                         1.0  EXECUTIVE SUMMARY

     The enclosed report is the U.S.  Environmental  Protection Agency's (EPA)
response to Section IV of the Energy  Supply and Environmental Coordination
Act of 1974 (ESECA).  Section IV requires EPA to review each State Implemen-
tation Plan (SIP) to determine if revisions can be  made to control regula-
tions for stationary fuel combustion  sources without interfering with the
attainment and maintenance of the National  Ambient  Air Quality Standards
(NAAQS).  In addition to requiring that EPA report  to the State on whether
control regulations might be revised, ESECA provides that EPA must approve
or disapprove any revised regulations relating to fuel burning stationary
sources within three months after they are submitted to EPA by the States.
The States may, as in the Clean Air Act of 1970, initiate State Implementa-
tion Plan revisions; ESECA does not,  however, require States to change any
existing plan.

     Congress has intended that this  report provide the State with informa-
tion on excessively restrictive control regulations.  The intent of ESECA
is that SIP's, wherever possible, be  revised in the interest of conserving
low sulfur fuels or converting sources which burn oil or natural gas to coal.
EPA's objective in carrying out the SIP reviews, therefore, has been to try
to establish if emissions from combustion sources may be increased.  Where
an indication can be found that emissions from certain fuel burning sources
can be increased and still attain and maintain NAAQS, it may be plausible
that fuel resource allocations can be altered for "clean fuel savings" in
a manner consistent with both environmental and national energy needs.

     In many respects, the ESECA SIP  reviews parallel EPA's policy on clean
fuels.  The Clean Fuels Policy has consisted of reviewing implementation
plans with regards to saving low sulfur fuels and,  where the primary sulfur
dioxide air quality standards were not exceeded, to encourage States to
either defer compliance regulations or to revise the S0£ emission regulations.
The States have also been asked to discourage large scale shifts from coal
to oil where this could be done without jeopardizing the attainment and
maintenance of the NAAQS.

-------
     To date, EPA's fuels policy has addressed only those States with the
largest clean fuels saving potential.  Several of these States have or are
currently in the process of revising S02 regulations.  These States are
generally in the Eastern half of the United States.  ESECA, however, extends
the analysis of potentially over-restrictive regulations to all 55 States
and territories.  In addition, the current reviews address the attainment
and maintenance of a!I  the National Ambient Air Quality Standards.

     There are, in general, three predominant reasons for the existence of
overly restrictive emission limitations within the State Implementation
Plans.  These are (1) the use of the example region approach in developing
State-wide air quality control strategies; (2) the existence of State Air
Quality Standards which are more stringent than NAAQS; and (3) the "hot
spots" in only part of an Air Quality Control  Region (AQCR) which have been
used as the basis for controlling the entire region.  Since each of these
situations affect many State plans and in some instances conflict with
current national energy concerns, a review of the State Implementation Plans
is a logical follow-up to EPA's initial appraisal of the SIP's conducted in
1972.  At that time SIP's were approved by EPA if they demonstrated the
attainment of NAAQS p_r more stringent state air quality standards.  Also,
at that time an acceptable method for formulating control  strategies was
the use of an example region for demonstrating the attainment of the standards

     The example region concept permitted a State to identify the most pol-
luted air quality control region (AQCR) and adopt control  regulations which
would be adequate to attain the NAAQS in that region.  In  using an example
region, it was assumed that NAAQS would be attained in the other AQCR's of
the State if the control regulations were applied to similar sources.   The
problem with the use of an example region is that it can result in excessive
controls, especially in the utilization of clean fuels, for areas of the
State where sources would not otherwise contribute to NAAQS violations.  For
instance, a control  strategy based on a particular region  or source can re-
sult in a regulation requiring 1 percent sulfur oil to be  burned state-wide
where the use of 3 percent sulfur coal  would be adequate to attain NAAQS in
some locations.

-------
     EPA anticipates that a number of States will use the review findings
to assist them in making the decision whether or not to revise portions of
their State Implementation Plans.  However, it is most important for those
States which desire to submit a revised plan to recognize the review's limi-
tations.  The findings of this report are by no means conclusive and are
neither intended nor adequate to be the sole basis for SIP revisions; they
do, however, represent EPA's best judgment and effort in complying with
the ESECA requirements.  The time and resources which EPA has had to pre-
pare the reports has not permitted the consideration of growth, economics,
and control strategy tradeoffs.  Also, there have been only limited disper-
sion modeling data available by which to address individual point source
emissions.  Where the modeling data for specific sources were found, how-
ever, they were used in the analysis.

