1.0 INTRODUCTION
1.1 Background
Under the Clean Air Act Amendments (CAAA) of 199 0, the
requirements of Title I continue and embellish many of the
programs of EPA's previously proposed Post-1987 Policy for State
Implementation Plans (SIPs). States will have the responsibility
to inventory emissions contributing to National Ambient Air
Quality Standards (NAAQS) nonattainment, including ozone and
carbon monoxide (CO). The CAAA establish nonattainment area
classifications and inventory requirements ranked according to
the severity of the area's air pollution problem. For ozone
there are five nonattainment classifications identified as
Marginal, Moderate, Serious, Severe, and Extreme. Two
classifications are given for CO nonattainment areas, Moderate
and Serious. Starting with a base year inventory in 1990, States
will be required to track these emissions over time and ensure
that control strategies are being implemented that reduce
emissions and move areas toward attainment.
States will be able to compile 1990 base year inventories
using much of the procedural guidance issued in connection with
the proposed Post-1987 Policy. One significant change is a new
requirement for ozone nonattainment inventories to include
biogenic emissions. Additionally, States will be required to use
EPA's revised mobile source emissions factor model, MOBILE4.1
(California may continue to use the EMFAC model). Base year
inventories developed and submitted under the 1990 CAAA will also
be required to conform to more standardized and rigorous
reporting and documentation provisions than previous inventories.
All ozone/CO inventory data submitted to EPA under 1990 CAAA
requirements must be in an Aerometric Information Retrieval
System (AIRS)-compatible format before final approval of the SIP
is given. However, EPA will allow States the option to use
current SIP Air Pollutant Inventory Management System (SAMS) PC
packages to collect point source data until this information can
-------
be transferred to the AIRS format according to EPA guidance
procedures. Point source data transfer from the SAMS PC package
to the AIRS Facility Subsystem (AFS) is scheduled to begin in
January 1992.
EPA must promulgate final nonattainment designations for
areas under the NAAQS program by July 13, 1991. Based on a
nonattainment area's classification, the CAAA require additional
inventories to be prepared, beyond the base year 1990 inventory.
For ozone nonattainment areas there are four possible
inventories: a base year inventory; a periodic inventory; a
reasonable further progress projection inventory; and a modeling
inventory. For CO nonattainment areas, there are three types of
inventories: a base year inventory; a periodic inventory; and a
modeling inventory. With both ozone and CO nonattainment areas,
the base year inventory is the primary inventory from which all
of the others are derived.
To assist States with the preparation of base year
inventories, the EPA has developed a large complement of
inventory guidance materials. A listing of the guidance
materials published for preparing the 1990 baseyear.inventory is
given in Table 1-1. With dozens of inventories being prepared
all across the country, the EPA is concerned about consistency,
quality, and adherence to the published guidance. To this end,
this document has been developed to serve as a common basis for
quality review of revised SIP inventories in all ten EPA regions.
1.2 Purpose of Document
The primary purpose of this document is to provide a
standard set of guidelines to use in conducting formal reviews of
1990 base year SIP inventories received from ozone and CO
nonattainment areas. Having a standard set of inventory review
guidelines will help ensure national consistency in the level of
scrutiny that submitted inventories will undergo. These
guidelines will also ensure the proper documentation of review

activities to allow for serial review with minimal overlap. A
third use of this document and the review guidelines is to
provide State agencies preparing the inventories with information
to use as a self-check prior to submitting the inventories to
EPA.
This document provides review guidelines that address
whether States followed the overall requirements for base year
inventory preparation published in the guidance material shown in
Table 1-1 and whether the inventories meet developed
specifications for completeness, consistency both internal and
with national trends), reasonableness of emission values, and
overall documentation requirements. The review guidelines given
in this document are not meant to be used to determine the
absolute accuracy of an inventory or whether values are "right or
wrong." Similarly, a "no" answer to a checklist question does
not necessarily mean that an item is deficient (e.g., there may
have been an alternate approach used that may be acceptable if
properly justified). Instead, the guidelines should serve as a
mechanism for identifying areas of incomplete emissions data,
inadequate documentation, or potential errors, and for
determining if the recommended procedural elements were included.
The guidelines will also promote timely feedback to the preparing
agency on ways they need to revamp their inventory to be
acceptable for the purposes of 1990 base year inventories.
Two levels of review have been designed and are presented in
this document. The document contains a set of model forms and
review checklists in Appendices A, B, and C that expedite the
review processes. The model forms may be adapted to meet the
needs and requirements of the reviewing agency. The review
checklists may be copied and used as often as necessary.
Instructions for completing the checklist in Appendix A are
given in Sections 3 and 4. This draft of the guidance document
does not contain specific instructions for the CO nonattainment
inventory review. However, where many of the checklist items in
tls.023
1-5
-------
Appendix B are the same as or similar to items in the ozone
review checklist, the same instructions would apply. Appendix C
provides a detailed review checklist for on-road mobile sources
that supplements the review questions found in Appendices A and
B. A more detailed description of the two levels of review and
the overall intended review process is given in Section 2.
tls.023

