Water resources: demands: data centers.

Impact

AB 93 significantly impacts state law by asserting that water conservation is a matter of statewide importance, thereby limiting local jurisdictions' autonomy to dictate their regulations on water use. It establishes requirements that data centers must meet efficiency standards set by local governments, potentially changing how local authorities approach water usage planning and enforcement. The requirement for data centers to provide water consumption data and meet efficiency guidelines fosters increased accountability and could lead to enhanced conservation efforts throughout California's urban regions.

Summary

Assembly Bill 93, introduced by Assembly Member Papan, focuses on the increasing water demands posed by data centers in California. The bill mandates that data center operators must submit both an expected water use estimate when applying for their initial business license and a report of annual water use for the renewal of that license. This process, which requires self-certification under penalty of perjury, aims to ensure that local jurisdictions can adequately manage and monitor water consumption from these substantial users. The bill addresses ongoing concerns regarding the sustainability of water resources amidst growing technological needs in the state.

Sentiment

The sentiment surrounding AB 93 appears to be largely supportive among proponents of water conservation and sustainable infrastructure. Legislators and environmental groups advocating for this bill argue that it is a necessary step toward responsible resource management in the face of escalating technology demands. However, there may be concerns among business stakeholders regarding the potential increased regulatory burden and operational costs associated with meeting the new requirements. The discussion indicates a balance between economic development and environmental stewardship.

Contention

Notable points of contention arise from the bill's implications for local governance versus state oversight. The move to mandate specific water usage estimates and efficiency stipulations can be viewed as an overreach by the state government, potentially leading to resistance from local authorities who prefer to maintain control over their water regulation policies. Critics argue that a one-size-fits-all approach may not adequately address the unique needs and challenges faced by different areas, especially those with varying water availability and infrastructure capacities. This highlights ongoing tensions between developing technology and managing scarce resources.
