1.0    Introduction and Summary  TC “1.0    Introduction and
Summary” \f C \l “1”  

This document presents the 2002 base year emission inventory for Rhode
Island.  The United States Environmental Protection Agency (EPA) has
designated 2002 as the base year for State Implementation Plan (SIP)
revisions developed to show attainment of the 8-hour ozone and
particulate matter smaller than 2.5 microns (PM2.5) National Ambient Air
Quality Standards (NAAQS).   The EPA has classified Rhode Island as a
moderate nonattainment area for the 8-hour ozone standard.    Rhode
Island is in attainment of the PM2.5 standard at this time but this
document includes a PM2.5 inventory that has been developed for regional
modeling purposes.  Additionally, the Consolidated Emissions Reporting
Rule (CERR) requires states to prepare an inventory every three years
for criteria pollutants.  This document, along with electronic data
submitted in June 2004, meet the criteria specified in the CERR. 

 Scope  TC “1.1  Scope” \f C \l “2”  

This inventory addresses emissions of volatile organic compounds (VOC)
and oxides of nitrogen (NOx), which are ozone precursors, as well as
sulfur dioxide (SO2), carbon monoxide (CO), ammonia (NH3), PM2.5
(filterable and condensable fractions) and particulate matter less than
10 microns (PM10) (filterable and condensable fractions).  The inventory
includes emissions from stationary point, stationary nonpoint, on-road
mobile and non-road mobile sources and covers all areas of the State,
since the entire State is considered a nonattainment area for ozone.

1.2   Purpose  TC "1.2   Purpose" \f C \l "2"  

The 2002 base year inventory will be used for the following purposes:

Rhode Island, a moderate nonattainment area for the 8-hour ozone
standard, must submit a SIP revision to the EPA in 2007 demonstrating
that the State will be in attainment of the 8-hour ozone standard by
2010.  The attainment SIP must include a reasonable further progress
analysis (RFP) that shows that ozone precursor emissions in the State
will be reduced by 15% between 2002 and 2008.  The inventory in this
document will be the 2002 RFP inventory and will be the basis for
projecting future year inventories for use in the RFP and in other parts
of the attainment demonstration.  

Although Rhode Island is in attainment of the PM2.5 standard, this
inventory, along with inventories from neighboring states, will be used
for regional modeling to evaluate the effectiveness of control
strategies to address regional attainment of the PM2.5 standard as well
as visibility degradation in Class 1 areas in the region.

1.3 Responsible Agency  TC "1.3  Responsible Agency" \f C \l "2"  

The Office of Air Resources of the Rhode Island Department of
Environmental Management (RI DEM) prepared the inventory.   Other Rhode
Island agencies that contributed information necessary for calculating
emissions include the Division of Motor Vehicles of the Department of
Administration and the Department of Transportation.   EPA and the Mid
Atlantic Regional Air Management Association, Mid-Atlantic/Northeast
Visibility Union (MARAMA/MANE-VU) have developed emission inventories
for several nonpoint source categories which were used in this inventory
as noted in the report.

1.4   Data Format  TC "1.4   Data Format" \f C \l "2"  

Both annual and typical summer weekday emissions for the 2002 base year
are provided in this document.  In addition, all base year emissions
have been entered in the EPA’s National Emissions Inventory (NEI)
database.

1.5 Stationary Point Source Inventory  TC "1.5  Stationary Point Source
Inventory" \f C \l "2"  

Chapter 2 of this document presents the results of the stationary point
source inventory.  The point source inventory was prepared from the
results of a mail survey of facilities in the State.  The names and
calculated emissions of all stationary commercial and industrial sources
which emitted at least 10 tons of VOC, 25 tons of NOx, or 100 tons of CO
in 2002 are listed in Chapter 2.    In all, 66 point sources were
identified.

Chapter 2 includes sample calculations documenting the methodologies
followed for the following types of sources:

	

Surface Coating Operations for sources with and without control
equipment

Degreasing Operations

Fuel Combustion in boilers

Boat Building

1.6   Stationary Nonpoint Source Inventory  TC "1.6   Stationary
Nonpoint Source Inventory" \f C \l "2"  

Chapter 3 of this document presents stationary nonpoint source emissions
estimates for several source categories.   The emissions estimates for
some of these source categories are taken from the EPA National
Emissions Inventory (NEI) of nonpoint sources.    For some source
categories, Rhode Island used emission inventory estimates developed by
MARAMA/ MANE-VU Chapter 3 outlines the methodologies and the sources
used to calculate emissions from nonpoint sources. The following
nonpoint source categories are included in this report:

Gasoline Distribution

Portable Fuel Containers

Architectural Coating

Automobile Refinishing

Industrial Adhesives

Commercial/Consumer Solvent Use

Surface Cleaning

Surface Coating

Graphic Arts

Process Solvents

Traffic Paint

Publicly Owned Treatment Works(POTWS)/Composting

Paved and Unpaved Roads

Residential/Nonresidential Construction

Fires

Residential Wood burning

Commercial Cooking

Cutback and Emulsified Asphalt

Small stationary source fossil fuel use

Agricultural production

Agricultural Tilling

Agricultural Fertilizer

Industrial Refrigeration

1.7   Mobile Source Inventory  TC "1.7   Mobile Source Inventory" \f C
\l "2"  

Non-road mobile source emissions are presented in Chapter 4 of this
document. Emissions from non-road engines were calculated using the EPA
Nonroad Emission model, core model version 2005a, February 2006 The
recently revised non-road model predicts emissions generated from more
than 80 basic and 260 specific types of equipment. Typically, equipment
in this category includes recreational vehicles, logging equipment,
tractors, construction equipment, residential/commercial lawn garden and
water pleasure craft. The model does not predict emissions from
commercial marine vessels, locomotives or aircraft.    

On-road mobile source emissions were calculated using EPA’s Mobile 6
model.  Input data necessary to run the model were obtained from the
Department of Transportation and the Division of Motor Vehicles of the
Department of Administration.

1.8 Summary of Emissions Data  TC "1.8 Summary of Emissions Data" \f C
\l "2"  

Annual emissions and emissions during a typical summer weekday were
calculated for the ozone precursors, VOC and NOx. Annual emissions were
calculated for CO, PM2.5, PM10 and NH3 as well as for the ozone
precursors.  Total 2002 emissions annual and typical summer weekday
emissions for Rhode Island are as follows:

Pollutant	Total Emissions (tons)

	Annual	Summer Weekday

VOC	41,494	117

NOx	27,924	73

CO	269,981	N/a

PM2.5	3,863	N/a

PM10	8,480	N/a

NH3	1,698	N/a

The distribution of typical 2002 summer weekday emissions of VOC and
NOx by source type is as follows:

Source Type	Summer Weekday Emissions (tons/day)

	VOC	NOx

Stationary point sources	10.3	 7.0

Stationary nonpoint sources	47.9	3.4

Non-road  mobile sources	26.8	19.7

 2.0 Stationary Point Sources  TC "2.0 Stationary Point Sources" \f C
\l "1"  

2.1 Introduction  TC "2.1 Introduction" \f C \l "2"  

This section documents the development of the Rhode Island Nonattainment
Area stationary point source list and characterizes the overall process
used to obtain point source emission estimates by describing the data
collection, verification and emission estimation techniques used.  For
the purposes of this emission inventory, point sources are defined as
stationary commercial or industrial operations that emit 10 or more tons
per year (tpy) of VOC, 25 or more tpy of NOx, 100 or more tpy of CO
and/or 100 or more tpy of PM. The point source inventory consists of
actual emissions for the base year 2002 for point sources in the five
Rhode Island nonattainment counties.

