The Office of Environmental Quality Control (OEQC) facilitates Hawaiʻi’s environmental review process. The office announces the availability of environmental assessments (EAs) and environmental impact statements (EISs) for public review and comment in its semi-monthly publication, The Environmental Notice. OEQC staff also review and comment on these documents and provide assistance throughout the environmental review process.

Hawaiʻi Environmental Review Web Map

This web map shows Hawaiʻi State environmental review actions (EAs, EISs, acceptance and supplemental determinations, and withdrawals) published from 11/23/2015 through 10/23/2017, and includes some older actions as well. Click on the double arrow on the top left to turn different map layers on or off, and click the arrow next to the Environmental review actions layer to view the legend for that layer.

Click the left and right arrows at the top of the pop-up window to view multiple actions that share the same project area (e.g. Draft and Final EAs or EISs for the same project area). The map will be improved as time permits.

Agencies may declare minor or routine actions proposed by themselves or applicants that trigger Hawaiʻi environmental review exempt from the process. There are two ways agencies can exempt actions: (1) by showing that type of action is on their Environmental Council-concurred exemption list (this is the most straightforward way), or (2) if that type of action is not on their exemption list, showing that it falls within one of the 11 exempt classes of action and getting advice from other agencies or individuals with jurisdiction or expertise on the exemption, per HAR § 11-200-8(a).