-------
2.0 OVERVIEW OF INVENTORY GUIDELINES
The quality review program for 1990 base year emission
inventories presented in this document contains two levels of
review known as Level I and Level II. The Level II review is
significantly more detailed and specific than the Level I review
and should be performed after the Level I review is completed.
There are, for example, questions in Level I that if answered
negatively would require the reviewing agency to send the
inventory back to the preparers for revision before further
review could be performed. Failure to meet minimum standards set
forth in Level I would dictate that Level II should not even be
attempted.
Level I is intended to be a global check of the inventory to
ensure that it meets the minimum requirements and quality
standards set forth in the guidance documents Emission Inventory
Requirements for Ozone State Implementation Plans
(EPA-450/4-91-010) and Emission Inventory Requirements for Carbon
Monoxide State Implementation Plans. (EPA-450/4-91-011).
Purposes of the Level I checks include:
ensuring that the whole inventory was prepared
according to the specified procedures (e.g., seasonal
adjustment, rule effectiveness) and that all essential
data elements (e.g., point, area, and mobile sources,
VOC, NOx, and CO emissions) are present,
flagging obvious omissions for the purpose of providing
immediate feedback to the preparing agency, and
providing the basis for making decisions regarding
whether or not inventory review should continue in the
event that problems are discovered.
tls.023
2-1
-------
Level I is explained in detail in Section 3 as is the guidance
for using the Level I checklists. The complete Level I
checklists for ozone and CO nonattainment inventories are given
in Appendix A , Table A-l and Appendix B, Table B-l,
respectively.
The Level II quality review process is much more detailed
and specific than Level I. Its purpose is to check the inventory
with respect to completeness of source coverage, the correct
application of procedural requirements, and overall consistency
both within the inventory and with nationally-based
representative values. The consistency checks in Level II
provide only a relative measure of accuracy for values and do not
necessarily show whether a value is correct or not. Level II
checks have been developed for stationary point sources,
stationary area sources, area on-road mobile sources, and area
non-road mobile sources. Detailed descriptions of the Level II
checks for these sources can be found in Section 4. The Level II
checklists are contained in Appendices A and B, with Table A-2
for ozone nonattainment inventories and Table B-2 for CO
nonattainment inventories.
Special attention should be paid to the first three forms in
Appendices A and B. These forms are part of the review package
but are not part of either the Level I or Level II checklists.
These forms are more administrative in nature in terms of
properly identifying the inventory and documenting how the
quality review was performed. Forms A-l or B-l should be filled
out for each applicable ozone or CO nonattainment inventory that
is submitted.
Forms A-2 and B-2 document the quality review process
carried out at the EPA Regional Office level for ozone and CO
nonattainment inventories. It records the original receipt of
the inventory and chronicles who reviewed it, when they reviewed
it, and what parts were reviewed. Forms A-3 and B-3 are used to
provide a record of the correspondence between the Regional
-------
Office and the States on discussions relating to inventory
preparation and quality. Forms A-3 and B-3 only require that a
copy of all such correspondence be attached as a part of the
quality review package.
A detailed review checklist of on-road mobile sources has
been prepared by EPA's Office of Mobile Sources and is found in
Appendix C. This checklist provides specific review questions
concerning vehicle miles travelled (VMT) estimates and emission
factor calculations for on-road mobile sources. Review questions
cover the use of MOBILE4.1 and the Urban Transportation Planning
System (or similar transportation planning models) in developing
emissions data for this category. An additional checklist of
off-road mobile sources is being prepared by the Office of Mobile
Sources and will be provided as a supplement to this document at
a later date.
Section 5 of this report discusses how the entire inventory
review process should be summarized and follow-up activities that
should occur. It describes what activities should take place
once an Appendix A or B checklist package has been completed.
Essentially, the Regional Office should transmit the completed
package back to the submitting agency and supply them with a
write-up describing all inventory deficiencies. To complement
the summarization discussion, Section 5 also contains an example
of a review summary transmittal memo that can be used to debrief
States on the Regional Office's comments regarding inventory
adequacy.