RI DEM’s Office of Air Resources was the sole agency responsible for
compiling the point source inventory.  RI DEM was responsible for
identifying point sources meeting the cutoff criteria, verifying and
documenting the method used to calculate emissions from each source and
summarizing and presenting its findings.

The remainder of this section details the point source data collection
techniques, explains emission estimation procedures and provides
detailed tables of point source emissions estimates.

2.2 Compiling the point source list  TC "2.2 Compiling the point source
list" \f C \l "2"  

This section describes methods used to develop the initial point source
list from which point source emissions for the 2002 Rhode Island base
year inventory were estimated.  This section is included in order to
demonstrate that the point source list is as complete as possible.

Point source data collection activities for the 2002 base year inventory
began in January 2003.  An existing point source emission inventory,
compiled for the 1990 base year and subsequently used to develop 1996
and 1999 projection inventories, formed the starting point for the point
source list. The inventory list had been updated annually since its
initial development.  Manufacturing sources that emit criteria or
hazardous air pollutants and sources known to be major fuel users are
included in the inventory.  

The Rhode Island Directory of Manufacturers was used to search for any
new or previously unidentified manufacturing sources in the State. 
Sources in manufacturing SIC codes that have more than 10 employees were
added to the inventory form distribution list.  Internet searches were
used to obtain lists of boat builders in Rhode Island and all boat
builders identified were added to the list.  In addition, the Office of
Air Resources’ list of permitted air pollution sources was reviewed
and all new sources from that list were added.  Potential point sources
identified by staff engineers were also added.  In total 600 sources
were inventoried for the 2002 base year inventory.

Rhode Island’s 2002 Point Source Inventory mailing was first sent out
in February 2003.  Forms were due April 15, 2003, and those sources that
had not returned their forms by that date were sent a second set of
forms with a Letter of Noncompliance.  Approximately 85 forms were not
returned.  Based on the type of industry and the number of employees at
these sources, it was determined that the sources that did not return
the forms would not have met the thresholds to be considered point
sources.  Emissions from these sources are accounted for in the nonpoint
source portion of the inventory.

Emissions were calculated as described in section 2.3 below. Sources
with emissions at or above the thresholds in section 2.1 were included
in the final comprehensive point source list. The following table shows
that list, including includes the name, location and annual emissions in
tpy by pollutant for each identified point source.

*VOC EMISSIONS WITH RULE EFFECTIVENESS

 2.3 Emissions Estimation Procedures  TC "2.3 Emissions Estimation
Procedures" \f C \l "2"  

2.3.1 Exclusion of nonreactive VOC from Emissions Totals  TC "2.3.1
Exclusion of nonreactive VOC from Emissions Totals" \f C \l "3"  .

Only reactive VOCs, as defined by the EPA, are reported in this
inventory.  Both reactive and nonreactive VOCs were reported to RI DEM
on the emissions inventory forms.  All emissions were speciated and
entered into the RI DEM database by CAS number.  To determine which
facilities should be considered point sources for the base year
inventory, VOC emissions were summed, excluding those compounds which
are designated by EPA as nonreactive.

For some source categories, emission factors for total VOC from the EPA
AP-42 document were used when speciated emissions factors were not
available.  Many of the sources in those categories do not emit
nonreactive VOC.  When emission factors for methane and non-methane VOC
were both given in AP-42, the emission factor for non-methane VOC was
used in calculations.

2.3.2 General Procedures  TC "2.3.2 General Procedures" \f C \l "3"  

In the majority of cases, emission estimates for point sources were
calculated using material balance methods.  For other sources, emission
factors from AP-42 and source test data were used.  Emissions estimates
were adjusted to reflect rule effectiveness considerations and
seasonality where applicable.  The following equation was used to
account for rule effectiveness and seasonal adjustments:

	Es =    EA*Ts   [1- Ce (RE)]

           	D*Ws

Es = Seasonally adjusted (summer weekday) emissions (lb/day)

Ea = Annual emissions of VOC, NOx, CO or PM (lb/year)

Ts = Throughput during the ozone season, as a fraction of annual
throughput

D = Days in operation per week (days/week)

Ws = Weeks of ozone season (weeks/year)

Ce = Control efficiency

RE = Rule effectiveness

In the following sections, examples are provided to show how emissions
estimates were calculated for the point sources.

  

2.3.3   Emissions Calculations for Sources using Volatile Organic
Liquids for Degreasing, Cold Cleaning, Miscellaneous Industrial Solvent
Use and Surface Coating without Control Equipment  TC "2.3.3  
Documentation for Sources using Volatile Organic Liquids for Degreasing,
Cold Cleaning, Miscellaneous Industrial Solvent Use and Surface Coating
without Control Equipment" \f C \l "3"  

For point source degreasing, cold cleaning, surface coating and/or other
miscellaneous operations without control equipment, VOC emissions were
calculated by material balance.  Credit was given for solvent which was
manifested off-site.  In cases in which the percentage of a chemical in
hazardous waste was unknown, a default value of 80% was used.  This
figure was based on information from the State’s main recycler of
solvents.

Ozone season activity levels were based on summer production levels
reported by each company.  Typical summer day emissions were calculated
with the formula in section 2.3.2 using the seasonal activity and
operating schedule information reported by the company.  Emissions were
speciated and non-reactive solvents were not included when determining
whether a source met the 10 tpy threshold.  Example summary information
and calculations for a degreaser follow.

Sample Mass Balance Calculation

Degreaser 

 	 

Year beginning inventory	700 pounds trichloroethylene

Trichloroethylene purchased 2002	10,000 pounds

Year ending inventory	200 pounds

Amount waste solvent reported manifested as hazardous waste	3,000 pounds

Percent of manifested waste that is this chemical	Unknown - 80% default
assumed

Production and operating information	24% of annual production in
June-August

 	Operating hours: 8hrs/day, 5 days/wk

 	50-wks/yr (2 wk shutdown July)

Emission Type	Calculation

Annual Emissions	(700+10,000) - (200 + (3,000*.80)) 

= 8,100 pounds per year

Typical Ozone day	(8,100 lbs * 0.24) / (5days/wk *10 wks/ozone season) 

= 39 lbs/day

2.3.4   Miscellaneous Surface Coating and Printing Sources with Control
Equipment  TC "2.3.4   Miscellaneous Surface Coating and Printing
Sources with Control Equipment" \f C \l "3"  

For surface coating or printing operations, the surveys asked for
information about the coating and ink formulations used at the facility,
including the gallons of coating used, the density of the coating, the
percent total VOC in the coating and the percent of listed chemicals in
the coating.  Spreadsheets were developed for each of the companies.  In
most cases, shipments of waste coating sent off- site as manifested
wastes were assumed to have the same solvent profile as the coating used
at the facility.  If the company provided results of testing of waste
for components, those data were used.  If the company had control
equipment, the capture and destruction efficiency of the control
equipment was obtained from either stack test data or permit conditions.
 Seasonal production and operation data provided on inventory forms were
used to determine daily emissions.  

