Subject:	Draft Modeling Comparison of BLP and AERMOD for Primary
Aluminum

Introduction

	This memo describes an air dispersion modeling comparison conducted
between The Bouyant Line and Point (BLP) model and the American
Meteorological Society (AMS) and EPA Regulatory Model (AERMOD) contained
within the Human Exposure Model version 3 (HEM3). BLP was developed for
the Aluminum Association approximately 30 years ago to account for the
unique release characteristics of the long and hot potrooms
characteristic of primary aluminum smelters.   The result of the
modeling comparison was that the output of both the BLP model and HEM3
resulted in nearly the same risks for the pollutants modeled.  The
cancer risk estimates for the maximum individual risk to the person most
exposed (MIR) and the noncancer hazard quotient (HQ) were of the same
order of magnitude and within fifty percent of each other.

	Section 2 of this memorandum presents the facility source
characteristics provided by EPA.  Section 3 presents the emissions
estimates and toxicity inputs used in the analysis and Section 4
discusses the air dispersion modeling.  Results of the comparison are
presented in Section 5.

Source Characterization

	EPA provided the source locations and release characteristics for a
primary aluminum facility located in Montana that was used in this
comparison.  An aerial photograph and sketch of the details of each
potroom are presented in Figures 1 and 2.  As seen in the figure there
are 10 potrooms.  The potrooms were modeled in BLP as line sources and
in HEM3 as narrow area sources.  EPA’s release characteristics of the
10 potrooms (line/area sources) are a vent height of 60 feet, vent
length of 1,014 feet, vent width of 9 feet, with a median temperature of
76 degrees Fahrenheit.  There are also 11 point sources.  Ten of the
eleven point sources are alumina scrubber stacks and had stack heights
of 111 feet, stack diameters of 3.2 feet, exit temperatures of 232
degrees Fahrenheit, and exit velocities of 61 feet per second.   The
remaining stack, for the paste plant scrubber, was modeled as 71 feet
tall with a diameter of 2.75 feet, with the same exit temperature and
flow rate as the other stacks.  Table 1 presents the source identifiers
and their locations.

Emissions Estimates and Toxicity Inputs

	EPA provided emissions estimates of 20 polycyclic aromatic hydrocarbons
(PAH) emitted from the facility.  Nineteen of the compounds were
assigned to various polycyclic organic matter (POM) groups for modeling
within HEM3 based on the approach used in the National-Scale Air Toxics
Assessment (NATA).  These groups each have their own carcinogenic unit
risk estimate (URE) based on their relative potency to benzo(a)pyrene. 
Naphthalene, which does not have a URE, was not assigned to a group and
was the only compound to have a reference compound (RfC) for estimating
noncancer adverse health impacts.  Once the individual POMs are assigned
to groups, all HAP emissions in the group are summed to have one
emissions estimate per group.  Its chronic RfC is 0.003 milligrams per
cubic meter (mg/m3).  Table 2 identifies the POM group, the compounds
modeled assigned to the groups, and the group URE.  Emissions were
provided by EPA in units of tons per year (TPY) and modeled as such in
HEM3.  For BLP, the emissions were converted to grams per second (g/s)
based on the assumption of continuous operation throughout the year
(8,760 hours per year).  Table 3 identifies the source specific
emissions as modeled, while Attachment 1 contains the detailed emissions
data received from EPA.

Air Dispersion Modeling

	BLP is a Gaussian plume dispersion model designed to handle unique
modeling problems associated with aluminum reduction plants, and other
industrial sources where plume rise and downwash effects from stationary
line sources are important.  Since the time BLP was developed, EPA has
developed more advanced models than the preferred model of the day.  BLP
uses a single value, F prime (F’), to account for the buoyancy of a
building’s release and the building’s parameters (BLP User’s Guide
Equation 2-47).  For this application we calculated an F’ value of 45
m4/s3.  BLP is cumbersome to use and must be run separately for each
pollutant.  HEM3 contains as its dispersion model the EPA’s regulatory
model AERMOD2. AERMOD incorporates air dispersion based on planetary
boundary layer turbulence structure and scaling concepts, including
treatment of both surface and elevated sources, and both simple and
complex terrain.  AERMOD contains algorithms to calculate plume rise. 
BPIPPRIME, calculates the impacts of buildings on the dispersion of
releases.  

	HEM3 contains not only the AERMOD dispersion model, but also datasets
of toxicity information, terrain, meteorological files, census data at
the block level, and algorithms for combining the model results and data
to estimate risk.  When possible we used HEM3 as a consistent data
source for both model inputs and to calculate risks.   However, BLP does
not calculate risks thus the BLP risk estimates were prepared using a
spreadsheet and only the MIR was calculated and will be compared to the
HEM3 run.  HEM3 is being run to estimate residual risk for the other
source categories and so many of the processing steps have been
automated.  Automation not only results in a much lower level of effort,
it also eliminates opportunities for potential human error.

	We used the Universal Transform Mercator (UTM) coordinate system rather
than latitude and longitude for both the BLP and the HEM3 models so the
coordinates provided by EPA were converted from decimal degrees of
latitude and longitude to UTM coordinates using one of many converters
available on the web.   Tables 4 through 6 presents the locations of the
emissions sources as modeled together with the base elevations for the
sources and receptors, and the hill height scale for the receptors,
obtained from HEM3.  HEM3 was used to identify the 30 receptors, the
census block centroids within 3,000 meters of the facility center (see
Table 7).   Other options selected for the modeling in both BLP and HEM3
are presented in Table 8.

Table 8.  Modeling Options for the Model Comparison of BLP and AERMOD

AERMOD Options	Value

Rural land use, no deposition or depletion, terrain option	Site specific
terrain values from HEM3. 

Receptors	Census blocks within 3,000 m of facility center. 

Meteorological Data	Great Falls, MT 1991 AERMET file from within HEM3.

Results

	When modeled using terrain, the standard method used in residual risk
assessments, the HEM3 MIR was estimated to be 1.28 x 10-4 excess cancer
cases per million of people exposed (see Table 9).  The HQ for
naphthalene, the only compound with an RfC, was 0.00035.  Figure 3 shows
the location of the MIR as well as uses color coding to identify the
approximate risk estimate for each census block.  

	For the BLP modeling with terrain, the MIR was estimated to be 1.59
x10-4 excess cancer cases per million of people exposed and the HQ for
naphthalene was 0.00020.  Appendix W, The Guideline on Air Quality
Models, recommends the BLP not be run using the terrain option.  In a
BLP run without terrain the same maximum risks were estimated as when
terrain was used and they occurred at the same receptor.   A comparison
of the air concentration results from BLP with and without terrain is
presented in Attachment 2.  The maximum values with and without terrain
occur at a receptor close to the facility where terrain does not have a
large impact on the results.   However, the attachment shows that at
other receptors there is a difference in the modeling results when
terrain is used.

Note:  Census blocks depicted in green are estimated to have an MIR less
than 1 in one million, blocks in yellow are estimated to have an MIR
between 1 and 10 in one million, and blocks in red are estimated to have
an MIR greater than 100 in one million.

 However, in order to model with HEM3 for this source category as EPA is
modeling others for which building characteristics are not known, for
this application we did not include the use of BPIPPRIME.   The result
is a comparison of BLP and HEM3 as it is being run for estimating
residual risk, not a comparison of the most precise way to model the
facility using each of the models.
