### Chapter 1: Background Section 169A of the Clean Air Act requires sources affecting areas designated as Class I areas to reduce emissions to eliminate all anthropogenic obscuration of visibility, with the goal of reaching natural background levels of visibility by 2064. The U.S. Environmental Protection Agency (EPA) requires a State Implementation Plan or a Federal Implementation Plan that describes the level of visibility resulting from natural impairment and how much anthropogenic sources need to be reduced in the first ten years (by 2018) to keep the area on track to attain the goal of reaching natural background levels by 2064. Virgin Islands National Park, on St. John in the United States Territory of the Virgin Islands (USVI), is a Class I area where visibility of the national park is to be protected. Thus, the Virgin Islands National Park is required to develop a plan to reduce emissions to improve visibility over the ten year period ending 2018. Emissions from sources on St. John and other nearby islands in the region, may be contributing to visibility impairment in the Virgin Islands National Park. The purpose of this study is to perform a sensitivity study and determine what type of emissions and amounts would have a visibility impact on the Class I area.Mr. Robert Kelley March 31, 2011

### Chapter 2: Model Setup 2.1 Site Description The Virgin Islands National Park covers approximately 60% of St. John located in the United States Virgin Islands. The park also contains Hassel Island, a small island located in Charlotte Amalie Harbor of

St. Thomas. St. John is home to 4,197 persons, according to the 2000 United States Census Bureau data. This represents just under than 4% of the total population of the USVI. St. John is less than 5 kilometers from two more populated islands, the USVI of St. Thomas to the West, and the British Virgin Island (BVI) to the Northeast. There are many other islands within the modeling domain, including St. Croix approximately 60 km to the South, and Puerto Rico about 90 km to the West. Figure 1 presents the Caribbean Basin and approximate modeling domain. Figure 2 presents the park boundaries and nearby islands.

### 2.2 Meteorological Data MACTEC obtained and applied the necessary meteorological data for use in CALPUFF for the project area. MACTEC used data from the period 2007 through 2010 as those were the only years with National Data Buoy Center (NDBC) data available. Discussion of MACTEC’s examination of and subsequent decision to use NDBC data is documented in Appendix A. The meteorological data used was from two National Weather Service stations. The upper air data was from San Juan L M Marin Airport (WBAN 11641) in San Juan, Puerto Rico, which is the closest upper air station to the Virgin Islands National Park. The hourly surface weather data was from Charlotte Amalie Airport (WBAN 11640) in Charlotte Amalie, St. Thomas, which is the closest surface meteorology station to the Virgin Islands National Park. Overwater buoy data from between 2 and 5 NDBC stations was used for each year of CALMET data processing, depending on availability (Table 1 in Tables section of report). The hourly surface data is required by CALMET in one of two formats: Solar and Meteorological Surface Observation Network (SAMSON) or Hourly US Weather Observations (HUSWO). These data sets contain data for 1961-1990 and 1990-1995, respectively. More recent data are stored in the Integrated Surface Hourly (ISH) format available from the National Climatic Data Center (NCDC). TheMr. Robert Kelley March 31, 2011

### data can be requested or retrieved from CD ineither ISH-abbreviated or ISH-floating format. Since the ISH format is not processed by the version of CALMET available through the EPA Support Center for Regulatory Atmospheric Modeling (SCRAM) web site, the data were retrieved in the ISH floating format and converted to the SAMSON format using the program NCDC_CNV (http://www.rflee.com/RFL_Pages/Meteor.html). The mixing height data was compiled using the Mixing Height Program taken from the EPA’s SCRAM website. The required inputs for the program are upper air data and hourly surface air data in either the SAMSON or HUSWO format. To be consistent with using the upper air data from the San Juan International Airport, the surface air data from this airport was also used for this program. For use with the Mixing Heights Program, the hourly surface data converted from ISH to the SAMSON format described above was used. The processed mixing height data and surface air data were input into CALMET to create the gridded meteorological data for use in CALPUFF. Per the BART modeling guidance (BART, 2006), Lambert Conformal Coordinates (LCC) were used in CALMET and CALPUFF. 2.3 CALPUFF Input File The current “EPA Approved” version of CALPUFF is version 5.8, which was used for all of the CALPUFF modeling. The model includes a post processor called CALPOS T. The model was downloaded from the SRC (ww.src.org) website. CALPUFF used the gridded meteorological data generated by CALMET, as described above. For the input parameters to CALPUFF and the postprocessor CALPOST, the Federal Land Managers' Air Quality Related Values Workgroup (FLAG) Phase I Report - Revised (FLAG 2010) was used as a reference. This document was finalized on October 28, 2010. The regulatory default options for CALPUFF were followed, but the regulatory default check must be switched off because it erroneously expects all minimum turbulence velocities (SVMIN) to be 0.5 m/s, whereas it should also allow the default value of 0.37 m/s over water to be used. The determination of stack parameters and modeled emissions rates is discussed below. The background ammonia conditions used are found in the FLAG Phase I Report - Revised (FLAG 2010). As the document suggests, we useda background ammonia concentration of 0.5 ppb for forests. The background ozone conditions were calculated from the EPA’s Clean Air Status and Trends Network (CASTNET, http://www.epa.gov/castnet/data.html). The data provided by CASTNET is the hourly ozone concentrations at Lind Point in the Virgin Islands National Park. Since recent ozone dataMr. Robert Kelley March 31, 2011