3.0 LEVEL I REVIEW
3.1 Introduction
The purpose of this section is to define Level I quality
review as it pertains to 1990 base year inventories and describe
the kinds of specific data quality checks it entails. Level I is
essentially the initial level of broad review that should be
performed on ozone and CO nonattainment inventories. Level I
checks parallel the inventory preparation guidance requirements
found in the reports Emission Inventory Requirements for Ozone
State Implementation Plans (EPA-450/4-91-010) and Emission
Invent rv Requirements for Carbon Monoxide State Implementation
Plans (EPA-450/4-91-011). The questions found in the Level I
checklists in Appendix A, Table A-l and Appendix B, Table B-l are
designed to quickly and easily allow a determination to be made
as to whether the basic inventory requirements specified by EPA
have been met.
The Level I checks also have the purpose of serving as a way
to flag obvious omissions such that immediate feedback can be
provided to the preparing agency. The checklist can be used as a
decision tool to determine whether an inventory contains
sufficient information to warrant going through the entire review
procedure. The Level I process may uncover inventory flaws that
make continuing with the review process an unproductive venture.
Flagging such flaws early helps get the inventory back into the
preparer's hands for revision.
Level I ensures that the key "big picture" inventory items
have been satisfactorily addressed before more detailed review
takes place in Level II. For example, it addresses such items as
inclusion of point, area, and mobile sources; VOC, N0X, and CO
emission estimates; clear definition of the geographic area of
the inventory; key procedural requirements such as rule
tls.023 _
-------
effectiveness and ozone season adjustment; and performance of
quality assurance measures. Level I review is not a measure of
whether a specific number is right or wrong.
The remainder of this section provides a set of detailed
instructions for inventory reviewers to follow in using the
Level I checklist found in Appendix A. In addition to the
instructions, a copy of the associated checklist sections are
also provided for clarification purposes and to avoid having to
jump back and forth between Section 3.0 and Appendix A when
reading the instructions.
3.2 Instructions for Completing Level I Review Checklist for
Ozone Nonattainment Inventories
This section contains detailed instructions for completing
the Level I Review Checklist in Appendix A, Table A-l. The
instructions are keyed to the checklist numbering system found in
the appendix. The instructions contain text describing how to
use the checklist, tables with examples of the kinds of
information the reviewer should be looking for in the inventory,
and a copy of the actual checklist sections being described to
give the reviewer a quick reference tool as they are reading the
instructions. If the guidelines in the instructions are not met
by the inventory, the box for that question should be checked
"No. "

1.1.2 The inventory should indicate the correct
classification for the nonattainment area (marginal,
moderate, serious, severe, or extreme).
1.1.3 Each nonattainment area contains a certain number of
affected counties. The counties in the nonattainment
area that are addressed in the inventory should be
clearly identified. The reviewer should be aware than
an inventory may contain only parts (i.e., towns,
cities) of a county, which together comprise the entire
nonattainment area. In this case, the inventory should
still include emission summaries on a county-specific
basis, even if the entire county is not represented.
This will allow designated nonattainment areas to be
more clearly evaluated for tracking purposes.
1.1.4 The guidelines for SIP nonattainment base year
inventories requires that all 100 ton/yr emission
sources found in the geographic area extending 2 5 miles
out from the boundary of the designated nonattainment
area be included in the base year inventory. The
25-mile zone should be defined in some way either
descriptively or by the use of a map.
1.1.5 The inventory should address VOC, NOx, and CO
emissions. If any one of the three is not included for
a source type where it is applicable (e.g., NOx from
mobile sources was not covered), the box should be
checked "No." Table 3-1 should serve as an aid in
determining which pollutants are associated with what
categories.

Emissions from these sources may occur from source categories identified elsewhere in Table 3-2. For
example, carbon monoxide and oxides of nitrogen are emitted from industrial boilers at organic inorganic
manufacturing facilities. Likewise, carbon monoxide and oxides of nitrogen are emitted from reciprocating
engines at oil and gas production facilities, and volatile organic compounds are emitted from many
industries involved in degreasing operations. An effort should be made to avoid double counting from these
sources.

1.1.10 For each pollutant, the reviewer is asked to calculate
the percent contribution to emissions from each of the
four major source types: stationary point sources
(SPS), stationary area sources (SAS), on-road mobile
area sources (OMAS), and non-road mobile area sources
(NMAS). Enter the percent contributions on the lines
provided. The percentages should be for the total area
included in the inventory and not individual counties.
1.1.11 The reviewer should check the emission estimates and
the calculations to verify that emissions are specific
to the ozone season and that daily activity has been
incorporated into the estimate. Examples of seasonal
adjustment factors for area sources are given in
Table 3-3.
1.1.12 The reviewer should check the inventory and the
documentation to ensure that non-reactive VOC have not
been included in the VOC emission totals. Non-reactive
VOC are not allowed to be counted as VOC for the
purposes of SIP ozone nonattainment inventories. The
list of non-reactive VOC is given in Table 3-4.

