notify the appropriate EPA Regional Office.
(1) States are required to report emissions data in an electronic
format to one of the locations listed in this paragraph (h). Several
options are available for data reporting.
(2) An agency may choose to continue reporting to the EPA Aerometric
Information Retrieval System (AIRS) system using the AIRS facility
subsystem (AFS) format for point sources. (This option will continue for
point sources for some period of time after AIRS is reengineered (before
2002), at which time this choice may be discontinued or modified.)
(3) An agency may convert its emissions data into the Emission
Inventory Improvement Program/Electronic Data Interchange (EIIP/EDI)
format. This file can then be made available to any requestor, either
using E-mail, floppy disk, or value added network (VAN), or can be
placed on a file transfer protocol (FTP) site.
(4) An agency may submit its emissions data in a proprietary format
based on the EIIP data model.
(5) For options in paragraphs (h)(3) and (4) of this section, the
terms submitting and reporting data are defined as either providing the
data in the EIIP/EDI format or the EIIP based data model proprietary
format to EPA, Office of Air Quality Planning and Standards, Emission
Factors and Inventory Group, directly or notifying this group that the
data are available in the specified format and at a specific electronic
location (e.g., FTP site).
(6) For annual reporting (not for triennial reports), a State may
have sources submit the data directly to EPA to the extent the sources
are subject to a trading program that qualifies for approval under
Sec. 51.121(q) of this part, and the State has agreed to accept data in
this format. The EPA will make both the raw data submitted in this
format and summary data available to any State that chooses this option.

terms shall have the meanings set forth below:
(1) Annual emissions. Actual emissions for a plant, point, or
process, either measured or calculated.
(2) Ash content. Inert residual portion of a fuel.
(3) Area designation. The designation of the area in which the

on the reported maximum continuous steam flow. Capacity is calculated in
units of MMBtu/hr.
(5) Control device type. The name of the type of control device
(e.g., wet scrubber, flaring, or process change).
(6) Control efficiency. The emissions reduction efficiency of a
primary control device, which shows the amount of reductions of a

operates.
(8) Emission factor. Ratio relating emissions of a specific
pollutant to an activity or material throughput level.
(9) Exit gas flow rate. Numeric value of stack gas flow rate.

temperature.
(11) Exit gas velocity. Numeric value of an exit gas stream
velocity.
(12) Fall throughput (%). Portion of throughput for the 3 fall
months (September, October, November). This represents the expression of
annual activity information on the basis of four seasons, typically
spring, summer, fall, and winter. It can be represented either as a
percentage of the annual activity (e.g., production in summer is 40
percent of the year's production), or in terms of the units of the
activity (e.g., out of 600 units produced, spring = 150 units, summer =
250 units, fall = 150 units, and winter = 50 units).
(13) Federal ID code (plant). Unique codes for a plant or facility,
containing one or more pollutant-emitting sources.
(14) Federal ID code (point). Unique codes for the point of
generation of emissions, typically a physical piece of equipment.

where emissions from one or more processes are released into the
atmosphere.
(16) Federal Information Placement System (FIPS). The system of
unique numeric codes developed by the government to identify States,
counties, towns, and townships for the entire United States, Puerto
Rico, and Guam.
(17) Heat content. The thermal heat energy content of a solid,
liquid, or gaseous fuel. Fuel heat content is typically expressed in
units of Btu/lb of fuel, Btu/gal of fuel, joules/kg of fuel, etc.

operates.
(19) Maximum design rate. Maximum fuel use rate based on the
equipment's or process' physical size or operational capabilities.
(20) Maximum nameplate capacity. A measure of the size of a
generator which is put on the unit's nameplate by the manufacturer. The
data element is reported in megawatts (MW) or kilowatts (KW).
(21) Mobile source. A motor vehicle, nonroad engine or nonroad
vehicle, where:
(i) Motor vehicle means any self-propelled vehicle designed for
transporting persons or property on a street or highway;
(ii) Nonroad engine means an internal combustion engine (including
the fuel system) that is not used in a motor vehicle or a vehicle used
solely for competition, or that is not subject to standards promulgated
under section 111 or section 202 of the CAA;
(iii) Nonroad vehicle means a vehicle that is powered by a nonroad
engine and that is not a motor vehicle or a vehicle used solely for
competition.
(22) Ozone season. The period May 1 through September 30 of a year.
(23) Physical address. Street address of facility.
(24) Point source. A non-mobile source which emits 100 tons of
NOX or more per year unless the State designates as a point
source a non-mobile source emitting at a specified level lower than 100
tons of NOX per year. A non-mobile source which emits less
NOX per year than the point source threshold is an area
source.
[[Page 163]]
(25) Pollutant code. A unique code for each reported pollutant that
has been assigned in the EIIP Data Model. Character names are used for
criteria pollutants, while Chemical Abstracts Service (CAS) numbers are
used for all other pollutants. Some States may be using storage and
retrieval of aerometric data (SAROAD) codes for pollutants, but these
should be able to be mapped to the EIIP Data Model pollutant codes.
(26) Process rate/throughput. A measurable factor or parameter that
is directly or indirectly related to the emissions of an air pollution
source. Depending on the type of source category, activity information
may refer to the amount of fuel combusted, the amount of a raw material
processed, the amount of a product that is manufactured, the amount of a
material that is handled or processed, population, employment, number of
units, or miles traveled. Activity information is typically the value
that is multiplied against an emission factor to generate an emissions
estimate.
(27) SCC. Source category code. A process-level code that describes
the equipment or operation emitting pollutants.
(28) Secondary control efficiency (%). The emissions reductions
efficiency of a secondary control device, which shows the amount of
reductions of a particular pollutant from a process' emissions due to
controls or material change. Control efficiency is usually expressed as
a percentage or in tenths.

of Commerce's categorization of businesses by their products or
services.

applicable and used for calculations of emissions estimates.
(36) Summer throughput (%). Portion of throughput or activity for
the 3 summer months (June, July, August). See the definition of Fall
Throughput.
(37) Summer work weekday emissions. Average day's emissions for a
typical day.
(38) VMT by Roadway Class. This is an expression of vehicle activity
that is used with emission factors. The emission factors are usually
expressed in terms of grams per mile of travel. Since VMT does not
directly correlate to emissions that occur while the vehicle is not
moving, these non-moving emissions are incorporated into EPA's MOBILE
model emission factors.
(39) Week/year in operation. Weeks per year that the emitting
process operates.
(40) Work Weekday. Any day of the week except Saturday or Sunday.
(41) X coordinate (latitude). East-west geographic coordinate of an
object.
(42) Y coordinate (longitude). North-south geographic coordinate of
an object.
