                                     SCOPE

     This report summarizes State Implementation Plan regulations on the
emission of sulfur oxides from fuel  combustion equipment.  The definition of
fuel combustion equipment varies slightly from state to state but, in all
states, these regulations apply to steam-electric generating plants (power
plants) and industrial boilers which burn fuel to generate power.  In many
cases, the regulations apply to all  fuel users.  The regulations generally do
not apply to S02 emissions from incineration or industrial processes such as
steel production or coking.

     State Implementation Plans (SIP) are designed to prevent local ambient
air concentrations from exceeding the National Ambient Air Quality Standards.
In addition to SIP regulations, which are Federally approved and legally
enforceable, some states, counties,  or cities have adopted local S02 regu-
lations which may be more stringent than SIP emission requirements.  While
fuel burning sources may be required to comply with these regulations, in most
cases, local regulations are not included in this summary.  Where local regu-
lations do appear, they are clearly identified as such.

                               INTRODUCTION

     This report contains a summary of each state's implementation plan reau-
lations  for sulfur oxides; a background section explaining the relationship
between  these regulations, the Federal ambient air standards,  and Federal new
source regulations;  a  comparative  analysis of the various State regulations,
and three appendices.   Appendix A  presents the National Ambient Air Quality
Standards, Appendix  B  summarizes the Federal new source regulations for S02,
and Appendix C explains how to convert units of measure of sulfur oxide regu-
lations  to a common  basis.

     Regulations aimed at controlling ambient air concentrations of sulfur
dioxide  (S02) may be written to limit either the sulfur content of fuel or
the emission of sulfur dioxide or  sulfur oxides. To he consistent with
commonly used terminology, the following discussions refer to  all sulfur
limiting regulations as S02 regulations.

     This document is  not an official FPA listing of SIP emission regulations
for S02, but reflects  an interpretation of these regulations which was prepared
by EPA's Strategies  and Air Standards Division for strategy analysis.  Since
the primary responsibility for interpreting and enforcing these regulations
lies with each state or local air  pollution control office, these data should
not be used to make  assumptions regarding the legal compliance status of
any particular facility.

-------
     The summary initially was compiled from State regulations published in
the Environment Reporter and the Code of Federal Regulations.  To verify details
of how these regulations are being enforced, a team of engineers visited the
Office of Enforcement or the Office of Air Programs at each FPA regional office.
In some instances, the state air pollution control offices were contacted.
Following these visits, the regulations have been undated by tracking revisions
to State Implementation Plans which have been published in the Federal Register.
This summary incorporates revisions that have been approved through February 7,
1976 and, in a few cases, identifies revisions which are in nrogress.

     This summary provides a data base of S02 regulations for use by EPA and
other organizations in analyzing the issues of S02 control and National fuels
policies.  Since these data were not collected directly from the individual
state air pollution control agencies, there exists a possibility of errors in
some of these summaries.  To assist in correcting these errors and maintaining
an accurate data base, the Strategies and Air Standards Division invites comments
on this summary, especially from state air pollution control agencies and from
EPA regional offices.  Comments will be incorporated into revisions of this
document which will be published periodically.  The revisions will reflect
changes to State Implementation Plans which have been approved by EPA since the
publication of this document and will correct inaccuracies which may appear in
this report.  Please address comments to:

                 BACKGROUND:  RELATIONSHIP np NATIONAL AMBIENT
        AIR QUALITY STANDARDS, STATE EMISSION REGULATIONS, AND FEDERAL
                             NEW SOURCE STANDARDS

     The Clean Air Act of 1970 qave the Environmental Protection Agency (EPA)
the responsibility and authority to control air pollution in the United States
and its territories.  Among other responsibilities, the Clean Air Act reouired
the Administrator of EPA to promulgate National Ambient Air Ouality Standards*
for pollutants which he determines adversely affect public health and welfare.
In 1971, EPA promulgated National Ambient Air Ouality Standards (NAAOS) for
six pollutants--sulfur dioxide, nitrogen dioxide, narticulate matter, carbon
monoxide, hydrocarbons, and photochemical oxidants (Appendix A).  For each
pollutant, two standards were issued.  Primary standards were set at levels
necessary to protect the public health and were to be met no later than three
years from the date of promulgation (subject to limited extensions of up
to three years).  Secondary standards were designed to protect the public
from adverse effects to their welfare, such as crop damage, reduction in
atmospheric visibility, and corrosion of materials and were to be met in
a time frame considered reasonable by the Administrator.

