                                PREFACE

     This document reports revisions to the Standards  of Performance
for New Stationary Sources which have appeared in the  Federal  Register
since the publication of the first Interim Report (EPA 340/1-76-009)
on August 1, 1976.  The set of revisions included in this supplement  will
update it through March 15, 1977.
     Upon promulgation of the revised reference methods, proposed  June 8,
1976, a new handbook will  be printed in entirety.   The format  will  be
similar to the current handbook, but will  be designed  so that  later re-
visions can be added to the compilation without it being redone.

   Delegation of Authority to  State  of Cali-

   '  Pollution Control District
     Pursuant to the delegation of authority
   for the standards of performance for new
   stationary sources (NSPS)  to the State
   of California on  behalf of  the  Madera
   County  Air Pollution  Control District,
   dated May 12,1976, EPA is today amend-
   ing 40 CFR 60.4 Address, to reflect this
   delegation. A Notice announcing this del-
   egation is published in the  Notices Sec-
   tion of this issue of the FEDERAL REGISTER,
   Environmental  Protection Agency, FRL
   596-8. The amended 5 60.4 is set forth be-
   low. It adds the address of the  Madera
   County Air Pollution Control District, to
   which must be addressed all reports, re-
   quests,   applications,   submittals,  and
   communications pursuant to this part by
   sources  subject to the  NSPS  located
   within this Air Pollution Control District.
     The Administrator finds good cause for
   foregoing  prior public  notice and  for
   making this rulemaking effective immed-
   iately  in that  it  is an administrative
   change and not one of substantive con-
   tent. No additional substantive burdens
   are imposed on  the parties affected. The
   delegation which is reflected by this ad-
   ministrative amendment was effective on
   May 12.  1976. and it serves no purpose to
   delay the technical change  of this addi-
   tion of the Air Pollution Control District
   address   to  the  Code   of   Federal
   Regulations.
     This  rulemaking is effective immedi-
   ately, and is issued under  the authority
   of Section  111 of the Clean Air Act,  as
   amended 142 U.S.C. 1857c-6L

 PART  60— STANDARDS  OF  PERFORM-
 ANCE  FOR NEW  STATIONARY SOURCES
      Revision to Emission Monitoring
              Requirements
   On  October  6,  1975 (40 PR 46250),
 under  section 111 of the Clean Air Act,
 as amended, the  Environmental Protec-
 tion Agency  (EPA)  promulgated emis-
 sion monitoring requirements and revi-
 sions to the performance testing methods
 In 40  CFB Part 60.  The  provisions of
 f60.13(i)   allow  the  Administrator  to
 approve alternatives to monitoring pro-
 cedures or requirements only upon writ-
 ten application by an owner or operator
 of an affected facility; monitoring equip-
 ment  manufacturers would not be al-
 lowed to apply for approval of alternative
 monitoring equipment. Since EPA  did
 not Intend to prevent monitoring equip-
 ment manufacturers  from  applying for
 approval   of  alternative  monitoring
 equipment, 5 60.13(1) is being revised. As
 revised, any person will  be allowed to
 make  application to  the  Administrator
 for approval of  alternative monitoring
 procedures or requirements.
   This revision does not add new require-
 ments, rather it  provides greater flexi-
 bility for  approval of alternative equip-
 ment and procedures. This revision is
 effective (date of publication).

  PART  60-^-STANDARDS  OF  PERFORM-
  ANCE FOR NEW STATIONARY SOURCES
         Amendments to Subpart D
    Standards of performance for fossil
  fuel-fired steam generators of more than
  73 megawatts (250 million Btu per hour)
  heat input rate are provided under Sub-
  part D of 40 CFR Part 60. Subpart D is
  amended herein to revise.the application
  of the standards of performance for fa-
  cilities burning wood residues in combi-
  nation with fossil fuel.
  Subpart D contains standards for par-
ticulate matter, sulfur dioxide, nitrogen
oxides, and visible emissions from steam
generators. These standards, except for
the one applicable to visible emissions,
are based on heat input. For sulfur di-
oxide, there are separate standards for
liquid fossil  fuel-fired  and  solid fossil
fuel-fired  facilities with provisions for a
prorated standard when combinations of
different fossil fuels are fired.  There Is
no sulfur  dioxide standard for gaseous
fossil fuel-fired facilities since they emit
negligible amounts of sulfur dioxide.
  To date, there have been two ways for
a source  owner or operator to comply
with the sulfur dioxide standard: (1) By
firing low sulfur fossil fuels or  (2) by
using flue gas desulfurization systems.
Complying with the standard  by firing
low  sulfur fossil fuel  requires an  ade-
quate supply of fuel with a sulfur con-
tent low enough to  meet the standard.
However,  it would be possible for the
owner or operator to fire, for example, &
relatively  high sulfur fossil fuel with &
very low sulfur fossil fuel (e.g. natural
gas) to obtain a  fuel  mixture which
would meet the standard. The low sulfur
fuel adds  to the heat input but not to
the sulfur dioxide emissions and, thereby,
has an overall fuel sulfur reduction ef-
fect. In the past, the application of Sub-
part D  permitted the heat  content of
fossil fuels but  not  wood residue to be
used in determining compliance with the
standards for participate matter, sulfur
dioxide and nitrogen oxides: the amend-
ment made herein will  allow  the  heat
content of wood residue to be used for
determining compliance with the stand-
ards. The amendment does not change
the scope of applicability of Subpart D:
all  steam generating units constructed
after August 17. 1971, and capable of fir-
ing fossil fuel at a heat input rate of
more than 73 megawatts (250 million Btu
per hour) are subject to Subpart D.
     RATIONALE FOR THE AMENDMENTS
  Wood  residue, which includes bark.
sawdust, chips,  etc.. is not a fossil fuel
and thus has not been allowed for use as
& dilution agent in  complying with the
sulfur dioxide standard for steam gener-
ators. Several companies have requested
that EPA revise Subpart D to permit
blending of wood residue with high sulfur
fossil fuels.  This would enable them to
obtain a fuel mixture low enough in sul-
fur  to comply with  the  sulfur dioxide
standard. Since  Subpart D allows the
blending  of high and low sulfur fossil
fuels, EPA has concluded that It is rea-
sonable to  extend  application of  this
principle to wood residue which, although
not  a fossil fuel, does have low  sulfur
content.
  Several companies have expressed in-
terest in  constructing steam generators
which continuously  fire wood residue In
combination with fossil fuel. New facili-
ties will comply with the standards for
less cost  than at present because they0
will be able to use wood residue, a valu-
able source of energy, as an alternative to
expense  low  sulfur fossil fuels.  Also,
using wood residue as a fuel supplement
Instead  of low sulfur fossil fuels will re-
                                                      IV-151

suit in substantial savings In the con-
sumption of scarce'natural gas and oil
resources, and will-"relieve what would
otherwise be a  substantial solid waste
disposal problem. Consumption of energy
and raw material resources will be re-
duced  further by  minimizing the need
for flue  gas  desulfurization systems  at
new facilities. There will be no adverse
environmental impact; neither sulfur di-
oxide nor nitrogen oxides emissions will
Increase as a result of this action. Con-
sidering  the beneficial,  environmental,
energy, and economic impacts, it Is rea-
sonable to permit wood residue to be fired
as a low sulfur fuel to aid In compliance
with the standards for fossil fuel-fired
steam generators.
  In making this amendment, EPA rec-
ognizes  that affected  facilities which
burn  substantially more wood residue
than fossil fuel may have difficulty com-
plying with the 43 nanogram per Joule
standard for  paniculate matter (0.1
pound per million Btu). There is not
sufficient information  available at this
time to determine what level of particu-
late matter emissions is achievable; how-
ever, EPA Is continuing to gather infor-
mation on this  question. If EPA deter-
mines that the particulate matter stand-
ard   is  not , achievable,  appropriate
changes  will be made to the standard.
Any change would be proposed for pub-
lic comment; however, in the  interim,
owners and operators will be subject to
the 43 nanogram per joule standard.
       'F' FACTOR DETERMINATION

  New facilities firing wood residue  in
combination  with fossil fuel will be sub-
ject to the emission and fuel monitoring
requirements  of  § 60.45  (as  revised on
October  6, 1975, 40 FR 46250). The 'F'
factors listed in ? 60.45(f) (4), which are
used for converting continuous monitor-
Ing data and performance test data into
units of the standard, presently  apply
only to  fossil fuels. Therefore.  'F' fac-
tors for bark and wood residue have been
added to 5 60.45(f) (4). Any owner or op-
erator who elects to  calculate his own
'F* factor must obtain approval of the
Administrator.
    INTERNATIONAL SYSTEM OF UNITS

  In accordance with the objective  to
implement national use of the metric sys-
tem, EPA  presents numerical' values in
both metric units and English units  in
its  regulations  and technical  publica-
tions. In an effort to simplify use of the
metric unJts of measurements. EPA now
uses the International System of  Units
(SI) as set forth in a publication by the
American Society for  Testing and Ma-
terials  entitled "Standard for Metric
Practice" (Designation:  E 380-76). The
following amendments to Subpart  D re-
flect the use of SI units.
            MISCELLANEOUS

  Since  these amendments are expected
to have limited applicability, no environ-
mental impact statement is required for
this rulemaking pursuant to section Kb)
of the "Procedures for  the Voluntary
Preparation of  Environmental  Impact
Statements" (39 FR 37419).
  This action is effective on November 22,
1976. The Agency finds that good cause
exists for not publishing this action as a
notice of proposed rulemaking  and for
making  it effective immediately upon
publication because:
  1. The action is expected to have lim-
ited applicability.
  2. The action will remove  an  existing
restriction  on   operations without  in-
creasing emissions and will have benefi-
cial environmental, energy,  and eco-
nomic effects.
  3. The action is not  technically con-
troversial and does not alter the overall
substantive content of Subpart D.
  4. Immediate effectiveness of the action
will enable affected parties  to  proceed
promptly and with certainty in conduct-
ing their affairs.

   PART 60—STANDARDS OF  PERFORM-
 ANCE  FOR NEW STATIONARY SOURCES
   Amendments to Reference Methods 13A
                 and.138

   On  August 6, 1975 (40 FR 33151), the
 Environmental Protection Agency (EPA)
 Promulgated Reference Methods 13A and
•  1SB In Appendix A to 40 CPB Part 60.
 Methods 13A and 13B prescribe testing
 and  analysis  procedures for  fluoride
 emissions from stationary sources.  After
 promulgation of the methods, EPA con-
 tinued to evaluate them and as a result
 has determined  the need  for certain
 amendments to Improve the  accuracy
 and precision of the methods.
   Methods 13A and 13B require assembly
 of  the fluoride sampling train so that
 the filter is located either between the
 .third  and fourth impingers or In  an
 optional  location between the probe and
 first impinger. They also specify that a
 fritted glass disc be used to support the
 filter.  Since promulgation of the meth-
 ods. EPA has found that when a  glass
 frit filter support is used In the optional
 filter  location,  some  of  the  fluoride
 sample is retained on the glass. Although
 no tests  have been performed, it is be-
 lieved that fluoride  retention may also
 occur  if a sintered metal frit filter sup-
 port Is used. However, in tests performed
 using  a  20  mesh stainless  steel screen
 as  a filter support no fluoride retention
 was noted. Therefore, to eliminate the
 possibility of fluoride retention, sections
 5.1.5 and 7.1.3 of Methods 13A and 13B
 are being revised to require the use of
 a 20  mesh  stainless  steel screen  filter
 support if the filter is  located between
 the probe and first impinger. If the filter
 is located in the normal position between
 the third and fourth Impingers, the glass
  frit filter support may still be used.
   In addition to the changes to sections
 5.1.5 and 7.1.3. a few corrections are also
 being  made. The amendments promul-
 gated  herein are effective on November
  29, 1976. EPA finds that good cause exists
  for not publishing this action as a notice
 of  proposed rulemaking and for making
  it effective immediately upon publication
  because:
    RULES AND  REGULATIONS


  1.  The action is intended to improve
the accuracy and precision of Methods
13A  and  13B  and  does not  alter  the
overall substantive content of the meth-
ods  or  the stringency of standards of
performance for fluoride emissions.
  2.  The amended methods may be used
immediately in source testing for fluoride
emissions.

  Dated: November 17,1976.

support and a slllcone rubber gasket: neither
a glass frit filter support nor a sintered metal
filter support may be used If the filter Is In
front of the Impingers. If located between
the third and fourth Impingers, boroslllcate
glass with a glass  frit filter support and a
slllcone  rubber  gasket. Other materials of
construction may be used with approval from
the Administrator, e.g., If probe liner Is stain-
less steel, then filter holder may be stainless
steel. The holder design shall provide a posi-
tive seal against leakage from the outside or
around the filter.
  (c) Section  7.1.3  is amended by re-
vising the first two sentences of the sixth
paragraph to read as follows:
  7.1.3 Preparation of collection train. •  • •
  Assemble the train as shown  In Figure
13A-1 with the filter between the third and
fourth Impingers.  Alternatively,  the  filter
may be placed between the probe and  first
Impinger If a 20 mesh stainless steel screen
Is used for the filter support. •  •  •
     •       *       »       •       •
  (d)  In section  7.3.4, the reference in

   The amendments below institute cer-
tain  address  changes  for  reports  and
applications required from operators of
new sources. EPA has  delegated to  the
State  of North  Carolina authority  to
review  new and modified sources.  The
delegated authority includes the reviews
under 40 CFR Part 52 for the prevention
of significant  deterioration. It also  in-
cludes the reviews under  40 CPR Part 60
for  the standards of  performance  for
new stationary sources and  reviews un-
der 40 CFR Part 61 for national emission
standards for  hazardous air pollutants.
   A notice announcing .the delegation of
 authority is published elsewhere in this
. issue of  the FEDERAL  REGISTER.  These
 amendments provide that all reports, re-
 quests,   applications,   submittals.  and
 communications previously required for
 the  delegated reviews will now be  sent
 instead to the North Carolina Environ-
 mental  Management  Commission,  De-
 partment of Natural and Economic Re-

 agement, P.O. Box 27687, Raleigh. North

 ment was effective on November 24, 1976,

 technical change of this addition of the
 State address to the  Code of Federal

        NEW SOURCE  REVIEW
  Delegation of Authority to the State of
            South Carolina
  The  amendments  below institute cer-
tain address changes for reports and ap-
pllca.tions required from operators of new
sources. EPA has delegated  to the State
of South Carolina  authority to review
new and modified sources. The delegated
authority includes the reviews under 40
CFR Part 52 for the prevention of sig-
nificant deterioration.  It also  includes
the review under 40  CFR Part 60 for the
standards of performance for new sta-
tionary sources and review under 40 CFR
Part 61 for  national emission standards
for hazardous air pollutants.
  A notice announcing  the delegation of
authority is published  elsewhere in the
notices section of this issue of the FED-
ERAL REGISTER. These amendments pro-
vide that all reports, requests,  applica-
tions,  submittals, and  communications
previously  required  for  the delegated
reviews will  now be  sent to  the  Office of
Environmental Quality Control, Depart-
partment of Health and Environmental
Control,  2600  Bull  Street,  Columbia,
South  Carolina 29201.  instead of EPA's
Region IV.
  The   Regional Administrator  finds
good cause  for  foregoing  prior public
notice  and  for making this rulemaklng
effective Immediately In that It Is an ad-
ministrative change and not one of sub-
stantive comVi't. No additional substan-
tive burdens are Imposed on the parties
affected. The delegation which Is reflect-
ed  by  this  administrative  amendment
was effective on October  19,  and It
serves  no purpose to delay the technical
change of this addition of the State ad-
dress to the Code  of  Federal  Regula-
tions.
  This rulemaking  is effective  immedi-
ately, and is issued  under the authority
of sections  101, 110, 111. 112,  and  301
of the Clean Air Act, as  amended,  42

AIR  PROGRAMS—STANDARDS  OF  PER-
   FORMANCE   FOR  NEW  STATIONARY
   SOURCES
   Receipt of Application and Approval of
   Alternative Performance Test Method
   On January 26, 1976 (41 PR 3826), the
Environmental Protection Agency (EPA)
promulgated standards  of performance
for  new primary aluminum  reduction
plants under 40 CFR Part 60. The stand-
ards limit  air emissions of gaseous and
partlculate fluorides from new and modi-
fled primary aluminum reduction plants.
The owners or operators of affected  fa-
cilities are required  to  determine com-
pliance with these standards by conduct-
ing a performance test as specified in Ap-
pendix A—Reference Methods, Method
13A or  13B,  "Determination  of  Total
Fluoride  Emissions  from  Stationary
Sources" published in the FEDERAL REG-
ISTER August 6, 1975 (40 FR 33157). As
provided in 40 CFR 60.8(b), (2) and (3).
the Administrator may approve the use
of an equivalent test method or may ap-
prove the use of an  alternative method
if the method has been shown to be ade-
quate for the  determination of compli-
ance  with the  standard.  Method  13A
specified  that total  fluorides be deter-
mined by the  SPADNS Zirconium Lake
colormetric method, and  Method  13B
specified  that this determination be made
by the specific ion electrode method.
   On September 3, 1976, EPA received
•written application for approval of equiv-
alency for  a third analytical technique
from  Kaiser  Aluminum and Chemical
Corporation, Oakland, California. Specif-
ically, the application requested approv-
al of ASTM Method  D 3270-73T, "Ten-
tative Method of Analysis for Fluoride
Content  of the  Atmosphere and Plant
Tissues," 1974  Annual Book  of ASTM
Standards—Part 26.
  Specific guidelines  for the determina-
tion of method equivalency have not been
established by EPA.  However,  EPA has
completed a technical review of the ap-
plication  and has determined  that  the
ASTM method  will, produce results ad-
equate for the determination of compli-
ance with the standards of performance
for  new  primary   aluminum  plants.
Therefore,  EPA  approves  the ASTM
method as an alternative to the analyt-
ical procedures  specified in paragraph
7.3 "Analysis" of Method 13A or 13B for
aluminum plants, pursuant to 40 CFR
60.8(b)(3).

PART 60—STANDARDS OF PERFORMANCE
    FOR NEW STATIONARY  SOURCES
    Revisions to Emission Monitoring
  Requirements and to Reference Methods
  On  October  6, 1975  (40 FR 46250),
under sections  111, 114, and 301 of the
Clean Air  Act, as  amended, the Envi-
ronmental   Protection  Agency  (EPA)
promulgated emission  monitoring re-
quirements and revisions to the perform-
ance testing Reference Methods in  40
CFR Part 60. Since that time,  EPA has
determined  that  there is a need for a
number of .revisions to clarify  the re-
quirements. Each of the  revisions being
made in 40 CFR Part 60  are discussed
as follows:
  1. Section 60.13. Paragraph (c) (3) has
been rewritten  to clarify that  not only
new monitoring  systems  but  also up-
graded monitoring systems must comply
with applicable  performance  specifica-
tions.
  Paragraph (e) (1) is revised to provide
that data recording is not required more
frequently  than once every six minutes
(rather than the previously required ten
seconds) for continuous monitoring sys-
tems measuring the opacity of emissions.
Since reports) of excess emissions are
based upon review  of six-minute aver-
ages, more  frequent data  recording  is
not required in order to  satisfy  these
monitoring requirements.
  2. Section  60.45.  Paragraphs  (al
through  re> have been reorganized for
clarification. In addition, restrictions on
use of continuous monitoring systems for
measuring  oxygen on a wet basis have
been removed. Prior to this  revision, only
dry basis oxygen  monitoring equipment
was acceptable. Procedures for use of wet
basis oxygen monitoring equipment have
been approved  by EPA and were pub-
lished in the FEDERAL REGISTER as an al-
ternative procedure (41 FR 44838).
  Also deleted from § 60.45 are restric-
tions on the location of a carbon dioxide
(CO.)   continuous  monitoring system
downstream of wet scrubber flue gas de-
sulfurization equipment. At the time the
regulations  were i promulgated  (Octo-
ber 6. 1975). EPA thought that limestone
scrubbers were operated  under  condi-
tions  that  could  cause  significant gen-
eration or  absorption  of CO; by the
scrubbinc  solution  which  would cause
errors in the monitoring results. EPA in-
vestSeated  this potential  problem  and
concluded that lime or limestone scrub-
bers under  typical  conditions of opera-
tion do not significantly alter  the con-
centration  of CO-  in the  Hue gas and
would  not   introduce significant errors
into the monitorine results. Lime scrub-
bers ooerate at a pH level between 7 and
8 which will 'maximize SO; absorption
and minimize CO.. absorption. Thus, the
effect of CO: loss  on the emission results
is expected to be  minimal.  The  exact
amount of CO- loss, if any, during the
scrubber operation  has  not been deter -
      RULES AND  REGULATIONS

mined r,lnce II; Is dependent  upon l.lin
upcrallnK conditions lor a purtlculur fa-
cility. Although each percent of CO. ab-
sorption  will result  in a positive bias of
7.1 percent (at a  stack concentration of
14 percent CO?)  in the final emission
results, i.e. the indicated results may be
higher than actual stack concentrations,
the actual bias is expected to be very
small since the amount of CO: absorp-
tion will  be much less than one percent.
  In flue eases from limestone  scrubbers,
there exists a possibility of the addition
of CO* from  the scrubbing reaction to
the CO= from the fuel combustion. Every
two molecules of SO2 reacting with the
limestone will produce a molecule of CO:.
Limestone scrubbers are typically  oper-
ated at an approximate temperature of
50° C under acidic  conditions. At  these
operating conditions the amount of CO,
generated  in a  90  percent  efficiency
scrubber  is 1350  ppm or 0.135 percent
CO5. This will introduce a negative bias
of 1 to 1.5 percent for a CO- level of 8 to
15 percent. This amount  of  potential
error  compares favorably with systems
previously  approved. Therefore, EPA is
removing the  restrictions which limited
the installation of  carbon  dioxide con-
tinuous monitoring systems to  a location
upstream of the scrubber.
  Several other revisions are being  made
to paragraphs (a),  'b), (c), and  (e) of
Subnart  D which imnrove the  clarity or
further define the intent of the regula-
tions. Paragraph  (rl)  has been reserved
for later  addition  of fuel monitoring pro-
visions,             .n
  3. Performance Specification I. Para-
graoh 6.2 has been rewritten  to clarify
requirements that must be met by con-
tinuous opacity monitor manufacturers.
Manufacturers must certify that at least
one analyzer from each month's produc-
tion was  tested and meets all  applicable
requirements.  If  any requirements are
not met, the production for the month
must  he resarnpled according to militarv
standard 105D (MTL-STD-105D) and re-
tested. Previously  the regulation  re-
quired that each  unit of production had
to be tested. Copies of  MIT^STD-in5D
may be purchased from the Superintend-
ent  of   Documents,  U.S.  Government
Printing  Office. Washinrrton. D.C. ?0402.
  4. Performance Specification 2. Figure
2-3 of Performance Specification 2 has
been  corrected to  properly define the
term "mean differences." The corrections
in the operations now conform with the
statistical  definitions of the  specifica-
tions.
  5. General.  These  amendments pro-
vide optional monitoring procedures that
may be selected by an owner or operator
of a facility affected by the monitoring
requirements of 40 CFR Part 60. Certain
editorial  clarifications are also included.
Proposal   of  these  amendments is not
necessary because the changes  are either
interpretative in nature, or  represent
minor changes in instrumentation test-
ing and data recording, or allow a  wider
selection of equipment to be used. These
changes  will  have  no effect  upon the
number of emission sources that must be
monitored or the  quality of the resultant
emission data. Tho channel arc consist-
ent with  recent determinations of the
Administrator with respect to use of al-
ternative continuous monitoring systems.
  6. Effective  date. These  revisions be-
come effective March 2. 1977.

