Water resources: data centers.

Impact

The provisions introduced by AB 93 affect the Business and Professions Code by specifically addressing water supply obligations for data centers. By categorizing data centers as significant users of water, the bill seeks to implement greater oversight over their water consumption practices, thereby aligning with the state's conservation goals. This will likely necessitate changes in how data centers operate and report their water usage, ensuring compliance with any efficiency guidelines set forth by the Department of Water Resources.

Summary

Assembly Bill 93, introduced by Assembly Member Papan, aims to regulate water use by data centers in California. The bill requires data center operators to provide estimates of expected water use to their water suppliers before applying for or renewing business licenses. This mandates self-certification under penalty of perjury, essentially expanding accountability around water consumption in an effort to promote conservation and sustainable usage of water resources.

Sentiment

The sentiment regarding AB 93 appears supportive from environmental advocacy groups, as it addresses water conservation—a pressing issue in California. However, concerns may arise from the data center industry regarding the potential administrative burden of additional reporting and self-certifications, as well as implications for future business operations. As the bill enforces stringent requirements, reactions may vary based on stakeholder interests in balancing economic growth and environmental stewardship.

Contention

Notable contention points surrounding AB 93 might involve discussions on the feasibility and effectiveness of self-certification processes versus traditional oversight. Industry stakeholders could argue that the cost of compliance may be high, especially for smaller data centers. Conversely, proponents may argue that proactive measures, such as those in AB 93, are necessary for long-term sustainable water management in a state facing severe water scarcity.