     The data upon which the reports' findings are based are the most cur-
rently available to the Federal Government.  However, EPA believes that
the States possess the best information for developing revised plans. The
States have the most up-to-date air quality and emissions data, a better
feel for growth, and the fullest understanding for the complex problems
facing them in the attainment and maintenance of air quality.  Therefore,
those States desiring to revise a plan are encouraged to verify and, in
many instances, expand the modeling and monitoring data supporting EPA's
findings.  In developing a suitable plan, it is suggested that States select
control strategies which place emissions for fuel combustion sources into
perspective with all sources of emissions such as smelters or other indus-
trial processes.  States are encouraged to consider the overall impact
which the potential  relaxation of overly restrictive emissions regulations
for combustion sources might have on their future control programs.   This
may include air quality maintenance, prevention of significant deterioration,
increased TSP, NOX,  and HC emissions which occur in fuel switching,  and other
potential air pollution situations such as sulfates.

     Although the enclosed analysis has attempted to address the attainment
of all  the NAAQS, most of the review has focused on total suspended  particu-
late matter (TSP) and sulfur dioxide (SC>2) emissions.  This is because sta-
tionary fuel  combustion sources constitute the greatest source of S02 emission
and are a major source of TSP emissions.

-------
     Part of each State's review was organized to provide an analysis of

the S02 and TSP emission tolerance within each of the various AQCR's.  The

regional emission tolerance estimate is, in many cases, EPA's only measure

of the "over-cleaning" accomplished by a SIP.  The tolerance assessments

have been combined in Section 2 and Appendix B with other regional air

quality "indicators" in an attempt to provide an evaluation of a region's

candidacy for changing emission limitation regulations.  In conjunction

with the regional analysis, a summary of the State's fuel combustion sources

(power plants, industrial sources, and area sources) has been carried put

in Appendices C, D, and E.


     The State Implementation Plan for the State of Connecticut has been

reviewed for the most prevalent causes of over-restrictive emissions lim-

iting regulations.  The major findings of the review are as follows:


     FOR S02, THE REVIEW INDICATES THAT SOME POTENTIAL EXISTS FOR
     REVISING CURRENT FUEL SULFUR CONTENT REGULATIONS IN THE EASTERN
     CONNECTICUT AND NORTHWESTERN CONNECTICUT INTRASTATE AQCR'S.


     FOR PARTICIPATES. THE REVIEW INDICATES THAT SOME POTENTIAL
     ETlSTS FOR REVISING EMISSION LIMITING REGULATIONS IN THE
     NORTHWESTERN CONNECTICUT AQCR.


     The supportive findings of the SIP review are as follows:


     Connecticut - The State of Connecticut has no air quality standard
     which is more stringent than any National Ambient Air Quality
     Standard and has not utilized the "example region" approach in
     developing its SIP.


     Eastern Connecticut Intrastate AQCR - Air quality violations, no to.l-
   .  erance for an emission increase and modeling results for one major
     power plant indicate that little potential  exists for revising parti-
     culate emission limiting regulations at the present time.   Some poten-
     tial  exists for revising sulfur content regulations based on air qua-
     lity although modeling results  for the major power plant were negative
     for the conversion modeled.   Further research of the circumstances
     would be needed.

populated.
Northwest Connecticut Interstate AQCR - Air quality data indicate
that some potential exists for revising both particulate and sulfur
dioxide'emission limiting regulations though no modeling was avail-
able.  Clean fuel savings may be limited, however,  since major point
sources are few.  Some clean fuel savings may result from revision
of area source emission regulations but these will  probably  not be
significant.

                   2.0  STATE IMPLEMENTATION PLAN REVIEW

2.1  SUMMARY
     A revision of fuel combustion source emissions regulations will depend
on many factors.  For example:
     •  Does the State have air quality standards which are more stringent
        than NAAQS?
     t  Does the State have emission limitation regulations for control of
        (1) power plants, (2) industrial sources, (3) area sources?
     •  Did the State use an example region approach for demonstrating the
        attainment of NAAQS p_r more stringent State standards?
     •  Has the State not initiated action to modify combustion source
        emission regulations for fuel savings; i.e., under the Clean Fuels
        Policy?
     •  Are there no proposed Air Quality Maintenance Areas?
     •  Are there indications of a sufficient number of monitoring sites
        within a region?
     t  Is there an expected 1975 attainment date for NAAQS?
     •  Based on (1973) air quality data, are there no reported violations
        of NAAQS?
     •  Based on (1973) air quality data, are there indications of a toler-
        ance for increasing emissions?
     •  Are the total emissions from stationary fuel combustion sources
        proportionally lower than those of other sources?
     t  Is there a significant clean fuels savings potential in the region?
     •  Do modeling results for specific fuel combustion sources show a
        potential for a regulation revision?
     The following portion of this report is directed at answering these
questions.  An AQCR's potential for revising regulations increases when there
are affirmative responses to the above.

