to be served, including capacity for future growth expected after the
  Wastewater Treatment Works become operational. This includes estimated flows
  from significant industrial users.
002.01C2.c Cost information on total capital
  costs and annual operation and maintenance costs, including estimated annual or
  monthly costs to residential and industrial users.
002.01C3 A demonstration of the nonexistence
  or possible existence of excessive infiltration/inflow in the sewer system. see
  Chapter 3. 002.01 E.
002.01C4 An
  evaluation of the environmental impacts including ground water and surface
  water impacts of alternatives.
002.01C5 For the selected alternative, a
  concise description at an appropriate level of detail of at least the
  following:
002.01C5.a Relevant design
  parameters;
002.01C5.b Estimated
  capital construction and operation and maintenance costs, and a description of
  the manner in which costs will be financed;
002.01C5.c Cost impacts on Wastewater
  Treatment Works users; and
002.01C5.d Institutional and management
  arrangements necessary for successful implementation.
002.01D Submission and review of a
  facility plan. Each facility plan shall is to be submitted to the Department
  for review.
002.01E
  Infiltration/Inflow.
002.01E1 General. The
  loan applicant is to satisfactorily demonstrate to the Department that each
  sewer system discharging into the proposed Wastewater Treatment Works project
  is not or will not be subject to excessive infiltration/inflow. As an
  alternative loan applicants may propose long term program measures to limit
  infiltration and inflow. For previously existing combined sewers, inflow is not
  considered excessive in any event.
002.01E2 Inflow. If the rainfall induced peak
  inflow rate results or will result in chronic operational problems during storm
  events, or the rainfall induced total flow rate exceeds 275 gpcd (1040 Ipcd)
  during storm events, the loan applicant may perform a study of the sewer system
  to determine the quantity of excessive inflow and to propose a rehabilitation
  program to eliminate the excessive inflow.
002.01E3 Infiltration.
002.01E3.a If the flow rate at the existing
  Wastewater Treatment Works is 120 gpcd (450 Ipcd) or less during periods of
  high groundwater, the loan applicant may build the project including sufficient
  capacity to transport and treat any existing infiltration. However, if the loan
  applicant finds any specific portion of its sewer system is subject to
  excessive infiltration, the loan applicant may document its finding in a
  cost-effectiveness analysis and propose a sewer rehabilitation program to
  eliminate that specific excessive infiltration.
002.01E3.b If the flow rate at the existing
  treatment facility is more than 120 gpcd (450 Ipcd) during periods of high
  groundwater, the loan applicant may perform a study of the sewer system to
  determine the quantity of excessive infiltration and propose a sewer
  rehabilitation program to eliminate the excessive
  infiltration.
