Underground Safety Board Rulemaking
The Dig Safe Act of 2016 created the California Underground Facilities Safe Excavation Board to enforce Government Code 4216. It directed the Board to create rules and regulations where none currently exist to improve worker and public safety across the state. Under California law, the rulemaking process ensures that all stakeholder and community voices are heard and that all viable options for action have been considered. Only after prescribed periods of public notice and public input is a measure adopted. To ensure that the adopted regulation meets the original directives of California’s legislature, an independent review by the Office of Administrative Law is undertaken before the regulation can take effect.