     The initial part of the SIP review report, Section 2 and Appendix A,
was organized to provide the background and current situation information
for the State Implementation Plan.  Section 3 and the remaining Appendices

-------
provide an AQCR analysis which helps establish the overall potential for
revising regulations.  Emission tolerance estimates have been combined in
Appendix B with other regional air quality "indicators" in an attempt to
provide an evaluation of a region's candidacy for revising emission limiting
regulations.  In conjunction with the regional analysis, a characterization
of the State's fuel combustion sources (power plants, industrial sources,
and area sources) has been carried out in Appendices C, D, E.

     Based on an overall evaluation of EPA's current information, AQCR's
have been classified as good, marginal, or poor candidates for regulation
revisions.  Table 2-1 summarizes the State Implementation Plan Review.
The remaining portion of the report supports this summary with explanations.


     The main factor in determining the candidacy for regulation revi-
sion is the air quality status.  Any AQCR which has an air quality vio-
lation is automatically given a poor rating.  On the other hand, a re-
gion with no air quality violations, no AQMA designations, low to mode-
rate emissions, along with a small percentage of emissions from fuel com-
bustion sources, would receive a good rating.  Those AQCR's that have
varying indicators would need further evaluation and would be given a
marginal rating.
2.2  CURRENT AIR QUALITY STATUS OF CONNECTICUT
2.2.1  Definition Of Air Quality Control Regions
     The State of Connecticut is comprised of four Air Quality Control
Regions (AQCR's), two intrastate and two interstate.   These are listed
below:
     •  Eastern Connecticut Intrastate - AQCR 41
     •  Hartford - New Haven - Springfield Interstate (Mass) - AQCR 42
     •  New Jersey - New York - Connecticut Interstate - AQCR 43
     •  Northwestern Connecticut Intrastate - AQCR 44

     Figure 2-1 illustrates the geographic boundaries of the Connecticut
portions of these AQCR's.

2.2.4  Emissions of Sulfur Dioxide and Particulates
     The contributions of fuel combustion sources located in Connecticut
to the total emissions in each AQCR are summarized 'in Table A-6 for both
TSP and SO,,.  Tables A-7 and A-8 provide a more detailed view by means of
categorization in terms of combustion source type, i.e., electricity gener-
ation, industrial-commercial-institutional, and area.  In general,  fuel
combustion sources account for a majority of the particulate (56%)  and S02
emissions (86%) in the State of Connecticut.
  2.3   GENERAL  REVIEW  OF  THE  CURRENT STATE  IMPLEMENTATION PLAN
       The  Connecticut State  Implementation Plan contained control strate-
  gies  and  regulations for both particulate and sulfur dioxide which will
  be adequate enough to attain State air quality standards which are the
  same  as the Federal  Standards.  The State did not utilize the example
  region approach  in formulating its SIP.

       The  state  regulations  for the control  of particulate matter include  a
  requirement  that existing  fuel burning sources cannot  emit  particulate
  matter in excess of  0.20  pounds per million BTU  of  heat input and  0.10
  pounds per million BTU  of  heat input  for  new sources  (Table A-9).  The
  state also has  a visible  emission  regulation which  says that no person  shall
  exceed No. 1  on the  Ringleman Chart or 20 percent opacity except for  periods
  aggregating  not more than  5 minutes in any  60 minutes  provided they still
  do not exceed No.  2  on  the  Ringleman  Chart  or 40 percent opacity.  Other
  regulations  covering particulate emission are fugitive dust, incineration,
  process  industries - general, and  process industries  - specific  (iron
  cupolas,  asphalt plants,  foundries, and  concrete batching).

       The  State  regulations  for the control  of sulfur  compound emissions
  include  the  requirement that after April  1, 1973 no person  shall burn fuel
  which contains  sulfur in  excess of 0.5%  by  weight.  Other regulations
  include  controlling  sulfur compounds  from sulfuric  acid plants, sulfur
  recovery  plants, non-ferrous smelter  sulfite pulp mills, and other process
  sources.

2.2.2  Air Quality Standards
     A summary of the Federal and Connecticut air quality standards for particu-
lates and S02 is presented in Table A-2.   It should be noted that the standards
adopted by Connecticut are identical to the Federal standards for both
pollutants.

2.2.3  Air Quality Monitoring
     Connecticut air quality data for total suspended particulates (TSP)
and sulfur dioxide (SCL) are given in Tables A-4 and A-5 respectively.

     Air quality monitoring in the Eastern Connecticut AQCR consists  of six
stations for TSP and eight stations for S02 (eight 24 hr.  bubbler, no continuous
stations).  Monitoring data for 1973 indicated a violation of federal TSP
standards but no violations of S02 standards.