Rule effectiveness adjustments were applied to VOC emissions directed to
air pollution control equipment as required by EPA.  In most cases, RI
DEM used the EPA default adjustment of 80%, which was multiplied by the
efficiency of the control equipment and increased the estimated amount
of VOC released from the facility.  The rule effectiveness adjustment is
intended to account for the control equipment not having been operated
at all times that it was supposed to have operated and for its
efficiency not being optimal at all times.  For five facilities with
control equipment, the Office calculated facility-specific rule
effectiveness adjustment factors using the questionnaire in the November
1992 EPA document entitled Guidelines for Estimation and Applying Rule
Effectiveness for Ozone/CO State Implementation Plan Base Year
Inventories.  Rule effectiveness adjustment factors calculated for those
facilities are as follows:

Company			Adjustment Factor

Arkwright				90

NEPTCO				89	

Providence Metallizing		86

Stanley Bostitch			89

Union Industries			91

		



Sample of Surface Coating Calculation

Gallons of Coating used in 2002	2,000 gal

Percent VOC in coating by weight	80%

Density of the coating	7.36 lbs/gal

Amount manifested	55 gallons

Percent of manifested waste that contains VOC (default is 80%)	80%

Calculation of amount of waste that is VOC.	Gallons of waste * average
density * percent waste that is VOC = pounds of VOC manifested

55 gal * 7.36 lb/gal * 80% = 324 lb

Calculation of uncontrolled pounds of solvent emitted.	Gallons of
coating used  * % VOC in coating * density of coating – pounds VOC
manifested = pounds emitted uncontrolled

2,000 gal * 66% VOC * 7.36 lbs/gal  – 324 lbs = 9,391 lb VOC 

Calculation of controlled emissions assuming an overall control
efficiency of 97%.  	Uncontrolled emissions * ( 1- overall efficiency)=
emissions without rule effectiveness

9,391 lbs * (1 - 0.97)  = 282 lbs of VOC without  RE

Calculation of VOC emissions with rule effectiveness (RE) using a
default RE factor of 80% and assuming overall control efficiency is 97%.
Uncontrolled emissions (1 - overall efficiency * RE factor)= emissions
with rule effectiveness

9,391 lbs * (1- 0.97 * 0.8)  = 2,104 lbs of VOC with RE 

Calculation of typical summer weekday emissions assuming 25% of the
surface coating took place in June - August and the facility operated 65
days.	Annual emissions * seasonal percentage / # of days operated
June-August

(With RE)

2,104 lbs * 0.25 / 65 days = 8.09 lb/day

2.3.5 Stationary Source Fuel Combustion  TC "2.3.5 Stationary Source
Fuel Combustion" \f C \l "3"  

All sources which burn fuel for electric generation, building heat or
for processes were required to submit data on the amount and type of
fuel burned by each type of equipment.  AP-42 contains emission factors
based on the type of source - utility, industrial or
commercial/institutional, the fuel type, and the size of the fuel
burning equipment.  AP-42 also contains emission factors for emergency
generators, engines and turbines.  Appropriate AP-42 emissions factors
were used to calculate emissions for all listed point sources except for
sources that provided data from continuous emission monitors or results
from stack testing.

  

Sample Boiler Calculation

Boiler size	75 mmbtu/hr industrial boiler

Type of fuel burned	No. 6 fuel oil

Amount of fuel burned 2002	50,000 gallons

Percent Sulfur in fuel	1%

Percent of fuel burned June-August	10%

Number of days operated June-August	30

Emission factors from AP-42

NOx  = 75 lbs/103 gal

SO2 = 159 * (% Sulfur) lbs/103 gal

CO =  5 lbs/103 gal

PM10  =((7.17*(1.12* (% Sulfur) +.37)+1.5) lbs/103 gal

VOC =  0.28 lb/103 gal	Amount of fuel burned * emission factor = pounds
emitted

NOx

50x103 gallons * 75 lb/103 gal = 3,750 lbs emitted

SO2

50x103 gallons * 159(1) lb/103 gal = 7,950 lbs emitted

CO

50x103 gallons * 5 lb/103 gal = 250 lbs emitted

PM10

(50x103 gallons* ((7.17*(1.12(1)+.37))+1.5) lb /103 gal) = 609 lbs
emitted

VOC

50x103 gallons * 0.28 lb/103 gal = 14 lbs emitted

Typical summer weekday emissions (VOC and NOx only)	Annual emissions *
seasonal %  / number of days operated June-August

NOx

3,750 lb * 10% / 30 days = 12.5 lb/day

VOC

14 lb* 10% / 30 days = 0.05 lb/day

2.3.6 Gasoline Storage and Handling Facilities  TC "2.3.6 Gasoline
Storage and Handling Facilities" \f C \l "3"  

Point source emissions from stationary source gasoline distribution
operations include emissions from all activities attributable to bulk
gasoline terminals.  These include emissions from gasoline loading,
storage tanks, and leaks from valves, flanges and pumps  There are
currently two bulk gasoline terminals operating in Rhode Island, Mobil
and Motiva.  Both of these sources provided the Office with emission
statements that detailed all emission points at the facility.  The
emissions statements were reviewed and found to be accurate.  Both
terminals ran the TANKS 3 program to estimate their emissions from the
storage tanks.   The terminals also supplied data on the amount of fuel
throughput while the vapor recovery unit was both operating and not
operating.   Loading losses were estimated using an emissions rate
determined by stack testing done at the facilities.   Neither facility
reported loading fuel on to barges.  Ballasting of barges is not
typically done dockside so no barge ballasting emissions were assumed.

2.3.7 Boat Building  TC "2.3.7  Boat Building" \f C \l "3"  

Emissions from boat building operations were calculated using the EPA
recommended method.  Section 4.4 of AP-42, “Polyester Resin Plastics
Fabrication” has been removed and now references emission factors
developed by the American Composites Manufacturers Association (ACMA). 
Those emissions factors are based on type of application method used, -
hand lay up, spray lay up or gelcoat spraying- and the percent styrene
in the resin.  Boat manufacturers were required to submit data on the
amount of resin used, the percent styrene in the resin and the type of
application used to apply each resin.    A spreadsheet was developed for
each boat builder.   

The ACMA emissions factors were not used for TPI in Warren.  TPI uses a
specialized vacuum bagging system for resin application.  The company
has determined emissions factors for this process through emissions
testing.  These factors were used for TPI.

