(Docket No. 23-CA-PA-14)

In accordance with 40 Code of Federal Regulations (CFR) §51.102 and Hawaii Administrative Rules §11-60.1-10, the Department of Health, State of Hawaii (DOH) is accepting public comments on the subject draft Regional Haze State Implementation Plan (RH-SIP), Revision 1 for the second implementation period of the U.S. Environmental Protection Agency’s (EPA’s) Regional Haze Rule (RHR).

The proposed Revision 1 to the RH-SIP contains federally enforceable permit limits to address requirements of the RHR to 1) improve visibility on the most impaired days and 2) ensure no visibility degradation occurs on the clearest days for each Class I area in the state (Haleakala National Park on Maui Island and Hawaii Volcanoes National Park on Hawaii Island). These goals and long-term strategies for achieving the goals are included in RH-SIPs covering each ten-year (10-year) period up to 2064. Hawaii has committed to implement its long-term strategy to improve visibility including fuel switching to ultralow sulfur diesel, addon air pollution controls, and other requirements to shut down units within and outside of this second regional haze planning period. Pursuant to 40 CFR §51.308(f) of the RHR, Hawaii’s RH-SIP includes the following key elements:

Calculations of baseline, current, and natural visibility conditions; progress to date; and the uniform rate of progress for each Class I area – Chapter 3;
Statewide emission inventories of visibility impairing pollutants – Chapter 4;
Source screening including an analysis with Q/d, a more sophisticated weighted emissions potential/ area of influence (WEP/AOI) analysis, and supplemental analysis – Chapter 5;
Source specific four-factor analyses of facilities screened – Chapters 6 and 7;
Long-term strategy for regional haze including federally enforceable emission limitations and compliance schedules – Chapter 7 and Appendix P with draft permits;
Reasonable progress goals based on the regional haze controls selected – Chapter 8;
A progress report addressing the requirements of 40 CFR §51.308(g)(1) through (5) – Chapter 9;
Monitoring strategy and other implementation plan requirements – Chapter 9; and
Documentation of consultation with EPA, Federal Land Managers (FLMs), and the regulated industry – Chapter 9.

Based on the four-factor analyses, WEP/AOI rankings, and source retirement commitments in place of controls selected from the four-factor analyses, the following regional federally enforceable conditions were established in permits for five facilities:

Hawaii Island Sources:
Kanoelehua-Hill Power Plant – Permanent shut down of Boilers Hill 5 and Hill 6 by the end of 2028.

Puna Power Plant – Fuel switch from fuel oil No. 6 to ULSD for the plant’s boiler by four (4) years from permit issuance. The permit was issued on August 10, 2022, for the boiler fuel switch.

Mauna Loa Macadamia Nut Corporation Plant – Permanent shut down of main boiler by the end of 2026. The main boiler will be replaced with another unit after shut down of the existing unit.

Maui Island Sources:
Kahului Power Plant – Permanent shut down of Boilers K-1, K-2, K-3, and K-4 by the end of 2028.

Maalaea Power Plant:

o Fuel injection timing retard for Diesel Engine Generators M1 and M3 by the end of 2027.
o On and after December 31, 2027, M7 and M10-M13 must not operate without selective catalytic reduction (SCR) installed or permanently shut down by end of:

2037 for M7;
2030 for M10 and/or M11;
2032 for M10 or M11 if one of these units is shut down by the end of 2030 or installs SCR; and
2037 for M12 and M13.