Subpart D—Standards of .Performance for
   Fossil Fuel-Fired Steam Generators
  2. Section 60.45 is amended by revising
paragraphs (a),  (b),  (c),and (e) and by
reserving paragraph  (d) as follows:
§ 60.45  Emission and fuel monitoring.
  (a) Each owner or operator shall in-
stall,  calibrate,  maintain,  and operate
continuous monitoring systems for meas-
uring the  opacity of emissions,  sulfur
dioxide emissions, nitrogen oxides emis-
sions, and  either oxygen or  carbon di-
oxide except  as  provided in  paragraph

-------
   (2) For B fossil Juel-flred steam gen-
erator that does not use a flue  gas  de-
sulfurization device, a continuous moni-
toring system  for measuring sulfur di-
oxide emissions  is not  required if  the
owner or operator monitors sulfur  di-
oxide emissions  by fuel sampling and
analysis under paragraph (d)  of  this
section.
   (3)  Notwithstanding  §60.13(to),  in-
stallation  of a  continuous monitoring
system  for nitrogen oxides may be  de~
layedttntil after the initial performance
tests under § 60.8 have  been conducted.
If the owner or operator demonstrates
during the performance test that emis-
sions of nitrogen oxides are less  than 70
percent of  the applicable standards in
8 60.44,  a continuous monitoring system
for measuring  nitrogen oxides emissions'
is not required. If the initial performance
test results show  that nitrogen  oxide
emissions are greater than 70 percent of
the  applicable standard, the  owner  or
operator shall install a continuous moni-
toring system for nitrogen oxides within
one year after the date of the initial per-
formance tests under  §  60.8 and comply
with all other applicable monitoring re-
quirements under this part.
   (4) If an owner or operator does not
install any continuous  monitoring sys-
tems for sulfur oxides and nitrogen ox-
Ides, as provided under paragraphs  (b)
(1)  and  (b)(3)  or paragraphs  (b) (2)
and (b) (3) of  this section  a continuous
monitoring system for measuring either
oxygen  or carbon dioxide is not required.

 STANDARDS OF PERFORMANCE FOR
      NEW STATIONARY SOURCES
Emission Guidelines for the Control of Sul-
  furic Acid Mist From  Existing  Sutfuric
  Acid Production Units
  The purpose of this notice is to propose
emission guidelines and  times for com-
pliance  for the  control of sulfurtc acid
mist emissions from existing sulfurlc acid
production units, and to announce  the
publication of  a draft guideline  docu-
ment concerning the control of  sulfuric
acid mist emissions from such units.
  The Clean Air Act (42 U.S.C. 1857 et
seq.)  as  amended, applies to three gen-
eral categories of pollutants emitted from
stationary sources.  The  first  category
consists  of pollutants (often referred to
as "criteria pollutants")  for which air
quality criteria and national ambient air
quality standards are established -under
sections 108 and 109 of the Act and which
are controlled by «tate implementation
plans under section 110. The second cate-
gory  consists of pollutants  listed and
controlled as hazardous pollutants under
section  112 of the Act. Toe third cate-
gory  consists of pollutants that may
cause or contribute to the endangerment
of public health or welfare but are  not
or cannot be controlled under  sections
108-110. or 112.  Section llKd)  acquires
control  of existing sources of such pol-
lutants whenever standards of perform-
ance (for those pollutants)  are estab-
lished under section  11Kb) for new
sources  of the same type. For  conven-
ience of reference, such  pollutants  are
referred to as "designated pollutants,"
and existing facilities whose emissions of
such pollutants must be controlled under
section lll(d) are referred to as "desig-
nated faculties."
  On November 17. 1075 (40 FR 53340).
EPA promulgated a new subpart B to
40 CFR  Part 60 establishing procedures
and requirements for submittal  of state
plans for control of designated pollutants
from designated facilities under section
lll(d). A summary of subpart B  and a
discussion of the basic concepts under-
lying It appear in the  preamble pub-.
Bshed In connection with its promulga-
tion. In brief,  subpart B provides that
after a standard of  performance  appli-
cable to emissions of a designated pol-
lutant from new sources is promulgated,
the  Administrator will publish  a draft
guideline document containing informa-
tion pertinent to the control of the same
pollutant from designated (i.e., existing)
facilities. He will also publish a notice of
availability of the draft  guideline docu-
ment and invite comments on  its con-
tents. After publication of a final guide-
line document for the pollutant  in ques-
tion, the States will have nine months
to develop and submit plans for control
of that pollutant from designated facili-
ties. Within  four-months after the date
for submission of plans, the Admmlstra-
          PROPOSED RULES

tor will approve or disapprove each plan
(or portions thereof). If a state plan (or
portion thereof) Is disapproved, the Ad-
ministrator will promulgate a plan  (or
portion thereof) within six months after
the date for plan submission. These and
related provisions of subpart B are basi-
cally patterned after section  110  of the
Act  and 40 CFR Part 51 (concerning
adoption and  submittal of state  imple-
mentation plans under section 110).
  As discussed in the preamble to sub-
part B, a distinction is drawn between
designated pollutants which may cause
.or contribute to endangerment of public
health  (referred to as "health-related
pollutants") and those for which adverse
effects on public health  have not been
demonstrated  (referred to as "welfare-
related pollutants"). For health-related
pollutants, emission standards and com-
pliance schedules in state plans must
ordinarily be at least as stringent as the
corresponding  emission guidelines  and
compliance times  specified  in  EPA's
guideline documents and codified in sub-
part C of 40 CFR Part 60. States may
apply less  stringent requirements when
economic factors or physical limitations
make such application significantly more
reasonable. For welfare-related pollut-
ants. States may balance the  emission
guidelines, compliance times, and other
Information in EPA's guideline docu-
ments against other factors  of  public
concern in developing their plans, as ex-
plained more  fully in the preamble  to
subpart B and in the introductory por-
tion of each guidelinefdpcument. Thus,
tfce States have'more flexibility in estab-
lishing plans for welfare-related pollut-
ants than for  plans involving pollutants
that may affect public health.     ''
  Standards of performance for sulfuric
acid mist  emissions  from new sulfuric
acid production units were promulgated
on December 23,  1971 (36 FR 24876). A
draft guideline document for the con-
trol of sulfuric acid mist emissions from
existing sulfuric  acid production units
has  been prepared and  Is available  as
specified below. In accordance with sec-
tion 117(f) of  the Act, publication of the
draft guideline document was preceded
by consultation with appropriate advi-
sory  committees,  independent experts,
and Federal departments and agencies.
A copy of the draft guideline document is
available for Inspection at the Public In-
formation  Reference Unit  (EPA  Li-
brary), Room 2922,  401 M Street, S.W.,
Washington, D.C. In addition, copies may
be obtained free of charge by writing to
the  Public Information  Center  (PM-
215), Environmental Protection Agency,
Washington, D.C. 20460  (specify: Draft
Guideline  Document: Control of Acid
Mist Emissions from Existing Sulfuric
Acid Production Units. September 1976).
  The  Administrator has determined
that sulfuric acid mist is a health-related
pollutant. The rationale for  this deter-
mination is included in Chapter 5 of the
draft guideline document. In summary,
sulfuric acid  mist has been shown  to
cause acute and chronic irritation to the
lungs  and bronchial tubes in humans.
Toxicological  studies have shown  that
 of all sulfates, sulfuric acid mist is the
 greatest respiratory irritant. There are
 human clinical studies  specific  to sul-
 terlc add mist which indicate health ef-
 fects occur In healthy, young adults with
 abort-term exposure to levels reasonably
 expected  to  occur around  uncontrolled
 aulfuric acid plants.  It  is a reasonable
 conclusion that potentially more sensi-
 tive individuals such as Infants, the el-
 derly, and persons whose health is al-
 ready  compromised  by  pre-existing
 health problems would  exhibit adverse
 effects at even lower levels than the clin- '
 teal studies  indicated, or more serious
 adverse effects at the levels studied.
   In addition to health effects, sulfuric
 acid mist has the following effects on
 public welfare as that term is defined in
 .the Act:  reduced  visibility; acceleration
 of metal corrosion;  disintegration  of
 building materials, especially those con-
 taining calcium carbonate;  textile and
 paper damage;  and vegetation damage.
   The emission guideline and time for
 compliance, in this proposed rulemaking
 reflect the Administrator's judgment on
 the degree of emission control achievable
 with the  best system of emission reduc-
 tion (considering the cost of such reduc-
 tion)  that has been adequately demon-
 strated for existing sulfuric acid produc-
 tion units and the time  within which
 those systems can be purchased and in-
 stalled. The proposed sulfurlc acid mist
 emission guideline of 0.25 gram acid mist
 per kilogram of acid produced (0.5 lb/
 ton) te based upon the degree of-control
 achievable  through the application of
 fiber mist eliminators to existing sulfuric
 acid production units. There are three
 types of fiber mist eliminators: vertical
 tube, vertical panel, and horizontal dual
 pad. The vertical panel and horizontal
 dual pad mist eliminators are less effec-
 tive and less expensive than the vertical
.tube  mist  eliminators.  The acid mist
 standard of performance for new sul-
 furic acid plants (0.075 g/kg) was based
 •on application of vertical tube mist elim-
 inators. The reason for the difference be-
 tween the emission  guideline  and the
 standard of performance for new sources
 Is the.consideration of cost. Sulfuric acid
 production units burning sulfur and pro-
 ducing, only acid  or low strength oleum
 are easily controlled to 0.25 g/kg using
 vertical panel  or horizontal  dual  pad
 mist eliminators. Plants 'burning bound
 sulfur feedstocks  and/or  producing
 strong oleum normally must use vertical
 tube mist, eliminators to attain .0,25. g.'
 kg  or less.  Compliance with  the new
 source standard requires installation of
 a vertical tube fiber  mist eliminator on
 all types  of plants. Many sulfur burning
 plants presently  have  horizontal dual
 pad or vertical panel type mist elimina-
 tors installed and thus, the double retro-
 fitting involved with a guideline less than
 0.25  g/kg would cause an  adverse eco-
 nomic impact on the industry.
   It is Important to note that the eco-
 nomic .analysis regarding double retro-
 fitting leading to the emission guideline
 was performed on a national scale. State
 standards as low as the standard of per-
 formance for new sources can be SUP-

STANDARDS OF PERFORMANCE FOR NEW
        STATIONARY  SOURCES
     Lignite-Fired Steam Generators
  The Environmental Protection Agency
(EPA)   is  considering amendments  to
Subpart D of 40  CFR Part 60  (Fossil
Fuel-Fired Steam Generators) to estab-
lish standards of performance for emis-
sions of nitrogen oxides from new lignite-
ftred steam generators of greater than 73
megawatts heat input (250 million Btu
per hour) and to incorporate the Inter-
national System of Units (modernized
metric system) , as applicable.
  On December 23, 1971  (36 FR 24877),
EPA promulgated standards of perform-
once for fossil  fuel -fired steam  genera-
tors. Included were standards for partic-
olate matter, sulfur  divide, and nitro-
gen oxides applicable to  gaseous, liquid,
and solid fossil fuel-fired facilities. How-
ever, because of a lack of information on
nitrogen oxides emissions, lignite-fired
facilities were exempted from the nitro-
gen oxides standard for solid fossil fuels,
although they are subject J*> the stand-
ards for particulate  matter  and sulfur
dioxide.                            __
  EPA has gathered additional informa-
tion on lignite-fired  facilities  and  the
background1 materials on the proposed
amendment to Subpart D have been pub-
lished  in a report entitled "Standards
Support  and  Environmental  Impact
Statement, Volume 1: Proposed Stand-
ards of  Performance for Lignite.-Fired
Steam Generators", hereafter referred to
as SSEIS. Copies are available on request
from the EPA Public Information Cen-
ter (PM-215), Environmental Protection
Agency, Washington, D.C. 20460 (specify:
Standards Support and  Environmental
Impact Statement, Volume  1: Proposed
Standards of Performance for Lignite-
Fired Steam Generators) . The informa-
tion contained in the SSEIS is briefly dis-
cussed in this preamble to Uie proposed
standard of performance.
    INTERNATIONAL SYSTEM OF UNITS

  In accordance with the objective to
implement national use of tSie metric
system, EPA presents numerical values in
both metric units and English units in
Its  regulations  and  technical  publica-
tions. In an effort to simplify use of the
metric units of measurement, EPA now
uses the International System  of Units
(SI) as set forth in a publication by the
American Society for  Testing and Mate-
rials entitled "Standard for Metric Prac-
tice"  (Designation: E 380-76). There-
fore,  EPA is proposing  to  revise  the
appropriate  sections  of  Subpart D to
reflect use of SI units.
           PROPOSED STANDARD

  The proposed standard of performance
limits  emissions  of nitrogen  oxides to
260 nanograms per joule of heat input
(0.6 pound per million Btu) from lignite -
fired steam generators having a capacity
 greater than 78 megawatts heat input
 rate (250 million Btu per hour). The pro-
 posed standard  reflects  the degree of
 emission  limitation achievable  through
 the application  of the  best system of
 emission  reduction which  (taking into
 account  the cost of achieving  such
-reduction) has been adequately demon-
 stratedy -The best-system is considered to
 be a combination of staged combustion
 and low excess air.
  ECONOMIC AND ENVIRONMENTAL IMPACTS
   Based on historical growth rates, it is
 estimated that 25 new lignite-fired steam
 generators would be subject to  the pro-
 posed standard  by 1985. The proposed
 standard would reduce NO, emissions by
 128,000 Mg/yr (141,000 T/yr).  Control-
 ling  NO. emissions to the level of the
 proposed standard would result in in-
 significant increases  in capital  and an-
 nualized  costs for the utility.
   Sinee approximately 90 percent of lig-
 jilte-fired steam generators of rated ca-
 pacity greater than  73 MW heat input
 are owned by electric utilities, the cost of
 complying with the  proposed standard
 was analyzed for the lignite utility indus-
 try. The cost to the utilities appears  to
 be negligible relative  to the capital in-
 vestment  costs. Available  information
 indicates that, at most, nitrogen oxides
 control  would increase capital invest-
 ment costs by only 0.5 percent for a new
 lignite-fired utility boiler and  ancillary
 equipment. This cost increase  for NO,
 control represents an  estimated increase
 of two dollars per installed kilowatt rela-
 tive to an estimated typical cost of about
 400  dollars  per installed  kilowatt ca-
 pacity based on costs for a bituminous
 coal-fired boiler island. The costs for NO,
 control would have negligible effect on
 power costs  to consumers. The review  of
 the economic impact has shown' that the
 proposal is not a major action under the
 Inflationary  Impact  Statement (US)
 program, and no IIS is needed.
   The environmental  impact of the pro-
 posed standard  is beneficial since the
 increase  in emissions due to growth  of
 lignite-fired steam generators would be
 minimized.   The  proposed  standard
 should result in a 20 percent reduction
 in the mass of nitrogen oxide emissions
 from new lignite-fired boilers.  It would
 reduce the atmospheric burden  of nitro-
 gen oxides and  would help prevent in-
 creased ambient oxidant concentrations
 in areas  where lignite-fired steam gen-
 erators will  be located (primarily North
 Dakota and  Texas).  There are no ad-
 verse environmental impacts associated
 with  the proposed  standard.  Control
 techniques required to comply  with the
 .proposed standard do not cause.boiler
 efficiency losses, and  thus there are no
 incremental energy demands associated
 with the proposed standard. A complete
 analysis  of the  economic and  environ-
 mental impacts may be found in Chap-
 ters  VI and vm of the SSEIS. '

           CONTROC SYSTEMS
   Nitrogen oxides from  fossil-fuel com-
 bustion are formed via two mechanisms:
 (1) Thermal fixation (oxidation) of at-
 mospheric nitrogen (Ns) in the combus-
 tion air, and  (2)  oxidation of organic
 nitrogen in the fuel. Oxidation of N, can
 be prevented  by reducing the level of
 thermal excitation in the flame by means
 of (a)  flue gas recirculation, (b) staged
 combustion, (c)  water injection, (d) re-
 duced  air preheat, or (e) combinations
 of  these  techniques.  Nitrogen  oxides
 emissions  due to  the oxidation of or-
 ganic nitrogen in the fuel can be con-
 trolled by using fuels with small amounts
 of organic nitrogen and by removing oxy-
 gen  from  the  volatilization  zone  by
 means of (a)  low excess air, (b) staged
 combustion, and/or (c)  fuel/air mixing
 pattern  adjustment  (burner  design).
 Fuels such as  coal, residual oil, and lig-
 nite contain 0.2 to 1.5  percent organic
 'nitrogen,  and oxidation  of  this  fuel-
 nitrogen may be responsible for as much
 as 80-90 percent  of the total nitrogen
 oxides emissions  from  pulverized  coal '
 combustion. Therefore, the organic nitro-
 gen  content of  fuel may be a limiting
 factor in  controlling  nitrogen oxides
 emissions. The fact that the organic ni-
 trogen content of the U.S. lignites does
 not vary appreciably precludes nitrogen
_ oxides control by switching  to lignite
 with a lower organic nitrogen content.
   Water injection and reduced air pre-
 heat significantly reduce the efficiency
 of a steam generator, and consequently
 are  not practical -nitrogen oxides con-
 trol methods. Flue gas recirculation does
 not  reduce nitrogen oxides  emissions
 caused by the oxidation of the organic
 nitrogen in the  lignite and it adversely
 affects  the  efficiency of a steam  gen-
 erator. Therefore, low excess air (LEA>,
 staged combustion (SC), low emission
 burners, and combined LEA and SC are
 considered the most feasible control sys-
 tems.
   In addition to the control systems just
 discussed, the fuel burning  equipment
 design parameters can affect the amount
 of nitrogen  oxides emitted and the de-
 gree to which the control systems are
 effective. Lignite-firing has been demon-
 strated in pulverized-fired, cyclone-fired,
 and stoker-fired steam generating units.
 Stoker-fired units have the lowest heat
 release rate and thus have lower nitro-
 gen oxides emissions than the other type
 units but are limited in physical size and
 are not expected to be of importance in
 future  lignite-fired  steam generating
 units. Cyclone-fired units have the high-
 est heat release rate and the highest ni-
 trogen oxides emissions. Pulverized-fired
 units have a lower heat release rate than
 cyclone-fired units, but  a higher release
 rate than stoker-fired units.

           EPA TEST PROCRAM
   Of the 15 lignite-fired units in domestic
 operation In 1974, four utility sized units
 were chosen for  EPA's test program. In-
 cluded were three pulverlzed--fired  units
 (two tangentiaUy-flred and one horizon-
 tally opposed-fired), and one cyclone-
 fired unit.
   Operating with low excess air and/or
 staged combustion, all types of fuel burn-
 Ing equipment exhibited reduced nitro-
 gen oxides emissions over baseline con-

         The Ikorlasifeany opposed- aad
 cyclone-fired unite are more responsive
 to nitrogen oxides scontrol tedinlques on
 a percentage basis, tort the tangentiany-
 fired  units  rcsing  staged   combustion
 yielded the lowest nitrogen oxides emis-
 sions. Cyclone-fired units cannot be de-
 pendably operated with low excess air
 firing or staged combustion because of
 flame  Instability  problems;  however,
 staged combustion of cyclone-fired units
,«an be achieved by firing auxiliary fuel.
   On  the baste of  the test data,  It sp-
 jpears  Siat fiie  cyclone-fired units can-
 not consistently meet a nitrogen  oxides
 standard more stringent than 340 nano-
 grams per joule (0.8 pound  per million
 Btu). The test data also indicate that
 horizontally opposed-fired units  would
 have difficulty consistently achieving a
 nitrogen  oxides standard of 260  nano-
 grams per Joule (0.6 pound million Btts)
 over Q long time period. However, de-
 velopment of tow emission burners ap-
 pears  promising for application to hori-
 zontally opposed-fired smite, and such
 units should be able to attain & standard
 of  260 nanograms  per  joule.  Tangen-
 tially-flred units should have no difficulty
 meeting -a standard of  §60  nanograms
 per jcrate,
   RATIONALE FOR PROPOSED STANDARDS
   In deciding the nitrogen oxides limit
 for the proposed standard, EPA consid-
 ered proposing  the same standard fo?
 lignite-fired  steam  generators as  the
 present  standard for coal-fired  steam
 generators,4 300 nanograms per joule 10.1
 pound per million Btu).  In the study on
 control of nitrogen oxides emissions from
 lignite-fired  steam  generators, staged
 combustion and low excess air were found
 to reduce emissions significantly  below
 300 nanograms per joule input (0.7 pound
 per  minion Btu). The measured  emis-
 sion levels of 172 to 320 nanograms per
 joule heat Input (0.4 to 0.5 pound per.
 million Btu) indicated that the present
 standard for coal-fired units would not
 require use of best demonstrated control
 technology, considering costs, for lignlte-
 flred units.  Studies  on control  of  nitro-
 gen oxides emissions by combustion mod-
 ification  techniques have  shown  emis-
 sion levels for modern bituminous  and
 subbitumlnous  coal-fired  utility   sized
 wilts to be similar to those observed for
 Jignite-flred  units. The  lower   emission
 levels  observed for the lignite and bitu-
 minous fired units  reflect an  improve-
 ment  in combustion modification tech-
 niques and  in the design of the burners
 and of boilers between 1970 and 1974.
   Tangentially-fired units  could  most
 likely meet a standard of 220 nanograms
 per  joule (0.5 pound per million Btu).
 This standard, however may not be xx>n-
 eistently achievable by the horizontally-
 opposed fired boilers. Since the manufac-
 turers of those  units do not make tan-
 sentially-fired boilers, a  standard  of 220
 nanograms per joule could leave only one
 manufacturer   of   complying  boilers,
 which would remove the option  of power
 companies  to  obtain competitive bids.
 SPA requests comments on  the follow-
 ing Issues: (1) ^SSneiiher horizontally-op-
 posed fired betters could meet a standard
 of 220 nanograms per joule; (2) if not,
 what would be the effect on the competi-
 tive balance of the equipment manufac-
 turing Industry;  (3) what would be the
 effects on the power Industry; and (4)
 whether EPA can consider these factors
 in setting standards based  on the best
 system of emission reduction which has
 been adequately demonstrated.
  The proposed standard of 260 nano-
 grams per joule  for lignite-fired steam
 generators is based on emission and cost
 data  currently available to the  Admin-
 istrator. The proposed standard, whfle
 numerically  more  stringent  than  the
 present  standard for coal-fired  units,
 will require lignite-fired units- to apply
 4fae same type of combustion modifica-
 tions as coal-fired units. EPA recognizes
 that  lignite-fired cyclone units cannot
 achieve €be proposed standard  of  260
 nanograms per joule (0.6 pound per mil-
 lion Btu) r therefore, EPA has considered
 the impact such  a standard would have
 on  bofler manufacturers  and on  fee
 lignite-fired steam generating industry.
 EPA determined that the impact on boil-
 er manufacturers of indirectly prohibit-
 ing cyclone-fired unite would be negli-
 gible. Only one boiler manufacturer mar-
 bets cyclone-fired units and that manu-
 facturer aJso markets pulverized-fired
 units. Effective prohibition of cyclone-
 ared units te expected to have little effect
 aa this manufacturer because these units
 represent a  minor percentage of the to-
 tal annual  sales  for the.manufacturer.
  The impact of the proposed standard
 on the lignite-fired steam generating in-
 dustry is not wen defined. EPA has at-
 tempted 60 determine  whether units
 other than cyclone-fired units are availo
 able that will meet  the proposed stand-
 ard and if any cost OF operating relia-
 bility advantages exist between these
 units and the cyclone-fired units.  For
 large lignite-fired steam  generators an
 alternative to cyclone-fired units is pul-
 verized-fired  unite.  From consultations
 with  the major  bofler manufacturers
 EPA  concluded that cyclone-fired units
 do not have any significant investment
 cost advantages over an equivalent pul-
 verized-flred unit. Thus,  the  impact of
 the prohibition of cyclone-fired units is
, dependent on the relative operational ad-.
 vantages of cyclone-fired units over pul-
 verized-fired units.
  Almost all  of  the large  lignite-fired
 units in North Dakota have experienced
 severe operational difficulties as a result
 of ash fouling of the boiler tube surfaces.
 Utility boilers firing Texas lignites have
 not experienced ash fouling problems to
 the same degree.  Research conducted by
 the Energy Research and Development
 Administration (ERDA) in Grand Forks,
 North  Dakota,  has  shown  that  the
 sodium content of the lignite is highly
 correlated with the degree of ash fouling.
 Lignite ash with three to  five  percent
 sodium is considered to have a moderate
 to high fouling potential, and a sodium
 content greater than five percent has  a
 severe fouling potential. In EPA's judg-
 ment, the ash fouling problem can be
 minimized by designing the bofler with
 more .soot  blowers  in  the convective
       than normal, with larger spacing
between bofler tubes, and with design of
•Hie furnace temperature profile to con-
trol tube metal.temperatures.
  Some  of the  lignite utilities  have
claimed- that cyclone-fired  units  can
burn  lignites  with the higher sodium
content more reliably than pulverized-
flred units because a smaller proportion
of the ash enters the boiler. The utilities
cited  the Minnkota Power  Cooperative's
cyclone-fired unit  at Young-Center sta-
tion as a successful example.  This  cy-
clone-fired, 235 MW boiler was selected
and designed based  on a cooperative
study   to develop a better method for
firing high sodium lignite.  The unit has
an excellent record of operating availa-
bility since its startup to 1970.  However,
the unit has not fired the high sodium
lignites for which it was designed. In ad-
dition, the  operating reliability of this
unit may be attributed to furnace de-
sign  features other  than the cyclone
burner. Since startup of the Minnkota
cyclone-fired unit, two additional  cy-
clone-fired  units  have been placed  in
commercial operation by  power  com-
panies and cooperatives in the area. Each
of these units has been in  operation for
less thaa a year. Both units have  been
firing  lignites of approximately 4  to 6
percent sodium and have been experienc-
ing problems  with ash fouling of  the
boiler tubes and with furnace slagging to
different degrees. Since numerous oper-
ating problems typically occur in the first
year of operation  of a steam generator.
more operating experience  is needed be-
fore the performance and reliability of
these  units on  high sodium   lignite is
evaluated.
  Experience with pulverized-fired units
is presently limited to two units designed
to the early 1960's. At that lime  prob-
lems with plugging in the convective pas-
sages because of  ash fouling associated
with firing high sodium lignite were noi
fully  appreciated.  Consequently,  these
two units  were retrofitted with an in-
creased number of sootblowers and the
tube spacings were increased in order to
obtain  reliable operation  of the  units.
Redesign  of  this nature  was  imple-
mented to different degrees on the units.
The more extensively retrofitted unit hr>5
operated reliably for six years on lignite
with  four to six percent sodium in the
ash and on eight to nine percent sodium
lignite for the past year. The less exten-
sively retrofitted unit can be reliably op-
erated by maintaining the sodium  con-
tent of the fuel below five percent. Base^
on this experience, new cyclone or pul-
verized lignite-fired units  are  designed
with  greater furnace  surface  area, in-
creased  superheater  tube  spacing, and
increased number  of  sootblowers.  This
early experience  with pulverized  firing
apparently  has not convinced  the util-
ities that pulverized firing of high sodium
lignite is impractical.  In the early 1970's.
the  United Power Association  (UPA>
purchased   two  pulverized-fired   units.
after  evaluating bids on both cyclone and
pulverized-fired  units. These  tangen-
tlally-flred  500 MW boflers were  guar-
anteed to reliably Ore & lignite with a de-
sign range of 0.1 to 4.8 ps?eent sodium.