Sample Boat Builders Calculation

Amount of Resin A used	4,000 pounds

% styrene in resin	35%

Application Method used	Hand lay up

Emission factor from ACMA table	95 lbs styrene emitted/ton of resin
processed

Emissions from resin A	Tons resin used * emission factor = lbs styrene
emitted

(4,000 lb/2,000 lb/ton) * 95 lbs styrene / ton resin = 190 lbs styrene
emitted

3.0 NONPOINT SOURCES  TC “3.0  NONPOINT SOURCES” \f C \l “1”  

EPA has prepared a nonpoint inventory for several source categories. 
Emissions methodologies used in that inventory are outlined in a report
prepared for the EPA by EH Pechan and Associates entitled
“Documentation for the Draft 2002 Nonpoint Source National Emission
Inventory for Criteria and Hazardous Air Pollutants“ (March 2005
version) hereinafter referred to as the Documentation.  Emissions
estimates in the EPA inventory were accepted by Rhode Island and used
for this nonpoint source inventory for the following source categories: 
 

Aviation Gasoline Distribution

Commercial Cooking

Nonpoint Source Fuel Combustion     

Construction (residential, non-residential and road)

Gasoline Distribution

Open Burning – Structural Fires

Solvent Utilization

Publicly Owned Treatment Plants (POTWs) (VOC only)

Paved/Unpaved Roads

Pesticide Application

Portable Fuel Containers

Agricultural Production

EH Pechan and Associates, under contract with MARAMA/MANE-VU, developed
emissions inventory estimates for residential wood combustion, open
burning (residential waste), industrial refrigeration, POTWs (NH3 only)
and composting activities.  These reports can be found online at the
following web address:   HYPERLINK "http://www.marama.org/visibility/" 
http://www.marama.org/visibility/ .  The Pechan estimates for those
categories were used for the Rhode Island inventory.

EPA has also published a series of guidance documents as part of its
Emission Inventory Improvement Project (EIIP) which contain
methodologies for calculating emissions from several source categories. 
These methodologies were used to calculate emissions for cutback and
emulsified asphalt application operations and for determining seasonal
activity factors for nonpoint source categories.  

For source categories for which emissions were calculated on a per
capita basis, the following 2002 population data, from the US Bureau of
Census, were used:

County	Population

3.1 Emissions from Nonpoint Source Gasoline Distribution Losses  TC "3.1
 Emissions from Nonpoint Source Gasoline Distribution Losses" \f C \l
"2"  

Annual emissions estimates for nonpoint source gasoline distribution
were obtained from the EPA gasoline distribution inventory that was
developed for the final 2002 National Emissions Inventory.  EPA was
required to develop that national inventory to provide a consistent data
set for evaluating the impacts of potential regulatory alternatives to
support the Mobile Source Air Toxics Rule.  Since that inventory used
updated emission estimation methods, it was used in this inventory for
nonpoint sources.  The methodology is outlined in the Documentation.

Annual emissions were calculated for gasoline pipelines, bulk storage
terminals, gasoline tank trucks in transit, gasoline Stage I systems at
service stations, gasoline Stage II systems at service stations and
gasoline underground storage tank breathing and emptying losses. 
Emissions from bulk gasoline terminals and plants included in the EPA
report were not included in this section of the inventory since the
terminals in Rhode Island were included in the point source inventory.  
The data for gasoline pipelines was also excluded since no major
pipelines exist in Rhode Island.

To estimate pounds emitted per summer week day (ppsd), monthly data on
gasoline sales were obtained from the Division of Taxation.  From those
data it was determined that 27% of the gasoline was distributed during
the months of June, July and August.  

Gasoline distribution emissions by county for Rhode Island are as
follows:

3.2 Aviation Gasoline  TC "3.2 Aviation Gasoline" \f C \l "2"  

Rhode Island used the emissions estimates developed by the EPA for
emissions from aviation gasoline distribution for this emissions
inventory.  The methodologies used to calculate emissions for this
category are contained in the Documentation.  No emissions are listed
for Bristol County since there are no airports in that country.

The activity data used to calculate emissions for this category, the
amount of aviation gasoline distributed, was obtained by the EPA from
the “Petroleum Supply Annual for designated Petroleum Administration
Districts.”  This amount was then allocated to the counties based on
the landing and takeoff data for general aviation flights in each
county. 2002 emissions from aviation gasoline distribution operations
are as follows:

3.3 Portable Fuel Containers

Rhode Island accepted the emissions estimates for portable fuel
containers that were prepared by EPA and the MARAMA/MANE-VU contractor
MACTEC.  Emissions estimates were calculated by applying an emissions
factor to the number of residential housing units in each county.  An
assumption was made that 46% of the households had gas cans.  2002
emissions from portable fuel containers are as follows:

3.4 Solvent Utilization  TC "3.4 Solvent Utilization" \f C \l "2"  

EPA developed emission estimates for eleven nonpoint source categories:
architectural surface coating, automobile refinishing, commercial and
consumer products, dry cleaning, graphic arts, industrial adhesives and
sealants, industrial surface coating, pesticide application, process
solvents, solvent cleaning, and traffic paints. The methodology used to
estimate emissions for these categories is contained in the EPA report
entitled “Solvent Mass Balance Approach for Estimating VOC Emissions
from Eleven Point Source Categories,” which can be found online at  
HYPERLINK "http://www.epa.gov/ttn/chief/net/2002inventory.html" 
http://www.epa.gov/ttn/chief/net/2002inventory.html  . 

Rhode Island used the EPA emissions estimates for all of these sources
categories except commercial and consumer products and dry cleaning in
the 2002 inventory.  All drycleaners in the State were sent emission
inventory forms, which were returned to the Office with actual solvent
usage.  These data are more accurate than the data contained in the EPA
report and were therefore used for calculating emissions from
drycleaners.  Emission factors contained in the Documentation were used
to calculate emissions from commercial and consumer products, to be
consistent with other states in the region.

Pounds of emissions per summer weekday for nonpoint sources were
calculated using the default seasonal allocation contained in Volume 3,
Chapter 4 of the EIIP.  For all categories except for architectural
coating, the seasonal adjustment factor was assumed to be 0.25 and the
number of days of activity 5 days per week.  For architectural coating,
the seasonal activity factor is 0.33 and the number of activity days is
7.  

2002 VOC emissions from industrial process chemical manufacturing,
architectural coating, traffic marking, industrial adhesive and
non-point surface coating operations are summarized in the following
tables:

3.6 Cutback and Emulsified Asphalt  TC "3.6 Cutback and Emulsified
Asphalt" \f C \l "2"  

Emissions from cutback and emulsified asphalt were calculated following
the methodology outlined in Chapter 17 of the EIIP document. 
Information on the amount of cutback and emulsified asphalt applied in
the State was obtained from Hudson Asphalt.  Hudson is the only supplier
of these products in Rhode Island.  They supplied the following
information:

Cutback Asphalt

Total Gallons used 2002 			629,556

Gallons used for patch (June-Aug)	    6,060

Gallons MC3000 (June-Aug)		       706

Emulsified Asphalt

Total Gallons used 2002			194,712

Gallons June –August			  89,518

All cutback asphalt used is medium cure with a density of 7.82
lbs/gallon and a diluents concentration of 35%.  The density of
emulsified asphalt is 8.3 lbs/gallon. From EPA guidance documents it was
determined that 70% of the diluents would evaporate.  

