Hawaii Greenhouse Gas Program

For affected sources only:  The deadline for Greenhouse Gas Reduction Plans is June 30, 2015

 

The Department of Health has established the Hawaii Greenhouse Gas (GHG) Program to combat the threat of climate change and sea level rise.  The program utilizes the Air Pollution Control Permit process of the Clean Air Branch to regulate GHG emissions statewide.  The Hawaii GHG program works in conjunction with other Federal and Hawaii State programs to mitigate GHGs.

Background

Act 234 of the 2007 Legislature established the foundation for the Hawaii GHG Program.  It declared a policy to reduce GHG emissions statewide to 1990 levels by 2020.  Parts of Act 234 are codified in Hawaii Revised Statutes, Chapter 342B.

On June 30, 2014, Hawaii Administrative Rules, Chapter 11-60.1 was amended to adopt the new Hawaii GHG program.  The main requirements of the program are set forth in Subchapter 11, Greenhouse Gas Emissions. During promulgation, public comments were solicited and received and a response to comments was provided.

Large Existing Covered Sources

To reduce GHGs, the rules specify a 16% GHG emission cap for large existing stationary sources (“affected sources”) with potential carbon dioxide equivalent (CO2e) emissions at or above 100,000 tons per year.  Each affected source must submit a GHG emission reduction plan for establishing measures that will be used to meet the emission cap.  The approved GHG emission cap and associated monitoring, recordkeeping, and reporting provisions will be made part of the facility’s covered source permit. The deadline for submitting GHG emission reduction plans is June 30, 2015.

See the Instructions for GHG Emission Reduction Plan (PDF).

All Covered Sources

Beginning in 2015, GHG emissions must be included in the calculations to determine annual fees for all facilities holding a covered source permit. Utilize GHG emissions factors and global warming potentials to calculate your CO2e emissions for covered source permit fees.