1.1.13 The emission inventory estimates should have been
determined by taking into account existing regulatory
requirements. For the purposes of Level I, the
reviewer should check that the inventory documentation
acknowledges the use of existing regulatory
requirements, and follow up with a more complete review
of calculations in Level II. Examples of the types of
regulations that should have been included are given in
Table 3-5.
1.1.14 The reviewer should check the inventory documentation
to make sure that rule effectiveness and rule
penetration were incorporated where applicable. These
conditions are applicable for any source category that
has existing regulatory requirements on it to reduce
emissions and that is not an uncontrolled sources. For
the purposes of Level I, the reviewer should check that
the documentation in general shows that rule
effectiveness was used where applicable, and follow up
with a more complete review of calculations in
Level II. In cases where rule effectiveness was
applied, the reviewer should check to see if an
effectiveness level other than the 80 percent EPA

1.2 POINT SOURCES
1.2.1 Emission estimates should have been developed for all
VOC point sources with actual emissions of at least
10 tons/yr. The reviewer should check the inventory
documentation to determine how point sources were
identified for inclusion in the inventory. Source
types such as those shown in Table 3-6 would need to
have been evaluated for inclusion in the inventory.
The method of source identification should be
delineated as a part of the documentation.
Identification methods might include: 1) existing State
permit files, 2) NEDS source listings, 3)NAPAP source
listings, 4) industrial directory listings, 5) existing
SIP inventory listings, and 6) source survey results.
1.2.2 For point sources with VOC emissions egual to or
greater than 10 tons/yr, the inventory should contain
process, point, and segment level data. The parameters
represented by these three data types are shown in
Table 3-7. The parameters required for SIP inventories
are noted.
1.2.3 The reviewer should check to see that 100 ton/yr VOC
emission sources in the 25-mile zone extending out from
the nonattainment area have been addressed in the
inventory. These sources should all be in the
inventory and should have process, point, and segment
level data requirements met as shown in Table 3-8.

Documentation should be present in the inventory
describing why missing categories were not included.
1.3.2 The reviewer should evaluate the documentation for the
area source emissions estimates and ensure that at a
minimum all emission factors and activity levels used
are presented and the sources of these data are given.
If equations are used (e.g., for storage tanks), the
values of all variables, the sources of the values, and
any other assumptions used should be presented. If
sufficient information is not given to independently
replicate the emissions estimates, then documentation
is not sufficient and "No" should be checked.

1.3.3 The reviewer should check to ensure that point source
contributions have been subtracted out from area source
category totals whenever appropriate. Some area source
categories, such as graphic arts, contain both area and
point sources. Large operations are treated as point
sources and are handled in the point source component
of the inventory. However, the mechanism for calcu-
lating area source emissions involves looking at the
entire category, including the point source component.
To avoid double counting, the point source contribution
has to be subtracted out. The categories most likely
to have a point source contribution are degreasing,
graphic arts, drycleaning, and surface coating.
1.3.4 The reviewer should check the inventory documentation
and calculations to make sure that rule effectiveness
and rule penetration were incorporated where
applicable. These conditions are applicable for any
source category that has existing regulatory
requirements on it to reduce emissions and that is not
an uncontrolled source. In cases where rule
effectiveness was applied, the reviewer should check to
see if an effectiveness level other than the 80 percent
EPA default was used. If so, documentation should be
provided for the alternative level used, in accordance
with EPA guidance contained in Procedures for the
Preparation of Emission Inventories for Carbon Monoxide
and Precursors of Ozone. May 1991.
1.4 MOBILE SOURCES
1.4.1 The reviewer should check to ensure that all of the
eight highway vehicle classes shown in the checklist
have been addressed for all counties in the inventory.
Failure to address any category without sufficient
documentation should result in that category being
answered "No."

1.4.2 The reviewer should determine if EPA's M0BILE4.1 model
was used to generate VOC, N0X, and CO emission factors
for on-road vehicle emissions estimates. The
California Air Resources Board has developed a model
called EMFAC7D that is more specific to California.
The model, however, requires more detailed and site-
specific information and, therefore, M0BILE4.1 may have
been used even for California areas. If MOBILE4.1 was
used in an area, including California, answer the
question "Yes." If EMFAC7D was used in California
areas, answer the question "No" and note in the
Comments field what model was used.
1.4.3 If M0BILE4.l was used to estimate on-road vehicle
emissions, the reviewer should check the inventory
documentation to verify that the methods by which the
model was used to determine emissions are explained.
1.4.4 If M0BILE4.1 was used, the reviewer should examine the
inventory documentation for the modeling exercise to
determine if the source of information for the key
model inputs listed are explained. If the source of
the value used for the listed parameter is not
explained, the question for that parameter should be
answered "No."
1.4.5 If a procedure other than the MOBILE4.1 model was used
to generate on-road vehicle emission factors, the
reviewer must determine if this alternative procedure
has been documented in the inventory such that the data
could be replicated by independent reviewers. If
replication is not possible then the question should be
answered "No."