-------
 This selection of a pulverized-fired unit
 for  a North Dakota lignite with high
 fouling potential indicates that pulver-
 ized-fired units are price  competitive
 with cyclone-fired units and that at least
 one  utility  believes that  cyclone-fired
 units are not required for use of a lignite
 with high fouling potential
   In addition to this limited experience
 with firing'high sodium lignite, prellmi-
• nary results from  a  study conducted by
 ERDA  showed that  cyclone-fired units
 have a statistically significant lower ash
 deposition  rate  than  pulverized-fired
 units. The test was conducted while the
 units were firing 3.5 to 4.5 percent sodium
 lignite  and  insufficient  information Is
 available to  allow  comparison at higher
 sodium levels. One possible  Interpreta-
 tion  of these data is that cyclone-fired
 units can operate on high sodium lignite
 (greater than six percent) more reliably
 than pulverized-fired units. However, the
 study's results are not consistent with
 the  experience of  operating commercial
 units and the data may not warrant
 drawing this conclusion.
   EPA has  concluded from evaluation
 of the available Information  that  (1)
 while there are differences in operational
 characteristics of pulverized  and  cy-
 clone-fired units, both types can reliably
 operate on high sodium  lignite and (2)
 cyclone-fired units do not have signifi-
 cant operation maintenance, or cost ad-
 vantages over pulverized-fired units. The
 manufacturers of  pulverized-fired units
 believe that  these  units can be as effec-
 tive  as cyclone-fired units for burning
 lignites,  including those with  high so-
 dium. Combustion Engineering, which is
 Installing the units'f or UP A, is  confident
 that pulverized-fired units can be prop-
 erly  designed  to handle  the ash fouling
 and  slagging  problems of high sodium
 lignite. Babcock and Wilcox, the other
 major supplier of lignite-fired  units,  al-
 so believes that a pulverized-fired unit
 can  be  designed to reliably burn  high
 sodium lignite. Due to the limited Infor-
 mation available at this time and differ-
 ent possible  Interpretations  of the  In-
 formation, EPA realizes that the assess-
 ment of relative reliability of pulverized
 and  cyclone-fired  units  for  firing  high
 sodium  lignite Is  debatable. Therefore,
 EPA is requesting that all interested per-
 sons submit factual  Information on  this
 issue during the comment period. Fac-
 tual information Is specifically  requested
 on the following areas of Interest:
   1. Investment costs and operation and
 maintenance costs for either pulverized-
 fired or cyclone-fired large steam genera-
 tors  designed for  moderate  or  high
 eodiiun lignite.
   2. The differences, if any, in the design
 of the convection section or the.gas tem-
 perature profile between cyclone  and
 pulverized-fuel fired steam  generators.
 The comparison should discuss any  dif-
 ferences  in the number, type or location
 of soo'tblowers  installed, frequency of
 operation of soot blowers, comparison of
 tube spacings or depth of tube banks and
 other relevant factors.
   3.  Relative importance of factors con-
 sidered In selecting a cyclone- or pul-
 verized-fired unit.
                      MtOPOSED MILES

            , It is expected that the above Informa-
           tion win allow EPA an opportunity to
           assess the relative costs of cyclone and
           pulverized fuel fired lignite steam gen-
           erators as well as to assess the need for
           cyclone-fired  units  for  use of  high
           sodium lignite. The final  standard will
           reflect the conclusions drawn from eval-
           uation of all available factual informa-
           tion. EPA will limit the scope of coverage
           of the final standard  if the data sub-
           mitted during the comment period jus-
           tify such a change. The scope of coverage
           could be limited by applying the stand-
           ard to lignites having a specified sodium
           content,  by  establishing a separate
           standard for cyclone-fired units, or ex-
           empting cyclone-fired  units.
             It should  be noted  that standards of
           performance for new sources established
           under section  111 of the Clean Air Act
           reflect emission limits achievable with
           the  best  adequately demonstrated sys-
           tems of emission reduction considering
           the  cost of  such systems.  State imple-
           mentation  plans (SIP's)   approved or
           promulgated under section 110 of the
           Act, on the other hand, must provide for
           the attainment and maintenance of na-
           tional ambient air quality standards
           (NAAQS)   designed  to protect public
           health  and welfare. For  that purpose
           SIP's must in some cases require greater
           emission reductions than those required
           by standards  of performance for new
           sources.  In addition, States are free un-
           der  section  116 of the Act to establish
           more  stringent  emission  limits  than
           those  established under section 111 or
           those necessary to attain or maintain the
           NAAQS  under section 110.  Thus, new
           and existing sources may  in  some  cases
           *e subject to limitations more stringent
           than EPA's standards of performance
           under section 111.

  STANDARDS OF PERFORMANCE FOR
      NEW STATIONARY SOURCES
Petroleum Refinery Fluid  Catalytic Cracking
        Unit Catalyst Regenerators

  Under the authority  of section 111 of
the Clean Air Act, as amended, the Ad-
ministrator is proposing a revision to 40
CFR  60.102(a)(2),  and  60.105(e) (1),
opacity standard of performance for new,
modified, and  reconstructed  petroleum
refinery  fluid  catalytic  cracking, unit
catalyst regenerators.

          PROPOSED REVISION

  The proposed  revision would  change
the opacity standard from 30  percent,
except for three minutes in any one hour,
to 25  percent, except for two six-minute
average opacity readings in any one hour.
The revised standard would be  neither
more  nor less stringent  than the  present
standard, but would be consistent with
the new provisions for determining the
opacity of emissions.
              RATIONALE

  On June 29, 1973,  the VJ5. Court of
Appeals for the District of Columbia cir-
cuit remanded to EPA the new source
performance standard  for Portland ce-
ment plants (40 CFR 60.62) promulgated
under section 111 of  the Clean Air Act
(.Portland Cement Association v. RucJeels-
haus, 486 F. 2d 375). One of the Issues
remanded was the use of opacity stand-
ards.  On November 12,  1974, EPA re-
sponded to the remand (39 PR  39872) ;
and on May 22, 1975, the Court affirmed
the use of opacity standards  (513 F. 2d
506).
  In the response, EPA reconsidered the
use of opacity standards and concluded
that they are a reliable, inexpensive, and
useful means of ensuring that  control
equipment is properly  maintained and
operated at  all times.  EPA also made
changes  to the general provisions of 40
CFR Part 60 and to the test method for
determining the opacity of emissions to
eliminate the possibility of  a properly
maintained and  operated source being
In violation  of the applicable  opacity
standard while concurrently meeting a
mass or concentration emission standard
applicable to the source.
  The principal revisions to the  regula-
tions  (40 CFR Part 60, Standards of Per-
formance for New Stationary Sources)
which apply to all opacity standards are
as follows:
  1. Reference Method 9 (the  opacity test
method)  was revised to base compliance on
the average of 34  consecutive opacity, ob-
servations, each taken at 15-second Intervals
(six-minute average), and  to define the marl-
mum error associated with each set of opac-
ity observtalons. The revision changing the
averaging time to six minutes was Included
to require sufficient observation  to ensure
acceptable accuracy within the maximum
average error referenced In Method 9. The usa
of sets of opacity data srlll preclude a single
high reading £ram  being cited cs a violation.
  2. Section 60.11(e) was added to provide
s generally applicable  mechanism  for any
owneo or operator to petition the Adminis-
trator to obtain a higher opacity standard
for  any facility that demonstrates  compli-
ance with the mass or concentration emission
standard concurrent with failure to comply
with the opacity  standard.  This provision
provides relief to those source owners and
operators who install unusually large diam-
eter stacks or  whose emissions have  unusual
characteristics which could cause the opacity
of the emissions to be greater than is typical
for  other plants In the same source category.
The provision allows the promulgated opacity
standards to be based on the maximum ef-
fects of  particle characteristics and  stack
diameters  at  well-controlled  new  installa-
tions, and ensures that no owner or  operator
of an affected facility  will be prejudiced l£~
the facility is not able to meet  the opacity
standard while meeting the mass or concen-
tration emission standard.

  As a result of the revisions  to  Method
9,  EPA has reevaluated  the  opacity
standard for fluid catalytic cracking unit.
catalyst regenerators and concluded that
it should be revised. This proposed revi-
sion of the opacity standard is consistent
with the particulate emission standard
for fluid catalytic cracking unit  catalyst
regenerators of  1.0  kilogram per  1000
kilograms of  coke burn-off in the  catalyst
regenerator.
  The proposed revision of the  opacity
standard is based primarily upon a re-
evaluation of the data gathered on facil-
ity  A of the  background document  sup-
portjng  promulgation of  the  opacity
standard  (Background Information for

ary  1973). Six-minute average  opacity
readings calculated from these data in-
dicated that opacity seldom exceeded 20
percent, except during periods  of soot
blowing. Emission  testing clearly  indl-r
cated that this facility was meeting the
particulate emission standard at the time
these, opacity data were gathered.
  Three different emission control sys-
tems can be installed to comply with the
particulate and carbon monoxide stand-
ards of performance. These systems are
shown In Figure  1. The volume of  gases
discharged  from control system  3  is
about 30 percent greater than the volume
of gases discharged from either-control
system 1 or 2. Consequently, the opacity
of the  gases  discharged from system 3
is lower than that of the gases discharged
from the other two systems. Faculty A
employed emission control system 3.
  The  opacity observed  at facility A,
therefore, is somewhat lower than that
which  would be observed at facilities
which employed  either emission control
system 1 or 2. Extrapolating the opacity
data from facility A using Bouger's Law
indicates that the opacity at facilities us-
ing either of these other two emission
control systems would not exceed 25 per-
cent. Thus,  the revised opacity standard
is proposed at 25  percent.

   Another factor which Influences opac-
 ity,  but not particulate emissions  (In
 terms of the emission standard), is s tacts

 of a fluid  catalytic cracking unit, the
 larger the stack diameter. Facility A la
 about 50,000 barrels per day. Although
 the size of fluid catalytic cracking units
 may  vary  from 5,000 to 95,000 barrels
 per day, the typical facility within the
 petroleum  refining Industry is  in the
 range of 25,000 to 50,000 barrels per day.
 The Influence of this wide range In tha
 size of  fluid catalytic cracking units on
 opacity of the gases discharged from the
 catalyst regenerator can be calculated
 using Bouguer's  Law. With particulate
emissions of 1.0 kilogram per 1000 kilo-
grams of coke bum-off, the opacity varies
from as little as 10 percent for the small-
est units (5,000 barrels per day) to as
much  as 40 percent for the largest units
(95,000 barrels per day).
  New fluid  catalytic  cracking units,
however, are expected to be in the range
of 25,000 to 50,000 barrels per day. Cur-
rently, there is only one 95,000 barrels-
per-day unit, and only a few larger than
50,000 barrels per day. The proposed re-
vision  of the opacity standard, therefore,
Is based on the largest new fluid, catalytic
cracking unit that is likely to  be built
(ie. 50,000 barrels per day).  If  fluid

                                                 PROPOSED RULES
50,000 barrels per .day are built, or exist-
ing units are modified or reconstructed,
and these facilities have trouble meeting
the proposed revised opacity standard,
relief  can  be  obtained through  the
mechanism  of §60.11(e).
  At most fluid catalytic cracking units,
carbon  monoxide emissions  are con-
trolled by carbon monoxide boilers. Pe-
riodically, the boiler  tubes require soot
blowing to remove dust or soot deposited
on  these tubes.  Soot blowing increases
the opacity of the plume from the cata-
lyst regenerator dramatically, although
only momentarily. Rather than increase
the level of  the  opacity standard to in-
clude soot blowing, therefore, it is more
appropriate  to  provide  an  exemption
from the standard. The opacity data in-
dicate that  an  exemption of  two six-
minute  average  opacity readings per
hour is necessary to permit soot blowing.
Thus, an exemption  for  soot blowing is
included in  the proposed revision to the
opacity standard.
  It should  be noted that standards of
performance for new sources established
under section 111 of  the Clean Air Act
reflect emission limits achievable with
the best adequately  demonstrated sys-
tems  of  emission reduction considering
the cost of such system. State implemen-
tation plans (SIP's)  approved or  pro-
mulgated under section  110 of the Act,
on the other hand, must provide for the
attainment and maintenance of national
ambient  air  quality standards (NAAQS)
designed to protect  public  health and
welfare. For that purpose SIP's mustJri
some cases require greater emission're-:
ductions than those  required by  stand-
ards of performance  for new sources. In
addition, States are  free under section
116 of the Act to establish  more strin-
gent emission limits  than  those  estab-
lished under section 111 or thos neces-
sary to attain  or maintain the NAAQS
under section 110. Thus, new and exist-
ing sources may in some cases be subject
to limitations more stringent than EPA's
standards of performance under'section
111.

  STANDARDS OF  PERFORMANCE FOR
      WEW STATIONARY  SOURCES
Irtetroteum Refinery Sulfur Recovery Plants
  Notice Is hereby given that under the
authority of section 111 of the dean Air
Act, as amended, the Administrator is
•proposing standards of performance for
new, modified or reconstructed petroleum
ffeflnery sulfur recovery plants.
  The Administrator is also proposing a
asw reference method  to be used for de-
termining emissions of hydrogen sulfide
rund reduced sulfur compounds from pe-
troleum refinery sulfur recovery plants.

          PBOPOSED STANDARDS

  As proposed, the standards would ap-
piy to petroluem refinery sulfur recovery
plants. Generally,  these plants are phys-
ically located within petroleum refineries.
Occasionally,  however,  refineries   will
pipe the sulfur-rich gas stream to a near-
by  facility,  such  as a chemical plant,
where the sulfur is recovered. The stand-
ards would apply to all refinery sulfur
recovery plants, whether they are pnysi-
cally located within a petroleum refinery,
or within the confines of another facility.
  The standards would limit the concen-
tration of sufur  dioxide (SO,) in the
gases discharged  to the atmosphere to
0.025 percent by volume at  zero percent
oxygen and on  a  dry  basis. Where the
emission control system Installed to com-
ply with these standards discharges re-
sidual  emissions  of  hydrogen sulfide
(as), carbonyl sulfide (COS), and car-
bon disulflde (CS.), the standards would
limit the concentration of H>S and the
total concentration of H.-S, COS  and CS,
(calculated as SO,) In  the gases  dis-
charged  to  the atmosphere, to 0.0010
psrcent and 0.030 percent by volume at
aero percent oxygen and on a dry basis,
respectively.  >
  ENVIRONMENT AND ECONOMIC IMPACTS

  The proposed  standards would require
new, modified or  reconstructed  refinery
sulfur  recovery  plants to reduce emis-
sions  by about 99 percent compared to'
Emissions from  existing refinery sulfur
recovery plants. This would Increase the
overall sulfur recovery of & typical re-
finery sulfur recovery  plant from about
94 percent to about 90.9 percent
  It is expected that the proposed stand-
ards would  apply to about 80 new re-
finery sulfur  plants by 1980. Fety, ff aay,
modifications or reconstructions of exist-
ing refinery sulfur plants are anticipated.
The proposed  standards would reduce
national sulfur dioxide  emissions from
gfcese new refinery sulfur plants by about
55,000 tons per year.
  This reduction  in national SO,  emis-
sions would be obtained without adverse
impacts on other aspects of the environ-
ment,  seen aa increased solid waste dis-
posal, tmte? pcQutteo,  cr noise. The pro-
posed  standards x/oald also result ia a
reduction in the growth of national en-
ergy consumption by some 54 million kw-
hr/yr, cr about 90,000 barrels of fuel oil
per year, by 1980.
  The economic Impact of  the proposed
standards would  be reasonable both on
large and on small refiners, although It
is somewhat more severe on small  re-
finers than large refiners. For the small
refiner [processing less than 30,000 bar-
rels per calendar day (BCD) ],  the pro-
posed standards could reduce profitabil-
ity, as measured by return  on assets, by
1.5 to 7.5 percent. A price increase of only
0.25 to 1.0 percent on all petroleum prod-
ucts, however,  would restore the small
refiner's  profitability. The  Impact on a
large refiner (processing more than 30,-
000  BCD)  is considerably less due  to
economies of scale. The proposed stand-
ards could reduce the profitability of a
large refiner by 0.5 to 1.5 percent. A price
increase  of only 0.10 to 0.30 percent on
all petroleum products, however, would
restore the large refiner's profitability.
Consequently, the proposed standards
would not adversely affect the growth of
either the large refinery or the small re-
finer sector of the  domestic refining in-
dustry,            f
  To comply with these proposed stand-
ards, the Investment  required  by the
domestic refining industry would total
some $110 million  (MM) over the five-
year period from 1976 to 1980;  the an-
nual operating costs  of  title  Industry
would increase by some $16 MM per year
by 1980  and  petroleum product prices
could increase  by 0.1 to 1.0 percent.
  The review of the economic impact has
shown that the proposal is not a major
action under the  Inflationary  Impact
Statement (IIS)  program and no ns is
needed.
  SELECTION op SOURCE CATEGORY AND
         •AFFECTED FACILITIES
  Section 111 of the Clean Air Act di-
rects tile  Administrator  to (establish
standards of performance  for new sta-
tionary sources of air pollution which
may contribute significantly to  air pol-
lution which causes or contributes to the
endangerment  of public health or wel-
fare. Sulfur recovery plants are  a major
source of SO, emissions in petroleum re-
fineries.  Although  a few State  or local
regulations  already  require  emission
control equivalent to the proposed stand-
ards, most State  regulations require less
stringent control  of refinery sulfur re-
covery plants.
  Reducing SO,  emissions from new,
modified or reconstructed refinery sulfur
recovery plants takes on importance In
view of the expected growth in the num-
bers and sizes of these plants,  and  the
urban location of  many petroleum  re-
fineries where high ambient air concen-
trations  of SO,  already exist  Current
growth  projections for  the  domestic
petroleum refining Industry, for example.
Indicate that  refinery suite  recovery
plant capacity will double  between 1970
and 1980.
   Considering  these  factors, the pro-
posed standards have bsEa developed to
KmK emissions of SO, from petroleum
 refinery sulfur recovery plants. Some of
 the emission control systems that might
 be installed to reduce emissions  of SO*
 however, discharge residual emissions of
 iiydrogen sulfide (HtS), carbonyl sulfide
 (COS) and carbon disulfide (CS,) to the
 atmosphere.   The  proposed  standards,
 therefore, include limits on emissions of '
 these pollutants.
               RATIONALE
 ~ Two alternative systems of SOa emis-
 sion  control were considered as candiates
 to serve as  the basis  for standards of
 performance:  (1)  the low-temperature
 extended  Claus reaction system  (alter-
 native I) and (2) various  tail gas scrub-
 bing systems (alternative n>. The alter-
 native I systems reduce emisssion from
 uncontrolled refinery sulfur recovery
 plants by 80-85 percent, while the alter-
 native n systems reduce emissions by 98-
 99 percent. Overall sulfur recovery of the
 refinery sulfur plant is increased from
 95 to 99.9 percent with the use of an al-
• ternative n system.
   Standards of performance based on al-
 ternative  I  would have  an  essentially
 negligible impact on  SOa emissions since
 most state implementation plans (SIP's)
. already require equivalent control. As
 outlined above, however, standards based
 on alternative n would reduce SOa emis-
 sions by about 90 percent below levels
 required by most SIP's and would lead to
 a reduction In national SOj emissions of
 some 55,000 tons per year in 1980. Stand-
 ards based on alternative n would also
 have no adverse environmental  Impacts
 in other areas such  as increased water
 pollution, solid waste disposal,  energy
 consumption, or noise. In addition, the
 economic  impact of standards based on
 alternative n would  be reasonable both
 on large and on small refiners. Conse-
 quently, alternative n represents the
 best  system  of emission  reduction and
 the proposed standards are based on this
 alternative.
   The tafl gas scrubbing systems of al-
 ternative n, however, Include two differ-
 ent types of  emission control systems for
 reducing SO» emissions from refinery sul-
 tur  recovery plants: oxidation  control
 systems and reduction control systems.
 In the oxidation control system,  the SO«
 emissions from a refinery sulfur plant are
 controlled directly by tafl  gas scrubbing.
 In the reduction control system,  the SO°
 emissions are first converted to H«S emis-
 sions which are then controlled by tafl
 gtta  scrubbing.  Residual  emissions  dis-
 charged into the atmosphere from oxida-
 tion  control  systems or from reduction
 control systems which are followed by
 Incineration  consist  of   SO». Residual
 emissions discharged  from  reduction
 control systems which are not followed
 by incineration, however,  consist.of H*S,
 COS (carbonyl sulflde) and CS>  (carbon
 disulflde). Standards limiting emissions
 of SO», therefore,  while appropriate for
 oxidation control  systems or reduction
 control systems followed by incineration,
 are not appropriate for reduction control
 systems not followed by incineration.