     To implement these standards, the Act required each state to adopt and
submit to EPA a plan for attaining, maintaining, and enforcing the National
Ambient Air Ouality Standards in all regions of the state.  Each state, there-
fore, decided, (for each pollutant) the total emission reduction needed to
maintain local ambient air levels below the standards and decided which emission
sources to control and to what extent.  The State Implementation Plans (SIPs)
prescribed emission limiting regulations, timetables for compliance with the
limitation, and any other measures, such as land-use and transportation controls,
which were necessary to insure attainment and maintenance of the standards.
The plans were reviewed by EPA and approved if they demonstrate^ that at a
minimum the primary standards would be attained within three years (subject to
* National Ambient Air Ouality Standards (usually expressed in micrograms per
  cubic meter) establish a maximum level of pollution nermitted in the ambient
  air.

-------
the compliance date extension provisions of the Act) and that secondary standards
would be attained within a reasonable period of time.  Disapproved plans (or
parts thereof) were returned to the States for revision, or in some cases,
substitute regulations were promulgated by EPA.

     While the primary responsibility for enforcing SIP regulations rests with
the individual States, the Administrator of EPA is responsible for assuring that
all implementation plan requirements are fulfilled.  As a result, EPA provides
technical and legal assistance to the States in enforcing SIP regulations.  If
any state fails to enforce its implementation plan regulations, the Federal
Government may commence a number of administrative or legal actions directed
toward non-complying sources.

     Most of the State implementation plans were approved in 1972.  Following
initial approval of the SIPs, many states began submitting to EPA revisions
to their implementation plan, many of which alter the emission limitations.
Usually, these revisions are based on additional .air quality measurement data
or on a more detailed technical anlaysis of air pollution control strategies.
When approved by EPA, these revisions become a part of the implementation plan.

     In addition to the SIP limitations, emissions from certain sources are
restricted further by Federal Standards of Performance for New Stationary Sources
(commonly referred to as new source performance standards).  A new emission
source is one which is designed and constructed after the formal proposal of new
source regulations.  New sources include newly constructed facilities, new
equipment which is added to existing facilities, and existing equipment which
is modified in such a way that results in an increase of pollutant emissions.
New source standards limit specific pollutant emissions from categories of
sources (such as fossil fuel-fired steam generators, municipal incinerators)
which the Administrator determines may contribute significantly to the endanger-
ment of public health and welfare.  For these sources, the Act requires the
Administrator to promulgate emission limitations which will require installation
of the best systems of emission reduction which he determines have been adequately
demonstrated.  Cost factors are considered in making this determination.   Federal

-------
new source standards help prevent the occurrence of new air pollution problems,
encourage improvements in emission control technology, and provide a mechanism
for controlling pollutants which EPA suspects are hazardous, but for which
insufficient information is available to regulate such pollutants under other
provisions of the Act.

     Over the past few years, much attention has been focused on emission regu-
lations for sulfur oxides since these regulations impact the supply of fuel,
particularly coal, which can be burned to produce electrical energy.  While
United States supplies of coal are plentiful, some of this coal is too high in
sulfur content to be burned in compliance with State and Federal regulations for
S02 without the use of emission reduction systems, which, in some cases, are
either costly or impractical.  As a result, many states have been reevaluating
their sulfur oxide regulations to insure that scarce low sulfur fuels are
being required only in areas where they are needed to protect public health.
In some cases, States have revised their sulfur regulations to allow the burning
of higher sulfur fuels in less polluted areas where they can be burned without
violating ambient air quality standards.

-------
                    COMPARATIVE ANALYSIS OF S02 REGULATIONS

     This summary of SIP emission requirements clearly shows the complexity and
diversity of S02 emission regulations for fuel combustion.   These regulations
vary as to the units of measure in which the sulfur limiting provision is
expressed and the equipment (boiler, stack, or entire plant) to which the regu-
lations apply.  In addition, some states control all emission sources equally,
while other states prescribe different emission limits for sources according
to the fuel used, the geographic location, the size of the source, or the type
of source  (e.g. power plant or other combustion units).  The following dis-
cussion highlights the diversity of the regulations and explains some of the
more peculiar and complex regulations.

     Sulfur dioxide emissions most commonly are regulated either by limiting
the amount of sulfur or sulfur dioxide emitted per unit heat input (#S/MMBtu,
#S02/MMBtu) or by limiting the sulfur content by weight (#S) that a fuel can
contain.   Sulfur dioxide regulations also are written in parts of S02 per million
parts by volume of stack gas (ppm S02) or limit the amount of S02 emitted per hour
(#S02/hr).  Six states, or parts thereof specify ambient air quality regulations
only (i.e. no specific emission limit for a source).  Other methods of limiting
S02 emissions which appear in the SIPs include requiring a percent control of
input sulfur  (% control) and requiring application of "latest reasonably available
control technology" (Florida) or "new proven technologies" (Texas).

