                             INTRODUCTION
     This document has been produced in compliance with Section 110(h)(1)
of the Clean Air Act Amendments of 1977.  The Federally enforceable
regulations contained in the State Implementation Plans (SIPs) have been
compiled for all 56 States and territories (with the exception of the
Northern Mariana Islands).  They consist of both the Federally approved
State and/or local air quality regulations as indicated in the Federal
Register and the Federally promulgated regulations for the State, as
indicated in the Federal Register.  Regulations which fall into one of
the above categories as of January 1, 1978, have been incorporated.  As
mandated by Congress, this document will be updated annually.  State
and/or local air quality regulations which have not been Federally
approved as of January 1, 1978, are not included here; omission of these
regulations from this document in no way affects the ability of the
respective Federal, State, or local agencies to enforce such regulations.

     There have been recent changes in the Federal enforceability of
parking management regulations and indirect source regulations.  The
October, 1977, appropriation bill for EPA prohibited Federal enforcement
of parking management regulations in the absence of specific Federal
authorizing legislation.  Federally promulgated parking management
regulations have, therefore, been suspended indefinitely.   Pursuant to
the 1977 Clean Air Act Amendments, indirect source regulations may not
be required for the approval of a given SIP.   Consequently, any State
adopted indirect source regulations may be suspended or revoked; State
adopted indirect source regulations contained in an applicable SIP
are Federally enforceable.  More importantly, EPA may only promulgate
indirect source review regulations which are specific to Federally
funded, operated, or owned facilities or projects.  Therefore, the
Federally promulgated indirect source regulations appearing in this
document are not enforceable by EPA except as they relate to Federal
facilities.

     Since State air quality regulations vary widely in their organization,
content, and language, a standardized subject index is utilized in this
document.  Index listings consist of both contaminant and activity oriented
categories to facilitate usage.  For example, for regulations which apply
to copper smelters, one might look under sulfur compounds (50.2), particu-
late matter process weight (50.1.1), or copper smelters (51.15).  Federal
regulations pertaining to a given State immediately follow the approved
State and local regulations.

     Additionally, a summary sheet of the information included in each
comprehensive document is presented prior to the regulatory text to
allow one to quickly assess the contents of the document.   Specifically,
the summary sheets contain the date of submittal to EPA of each revision
                                     in

-------
to the SIP and the date of the Federal Register in which the revision
was either approved or disapproved by EPA.  Finally, a brief description
or reference of the regulation which was submitted is also included.

     This document is not intended to provide a tool for determining
the enforceability of any given regulation.  As stated above, it is
intended to provide a comprehensive compilation of those regulations
which are incorporated directly or by reference into Title 40, Part 52,
of the Code of Federal Regulations.  Consequently, the exclusion of a
Federally approved regulation from this document does not diminish the
enforceability of the regulation.  Similarly, the inclusion of a given
regulation (for example, regulations governing pollutants, such as odors,
for which there is no national ambient air quality standards) in this
document does not, in itself, render the regulation enforceable.

               MATTER FROM BECOMING AIR-BORNE,  AIR CONTAMINANT  DETECTORS AND
               EMISSION OF AIR CONTAMINANTS DETRIMENTAL  TO  PERSON  OR PROPERTY


(50.1.2)    1.   Visible Emissions

           No  person shall discharge into the atmosphere from any  single source  any
           air contaminant for a period or periods aggregating  more  than three
           minutes in any one hour which is:
               (a)  As dark as or darker than that shade designated  No. 1  on  the
                    Ringelmann Chart, published by the United States Bureau of
                    Mines, or the same shade designation on  a photographic copy
                    of the Ringelmann Chart reduced to one-eighteenth of the
                    size of the original, for convenient use in the  field.
               (b)  Of such opacity as to obscure an observer's view to a  degree
                    equal to or greater than does an air contaminant described
                    in Subsection (a) of this rule.

           2.   Handfiring of Soft Coal

           It shall be unlawful to use, to import, sell, offer  for sale, expose  for
           sale, exchange, deliver or transport for use or  consumption in  a hand
           fired installation in the State of Rhode Island  any  solid fuel  other  than
           coke or anthracite coal.  Anthracite coal shall  be defined by the  ASTM
           Standards of 1938.  This ruling does not apply to indoor  fireplaces.
           Any coal having a dry basis volatile content greater than that  of
           anthracite coal may be imported, sold, offered for sale,  exposed for  sale,
           exchanged, delivered or transported, used or consumed in  the State of
           Rhode Island only in approved mechanical fuel burning equipment.   Any
           solid fuel containing volatile matter greater than that of anthracited
           coal on a dry basis shall, within the discretion of  the Director,  be
           acceptable under the terms of these rules and regulations provided that
           it meets the same standard in regard to smoke production  as does  anthracite
           coal.  In order to ascertain whether or not such standards are  met,
           anyone applying for the use of such solid fuel shall submit (1) Complete
           plans and specifications of such  process to the Director, and  from time
           to time any additional information he may reasonably require  regarding
           the product.   (2)  An adequate supply of the finished product must be
           made available to the Director to conduct whatever tests  he deems
           necessary to establish its value as a smokeless  solid fuel. Any  person,
           firm or corporation whose product is submitted to such tests must  pay in
           advance all expenses necessary thereto.

