PREFACE *
This guideline describes the Air Quality Maintenance Areas
(AQMAs) which have been identified by the States, and designated M
by EPA, as areas having the potential to exceed National Ambient
Air Quality Standards (NAAQS) pursuant to the requirements of I
the FEDERAL REGISTER notice of June 18, 1973 (38 FR 15834).
The purpose of this guideline is to give the results of the Q
AQMA designation process, and provide information on land area •
and population for possible future use in studies such as air
quality modeling. •
The information in this guideline was obtained from several
sources: The U.S. Bureau of the Census, U.S. EPA Regional Offices, V
State Air Pollution Control Agencies, and the U.S. Department of
the Interior, Bureau of Indian Affairs.

INTRODUCTION
1. DESCRIPTION OF AIR QUALITY MAINTENANCE AREAS (AQMAs)
A. General
The AQMAs described in this guideline contain approximately 58%
of the total population of the United States and 11% of its land area.
They were identified pursuant to the requirements of 40 CFR 51.12(e),
which was published in the FEDERAL REGISTER of June 18, 1973 (38 FR
15834). This regulation specified that all State implementation plans
(SIPs) must identify those areas (counties, urbanized areas, standard
metropolitan statistical areas, etc.) which, due to current air
quality and/or projected growth rate may have the potential for
exceeding any NAAQS within the subsequent 10-year period.
All AQMAs, including interstate AQMAs, are catalogued here in
alphabetical order under the states in which they are located. The
states are also arranged in alphabetical order. Maps showing AQMA
locations are included for each state, and one for the country
as a whole.
B-. Descriptive Data
For each AQMA, the following information is given: AQMA name,
number, land area in both square kilometers and square miles,* 1970
*
Several assumptions were made concerning land area. Land areas
were supplied by U.S. Census Bureau materials in square miles.
Area in square kilometers was calculated using a conversion factor
of 2.59 km2/mi2, then rounding off the figures to the nearest
whole number. The U.S. Bureau of Census definition of land area
reads: "Dry land and land temporarily or partially covered by
water, such as marshland, swamps, and river flood plains; streams,
sloughs, estuaries, and canals less than 1/8 of a statute mile in -i
width; and lakes, reservoirs, and ponds less than 40 acres of area".
-------
Census population, geographical composition of the AQMA, and
pollutants for which it is designated. Interstate AQMAs are listed
under each of the co-member states, with land area, population,
geographical information, and pollutants shown for the entire AQMA.
The AQMA number is listed only for that state's portion of the AQMA.
In two AQMAs, the New Jersey portion of the Metropolitan Philadelphia
Interstate AQMA and the Kentucky portion of the Cincinnati Interstate
AQMA, certain counties are designated for specific pollutants, with
other counties in the same AQMA designated for different pollutants.
These differences are indicated by footnotes.
C. Maps
The descriptive data for each state are followed by a map of that
state showing the geographical outlines of each AQMA together with its
name, number and pollutants for which it was identified. For inter-
state AQMAs, the out-of-state portions are included on the maps with
dotted lines indicating State boundaries. A United States map outlines
l
AQMAs for the entire country and also shows the EPA regional boundaries.
For Oregon and Washington, where areas already under study by local
agencies were desginated as AQMAs, maps of some individual AQMAs are
included. For California, maps are provided for the Sacramento Valley t
Area and Southeast Desert AQMAs in addition to the word descriptions
X
for these areas.
-------
D. Tables
Table 1 lists the name and number of each AQMA in alphabetical
order by states and the pollutants for which they are designated.
The percentages of population and land area included in AQMAs for
each State are shown in Table 2. Table 3 presents the ratio of
people to land area for each AQMA.
2. PROCEDURES USED TO IDENTIFY AQMAs
Volume 1 (EPA-450/4-74-001) in this guideline series gave the
procedure for identifying AQMAs. Briefly, this was done by applying
initial designation criteria to exclude obvious nonproblem areas, or
include obvious problem areas. For those areas neither included or
excluded, an analysis was made as follows:
(a) Emissions in 1985 were estimated by adjusting known emission
inventories to account for growth and reductions expected from
SIP control strategies,
(b) Air quality in 1985 was predicted by applying various air
quality models to estimated emissions, and,
(c) Air quality in 1985 was compared with NAAQS to determine
if the area should be identified as an AQMA.
As specified in Volume I, all Standard Metropolitan Statistical Areas
(SMSAs) were investigated. In addition, national resource and industrial
development areas in several western states and Puerto Rico were also
-------
examined. Natural resource development areas are non-SMSAs which have
the potential to exceed any NAAQS due to existing or planned development
of natural resources. Examples are areas containing coal, lignite or
oil shale deposits where mining operations as well as processing plants
will be located. Industrial development areas are non-SMSA areas
which have the potential to exceed NAAQS due to concentrated indus-
trial activity. These areas are frequently located near natural
resource development areas. Since traditional growth indicators were
not applicable in natural resource or industrial development areas
they were identified on a case-by-case basis using the best projection
data available. These areas are identified by footnotes in Table 1.
AQMAs may be de-designated in cases where the State's subsequent
detailed analysis indicates national standards will be maintained and
no AQMA, plan is required.
3. AQMA NUMBERING
Each AQMA is identified by a four-digit number. The first three
digits of this number indicate in which AQCR the AQMA is located.
Letters of the alphabet were sequentially assigned to the fourth space
in order to uniquely identify each AQMA within the AQCR. For example,
AQCR #031 in California contains four AQMAs: these are assigned AQMA
numbers 031A, 031E, 031C, and 031D.
In a few cases, AQMAs cross AQCR boundaries. Here, the AQCR
which contains the major portion of the AQMA, supplied the first
three digits of the AQMA number. The Colorado-Utah Oil Shale
-------
Interstate AQMA is the only exception; it is cop-prised of roughly
equal portions of three AQCRs. The lowest AQCR number was arbi-
trarily chosen for that AQMA.
Interstate AQMAs are so designated by placing a dash and an "I"
after the four digit number. Each State's portion of an Interstate
AQMA was assigned a separate number by lettering sequentially the fourth
space in the AQMA numbers. This is done according to alphabetical
arrangement of the states involved. For instance, the Illinois portion
of the St. Louis Interstate AQMA is numbered 070A-I, while the Missouri
portion of the St. Louis Interstate is AQMA number 070B-I.
4. SOURCES OF INFORMATION

