Environmental protection: underground storage tanks; underground storage tank corrective action fund; modify. Amends secs. 21502, 21503, 21506a, 21506b, 21510, 21510a, 21510d, 21515, 21516, 21518, 21519, 21519a, 21521, 21524 & 21548 of 1994 PA 451 (MCL 324.21502 et seq.) & repeals sec. 21510c of 1994 PA 451 (MCL 324.21510c).
HB 4940 updates Michigan's rules for managing funds used to clean up leaks from underground storage tanks, primarily affecting gas station owners and other tank operators. The bill modifies specific sections of the 1994 environmental law to adjust how corrective action funds are administered, including reporting requirements and fund allocation procedures. It also repeals an outdated section (21510c) related to the fund. These changes aim to streamline the cleanup process without altering the core environmental protections for tank sites.

MINOR
The bill text was updated from a preliminary version to a revised substitute, incorporating specific amendments to the Natural Resources and Environmental Protection Act. These changes refine the definitions of key terms like 'bulk transfer' and 'claim,' adjust liability limits for underground storage tank releases based on the number of tanks owned, and correct grammatical errors in the definitions of 'claim' and 'claim limit.' The updates aim to clarify the legal framework for environmental cleanup funding and liability.
Scope change
The scope of liability for claims under the Underground Storage Tank Act is now explicitly tiered based on the number of tanks owned by the operator (1-100 tanks vs. more than 100 tanks), with corresponding adjustments to the maximum claim limit.
DEFINITION
The definition of 'bulk transfer' was expanded to explicitly include pipeline and marine vessel movements of refined petroleum, clarifying what constitutes a transfer within the bulk terminal system.
ELIGIBILITY
The definition of 'claim limit' was revised to establish two distinct tiers: $1,000,000 for owners of 1 to 100 tanks and $2,000,000 for owners of more than 100 tanks.
TECHNICAL
Several grammatical errors and formatting inconsistencies were corrected in the definitions of 'claim,' 'claim limit,' and 'claim period' to ensure legal clarity.