     In the Hartford-New Haven-Springfield Interstate AQCR, air quality
monitoring consists of 67 stations for TSP and 34 stations for S02 (25
24-hr, bubbler, 9 continuous stations).  Thirty-four of the TSP monitors,
17 of the 24-hour S02 monitors and 8 continuous S02 monitors are located in
Connecticut.  The monitoring data indicated violations of the federal stand-
ards for both TSP and S02-  The region has also been proposed as an Air Qua-
lity Maintenance Area (AQMA) for both pollutants.

     In the New Jersey-New York-Connecticut Interstate AQCR, air quality
monitoring consists of 166 stations for TSP and 118 stations for S02  (47
24-hr, bubbler, 71 continuous stations).   Seventeen of the TSP monitors,
17 of the 24-hour S02 monitors and 16 of the continuous S02 monitors  are
located in Connecticut.   Violations of the federal standards for both TSP
and S02 were reported and the region has  been proposed as an AQMA for both
pollutants.

     In the Northwestern Connecticut AQCR there were no violations of TSP
or SCL standards reported by the four TSP stations and the three S02  stations
(all 24-hr, bubbler, no continuous) in 1973.

                3.0  AIR QUALITY CONTROL REGION ASSESSMENTS

     The purpose of this section is to evaluate the available information
for the State of Connecticut and determine the feasibility of revisions
to the SIP which would result in clean fuel conservation.  The first sub-
section provides explanations of the methods used in making the regional
assessments.  Subsections 3.2 through 3.5 present the results of the appli-
cation of the criteria for each of the Connecticut AQCR's.

3.1  THE ASSESSMENT CRITERIA
     In determining the potential of the AQCR's in a state for emission
standard relaxation, a set of five evaluation criteria has been established:
     •  The Regional Indicators,
     •  Power Plant Evaluation,
     t  Other Major Fuel Burning Point Source Evaluation,
     •  Area Source Evaluation,
     t  Fuel Use Assessment.
     The following paragraphs provide explanations of the use of these
criteria.

3.1.1  The Regional Evaluation
     This assessment is based on a review of regional air quality data,
various regional or subregional categorizations (e.g., priority classifi-
cations or proposed air quality maintenance area (AQMA) designations), and
other information available to EPA.  The assessment must be made for each
pollutant separately and is made on the basis of 7 indicators:  (1) recent
air quality violations; (2) expected NAAQS attainment dates; (3) proposed
Air Quality Maintenance Area (AQMA) designations; (4) total emissions; (5)
portion of emissions from fuel combustion sources in Connecticut; (6) regional
tolerance for emission increase; and (7) S02 priority classification.  Tables
B-l and B-2 tabulate these criteria for each AQCR for TSP and SO-, respectively.
This preliminary analysis will be supplemented by a more detailed evaluation
after the individual source categories are reviewed.

3.1.2 . Power Plant Evaluation
     The evaluation of power plants was based on the modeling analyses per-
                         12        3
formed by Walden Research  '  and EPA .  Both assumed certain oil-to-coal conver-
sions for some of the power plants in Connecticut and then performed plant-
by-plant diffusion modeling to determine the air quality impacts of the
plants, before and after conversion.  The power plant data appear in
Appendix C:  Table C-l summarizes pertinent data by plant,including
fuel use and emissions; Table C-2 summarizes these data for each AQCR; and
Table C-3 lists the projected 1975 capacity and fuel use for the major
plants in each AQCR.

3.1.3  Major Industrial and Commercial Point Source Evaluation
     No modeling results were available for the larger industrial, commer-
cial, or institutional point sources in Connecticut.  Consequently, the
analysis was restricted to an estimate of the emissions reduction resulting
from the compliance of these sources with current Connecticut emission and
fuel regulations.  The results appear in Appendix D.

3.1.4  Area Source Evaluation
                                                      4
     Area source emissions data were available by AQCR  and by county from
the National Emissions Data System (NEDS).   These data were used to determine
the emissions from Connecticut fuel combustion area sources which are given
in Appendix E.  Table E-l indicates the types of fuel burned by fuel com-
bustion area sources, sulfur contents and emissions by AQCR.

3.1.5  Fuels Analysis
     Fuel usage data for the State of Connecticut are tabulated in Appendix
F.  These data provide a survey of the distribution of fuels by user type
for the entire state, as well as by AQCR.  The data is fundamentally impor-
tant to potential clean fuel savings which  will be significant in a region
which can tolerate a regulation revision only if a significant amount of
fuel is burned in the region.  The data has its shortcomings however, be-
cause the data for the Interstate AQCR.'s are for the entire AQCR rather than
the Connecticut portion of the AQCR.

