REQUEST FOR PUBLIC COMMENTS
ON DRAFT AIR PERMITS
REGULATING THE EMISSIONS OF AIR POLLUTANTS
(Docket No. 22-CA-PA-09)
Pursuant to Hawaii Revised Statutes (HRS), Chapter 342B-13, and Hawaii Administrative Rules (HAR), Chapter 11-60.1, the Department of Health, State of Hawaii (DOH), is requesting public comments on the following DRAFT PERMITS presently under review for:
(1) Amendment of Covered Source Permit (CSP) No. 0232-01-C
Maui Electric Company, Ltd.
Kahului Generating Station
Located At: 200 Hobron Avenue, Kahului, Maui
(2) Amendment of Covered Source Permit (CSP) No. 0234-01-C
Hawaii Electric Light Company, Inc.
Kanoelehua-Hill Generating Station
Located At: 54 Halekauila Street, Hilo, Hawaii
(3) Amendment of Covered Source Permit (CSP) No. 0235-01-C
Hawaii Electric Light Company, Inc.
Puna Generating Station
Located At: Puna Mill Road, Keaau, Hawaii
The DRAFT PERMITS are described as follows:
The permit amendments incorporate federally enforceable regional haze control measures in accordance with HAR §11-60.1-10(a)(2) and (a)(3), Clean Air Act §169A(g)(1), and the Environmental Protection Agency’s Regional Haze Rule. The control measures reduce maximum potential to emit (PTE) of pollutants that impair visibility; namely sulfur dioxide (SO2), nitrogen oxides (NOX), and particulate matter (PM). Maximum PTE is also reduced for carbon monoxide (CO), volatile organic compounds (VOCs), and greenhouse gas/carbon dioxide equivalent (CO2e) emissions as a co-benefit.
(1) The significant modification of CSP No. 0232-01-C incorporates an enforceable commitment to retire all boilers (K-1, K-2, K-3, and K-4) at the Kahului Generating Station by December 31, 2027. The following is the maximum PTE for this facility before and after the boilers are retired:
Pollutant Maximum PTE Maximum PTE
Before Boilers are Shut Down After Boilers are Shut Down
(TPY) (TPY)
CO 157 0
NOX 1,472 0
SO2 5,219 0
VOC 11 0
PM 1,527 0
CO2e 386,882 0
(2) The significant modification of CSP No. 0234-01-C incorporates an enforceable commitment to retire Boilers Hill 5 and Hill 6 at the Kanoelehua-Hill Generating Station by December 31, 2027. The following is the maximum PTE for this facility before and after the boilers are retired:
Pollutant Maximum PTE Maximum PTE
Before Hill 5 and Hill 6 Shutdown After Hill 5 and Hill 6 Shutdown
(TPY) (TPY)
CO 433 304
NOX 3,556 2,434
SO2 3,872 322
VOC 139 119
PM 800 108
CO2e 528,542 204,020
(3) The significant modification of CSP No. 0235-01-C incorporates an enforceable commitment to implement a fuel switch for the Puna Boiler to only ultra-low sulfur diesel (ULSD) with 0.0015% maximum sulfur content by four years from permit issuance for reducing sulfur dioxide (SO2), nitrogen oxide (NOx), and particulate matter less than ten microns (PM10). The permit amendment also carries over existing regional haze permit provisions to cap sulfur dioxide (SO2) emissions. The cap limits the sum of total SO2 emissions from the Puna Generating Station Boiler and Boilers Hill 5 and Hill 6 at the Kanoelehua-Hill Generating Station to 3,550 tons per year. The following is the maximum PTE for the Puna Generating Station before and after the fuel switch:
Pollutant Maximum PTE Maximum PTE
Before Fuel Switch After Fuel Switch
(TPY) (TPY)
CO 2,156 2,156
NOX 1,025 375
SO2 2,882 484
VOC 1,314 1,314
PM 399 102
CO2e 378,397 376,997