Total emissions from cutback asphalt:

Gallons used * density * percent diluent * % evaporation

629,556 gallons *7.82 lb/gal * 35% diluent * 70% evaporation/ 2,000
lb/ton = 603 tons per year

For emulsified asphalt the emission factor is 9.2 lbs/barrel (weight per
barrel 350 lb).

Total emissions from emulsified asphalt

194,712 gallons*8.3 lb/gallon * 9.2lbVOC/350 lb asphalt/ 2000 lb/ton =
21.24 tons per year

Summer weekday emissions were determined by assuming that cutback and
emulsified are applied 5 days per week based on information obtained
from Hudson Asphalt.    Asphalt use was apportioned to the counties
according to population.  2002 VOC emissions for cutback and emulsified
asphalt are as follows:

3.7 Dry cleaning  TC "3.7 Dry cleaning" \f C \l "2"  

Dry cleaning sources in the State use either perchloroethylene or
Stoddard solvent as a cleaning solution.  Dry cleaning sources are
inventoried annually for solvent use.  The majority of the drycleaners
use perchloroethylene, which is a hazardous air pollutant but is not
considered a VOC because of its low photochemical reactivity. 
Therefore, only the emissions of Stoddard solvent are included in the
VOC calculation for this source category.  Only three facilities in the
State used Stoddard solvent in 2002.  It was assumed that all Stoddard
solvent purchased was emitted.  To derive typical summer weekday
emissions, data supplied by the facility on seasonal throughput and
number of days operated during June- August 2002 were used.  The annual
data were multiplied by the seasonal throughput and divided by the
number of days operated during the months of June through August to
calculate average pounds per summer weekday.  2002 VOC emissions from
dry cleaning operations are as follows:

3.8 Publicly Owned Treatment Works (POTWs) and Composting  TC "3.8 
Publicly Owned Treatment Works (POTWs) and Composting" \f C \l "2"  

The MARAMA/MANE-VU contractor EH Pechan developed an ammonia emissions
inventory for POTWs and an ammonia and VOC inventory for composting
operations. These emissions estimates were accepted by Rhode Island for
the 2002 inventory.  VOC emissions were calculated using an emission
factor contained in the Documentation.

Pechan obtained information on wastewater flow and biosolids generation
from EPA’s Office of Wastewater Management, Envirofacts, and the New
England Biosolids and Residuals Association.  The emissions were
allocated to the counties based on the location of the POTWs.  The
wastewater flow rates by county are:

County	Flow rate (106 gal)

Bristol	1,644.74

Kent	3,314.78

Newport	3,232.79

Providence	37,913.99

Washington	2,531.76

The ammonia emissions factor for POTWs was obtained from the EH Pechan
and Associates report entitled “Estimating Ammonia Emissions from
Anthropogenic Sources, Draft Final Report (April 2003).” The VOC
emission factor was obtained from the Documentation.

The following emission factors were used:

3.9 Small Stationary Source Combustion  TC "3.9 Small Stationary Source
Combustion" \f C \l "2"  

EPA has developed an emissions inventory for residential, commercial/
institutional, and industrial combustion.  To avoid double counting of
emissions from industrial and commercial/institutional sources, the
emissions from fuel combustion reported in the point source section were
subtracted from the EPA calculated emissions.

The methodology used to calculate emissions is contained in the
Documentation.  The activity data were obtained from the Department of
Energy, Energy Information Administration 2001 “State Energy Data
Report”.  For the nonresidential sector, fuel consumption was
allocated to the counties based on County Business Patterns employment
data in NAICS codes 31-33.  For residential consumption, fuel was
allocated to the counties based on population distribution.  Pounds per
summer day were determined using the seasonal activity factors in the
EIIP.  For residential combustion, the activity factor is 0.08 with
activity 7 days per week.  For commercial/institutional combustion the
factor is 0.15 with activity 6 days per week.

Calculated 2002 emissions from small stationary source combustion
sources, by fuel and source type, are displayed in the following tables:

3.11	Commercial Cooking  TC "3.11Commercial Cooking" \f C \l "2"   

Rhode Island accepted the emissions inventory EPA developed for
commercial cooking.  The methodology used is contained in the
Documentation. 

Commercial cooking emissions were estimated for five source categories;
chain driven char broilers, under- fired char broilers, flat griddles,
clamshell griddles and deep fat fryers.  Activity data used for all but
deep fat frying of French fries was obtained from survey data contained
in a Public Research Institute report on charbroil activity in the State
of California.  For deep fat frying of French fries the activity data,
mass of frozen potatoes sold, was obtained from the US Department of
Agriculture.  The emissions factors used were obtained from the EPA
report entitled “Methods for Developing a National Inventory for
Commercial Cooking Processes: Technical Memorandum.”  Emissions were
allocated to the counties using the number of restaurants in Dun and
Bradstreet industry classifications that use commercial cooking
equipment.  

Emissions estimates for criteria pollutants from commercial cooking
operations are summarized below.

2002 PM10 and PM2.5 emissions were grown from 1998 emissions.  The 1998
emissions were calculated using a database purchased by EPA from the
Conservation Technology Information Center at Purdue University which
contained county level data on the number of acres planted by type of
tilling and crop type.  Data were grown to 2002 using national level
data on the number of acres tilled by tilling type.  2002 emissions from

Rhode Island accepted the inventory that EPA developed for
non-residential construction.  The methodology used is contained in the
Documentation.

Emissions of PM10 and PM2.5 were estimated based on the number of acres
disturbed for construction. The activity data, the annual value of
non-residential construction, was obtained from the US Department of
Commerce Bureau of Census.  The national value was allocated to the
counties using county level non- residential construction employment
data obtained from the Bureau of Labor Statistics and Dunn and
Bradstreet.  To estimate the number of acres disturbed by nonresidential
construction, a conversion factor of 1.55 acres per million dollars was
applied to the county level valuation data.  Non-residential
construction emissions for 2002 for Rhode Island were calculated as
follows:

4.0 Mobile Sources  TC "4.0 Mobile Sources" \f C \l "1"  

The Rhode Island 2002 Periodic Emissions Inventory of Mobile Sources is
divided into five categories: non-road sources, aircraft, commercial
marine vessels, locomotives and on-road vehicles. Emissions were
calculated following the methodologies outlined in  the EPA document
“Procedures for Emissions Inventory Preparation Volume IV, Mobile
Sources ” and  the “Documentation for Aircraft, Commercial Marine
Vessels, Locomotives and other Non-road Components of the National
Emissions Inventory, Volume 1, Methodology,” prepared by EH Pechan and
Associates, September 2005.  These documents provided guidance on how to
identify sources, estimate emissions and establish a mobile source
emissions inventory.     

4.1 Non-Road Sources  TC "4.1 Non-Road Sources" \f C \l "2"   

Emissions from non-road engines were calculated using the EPA Nonroad
Emission model, core model version 2005a, February 2006 The recently
revised non-road model predicts emissions generated from more than 80
basic and 260 specific types of equipment. Typically equipment in this
category includes recreational vehicles, logging equipment, tractors,
construction equipment, residential/commercial lawn garden and water
pleasure craft. The model does not predict emissions from commercial
marine vessels, locomotives or aircraft.    Emissions from airport
ground service equipment are included in the aircraft section of this
report. 