        are not  followed by Incineration

can  be present  to the feafl  gases  dis-
charged to the atmosphere. Where this
approach has been follower-emissions of
as are Ulmted to  10 ppm and emissions
of reduced sulfur compounds" are limited
to ettber 300 or 500 ppm.
  Where  emissions  of  reduced  suSfur
compounds are limited indirectly by local
regulations, 'Qiese  regulations  require
that the best available emission-control
technology be Installed. In the process
of specifying the best emission control
technology,  local  air pollution control
agencies have contacted EPA, vendors of
various emission  control  system,  and
other local air pollution control agencies
where these emission control systems
have been installed. In terms of limiting
emissions  of reduced sulfur compounds,
this approach has achieved the same end
result «s the direct regulatory approach.
AH 25 reduction control system which are
now  operating have been designed and
guaranteed by Qie vendors of these sys-
tems  to limit emissions to less than 10
ppm HsS  end less than 300 or 500 ppm
reduced sulfur compounds.
  Consequently, the current 25 petroleum
refinery sulfur plants which have  in-
stalled reduction control systems which
are not followed by incineration are not
considered  by  EPA  to  be  significant
sources of reduced sulfur compound emis-
sions. Developing State plans under sec-
tion lll(d)  to control emissions of these
pollutants from these faculties,, there-
fore, would not reduce existing emission
levels.
   On the other hand, Sf EPA were to pro-
pose standards of performance for refin-
ery sulfur plants  only for SO, without
limiting emissions of reduced sulfur com-
pounds, this action could be interpreted
to mean that EPA does not consider the
potential  air pollution problem posed by
emissions of reduced sulfur compounds
to be Important Such an interpretation
could encourage new plants  to be buOt
without Hmltlng emissions of these pol-
lutants.
   Having determined that the proposed
regulation should cover emissions of re-
duced sulfur compounds from new refin-
ery sulfur recovery  plants, but not ex-
isting ones. KPA Is left with th« problem
of selecting the appropriate pollutants to
control with the  proposed   standards.
Limiting   for
new sources will cause some expenditure
of effort on the part of EPA and the af-
fected States which is not in fact neces-
sary to achieve control of existing plants.
   Considering all  the facets of this  sit-
uation, EPA proposes to limit emissions
of both SOi and reduced sulfur com-
pounds by Qiese standards of perform-
ance, fulfilling the intent of section 111
of the Act to prevent new air pollution
problems  by requiring new, modified, or
reconstructed plants to tastall the bssfe
.systems of onisston reduction consider-
Sag costs. However, EPA Jo sonsldering
two alternative routes for Seating the
problem  of existing sources. One alter-
native is for EPA to Issue a guideline
document under  40 CFR  60.22 (based
primarily on the information available
in  the  support  documents  for  these
standards of performance) and to re-
quire the seven affected States to submit
plans under 40 CFR 60.23.  Those States
£hat  already  regulate  reduced  sulfur
compounds by State law will be able  to
submit relatively simple control plans.
Those States in which regulation of re-
duced sulfur compounds  has been ac-
complished ~by  local  ordinances  may
have  to  provide for State enforcement
before their  control plans can be ap-
proved.
  If the first  alternative appears  to  be
excessively burdensome, EPA Is also con-
sidering  a second  alternative, because
the 25 mrteMng sources are well con-
trolled. The purpose of limiting pollut-
ant emissions from existing sources un-
der the  provisions of section lll(d)  ts
to control a pollutant which may  cause
or contribute to the endangerment  of
public nealth or welfare, but'is not
known to be '"hazardous" jyithin the
meaning of section 112, and is not con-
trolled under  sections  IDS through 110.
Since action  Hinder section lll(d)  in
Mils instance would not further control
Q*e pollutant in  question, and existing
refinery  sulfur plants uhtch have  in-
stalled reduction control systems not fol-
lowed by incineration are not endanger-
ing the public health or welfare, the con-
clusion can be drawn that there is  no
purpose  to limiting emissions of  these
pollutants under section ill(d). Under
this alternative, EPA would not issue a
guideline document, the chain of events
requiring States to develop  plans  for
controlling emissions of these pollutants
would not be initiated and these plans
would not be developed. (A detailed dis-
cussion of this alternative may be  found
in the Standards Support  and Environ-
mental Impact Statement for Petroleum
Sulfur Recovery Plants.)
 • The data and information available  for
selecting specific emission  limits include
the results of emission tests both by the
Agency and by (local ah- pollution control
agencies, discussions with owners and
werators which have  installed and are
&Hm operating either the oxidation con-
trol systems or the reduction control sys-
tems, and discussions with the vendors of
•fl»ese emission control systems. The SO.
emission limit is based on  emission tests
at a  refinery  sulfur plant controlled  by
on -oxidation  control system and at a
refinery  sulfur plant controlled by a  re-
duction  control  system followed by in-
cineration. The HJ3 and reduced  sulfur
compound emission limits are based  on
emission source tests at  three  refinery
sulfur plants controlled by reduction con-
trol systems not foDowed by incineration.

experience of owners and operators with
'these emission control systems.
  The 0.025 percent by volume limit for
SOi emissions and the 0.030 percent by
volume limit  for  reduced sulfur com-
pound emissions are  also equivalent, in
the sense that both require achieving the
same degree of overall  sulfur recovery-
(Le., 99.9 percent). The  numerical limit
on BO: emissions is lower due to the some-
what greater volume of gases-discharged
from oxidation control systems and re-
duction control systems  followed by in-
cineration, which  is  inherent in their
•design and operation.
  It should be noted that standards of
performance for new sources established
under section 111 of  the Clean Air  Act
reflect  emission limits  achievable with
the best adequately demonstrated system
of  emission reduction  considering  the
cost of  such systems. State implementa-
tion plans  (SIP's)  approved or promul-
gated under section 110 of the Act, on the
other hand, must provide for the attain-
ment and maintenance of national am-
bient air quality standards CNAAQS*  de-
signed to protect public health and wel-
fare. For that purpose SIP's must in some
cases require greater emission reductions
than those required by standards of per-
formance for new sources. Indeed, build -
Ing of new sources may be precluded al-
together in some geographical areas, in
addition, States are  free under section
116 of the Act to establish more stringent
emission limits than those established
under section  111 or  those necessary to
attain or maintain the NAAQ under sec-
tion 110. Thus, new sources may in some
cases be  subject  to  limitations  more
stringent than EPA's standards of per-
formance under section 111,  and pro-
spective owners and  operators  of  new
sources should be aware of this possibil-
ity  in planning for such facilities.
               ENERGY

  The impact of the proposed standards
on the energy consumption of a refinery
sulfur recovery plant  varies depending
on  the  type of emission control system
Installed to comply with the standards.
If an oxidation control system or a  re-
duction control system followed with
incineration  were  used,  the  overall
energy  consumption of a typical sulfur
recovery plant would be increased by
some 30 percent. If a reduction control
system not followed by incineration were
used, however, the overall energy con-
sumption would be reduced by some 50
percent. These  percentages  are high
primarily because refinery sulfur recov-
ery plants  consume little energy. Typi-
cally, for example, a refinery sulfur re-
covery plant accounts for less than 1 per-
eent of  the total energy consumed within
a petroleum refinery.
  Assuming half  of the refinery sulfur
recovery plants affected by the proposed
standards by 1980 Install oxidation con-
trol systems or reduction control systems
followed by incineration and half install
reduction control ^systems  not followed
by  incineration, ;flie,'proposed standards
would reduce national aiergy consump-
tion in 1080 by some 54 million fcw-hr/yr,
or about;  90,000 barrels of fuel oil per.
year.                  .
      MOOTTORIKG, TESTING,  AND
          _ RECOUDKEEPING

  As proposed, the regulations would re-
quire monitoring of emissions released to
the atmosphere to insure that the emis-
sion control systems installed to comply
with the proposed standards are properly
maintained and operated. If an oxida-
tion control system or a reduction con-
trol system followed by incineration were
installed,  monitoring of SO, emissions
would be required and if a reduction
control  system not followed by incinera-
tion were installed,  monitoring of  H.S
and reduced sulfur compound emissions
would be required.
  Emission monitoring systems  for SO:
are readily available and performance
specifications for  these monitors have
already been promulgated by EPA in 40
CFR Part 60 Appendix B. Although a few
emission monitoring systems for HLS and
reduced sulfur compounds are available,
EPA has not yet developed performance
specifications for these monitors. Conse-
quently, until EPA  proposes and pro-
mulgates  these performance specifica-
tions, owners and operators subject to the
requirement to install H=S and reduced
sulfur compound emission monitors will
not be  required to do so. The  require-
ment  to install these monitors is included
in the proposed regulations; however, to
ensure that when EPA promulgates these
performance specifications, those owners
and operators who have installed reduc-
tion control systems  not followed by in-
cineration which are subject to  the pro-
posed standards will be required to retro-
fit these monitors. This will  enable en-
forcement personnel to ensure that these
emission control systems are being prop-
erly operated and maintained.
  The reference method for determining
compliance also depends on the emis-
sion control system employed to comply
with the proposed standards. If an oxi-
dation  control system  or  a reduction
control  system followed by incineration
were installed, Method 6—Determination
of Sulfur Dioxide Emissions  from' Sta-
tionary  Sources would be-used to deter-
mine  emissions of SOi. If a reduction
control  system not followed by incinera-
tion were installed, the proposed Refer-
ence Method 15—Determination of  Hy-
drogen Sulfide and Reduced Sulfur Com-
pound Emissions  from Sulfur Recovery
Plants would be used to determine emis-
sions  of HsS and total emissions of H:S,
COiS,  and CS, (calculated as SO:).
  The proposed Reference Method 15 is
based on  gas  chromatographic  separa-
tion followed by flame photometric de-
tection. This method permits separation
and identification of each individual pol-
lutant (i.e., H2S, COS and CSj). To de-
termine compliance  with the proposed
standards, a sample of the  gases  dis-
charged to the atmosphere is analyzed
to determine emissions of H«S, COS and
CS>. The concentration of H,S  in these
gases  is determined  directly. The con-
centration of reduced sulfur compounds
in these gases Js determined indirectly,
by adding together the concentrations of
HsS, COS and CSo. Since emissions are
calculated as SO., however, the concen-
trations of CSi (having twice the sulfur
per molecule  of gas)  is  multiplied by
two before adding it to the concentra-
tions of H,S and COS.
 AMENDMENT OF SUBPART  J OF PART 60
  The proposed standards would be  in-
corporated  into  40 CFR Part  60  by
amending  Subpart  J—Standards   of
Performance for Petroleum  Refineries.
Maintaining clarity within Subpart  J
while incorporating the proposed stand-
ards requires  amendment of a  number
of existing  paragraphs. In  all  but the
case discussed  below, these paragraphs
have  merely  been  rewritten with  no
change in content or intent.
  Recently, it has been brought to the
attention of the Administrator  that  as
Subpart J is now written,  a fluid cataly-
tic cracking unit incinerator waste-heat
boiler  is an affected facility subject  to
the standard limiting emissions  of par-
ticulate matter. Thus, if an owner or op-
erator installs an Incinerator waste-heat
boiler, that boiler must comply with the
standard on participate emissions.
  An   incinerator   waste-heat   boiler,
however, is an emission  control device
which   reduces  emissions  of  carbon
monoxide from a fluid catalytic cracking
unit catalyst  regenerator. It was not
EPA's  intent  that  Installation  of  an
emission control device to reduce carbon
monoxide emissions  would then require
installation of another  emission control
device  to reduce participate emissions.
Rather, the intent  was to consider the
fluid catalytic cracking unit catalyst re-
generator together  with any associated
incinerator waste-heat boiler in terms of
controlling participate emissions. If an
incinerator  waste-heat  boiler   which
burns  additional liquid or solid fossile
fuel is in use, an increase in total par-
ticulate emissions would  be  permitted.
consistent with good control of particu-
late emissions  from the combustion  of
that increment of fuel. Accordingly, fluid
catalytic  cradking   unit  incinerator
waste-heat  boilers  have  been  deleted
from the list of affected facilities. This
amendment of Subpart J, however, is not
a change in the intent of the  existing
standard of performance  limiting emis-
sions of participate matter.
         PUBLIC PARTICIPATION

  As prescribed by  section 111  of the
Clean Air Act  as amended, this proposal
of standards of performance  has been
preceded by the  Administrator's deter-
mination that  refinery sulfur recovery
plants contribute significantly to air pol-
lution which causes or contributes to the
endangerment of public health  or wel-
fare. By publication of this determina-
tion in this issue of the FEDERAL REGISTER
he adds petroleum  refinery  sulfur re-
covery plants to the list of affected facili-
ties under the source category of petro-
leum refineries. In accordance with sec-
tion 117 of the Act, publication of these
proposed  standards was  preceded  by

  (c) For the purpose of determining
compliance with 8  60.104(a), Method 11
shall be  used  to determine the concen-
tration of BUS and Method 6 shall be
used to determine  the  concentration of
SO*
  (1) If Method  11  is. used, the gases
sampled shall be  introduced into the
sampling train at approximately atmos-
pheric  pressure.  Where  refinery  fuel
gas lines are operating  at pressures sub-
stantially above atmosphere, this may be
accomplished  with a now control valve.
If  the line pressure  is high  enough to
operate  the sampling  train  without a
vacuum  pump, the pump may be elim-
inated  from  the  sampling train.  The
sample shall be drawn from a point near
the centroid  of the  fuel  gas  line.  The
minimum  sampling  time  shall  be 10
minutes and the minimum sampling vol-
ume 0.01 dscm (0.35 dscf ) for each sam-
ple. The arithmetic average of two sam-
ples of equal sampling time shall con-
stitute one run. Samples shall be taken
at  approximately  1-hour Intervals. For
most fuel gases, sample times exceeding
20  minutes may result in depletion of the
collecting  solution, although fuel gases
containing low concentrations of hydro-
gea sulfide may necessitate sampling for
longer periods of time.
   <2> If Method g is  used,  Method I
shall be used tot velocity  traverses and
Method 2 for determining velocity and
volumetric flow rate. The  sampling site
for determining  SO*  concentration by
Method 3 shall be the same as for deter-
mining volumetric flow rate by Method
'2. The sampling  point in the duct for
determining  SOi  concentration  by
Method 6 shall be at the centroid of the
cross section if the cross sectional area
is less than 5 m* (54 ft*) or at a point no
closer to the walls than 1 m (30 'niches)
if the cross sectional area is 5  m* or more
and the centroid is -more than one meter
from the wall. The sample shall be ex-
tracted at a rate proportional to the gas
velocity at. the sampling point. The mlni-
'mum sampling time shall  be  10 minutes
and the minimum sampling volume 0.01
dscm (0.36 dscf)  for each sample. The
arithmetic  average of two  samples  of
equal sampling time 'shall  constitute one
run.  Samples shall be taken  at approx-
 imately one-hour intervals.
   (d) For the  purpose of determining
compliance with  §60.104(b), Method  6
shall be used to determine the concentra-
tion of SO, and Method 15 shall  be used
to determine the concentration of HaS
and reduced sulfur compounds.
   (1)  If Method 6 is used, the procedure
outlined in paragraph (c) (2)  of this sec-
tion shall be followed  except that each
run shall span a minimum of four con-
secutive hours  of continuous sampling.
A number of separate samples may  be
taken for each run, provided the total
sampling time of these samples adds up
to a minimum of four consecutive hours.
Where more than one sample is used, the
average SO, concentration for the run
shaU be calculated as the  time weighted
average of the SO, concentration for each
sample according to the formula:
to the gas velocity at the sampling point.
Each run shall span E, minimum of four
consecutive hours  of  continuous sam-
pling. A number of separate samples may
be taken for each run provided the total
sampling time of these samples adds up
to a minimum of four consecutive hours.
Where more* than one sample Is used, the
average  moisture content for  the  run
shall be calculated  as the time weighted
average of the moisture content of each
sample according to the formula:
 Where:
 Cn=8Oi concentration for the run.
  W= Number of samples.
 Ca,"BOi concentration for sample i.
 ta,.= Continuous sampling time of sample i.
  5"= Total continuous sampling time of all -V samples.

   (2)  If  Method 15 is  used, each run
 shall consist of 16 samples taken over a
 minimum of  four hours.  The sampling
 point shaU be at the centroid of the cross
 section of the duct if the cross sectional
 area Is less than  5m'  (54 ft ')  or at .a
 point no closer to the walls than 1 m (30
 Inches) if the cross sectional area Is 5
 m° or more and the centroid is more than
 1 meter from the wall.  To insure mini-
 mum residence time for the sample inside
 the sample lines, the sampling rate shall
 be at least 3 liters/minute (0.1 ff/min) .
 The SO, equivalent for each run shall be
 calculated as the arithmetic average of
 the SO, equivalent of each sample dur?
 ing the run. Reference Method 4 shall be
 used to determine the moisture content
 of the gases. The sampling point for
 Method 4 shall be adjacent to the sam-
 pling point for Method 15. The  sample
 shall be extracted at a rate proportional

 new reference method as follows:

   BOUBC2&5

   1. Principle and applicability.  1.1 Princi-
 ple. A gas sample is extracted from the emis-
 sion source and diluted with clean dry air.
 An aliquot of the  diluted sample ia  then
 analyzed for  hydrogen sulflde (HdS). ear-
 bbnyl sulflde (COS), and carbon dlsulfide
 (CSi) by gas  chromatographlc  (OC)  sep-
 aration  and flame  photometric  (FPS)  de-
 tection.
   1.2 Applicability. This method is applicable
 for determination of hydrogen sulfide, car-
 bonyl sulflde,  and  carbon dlsulflde  when
 specified by an applicable subpart.
   2. Range and sensitivity. 2.1 Range. The
 maximum limit of the PPD for each sulfur
 compound is dependent on the sample size.
 For a 1  ml sample the upper  limit is  about
 10 ppm. It may  be  necessary  to dilute gas
 samples from sulfur recovery plants hundred-
 fold (100:1), resulting in an upper limit of
 about 1000 ppm for each compound.
   2.2 .The minimum  detectable  concentra-
 tion of the PPD is also dependent on sample
 size and would be about 0.5 ppm for a l ml
 sample.
   3. Interferences. 3.1 Moisture Condensation.
 Moisture condensation  In  the sample de-
 livery system, the analytical column, or the
 PPD burner block can cause losses or inter-
 ferences. This potential is eliminated by heat-
 Ing the  sample line, and by conditioning the
 sample  with dry dilution air to lower  its
 dew point below the operating temperature
 of the  GC/FPD  analytical system prior to
 analysis.
   S3 Carbon Monoxide and Carbon Dioxide.
 CO and CO» have a  substantial densensltiz-
 Ing effect on the detector even after 10:1 dilu-
 tion. This potential interterenc is eliminated
 by elutlng CO and  COi with the "air peak"
 prior to elutlon of any sulfur compound.
   3.3 Elemental Sulfur. The condensation of
 sulfur vapor in the sampling lines can lead to
 eventual coating and even blockage of tfce
 sample  line. This problem can be eliminated
 along with the moisture problem by heating
 the sample line.
   4. Precision. 4.1 Calibration Precision. A
 series of three consecutive Injections of the
 same calibration gas, at any dilution, should
 product results which do not vary by  more
 than ±3% from  the mean of  the three in-
 jection.

  4.2 Calibration Drift. The calibration drift
determined from the  mean, of three injec-
tions made at .the beginning and end of any
8-hour period should not exceed ±3%.

The sample probe should be fabricated from
a suitable length and diameter of stainless
steel tubing.
  6.1.2 Sample line—0.48 cm (3/16 Inch) in-
side diameter Dekoron FEP Teflon1  tubing,

 following procedures shall be completed be-
 fore sampling is initiated.
   7.1.1  Plowmeter  calibration  and  leak

 proceduree shall be employed to verify the
 accuracy and/or integrity of an fiowmeters,
 sample lines, and connections. For compo-
 nents under negative  presure  (lines and
 connections upstream  of the sample pump),
 a leak test is performed using  the  sample
 pump to pull a vacuum. Attach the probe
 »nd of the  sample line to a manometer or
 vacuum  gauge,  start  the pump and pull
 greater than 60 "•""  (2 In.) Hg vacuum. Close
 off the pump outlet, then stop the pump and
•ascertain that there IB no leak for 6 minutes.
 'For  components subject to positive pressure,
 teak tests shall be performed at each Joint by
                                 applying a liquid (detergent in water,  for
                                 example) which will foam In the presence of
                                 aleak.
                                   Since the complete  dilution system and
                                 OC/FPD Is calibrated prior to and following
                                 each  test,  the precise  calibration of each
                                 component is not  critical. However,  these
                                 components should be verified to be operat-
                                 ing properly. This  verification can be per-
                                 formed  by observing the response of flow-
                                 meters or of  the OC output to changes In
                                 flow rates or  calibration gas concentrations
                                 and ascertaining  the response to be within
                                 predicted limits. If any component, or If the
                                 complete system falls to respond in a normal
                                 and predictable manner, the source of the
                                 discrepancy shall be .identified and corrected
                                 before proceeding.
                                   7.1.2  Mass  flowmeter calibration—Since.
                                 all sample calculations are based on the  ac-
                                 curacy of air flow measured by  the mass
                                 flowmeters, It is essential that  the cross-
                                 calibration check of Section 6.4.2 be followed.
                                   7.13  Prior to any sampling run, calibrate
                                 the system using  the procedures set forth in
                                 Section 8. If more than one run is performed
                                 during any 24-hour period, a calibration need
                                 not be performed prior to the  second and
                                 any subsequent runs. The  calibration must,
                                 however, be verified as  prescribed In Section
                                 8, after the last run made within the 24-hour
                                 period.

at a constant rate. When the temperature to
constant, calibration -gases covering a  wide
range of known concentrations can be  gen-
erated by varying and accurately measuring
the flow rate of diluent gas passing over the
tubes.  These calibration gases are  used to
calibrate the OC/PPD system and the dilu-
tion system.
  8.3 Calibration Procedure.  Assemble the
permeation tube calibration apparatus as de-
picted In Figure 15-3. Insert the permeation
tubes Into the glass tube chamber. Check the
bath temperature to assure agreement  with
the  calibration temperature  of the tubes
within  ±1* C. A temperature of SO*  C Is
recommended-for the sulfur gas tubes. Allow
several  hours tor the tubes to equilibrate.
When equilibrated, vary the flow rate of di-
luent air flowing over the  tubes to  produce
the desired concentrations for calibrating the

  8.4 Operating Condition for OC/fPD Sys-
tem; The operation parameters  for the OC/
FPD system are as follows: nitrogen carrier
gas flow rate of 100 cc/mlnute, exhaust tem-
perature of 110" C. detector temperature of
106* C, oven  temperature of 40* C, hydro-
gen flow rate of 80 cc/mlnute,  oxygen flow
rate of 20 cc/mlnute, and sample flow rate of
80 cc/mlnute.
  8.S Calibration  of  OC/PPD Analysis Sys-
tems.  Generate a  series of three or  more
known concentrations  spanning the  linear
range  of the RPD (approximately 0.05 to 1.0
ppm)  for each sulfur compound anticipated
to be present In the gas stream analyzed. By-
passing  the  dilution system.  Inject these
standards  Into  the OC/FPD  analyzers  and
monitor the responses. Three Injects for each
concentration must yield the precision de-
scribed In Section 4.1; Failure to attain this
precision Is an Indication of a problem In
the calibration or analytical system. Any such
problem must be identified and corrected-be-
fore proceeding. Peak heights,  rather than
Integrated areas,  have proven  satisfactory;
however,  Integrated  areas may be required
for alternate columns or Instrumentation.
  8.5.1 Calibration curves—Plot  the GC/FPD
responses In current (amperes)  versus their
causative  concentrations  In  ppm  on  log-
log coordinate graph paper for each  sulfur
compound calibrated.
  8.6 Calibration  of. Dilution System. Gen-
erate  a known concentration  of  hydrogen
sulfide  using the permeation  tube system.
Adjust  the  flow rate of diluent air for the
first dilution stage so that the desired level
of dilution  Is approximated. Inject the di-
luted calibration gas Into the  OC/FPD and
monitor Its response. Three Injects for each
dilution must yield the precision described
in Section 4.1. Failure to attain this  preci-
sion in this step is an indication of a problem
In the  dilution system. Any such problem
must be Identified and corrected before pro-
ceeding. Using the calibration curve for H^S
(developed  under 8.5.1), determine the di-
luted calibration gas concentration in ppm.
Then, calculate the  dilution factor  as the
ratio of the calibration gas concentration
before  dilution to  the diluted  calibration
gas  concentration determined  under this
paragraph.  Repeat this procedure for each
stage of dilution required.
S.Sampling  and analysis procedure.
  9.1 Sampling. Insert the sampling  probe
Into the test port making  certain that  no
dilution air enters  the. stack  through the
port. Begin  sampling and dilute the sample
approximately 10:1  using the  dilution sys-
tem shown In Figure  15-1. Note  that the
precise  dilution factor Is that which  Is de-
termined in paragraph 8.6. Condition the en-
tire system with sample for a minimi^ of 16
minutes prior to commencing analysis.
  02 Analysis. The sample value la actuated
for one minute in which time  an aliquot of
diluted sample Is Injected  onto separation
column.  The valve to then deactivated for
the remainder of the analysis cycle in which
time the sample loop IB refilled and the sep-
aration column continues to be flushed. The
elutlon time for each compound  will be de-
termined during calibration.
  9.3 Sample Run A  sample consists of  one
analysis  (injection).    v-
10. Post-test procedures.
   10.1  Recallbratlon. After each run, or after
a  series of runs made within  a 24-hour pe-
riod, perform a  partial  recalibratlon using
the procedures in Section 8.  Only H.J5 (or
other permeant)  need be used  to recalibrate
the GC/FPD analysis system  (8.4)  and  the
dilution  system  (8.5).
   10.2  Determination of  Calibration  Drift.
Compare  the calibration  curves  obtained
prior  to  the runs to the calibration curves
obtained under paragraph  10.1. The calibra-
tion drift must not exceed the limits set forth
in paragraph 4.2. If the drift exceeds this
limit, the intervening run or runs shall be
considered not valid.
11. Calculations.
   11.1  Determine the concentrations of  hy-
drogen sulfide, carbonyl sulfide, and carbon
dlsulfide detected in each sample directly
from the calibration  curves.
   11.2 Sulfur Dioxide Equivalent.  For each
sample the  concentrations of hydrogen sul-
fide, carbonyl sulfide, and carbon disulflde
are totaled  and  the sum expressed as sulfur
dioxide using the following equation:

STANDARDS OF PERFORMANCE FOR NEW
        STATIONARY SOURCES
Iron and Steel Plants: Basic Oxygen Process
               Furnaces
  Notice Is hereby given that under sec-
tions 111, 114, and 301 of the Clean Air
Act, as amended, the Administrator is
proposing amendments to the standards
of performance for basic oxygen process
furnaces (BOPF).
  SUMMARY OF PROPOSED AMENDMENTS

  The  proposed  amendments  to  the
standards  of  performance  for  BOPP.
facilities would limit the opacity of emis-'
sions from  the control  device,  require
monitoring of operations of the control
device, and clarify the term "startup" as
it applies to BOPF facilities. Compliance
\rith  the proposed opacity limits  would
be  determined by conducting observa-
tions  in  accordance  with  Reference
Method 9. The continuous monitoring of
operations is specific to venturi scrubber
emission control equipment because all
presently planned facilities will be con-
trolled by  venturi scrubbers. The pro-
posed monitoring provisions require con-
tinuous monitoring of the pressure loss
across the throat of the scrubber and the
water supply pressure to the scrubber. As
the provisions of 40 CFR 60.11 (c)  apply
to BOPF facilities, "startup" means the
setting into operation of a BOPF  which
has been out of production  for a con-
tinuous time period of eight hours or the
setting into operation of a relined BOPF.

