REQUEST FOR PUBLIC COMMENTS
ON DRAFT AIR PERMIT
REGULATING THE EMISSIONS OF AIR POLLUTANTS
(Docket No. 07-CA-PA-08)
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 PERMIT presently under review for:
Covered Source Permit (CSP) No. 0317-02-C
Initial CSP Application No. 0317-04
Mauna Loa Macadamia Nut Corporation
Mauna Loa Macadamia Nut Plant
Biomass/Oil Fired Boilers and Diesel Engine Generators
Located at: 1 Macadamia Nut Road, Keaau, Hawaii
The DRAFT PERMIT is described as follows:
CSP No. 0317-02-C will grant conditional approval to operate an existing primary boiler fired on biomass (macadamia nut shells) or used oil, a back-up boiler as an additional unit that burns only biomass, and two existing diesel engine generators fired on fuel oil No. 2. The main boiler is equipped with an electrostatic precipitator for controlling particulate emissions. Both the main and back-up boilers are subject to the state particulate emissions limit for biomass boilers requiring emissions not to exceed 0.4 pound of particulate per 100 pounds of biomass burned. Modifications to the facility include an allowance to burn macadamia nut shells continuously in any one boiler. The macadamia nut shell fuel consumption is currently restricted to 12,000 tons per year (TPY). Also proposed, is an increase in the used oil fuel consumption for the main boiler from 270,000 gallons per year to 350,000 gallons per year. This permit, if approved, will supersede Noncovered Source Permit (NSP) No. 0317-01-N, issued on December 20, 2002 under application 0317-02, in its entirety. Changes to the facility will increase emissions as follows:
Pollutant Boiler Emissions (TPY) Significant Level
Biomass Fuel Used Oil Fuel Total Emission (TPY)
Consumption Change Consumption Change Change
SO2 1.2 see note a 8.6 see note b 9.8 40
NOX 17.5 see note c —— 17.5 40
CO 28.1 see note c —— 28.1 100
VOC 0.61 see note c —— 0.61 40
PM 14.2 see note c —— 14.2 25
PM10 10.5 see note c —— 10.5 15
a: Based on remaining capacity to burn macadamia nut shells above the previous 12,000 TPY limit for the main boiler after burning 350,000 gallons per year of used oil.
b: Based on burning 350,000 gallons per year of used oil in the main boiler as worst-case.
c: Based on continuous firing of macadamia nut shells in the main boiler as worst-case.
