(a) By July 1, 2018, a community water system shall compile an inventory of known lead user service lines in use in its distribution system and identify areas that may have lead user service lines in use in its distribution system.
(b) (1) By July 1, 2020, a community water system that has identified known lead user service lines in use in its distribution system as provided in subdivision (a) shall provide a timeline for replacement of known lead user service lines in use in its distribution system to the state board.
(2) By July 1, 2020, a community water system that has identified areas that may have lead user service lines in use in its distribution system as provided for in subdivision (a) shall do both of the following:
(A) Provide to the state board its determination as to whether there are any lead user service lines in use in those areas of its distribution system and provide a timeline to the state board for replacement of those lead user service lines that the community water system has identified.
(B) Provide its findings as to whether there are any areas for which it cannot determine the content of the user service lines and a timeline to the state board for replacement of the user service lines whose content cannot be determined.
(c) The state board shall review and approve a timeline established pursuant to subdivision (b) as follows:

(A) Approve the proposed timeline.
(B) Deny the proposed timeline and propose a revised timeline to the community water system. The state board shall explain to the community water system, in writing, why the community water system’s timeline was not approved, the factors that the state board used to propose a revised timeline, and why the state board used those factors.
(2) If the state board fails to act within 30 days of the submission of the timeline, the timeline shall be deemed approved.