(50.1)     3.   Particulate Emissions

           No person shall discharge in any one hour, from any  source, particualte
           emissions in a total amount in excess of that shown  in the following
           table (see next page) opposite the applicable process weight.   In
           entering the table, the process weight per hour used is the total  weight
           of all materials introduced into any specific process which may cause
           any emissions  into the atmosphere except liquid and  gaseous fuels  and
           combustion air.  "The Process Weight Per Hour" will  be determined  by
                                               -1-

                      8.1.3   "High  Sulfur  Fuel" means a  fuel containing  more  than 0.55
                             pounds  of  sulfur per million BTU  heat release potential.
                      8.1.4   "Stack" or "chimney" means  a flue,  conduit  or opening  to
                             provide for the emission of particulates  or gases  into  the
                             open air.
                      8.1.5   "Approved  stack-gas cleaning process" means a process,  ap-
                             proved  by  the director,  which  removes sulfur  dioxide from

                 8.2   On and  after  October 1, 1971  unless the  director declares  in  writ-
                      ing that a shortage  of low sulfur  fuel exists, no  person,  except
                      as provided in Sections 8.3 and 8.4,  shall store for sale, offer
                      for sale, sell or deliver for use  in  Rhode Island, and  no  person
                      shall use or  store high sulfur fuel provided, however,  that any
                      person  who on  the date of promulgation of  these  regulations has  in
                      his possession within  this state a supply  of high  sulfur  fuel  may
                      sell or deliver for  use or use the same  within this  state  at  any
                      time prior to  March  1, 1972.

                 8.3   The director  may  approve  the  use of high sulfur  fuel when  combined
                      with an approved  stack-gas cleaning process, provided the  sulfur
                      compound emissions (expressed as sulfur  dioxide) from the  stack  or
                      chimney do not exceed  1.1 pounds per  million BTU gross  heat input,
                      and the person using such process  gives  evidence satisfactory to
                      the director  that the  emissions do not exceed the  requirements of
                      this Section.

                 10.1   Episode Criteria
                       Conditions justifying the proclamation  of an  air  pollution  alert,
                       air pollution warning or air pollution  emergency  shall  be deemed
                       to exist whenever the director determines that  the  accumulation
                       of air pollutants in any place is  attaining or  has  attained
                       levels which could,  if such levels are  sustained  or exceeded,
                       lead to a substantial threat to the health of persons.   In  making
                       this determination,  the director will be guided by  the  following
                       criteria:

                            (a)  "Air Pollution Forecast":  An internal  watch  by the
                                 Division of Air Pollution Control shall be actuated  by
                                 a National Weather Service advisory that  Atmospheric

                                 local  forecast of stagnant atmospheric  condition.
                            (b)  "Air Pollution Alert":  The Alert level is that concen-
                                 tration of pollutants at which first  stage control
                                 actions is to begin.  An Alert will be  declared when
                                 any one of the following levels is  reached at any
                                 monitoring site:

                                 S02 —500 ug/m3 (0.11 ppm), 24-hour average.

                                 Particulate-- 3.0 COHs,  24- hour average.

                                 S02 and Particulate Combined  — Product of SO? (ppm)

                                 N02 — H30 uq/m3 0.6 ppm), 1-hour  average, 282  ug/m
                                 (o.l5  ppm), 24-hour average.

                                 and meteorological conditions are  such  the pollutant
                                 concentrations can be expected to  remain  at the  above
                                 levels for twelve (12) or more hours  or increase  unless
                                 control actions are taken.
                            (c)  "Air Pollution Warning":  The Warning level indicates
                                 that air quality is continuing to  degrade and that
                                 additional control actions are necessary.  A warning
                                 will be declared when any one of the  following levels
                                 is reached at any monitoring site:

                (0.3 ppm), 24-hour average

                and meteorological  conditions are  such  that pollutant
                concentrations can be expected to  remain at the above
                levels for twelve (12)  or more hours  or  increase  unless
                control actions are taken.

           (d)   "Air Pollution Emergency":  The  Emergency level indicates
                that air quality is continuing to  degrade to a  level that
                should never be reached and that the  most stringent
                control actions are necessary.   An emergency will  be
                declared when any one of  the  following  levels is  reached
                at any monitoring site:
                                3
                S02 — 1309 ug/m  (0.5  ppm),  24-hour  average.