Default values for year 2002 used in the model include RFG –Phase 2;
RVP –6.8; oxygen 2.0%; gasoline sulfur 0.030%; diesel sulfur 0.33%;
stage two control 85%; min temp 60 F; max temp 88 F; avg temp 75F.2

The ammonia emissions (NH3) were calculated by obtaining the diesel fuel
and gasoline consumption quantity generated from the non-road model for
year 2002. Using an emission factor of 83.3 mg/gal for diesel fuel and
116 mg/gal for gasoline fuel then adding together results yields the
ton/year emission. An example calculation as follows:

 Statewide: gasoline fuel use 17,535,720 gallons/year x 116 mg/gal- NH3
/1000   mg/gm / 454 gm/lb / 2000 lb/ton = 2.2 ton/yr 

 diesel fuel use 19,610,415 gallons/year x 83.3 mg/gal- NH3 /1000  
mg/gm / 454 gm/lb / 2000 lb/ton = 1.8 ton/yr 

Total NH3 Emissions 2.2 gasoline + 1.8 diesel = 4.0 tpy

4.2 Aircraft  TC "4.2  Aicraft" \f C \l "2"  

Aircraft emissions were obtained from a report prepared for the Rhode
Island Airport Corporation (RIAC) entitled  “Air Pollutant Emissions
Inventories for Block Island State Airport, Newport State Airport, North
Central State Airport, Quonset State Airport, TF Green State Airport,
and Westerly State Airport” prepared by KB Environmental Services and
Vanasse Hangen Bruslin Inc.  The purpose of the report was to document
the emissions associated with the six airports and provide accurate data
to RI DEM for incorporation into the SIP.   The report included the
emissions expected from the aircraft as well as the ground support
equipment for each of the 6 airports.  The report is attached in
Attachment  A.

The emissions inventory was developed using the Federal Aviation
Administration (FAA) Emissions and Dispersion Modeling System (version
4.5) (EDMS) as recommended by EPA guidelines.  The FAA model contains a
database of aircraft specific emission factors based on engine
manufacturer, model and operational mode.  Landing and Take Off (LTO)
data was obtained from RIAC.

The model allows the user to specify annual temperature, mixing height
and aircraft operational mode times.  The ambient temperature used in
the model was based on the 30-year annual mean temperature in Providence
Rhode Island of 50.4 degrees Fahrenheit.  A mixing height of 2,226 feet
was used, which is consistent with average afternoon conditions and is
based on the most recent five years of meteorological data from
Providence, Rhode Island and Chatham, Massachusetts.  Aircraft
operational times for takeoff, climbout and approach were based on EDMS
default operating times.  For Block Island, Newport, North Central,
Quonset and Westerly state airport, the EDMS default taxi/idle and
ground delay times were used.  For TF Green Airport, operational data
developed for the draft Environmental Impact Statement air quality
assessment for the proposed runway extension was used.   

To estimate pounds emitted per summer day, the model was run using
actual LTO data.   

Emissions from the 6 airports are summarized below.

4.3 Commercial Vessels  TC "4.3 Commercial Vessels" \f C \l "1"   

Emissions for commercial vessels were calculated using the fuel sales
methodology described in EPA’s “Procedures for Emissions Inventory
Preparation Volume IV, Mobile Sources (July, 1989).” The amount of
residual and distillate fuel used for vessel bunkering in 2002 was
obtained from the Department of Energy’s “Energy Information
Administration Fuel Oil and Kerosene Sales Report, 2002”.  In 2002,
only distillate fuel was used.  9,002,000 gallons were reported for
vessel bunkering.

It was assumed, consistent with the mobile source guidance, that 75% of
the distillate fuel was used in port.  The Port of Providence, located
in Providence County, is the only major port in Rhode Island where
vessel bunkering occurs.

The following emission factors were used:

	lb/103 gal

VOC	50

NOx	270

PM10	40.66

PM2.5	37.4

CO	110

SO2	27

Emissions from distillate fuel used in port were calculated as follows:

9002 * 103 gallons x 0.75 x 50 lbs VOC /103 gallons/ 2000 lbs/ton = 				
		

	169 tons VOC /yr

The number of commercial vessels using Rhode Island ports is considered
to be consistent throughout the year. Emissions for a typical summer day
were calculated by dividing the total emissions for 2002 by 365 days.

4.4 Locomotives  TC "4.4 Locomotives" \f C \l "1"  

Emissions for locomotives were calculated following the methodology
contained in the MARAMA/MANE-VU “Locomotive Mobile Source Category
Calculation Methodology Sheet.”  The methodology requires the amount
of fuel used by locomotives in Rhode Island. Fuel use data were obtained
by contacting the four rail lines that operate in Rhode Island,
Providence & Worcester (P&W), Amtrak, MBTA and Seaview Transportation.

Amtrak operates the commuter rail and Metroliner in Rhode Island with
diesel line haul locomotive engines.  Amtrak/MBTA provided information
that approximately 600,000 gallons of diesel fuel were used in the year
2002. Emissions were apportioned to the counties based on the track
miles in each county.   From Amtrak maps it was determined that there
are 52 miles of track used by Amtrak in Rhode Island.  Of the 52 miles,
10 miles (19.2%) are in Kent County, 18 miles (34.6%) are in Providence
County and 24 miles (46.2%) are in Washington County.  No Amtrak lines
operate in Bristol and Newport Counties.

P&W Railroad, an interstate freight carrier, also operates diesel line
haul locomotives.  P&W estimated that 100,000 gallons of fuel were
consumed during 2002 by locomotives which operated in Rhode Island.  
The emissions from P&W were apportioned to the counties based on the
track miles P&W utilizes in each county.  Based on the information
provided by P&W, P&W uses 83.04 total miles of track in Rhode Island; 12
(14.5%) are in Kent County, 41.24 (49.7%) are in Providence County and
29.8 (35.9%) are in Washington County. The P&W lines in Bristol and
Newport Counties did not operate in 2002.

 

Seaview Transportation is a small switching operation located in Quonset
Point/Davisville Industrial Park, Washington County. They provide goods
to the park tenants using a 23-mile internal rail system owned by the
Rhode Island Economic Development Corporation. All locomotives at this
facility are considered yard locomotives.  During 2002, Seaview used
8,975 gallons of diesel fuel oil. 

For Amtrak, MBTA and P&W, emissions were calculated by multiplying the
amount of fuel consumed by the trains in the State by the appropriate
line haul emission factor.  No seasonal adjustment was used and the
activity was determined to be 260 days/year.

For Seaview Transportation, emissions were calculated by multiplying the
amount of fuel consumed by Seaview by the appropriate yard emission
factor.  No seasonal adjustment was used and the activity was determined
to be 260 days/year.

The following emission factors use in MARAMA’s calculation methodology
sheets were obtained from EPA’s “Emission Factors for Locomotives,
Technical Highlights (December 1997).”