EPA Contract No. EP-D-05-096, WA No. 5-16 Page 5 of 13


### corresponding to modeled years was not available from CASTNET, hourly values were averaged over each month of 2001 to produce a monthly value for use in each modeled year. Table 2 provides the background ozone concentrations used in the evaluation.
As indicated in Figure 3, the Federal Land Manager (FLM) has developed a receptor set that outlines the Virgin Island Class I area. Since this receptor grid does not allow for examination of single source contributions, MACTEC instead post-processed an additional receptor located at the IMPROVE monitor site. This allowed MACTEC to calculate source contributions, as well as create data which is directly comparable to the IMPROVE monitor. The FLM grid was also run through CALPUFF in case the data were needed, however the receptors were not post-processed with CALPOST. The FLMreceptor set was downloaded from the National Park Services (NPS) website (http://www.nature.nps.gov/air/maps/receptors/index.cfm) and converted to the Lambert Conformal Conic (NAD83, km) for the modeling. Figure 3 shows the FLM receptors.

### 2.4 CALPOST Input File The CALPOST post-processor is used to perform visibility calculations based on the concentration and visibility files created by the CALPUFF run. The input requires a selection of the type of visibility calculations to be used by the processor. The FLAG Phase I Report (2010) was used to determine the method of calculating visibility effects of the modeled pollutants. Method 6 in the model was selected in the model as the appropriate way to calculate visibility impacts. Method 6 uses monthly relative humidity (RH) adjustment factors applied to observed and modeled large and small particle to calculate the visibility effects of the speciated emissions. The algorithm used to calculate the changes in visibility changed between the 2000 and 2010 editions of the FLAG Phase I Report. Now, the total sulfate, nitrate and organic carbon compound concentrations are each split into two fractions, representing small and large size distributions of those components. The organic mass concentration used in this new algorithm has increased, sea salt (important for coastal locations) was added into the calculation, and site-specific Rayleigh scattering is used. The small and large particles, along with the sea salt concentration, were given relative humidity (RH) adjustment factors which are site-specific. The equation below shows the new equation for calculating beta extinction.

The current EPA-approved versions of CALPUFF and CALPOST are unable to properly calculate beta extinction. Therefore a spreadsheet that uses the output from the CALPOST model was developed to extract the necessary model results and apply the correct beta extinction calculation.

2.5 Modeled Sources MACTEC developed a list of thirty two sources for use in the model. Individual sources were selected to include the sources specified in the Work Plan. Table 5 provides a summary of the grouping of sources used in the model, and modeled emission rates for each source. The sources in each group are explained in more detail in the discussion below. The spreadsheets of calculate emission rate calculations are provided in Appendix A. Group 1 - St. Croix

–

Hovensa Point Sources: Sources in this category were selected from Table 6-4 of the AEG Anguilla Power Renewable Energy Power Generation Project. This group contains seven sources (6 of the largest sources and 1 aggregate of the remaining sources), representing a total of approximately 75% of St. Croix’s total emissions. Since there were over 170 sources on St. Croix, the model was limited to major emission points which were the electric utilities and the top 3 emitters of PM, SO2, or NOx. St. Croix sources were split between Groups 1 and 6, with Group 1 representing only the Hovensa refinery, and Group 6 representing all other St. Croix sources. Group 2

– Actual St. John Point Sources: Sources in this category represent the actual point sources provided to MACTEC by Bob Kelly of EPA Region 2 in the spreadsheet St. John

– Emissions Calculations.xls

. The spreadsheet has been incorporated into the emissions calculations presented in Appendix A. Stack parameters for these sources have been estimated by MACTEC using parameters for generic generators, since no such information was presented with the emissions calculations. This category contains five (5)

sources. Group 3

– Aggregate St. John Marine Sources: Marine sources at St. John include all Ferry, Cruise Ship, and Cargo Ship emissions specified in St. John

–

Emissions Calculations.xls. As a conservative assumption, all three types of marine sources were modeled as point sources located at the Cruz Bay docks, rather than spreading theMr. Robert Kelley March 31, 2011

### emissions over a greater area. The three different types of ships are represented with different stack parameters obtained from typical cruise ship data specifications. This group is not modeled simultaneously with Group 3a. Group 3a

– Aggregate St. John Marine Sources with Emission Reductions:

This is an alternative set of emission rates for the marine sources at St. John. The source parameters are identical to Group 3, but emission rates have been reduced by 85% for PM and SO2, and 80% for NOx. This is not modeled simultaneously with Group 3, and is used to examine the benefits of emissions reductions to the marine sources. Group 4

