### Source performance testing was conducted on two oil-fired boilers used to generate electrical power while firing 2% sulfur industrial fuel oil. These boilers, designated as Units H-5 and H-6, are in service at the Kanoelehua-Hill Generating Station (HGS) in Hilo, Hawaii. The Hawaii Electric Light Company (HELCO) owns and operates this facility. The Hawaiian Electric Company, Inc (HECO) coordinated the testing for this emissions project. TRC - Air Measurements, Gainesville Office (TRC) conducted these tests on August 26" through 28~, 2010. The purpose of this testing was to conduct testing in advance to meet the requirements for regional haze emissions testing. These sources operate accordingto requirements set forthby the Hawaii Department ofHealth (HDOH) Covered Source PermitNo. 0234-01-C. The testing was conducted on each unit while operating at full load. The tests followed the procedures set forth in the Code ofFederal Regulations, Title 40, Part 60 (40 CFR 60), Appendix A, 

### Methods 1, 2, 3A,4,5,6C,7E, 9, 10, 19,25A ,202, and The US EPA Other Test Method (0TM)-027.

Exhaust emissions were analyzed from the boiler stacks for oxides of nitrogen (NOx), sulfur dioxide (SO*), carbon monoxide (CO), total hydrocarbon compounds (THC) as volatile organic compounds (VOC), oxygen (02), and carbon dioxide (CO*) using continuous instrumental monitors. Particulate matter (PM) samples for total particulate, PMlo,and PM2.5, including condensable particulate, were collected isokinetically fiom the boiler stack using a combined hotlcold manual sampling train. Visible emissions tests were also conducted during these tests. HECO Environmental Chemistry Laboratory of Honolulu, Hawaii analyzed fuel samples for total sulfur content, per the American Society of Testing and Materials (ASTM) Method D4294 and gross heating value per ASTM Method D240.

### The Kanoelehua-Hill Generating Station is located in Hilo, Hawaii.Process Description:

Regulatory Application:

Emission Sampling Points:

Test Methods: Unit H-5 is a 14.1-MW Combustion Engineering Model VU-60 oil-fired boiler used to produce steam for generation of electrical power distributed on the local grid. The boiler is fired with industrial fuel oil that has a sulfur content not to exceed 2.0%.

Unit H-6 is a 23-MW Combustion Engineering Model VU60 oil-fired boiler used to produce steam for generation of electrical power distributed on the local grid. The boiler is fired with industrial fuel oil that has a sulfur content not to exceed 2.0%. Hawaii Department of Health Covered Source Permit No. 0234-0l-C regulates the operation ofthese sources.
The Unit 5 stack was a 130ft tall stack with an approximate 1.2degree taper. The stack inside diameter was 55 inches at the test ports elevation. The two test ports were located approximately 64' downstream from where the top of the duct entered from the side and approximately 25' upstream of the stack outlet. Flow rate calculations for the tapered stack followed EPA guidelines.

The Unit 6 test location was in a horizontal duct with a rectangular cross-section measuring 53.5-inches deep by 101.5-inches high. The five vertical test ports were located 21'2" downstream from a bend and 54" upstream from the vertical stack.

EPA Method 1 was used to select particulate matter (PM) sampling point locations.

EPA Method 2 was used to measure stack gas differential pressures, i.e., velocity measurements. These measurements
were used for verification of sampling isokinetics, calculation of stack gas flow rates, and determination of
mass pollutant emission rates.

EPA Method 3A was used to determine oxygen (02) and carbon dioxide (CO2)concentrations.

EPA Method 4 was used for determination of stack gas moisture content.

EPA Methods 5 and 202 were used for determination of total PM (filterable and condensable) concentrations.Test Methods (Continued): EPA Method 6C was used for determination of sulfur dioxide (SO2)concentrations

EPA Method 7E was used for determination of nitrogen oxides (NOx)concentrations

EPA Method 9 was used to determine opacity using visible emissions (VE) measurements by a certified observer.

EPA Method 10 was used for determination of carbon monoxide (CO)concentrations.

EPA Method 19 was used for determination of pollutant emission rates using published fuel factors.

EPA Method 25A was used for determination of total hydrocarbon compound (THC)concentrations used to report volatile organic compound (VOC) concentrations.

other Test Method (OTM) 027 and EPA Method 202 were used for determination of PM25 and PMloconcentrations (filterable and condensable). American Society ofTesting and Materials (ASTM)Method D4294 was used to determine sulfur content in the fuel oil by x-ray diffraction.

ASTM Method D240 was used to determine the heating value ofthe fuel oil by bomb calorimeter.

### SUMMARY 

### OFRESULTS

The Hawaii Electric Light Company, Inc. (HELCO) owns and operatesthe KanoelehuaHill Generating Station (HGS) in Hilo, Hawaii. Among the units at this facility, two oil-fired boilers are used to produce steam for generation of electrical power while firing industrial fuel oil that has a sulfur content not to exceed

Table 2 provides the Executive Summary of the Units H-5 and H-6 regional haze emissions test results. The emissions test results are an average of the three test runs at the full load for each boiler. NOx, CO, VOC, and SO2 emissions concentrations are reported in units of parts per million by volume (ppmv) on a dry basis corrected to 

### 3% excess 02. Concentrations of PM were reported in terms of grains ofparticulate per dry standard cubic foot (grtdscf)corrected to 12% excess CO2. Emission rates for NOx, SO2, CO, VOC, and PM are reported in terms of pounds per million British thermal units of fuel burned (IbstMMBtu) and pounds per hour (Ibsthr). Fuel sulfur content is reported on a percent weight basis (% wt).

0.13Stratification within the stack was evaluated prior to testing using a three-point traverse. The stratification was minimal (less than 5%) forNOx, S02,and C02 emissions. All subsequent sampling was conducted from a single point of average emissions during each test run. Each test
run for the gaseous parameters NOx, SO2,CO, VOC, 02, and CO2 was 60 minutes in duration. The total particulate matter test runs, including both filterable and condensable particulate, were also 60 minutes in duration. Test runs for PMloand PM25 were conducted using a combined sampling train that collected both sample fractions along with the condensable particulate fraction. These runs were 90 minutes in duration. Moisture and velocity measurements were conducted in conjunction with the PM sampling. Visible emissions (VE) testing consisted of three 6-minute test runs, conducted three times for each boiler. Both TRC and HELCO personnel were used to conduct the various VE tests. Fuel samples were collected during each day oftesting and analyzed for sulfur content and gross heating value.

Tables 3 and

These tabular summaries contain all pertinent operational parameters, ambient conditions, measured emissions, corrected concentrations,and calculated emission rates. NOx, SO2, and CO emissions are reported in units of ppmv on a dry basis, corrected to 3% 02. Volatile organic compound (VOC) concentrations were determined from THC measurements and were determined on a ppmv, wet basis as methane, reported also on a ppmv, dry basis as methane, corrected to 3% 02. Concentrations of PM were determined in units of grams of PMIDSCF and reported in terms of grains PMIDSCF at 12% excess C02. Emission rates for NOx, S02,CO, PM, and VOC are reported in terms of IbsIMMBtu and Ibslhr.

Volumetric flow and mass emission rates were determined using the EPA Method 1 through