3.2  EASTERN CONNECTICUT INTRASTATE AQCR 41
3.2.1  Regional  Assessment (Appendix B)
     The regional evaluation of the Eastern  Connecticut AQCR indicates
that little potential exists for increasing  particulate emissions but some
potential exists for increasing SOp emissions.   The indicators are sum-
marized below:
     •  Particulates - one reported air quality violation and no
        tolerance for emission increase.
     •  Sulfur Dioxide - no air quality violations, no proposed
        AQMA designations and a positive tolerance for emission
        increase.
     Tables B-l  and B-2 list the indicators  by  AQCR for TSP and S02,
respectively.

3.2.2  Power Plant Assessment (Appendix C)
     NEDS data indicate the existence of six power plants in the Eastern
Connecticut AQCR.  Together, they account for approximately 22 percent
and 61 percent of the particulate and sulfur dioxide emissions within the
AQCR, respectively.  Three of the six plants; those at Preston, Killingly,
and Putnam, are gas turbine plants burning distillate oil, and contribu-
ting almost negligible amounts of particulates  and SOo.  Of the three
steam turbine generating plants, two are very small and also contribute
negligible amounts of pollution.  These two  are the plant at New London
burning liquid petroleum gas (LPG) and the plant at Waterford burning a
small quantity of residual oil.  The only major plant in the region is the
600 megawatt plant at Montville which burns  significant amounts of both
coal and residual oil, and small amounts of  distillate and diesel oil;
the diesel in a reciprocating diesel engine.  All  six plants are opera-
ted by Connecticut Light and Power.

     A fuel  conversion was modeled by Wai den Research for the Montville
plant.  According to the analysis, units 1, 2 and 5 of the plant's six
                                    15

-------
units are convertible to coal.  These units are rated at 34.5, 34.5 and 82

MW, respectively.  The modeling results indicated that currently the plant,
                                                  o
burning .9% sulfur oil, contributes about 128 yg/m  to the 24-hour S0? con-
                            3
centrations and about 7 yg/m  to the 24-hour TSP concentrations.  The anal-

ysis was based on 1972 data and is limited to 24-hour concentrations because

a special diffusion model suited to the valley topography was utilized.  If

units 1, 2 and 5 were converted to 3.0% sulfur, 15% ash coal, and op-

erating at 80% control efficiency, the modeling results indicated that

the plant would  contribute about 460 yg/m3 to the 24-hour SOg concen-

trations and about 191 yg/m3  to the 24-hour TSP concentrations, vio-

lating the federal primary S0? standard and secondary TSP standard.

The results of the modeling are given below in Table 3-1:

 Nominal Load Case - This presents maximum concentrations calculated
 by the model based upon average monthly emission rates.

''Maximum Load Case - This case was calculated assuming the plant to
 be operating at 95% of rated capacity.  Concentrations were pre-
 dicted for the 20 highest concentration days under nominal load.
 A 10% safety factor was subsequently added to these predicted con-
 centrations because the maximum load case involves a greater plume
 rise, and a somewhat higher concentration may therefore occur on a
 different day and at a different receptor.
                                    16

-------
     In addition, on the basis of other preliminary modeling, EPA did

not advise conversion of the Montville plant to coal firing for the
following reasons:

     The river valley topography, in which the plant is situated,
     severely limits effective dispersion of emissions from the
     Montville stacks.  Consequently, there is a strong likelihood
     of a significant impact from increased emissions in the cities
     of Norwich and New London, Connecticut.  Though presently
     below the primary standards, air quality in these areas is not
     sufficiently good to be able to absorb a substantial  increase
     in emissions without a sizeable risk of violating the primary
     standards.  Furthermore, the age and original  design  efficiency
     of existing particulate control equipment does not warrant
     belief that a reasonable degree of particulate collection can
     be obtained while operating on coal.  Lastly,  since it is deemed
     impossible to retrofit flue gas desulfurization equipment at the
     Montville plant, it is unlikely that the plant could  ever be
     brought into compliance with Connecticut emission regulations.

     In summary, the Montville plant is not recommended for conversion  to
coal, at least not the conversion modeled.