applied, the question should be answered "No."
(California may continue to use the EMFAC model)
1.4.10 If the answer to question 1.4.9 was "No," the reviewer
should check the level of documentation of the
procedure used by ensuring that the parameters in the

4.0 LEVEL II REVIEW
4.1 INTRODUCTION
The purpose of this section is to define Level II quality
review procedures for evaluating the emission inventory for each
of the four general source types: stationary point sources,
stationary area sources, on-road mobile area sources, and non-
road mobile area sources. The Level II review is presented in a
checklist format and addresses completeness, procedures and
consistency for each of the source types in the inventory. Since
many of the review checks in Level II expand on items from the
Level I review, the reviewer should have completed the entire
Level I review before proceeding. Blank checklists for use in
performing and documenting the Level II quality review are
included in Appendix A, Table A-2 and Appendix B, Table B-2. The
remainder of this section presents detailed instructions on how
to use the checklists in performing a Level II review.
4.2 INSTRUCTIONS FOR COMPLETING LEVEL II CHECKLIST - OZONE
NONATTAINMENT INVENTORIES
This section contains detailed instructions for completing
the Level II review checklist in Appendix A, Table A-2. The
instructions are keyed to the checklist numbering system found in
the appendix. The instructions contain text describing how to
use the checklist, and a copy of the actual checklist sections
being described to give the reviewer a quick reference tool as
they are reading the instructions. If the guidelines in the
instructions are not met by the inventory, or if documentation is
insufficient to determine if guidelines were met, the box for
that question should be checked "No".
Reviewers should utilize the comment column to describe
specific findings or to qualify their summary findings as deemed

necessary. If additional comment space is required, reviewers
should attach pages as necessary. The reviewer should also
utilize the checklist comment column to list the location (i.e.,
page number.(s)) in the inventory document where a particular item
is found or discussed. This page number accounting is important
for two reasons: 1) follow-up comments directed to the preparing
agency should be page number specific, and 2) successive reviews
performed by EPA can benefit by avoiding duplicative review
efforts necessary to find the specific item in question.

4.3 STATIONARY POINT SOURCE
Table A-2. Level II Quality Review Checklist
Question Instructions
2.1 COMPLETENESS CHECKS - POINT SOURCES
2.1.1 The inventory should include point sources of 10 ty of
greater. Previously, sources that had VOC emissions in
the range of 10 to 25 tons/yr could be inventoried by
extrapolating the results of a limited survey of
sources in the category to the entire category. Such
extrapolations are no longer allowed. Each individual
VOC source down to 10 tons/yr must be inventoried
separately.
2.1.2 Check the point source documentation to ensure that the
listed small emission source types are represented.
Point sources in the listed categories are expected to
be present in all inventory areas. If one or more of
the categories are not represented, review the
inventory documentation and describe applicable
explanations in the comment column.
2.1.3 A typical inventory area is expected to contain point
sources in each of the listed categories.

necessarily present in all inventory areas, but are
expected to be common in many areas.
2.2 PROCEDURES CHECKS - POINT SOURCES
2.2.1 Review the inventory submittal and determine if
documentation was provided to identify the methodology
used for arriving at the point source inventory.
Briefly describe the approach in the comment column of
the checklist (e.g., based on existing Post-1987
inventory updated to eliminate facilities that have
closed, and updated emissions and production data
through permits, quarterly reports, and plant
contacts). In the checklist comment column, identify
the inventory document page number(s) where the
requested information is found.
2.2.2 The point source inventory should reflect a 1990 base
year. If a previous inventory was used as a starting
point, documentation should be provided to describe how
the previous inventory was adjusted to reflect the 1990
base year.

adjusted to reflect the ozone season and rule
effectiveness. Ozone season adjustments should be
based on point source operating schedules and quarterly
process throughput information. Ozone season
adjustments should be applied on a production unit
level. Emissions should be presented as ozone season
daily emissions. Rule effectiveness should be applied
to all sources that are subject to SIP regulations
(with minor exceptions as noted in Procedures for
Estimating and Applying Rule Effectiveness in Post-1987
Base Year Inventories for Ozone and Carbon Monoxide
State Implementation Plans June 1989).
2.2.4 The inventory documentation should define the month(s)
that were assumed to reflect the ozone season for the
inventory area. In the checklist comment column, list
the period identified as the ozone season and list the
page number of the documentation where the ozone season
determination is described.
2.2.5 states submitting point source inventories can choose
one of four basic options to submit their data: SAMS
Version 3.1, SAMS Version 4.0, AFS Batch Transaction
Format, or interactive direct entry to AFS. If States
chose to use SAMS in submitting their data, they should