             BACKGROUND

  On June 11, 1973 (38 FR 15406),  the
Administrator proposed as Subpart N to
40  CFR Part 60, standards of perform-
ance  for new basic oxygen process fur-
naces (BOPFs). The proposed standards
limited participate matter emissions to no
more than 50 mg/dscm (0.022 gr/dscf)
and to less than 10 percent opacity  ex-
cept for two minutes in any one  hour.
Commenters on the'proposed standards
pointed out the inappropriateness of the
two minutes per hour exemption for the
cyclic steel production  process and  the
unachievability of the level of the pro-
posed opacity  standard.  Evaluation of
the comments on the proposed standard
led EPA to conclude that further  study
was required for development of ade-
quate provisions. On March  8,  1974 (39
PR 9308), the Administrator  promul-
gated the standard of performance  limit-
ing emissions from new BOPFs to less
than 50 mg/dscm; however, the opacity
standard and the attendant  continuous
monitoring  requirement were not pro-
mulgated at that  time.  The  opacity
standard was reserved pending study of
 (1) the reasons for the observed varia-
tions in the opacity of emissions from
well-controlled  facilities  and- (2)  the
effect that exempting periods of startup,
shutdown,  and malfunction from  ap-
plicability  of opacity standards  would
have on the level of the opacity standard
and the need for a time exemption.
  On November 12, 1974 (39 FR 39872),
EPA revised Reference Method 9 and the
general provisions  applicable to opacity
standards  of   performance.  Reference
Method 9,  the  method for determining
compliance with opacity standards, was
revised to require that opacity  observa-
tions be recorded at 15-second intervals
with a minimum of 24 observations (six
minutes), to obtain sufficient  observa-
tions to ensure acceptable accuracy. The
use of sets of  opacity observations (or
six-minute average opacity values) pre-
cludes  a single  high reading from being
considered  a   violation.  In  addition,
§ 60.11 (e) was added to the general pro-
visions to provide a means for an owner
or operator to petition EPA to  obtain a
higher opacity standard for any facility
that demonstrates compliance with the
mass standard  concurrent with failure
to achieve the opacity standard. Section
60.11(e) allows opacity standards to be
established at  levels which reflect the
maximum expected effects of the normal
range of operating variables and stack
diameters at well-controlled new facllii
ties.
  In light of the' Method 9 revisions and
the questions on the appropriate emis-
sion limitation and format for the opacity
standard, additional opacity data  were
obtained and the bases and rationale for
an opacity standard for BOPFs  were
thoroughly reevaluated. The reevalua-
Uon included consideration of the effects
on opacity of process variations,  of varia-
tions  in performance characteristics of
control devices, and  of  definition  of
startup periods  for BOPFs. The proposed
opacity standards  are established  at
levels  which are  achievable  by  well-
maintained and properly operated con-
trol equipment capable of reducing emis-
sions to the level  of the concentration
standard, 50 mg/dscm (0.22  gr/dscf).
Copies of the report on the data' bases
and  rationale for  the  proposed opacity
standard may be obtained upon written
request from the EPA Public Informa-
tion Center (PM-215), Environmental
Protection  Agency,  Washington,  D.C.
20460 (specify:  Background Information
for an Opacity Standard of Performance
for Basic Oxygen  Process  Furnaces in
Iron and Steel Plants).
ENVIRONMENTAL AND INFLATIONARY IMPACT

  Opacity  standards are  set  at levels
which ensure proper operation and main-
tenance of  the control system, but which
do not  require use of a more efficient
system. The opacity standards  and the
continuous monitoring requirements pro-
posed herein do not impose any addi-
tional  significant requirements or  costs
over those  required to comply  with the
concentration standard. Therefore, this
proposal is not considered a major action
under  the Inflationary Impact State-
ment (ITS) program and  no ns is re-
quired.  The environmental impacts of
the standards of performance for BOPFs
also are incurred in complying  with the
concentration standard. During the de-
velopment  of the  concentration stand-
ard, the intermedia effects of the stand-
ard were assessed and determined to be
negligible. No additional intermedia ef-
fects would be incurred in complying with
opacity standards for BOPFs. Therefore,
a  formal environmental impact state-
ment has not been prepared. The envi-
ronmental impact of the proposed opac-
ity standards is beneficial as the stand-
ards  would  ensure compliance  of  new
BOPFs with the concentration standard
throughout their operational life.

       DATA BASE FOR A STANDARD

  The standard of  performance limits
emissions from all new  basic  oxygen
process furnaces to less than 50 mg/dscm
(0,22 gr/dscm). Emissions'from  basic
oxygen process furnaces can  be con-
trolled to this level .by use of  a well-
designed and operated high  energy ven-
turi scrubber or an electrostatic precipi-
tator. In the development of an opacity
standard  for BOPFs, opacity observa-
tions were conducted  at six facilities ac-
cording to the procedures of Method 9
(39 FR 39872). Because of a known dif-
ference between the particle size distribu-
tions, and hence light scattering proper-
ties,  of emissions  from bottom blown
BOPFs and top blown BOPFs, the opacity
of emissions  from  both type furnaces
were  investigated  in the  background
study on a standard.
  The facilities observed in the study
were  representative of several  control
levels based  on available   paniculate
matter emission data and an engineering
judgment of the current condition of the
control system. The condition of the con-
trol system was assessed on  the basis of
review of operating parameters,  design
parameters, and maintenance condition
of the control system. From the observa-
tion of six faculties,  it was  noted  that
higher emissions occurred at the begin-
ning  of the  steel  production cycle for
both types of control systems. The higher
opacity emissions are attributable to the
greater evolution  rate of  participate
matter and the lower gas temperature at
the start of the oxygen blow as well as a
lag in the response of the control device.
For  scrubber-controlled top or botton
blown BOPFs the  six  minute average
opacity levels observed at  the start of
oxygen blow  were  less than 20 percent,
and the six minute average opacity levels
during the remainder of the cycle were
less  than 10  percent opacity.  Electro-
static precipitator  controlled facilities
exhibited opacity levels less than 30 per-
cent during the start of oxygen blow and
levels less than 16 percent during the
remainder of the  cycle. The difference
between the  opacity levels observed for
the two  types of  control systems  pri-.
marily reflects differences in diameter of
discharge stacks rather than significant
differences in the performance.

  RATIONALE FOR THE PROPOSED STANDARD

  Section 111 of the Act requires EPA to
set emission standards which reflect "the
degree of  emission limitation achievable
through application of  the  best system
of emission reduction which  (taking into
account the  cost of achieving such re-
                              FgDEttAl OECISTEQ, VOL. 42, NO. 41—WEDNESDAY1, MARCH 3, 1977

ductton) the Administrator  determines
has been adequately demonstrated." The
standards  of  performance require an
owner or operator to conduct a perform-
ance test after the initial startup of an
affected facility to ensure that the con-
trol system was properly designed and
installed. Section lll(e) of the Act re-
quires that new sources continue to be in
compliance with the standards through-
out their operational life. Opacity stand-
ards are established in conjunction with
mass  or concentration  standards as  a
means of ensuring that control equip-
ment  is  adequately  maintained  and
properly operated  at all times between
performance tests.
  In EPA's judgment, the opacity levels
associated with well-designed and oper-
ated facilities differed by type of control
system due to design features. Therefore,
selection of the emission limitation for
the standard required  consideration of
whether the level would ensure proper
operation and maintenance of all facili-
ties. In the development of the proposed
standard EPA  considered several  alter-
native regulatory approaches. The alter-
natives  considered  included  opacity
levels based on data from electrostatic
precipitator-controlled  facilities,  sep-
arate  opacity  limitations  for  electro-
static precipitator-controlled and scrub-
ber-controlled  facilities, and an opacity
level based on  data from scrubber-con-
trolled  facilities. An opacity  standard
based  on performance of electrostatic
precipitator-controlled systems was not
selected because the standard would not
require proper operation  and  mainte-
nance  of  venturi  scrubber-controlled
facilities. In addition, the steel industry
currently has no plans for the construc-
tion of any new electrostatic precipita-
tor-controlled BOPF  facilities, thus this
standard would not  accomplish its in-
tended purpose. Setting separate opacity
standards for  the  two control  systems
was also rejected  because only  one of
the control systems  is expected  to  be
used. Thus the proposed opacity stand-
ard  is  based  on  the  performance  of
scrubber-controlled   facilities.  Should
any affected BOPF be controlled with an
electrostatic  precipitator  and  comply
with the participate limit of 50 mg/dscm
but not the opacity limits,  a separate
opacity limit would  be established for
that facility under 40 CFR 60.11 (e). The
provisions  of   40  CFR  60.11(e)  allow
owners or operators of sources which ex-
ceed the opacity standard while concur-
rently   achieving   the  concentration
standard to request  establishment of a
specific opacity standard  for  that fa-
cility.
  The  proposed standard would limit
peak  opacity which occurs  at the begin-
ning  of the cycle  and the opacity over
the remainder  of the cycle. The opacity
limit for the beginning of the  cycle  is
necessary because  of the increased par-
tlculate loading and  gas density at the
startup of the operation. Emissions dur-
ing the period  of startup of the produc-
tion  cycle  are not excluded from  the
opacity standard as  a  "startup"  under
the provisions  of 40 CFR 60.11 (c)  be-
 cause emissions during this period are
 subject  to the concentration standard
 and are controllable.
   The proposed standard would  limit
 emissions  during the beginning of the
 production cycle to less than 20 percent
 opacity  and emissions  over the remain-
 der of the cycle to  less than  10 percent
 opacity. To'simplify  enforcement, the
 opacity standard would allow the period
 of higher opacity  emissions to occur
 once per steel production cycle. Restric-
. tion   of  the  higher  opacity  emission
 period to  the beginning of toe produc-
 tion cycle would require the observer  to
 synchronize  observations  with  shop
 operations.  In addition,  the proposed
 standard could be enforced more readily
 at facilities with several furnaces ducted
 to a single, common control system.
   Standards of performance  for new
 isources  established  under  section 111  of
 the Clean Air Act reflect emission limits
 achievable with the  best  adequately
 demonstrated systems  of emission re-
 duction  considering 'the  cost, of such
 systems.  State implementation  plans
 (SIP's)  approved or promulgated under
 section 110 of the Act, on the other hand,
 must  provide for  the  attainment  and
 maintenance  of national  ambient air
 quality standards (NAAQS) designed  to
 protect  public  health  and welfare. For
 that purpose SIP's must in some cases
 require  greater emission reductions than
 those required by standards of perform-
 ance for new sources. In addition, States
 are free under sectional 16 of the Act  to
 establish more'stringent emission limits
 than those established  under section 111
 or those necessary to attain or maintain
 the NAAQS under section 110. Thus, new
 and existing  sources may  in some cases
 be subject to limitations more stringent
 than  EPA's  standards of  performance
 under section 111.

  STANDARDS OF PERFORMANCE FOR
      WEW STATIONARY SOURCES
       Sewage Sludge Incinerators
  Subpart 0 sets forth  standards of per-
formance for new, modified, and  recon-
structed sewage sludge Incinerators in
sewage treatment plants. The standards
limit emissions of participate matter to
0.65 g/kg dry sludge Input (1.30  Ib/ton
dry sludge input) and visible emissions
to  20 percent opacity.  The State of
Alaska recently requested EPA to revise
8 60.150 of the regulation. The basis of
the request is  that Incinerators  which
are small enough to meet the needs of
small communities  in  Alaska and also
comply  with the  particulate  matter
standard are not available, and the dis-
posal of sewage sludge  in landfills is not
a viable option because of permafrost
and other factors  resulting  in  landfill
problems  (shallow  and soft landfills).
The proposed amendment would exempt
Incinerators with a capacity of less than
140 kg/hr  (300 Ib/nr) dry sludge pro-
vided that disposal  by land application
or sanitary landfill  are shown to  be in -
feasible because of freezing conditions.

             BACKGROUND
  The standards of performance for sew-
age sludge incinerators  were promulgated
March 8, 1974 (39 PR  9308), under sec-
tion 111 of the dean Air Act. Section
111 directs the Administrator to estab-
lish  standards  of performance for new
stationary sources which reflect the de-
gree  of  emission limitation  achievable
.through the application of the best sys-
tem of emission reduction which (taking
into account t"he cost of achieving such
reduction) the Administrator determines
has been adequately demonstrated. The
best system  of  emission  reduction  for
sewage  sludge  incinerators  (multiple
hearth and fluid bed reactor type Incin-
erators) was determined to be low energy
venturi scrubbers.
  At  the time the  standards were pro-
mulgated EPA was developing a  stand-
ard for murcury emissions from  sewage
sludge  incinerators and  guidelines  for
municipal  sludge   management.  The
standard limiting   mercury  emissions
wus promulgated under section 112 (Haz-
ardous Air Pollutants) of the dean Air
Act on October 14, 1975 (40 PR 48302),
and the proposed guideline was Issued for
public comment on June 3, 1976, under
the title "Technical Bulletin on Munici-
pal Sludge Management: Environmental
Factors."
   Incineration Is  just one  of  several
methods available  for sludge disposal.
The standards, which  limit emissions of
mercury and particulate matter, insure
that adequate emission control systems
are employed when Incineration  Is used
 ss the method of sludge disposal. Incin-
eration is  only  a  volume  reduction
method. After incineration, the ash, ei-
ther dry or In scrubber water, remains
to be-disposed of to the land. Ash dis-
posal must be designed to protect ground
water,  to prevent dust, and to insure no
erosion to surface waters.
             INVESTIGATION
  In investigating Alaska's request, EPA
contacted the vendors of sewage sludge
incinerators  and found that multiple
hearth or fluid bed reactor type Incin-
erators which can achieve the particu-
late  matter standard are not commer-
cially available below a  size capacity of
140 kg/hr (300 Ib/nr). This means that
Incineration  would not  be  a  disposal
option  where units smaller  than  140
kg/hr are needed. Since the unique prob-
lems in parts of Alaska also prevent dis-
posal by land, application or sanitary
landfill, sludge disposal cannot  be ac-
complished in  an  environmentally ac-
ceptable mnaner under existing regula-
tions. EPA concluded  that a revision to
the standards of performance for sludge
incinerators is appropriate.
  In developing a revision to the stand-
ard to accommodate the unique problems
in parts of Alaska, EPA intends that the
proposed exemption not create an Incen-
tive  to utilize small incinerators which
would not be covered under the stand-
ard1.  To avoid this situation the proposed
exemption applies only where an owner
or operator can demonstrate to the sat-
isfaction of the Administrator that land
application and sanitary landfills are not
feasible disposal methods for the sewage
sludge. The size exemption is based on
the  capacity of the waste water treat-
ment plant rather than the incinerator
In order to prevent constructing multiple
small  incinerators  rather than larger
units which would  be  subject  to  the
standard.
  The  proposed amendment of § 60.150
would not affect applicable national mer-
cury emission  standards under § 61.50
which currently regulates mercury emis-
sions from all sludge incinerators. These
standards are not subject to the exemp-
tion because control  of mercury emis-
sions can be  achieved by ordinances or
statutes which prevent mercury-bearing
material from being introduced into the
municipal waste treatment system.

STANDARDS OF PERFORMANCE FOR NEW
        STATIONARY SOURCES
   Sewage Treatment Plants: Correction
  On January 26,  1977  (42  FR 4863),
EPA published a proposed amendment
to Subpart 0 of 40 CFR Part  60. By this
notice 'EPA makes certain administrative
changes to the proposed amendment and
requests that interested  persons  com-
ment on  the amendment as published
here rather than as published on Janu-
ary 26, 1977. The amendment proposed
here retains the exemption for any sew-
age sludge incinerator which is located
at a  municipal waste treatment  plant
having  a  dry sludge capacity below 140
kg/hr (300  Ib/hr) and where it is not
feasible to dispose of the sludge  by land
application or in a sanitary landfill be-
gcause of  freezing conditions. However,
the amendment proposed here does not
require the owner or operator ta'demon-
strate to the satisfaction of the  Admin-
istrator that such conditions exist, as was
required by the amendment proposed on
January 26.  Rather, -the procedures al-
ready established under 40 CFR 60.4 and
60.5 are available for an owner or oper-
ator of  a sewage sludge incinerator to re-
quest an EPA determination  of whether
such an incinerator is an affected-facility
under these regulations.
  Comments  on the proposed  amend-
ment  published  here will be  due on
March  15, 1977, which-is the same due
date as for the'amendment published on
January 26,1977.

  In  40 CFR Part 60, it  is proposed to

incinerator  which combusts  the sludge
produced by municipal sewage treatment
plants except any such incinerator which

plant having a dry sludge capacity below
140 kg/hr (300 Ib/hr)  and  where it is
not feasible to dispose of the sludge by

treatment plant or  the dry  sludge ca-
pacity of  the sewage sludge incinerator,
whichever is greater, is used.

          KRAFT  PULP MILLS
    Standards of Performance for Nea
           Stationary Sources
  Notice is hereby given that under the
authority of section 111 of the Clean Air
Act, as amended,  the  Administrator  Is
proposing standards of performance for
new and modified kraft pulp mills. The
Administrator also is proposing to amend
Appendix A, Reference Methods, in Part
60  by  adding a  reference^ method for
the measurement of total reduced sulfur
(TRS)  emissions  and   an alternate
method for the measurement of partic-
ulate matter.

         PROPOSED STANDARDS
  The proposed standards would limit
emissions  of particulate  matter from
three affected  facilities  at kraft pulp
mills. The limits are:  (1)  0.10 gram per
dry standard cubic meter (g/dscm) for
recovery furnaces, (2) 0.15 gram  per
kilogram of air-dried pulp (g/kg ADP)
for  smelt  dissolving  tanks,  (3) 0.15
g/dscm for  limp  kilns  when  burning
natural gas, and (4) 0.30 g/dscm for lime
kilns when burning oil. Visible emissions
from recovery furnaces would be limited
to 35 percent opacity.
  Under the proposed standards, TRS
emissions  would  be limited to  5 parts
per million (ppm)  by volume from seven
affected  facilities:  Digester  systems,
brown stock  washer systems, multiple-
effect evaporator systems, black  liquor
oxidation   systems, recovery furnaces,
lime kilns,  and condensate stripper sys-
tems. In addition, a  TRS standard of
0.025 g/kg ADP  is proposed for smelt
dissolving tanks
        ENVIRONMENTAL IMPACT

  The  proposed standards would reduce
particulate  emissions  from  new kraft
pulp mills more than 99 percent below the
levels that  would  result from no control'
and more than 50 percent below the av-
erage levels that  are being achieved by
typical existing facilities in the United
States. Emissions of TRS would be re-
duced by more than 95 percent below the
uncontrolled  levels and  more  than  80
percent below the average levels for ex-
isting sources.
  TRS emissions  from kraft pulp mills
are  extremely  odorous, and there  are
numerous instances of poorly controlled
kraft mills creating public odor prob-
lems. The proposed standards  include
limitations on TRS  emissions,  rather
than on the intensity of odors produced
by  kraft pulp mills, because this  course
of  action would  ensure more objective
and efficient enforcement. The proposed
standards  would  prevent  odor problems
from most newly constructed kraft pulp
mills, except in the immediate vicinity
of the mills on occasions when meteoro-
logical conditions produce downwash  of
stack  plumes. 33&a proposed standards
would substantially reduce ground level
ambient ate concentrations  of particu-
late matter around new kraft pulp mills
below current levels found  around ex-
isting mills.
  The secondary  environmental  impact
of the  proposed standards would  be
minor. No  additional solid  waste han-
dling  or disposal problems would  be
caused by  the standards because  the
additional particulate  matter collected
from  recovery  furnace systems, smelt
dissolving tanks,  and lime kilns  can be
recycled to  the kraft  pulping  process.
Increased water demand  and treatment
would  be slight  because mill  process
water can be used in scrubbing systems
for lime kilns, and smelt dissolving tanks,
and the scrubbing system effluent could
be recirculated to  the  kraft  pulping
process  with no increased effluent.  The
increased mud  washing necessitated by
the standard could  increase water de-
mand. A relatively small amount of par-
ticulate matter, sulfur dioxide, and ni-
trogen oxides would be discharged into
the air if the power plant that supplies
the additional electrical power required
by the standards  is fired with fossil fuel.
            ENERGY  IMPACT
  The energy requirements  of the pro-
posed standards  have been evaluated.
Compared  to the requirements  of the
average State standards, the  incremental
energy that would be required to control
all new. modified, and  replaced affected
facilities at kraft pulp  mills  by 1981 has
been estimated  at an equivalent of about
1,440,000 barrels of Number 6 fuel oil per
year. The magnitude of this requirement
indicates that  the  proposed standards
would not have a major impact on the
imbalance between  national energy de-
mand and domestic  supply.
  The incremental energy requirements
of the proposed standards would  be gen-
erated by the use of fans or pumps to
circulate exhaust gases or scrubbing liq-
uids  through control  devices, and the
direct consumption of natural gas or fuel
oil to incinerate exhaust gases or main-
tain  process conditions that reduce the
generation of pollutants. The incremen-
tal energy represents an increase of ap-
proximately 4.3  percent above the process
energy requirements for new kraft pulp
mills,
          ECONOMIC IMPACT
  The proposed regulations  could affect
an estimated 17  million tons of kraft
pulping capacity by  1981. About  a third
of that capacity would be affected as a
result of mill capacity expansions. The
remainder would be affected  via replace-
ment of depreciated designated facilities.
It Is projected that the equivalent of 33
new mills or expansions at existing mills,
with a capacity of 500 T ADP/day, will
occur through 1980.  Replacement of ex-
isting depreciated designated facilities
will result at an estimated 35 mills.
  Total incremental  investment  costs-
through 1981 are projected to be $104
million. The fifth-year annualized costs,
including depreciation  and interest, are
estimated at $33 million. About a third of
these costs would be incurred by mills ex-
panding capacity, while  the remainder
would be incurred by mills replacing de-
preciated designated facilities.
  The costs that new, modified, and re-
constructed kraft pulp mills would incur
to comply with the proposed standards
are considered reasonable. No difference
in impact among mill sizes  could be dis-
tinguished, and the proposed standards
would not have an adverse impact  on
either small or large mills. The capital re-
quired for typical new mills would be in-
creased by less than 2  percent, and the
price of semi-bleached  kraft pulp would
be increased by less than 2 percent. The
effect  the  proposed standards  would
have on demand and supply of kraft pulp
and on the future  growth of  the kraft
pulp industry is considered negligible. It
is emphasized that the costs are consid-
ered reasonable for new and  modified
sources and that it is not implied that the
same costs apply to the retrofitting  of
existing sources. The review of the eco-
nomic impact has shown that the pro-
posal is not a  major action under the
Inflationary  Impact Statement  (IIS)
program and no IIS is needed.
  SELECTION OP SOTTRCE CATEGORY AND
         AFFECTED  FACHITIES
   Section 111 of the Act directs the Ad-
ministrator to establish standards of per-
formance for stationary sources that may
contribute significantly to  air pollution
which causes or contributes to the en-
dangerment of  public health or welfare.
Kraft pulp mills are a major source  of
TRS compounds and particulate matter
emissions. TRS compounds can have an
adverse effect on public welfare, and par-
ticulate matter can have an adverse ef-
fect on public health and welfare. Kraft
pulp mills were selected for the develop-
ment of standards  based  on  expected
growth of the industry and the beneficial
impact  that would  result from the ap-
plication of best technology for air pollu-
tion control. Kraft  pulping has histori-
cally been a rapidly growing industry,
with a growth rate of 5.5 percent per year
between 1958  and  1975.  The  annual
growth rate for 1976 to 1978 is projected
to be 2.5 percent, but estimates show that
the growth rate may return to a higher
rate in 1979.
  TRS emissions from kraft pulp mills
are composed primarily of hydrogen sul-
flde, methyl mercaptan, dimethyl sulfide,
and dimethyl  disulfide. These  sulfide
compounds  are extremely  odorous and
exhibit odor threshold concentrations  of
no more than a few parts per billion. A
study of the national social and economic
impacts of odors performed in 1971-1973
by Copley International Corporation for
EPA found that the pulp and paper in-
dustry ranks in the upper quarter of all
odor sources in terms of strength and
public objection to the odors. The emis-
sions from each pulp mill surveyed in the
study affect an average of 44,000 persons
over an area of approximately 100 square
miles. The survey of 184 local  air pollu-
tion control agencies in the United States
ranked the pulp and paper source cate-
gory as the fastest growing odor prob-
lem.