3.2.3  Major Industrial and Commercial Point Source Assessment (Appendix D)

     Since no modeling was available for industrial and commercial point

sources, the analysis was limited to a comparison of the current emissions

and the allowable emissions for these sources.
     As indicated in Tables A-7 and A-8, industrial  and commercial  point

sources contribute approximately  7 percent to the particulate emissions

and 14 percent to the SCL emissions from fuel  combustion sources  in the

Eastern Connecticut Intrastate AQCR.  Table D-l  lists one significant

industrial/commercial point source in the AQCR for particulates;  Table

D-2 lists 5 significant sources for SOp.  These  significant  sources ac-

count for about 6 percent and 14 percent of the  AQCR fuel combustion

particulate and SOp emissions, respectively.   Table  D-3 summarizes  the

current emissions and potential emission reductions  for the  AQCR  indicating

that existing regulations might allow an increase in particulate  emissions

from industrial and commercial sources.   However, air quality data  for the

AQCR indicates that this would not be possible.
                                    17

-------
3.2.4  Area Source Assessment (Appendix E)
       Area fuel combustion sources contribute significantly to the par-
ticulate and sulfur dioxide emissions in the Eastern Connecticut Intra-
state AQCR.  Tables A-6 and A-7 indicate that they represent the source
of about 30 percent and 23 percent of the particulate and sulfur dioxide
emissions, respectively.  Table E-l shows area fuel combustion sources
burn coal, oil, natural gas and wood with oil burning accounting for the
majority of emissions.  It is unlikely, however, that these sources
could convert from oil or gas to coal in light of the AQCR particulate
problem and the inherent inflexibility of these sources to convert.
Some clean fuel savings may result from increasing sulfur contents but
it is unlikely to be a significant amount.

3.3    HARTFORD-NEW HAVEN-SPRINGFIELD INTERSTATE AQCR 42
3.3.1  Regional Assessment (Appendix B)
       The regional evaluation of the Hartford-New Haven-Springfield AQCR
indicated that little potential  exists for increasing either particulate
or S02 emissions.  The supportive indicators are as follows:
       t  Particulates - reported air quality violations, proposed
          AQMA designations and no tolerance for emission increase.
       •  Sulfur Dioxide - reported air quality violations, proposed
          AQMA designations and no tolerance for emission increase.
       Tables B-l and B-2 list these .indicators by AQCR for TSP and S02,
respectively.

3.3.2  Power Plant Assessment (Appendix C)
       Ten power plants are listed in the NEDS data for the Connecticut
portion of the Hartford-New Haven-Springfield Interstate AQCR.   Connecti-
cut Power and Light operates a very small  LPG fired plant at Berlin, two
small distillate oil  fired gas turbine plants  at Enfield and Branford, a
small residual oil and natural gas fired plant at Waterbury, and a plant
at Thompsonville which has one distillate oil and natural gas boiler, and
one gas turbine also using distillate oil  and natural gas.  The emissions
of both particulates and S02 are less than 100 tons per year for each of
these five plants.
                                 18

-------
     The remaining five plants in the region each emit more than TOO tons
per year of SO^.  They are:  Hartford Electric's 220 megawatt South
Meadow plant and 420 megawatt Middletown plant, both of which have
residual oil fired boilers and distillate oil fired gas turbines; United
Illuminating Company's 20 megawatt Derby plant and 160 megawatt English
plant, both using residual oil fired boilers; and Connecticut Light and
Power's Devon plant which burns coal, residual and distillate oil as
boiler fuel, and distillate oil in a gas turbine.

     Collectively, the ten power plants contribute approximately 6 per-
cent and 34 percent to the particulate and sulfur dioxide emissions in
the Connecticut portion of the AQCR, respectively.

     Preliminary modeling of a fuel conversion was done by EPA for the
Hartford Electric Company's Middletown plant.  The plant consists of three
units, two of which are convertible to coal.  Concentrations estimated by
the modeling indicated that changing units 1 and 2 from .5% sulfur oil to
a maximum of 2.5% sulfur coal and keeping unit 3 on a .5% sulfur oil would
result in contributions to 24-hour S02 concentrations of 160 yg/m3, an
increase of about 130 yg/m3 over the oil case.  Particulate concentrations
would be about 40 yg/m3 with 15% ash and 90% control.  Actual concen-
trations may be higher due to the effects of the river valley topography
in which the plant is located.  These terrain effects are not taken into
account in the model.  No conclusions can be drawn from this modeling be-
cause of the terrain effects and the lack of air quality data in areas
immediately around the plant.  Any conversion would require increased mon-
itoring and high levels of control.

3.3.3  Major Industrial and Commercial Point Source Assessment (Appendix D)
     As previously mentioned, no modeling data were available for indus-
trial and commercial point sources, therefore the analysis was limited
to a comparison of the current emissions and the allowable emissions for
these sources.  As indicated in Tables A-7 and A-8, industrial and com-
mercial point sources contribute approximately 12 percent to the parti-
culate emissions and 27 percent to the S02 emissions in the Hartford-New
                                    19

-------
Haven-Springfield Interstate AQCR.  Table D-l lists one significant
industrial/commercial point source in the AQCR for participates;
Table D-2 lists 26 significant sources for S02>   These significant
sources account for about 1 percent and 8 percent of the AQCR fuel
combustion particulate and SOp emissions, respectively.  Table D-3
summarizes current emissions and potential emission reductions, in-
dicating that existing regulations might allow a slight increase in
particulate emissions from industrial and commercial sources.  How-
ever, air quality data for the AQCR indicate that this would not be
feasible.