2.6 CONSISTENCY CHECKS - AREA SOURCES
The following consistency checks are included to
provide some overall guidance for assessing the
internal consistency and the relative accuracy of an
inventory with respect to other inventories. The
ranges that are provided were developed from a national
perspective and may not necessarily reflect conditions
at any given location. The reviewer will have to
perform some calculations to derive the comparison
indices. All calculated indices should be reported in
the comment column. Emission factors that do not fall
in the listed ranges are not necessarily wrong but do
warrant closer scrutiny.
2.6.1 Using population data and annual VOC emission estimates
for gasoline tank truck unloading for the inventory
area, express VOC emissions on a per capita basis.
Report the per capita factor in the comment column,
determine if the value falls within the defined range,

4.5 AREA ON-ROAD MOBILE SOURCES
The completeness and procedural checks for area on-road
mobile sources focus primarily on the usage of MOBILE4.1 and
how input parameters for the model were derived. The
consistency checks represent nationally-based comparison
values for the key mobile source parameters such as vehicle
miles travelled (VMT), speed, and temperature.
Table A-2. Level II Quality Review Checklist
Question Instructions
2.7 COMPLETENESS CHECKS - AREA ON-ROAD MOBILE SOURCES
If the MOBILE4.1 model was used to determine mobile
source emissions, the reviewer should check to make
sure that all input parameters have been documented.
For several inputs, the guidance manual for using the
model recommends that the user apply a MOBILE4.1
default value instead of trying to develop local data.
For all cases where local data were used and not
M0BILE4.1 defaults, the reviewer should make sure that
documentation has been provided for the
alternative data.
2.8 PROCEDURES CHECKS- AREA ON-ROAD MOBILE SOURCES
2.8.1 The reviewer should examine the M0BILE4.1 documentation
and determine if M0BILE4.1 default values for tampering
rates were used to run the model or was site-specific
tampering information used.

2.8.2 If Question 2.8.1 is answered "No," the reviewer should
check to ensure that the alternative tampering rate
data were reviewed and approved for use by EPA. The
documentation for the M0BILE4.1 runs should describe
the basis and source of the rates and if EPA has
approved them for use in M0BILE4.1.
2.8.3 The documentation for the mobile source inventory
should contain VMT estimates for each county in the
inventory area by vehicle class and road type. The
eight highway vehicle classes are:
- light-duty gasoline vehicles (LDGV)
- light-duty gasoline trucks up to 6000 lbs
(LDGT1)
- light-duty gasoline trucks from 6000-8500 lbs
(LDGT2)
- heavy-duty gasoline vehicles (HDGV)
- light-duty diesel vehicles (LDDV)
- light-duty diesel trucks (LDDT)
- heavy-duty diesel vehicles (HDDV)
- motorcycles (MC)
The road types are as follows:
Rural
interstate
other principal
arterial
minor arterial
major collector

If VMT data are missing for any vehicle class or road
type, answer the question "No," unless the
documentation clearly shows that certain vehicle
classes or road types were not applicable to the
inventory area.

2.8.4 The reviewer should examine the documentation for
MOBILE4.1 inputs and determine if the M0BILE4.1 default
values were used for annual mileage accumulation rates,
registration by vehicle type, and registration by
vehicle age. If default values were not used for any
one of these parameters, answer the question "No" and
indicate in the Comments field which used site-specific
data.
2.8.5 In running M0BILE4.1, the inventory preparer should
have used the July ASTM volatility class value for
estimating ozone season gasoline Reid Vapor Pressure
(RVP). RVP is one of the key inputs to M0BILE4.1. If
something other than the July value was used, answer
the question "No" and indicate in the Comments field
what value was used. This information should be
contained in the documentation for the M0BILE4.1
inputs.
2.8.6 The reviewer should check the M0BILE4.1 inputs
documentation to determine if the M0BILE4.1 default
values were used for the vehicle operating mode
fractions or were site-specific values applied. The
default values are as follows:
- percent of VMT by non-catalyst vehicles in
the cold-start mode (PCCN) = 20.6%
- percent of VMT by catalyst-equipped vehicles
in the hot-start mode (PCHC) = 27.3%
- percent of VMT by catalyst-equipped vehicles
in the cold-start mode (PCCC) = 20.6%
If any one of the defaults was not used, answer the
question "No", and describe the site-specific operating
mode data used in the Comments field.
2.8.4 Were MOBI LEA.1 default values for annual
mileage accumulation rates, and
registration distribution by vehicle type
and age used?
2.8.5 Was the July ASTM volatility class used
for estimating ozone season gasoline RVP?

