Revise Subsection R309-500-6(3)(b) to permit public water systems that are eligible for Plan Submittal Waivers based on water line size and system population to request after-the-fact waivers for multiple water line projects by submitting required information about the projects to the Director once a year. Revise Subsection R309-500-6(4)(a)(i) to list the basic information required to be included in the project description of all water line projects for which waivers are requested. This information will be required for individual waivers requested before construction and for multiple-project waivers submitted after construction. Revise Subsection R309-500-6(4) to add a new paragraph (b) to describe the process required for using after-the-fact waivers, including what must be submitted, when it must be submitted, how it must be submitted, and what records must be kept during the year while the projects are being constructed.