3.3.4  Area Source Assessment (Appendix E)
     Area fuel combustion sources in the Hartford-New Haven-Spring-
field AQCR account for approximately 41 percent  of the particulate
emissions and 36 percent of the sulfur dioxide emissions.   Table E-l
shows fuel use for area sources in the AQCR and  indicates  that oil
is the major fuel used.  It is unlikely that these sources could con-
vert from oil to coal because of the inherent lack of flexibility of
the sources themselves and the AQCR particulate  problem.   It is un-
likely that higher sulfur oil  could be used because of the S02 pro-
blem.

3.4  NEW JERSEY-NEW YORK-CONNECTICUT INTERSTATE  AQCR 43
3.4.1  Regional Assessment (Appendix B)
       The regional  evaluation of the New Jersey-New York-Connecticut
AQCR indicates little potential  for increasing particulate or sulfur
dioxide emissions based on 1973 air quality data.  The indicators are
summarized below:
       •  Particulates - reported air quality violations,  proposed
          AQMA designations and no tolerance for an emission increase.
       •  Sulfur Dioxide - reported air quality  violations, proposed
          AQMA designations and no tolerance for an emission increase.
       Tables B-l and B-2 list these indicators  by AQCR for TSP and
S02, respectively.
                                 20

-------
3.4.2  Power Plant Assessment (Appendix C)
     Of the four power plants in the Connecticut portion of the New Jersey-
New York-Connecticut AQCR, three emit a significant amount of SO^;  Two
of these, the 170 megawatt Steel Point plant and the 650 megawatt Bridge-
port Harbor plant burn residual oil and are operated by United Illuminating
Co.  The third, Connecticut Light and Power's Norwalk Harbor plant has a
capacity of 325 megawatts and burns coal, residual and distillate oil  in
boilers, plus a small quantity of deisel fuel in a reciprocating engine
generator.  The fourth plant is a small distillate oil fired gas turbine
plant operated by Connecticut Light and Power at Greenwich.

     Jointly, the four plants contribute approximately 43 percent to the
particulate emissions and 68 percent to the sulfur dioxide emissions in
the AQCR.

     A fuel conversion was modeled by Wai den Research for Connecticut  Light
and Power Norwalk Harbor plant.  The results (shown in Table 3-2) indicated
                                                                           o
that presently the plant, burning .8% sulfur oil, contribures about 23 yg/m
to local 24-hour S02 concentrations and about 1  yg/m  to local  24-hour
TSP concentrations.

     Converting Units 1 and 2 to 2.5% sulfur, 15% ash coal, and operating
at 95% control efficiency yielded local 24-hour  concentrations  of 96 yg/m3
and 13 yg/m3 for S02 and TSP, respectively.

-------
     Preliminary modeling performed by EPA indicated similar results.  Using
 .5% sulfur oil the plant contributed about 15 yg/m3 to local 24-hour S00
                         3
 concentrations and 2 yg/m  to local 24-hour TSP concentrations.  Converting
 the two  units to 2.5% sulfur, 15% ash coal and operating at 95% control
 efficiency would result in local 24-hour concentrations of approximately 110
 yg/m3 of S02 and 15 yg/m3 of TSP.

     Other factors were considered by the Connecticut Department of
 Environmental Protection which estimated on an annual basis, combustion of
 2.5% sulfur coal in units 1 and 2 would result in an incremental impact
 of S02 of 17 yg/m3.

     Existing annual S09 averages in nearby areas range from 50 to 70
    3
 yg/m .   The incremental inpact in particulates of burning 15% ash coal
 would be approximately 8 yg/m .   Annual  background TSP concentration in
                                     3
 the area of maximum impact is 80 yg/m .   By these modeling results, the
 annual primary standards for TSP and SOp would probably be violated by
 conversion of the Norwalk Harbor plant to coal.   Furthermore, the plant
 is located in a densely populated region of Connecticut and conversion
 to coal would exacerbate an existing TSP problem.