B. United States Bureau of the Census
Population and land area data for AQMAs composed of entire
counties were obtained from Table 9 of the U.S. Bureau of the
p
Census publication, Part A, Number of Inhabitants .
For AQMAs which include portions of counties (i.e., areas
smaller than counties, or not coincident with county borders),
population and land area data were obtained from several sources,
-------
These include three other tables in the U.S. Bureau of Census
publication, Part A, Number of Inhabitants'.
Maps suitable for the drawing in of AQMAs were furnished by the
Geography Division of the U.S. Bureau of the Census, Social and Economic
Statistics Administration, U.S. Department of Commerce, Washington, D.C.
20233.
C. Other Sources
1. Land area and population estimates for portions of
counties in California, Nevada, Oklahoma, Oregon, and Washington
were provided by the State agencies. South Carolina furnished
population estimates for its AQMAs, and the land areas were
estimated by planimeter measurement.
2. Land area data for the portions of counties included in
AQMAs in Connecticut, Massachusetts, New York, and Pennsylvania
were obtained from Area Measurement Reports, 1960 Census, published
by the U.S. Bureau of the Census.4 This 1960 data was then
verified by Regional Offices I, II, and III in order to account
for any changes in land area which took place between 1960 and
1970.5
3. Land area and population data for that portion of the
Northern Cheyenne Indian Reservation located in Big Horn County
of Montana were provided through the Region VIII office by the
U.S. Department of the Interior, Bureau of Indian Affairs.
4. Maps useful in the drawing in of AQMAs, especially those AQMAs
comprised of portions of counties, were obtained for California, Colorado,
Connecticut, Illinois, Massachusetts, Montana, Nevada, New York, Oklahoma,
Oregon, Pennsylvania, Rhode Island, South Carolina, Virginia, and Wash-
ington, through the respective Regional Offices from State agencies.

This document describes each of the Air Quality Maintenance Areas (AQMAs)
identified in the Federal Register Notices of April 29, 1975 (FR 18726), June
2, 1975 (FR 23746) and September 9~, 1975 (FR 41942). For each AQMA in each
State, the following information is given: land area, population, geographical
composition and pollutants for which the area was identified. A map of each
State shows the location of intra-state and interstate AQMAs. These are also
shown on a U.S. map. Some data are presented in tabular form: AQMA name and
pollutants by State, AQMA name and number by State, percentage of State popula-
tion and percentage of State land area in AQMAs by State, and AQf'A population
densities by State.