 process  control' atone. The
 cost for caustic addition to the scrubber
 Ss small where the casistic is not part of
 •fche make-up in the kraft causticlzing
 system. Accordingly, the proposed stand-
 ard of 5 ppm TRS, four-hour  average,
 would require both the best process con-
 &rols for lime kiln operation and caustic
 addition to the scrubber, or an equivalent
 system.
   In developing the proposed standards,
 KPA carried out six tests for participate
 emissions from lime kilns. In each case
 the control device for participate matter
 was a medium pressure  drop scrubber,
 She most widely used control technique in
 4he domestic industry. However, one do-
 mestic kraft pulp mill controls  particu-
 late emissions with an electrostatic pre-
 cipltator. Based on design  parameters
 and emission data supplied by the opera-
 tor of this ESP, this system achieves an
 emission level significantly  below that
 determined by EPA for medium  pressure
 drop scrubbers. However, the waste gases
 from the digester system and multiple-
 effect evaporator system, which  could
 more economically be incinerated  in the
 lime kiln, are processed in a  separate
 incinerator at this facility to control TRS
 (emissions. The cost and energy penalties
 tor the separate incinerator are relative-
 ly large. The  Industry has  commented
 that it may not be feasible to incinerate
 the waste gases from other sources in a
 kiln controlled by an ESP, because gases
 may explode in the ESP when flameouts
 occur in the kiln. Solutions to this poten-
 tial problem, such as automatic diverting
 of inlet gases away from the kiln when
 & flameout occurs, have been considered,
 but there is at this time no demonstrated
 technology that will ensure that  explo-
. sions would not occur.
   In arriving at the proposed  standard
 for particulate matter  emissions from
 lime kilns, EPA considered the  alterna-
 tives of a medium pressure drop  scrubber
 alone, an ESP alone, and both particulate
 control  systems operated  In series.  A
 separate incinerator  to  control  TRS
 emissions from digester systems, mul-
 tiple-effect evaporator systems, and con-
 tSensate stripper systems was included in
 4he two alternative ESP  systems. EPA
 concluded that the relatively large in-
 crements In cost and energy usage asso-
 ciated with the ESP  alternatives were
 aot justified by the additional particulate
 control  gained beyond that achievable
 .With a  medium pressure drop  scrubber
 cJone. Consequently, the proposed par-
 Uculate matter standard  would require
 a medium  pressure drop scrubber (ap-
 proximately 30 Inches water gauge), or
 equivalent.
   EPA  has determined  that an oxygen
 concentration in  the  gas stream  meas-
 ured after the lime Win control  device
 to excess of 10 percent represents exces-
 sive air inleakage; therefore,  the pro-
 BHwed standards require (Siat all  meas-
 urements of particulate matter and TRS
 Siat, have an oxygen concentration  in
 (szoizss of 20 percent be corrected to  10
 percent osiygen.
                  SMELT DISSOLVING TAPTK
            Smelt dissolving tanks discharge par-
          ticulate  matter  comprised  of -finely
          divided smelt particles that are entrained
          in the steam emitted from the tank. On
          an uncontrolled basis, the quantity of
          particulate emissions is  small in com-
          parison with that from recovery furnaces
          and lime  kilns.  TRS emissions can be
          generated in the dissolving tank or in a
          scrubbing device that collects particulate
          matter, depending primarily on the sul-
          flde content of water used to dissolve the
          smelt and to perform  the  scrubbing.
          Standards in terms of concentration of
          pollutants are not considered appropri-
          ate for smelt dissolving tanks because the
          effluent stream is primarily ah- and  no
          correction for oxygen content and dilu-
          tion air is possible to ensure effective en--
          forcement.
            Particulate emissions from smelt dis-
          solving tanks are controlled by using wire
          mesh   demister  pads  or  low  energy
          scrubbers. The scrubbers remove particu-
          late  matter  much  more- effectively,
          though the energy requirements and op-
          erating  costs  are  higher  than  for
          demisters.  The  proposed  particulate
          standard  for smelt   dissolving  tanks
          would  require the use  of low energy
          scrubbers, or equivalent systems, and is
          supported by four EPA tests on two types
          of low energy scrubbers. The proposed
          TRS standard for smelt dissolving tanks
          would  prevent the use  of water highly
          contaminated with sulndes for dissolving
          the smelt and for particulate scrubbing
          systems.
                      OTHER SOURCES
            Approximately one-quarter of the total
          uncontrolled TRS emissions from a typi-
          cal kraft pulp mill are generated by the
          digester  system, brown stock  washer
          system, black liquor  oxidation system,
          multiple-effect evaporator  system, and
          condensate stripper system.  Ineffective
          control  of these facilities could have a
          large impact on localized odor problems.
          The effluent streams can be incinerated
          in the recovery furnace, the lime kiln, or
          a separate incinerator  to  oxidize most
          of the TRS. The  quantity of auxiliary
          fuel required for incineration is greatly
          reduced if incineration is performed in
          the recovery furnace and the lime fclin.
          If the noncondensable gases  from the
          brown stock washer system and the black
          liquor oxidation system are Incinerated,
          for  example,  in  the recovery  furnace,
          some  auxiliary  fuel may  be required.
          However, the noncondensable gases from
          the digester system, multiple-effect evap-
          orator system, and condensate stripper
          system would not require additional fuel
          if Incinerated in the lime kiln as part of
          the primary ah* feed to the kiln. The pro-
          posed standard of 5 ppm TRS, four-hour
          average, for each of these five affected
          faculties would  require  incineration in
          the recovery furnace and the lime kiln,
          or equivalent.
                     OPACITY STANDARD

            An opacity standard is  proposed  for
          recovery  furnace  systems  to ensure
proper operation and maintenance of the
partclulate control device.  No  opacity
standards are  proposed for lime  kilns
and smelt dissolving  tanks,  which fre-
quently generate persistent  plumes of
condensed water  vapor. The  effluent
plume is so greatly dispersed by the time
the vapor plume disappears that the ob-
served-opacity would  not be  as effective
an indicator  of the performance of the
patriculate  control  system  as  other
parameters. .Monitoring the operating
parameters of the control system would
be more effective.
     STATE IMPLEMENTATION  PLANS

  It should be  noted that standards of
performance for new sources established
under  section 111  of  the Clean Air Act
reflect emission limits  achievable with
the best adequately demonstrated sys-
tems of emission reduction  considering
the cost of such systems. State imple-
mentation plans  (SIP's) approved or
promulgated under section 110 of the'Act.
on the other  hand, must provide for the
attainment and maintenance of national
ambient air quality standards (NAAQS)
designed  to  protect public  health and
welfare. For that purpose SIP's must in
some cases require greater emission re-
ductions than those required by stand-
ards of performance for new  sources.
In addition, States are free under sec-
tion 116  of the Act  to establish more
stringent  emission limits than those es-
tablished  under  section 111  or  those
necessary to attain  or  maintain the
NAAQS under section  110.  Thus, new
and existing  sources may in some cases
be subject to limitations more stringent
than  EPA's  standards  of performance
under  section 111.
       TESTING, MONITORING, AND
            RECORDKEEPDJG
  Under  the proposed  standards,  per-
.formance tests for TRS emissions ac-
cording to Reference Method  16  pro-
posed  herein would be required for all
affected facilities. Performances-tests for
particulate matter emissions from  re-
covery  furnace systems, lime kilns, and
smelt  dissolving  tanks  would  also be
required.  Particulate matter emissions
would be  measured by Reference Meth-
ods  1  through 5. Method 17  (in-stack
filter)  is being proposed as an  alterna-
tive method to measure particulate emis-
sions from the recovery furnace. It is
being  proposed in Appendix A, Refer-
ence Methods,  because the  Agency in-
tends  to  also propose Method  17 as a
reference method to measure  particu-
late matter from grain  elevators.
  The proposed standards include pro-
visions for continuously monitoring the
opacity of visible emissions discharged
from  recovery  furnaces.   To  ensure
proper operation  and  maintenance of
scrubbers Installed  on lime kilns and on
smelt dissolving tanks, provisions are in-
cluded for monitoring the pressure drop
across  the 'scrubber and the scrubbing
fluid supply pressure to the  scrubber.
  Where  emissions from  the  
-------
multiple-effect evaporator oycSssn, black
ffiouor oxidation  sysJwa. or condensate
stripper are incinerated m a device other
$han a Bme kfln  or recovery furnace, it
is proposed that the firebox temperature
of the device be monitored.
   A  requirement for  the  continuous
monitoring of TRS emissions from the
recovery furnace and lime kiln  is also
proposed. The specifications for continu-
ous TRS monitors are not being proposed
at this time because they have not been
completely developed. However, the de-
velopment  of these  specifications  are
imminent and they are  expected to be
promulgated at the time that the kraft
pulp m^i standards of performance are.
promulgated,
  A requirement  to monitor the oxygen
concentration of the gas  stream on a
dry.basis after the control device is be-
ing proposed for the  lime kiln and re-
covery -furnace. The montorlng of  oxy-
gen concentrations is necessary to cor-
rect the TRC and particulate concen-
trations for the lime  kiln  and recovery
furnace when the oxygen concentrations
in the respective  gas streams are in ex-
cess of 10 percent and 8 percent oxygen.
  Records of performance testing meas-
urements, continuous  monitoring system
measurements, and  monitoring  device
measurement would have to be retained
for at least two years  following the date
of  the  measurement*  by owners or
operators subject to  the provisions of
this subpart.  This requirement  is in-
cluded under. 8,60.7 (d) of. the regulation.
         PUBLIC PARTICIPATION
  As prescribed by section 111, this pro-
posal of standards of performance has
been  preceded by the  Administrator's
determination that kraft pulp mills con-
tribute  significantly  to  air  pollution
which causes or contributes to the en-
dangerment of public health or welfare
and by his publication of this  determi-
nation  in  this  issue of  the  FEDERAL
REGISTER. In accordance with section 117
ot the Act,  publication of these proposed
standards was preceded by consultation
with  appropriate  advisory committees,
Independent  experts,  and  Federal  de-
partments  and agencies.

METHOD   16—SEMICONTINTJOTJS  DETERMINA-
   TION or STJUTJB EMISSIONS FEOM STATION-
   ART SOURCES
 1. Principle and applicability
   1.1 Principle.  A gas sample  Is  extracted
from the emission source and diluted  with
clean dry air. An aliquot of the diluted sample
Is then  analyzed for  gaseous sulfur com-
pounds b; gas  chromatographlc (QC) sepa-
ration and flame photometric (FPD)  detec-
tion. . Two  GC/FPD  analytical systems
equipped with suitable columns are used for
resolution  of both low and high  molecular
weight TBS compounds.
   .1.2 Applicability. This method IB applica-
ble  for determination of  TBS compounds
when specified  by an  applicable subpart.
 2. Range and sensitivity
   3.1 Range. The  maximum limit of the
FPD for each  sulfur  compound Is about  1
ppm. This limit Is expanded by dilution of
 the  sample gas before  analysis. Kraft mill
 gas  samples are normally  diluted tenfold
 (10:1), resulting In an upper limit of about
 10 ppm for each compound.
   2.2  Sensitivity. The minimum detectable
 concentration of the FPD is less than 50 ppb.

 3. Interferences

   3.1  Moisture condensation. Moisture con-
 densation in the sample delivery system, the
 analytical column, or the FPD burner block
 can  cause losses or Interferences. This poten-
 tial  is eliminated by heating the sample line,
 and by conditioning  the sample with dry
 dilution air to lower its dew point below the
 operating temperature of the OC/FFD ana-
 lytical system prior to analysis.
   3.2  Carbon monoxide and carbon dioxide.
 CO and CO, have a substantial desensitizing
 effect on the detector even  after 10:1 dilu-
 tion. This potential Interference is eliminated
 by elutlng CO  and  CO,  with the "air peak"
 prior to elution of any sulfur compound.
   8.3  Particulate matter. Particulate matter
 In gas  samples can cause  Interference by
 eventual clogging of the analytical system.
 This  interference is eliminated by use of a
 filtered probe described in Section 5.1.1.

 4. Precision

  4.1  Calibration precision. A series of three
 consecutive injections  of the same calibra-
 tion  gas, at any  dilution, should  produce
 results  which do not vary  by more  than
 ±3%  from the mean of the three Injections.
  4.2  Calibration  drift.  The  calibration
 drift  determined from the  mean of three
 Injections  made at the beginning and  end
 of any 8-hour period should not exceed :t3 Tc.
 6. Apparatus

  5.1.1  Probe. Figure  16-1   illustrates  the
 probe used in lime kilns and other sources
 where significant amounts   of  particulate
 matter  are present. The probe  is designed
 with  the deflector shield placed between the
 sample and the gas inlet holes and the glass
 wool  plugs  to reduce clogging  of the niter
 and possible adsorption of sample gas. The
 exposed portion of the probe between  the
 sampling port and the  sample line Is heated
 with heating tape.

  8.4  Operating  Conditions  for  QC/FPD
Systems.
  8.4.1  Low-Molecular. Weight Sulfur Com-
pounds — The operating parameters  for the
QC/FPD  system used  for low molecular
weight compounds are  as follows:  nitrogen
carrier gas flow rate of 50 cc/mlnute, exhaust
temperature of 110° C, detector temperature
of 105° C, ,oven temperature  of 40*  C, hy-
drogen flow rate of 80  cc/mlnute. oxygen
flow rate of 20 cc/mlnute, and sample flow
rate between 20 and 80 cc/mlnute.      '
  8.4.2  High -Molecular Weight Sulfur Com-
pounds — The operating parameters  for the
QC/FPD system for  high molecular  weight
compounds are the same as In 8.4.1. except:
oven temperature of 70'  C,  and  nitrogen
carrier gas flow of 100  cc/mlnute.
  8.5  Calibration of QC/FPD Analysis  Sys-
tems.  Generate  a series of three  or more
known concentrations  spanning  the linear
range  of the FPD (approximately 0.05 to 1.0
ppm)  for each sulfur compound anticipated
to be  present  In the gas stream  analyzed.
Bypassing  the  dilution  system, Inject these
standards  Into the GC/TPD  analyzers and
monitor the responses. Three injects for each
concentration  must yield the precision de-
scribed In  Section 4.1. Failure  to attain this
precision  is  an Indication  of  a problem  in
the  calibration  or  analytical  system.  Any
such problem  must  be Identified and  cor-
rected  before  proceeding.  Peak  heights.
rather than Integrated areas, have  proven
satisfactory;  however, Integrated areas  may
be required for alternate columns or instru-
mentation.
  8.5.  Calibration Curves — Plot  the  GC/
FPD responses in current (amperes)  versus
their causative concentrations in  ppm on
log-log coordinate graph paper for each sul-
fur compound  calibrated.
  8.6  Calibration of Dilution  System. Gen-
erate a known  concentration of  hydrogen
sulfide using the permeation  tube  system.
Adjust the flow  rate of  diluent air for the
first dilution stage so that the desired level
of  dilution  is  approximated.  Inject  the
diluted is  approximated. Inject  the diluted
calibration gas Into GC/FPD-I and monitor
Its response. Three Injects for  each dilution
must yield the precision described in Section
4.1. Failure to  attain this precision  in  this
step Is an Indication of a problem  in the
dilution system.  Any such problem must be
Identified and  corrected before proceeding.
Using  the calibration  curve  for  ILS  (de-
veloped under  8.4.1)  determine the  diluted
calibration gas concentration In ppm. Then,
calculate the dilution factor as the ratio  of
the  calibration   gas  concentration  before
dilution to the diluted  calibration gas con-
centration determined under this paragraph.
Repeat this procedure for each stage of dilu-
tion required.

9. Sampling and  analysts procedure

  9.  Sampling.  Insert  the sampling probe
Into the  test  port making certain that no
dilution air enters the  stack through the
port. Begin sampling .and dilute the sample
approximately  10:1 -using the dilution  sys-
tem shown In Figura  16-9. Note that the
prectea dilution factor to that which Is deter-
 mined In paragraph 8.5. Condition the  en-
 tire system with sample for a minimum of 15
 minutes prior to commencing analysis.
   9.2  Analysis.  Allquots of  diluted sample
care Injected simultaneously  Into both GC/
 PPD analyzers for analysis. GC/FPD-I Is used
 to measure the low-molecular weight reduced
 sulfur compounds. The low molecular weight
 compounds Include hydrogen sulfide, sulfur
 dioxide, methyl mercaptan,  ethyl mercap-
 tan, and dimethyl sulfide. GC/FPD-n is used
 to resolve the high-molecular weight com-
 pounds. The  high  molecular  weight  com-
 pounds Include propyl mercaptan, butyl mer-
 captan, dimethyl disulfide, dlpropyl sulfide,
 and dibutyl sulfide.
   9.2.1  Analysis of Low-Molecular Weight
 Sulfur Compounds—The sample valve  is ac-
 tuated for one  to  three minutes In which
 time an aliquot  of diluted sample Is injected
 Into the  stripper  column  and  analytical
 column. The valve is then de-actuated for
 approximately fifteen minutes in which time,
 the analytical column continues to be fore-
 flushed, the stripper column Is backflushed,
 and the sample  loop Is  refilled. Monitor the
 responses. The elutlon  time  for  each  com-
 pound will  be  determined during calibra-
 tion.
   8.2.2  Analysis of High-Molecular Weight
 Sulfur Compounds—The procedure Is essen-
 tially the  same as above except  that no
 stripper column Is needed.
   9.2.3  Sample  Run—A sample run is com-
 posed of 16 individual analyses (injects) per-
 formed over a period of  not less than 3  hours
 or more than C hours.
  9.2.4  Observation for Clogging of Probe—
If reductions In  sample concentrations are
observed during.a sample run that cannot be
explained by process  conditions, the  sam-
pling must be Interrupted to determine if
the sample probe Is clogged with partlculate
matter. After each  run,  the  sample  probe
must be  Inspected  and,  if  necessary, dis-
mantled and cleaned.

10. Post-Test procedures
  10.  Recallbration. After each run, or after
a series of runs made within  a 24-hour pe-
riod, perform a partial recalibration using the
procedures In Section  8. Only HjS  (or other
permeant) need  be  used to recalibrate the
GC/FPD analysis system (8.4) and the dilu-
tion system (8.6).
  10.  Determination  of  Calibration  Drift.
Compare  the calibration curves  obtained
prior to the runs, to the calibration curves
obtained under paragraph 10.1.  The calibra-
tion drift must  not exceed the  limits set
forth in paragraph 4.2. If the drift exceeds
this limit, the Intervening run or runs shall
be considered not valid.

11. Calculations
  11.1   Determine the concentrations of each
reduced  sulfur compound detected directly
from the calibration curves.
  11.2   Calculation  of TRS. Total  reduced
sulfur will be determined for each analysis
made by summing the concentrations of each
reduced sulfur compound resolved during a
given analysis.

                                               introduction. Participate matter is not an
                                             absolute  quantity;  rather It  Is a  variable
                                             which is a function of temperature and pres-
                                             sure.  For  this  reason,  paniculate  matter
                                             emission  regulations and/or associated  test
                                             methods  must define or take cognizance of
                                             the temperature and pressure at which par-
                                             ticulate matter Is to be measured. If tempera-
                                             ture is not defined, and If the effect of tem-
                                             perature upon the quantity of partlculate In
                                             an effluent gas Is unknown, then  the par-
                                             ticulate emission regulation may be variable.
                                             The range of pressure which exist from source
                                             to source is of negligible importance.
                                               In Method 5,  250*  F is established as a
                                             nominal reference temperature. Thus, where
                                             Method 5 is specified under an applicable
                                             subpart, paniculate  matter  Is  defined with
                                             respect to temperature. In order to maintain
                                             this  Indicated  temperature, Method  6  In-
                                             cludes  a heated glass sample  probe and a

      ond heating -oystem, end sample  o&
stack temperature.
  This method describes an in-eteck sampling
system  and  sampling iwoosdures for use
where particulate matter concentrations era
independent of temperature. It may be used
to conduct performance  tests under 40 CFB
00.8 within specified conditions, or when ap-
proved by the Administrator.

1. Principle tm& applicability
   1.1 Principle. Particulate matter Is with-
drawn lEOklnetically from a gas stream and
collected on o gloss fiber  filter maintained at
stack temperature. The  particulate  matter
mass is determined gravimetrically after re-
moval of uncomblned water.
   12 Applicability. This method applies to
the measurement of particulate matter emis-
sions from stationary sources and is used to

         formance standards,  when specifically pro-
         vided for in .an applicable subpart  of the
         standards. This  method  is not applicable
         •when stack gases are saturated with water
         vapor or ^rhen the projected cross-sectional
         ore  of the  probe  extension-filter  holder
         assembly  (when inserted  halfway  Into the
         stack)  covers more than  3%  of the stack
         cross-sectional area (see Section 4.12).