4.5 On-road Mobile Sources  TC "4.5 On-road Mobile Sources" \f C \l "1"
  

On-road mobile source emission factors were generated from EPA’s
MOBILE6.2 model.  The model estimates emission factors in grams per
vehicle mile by vehicle class and vehicle speed.  Rhode Island
Department of Transportation (RI DOT) supplied RI DEM with 2002
seasonally adjusted (July) average daily vehicle miles traveled (DVMT)
data for 8 FHWA roadway classifications.  Those data are derived from
the State’s Highway Performance Monitoring System (HPMS) network.  

The DVMT was apportioned to each roadway classification based on the
number of vehicles in each of the classes.  The Rhode Island Division of
Motor Vehicles (RIDMV) provided RI DEM with a registration distribution.
 EPA reviewed the data provided by RIDMV comparing it to the default
MOBILE6.2 vehicle mix and found that it is appropriate to use Rhode
Island data for heavy-duty gas vehicles and heavy-duty diesel vehicles,
but not for light duty gasoline trucks and light duty gasoline vehicles.
The EPA analysis provided an adjusted DVMT mix for 2002 that was used in
the model. These eight adjusted DVMT fractions were then entered into
the MOBILE6.2 utility program which generated the 16 vehicle
classifications needed for the input file

The following inputs were included in the Rhode Island model run for
typical summer day emissions: Rhode Island  I/M program, Stage II
refueling controls, national LEV credits starting in 1999,  adjusted
registration distribution file,  reformulated fuel program, fuel RVP
6.8, min/max temp 67 & 88 and NLEV program. 

Average vehicle speeds by roadway classification were obtained from the
Rhode Island Statewide Planning Program model. The reported speeds
adjusted to account for the limitations of the MOBILE6.2 model are as
follows:  

Roadway Functional System	Weighted Average Speed	Weighted Average Speed
Rounded

Rural

Interstate	60.7	61

Other principal arterials	59.6	60

Minor arterial	48.7	49

Major collectors	44.1	44

Other freeways/expressways	43.9	44

Other principal arterials	29.6	30

Minor arterial	27.3	27

Collectors	23.1	23

Local	20.0	20

MOBILE6.2 input and output files are attached as Attachment B.  Emission
factors generated from MOBILE6.2 were multiplied by the DVMT for that
roadway classification and vehicle class to determine emissions in grams
per day. The gram per day emissions for the 12 roadway classifications
were then summed and converted to units of pounds per day emissions for
each pollutant.  Emissions for Stage II refueling were zeroed out as
those emissions are accounted for in the non point stationary source
portion of this inventory.  The following is a summary of statewide
on-road emissions:

Pollutant	Emissions (ppsd)

CO	770,280

VOC	64,678

NOx	84,800

PM 2.5 	1,480

PM10 	2,425

SO2	3,081

NH3	5,642

Annual emissions estimates were calculated by the EPA and obtained from
the National Emissions Inventory. Annual emission estimation
methodologies are contained in “Documentation for the Final 2002
Mobile National Emissions Inventory,” September 2005, prepared  by
EPA’s Office of Transportation and Air Quality and EH Pechan and
Associates.  Input files for DVMT, registration distribution, average
speeds, I/M program and Stage 2 refueling program were provided to EPA
for input to the model.  Gasoline properties entered into the model were
determined by the Eastern Research Group (ERG), under contract with EPA.
   Temperatures used in the model were obtained from the National
Climatic Data Center for each county.

DVMT data provided by the RIDOT are statewide.  Emissions were
apportioned to the counties based on population distribution.

5.0  Quality Assurance/Quality Control                                 
                                                                        
                 TC "5.0  QA/QC" \f C \l "1"  

Quality control (QC) is a system of routine technical activities
implemented by inventory development personnel to ensure the quality of
the inventory as it is being developed.  The QC procedures used in the
preparation of this inventory included the use of EPA approved emission
estimation methodologies, technical reviews and data validations.  
These activities were included in inventory development planning, data
collection and analysis, emission calculations and reporting.    

Quality assurance (QA) is a planned system of review and audit
procedures conducted by personnel not actively involved in the inventory
development process.  The key concept of this component is independent,
objective review by a third party to assess the effectiveness of the QC
program and the completeness and accuracy of the inventory.  Due to
limited resources and staff within the Department, a QA program was not
implemented, however QC procedures were followed throughout the
inventory as detailed in this section of the inventory.

 

5.1  Purpose and Intention  TC "5.1  PURPOSE AND INTENTION" \f C \l "1" 
 

The purpose of the emissions inventory is to maintain an accurate record
of point, nonpoint and mobile source air emissions.  The emissions
inventory plays an integral part in the Office’s air quality
improvement programs.  The emissions inventory is used for:

- Enforcing and monitoring compliance with Rhode Island’s air
regulations;

- Supporting other air quality programs;

- Evaluating trends in air quality;

- Supporting the development of the State’s regulations;

- Supplying data for use in air quality models;

- Public information requests

- Compliance demonstrations;

- Operating permit fees

5.2  Roles and Responsibilities  TC "5.2  Roles and Responsibilities" \f
C \l "1"  

Karen Slattery, Principal Air Quality Specialist, coordinated the 2002
Emissions Inventory.  Karen has been involved in inventory development
since 1988.  For the 1990 base year inventory she prepared the nonpoint
and mobile source portions of the report.  For subsequent inventories
she has prepared the point source emissions and reported those data to
EPA for major sources as required by the CERR.  For the 2002 Emissions
Inventory she performed all point source calculations and reviewed
emission estimates supplied by the facilities.  For nonpoint sources she
reviewed emissions estimated prepared by EPA and MARAMA/MANEVU. 
Detailed emissions estimation procedures are contained in the nonpoint
source section.  Karen also reviewed the mobile source section for
completeness and consistency with prior year’s inventory.  She is also
responsible for preparation of the NEI files that are submitted to EPA
via CDX.



Ronald Marcaccio, Senior Air Quality Specialist, has been with the
Office for 27 years.  He has worked in the mobile source section for 8
years and prior to that worked as an air permit engineer and air
inspector.  He was responsible for the preparation of the on-road and
non-road mobile source inventory.   He works closely with the Rhode
Island Department of Transportation and the Department of
Administration’s Division of Motor Vehicles to assure the mobile
source data are as reasonable and accurate as possible.

Jean Glanville, Environmental Quality Technician has been with the
agency for 20 years.  She has worked on the inventory for 8 years.  Her
primary responsibilities include calculation of emissions from small
point sources and mailing out of the annual emissions inventory.  In her
review of the small sources she determines if any source could
potentially be a point source and refers potential point sources to
Karen Slattery for further review.

Paige Albro, data entry clerk, has been with the agency for 2 years. 
Her role in the inventory includes entry of all calculated emissions
data into the state database and logging in the forms as they are
received from the sources.

Barbara Morin, Supervising Environmental Scientist reviewed the
inventory report for completeness and consistency.  

The enforcement section of the Office of Air Resources routinely
inspects Title V sources for permit compliance.  During these
inspections, staff engineers check for gross errors and omissions in the
inventory reported.  Any discrepancies they find are reported to Karen
Slattery for further investigation.