2.8.7 The reviewer should examine the M0BILE4.1 inputs
documentation to determine how VMT estimates were

urban transportation planning model did not include all
roads in the inventory area. If no documentation or
explanation is provided for these VMT estimates check
the "No" box.
2.9 CONSISTENCY CHECKS - AREA ON-ROAD MOBILE SOURCES
2.9.1 The reviewer should determine from the on-road mobile
source emissions documentation if the value used for
average summertime temperature was between 80 and 93°F.
If the temperature used was outside of this range,
answer the question "No" and enter the value used in
the Comments field.
2.9.2 In terms of the documentation for computing evaporative
VOC losses, the reviewer should determine if the
difference between the minimum and maximum temperatures
used was 24°F or less. If the difference was greater
than this value, answer the question "No" and indicate
in the Comments field what the range was and reasons
given for the range used.
2.9.3 The reviewer should check the MOBILE4.1 inputs for
speed to ensure that a value of between 2.5 and
55 miles per hour (the range of M0BILE4.1
acceptability) was used. If a value out of this range
was used, answer the question "No" and indicate in the
Comments field what speed was used, the road/vehicle
type combination it was used for, and the justification
for this speed.

2.9.4 The reviewer first needs to determine the VMT
apportionment by road type in each county on a
percentage basis. Once the apportionments are
calculated, the reviewer should compare the figures, by
each of the eight road types, to the values listed in
the checklist. If the calculated value is outside of
the stated range, answer the question "No" and indicate
in the Comments field what the calculated apportionment
was. If VMT data were not provided in the inventory or
if they were provided but not by road type, answer the
question "No" and indicate such in the Comments field.
2.9.5 The reviewer should calculate the ratio of VMT per
person per year for the inventory area. If more than
one county is represented in the inventory, the ratio
should be the sum of VMT in all the counties divided by
the sum of population in all of the counties. If this
ratio is outside of the range 1505 -18991, answer the
question "No" and enter the calculated range in the

2.9.6 The reviewer should calculate the annual ratio of VMT
to total gallons of gasoline sold in the inventory
area. If more than one county is represented in the
inventory, the ratio should be the sum of VMT in all
counties divided by the sum of gasoline sales in all of
the counties. If the ratio is outside of the range
15.9 - 20.7, answer the question "No" and enter the
calculated ratio in the Comments field.
VMT data should be present in the inventory
documentation. If VMT data are not given in the
inventory, answer the question "No" and state in the
Comments field that there were no VMT data.
Gasoline sales or throughput data should be available
in the inventory documentation in either the mobile
sources discussion or the vehicle refueling emissions
discussion. If gasoline sales data are not available
in the inventory, the reviewer has several options.
First, the data shown in Table 4-2 could be used. The
reviewer would need to prorate the state gasoline data
down to the county level using population. The
calculation would be:
(nonattainment area population/state population) x
state gasoline sales data
If this approach is not acceptable, the reviewer should
contact the individual state's transportation
department or other similar governmental agency to
obtain, county-specific fuel sales data.

2.10 COMPLETENESS CHECKS - AREA NON-ROAD MOBILE SOURCES
2.10,1 For a typical inventory area, the area non-road mobile
source inventory is expected to contain emission
sources in each of the listed categories. The reviewer
can quickly determine if these categories are included
by reviewing the overall inventory summary tables. To
assist the reviewer in locating this information,
Table 3-3 shows an example of a summary table generated
using PC-SAMs. If one or more of the categories are not
included, review the inventory documentation and
describe applicable explanations (and page numbers) in
the comment column. If emissions estimates were not
developed for all three of the pollutants check the

2.11 PROCEDURES CHECKS - AREA NON-ROAD MOBILE SOURCES
2.11.1 If agricultural activities occur within the inventory
area boundaries, emission estimates should be developed
for agricultural equipment. If the inventory submittal
states that no agricultural activities take place
within the inventory area then the reviewer should not
check either the "Yes" or "No" box but instead write
"N/A no agricultural activities" in the comment column
of questions 8.2.1 through 8.2.5 and reference the page
number in the report where that information is
documented. If the report simply does not discuss
emissions from agricultural equipment and does not
provide rationale for why emissions should not be
included then the reviewer should check the "No" box
and write "no estimate/no discussion" in the comment
column of questions 2.11.1 through 2.11.5.
If emission estimates are provided for agricultural
equipment, review the documentation supporting the
inventory submittal and determine if equipment
populations were determined from data in Census of
Agriculture. Denote in the comment column the report
page number where the information is documented. If
the documentation does not specify how equipment
population were derived check the "No" box.
2.11.2 Review the documentation supporting the inventory and
determine if an estimate of the number of cultivated
acres in each of the counties in the inventory area was