– Sample Puerto Rico Sources: Emissions and stack location are based on the AES Puerto Rico, L.P. 454 MW coal fired power plant in Guayama, Puerto Rico. The stack parameters are based on a similarly sized coal-fired boiler. Group 5 - Actual St. Thomas Sources: Emissions are based on the Virgin Islands Water and Power Authority (VIWAPA)

– Unit 23, at Krum Bay. It is a 39 MW turbine that burns no. 2 distillate fuel oil. The stack parameters are based on an engineering estimate for a similarly sized turbine. Group 6

– Other St. Croix Sources: Sources in this category are from Table 6-4 of the AEG Anguilla Power Renewable Energy Power Generation Project. This consists of eight total sources (seven actual and one aggregated source), representing all St. Croix emissions except for those included in Group 1 (from Hovensa). The project details over 170 separate point sources. To reduce model run times due to the extremely high number of small point sources on St. Croix, emissions from the remaining sources were modeled here as a single point source. The location and stack parameters were conservatively represented by placing the source in the same location as the largest emitter of PM10 on St. Croix, the Hovensa wet scrubber, which was modeled in Group 1. The stack parameters from the wet scrubber were also used so an identical plume would result, yielding an even more conservative modeled impact. The total emissions from the non-Hovensa sources represented in this group comprise approximately 25% of the total emissions from St. Croix.Mr. Robert Kelley March 31, 2011

EPA Contract No. EP-D-05-096, WA No. 5-16 Page 9 of 13


### Group 7

– Aggregate British Virgin Islands (BVI) Sources: This category represents emissions from total oil usage on the BVI. The oil usage data was selected from the Central Intelligence Agency (CIA) World Factbook (1000 bbl/day). The Department of Energy (DOE) website indicates that residual oil is not consumed in significant quantity in the BVIs, so only a distillate emission factor was estimated. The distillate oil emission rates were calculated from AP-42, Chapter 1.3 (Fuel Oil Combustion), conservatively assuming a sulfur content of 0.5% (Source: Latin America and the Caribbean Sulphur Levels in Diesel Fuel, UNEP). MACTEC created an area source representative of the island of Tortola. Tortola is the closest of the BVIs to St. John. The area source represents the largest city on Tortola, Road Town. It is represented as a 2.5 km2 

### square area source, covering the majority of the land area of Road Town. Group 8

– Simulated BVI Sources: The modeled area source represents general land clearing via open burning. The emission factors used were taken from AP-42 Chapter 11.9, Table 11.9- 1 for overburden. Section 13.2.3, “Heavy Construction,” advises using this factor for general land clearing. The area modeled is 100m x 100m and the location is based on sensible and possible locations of future land clearing. Group 9

–

St. John Paved and Unpaved Road Fugitive Sources: The modeled area source represents fugitive dust emissions from roadways on St. John. The emission rates were from the spreadsheet St. John

– Emissions Calculations.xls . Paved roads are responsible for 32.7 Tons per Year of particulate matter emissions on St. Johns, while unpaved roads produce 99.4 Tons per Year. The area modeled is a 5km x 10.4km rectangular region, representing an area equal to the 52 km2 

### land area of St. John. Group 10

–

Aggregate St. John Burning: The modeled area source represents all sources of fires on St. John, including open burning, forest fires, and structure fires. The emission rates were from the spreadsheet St. John

– Emissions Calculations.xls . The area is conservatively modeled as 3km by 3km square region, located at Cruz Bay, St. John.Mr. Robert Kelley March 31, 2011

St. John Residential Boilers: The modeled area source represents emissions from residential boiler usage on St. John. The emission rates were from the spreadsheet St. John

– Emissions Calculations.xls . The area is conservatively modeled as 3km by 3km square region, located at Cruz Bay, St. John. Group 12

–

St. John Miscellaneous Industrial Processes: The modeled area source represents emissions from other industrial sources on St. John. There are two sources represented by Group 12. The Majestic Concrete facility emits 0.32 Tons per Year of particulate matter, and residential construction emits 10.7 Tons per Year. The emission rates were from the spreadsheet St. John

– Emissions Calculations.xls . The area is conservatively modeled as 3km by 3km square region, located at Cruz Bay, St. John. Group 13

–

St. John Motor Vehicle Emission Sources: The modeled area source represents motor vehicle emissions on St. John. The emission rates were provided by an e-mail from Bob Kelly at EPA Region 2. The area modeled is a 5km x 10.4km rectangular region, representing an area equal to the 52 km2

Volume of Landfill Gas Flared on St. John (dry standard cubic feet/yr)

Note: According to VIWMA website: The Susannaberg Landfill on St. John was closed in the early 1990’s when an underground fire was discovered and extinguished. This facility now operates as a transfer station, as the solid waste on St. John is collected from the many disposal sites (bin sites) located strategically around the island fur use by the residents to dispose of their household waste. The waste is then taken to the Susannaberg Transfer Station, compacted and then barged to St. Thomas where it is transported to the Bovoni Landfill on the southeastern end of the island and disposed of there.