                CO —  46 mg/m  (40 ppm),  8-hour  average.

                Oxidant  (03) --  1200  ug/m  (0.6  ppm),  1-hour  average.

                                3                                   3
                N02 — 3000 ug/m  (1.6  ppm),  1-hour average, 750  ug/m
                (0.4 ppm), 24-hour average.

                and meteorological conditons  are such that this
                condition  can be expected to  continue for twelve  (12)
                or more hours.

           (e)   "Termination":  Once declared,  any status reached by
                application of these criteria will remain in effect
                until  the  criteria for  that level  are no longer met.
                At such time, the next  lower  status will be assumed.

10.2  Emission  Reduction Plans

                 volumes for one, eight, and 24-hour time periods
                 expected within 10 years of date of expected comple-
                 tion.

            (b)  An estimate of vehicle speeds for average and maxi-
                 mum traffic volume conditions and the vehicle capac-
                 ity of the highway project.

            (c)  A map showing the location of the highway project,
                 including the location of buildings along the right-
                 of-way .

            (d)  A description of the general features of the high-
                 way project and associated right-of-way, including
                 the approximate height of buildings adjacent to the
                 highway.

            (e)  Any additional information or documentation that the
                 Administrator deems necessary to determine the air
                 quality impact of the indirect source,  including the
                 submission of measured air quality data at the pro-
                 posed  site prior to construction or modification.

     (iv)    For  indirect sources other than airports and those high-
            way  projects subject to the provisions of  paragraph  (b)
            (6)  (iii) of this section, the air quality monitoring re-
            quirements  of  paragraph (b)  (3)  (i) (i) of this section
            shall be limited to carbon monoxide, and shall be con-
            ducted for  a period of not more than 14 days.

(4)   (i)     For  indirect sources other than highway projects and air-
            ports, the  Administrator shall not approve an application
            to construct or modify if he  determines that the indirect
            source will:

             (a)  Cause  a violation of the control strategy of any
                 applicable state  implementation plan;  or

             (b)  Cause  or  exacerbate a violation of the  national stan-
                 dards  for carbon monoxide in any region or portion
                 thereof.

     (ii)    The  Administrator  shall make  the determination pursuant
            to paragraph  (b)  (4)  (i)  (b)  of  this section by evaluat-
             ing  the  anticipated  concentration of carbon  monoxide at
             reasonable  receptor  or exposure  sites which  will be  af-
             fected by  the  mobile  source  activity expected to be  at-
             tracted  by  the indirect source.  Such determination  may
             be made  by  using  traffic  flow characteristic guidelines
                              -33-

             Administrator shall  not approve an  application to  con-
             struct  or  modify  if  he determines that the indirect  source
             will:

             (a)  Cause a  violation of the control strategy of  any ap-
                  plicable state  implementation  plan;  or

             (b)  Cause or exacerbate a violation of the  national  stan-
                  dards for carbon monoxide in any region or portion
                  thereof.

     (ii)     The determination pursuant to paragraph (b)  (6)  (i)   (b)
             of this section shall  be made by  evaluating  the anticipa-
             ted concentration of carbon monoxide at reasonable  re-
             ceptor or exposure sites which will be affected by the
             mobile  source activity expected on the highway for the ten
             year period following the expected date of completion ac-
             cording to the procedures specified in paragraph  (b) (4)
             (ii) of this  section.

     (iii)   For new highway projects  subject to this  paragraph with
             an anticipated average daily traffic volume of 50,000 or
             more vehicles within ten years of construction, or mod-
             ifications to highway projects subject to this paragraph
             which will increase average daily traffic volume  by  25,000
                              -34-

             or more  vehicles  within  ten years  after modification,  the
             Administrator's decision on the  approval  or disapproval
             of an  application shall  be based on  the considerations  to
             be published as an Appendix to this  Part  in addition  to
             the requirements  of paragraph  (b)  (6)  (i)  of  this  section.

(7)   The determination of the  air quality  impact  of a  proposed  indi-
     rect source "at  reasonable receptor or exposure sites", shall mean
     such locations where people might reasonably be exposed for time
     periods consistent with the national  ambient air  quality standards
     for the pollutants specified for analysis  pursuant to this para-
     graph.

