Amends and adds to existing law to provide that plats shall show certain pipelines, to require filing of certain information with counties, and to require certain notice regarding zoning ordinance changes and development proposals.

This bill clarifies roles and responsibilities when there is a proposed development near an interstate natural gas or petroleum transmission pipeline. There are only four such interstate pipelines in Idaho, but they predate the state's population growth. At the time each of them was constructed, they were in rural areas. Since that time, population growth means that developments are much closer than was ever anticipated. So the bill incorporates interstate transmission pipelines into existing planning and zoning processes to ensure that all paries work together from the outset of the process. It creates a shared responsibility between the pipeline company, the local government and developer to make sure the three parties have common information about future development, safety protocols and needs for clarification.