5.0 INVENTORY REVIEW SUMMARY AND FOLLOW-UP ACTIVITIES
At the conclusion of the initial quality review process, the
Region will need to communicate its findings back to the
inventory preparation agency and the State. Similarly, the
Region will also need to provide the Office of Air Quality
Planning and Standards (OAQPS) with feedback on the status of the
inventory review activities. At a minimum, this initial
communication should include a copy of the applicable completed
checklists found in Appendices A, B, and C of this document and a
transmittal memo that summarizes the deficiencies in the
inventory as identified by the Region.
The language in the transmittal memo should be specific and
directed at the areas needing improvement. The memo should not
just list items not contained in the inventory or just list
mistakes. The language should be positive and directed. For
example, the communication needs to say specifically what is
required and where in the inventory the material should be
placed. The comments should tell the State exactly what they
need to do to change their inventory, how the Region wants it
done, and why it should be done this way. The Region should
refer to the guidance materials listed in Table 1-1 to provide
backup support for their comments and requirements.
When the Region has finished its review process, there will
need to be a coordinator of all review comments who will examine
Appendices A, B, and C and determine the extent of the reviews
and proceed to gather and collect all comments. If more than one
person reviewed the same sections of the inventory, the
coordinator will have to assess all the comments and consolidate
them into a single set that represent the Region's position. If
different people were responsible for reviewing different parts
of the inventory (i.e., one for point sources, one for area,
etc.), then the coordinator may only have to pull together each
set of comments and put them in a common package. The Region
tls.023 _ _
-------
needs to make sure it provides the State with a clear and
consistent set of comments.
An example outline of a transmittal memorandum for sending a
Region's quality review comments is provided in Table 5-1. This
example only describes the general characteristics that would be
common to all memorandums. Each inventory and Regional review
process will have unique characteristics which will affect the
content and form of the memorandum. In general, the memo should
summarize the attached checklist, summarize inventory
deficiencies, request clarifications, summarize required actions
and changes necessary, and provide a suggested schedule for
revising the inventory. The memo should also provide a list of
Regional contact people for specific inventory parts that the
State can address questions to if it needs to reconcile a
comment.
Following the submittal of its comments, the Region should
monitor the progress of the preparing agency in revising the
inventory. Upon receipt of the revised inventory, the Region
will need to evaluate it to ensure that all previously identified
deficiencies have been corrected to the Region's satisfaction.
If the revised inventory satisfies the requirements, the Region
should send some type of correspondence to the State indicating
that the State has met the base year inventory requirements for
that nonattainment area. This correspondence should be copied to
OAQPS. If the revised inventory still does not conform to the
Region's requirements, additional documentation of deficiencies
will have to be made and sent to the preparing agency. This
process should continue until all requirements have been met.

Introduction
Define purpose of the memo
Identify the EPA groups involved in the review
- Identify the inventory addressed by the comments in terms
of the nonattainment area, the State, and the agencies
submitting and preparing the inventory
- Outline what is contained in the memo and describe any
attachments (e.g., the Appendix A checklists)
Summary of Review Checklist and Identification of Deficiencies
- For each applicable checklist in Appendices A, B, and C
identify missing or incomplete data and denote instances
of "No" answers to the checklist questions
For each item where a problem has been identified,
provide a narrative describing the deficiency, why the
item is deficient, and what generally is required to
correct the deficiency
Ideally, a summary table like that shown below would be
useful
- Make sure comments correspond organizationally to the
numbering system used in the inventory submittal

Required Actions/Corrections
- The Region should state precisely what revisions to the
draft inventory the State should make in order to gain
approval of the inventory
- The required revisions should be clearly tied to the
specific deficiencies outlined previously
- The Region should state clearly what it expects to see
in terms of content and format of the requested revisions
Use examples as necessary and refer to the published
guidance for support
In cases where additional documentation is needed,
provide specific guidance on what type of documentation
is acceptable. Do not make vague statements simply
requesting more documentation.
Schedule
- The Region should put forth to the State a tentative
schedule for making the revisions and responding with
a revised inventory.
Contacts
- The Region should identify specific contact people at
their offices that should be called to reconcile comments
on different parts of the inventory. It is likely that
the State may not understand all or parts of some
comments such that clarification by the Region will be
necessary.