5.3  Point Sources  TC "5.3  Point Sources" \f C \l "1"  : 

 Point source data collection activities for the 2002 base year
inventory began in January 2003.  An existing point source emission
inventory, compiled for the 1990 base year and subsequently used to
develop 1996 and 1999 projection inventories, formed the starting point
for the point source list.  The inventory list is updated annually using
information obtained from permit files, internet searches and local
telephone directories.   Potential point sources identified by staff
engineers during inspections were also added.   Manufacturing sources
known to use criteria or hazardous air pollutants and sources known to
be major fuel users are included in the inventory.  In total 600 sources
were inventoried for the 2002 base year inventory.

Rhode Island’s 2002 Point Source Inventory mailing was initially sent
out in February 2003.  Forms were due April 15, 2003, and those sources
that had not returned their forms by that date were sent a second set of
forms with a Letter of Noncompliance.  All facilities whose forms were
returned to the office by the US Postal Service marked undeliverable
were contacted to verify mailing address.  If the telephone number was
no longer valid the source was removed from the inventory and assumed to
be no longer operating.  Approximately 85 facilities did not return the
inventory survey forms.  Based on the type of industry and the number of
employees at these sources, it was determined that the sources that did
not return the forms would not have met the thresholds to be considered
point sources.  Emissions from these sources are accounted for in the
nonpoint source portion of the inventory.

After the survey forms were received by the Office they were logged into
the Department database and filed as either a point source or small
source.  For the point sources, emission statements were reviewed to
ensure that the correct emission factors were used, that correct mass
balance calculations were performed and that assumptions made based on
process knowledge were reasonable.  In several cases, follow-up
telephone calls were made to ensure the accuracy of the data.  After the
emissions estimates were reviewed, they were compared to the estimates
for the previous year for data consistency.   If there were any large
discrepancies, the company was contacted to verify the emissions.

After verifying the data for each facility, the emissions of criteria
and toxic air pollutants were entered into the Department database by
SCC process.  The data from the State database was then used to develop
NEI version 3 input files.  These files were uploaded into the EPA
system using CDX.  These data were extracted and summarized by the EPA
and MARAMA/MANE-VU contractor EH Pechan and Associates and sent to the
State for review.  Any discrepancies were resolved. 

5.4  Nonpoint Sources:  TC "5.4  Nonpoint Sources:" \f C \l "1"    

Due to staff limitations, the nonpoint inventory was largely developed
using emission estimates prepared by EPA and MARAMA/MANE-VU.   For
residential wood combustion, residential open burning, industrial
refrigeration, POTWs (NH3) and composting activities (NH3 and VOC), EH
Pechan and Associates, under contract with MARAMA/MANE-VU, developed
emissions inventory estimates.   Rhode Island participated in several
workgroup conference calls concerning the development of those emissions
estimates and accepted them for use in the 2002 emissions inventory.  QA
procedures for those emissions estimates are specified in the reports
prepared by Pechan.

For cutback asphalt and dry cleaning, State inventory data were
substituted for EPA data as the state had more accurate emissions
estimates based on data supplied by the facilities.  The cutback asphalt
data were provided by Hudson Asphalts, the sole provider in Rhode
Island.  After emissions estimates were prepared, that section of the
report was sent to Hudson for review.  Dry cleaning data were compared
to the previous year’s data for consistency.  

NEI files prepared by EPA were reviewed and edited as necessary to
reflect the correct data for RI.  The files were submitted to EPA via
CDX.   The EPA contractor EH Pechan and Associates reviewed the file and
data issues were identified which were corrected by the state. 



5.5   On-Road Mobile Sources  TC "5.5   On-Road Mobile Sources" \f C \l
"1"  

On-road mobile source emission factors were generated from EPA’s
MOBILE6.2 model.  Rhode Island Department of Transportation (RI DOT)
supplied RI DEM with 2002 seasonally adjusted (July) average daily
vehicle miles traveled (DVMT) data for 8 FHWA roadway classifications.  
The DVMT was apportioned to each roadway classification based on the
number of vehicles in each of the classes.  The Rhode Island Division of
Motor Vehicles (RIDMV) provided RI DEM with a registration distribution.
 EPA reviewed the data provided by RIDMV comparing it to the default
MOBILE6.2 vehicle mix and found that it is appropriate to use Rhode
Island data for heavy-duty gas vehicles and heavy-duty diesel vehicles,
but not for light duty gasoline trucks and light duty gasoline vehicles.
The EPA analysis provided an adjusted DVMT mix for 2002 that was used in
the model. These eight adjusted DVMT fractions were then entered into
the MOBILE6.2 utility program which generated the 16 vehicle
classifications needed for the input file

Average vehicle speeds by roadway classification were obtained from the
Rhode Island Statewide Planning Program model and are consistent with
previous emission inventories.

Annual emissions estimates were calculated by EPA and obtained from the
National Emissions Inventory.  Input files for DVMT, registration
distribution, average speeds, the I/M program and the Stage II refueling
program were provided to EPA for input to the model.  Gasoline
properties entered into the model were determined by the Eastern
Research Group (ERG), under contract with EPA.    Temperatures used in
the model were obtained from the National Climatic Data Center for each
county.  EPA generated emissions files from that which were uploaded to
the NEI.

5.6  Non-Road Mobile Sources  TC "5.6  Non-Road Mobile Sources" \f C \l
"1"  :

Non-road emissions are prepared for various categories of small engines
and aircraft, locomotives, and marine engines.  The emissions are
prepared for small engines by use of EPA’s NONROAD Model.  In running
the model the user must specify a modeling scenario by the inventory
year, geographic region (nation, state, county), time period (annual,
seasonal, monthly, daily) and the equipment categories.  For all other
required variables, the NONROAD model provides default input values.   
In reviewing the defaults it was noted that the default value for
pleasure craft was lower than the registration data obtained from the
RIDEM’s Office of Boating and Safety.  The number of additional
vessels was incorporated into the models vessel inventory population
file.   The NONROAD model was run without error and the emissions files
generated were uploaded to the NEI using CDX.

Locomotive and marine emissions estimates were prepared in accordance
with methodology in EPA’s Procedures for Emission Inventory
Preparation, Volume IV: Mobile Sources.  Draft emissions calculations
were reviewed by Karen Slattery and changes were made to locomotive
emission factors based on newer factors obtained from EPA’s
“Documentation for Aircraft, Commercial Marine Vessel, Locomotive and
Other Nonroad Components of the National Emissions Inventory,”
September 30, 2005 and the MARAMA/MANE-VU “Locomotive Mobile Source
Category Calculation Methodology Sheet. ” .  

The draft 2002 inventory submitted earlier to the EPA for review
contained commercial aircraft emissions calculated using an aircraft
emissions model developed by for the Northeast Sates for Coordinated Air
Use Management (NESCAUM) with LTO data obtained from RIAC

After submitting the draft inventory, a detailed report of Rhode Island
airport emissions was prepared by KB Environmental Services  and Vanasse
Hangen Bruslin Inc for RIAC.  The report contained more detailed
information on LTO’s by aircraft type than submitted in the draft
inventory.  The final inventory has been updated to reflect these data. 
The FAA database was used to calculate emissions in the study consistent
with EPA Mobile guidance.  

Non-road data were compiled for EPA in NEI Version 3 format.