(8)   (i)     Within 20 days after receipt  of  an application or  addition
             thereto, the Administrator shall advise the owner  or opera-
             tor of any deficiency in the  information  submitted in sup-
             port of  the application.  In  the event of such a defi-
             ciency,  the date  of receipt of the application for the
             purpose  of paragraph (b) (8)  (ii)  of this section  shall
             be the date on which all required  information is received

                  preliminary determination,  and  a copy or summary of
                  other materials, if any, considered  by the  Adminis-
                  trator in making his preliminary determination;  and

             (c)  Notify the public, by prominent advertisement in a
                  newspaper of general circulation in  each region in
                  which the proposed indirect source would be con-
                  structed, of the opportunity for written public com-
                  ment on the  information submitted by the owner or
                  operator and the Administrator's preliminary deter-
                  mination on  the approvability of the indirect source.

     (iii)   A  copy of the notice required pursuant to this subpara-
             graph shall be sent to  the applicant and to officials
             and agencies having cognizance over the location where
             the indirect source will be situated, as  follows:   State
             and local air pollution control  agencies, the chief exec-
             utive of the city and county;   any comprehensive  regional
                              -35-

             land  use  planning  agency;  and  for highways, any  local
             board or  committee charged with responsibility  for activ-
             ities in  the  conduct of  the  urban transportation  planning
             process  (3-C  process)  pursuant  to 23 U.S.C. 134.

     (iv)     Public comments  submitted in writing within 30  days after
             the date  such information is made available shall be con-
             sidered by  the Administrator in making his final  decision
             on the application.  No  later than 10 days after  the close
             of the public comment  period, the applicant may submit a
             written response to any  comments submitted by the public.
             The Administrator  shall  consider the applicant's  response
             in making his final decision.   All comments shall be made
             available for public inspection in at least one location
             in the region in which the indirect source would  be lo-
             cated.

     (v)      The Administrator  shall  take final action on an applica-
             tion  within 30 days after the close of the public comment
             period.   The  Administrator shall notify  the applicant in
             writing of  his approval, conditional approval,  or denial
             of the application, and  shall set forth  his reasons for
             conditional approval or  denial. Such notification shall
             be made available  for  public inspection  in at least one
             location  in the  region in which the indirect source would
             be located.

     (vi)     The Administrator  may  extend each of the time periods
             specified in  paragraphs  (b)  (8) (ii), (iv), or  (v) of
             this  section  by  no more  than 30 days, or such other peri-
             od as agreed  to  by the applicant and the Administrator.

(9)   (i)      Whenever  an indirect source  as  proposed  by an owner or
             operator's  application would not be permitted to  be con-
             structed  for  failure to  meet the tests set forth  pursuant
             to paragraphs (b)  (4)  (i),  (b)  (5)  (i),  or  (b)  (6)  (i)
             and  (iii) of  this  section, the  Administrator may  impose
             reasonable  conditions  on an  approval related to the air
             quality aspects  of the proposed indirect source so that
             such  source,  if  constructed  or  modified  in accordance
             with  such conditions,  could  meet the tests set  forth
             pursuant  to paragraphs (b)  (4)  (i),  (b)  (5)  (i),  or  (b)
             (6)  (i)  and (iii)  of this section.  Such conditions may
             include,  but  not be limited  to:

             (a)   Binding  commitments to  roadway improvements  or ad-
                  ditional mass transit  facilities to serve  the  in-
                  direct source secured  by  the  owner  or operator  from
                  governmental  agencies having  jurisdiction  thereof;

             (b)   Binding  commitments by  the owner or operator to
                  specific programs for mass transit  incentives  for
                  employees and patrons of  the  source;   and
                               -36-

-------
              (c)   Binding  commitments by  the owner or operator to con-
                   struct,  modify,  or operate the  indirect source in
                   such  a manner  as may  be necessary  to achieve the
                   traffic  flow characteristics  published by the Envi-
                   ronmental  Protection  Agency pursuant to paragraph
                   (b)  (4)  (ii) of  this  section.

      (ii)     The  Administrator may specify that any  items of  informa-
              tion provided in an application for  approval related to
              the  operation of an indirect source  which may affect the
              source's  air  quality  impact  shall  be considered  permit
              conditions.

(10)   Notwithstanding the provisions  relating to modified  indirect
      sources contained in  paragraph  (b) (2) of  this  section,  the Ad-
      ministrator  may condition any approval by  reducing the extent to
      which the indirect source may be  further modified without resub-
      mission for  approval  under  this  paragraph.

(11)   Any owner or operator who fails  to construct an indirect source
      in accordance with the application as approved  by the Administra-
      tor;   any owner or operator who  fails to construct and operate an
      indirect source in accordance with conditions  imposed by the Ad-
      ministrator  under paragraph (b)  (9)  of this  section;  any owner
      or operator  who modifies  an indirect source  in  violation of con-
      ditions imposed by the Administrator under paragraph  (b) (10) of
      this  section;  or any owner or  operator of an  indirect source
      subject to this paragraph who commences construction or  modifi-
      cation thereof after  December 31,  1974, without applying for  and
      receiving approval hereunder, shall  be subject  to the penalties
      specified under section 113 of  the Act and shall be  considered  in
      violation of an emission  standard or limitation under section  304
      of the Act.   Subsequent modification to  an approved  indirect
      source may be made without  applying for  permission  pursuant  to
      this paragraph only where such  modification  would not violate  any
      condition imposed pursuant  to paragraphs  (b) (9)  and (10) of  this
      section and  would not be subject to the modification criteria  set
      forth in paragraph (b) (2)  of this section.

