Shelley lagoons at capacity Violate their NPDES permit Shelley initiated evaluation Shelley informally vetted regionalization January 2000 – Invitations extended to participate August Committee formed to apply for grant funds

Participating Entities Cities – Ammon & Shelley Cities – Firth & Basalt District – IBSD Counties – Bingham & Bonneville Private – Melaleuca, AndCo, Basic American Facilities Planning Study Evaluate feasibility of wastewater treatment on a regional basis Determine cost to end user

Manage high growth in counties, Provide geographical alternatives for economical development Develop long-range planning tool to better protect the ground and surface water resources Reuse of effluent integral to water conservation, Increase reliability of compliance Eliminate political barriers Increase environmental protection for each participating entity as well as non-participating entities in the surrounding region

Regional System was Feasible One Treatment Plant in Shelley Transmission Lines from: Ammon Basalt/Firth Exit 113 Industrial Pretreatment Cost per user ~ $36/month

Develop a funding package Adequate to meet expenses Proportional to each entity Fair to the individual customer Acceptable to the patrons Organize a formal entity Combined resources Preserved community identity Facilitated management of the system Overcome the loss of one partner

2004 JPA developed EIRWWA officially formed Revised FPS submitted to DEQ IBSD formally withdrew EPS grant secured from EPA for preliminary design tasks 2005 DEQ approval of FPS 2006 ACOE money authorized for project
