Research notes
Hawaii's state-level NEPA analog. Nine statutory triggers under §343-5(a); the most common in development are state/county funds, state/county land use, Conservation district, SMA, and shoreline area. Administered by Office of Environmental Quality Control (OEQC). Procedural — does not directly preempt zoning but creates a parallel approval gate that can effectively block projects. Federal conflict check enabled where also subject to NEPA.