(12)  Approval to  construct or modify shall become invalid if  construc-
      tion or modification  is not commenced within 24 months  after  re-
      ceipt of such approval.  The Administrator may extend  such  time
      period upon satisfactory showing that an  extension  is  justified.
      The applicant may apply for such an extension  at the time  of ini-
      tial  application or at any  time thereafter.

(13)  Approval to construct or modify shall not  relieve  any  owner or
      operator of the responsibility  to comply  with  the  control  strategy
      and all local, State and Federal  regulations which  are  part of the
      applicable State implementation plan.
                                -37-

(14)   Where the Administrator delegates  the responsibility for imple-
      menting the procedures for conducting indirect source review pur-
      suant to this paragraph to any agency, other than a regional  of-
      fice of the Environmental  Protection Agency, the following pro-
      visions shall apply:

      (i)     Where the agency designated is not an air pollution
              control  agency, such agency shall  consult the appropri-
              ate State or local air pollution control agency prior to
              making any determination required by paragraphs (b) (4),
              (5), or (6) of this section.  Similarly, where the agency
              designated does not have continuing responsibilities for
              land use planning, such agency shall consult with the
              appropriate State or local  land use and transportation
              planning agency prior to making any determination re-
              quired by paragraph (b) (9) of this section.

      (ii)    The Administrator of the Environmental Protection Agency
              shall conduct the indirect source review pursuant to
              this paragraph for any indirect source owned or operated
              by the United States Government.

      (iii)   A copy of the notice required pursuant to paragraph (b)
              (8) (ii) (c)  of this section shall be sent to the Admin-
              istrator through the appropriate Regional Office.

(15)   In any area in which a "management of parking supply" regulation
      which has been promulgated by the Administrator is in effect, in-
      direct sources which are subject to review under the terms of such
      a regulation shall not be required to seek review under this para-
      graph but instead shall be required to seek review pursuant to
      such management of parking supply regulation.  For purposes of
      this paragraph, a "management of parking supply" regulation shall
      be any regulation promulgated by the Administrator as part of a
      transportation control plan pursuant to the Clean Air Act which
      requires that any new or modified facility containing a given num-
      ber of parking spaces shall receive a permit or other prior approv-
      al, issuance of which is to be conditioned on air quality consid-
      erations.

(16)   Notwithstanding any of the foregoing provisions to the contrary,
      the operation of this paragraph is hereby suspended pending fur-
      ther notice.  No facility which commences construction prior to
      the expiration of the sixth month after the operation of this para-
      graph is reinstated (as to that type of facility) shall be subject
      to this paragraph.

                     equivalent areas that pervasively exceeded any national ambient
                     air quality standards during 1974 for sulfur dioxide or particu-
                     late matter and then  only with respect to such pollutants.
                     States may notify the Administrator at any time of those areas
                     which  exceeded the national standards during 1974 and therefore
                     are exempt from the requirements of this  paragraph.

     (ii)    For purposes of this paragraph, areas designated as  Class
             III shall be limited to concentrations~ of "particulate
             matter and sulfur dioxide no greater than the national
             ambient air quality standards.

     (iii)   The air quality impact of sources granted approval  to
             construct or modify prior to January 1,  1975 (pursuant to
             the approved new source review procedures in the plan)
             but not yet operating prior to January 1, 1975,  shall not
             be counted against the air quality increments specified
             in paragraph (c) (2) (i) of this section.

(3)  (i)     All areas are designated Class II as of the effective
             date of this paragraph.  Redesignation may be proposed by
             the respective States, Federal  Land Manager, or Indian
             Governing Bodies, as provided below, subject to approval
             by the Administrator.

     (ii)    The State may submit to the Administrator a proposal to
             redesignate areas of the State Class I,  Class II, or
             Class III, provided that:

             (a)  At least one public hearing is held in or near the
                  area affected and this public hearing is held in
                  accordance with procedures established in 51.4 of
                  this chapter, and

             (b)  Other States, Indian Governing Bodies, and Federal
                  Land Managers whose lands may be affected by the
                  proposed redesignation are notified at least 30 days
                  prior to the public hearing, and
                               -40-

-------
        (c)  A discussion of the reasons for the proposed redes-
            ignation  is available for public inspection at least
            30 days prior to the hearing and the notice announc-
            ing the hearing contains appropriate notification of
            the availability of such discussion, and

        (d)  The proposed redesignation  is based on the record of
            the State's hearing, which  must reflect the basis
            for the proposed redesignation, including consider-
            ation  of  (1)  growth anticipated in the area,  (2)
            the social, environmental,  and economic effects of
            such  redesignation upon the area being proposed for
            redesignation and upon other areas and States, and
            (3)   any  impacts of such proposed redesignation upon
            regional  or national interests.