     Some of the above mentioned methods for regulating S02 control the emissions
of sulfur oxides more directly than do others, and each method has different
implications regarding fuels that legally can be burned.  For instance, a 2S
regulation is a fuel restriction and, therefore, does not directly limit sulfur
oxide emissions from a stack.  To illustrate, a regulation requiring a coal-fired
boiler to  reduce its fuel sulfur from 3% to 1% may appear to result in a 672
reduction of S02 emissions.  This assumption is valid only if the lower sulfur
fuel used to comply with the regulation has the same heat content  (Btu/lb) as
the original fuel.  If, however, the lower sulfur fuel has a lower heat content
than the original fuel, then the rate of fuel consumption for the boiler will
have to be increased to maintain the heat output at existing levels.  As a result,

-------
the emission reduction achieved by complying with this hypothetical regulation
may be less than 67%.  The degree less than'672 would depend upon the heating
value of the complying coal.  On the other hand, a regulation requiring a
boiler to reduce emissions from ".5 *S02/MMBtu to 1.5 *S02/MMBtu,  in all cases,
will result in a 67% reduction of S02 emissions because this emission rate takes
into account the total heat generated by the boiler.

     Regulations written in £S02/hour directly control the amount  of sulfur
emissions,  but the sulfur content of fuel that can be used to comply with a
S02/hr regulation is a function of other parameters in addition to the value
of the regulation.   For instance, consider a boiler operating at full capacity
 (i.e. maximum designed fuel consumption rate) and then at one-half of full
capacity.   In both cases, assume that the boiler is meeting the ^S02/hr emission
requirement.  When operating at one-half of full capacity, the boiler legally
can burn  a  fuel with twice the sulfur content that it can burn when operating
at full capacity, because the rate of fuel consumption (and, thus, sulfur
 input to  the boiler) has been reduced by one-half.  Likewise, the  fuel sulfur
required  to meet a regulation expressed in ppm S02 will vary depending on the
amount of excess air  (air injected during the combustion process)  specified
for computing the emission  limit.  For example, to comply with a regulation
of 500 ppm  S02 at 50% excess air would require a fuel with about 0.86 %S.  But
to comply with the same emission limit at 12% excess air would require a fuel
with  a sulfur content of about 0.65 %S.

      On the other hand, the effect of ambient air quality regulations  (on
emissions), which have been approved in Arkansas, Missouri, Oklahoma, Texas,
Wisconsin,  and Wyoming is difficult to predict.  These regulations were
approved  by EPA because no violations of the National Ambient Air  Quality
Standards had .been measured in these areas and because the States  anticipated
no industrial growth which might result in contravention of the air standards.
If, however, the state ambient air quality standard is violated in these areas,
the regulations provide no direct legal mechanism for requiring a  source to
reduce S02  emission.  To control a source once an air standard is  violated,  the
state might exercise one of several enforcement actions, including fining the

-------
source, issuing an enforcement order, or adopting a continuous emission limi-
tation.  If, however, a National Ambient Air Quality Standard (NAAQS)  is
violated, EPA would require the state to adopt and submit a State Implementation
Plan revision, setting forth emission limitations aimed at preventing  future
NAAQS violations.  Similarly, it is difficult to predict the impact of regu-
lations in Texas and Florida which call for the use of reasonably available
control technologies on certain sources.

     To assist in comparing S02 regulations on a plant-by-plant basis,
Appendix C contains equations for converting S02 emission regulations  into
common units of measure of ?S and £S02/MMBtu based on the heat content of
the fuel burned and the excess air specified in the applicable regulation.

     Besides the various units of measure employed, regulations also vary as
to the equipment upon which the emission limit is enforced.  Twenty-five
states or territories enforce their regulations on a boiler basis, thirteen
on a stack basis, and eighteen on a total plant basis (all boilers collec-
tively).  In considering compliance with a regulation, this information
determines whether a source is allowed to average its emission over all
boilers  (or stacks) or if each boiler  (or stack) must comply with the
regulation.

     About one-third of the states regulate specific fuel types.  These regu-
lations  usually control oil-fired sources more strictly than coal-fired
sources  since, in general, oil contains  less sulfur and has a higher heat
content  than does coal.  But, in some  cases, such as Mew Jersey, the sulfur
restriction for coal is more stringent than the restriction for oil; the
objective of this regulation being to  prohibit the use of coal without flue
gas cleaning equipment.  The range of  fuel types which are  individually
specified in the various regulations include oil, *1 to -6  oil  individually,
all distillate oils, all residual oils,  coal, anthracite  coal,  bituminous
coal,  lignite, all solid fuels, all  liquid fuels, gaseous fuels, fossil fuels,
and non-commerical fuels.  Consideration of these provisions  is  important  in
determining if a particular regulation applies to uncommon  fuels such  as
petrochemical by-products or solid waste.