            2.1  Sampling train. A  schematic  of the
         sampling train used in this method is shown
         to Figure  17-1.  Construction details  for
         many, but' not all, of the  train components
         are given In AFTD-0581; for changes from the

   The operating and maintenance procedures
 for many of Che sampling train components
 ore described  m  APTD-0576.  Since  correct
 usage is Important in  obtaining  valid re-
 sults, oil users should read the APTD-0576
 document and adopt the operating and maln-
 tenace procedures outlined in it, unless oth-
 erwise specified herein.
   2.1.1  Probe nozzle—Stainless steel (316)
 with sharp, tapered leading edge. The angle
 of taper shall be £30°  and the taper shall be
 on the  outside to preserve a constant in-
 ternal diameter. The probe nozzle shall be of
 the button-hook or elbow design, unless oth-
 erwise approved by the Administrator. ISie
 nozzle shall ba constructed  from seamless
 stainless steel, tubing. Other configurstions
 and construction  material may be used sub-
 ject  to  approval from the Administrator.
   A  range of sizes suitable  for  Isoklnetle
 campling should  be available, e.g., 032 cm
 (% in.) up to 1.27 cm (Vi in.) (or larger if
 higher volume sampling trains are used) in-
 side diameter (ID) nozzles in Increments of
 0.16 em (Ms in.).  Each mozzle shall be cali-
 brated according  to the procedures outlined
 in the calibration section.
  • 3.13  Filter  Bolder.  The  in-stack  filter
 holder shall he constructed of boroslllcate or
 quartz  glass or stainless  steel;  if a gasket
 is used, it shall be made  of slllcone rubber,
 teflon, or stainless  steel.  Other holder and
 gasket materials may be used with approval
 from the Administrator. The filter holder
 shall be designed IS)  provide a positive csal
 against leakage from the outside or around
 «S»o filter.
            2.13  Probe Extension—Any suitable rigid
          probe extension may be used after the filter
          holder. Flexible tubing may. also be used be-
          tween  the probe  extension  and  the con-
          denser.
            2.1.4  Pltot tube—Type S, or other-device
          approved by the Administrator, attached to-
          probe extension to allow constant monitoring-.
          of the stack gas velocity. The face openings
          of the pilot tube and the probe nozzle shall
          be adjacent and parallel to each other, not.
          •necessarily in the same plane, during sam-
          pling. The free space between the nozzle and
          5>ltot tube (sea Figure 17-1) shall be at least
          1.8 cm {0.76 In.). The free  space, shall be
          oet based on o 1.8 cm (0.5 in.) ID nozzle; If
          the sampling train is designed for sampling
          at higher flow rates than that, described; In
          APTD-0581, thus  necessitating the use  of
          larger sized nozzles, the largest sized nozzle -
          shall be used  to set the free space. In addi-
          tion, to iriiTUTniM> aerodynamic interactions
          between the  pitot tube  and  filter holder,
          there shall be a distance of at least 3 Inches
          between the center line of the pitot tube Im-
          pact openings and the leading edge of the
          alter holder (see Figure 17-1).
            The pitot tube must  meet  the  criteria
          specified in Method 2, and be calibrated sepa-
          rately (I.e., apart from Its assembly configu-
          ration) according to the procedures outlined
          in that method for the calibration of Isolat-
          ed Type S pitot tubes.
            2.1.6  Differential pressure gauge—Inclined
          manometer capable of  measuring  velocity
          head xrtthln 10% of the minimum measured
          volus or ±0.013 pum (0.0008 in.), whichever
     is greater. Selow a differential pressure  of
     1.3 mm (O.OS in.) water guage, mlcromanom-
     eters with sensitivities of 0.013 mm (0.0005
     In.)  should be used. However, mlcromanom-
     etere are not easily adaptable to field condi-
     tions and are not easy to use with pulsating
     flow. Thus, methods or other devices accep-
     table to the Administrator may be used when
     conditions warrant.
       2.1.6  Condenser—Any system that cools
     the sample gas stream (e.g., implngers con-
     nected in series, as In Method 5) and allows
     measurement of both the water condensed
     and the moisture leaving the condenser, each
     to within 1 ml or  1 g. The moisture leaving
     the  condenser  can be measured either by:
     (1)  monitoring the temperature and pres-
     sure at the exit of the condenser and  using
     Dalton's law; or (2) passing the sample gas
     stream through a silica gel trap with exit
     gases kept below 20' C («8° F) and determin-
     ing the weight gain.
        If means other than  silica gel  are used'
     to determine the amount of moisture leav-
     ing  the  condenser, it is recommended that
     silica gel still be used between the condenser
     system  and pump to prevent moisture con-
     densation in the pump and metering devices.
        2.1.7  Metering  system—Vacuum   gauge,
     teak-free pump, thermometers capable  of
     measuring temperature to within 3° C (5.4°
     F), dry gas meter with 2% accuracy, and re-
     lated equipment, or equivalent, as required
     to maintain an Isoklnetic sampling rate and
     to determine sample volume. Sampling trains
VACuuvutuizing  metering  systems  designed   for
 UNE higher flow  rates  than that: described  in
     AFTD-0581 or  APTD-O576 may be used pro-
     Tided  that the specifications in section 2 of
     this method are  met. When  the  metering
     system- Is  used in conjunction with a pitot
     tube, the system shall enable checks of iso-
     kinetic rates.
        2.1.8  Barometer—Mercury,  aneroid,   or
     other  barometers  capable  of measuring at-
     mospheric pressure to within 2.5 mm Hg (0.1
     In. Hg). In many cases, the barometric read-
     ing may be obtained from a nearby weather
     bureau station, in which -case the station
     value  (which Is the absolute barometric pres-
     sure)  shall be  requested and an adjustment
     for elevation differences between the weather
     station and sampling point  shall be applied
     at a rate of minus 2.5 mm  Hg (0.1 in. Hg)
     per 30 m (100 ft) elevation Increase or vice
     versa'for elevation decrease.
        2.1.9;  Gas density  determination  equip-
     ment—Temperature and pressure gauges and
     gas analyzer as described In Methods 2  and
     3.
        2.1.10   Temperature and. pressure gauges—
     If Dalton's law is  used, to monitor tempera-
     ture- and. pressure at condenser outlet.  The
     temperature, gauge/shall, have an accuracy
     of 1°  C' (2° F). The pressure gauge shall be
     capable of measuring, pressure to within 2.5
     mm. Hg- (0.1 in. Hg). If silica gel is used in
     the condenser system the  temperature and
     pressure must be measured before the silica.
     gel component.
        22.  Sample recovery:
        32.1  Probe nozzle brush—Nylon bristles
      with stainless steel wire handle. The brush
     shall  be properly  sized and shaped to brush
      out the probe nozzle.
        222  Glass  wash bottles—Two.
        22.3  Glass  sample storage containers—
     Chemically resistant, boroslllcate glass  bot-
      tles, for acetone washes, 500-ml or 1,000 ml.
     Screw cap closures shall  be teflon rubber-
     backed  liners  or of such construction so as
     to be  leak free and prevent chemical  attack
      from  the acetone. (Narrow mouth glass' bot-
     tles have been found to be less prone  to
      leakage.) Other types of containers must be
     approved by the Administrator.
        22.4  Petrt  dishes—For  filter   samples;
      glass  or polyethylene, unless otherwise speci-
      fied by the Administrator.

4. Procedure

  4.1  Sampling.  The sampling shall be con-
ducted  by  competent personnel experienced
with this test procedure.
  4.1.1  Pretest preparation. All the compo-
nents shall t>e maintained and calibrated
according  to  the  procedure  described  In
APTD-0576, unless otherwise specified herein.
  Weigh approximately 200-300 g of silica gel
In  air tight containers to the nearest 0.5 g.
Record  the total  weight,  both silica gel and
container, on each container. Larger portions
of  silica gel may be  used, but care should
be  taken during sampling that  the gel Is not
entrained and carried out of Its holder.  As
an alternative, the silica  gel may be weighed
directly In its Implnger  or sampling holder
Just prior to train assembly.
   Check  niters  visually  against light  for
Irregularities and flaws or pinhole leaks. La-
bel filters of proper size on the back side near
the edge using numbering machine Ink.  As
an alternative, label the  shipping containers
 (glass or plastic  petrl dishes) and  keep the
filters In these containers at all times except
during sampling and weighing.
  Desiccate the filters at 20±6.6° C (68*10*
F) and ambient pressure for at least 24 hours
and weigh at 6 or more hour intervals to a
constant weight, i.e.,   0.5 mg change from
previous weighing, and record results to the
nearest  0.1 mg. During each weighing the
filter must not be exposed  to the laboratory
atmosphere for a period greater than 2 min-
utes and a relative humidity above 50S~C.
  4.1.2  Preliminary determinations.  Select
the sampling site and the minimum number
of sampling points according to Method 1 or
as specified  by the  Administrator. Make  a
projected area  model of the probe extension-
filter holder assembly,  with the  pltot tube
impact openings positioned along the center-
line of the stack, as  shown in Figure  17-2. If

.the estimated  cross-section blockage,  cal-
culated as  shown in Figure 17-2, exceeds 3
percent of the duct cross sectional area, then
either one of the following shall be done: (1)
a suitable out-stack filtration method can be
used instead of In-stack filtration; or (2) a
special in-stack assembly, designed to mini-
mize blockage effects, can be used. For de-
tails concerning the latter approach, consult
with the Administrator.

and the range of velocity heads using Meth-
od 2; determine the moisture content using

-------
                                                        PROPOSED HOES
   Select a nozzle slzeiased on tlte range of
 velocity beads such Oat it to not necessary
 to change the nozzle iBlae in order to main-
 tain isokinettc sampling rates. During the
 ran, do not change the nozzle  size. Ensure
 that the differential pressure gauge  Is capa-
 ble of measuring the minimum velocity iread
 value to within 10%, or as specified by the
 Administrator.
   •Select a probe extension length such that
 •11 traverse points can be sampled. Consider
 sampling from opposite sides for large stacks
 to reduce the length of probes.
   Select a total sampling time greater than
 or  equal  to the minimum  total sampling
 tune specified in the test procedures for the
 specific Industry such that the sampling time
 per point Is not less than 2 mln. (or  some
 greater time Interval if specified by  the Ad-
 ministrator) and the sample volume  taken.
 •will exceed the required minimum total gas
 «amp]« volume specified in  the test pro-
 cedures for the specific industry. The latter
 to based on an approximate average sampling
 imte. Note also that the minimum total sam-
 ple volume Is corrected to  standard condl-

   It Is recommended  that  half-integral or
 Integral numbers of minutes  be sampled at
 each point In order to avoid timekeeping er-
   In  some circumstances, e.g., batch cycles,
 tt may be necessary to sample  for shorter
 tJmea at the  traverse points  and to obtain
 •nailer gas sample volumes. In these cases,
 tte Administrator's approval must first be
 ebtalned.
   4.1.8  Preparation of collection train. Dur-
 ing preparation and assembly of the sam-
 pling train, keep all openings where  con-
 tamination can occur covered until Just prior
 to assembly or  until  sampling is  about to
 begin.     ^  -•               . . •
   If implngers are used to condense stack
 gas moisture prepare them as follows: place
 TOO ml of water In each of the first two 1m-
 plngerr.  leave the  third tmplnger empty;-
 and transfer approximately 200-300 g or more,
 tf necessary, of preweighed  silica  gel from
 Its container to the fourth Implnger;  alter-
 natively, if a balance is available in  the field,
 the silica gel can be weighed out in a tared
 Implnger. and Its weight gain determined In
 tbe field. Place the sOlca gel container in a
 dean place  for  later use in the  sample re-
 covery. If some means other than tmplngere
 to used to condense moisture, prepare  the
 •oodenser (and. if appropriate, silica gel for
 condenser outlet) for use.
   Using * tweezer or clean disposable surgi-
 cal  gloves,  place a  labeled (identified) and
 weighed  filter In the  filter  holder. Be sure
 that the filter is properly centered and  the
 gasket properly  placed co as not  to  allow
 the sample  gas stream  to  circumvent  the
 filter? Check filter for tears after assembly Is
 completed. Mark the  probe extension with
 beat resistant  tape or by some other method
 to denote the  proper distance  into the stack
 or duct for each sampling  point.
   Unless otherwise specified by the Adminis-
 trator, attach  a temperature  sensor to  the
 probe extension so  that the  sensor extends
 beyond the leading edge of the probe exten-
 sion and does  not touch any metal.  The sen-
 ear should  be positioned  at least 1.9  cm
 (0.75  tn.) from both the pltot tube and probe
 nozzle to avoid  interference  with the  gas
" «DW (see Figure 17-1).
   Assemble the train as In Figure 17-1, using
 .(tt applicable) a very light coat of sllicone
 grease on all ground glass Joints and greasing
 only the outer portion (see APTD-0576)  to
 avoid  possibility of  contamination by  the
 •nicone grease. Place crushed Ice  around the
 tmptngen (if  applicable).
   4.1.4  Leak  check   procedure—After  the
                has  been assembled, a teak
•check of the filter holder shall be conducted
as follows: Plug the Inlet to the probe noa-
Ete with a material that will be able to with-
stand the stack temperature;' Alternatively,
the proble nozzle can be removed and the In-
let to the filter holder plugged.  Insert the
holder into the stack and wait approximately
6 minutes (or longer, if necessary)  to allow
the system to come to equilibrium with the
temperature  of  the stack gas  stream. Turn
on the pump and draw a vacuum of at least
380 mm Hg (16  In. Hg). Determine the leak-
age rate,  If any. A leakage .rate In excess of
4% of the average sampling rate or 0.00067
m'/mln. (0.02 cfm), whichever is less, is un-
acceptable.
  The' following leak check instructions  for
the sampling train described in APTD-0576
and AFTD-0681 may  be helpful. Start the
pump with  by-pass valve fully  open  and
coarse adjust valve completely closed. Par-
tially open   the  coarse  adjust  valve  and
slowly close the by-pass valve unto 880 mm
Hg (16 in. Hg) .vacuum is reached. Do not
•reverse direction of by-pass valve. If 880 mm
Hg (15 in. Hg) is exceeded, either leak check
at this higher vacuum or end the leak check
as shown below and start over.
  When the leak  check IB completed,  first
slowly remove the plug from the Inlet to the
probe nozzle  and  immediately turn off the
vacuum pump. This prevents the  water In
the  condenser from  being forced backward
and keeps  silica gel from being  entrained
backward.
  Leak checks  shall be conducted as de-
scribed whenever the train is disengaged, e.g.,
for silica gel or filter changes during the test.
prior to each test run,  and at the comple-
tion of each test run. If leaks are found to be
in excess of the acceptable rate, the test will
be considered invalid. To reduce lost time due
to leakage occurrences, it is  recommended
that leak checks be conducted between port
changes at the highest vacuum  reading
drawn during that sampling traverse.

   4.1 US Partlculate train operation—During
the  sampling run, maintain the tsoklnetic
sampling  rate to within 10% (unless other-
wise specified by the  Administrator)  of true
isoklnetlc.
   For  each run, record the data required on
the example data sheet shown in Figure 17-8.
Be sure to record  the initial dry gas meter
reading. Record the dry gas meter readings
-at the beginning and end of each sampling
time Increment, when changes in flow rates
are  made, and  when samplylng  is  halted.
•Take other data point readings at least once
at each sample point during each time incre-
ment  and additional  readings when  signifi-
cant changes (20%  variation in velocity bead
readings)  necessitate  additional adjustments
In flow rate. Level and zero the manometer.
   Clean {he portholes prior  to the test run
to minimize the chance of sampling  the de-
posited material. To begin sampling,  remove
the nozzle cap and  verify that the pltot tube
and probe extension are properly positioned.
Position the nozzle at the first traverse point
with the  tip pointing directly into the gas
stream. Immediately start the pump and ad-
just the flow to isoklnetlc conditions. Nomo-
graphs, which aid  In the rapid adjustment
of the laoElnetic sampling rate without ex-
cessive  computations, are available lor use
whenever the Type S pltot tube coefficient is
0.85±ti.02. and the stack gas equivalent den-
sity (molecular weight) to 29±4. AFTD-0578
details the procedure for using these nomo-
graphs. If C, and M4 are outside the above
stated ranges, do not use the nomograph un-
less appropriate steps (see Reference 7.7) are
taken to compensate for the deviations.
 " When  th» stack is under significant nega-
tive pressure (height of Implnger stem), take
care to close  the coarse adjust valve  before
inserting the  probe  into the stack. If 'neces-
sary, the pump  may be turned on with the
coarse adjust valve closed.
  When  the probe is in position, block off the
openings around the probe and porthole to
prevent unrepresentative  dilution of the gas
stream.
  Traverse the  stack cross section, as re-
quired by Method 1 or as specified by the
Administrator, being  careful  not  to  bump
the probe nozzle into the stack walls when
sampling near the walls  or when  removing
or Inserting the probe extension through the
portholes, to minimise chance of extracting
deposited material.

          KRAFT PULP MILLS
 Standards of Performance for New Station-
   ary Sources;  Extension  of  Comment
   Period
   On September 24, 1976 (41 FR 42012),
 the Environmental Protection  Agency
 (EPA)  proposed standards of perform-
 ance for the control  of  emissions from
 kraft pulp mills. The notice of proposal
 requested public comments on the stand-
 ards by November 22,1976. Due to a delay
 in the printing and shipping of the
 Standards Support and Environmental
 Impact Statement, sufficient copies of the
 document have  not been available to all
 interested parties in time to allow their
 meaningful review  and comment by No-
 vember 22. The public comment period is
 therefore being  extended to allow addi-
 tional time for  all interested  parties  to
 participate in this  rulemaking. EPA has
 received a request  from  the industry  to
 extend the comment period by 45 days
 through January 7,1977. An extension of
 this  length does  not.  however,  seem
 justified because the printing and ship-
 ping delay  has resulted in only a two-
 week delay in processing requests for the
 document. EPA has therefore determined
 that the comment period  will be ex-
 tended by three weeks and all comments
 postmarked by December 13,1976, will be
 considered.  Comments  should be sub-
 mitted (in  triplicate)   to the Emission

 STANDARDS  Of  PERFORMANCE  FOR
      NEW STATIONARY SOURCES
            Grain Elevators
  Notice is hereby given that under the
authority of section 111 of the Clean Air
Act, as amended, the • Administrator is
proposing standards  of  perfprmance for
new, modified, and reconstructed  grain
elevators.
          PROPOSED STANDARDS
-  The proposed  standards  would limit
emissions of  particulate  matter  from
eight affected facilities and the air pollu-
tion control devices on these facilities at
grain elevators. The  standards  apply to
farm elevators, country elevators, termi-
nal elevators, and commerical rice dryers
which  have grain leg capacities greater
than 352  cubic meters per hour (mVh)
(ca. 10,000  bushels hr> and to storage
elevators  at wheat flour mills,  wet corn
mills, dry corn mills  (human consump-
tion) ,  rice mills,  or  soybean extraction
plants. The standards are: (1)  0.023
gram per standard cubic meter  dry basis
(g/std. m! dry basis.) and zero percent
opacity from control devices on any af-
fected facility  except grain dryers;  (2)
zero percent opacity  from any truck un-
loading station, grain handling operation,
railroad  hopper car  loading station, or
railroad  boxcar loading station;  (3)  no
visible emissions from any railroad hop-
per car unloading station or railroad box-
car loading station ; '.4.' ten percent opac-
ity from any truck loading  station; (5)
ten percent opacity, except that  the opac-
ity may  not exceed fifteen percent dur-
ing  topping -off  operations,  from any
barge  or  ship loading station;  (6) zero
percent  opacity  from any  grain  dryer
(column dryers would be considered in
compliance  with  the standard  provided
the  diameters  of all  column plate per-
forations do not  exceed 2.1 millimeters
[mm]  [ca. 0.084  inch], and rack dryers
would be considered  in compliance pro-
vided all exhaust gases pass through a
50 or finer mesii  screen filter)  ; (7)  op-
eration of a leg which is  enclosed from
the top (including the receiving hopper)
to the center line of the bottom pulley,
and ventilation of at least 32.1 actual
cubic meters per  cubic meter  of  grain
handling  capacity (ca. 40 ftVbu)  to a
particulate control devict on both sides
of the leg and the grain receiving hopper,
at any barge or ship unloading station.
  ENVIRONMENTAL AND ECONOMIC IMPACT

  The proposed standards would reduce
the  uncontrolled  particulate matter
emissions from new  grain elevators by
more than 9S percent. Estimates for vari-
ous model grain elevators show that the
standards woold reduce particulate mat-
ter emissions to a level that is 67 to 94
percent less than the level required by
typical Stave standards. This reduction
In emissions resii&s  in  a significant re-
duction  of  embJEnt  concentrations of
particulate matter in the vicinity of grain
elevators. The maximum 24-hour average
concentration at a distance of 0.3 kilom-
eter (km) from the model facilities would
be reduced to a level that is 52 to 76 per-
cent lower than the maximum concen-
tration that results from control to the
level of typical State standards. By 1981,
the proposed standards would reduce the
total amount of particulate matter  emis-
sions  into  the  atmosphere by  21,000
megagrams per year (ca. 23,000 tons/yr).
  The secondary environmental impacts
of  the  proposed standards would be
minor. There would be no  Impact on
water pollution because only dry type col-
lectors would be used to control particu-  <
late emissions. Minimal additional solid
waste  handling  or  disposal problems
would be caused  by the standard.  Cur-
rently, approximately 68 percent of the
grain dust collected by emission control
devices  at  elevators is  returned to the
grain, 30 percent is  sold for use In feed
manufacturing, and 2 percent is disposed
of as solid waste. The additional  grain
dust collected by a more efficient control
device would either be  sold for feed or
landfilled. The proposed standards would
have  minimal adverse impacts on noise
and land-use considerations. A relatively
minor amount of particulate matter, sul-
fur dioxide, and  nitrogen  oxides would
be discharged into the atmosphere from
power plants supplying the additional
electrical power tfcat would be required to
operate  the control device  needed  to
achieve the  proposed standards.
  The  incremental  energy   required,
above the typical State standard require-
ments,  by  the proposed standards  to
control   all   new,  modified,  or recon-
structed grain elevators constructed by
1981 is  equivalent to about 2700 m' per
year  (ca. 17,000 barrels per year)  of
Number 6 fuel oil. This indicates that the
proposed standards would have a minor
impact  on the imbalance between  na-
tional energy demand and domestic sup-
ply. The energy requirements of the pro-
posed standards result from the use of
fabric filter control instead of the  exist-
ing cyclone  control  requirements. The
total  air pollution  control  energy that
would be required to meet the proposed
standards represents approximately 23
percent of the total  process energy re-
quirements of new grain elevators. This
is an increase of about 5 percent  above
the  energy presently needed  to  meet
typical State standard requirements for
new grain elevators.
  The proposed. standards would  affect
approximately 500 grain elevators in the
next five years. The incremental control
costs  of the  proposed standards  over
typical  State control  requirements  is
estimated to be $26 million in capital cost
in this five-year period and $5.5 million
in annual  costs in  the fifth year. The
proposed  standards would  result  in  a
total added production cost of 0.5 percent
based on a selling price of $68.20 per mj
(ca. $2.40 per bushel) for corn. This cost
includes the cost imposed by  the pro-
posed  standards on grain  production
from  the farm to the port terminal ele-
vator. The maximum cost added to the
grain as a result of the proposed stand-
ards  at an  individual  grain elevator
would be less than one cent per bushel.
The effect that the proposed  standards
would have  on supply arid demand of
grain and grain products and on  the
future growth  of  the  grain industry is
considered negligible.  In the  judgment
of EPA, these costs are considered rea-
sonable for  new,  modified, and  recon-
structed sources.
  EPA  has determined that this docu-
ment does not  contain a major proposal
requiring preparation of an Inflation Im-
pact  Statement under Executive  Order
11821 and OMB Circular A-107.
   SELECTION OF SOURCE CATEGORY AND
          AFFECTED FACILITIES
  Section 111 of the Clean Air Act di-
rects  the Administrator  to  establish
standards of performance for  stationary
sources that may contribute significantly
to air pollution which  causes or contrib-
utes  to the endangerment  of  public
health  or  welfare.  Also, under  section
109  of  the Act, particulate matter has
been designated as  a  criteria pollutant,
and  National  Ambient  Air  Quality
Standards (NAAQS) have been  set for
particulate matter.
  It is estimated that  the grain elevator
industry,  which consists of about. 7,900
grain elevators located nationwide, emits
550,000 megagrams per year (ca.  606,000
tons/yr)  of  particulate  matter. In  a
study  performed for  EPA by The  Re-
search  Corporation of  New  England,1
significant sources of particulate matter
were identified and ranked in order of
total emissions.  Four grain  handling
operations were shown to be significant
sources of particulate:  processing  was
ranked  fifth,   transfer  was   ranked
seventh,  cleaning  and  screening  was
ranked tenth,  and  drying was  ranked
number thirty-three among all  known
sources of particulate  emissions. In ad-
dition,  the report of the Committee on
Public  Works  of   the  United   States
Senate * listed grain elevators as a source
for  which  standards  of  performance
should be developed.
  Growth in  the grain  elevator and grain
processing industries  is expected to be
slow  since the per  capita consumption
of grain products is remaining constant
or decreasing. The total number of grain
elevators  is expected to decrease; how-
ever, the total throughput of grain is
expected  to  increase  slightly.  Of  the
processing plants,  only soybean process-
ors have significant incentive to invest in
new storage  capacity.  Soybean produc-
tion has increased over twenty-fold in
the United States  in less than 34 years.
Approximately  500 new,  modified,  or
reconstructed  grain  elevators are ex-