        (e)  The redesignation is proposed after consultation
            with  the  elected leadership of local and other sub-
            state general purpose governments in the area cov-
            ered  by the proposed redesignation.

(iii)    Except  as  provided in paragraph  (c) (3)  (iv) of this
        section, a State in which lands  owned by the Federal Gov-
        ernment are located may submit to the Administrator a
        proposal to redesignate such lands Class  I, Class  II,  or
        Class  III  in accordance with subdivision  (ii) of this
        subparagraph provided that:

        (a)  The redesignation  is consistent with adjacent State
            and privately owned  land, and

        (b)  Such  redesignation  is  proposed after consultation
            with  the  Federal Land  Manager.

(iv)    Notwithstanding subdivision  (iii) of  this subparagraph,
        the Federal Land Manager  may  submit to  the  Administrator
        a proposal to  redesignate any  Federal  lands to  a more
        restrictive designation  than would otherwise be  applic-
        able provided  that:

        (a)  The Federal  Land Manager follows  procedures equiv-
             alent to  those  required  of  States  under  paragraph
             (c) (3)  (ii)  and,

        (b)   Such  redesignation  is  proposed  after consultation
            with  the  State(s)  in which  the  Federal  Land is  lo-
             cated or  which  border  the Federal  Land.

(v)     Nothing in this section  is  intended  to convey  authority
        to the States  over Indian Reservations  where  States  havs
        not assumed such authority  under other laws nor is it
        intended to deny jurisdiction which  States  have assumed
                          -41-

-------
        under other laws.   Where a State has  not assumed juris-
        diction over an Indian  Reservation  the appropriate In-
        dian Governing Body may submit to the Administrator a
        proposal  to redesignate areas  Class I, Class  II, or
        Class III,  provided that:

        (a)   The Indian Governing  Body follows procedures equiv-
             alent  to those required of States under  paragraph
             (c)  (3) (ii)  and,

        (b)   Such redesignation is proposed after consultation
             with the State(s)  in  which the Indian Reservation
             is located or which border the Indian Reservation
             and, for those lands  held in trust, with the approv-
             al of  the Secretary of the Interior.

(vi)     The  Administrator  shall approve, within 90 days, any re-
        designation proposed pursuant  to this subparagraph as
        follows:

        (a)   Any redesignation  proposed pursuant to subdivisions
             (ii) and (iii) of  this subparagraph shall  be approv-
             ed unless the Administrator determines (1)  that the
             requirements  of subdivisions (ii) and (iii) of this
             subparagraph  have  not been complied with,  (2)  that
             the State has arbitrarily and capriciously disre-
             garded relevant considerations set forth in sub-
             paragraph (3) (ii) (d) of this paragraph,  or (3)
             that the State has not requested and received dele-
             gation of responsibility  for carrying out the new .
             source review requirements of paragraphs (d) and (e)
             of this section.

        (b)   Any redesignation  proposed pursuant to subdivision
             (iv) of this  subparagraph shall  be approved unless
             he determines (1)   that the requirements of subdivi-
             sion (iv) of  this  subparagraph have not  been complied
             with,  or (2)   that the Federal Land Manager has arbi-
             trarily and capriciously  disregarded relevant con-
             siderations set forth in  subparagraph (3)  (ii) (d)  of
             this paragraph.

        (c)   Any redesignation  submitted pursuant to  subdivision
             (v) of this subparagraph  shall be approved unless he
             determines (1)  that the  requirements of subdivision
             (v) of this subparagraph  have not been complied with,
             or (2)  that  the Indian Governing Body has arbitrar-
             ily and capriciously disregarded relevant consider-
             ations set forth in subparagraph (3) (ii) (d) of this
             paragraph.
                          -42-

-------
                 (d)  Any redesignation proposed pursuant to this para-
                      graph shall be approved only after the Administrator
                      has solicited written comments from affected Federal
                      agencies and Indian Governing Bodies and from the
                      public on the proposal.