-------
     About half of the states have specific S02 regulations for various geo-
graphic areas within the state.  These geogranhic areas might be specified
as cities, counties, Federal air quality control regions (AOCP), Standard
Metropolitan Statistical Areas (SMSA), or some locally defined geographic
region.   In some areas, including Arizona, New Mexico and Puerto P.ico,
regulations have been promulgated which apply to specific plants.

     In about one-third of the states, the size of the source determines
whether or not the source must comply with an S02 emission limitation and
if so, the stringency of the limitation.  In most cases, source size is
defined by the heat input rate measured in millions of Btu per hour
 (MMBtu/hr).  Other methods of defining source size include pounds of steam
generated per hour  (#steam/hr) and emission potential in tons of S02 emitted
per year  (tons S02/yr).  In some states, the magnitude of the emission limit
is determined by the heat input range under which a source falls.  In these
states, larger sources  usually are controlled more stringently than smaller
sources.  For instance, in parts of Nevada, boilers with heat input rate of
less than 250 MMBtu/hr must comply with an emission limit of 0.7 #S/MMBtu
while  boilers greater than 250 MMBtu/hr must comply with an emission limit
of 0.1 #S/MMBtu  (250 MMBtu/hr translates to a boiler with an associated
generating capacity of  about 25 megawatts).  In Pennsylvania, West Virginia,
Virginia, and Indiana the heat input rate is inserted into an equation which
computes  the allowable  emission limit.

     Over half of the states employ more than one of the parameters discussed
above  in  their regulations.  In addition, about 35/^ of the states have
separate  regulations for new sources and about 10% have regulations for
existing  sources that become more stringent over time.  For example, in
North  Carolina all existing sources currently must comply with an emission
limit  of  2.3 #S02/MMBtu; after July 1, 1980, these sources can emit no more
than 1.6  #S02/MMBtu.

     In a few states  (for instance, New Hampshire and parts of New York), the
limits on emissions or  fuel quality are specified as maximum values averaged
over a given time period.  M0st regulations, however, state that emissions or

-------
sulfur content shall  not exceed a maximum value.   This phraseology implies
that instantaneous compliance with the limit is required.

                       SULFUR OXIDE EMISSION REGULATIONS

     In the following summary of State Implementation Plan regulations for
S02, one page has been devoted to each state regulation (two pages for Ohio
where the summary was lengthy).  The states and U. S. territories appear
alphabetically with the state name on the top of each page.  Under the name
is a checklist for identifying the units of measure in which the emission
limit is expressed and the equipment on which the regulation is enforced.
Also presented is the time period over which emission measurements are
averaged for determining compliance with the regulation.  Below this infor-
mation, the emission regulation is summarized.  Where possible, the summaries
were formatted similarly, but in each case a format was selected which was
believed to be best suited for a lucid explanation of the regulation.  Where
needed for clarity, further explanatory information about the regulation is
presented at the end of each summary in a paragraph entitled "NOTES."

     In the past, other reports have presented SIP regulations in a tabular
format, enabling easy comparison.  In many cases, however, presenting regu-
lations in this manner sacrifices some accuracy and detail.  In contrast,
this summary has been written in a freely-formatted style, thus portraying
the regulations in greater detail than in other published summaries.  As a
result, this summary is lengthy, but is easily understood and will be easy to
update.

     This summary sometimes references regulations that have been "adopted"
or  "proposed."  Proposed regulations refer to regulations adopted by a
state or written by EPA which have been proposed formally in the Federal
Register.  Adopted regulations refer to the regulations that have been
adopted by a State legislative body, but which either have not been
submitted to EPA for approval or have been submitted to EPA but have not
been proposed formally in the Federal Register.

COMMENTS
The secondary annual standard (60yg/m3)
is a guide for assessing SIPs to
achieve the 24-hour secondary standard.


The continuous Saltzman, Sodium
Arsenite (Christie), TGS, and Cheir.ilum-
inescence have been proposed as replace-
ments for the J-H method. New FRM
to be decided upon by Jan. 1975.
The FRM measures 03 (ozone)
The HC standard is a guide to devising
SIPs to achieve the Oxidant standard.
The HC standard does not have to be
met if the oxidant standard is met.
Not to be exceeded more' than once per year.
NOTE:  The air quality standards and a description  of  the  reference methods were published on April  30, 1971  in 42 CFR 410, recodified
       to 40 CFR 50 on November 25, 1972.