 3.4.3  Major Industrial and Commercial  Point Source Assessment  (Appendix  D)
     Since no modeling data were available  for industrial  and commercial
point sources, the analysis was  limited  to  a comparison of the  current
emissions and the allowable emissions  for these  sources.   As  indicated  in
Tables A-7 and A-8, industrial  and commercial  point sources contribute
 approximately 2 percent to the  particulate  emissions  and 3 percent  to the
S02 emissions in the New Jersey-New York-Connecticut  Interstate AQCR.
Table D-l lists no significant  industrial/commercial  point source  in
the AQCR for particulates;  Table D-2 lists  5 significant sources for
S02.  These significant sources  account  for about 2 percent of  the  AQCR
 fuel combustion S02 emissions.   Table  D-3 summarizes  current emissions
 and potential emission reductions indicating that existing regulations
 do not allow any increase in either particulate  or S02 emissions.
                                      22

-------
emissions for these sources.  As indicated in Table A-7 and A-8, indus-
trial and commercial point sources contribute approximately 6 percent to
the particulate emissions and 10 percent to the SO  emissions in the
Northwestern Connecticut Intrastate AQCR.  Table D-l lists no significant
industrial/commercial point sources in the AQCR for particulates; Table
D-2 lists 1  significant source for SOp.  This significant source accounts
for about 7 percent of the AQCR fuel combustion SOp emissions!  Table D-3
summarizes the current emissions and potential emission reductions for
the AQCR indicating no potential for increasing emissions under the exis-
ting regulations.

3.5.4  Area Source Assessment (Appendix E)
       Area fuel combustion sources account for 67 percent of the parti-
culate emissions and 84 percent of the sulfur dioxide emissions in the
Northwestern Connecticut AQCR.  However, total emissions for the AQCR
are relatively low and conversion from oil to coal is not very practical
for these sources.  Some clean fuel savings may result from increasing
sulfur contents but it is unlikely to be a significant amount.
                                 24

-------
3.4.4  Area Source Assessment  (Appendix E)
       Area fuel combustion sources contribute approximately 38 percent
and 26 percent to the particulate and sulfur dioxide emissions in the
New Jersey-New York-Connecticut AQCR, respectively (Tables A-6 and A-7).
Table E-l shows fuel use for area sources in the AQCR.  Conversions are
unlikely because of the TSP and SCk problems, and the inflexible nature
of the sources involved.

3.5  NORTHWESTERN CONNECTICUT INTRASTATE AQCR 44
3.5.1  Regional Assessment (Appendix B)
        The regional evaluation for the Northwestern  Connecticut AQCR
indicates that some potential  exists for increasing particulate and sulfur
dioxide emissions.   The indicators are summarized below:
        •  Parti cul ates - no reported air quality violations,  no
           proposed AQMA designations and a tolerance for an
           emission increase.
        •  Sulfur Dioxide - no reported air quality violations,
           no proposed AQMA designations and a tolerance for  an
           emission increase.
        Tables B-l  and B-2 list these indicators  by AQCR for  TSP and
SOp,  respectively.

3.5.2  Power Plant  Assessment  (Appendix C)
        The only  power plants  in the Northwestern Connecticut  AQCR are  two
distillate oil gas  turbines operated by  Hartford Electric Co.  at Torrington.
These plants both emit less than 20  tons per year each  of particulates  and
SOp,  and therefore  are relatively insignificant sources.  Together,  they
account for approximately 3 percent  of the  particulate  emissions  and 1  per-
cent  of the SOp emissions from fuel  combustion sources.

3.5.3  Major Industrial  and Commercial  Point Source Assessment  (Appendix D)
        As previously  mentioned no modeling data  were available for
Connecticut industrial  and commercial  point sources,  therefore  the analysis
was limited to a comparison of the current  emissions  and the  allowable
                                    23

   In some cases fuel sulfur contents have changed between 1973 and  1974 though  complete fuel  use was not
   available for 1974.

a - All data for significant sources in Connecticut only.   Significant sources  are  those
    non-power-plant sources whose total plant emissions are greater than  100  tons per
    per year of the pollutant in question.   Sources are listed in  Tables  D-l  and D-2.
                     o                   c
b - Liquid fuel in 10  gallons, gas in 10  cubic feet.   All annual  rates.

c - NEDS data year of record 1971.  Emissions listed are those from sources which are
    significant emitters of the indicated pollutant, i.e.  particulate emission  values
    do not include particulate emissions from significant SOp  sources unless  a  source
    is a significant source of both pollutants.

16. ABSTRACT
       Section IV of  the  Energy Supply and  Environmental Coordination Act of 1974,
  (ESECA) requires EPA to review each State Implementation Plan  (SIP) to determine
  if revisions can be  made to control regulations for stationary fuel combustion
  sources without interfering with the attainment and maintenance of the national
  ambient air quality  standards.  This document, which is also required by Section
  IV of ESECA, is EPA's  report to the State indicating where  regulations might be
  revised.