 $ected to be  constructed by  1981. This
 growth rate of about 100 grain elerators
 per year is considered to be significant.
   EPA has determined  that participate
 emissions from grain elevators contrib-
 ute significantly to air  pollution which
 causes or contributes to the endanger-
 ment of the public health. For this rea-
 son, the source category of grain eleva-
 tors has been selected  for establishing
 new source performance standards.
'  The  proposed standards would apply
 to affected facilities that handle wheat,
 corn, soybeans, milo,  rice,  rye, oats, or
 barley. These grains  were selected to be
 subject to the  standards  because they
 ore the primary grains produced in the
 United States.  There are several other
 grains  (e.g., millet), but these crops'are
 Crown and handled in small quantities.
 'therefore, the handling^ of these grains
 is not considered a significant source of
 particulate matter at this time.
   Animal pet food, and cereal manufac-
 turers; breweries; and feedlots also han-
 dle and process whole grain. These in-
 dustries were beyond the scope of the
 backgornud  industry  studies.  Conse-
 quently, no data are available on  these
 sources and they are not subject to the
 proposed standards.  In addition, there
 are relatively few plants in these periph-
 eral industries.
   Consideration was given to classifying
 an entire grain elevator, including all its
 various functions, as the affected facility.
 If this were done, however, modification
 
-------
 This gives a significant capital and oper-
 ating  cost  advan&age to  the  column
• dryer. EPA believe the majority of new,
 modified, or reconstructed dryers will be
 column dryers; however, new rack dryers
 may be installed In high throughput ele-
 vators because maintenance costs appear
 to  be  less for  rack  dryers in these
 applications.
  Emissions from grain dryers are dis-
 charged from an exhaust  area that is
 usually very  large. Therefore, it is  not
 technologically or economically  feasible
 to apply the usual particulate source test
 methods  designed  for measuring stack
 emissions to this source. Several attempts
 to carry out source tests were made by
 EPA and by operators of grain elevators.
 The data collected, however, can only be
 used as a guide in developing a standard
 due to the numerous difficulties encoun-
 tered in the measurement technique. The
 accuracy and precision of the technique
 are  not sufficient for determining com-
 pliance. EPA has concluded that methods
 for  measuring  mass particlate matter
 emissions  from  grain dryers  are  not
 available at t&is time. The only practical
 and feasible method of measuring par-
 ticulate matter  emissions from grain
 dryers is visible emission determinations.
  EPA considered several alternate con-
 trol systems for grain dryers in develop-
 ing the proposed standards. The alterna-
 tives considered for column dryers were
 no screen filter with a perforation size
 range of 1.25 to  2.1  mm (ca.  0.050 to
 0.084 inch) and a vacuum-cleaned screen
 filter  (50 mesh  and 100 mesh screen
 size).  The  alternatives considered  for
 rack dryers were a screen  filter (24-30
 mesh screen size) and a vacuum-cleaned
 screen  filter  (50  mesh and 100 mesh
 screen  size).  The  factors evaluated in
 considering these alternatives included
 the  amount  of emissions  (visible  and
 mass), capital costs, annual costs, energy
 requirements,  operating   and  mainte-
 nance problems, and  trends in the indus-
 try  to use certain types of  equipment.
 After  considering  all of these  factors,
 EPA concluded that  the  best system of
 emission reduction (considering costs) is
 a column dryer equipped with  column
 plate perforation diameters  of 2.1  mm
 (ca. 0.084 inch) or less and a rack dryer
 equipped with a 50  mesh screen filter.
 Both of  these  systems are  considered
 economically  reasonable  and   compa-
 rable in  control of  particulate matter
 emissions.
   A zero percent .opacity standard (based
 on six-minute averages) is proposed for
 all grain dryers. The owner or operator
 of  any column dryer would  be  consid-
 ered in compliance  with the standard
 provided the diameters  of  all  column
 plate perforations do not exceed 2.1 mm
 (ca. 0.084 inch) and the owner or opera-
 tor of any rack dryer  would be considered
 in compliance provided all exhaust gases
 pass through a 50 or finer mesh screen
 filter. EPA observed  five  column dryers,
 of  two different designs, with perfora-
 tion plate diameters ranging from 1.25 to
 2.1 mm (ca. 0.050 to  0.084 inch). A total
 of 126 six-minute opacity averages were
 obtained. EPA observed two rack dryers,
one equipped with a 50 mesh vacuum-
cleaned screen filter and the other with
no screen filter. A total of 5 six-minute
opacity averages were obtained at the
dryer equipped with the 50 mesh screen.
Based on the available data, EPA con-
cluded that a standard of zero percent
opacity can be achieved by the best sys-
tem of emission reduction  (considering
costs) for grain dryers.
    AIR POLLUTION CONTROL DEVICES

   EPA separately considered the capture
systems at various grain operations and
the air pollution control devices used to
remove the captured particulate matter
from the gas stream before discharge to
the atmosphere. The proposed standards
would require  air pollution  control de-
vices on all affected facilities at a grain
elevator, except  grain  dryers and some
types of dust-tight  grain  handling op-
erations. EPA measured particulate mat-
ter  emissions  according  to Reference
Method 5, except that the probe was not
heated, from eleven grain processes con-
trolled with fabric filters. EPA did not
measure emissions  from  cyclones, but
estimates that emissions from grain op-
erations controlled by cyclones average a
factor of 10 times those from fabric filter
control devices.  Based on these  data,
EPA has determined that the best dem-
onstrated  air  pollution control  device
(considering costs) for grain operations
is a fabric filter.
   EPA considered both mass and con-
centration units for the proposed stand-
ards. The  basic  difference is  that  a
standard which restricts the mass rate of
emissions  would limit the  total  mass
emitted, whereas a  standard with con-
centration units would allow the mass
rate to increase  in direct  proportion to
the volume of gas exhausted through the
control device. This is an advantage for
concentration units for grain elevators
since  a standard  with  concentration
units does not  discourage use  of large
volumes of ventilation air. As one might
surmize, adequate capture velocity at the
• collection hood is necessary for complete
capture of  the  particulate matter gen-
erated by the process. Another advantage
of concentration units is that the emis-
sion test provides all information neces-
sary for enforcement  (determination of
mass emissions per volume  of  gas dis-
charged through the  control  device).
Mass  standards,  however, are  usually
based on a unit of product or raw ma-
terial  to the process. They require an
accurate  determination of  both  mass
emissions and  product or raw material
weight. Product and raw material weight
are obtainable only from an operator and
are often difficult parameters to measure.
This is particularly true for grain eleva-
tor operations for the following reasons.
   1. The  weight  of  grain handled on
conveyor belts, legs, or cleaners is gen-
erally not measured.
   2. If more  than one process  is con-
trolled by  a single collector (i.e., head-
house filter), it may be  impossible to
determine the process weight during per-
formance testing. When a standard with
concentration units is applicable to each
process, compliance for any number of
processes  can  be determined  only  by
measuring the concentration from  the
control device.
  The average concentration of particu-
late matter emissions from all the grain
processes  tested, excluding  one which
had high emissions due to process irreg-
ularities, was 0.007 g/std. m' dry basis.
Most  of the individual test  results were
below  0.023 g/std. m' dry basis.  There-
fore,  EPA selected 0.023  g/std.  m'  dry
basis  as the emission limit  for the pro-
posed standards. To meet this  emission
limit, it  would  be  necessary for grain
operations to install and properly oper-
ate fabric filter control  systems rather
than  less  effective control systems such
as high efficiency cyclones.
  A zero percent opacity standard (based
on six-minute averages) is also proposed
for air pollution control devices. EPA ob-
served two fabric filter systems on grain
processes, and all of the individual read-
ings,  a total of 56 six-minute averages,
were  no  visible emissions. EPA believes
that the  proposed standard of zero per-
cent  opacity would ensure  the  proper
operation  and  maintenance of  the  air
pollution control device.
TRUCK AND RAILCAR UNLOADING  STATIONS

  The demonstrated  methods  for  con-
trolling  particulate  matter  emissions
from  truck and railcar unloading opera-
tions  include a collection hood in the re-
ceiving hopper ventilated to an air pol-
lution control  device  and  a protective
enclosure  around the facility to reduce
the interfering effect of winds. Generally,
enclosures or sheds are used to  protect
the grain  and workers from inclement
weather.  In some locations,  however,
where the weather is consistently dry,
unloading stations do not have sheds. In
developing the proposed standards, EPA
determined that a protective enclosure
is required to prevent wind from inter-
fering with the effectiveness of particu-
late  capture by the hopper ventilation
system. Three  alternatives  were evalu-
ated  by EPA concerning  protective en-
closures of the unloading station: (1) a
shed with two open ends, (2) a shed with
one open end, and (3)  a totally enclosed
shed.  A shed with two  open ends  was
determined to be least effective because
it allows  the  wind  -to  blow  directly
through and over the receiving  hopper.
A sned with one open  end and a totally
enclosed shed were found to  diminish the
effects of wind upon the ventilation
system.
  The totally  enclosed  shed has  been
demonstrated in railcar (hopper and box-
car)  unloading operations, where  the
two ends  of the shed are equipped with
quick-operating doors. However, all of
the truck  unloading facilities inspected
by EPA were designed so that the front
end of the truck extends out from the
open  end  of the shed. Some  reduction in
particulate-emissions could  be  achieved
by totally enclosing the truck unloading
operation; however, EPA knows of  no
elevators  that use this method. In order
to totally  enclose the operation, the shed
would have to be  increased  in  both
                               FSDEtlAi. QE6ISTSQ,  VOL 42, WO.

length and height because the front ends
of the trucks are raised considerably to
aJlow the grain to flow out the rear of the
truck. This would increase the cost of the
abed substantially. In addition, truck un-
loading operations  are located  at  all
small  country  elevators.  Greatly  in-
creased costs  would be incurred, espe-
cially At'small elevators, from the use
of a completely enclosed shed  on truck
unloading  operations.  Therefore,  EPA
has  concluded  that the  best  demon-
strated system  of  emission reduction
(considering costs) for truck unloading
stations is  a  shed with  one open  end
and  for rallcar  unloading stations it is
a totally enclosed shed.
  The system for railcar unloading would
Include a receiving hopper equipped with
baffles and ventilated at a rate of approxi-
mately 420 to 710 actual cubic meters per
minute (act mVmin) (ca. 15,000 to 25,000
cfm)  depending on the size of the fa-
cility. The  system for  truck unloading
would  Include   a   receiving   hopper
equipped with baffles and ventilated at a
rate  of approximately  340 act mVmin
(ca. 12,000 cfm).
  An emission standard of zero percent
opacity (six-minute average)  is proposed
for truck  unloading operations at grain
elevators. A total of 138 six-minute opac-
ity averages were  gathered by EPA. The
range for  these six-minute  averages is
no visible  emissions to one  percent. A
total of 120 six-minute  averages were no
visible emissions and 17 six-minute aver-
ages were zero percent opacity.  Based on
the available data, EPA concluded that
a  standard of zero percent opacity can
be achieved by the best  demonstrated:
system of emission reduction (consider-
ing costs) for truck unloading.
   The proposed standard for railcar un-
loading (boxcars and hopper cars)  is no
visible emissions. A total of two hours of
visible  emission/opacity  data   were
gathered by EPA on a boxcar unloading
operation. Every data point, taken at 15-
eecond Intervals,  indicated  no visible
emissions. Data to substantiate the pro-
posed standard were  not collected  for
hopper car unloading  operations. How-
ever, EPA has observed that unloading
of boxcars  is a dustier operation  than
unloading of hopper cars. Therefore, the
proposed standard applies to both hop-
per cars and boxcars. Based on the avail-
stole  data,  EPA  concluded that a stand-
ard   of  no visible emissions  can  be
achieved by the best system  of emission
reduction (considering  costs) for railcar
unloading.
  BARGE AND SHIP  UNLOADING STATIONS
   An equipment standard is proposed for
barge and ship  unloading  operations.
EPA observed the levels of visible emis-
sions at a barge unloading station. The
resulting data showed an extremely wide
range of visible emissions, with some six-
minute averages above 65 percent opac-
ity.   EPA  concluded  that  an  opacity
standard  could not be established  that
would ensure  the  installation of the best
system of  emission reduction (consider-
ing  costs)  because of this wide range of
visible emissions.
  All of the bucket elevators (legs)  ob-
served by EPA at barge and ship unload-
ing stations during the development pf
the proposed standards had various types
of enclosures and were ventilated. A fa-
cility with the leg enclosed from the top
(including the receiving hopper)  to the
center line of the bottom pulley appeared
to .perform with  the least emissions. This
facility was observed in operation  with
and without  the ventilation system in
operation.  Visible  emissions were  ob-
served to be significantly lower when the
ventilation system  was operating than
when it was not. EPA concluded that this
system represents tiie best demonstrated
system of emission reduction (consider-
ing costs)  and  proposes an equipment
standard based  on the  design of this
system.
     GRAIN HANDLING OPERATIONS
  Particulate  matter emissions  from
grain handling operations can  be mini-
mized through the use of totally enclosed
equipment, by handling the grain at a
slower rate, or by using ventilated hood-
ing systems designed to capture emis-
sions.
  Separate data were not  obtained  on
each item of grain handling equipment
included under  grain handling  opera-
tions. However, during observation of the
headhouse, the items included under this
affected facility were in operation. An ex-
terior conveyor  and  a headhouse  were
observed and all data recorded were no
visible emissions. A zero percent opacity
standard has been proposed instead of no
visible  emissions because  zero  percent
opacity (six-minute average) allows the
possibility of slight emissions from the
headhouse. EPA has concluded that the
best demonstrated- systems of  emission
reduction (considering costs) for grain
handling operations are totally enclosed
equipment or hooding systems ventilated
to air pollution control devices.
  TRUCK AND RAILCAR LOADING STATIONS
  During the development  of  the pro-
posed standards, EPA could not locate a
truck loading operation in the grain in-
dustry that used what was considered to
be  the best system of emission reduction
that could be applied. Therefore, other
industries such  as lime, and flour  and
grain processing were studied in an at-
tempt to find well-controlled truck load-
ing operations in these industries. EPA
located and  observed a  soybean  meal
truck loading operation. This operation is
well controlled;  however, it does not have
what is considered  to be the best system
of  emission reduction. Loading soybean
meal into trucks was determined  by EPA
to  be as dusty  an  operation as  loading
grain  into trucks;  therefore,  a direct
transfer of technology to grain  loading
operations is possible. The ten  percent
opacity limit is based on data gathered
at .this facility.  EPA believes that a bet-
ter control system can be designed than
the one observed;  however, this is the
best system that has been demonstrated
for truck loading operations which are
very similar to grain loading operations.
EPA has concluded that the best system
of emission reduction (considering costs)
for truck loading stations is a shed with
one open  end,  equipped with a loading
spout with a canvas sleeve and a hood-
ing system ventilated at a rate of about
260 to  350 .act mVmin  (ca. 10,000 to
12J250 cfm).
  Particulate  matter emissions which
result  from the loading of grain into
hopper  cars is  controlled in the grain
industry by a hooding system, ventilated
to an air pollution control device, located
at the  end  of  the  loading  spout. The
loading operation is usually  enclosed in
a shed with two open ends. This control
method is the only  effective  demon-
strated  particulate  control system used
for loading grain into hopper cars. The
type of hooding and the ventilation rates
are the only variables.  Several hopper
car grain loading systems were studied
by EPA by reviewing the manufacturer's
.designs of the systems and through com-
munications with grain  elevator opera-
tors and plant engineers. EPA gathered
data from the  operation which was de-
termined to be  the most effective system.
The individual 15-second opacity  data
collected were  all zero percent opacity
or no  visible  emissions. There was  no
appreciable wind during this observation
period.  Therefore, EPA was proposed a
zero percent opacity limit to allow for
possible slight particulate emissions dur-
ing other than  ideal conditions. EPA has
concluded that the best system  of emis-
sion reduction  (considering costs)  for
railroad hopper car  loading stations  is
a shed with two open ends, and a hood-
ing system located next to  the loading
spout which is ventilated at a rate of
about 280 act  m'/min (ca. 10,000 cfm).
  The grain industry has essentially only
one demonstrated   particulate control
system  for loading boxcars. The  entire
operation is usually  enclosed in a shed
with two open ends. EPA took opacity
observations on the best controlled fa-
cility which was found. The data ranged
from three to  five percent opacity. The
operation observed,  however, was  not
considered to  employ the  best  control
technology that could be applied. The
.facility could have  been maintained in
better condition and higher ventilation
rates could have been used.
   Hopper car  loading and boxcar load-
ing operations  are similar and best tech-
nology  requires  a  shed with two open
ends and a hooded loading spout venti-
lated to an air pollution control  device
on  both  facilities.  The  grain  Sows
through a loading spout and is deposited
in a receiving vessel (the railcar) at each
facility.  Fugitive   particulate  matter
emissions are  also  generated in a simi-
lar manner. The stream  of grain  and
induced air flowing into the railcar dis-
turbs and displaces the air in the railcar.
Also, when the gram impacts against the
receiving vessel, turbulence is created in
the surrounding air. Particulate matter
can be entrained  in the turbulent  air
currents and flow out of the railcar with
the displaced  air.  EPA IE proposing  a
zero percent opacity standard on boxcar
loading stations based on a transfer  of

 technology , from hopper  car loading
 stations.
   EPA has concluded that the best sys-
 tem of emission reduction  (considering
 costs) for railroad boxcar' loading sta-
 tions is  a shed with two open ends. A
 loading spout enclosed by a small build-
 ing-like   structure  which  extends  to
 within 150 mm (ca. 6 inches) of the side
 of the boxcar and hinged doors about 200
 mm (ca.  8 inches) wide, equipped with
 rubber flaps, which seal the sides of the
 enclosure to the boxcar are part of this
 best  control system. This  building-like
 structure is ventilated at a rate of about
 280 act m'/min (ca. 10,000 cfm).
   BARGE  AND SHIP LOADING STATIONS

   EPA considered two  systems for con-
 trolling   particulate  matter   emissions
 from barge and ship loading. The first
 consists  of a telescoping loading  spout
 that  is adjusted to the elevation of the.
 grain surface   as   loading   proceeds.
 Ventilation is applied at the end of the
 spout and then vented  to a fabric filter.
 Two  variations of this system were ob-
 served by EPA. The second system con-
 sidered was to cover the hold with canvas
 or plastic sheeting except where the load-
 ing spout enters. However, no  system of
 this type was observed in operation. EPA
 believes both control systems can achieve
 the proposed opacity standards.
   Data were gathered from a ship load-
 tag operation employing the first control
 approach mentioned. These data revealed
 that  during topping-off  operations, re-
 corded opacities were greater than  dur-
 ing general  loading  operations.  EPA,
 therefore, has proposed a two-level opac-
 ity standard for barge  and ship loading
 operations. General  loading  operations
 have a  ten percent opacity  limit and
 topping-off operations have a fifteen per-
 cent opacity limit.
   EPA has no data on loading grain into
 barges. However, J2PA has visited barge
 loading operations and believes the  op-
 erations   to be  similar to ship loading
 operations;  therefore,   the   proposed
 standards apply to barge loading as well
 as to ship loading.
      TESTING AND  RECORDKEEPING
   Under  the  proposed standards,  per-
 formance  tests for particulate matter
 emissions would be required for air pollu-
 tion control devices on all affected facili-
 ties. Particulate matter would be meas-
 ured by Reference Methods 1 through 5
 and 17. EPA  Reference Method 17 was
 proposed  in the  Standards  of  Perform-
 ance for  Kraft Pulp Mills on  Septem-
 ber 24,1976 (41 FR 42012).
   The definition of  particulate matter
 has been revised to allow measurement
 by the reference method specified under
 each applicable subpart.  This definition
 has been  revised because Method 17 has
•been proposed as a reference method for
 particulate matter.
   Records of performance testing meas-
 urements would  have to be maintained
 and retained for at least two years fol-
 lowing the date of the measurements by
 owners or operators subject to the pro-
 posed regulations.  This requirement is
included under section  60.7 (d)  of  the
regulations.
         PUBLIC PARTICIPATION
  As prescribed by section 111, this pro-
posal of standards of performance  has
been  preceded by  the  Administrator's
determination that grain elevators con-
tribute  significantly  to air  pollution
which causes  or contributes to the en-
dangerment of public  health or welfare
and by his publication of this determina-
tion in this issue of the FEDERAL REGISTER.
In accordance with section 117 of the Act,
publication of these proposed standards
was preceded by consultation with appro-
priate advisory committees, independent
experts,  and  Federal  departments and
agencies.
  Interested persons may participate in
this rulemaking by submitting comments
(in triplicate)  to the Emission Standards
and Engineering Division, U.S. Environ-
mental Protection Agency, Research Tri-
angle Park, North Carolina 27711,  At-
tention: Mr. Don R. Goodwin. The Ad-
ministrator will welcome comments  on
all  aspects of the  proposed regulations,
including the designation of graip eleva-
tors as a significant contributor to air
pollution which causes or contributes to
the endangerment of public  health or
welfare, economic and technological  is-
sues,  and on the proposed test methods.
  Comments are invited specifically  on
the proposed  standard  for railcar  un-
loading stations and its effect on the un-
loading of  unit trains. A number of in-
terested parties have expressed concern
that  the uncoupling of  railcars, which
would  be  required when  operating  a
totally  enclosed unloading shed would
have  an adverse economic impact. Com-
ments on this  issue should contain speci-
fic information and data pertinent to an
evaluation  of  the magnitude of this im-
pact and its severity.
  In  addition, EPA  is interested in re-
ceiving comments on the selection of the.
best system of emission  reduction,  con-
sidering costs, for grain dryers. The com-
ments should  address the factors  EPA
used in evaluating the alternative emis-
sion control systems.
  All relevant comments-received on or
before March  14, 1977 will be considered.
Comments  received will be available for
public inspection and copying at the Pub-
lic Information Reference  Unit, Room
2922 (EPA  Library), 401  M Street, S.W.,
Washington, D.C. 20460.
  Background information on  these pro-
posed standards of performance has been
published  in  a document "Standards
Support and  Environmental  Impact
Statement, Volume  1: Proposed Standr
ards of Performance for the Grain Eleva-
tor Industry."  This  report presents the
factors considered in the development of
the proposed  standards, including  al-
ternative emission control systems, emis-
sion  test data, environmental  impact,
costs,  and  economic  considerations.

 Standards of Performance for New Station-
 ary Sources;  Extension of Comment Period
   On January  13, 1977,  the  Environ-
 mental Protection Agency (EPA)  pub-
 lished a notice  of proposed rulemaking
 under section 111 of the Clean Air Act,
 as amended  (42 PR 2842). The proposed
 regulation would establish standards of
 performance for new, modified or recon-
 structed grain elevators. The  comment
 period for this proposed regulation ends
 March 14. 1977.
  EPA has been requested by the Gov-
ernor of Kansas to extend the comment
period 60 days in order to allow the Kan-
sas  Secretary of Health  and Environ-
ment, representatives of the State's grain
industry, and  other interested parties
additional time to compile, assemble and
submft, comments. Since it appears that
a number of persons  would like  addi-
tional  time  to  submit comments,  the
comment period is being extended  60
days for all parties who may  wish to
participate in this rulemaking. All com-
ments postmarked by May 14, 1977, will
 be considered and should be submitted
 (in triplicate) to the Emission Standards
 and Engineering Division (MD-13), U.S.
