The California State Water Resources Control Board (State Water Board) recently issued a revised draft State Policy for Water Quality Control for Standardized Cost Reporting in Municipal Separate Storm Sewer Systems (MS4) Permits (the Policy). If adopted, this Policy would require permittees subject to MS4 permits to use a list of standardized cost categories to track and report their MS4 permit implementation costs.

The State Water Board released the revised draft Policy on May 9, 2024 for a second round of public comments, which will be due on June 25, 2024, and will hold a public hearing on June 4, 2024. Once the Policy is adopted by the board and approved by the Office of Administrative Law, it would require the regional water boards to incorporate the new cost reporting requirements when they next amend or renew Phase I MS4 permits.

Court Finds ‘Occurrence’ Language Ambiguous, Reviving Church’s Coverage Claim For Abuse Settlement

A Tenth Circuit decision examines whether a church's alleged failure to prevent multiple instances of sexual abuse by one perpetrator constitutes a single insurance "occurrence" or multiple occurrences, with significant implications for coverage limits and settlement aggregation.
