MODERATE

This bill version updates administrative details and clarifies the composition of the Cesspool Conversion Implementation Working Group. It changes the bill's status from House Draft 2 to Senate Draft 1, updates the responsible staff member, and adjusts the working group membership rules to give the Department of Health discretion over the number of private individual members while maintaining the requirement for county and nonprofit representation.

Scope change

The bill's substantive scope regarding cesspool mandates and funding remains unchanged; however, the working group's membership criteria were modified to allow the Department of Health to determine the maximum number of private individual members.

TECHNICAL

Updated bill metadata including the version (HB1730 SD1), responsible staff (Margaret McGary), and revision numbers to reflect the transition from the House to the Senate.

Updated the report title to pluralize 'Appropriation' to 'Appropriations' and changed the version tag from (HD2) to (SD1).

REQUIREMENT

Clarified that the working group member must be selected by the Hawaii State Association of Counties, rather than just being a county official selected by them.

Changed the description of nonprofit members from 'non-profit groups' to 'nonprofit groups' for consistency.

Added a provision granting the Director of Health discretion to determine the maximum number of private individuals who can serve as working group members.