                 (e)  Any proposed redesignation protested to the propos-
                      ing State, Indian Governing Body, or Federal Land
                      Manager and to the Administrator by another State or
                      Indian Governing Body because of the effects upon
                      such protesting State or Indian Reservation shall be
                      approved by the Administrator only if he determines
                      that in his judgment the redesignation appropriately
                      balances considerations of growth anticipated in the
                      area proposed to be redesignated;  the social, envi-
                      ronmental and economic effects of such redesignation
                      upon the area being redesignated and upon other areas
                      and States;  and any impacts upon regional or nation-
                      al interests.

                 (f)  The requirements of paragraph (c) (3) (vi) (a) (3)
                      that a State request and receive delegation of the
                      new source review requirements of this section as a
                      condition to approval of a proposed redesignation,
                      shall include as a minimum receiving the administra-
                      tive and technical functions of the new source re-
                      view.  The Administrator will carry out any required
                      enforcement action in cases where the State does not
                      have adequate legal authority to initiate such ac-
                      tions.  The Administrator may waive the requirements
                      of paragraph (c) (3) (vi) (a) (3) if the State Attor-
                      ney-General has determined that the State cannot ac-
                      cept delegation of the administrative/technical func-
                      tions.

          (vii)    If the  Administrator disapproves any proposed area desig-
                 nation  under this subparagraph, the State, Federal Land
                 Manager or  Indian Governing Body, as appropriate, may re-
                 submit  the proposal after correcting the deficiencies
                 noted by the Administrator or reconsidering any area des-
                  ignation determined by the Administrator to be  arbitrary
                 and capricious.

(d)   Review of new  sources

     (1)   The provisions  of  this  paragraph have been incorporated  by refer-
          ence into the applicable  implementation  plans  for  various States,
          as provided in  Subparts  B through ODD of this  part.  Where this
          paragraph is so incorporated, the requirements  of  this  paragraph
          apply to  any new or modified  stationary  source  of  the type iden-
          tified below which  has  not  commenced construction  or modification
          prior to  June  1,  1975  except  as  specifically  provided below.  A

    source which is modified, but does not increase the amount of
    sulfur oxides or participate matter emitted, or is modified to
    utilize an alternative fuel, or higher sulfur content fuel, shall
    not be subject to this paragraph.
    (i)     Fossil-Fuel Steam Electric Plants of more than 1000 mil-
            lion B.T.U. per hour heat input.
    (ii)    Coal Cleaning Plants.
    (111)   Kraft Pulp Mills.
    (iv)    Portland Cement Plants.
    (v)     Primary Zinc Smelters.
    (vi)    Iron and Steel Mills.
    (vii)   Primary Aluminum Ore Reduction Plants.
    (viii)  Primary Copper Smelters.
    (ix)    Municipal Incinerators capable of charging more than 250
            tons of refuse per 24 hour day.
    (x)     Sulfuric Acid Plants.
    (xi)    Petroleum Refineries.
    (xii)   Lime Plants.
    (xiii)  Phosphate Rock Processing Plants.
    (xiv)   By-Product Coke Oven Batteries.
    (xv)    Sulfur Recovery Plants.
    (xvi)   Carbon Black Plants  (furnace  process).
    (xvii)  Primary Lead Smelters.
    (xviii) Fuel Conversion Plants.
    (xix)   Ferroalloy production  facilities commencing construction
            after October 5,  1975.
(2)  No owner  or operator shall commence-construction  or modification
    of a  source subject to this  paragraph unless  the  Administrator de-
    termines  that, on the basis  of information  submitted  pursuant  to
    subparagraph  (3) of this  paragraph:
                              -44-

-------
    (i)     The effect on air quality concentration of the source or
            modified source, in conjunction with the effects of growth
            and reduction in emissions after January 1, 1975, of other
            sources in the area affected by the proposed source, will
            not violate the air quality increments applicable in the
            area where the source will be located nor the air quality
            increments applicable in any other areas.  The analysis of
            emissions growth and reduction after January 1, 1975, of
            other sources in the areas affected by the proposed source
            shall include all new and modified sources granted approv-
            al to construct pursuant to this paragraph;  reduction in
            emissions from existing sources which contributed to air
            quality during all or part of 1974;  and general commer-
            cial, residential, industrial, and other sources of emis-
            sions growth not exempted by paragraph (c) (2) (111) of
            this section which has occurred since January 1, 1975.

    (ii)    The new or modified source will meet an emission limit,
            to be specified by the Administrator as a condition to
            approval, which represents that level of emission reduc-
            tion which would be achieved by the application of best
            available control technology, as defined in 52.01 (f),
            for particulate matter and sulfur dioxide.  If the Admin-
            istrator determines that technological or economic limi-
            tations on the application of measurement methodology to
            a particular class of sources would make the imposition
            of an emission standard infeasible, he may instead pre-
            scribe a design or equipment standard requiring the appli-
            cation of best available control technology.  Such standard
            shall to the degree possible set forth the emission re-
            ductions achievable by implementation of such design or
            equipment, and shall provide for compliance by means which
            achieve equivalent results.

     (iii)   With  respect to modified sources, the requirements of sub-
            paragraph  (2)  (ii) of this paragraph shall be applicable
            only  to the facility or facilities from which emissions
            are  increased.

(3)  In making the determinations required by paragraph  (d)  (2) of this
    section, the  Administrator shall, as a minimum,  require  the owner
    or operator  of the source subject to this paragraph to  submit:
    site information,  plans, description, specifications, and drawings
    showing the  design of  the source;  information necessary to de-
    termine the  impact that the construction or modification will have
    on sulfur dioxide  and  particulate matter air quality  levels;  and
     any other  information  necessary to determine that  best  available
    control technology will be applied.  Upon request  of  the Adminis-
     trator, the  owner  or operator of  the source shall  provide informa-
     tion on the  nature and extent of  general commercial,  residential,
     industrial,  and other  growth which has occurred  in  the  area af-
     fected by  the source's emissions  (such area to be  specified by  the
                              -45-

         Administrator)  since January  1,  1975.

     (4)  (i)     Where a new or modified  source  is located on  Federal
                 Lands,  such source shall be subject to the procedures
                 set  forth  in paragraphs  (d) and  (e) of this section.
                 Such procedures shall be in addition to applicable pro-
                 cedures conducted by  the Federal Land Manager for admin-
                 istration  and protection of the  affected Federal Lands.
                 Where feasible, the Administrator will coordinate his
                 review  and hearings with the Federal Land Manager to
                 avoid duplicate administrative  procedures.

         (ii)    New  or  modified sources  which are located on  Indian
                 Reservations shall be subject to procedures set  forth  in
                 paragraphs (d) and (e) of this  section.  Such procedures
                 shall be administered by the Administrator in cooperation
                 with the Secretary of the Interior with respect  to lands
                 over which the State  has not assumed jurisdiction under
                 other laws.

         (iii)   Whenever any new or modified source is subject to action
                 by a Federal Agency which might necessitate preparation
                 of an environmental impact statement pursuant to the
                 National Environmental Policy Act (42 U.S.C.  4321), re-
                 view by the Administrator conducted pursuant  to  this
                 paragraph  shall be coordinated  with the broad environmen-
                 tal  reviews under that Act, to  the maximum extent feas-
                 ible and reasonable.

     (5)  Where  an  owner  or  operator has applied  for permission to con-
         struct or modify pursuant to  this paragraph and the proposed
         source would be located in an area which has been proposed for
         redesignation to a more stringent class (or the State, Indian
         Governing Body, or Federal Land  Manager has announced such con-
         sideration), approval shall not  be granted until the  Administra-
         tor has acted on the proposed redesignation.

(e)   Procedures  for public participation

     (1)   (i)    Within  20  days after  receipt of an application to con-
                 struct, or any addition  to such application,  the Admin-
                 istrator shall advise the owner or operator of any de-
                 ficiency in the  information submitted  in support of the
                 application.   In the  event of  such a deficiency, the  date
                 of  receipt of the application  for the  purpose of para-
                 graph  (e)  (1)  (11) of this section shall be the  date  on
                 which  all  required  information  is received by the Admin-
                  istrator.

          (ii)   Within  30  days after  receipt of a complete application,
                  the  Administrator shall:
                                  -46-

          (vi)     The  Administrator may  extend  each  of the  time  periods
                  specified  in  paragraph (e)  (1)  (ii),  (iv),  or  (v)  of-this
                  section  by no more than 30  days  or such other  period as
                  agreed to  by  the applicant  and  the Administrator.

     (2)   Any owner or operator who constructs, modifies, or  operates  a
          stationary source  not in accordance with the application,  as ap-
          proved and conditioned by the  Administrator,  or any owner  or op-
          erator of a  stationary source  subject to this paragraph  who  com-
          mences construction or modification after  June 1, 1975,  without
          applying for and receiving approval hereunder, shall be  subject
          to enforcement action under section 113 of the Act.

     (3)   Approval to  construct or modify shall become invalid if  construc-
          tion or expansion  is  not commenced  within  18 months after  receipt
          of such approval or if construction is  discontinued for  a  period
          of 18 months or  more.  The Administrator may extend such time  pe-
          riod upon a  satisfactory showing that an extension is  justified.

          operator of  the  responsibility to comply with the control  strat-
          egy and all  local, State, and  Federal regulations which  are  part
          of the applicable  State Implementation  Plan.

                  does not have continuing responsibilities for  managing
                  land use,  such agency shall consult with  the appropriate
                  State and  local agency which  is primarily responsible  for
                  managing land use prior to  making  any determination  re-
                  quired by  paragraph (d) of  this section.
