                             INTRODUCTION
     This document has been produced in compliance with Section 110(h)(l)
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

-------
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 enforceafaility 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.

                               RULES AND  REGULATIONS
                  Consistent with  a  coordinated  state-wide  program  to control present
             and future sources .of emissions  to  the  end  that air  polluting activities
             of every type shall be  regulated in a manner that  reasonably insures the
             continued health,  safety and general welfare of all  the citizens of the
             state;  protects property values  and protects plant and animal life; and
             pursuant to 38 M.R.S.A., Section 585, the Department of Environmental
             Protection adopts  the following  emission standards and regulations
             designed for the achievement and maintenance of ambient air quality
             standards and the  prevention of  air pollution:
(1.0)         10.0 DEFINITIONS
                  Air contaminants include,  but are not limited to,  dust,  fumes,  gas,
             mist, particulate matter,  smoke,  vapor or any  combination  thereof.

                  Air pollution control  apparatus  means and includes any appliance,
             equipment, machinery, installation or structures  which  remove,  control,
             reduce, eliminate, dispose of or  render less noxious  the emission  of air
             contaminants into the ambient air.

                  Ambient air means all  air outside of buildings,  stacks or  exterior
             ducts.

                  Best practical treatment means that method which controls  or  reduces
             emissions of air contaminants to  the lowest possible  level considering:

                  1.  The then existing state  of technology:

                  2.  The effectiveness of available alternatives  for reducing
                      emissions from the source being considered:

                  3.  The economic feasibility for the type of establishment involved.

                  Board means the Board of Environmental Protection.

                  Commissioner means the Commissioner of the Department of Environmental
             Protection.

                  Emission means a release of air contaminants into ambient air.
                  Emission source means any and all sources of emissions of air
             contaminants, whether privately or publicly owned or operated.

                  Fuel-burning equipment means any furnace, boiler, apparatus, stack,
             and all appurtenances thereto, used in the process of burning fuel for
             the primary purpose of producing heat or power by indirect heat transfer.

                  Fugitive dust means solid air-borne particulate matter emitted from
             any source other than a flue or stack.
                                                -1-

-------
     General Process source means any emission source except fuel-
burning equipment, incinerators, mobile sources, open burning sources
and sources of fugitive dust.

     Incinerators means any device, apparatus, equipment or structure
used for destroying, reducing or salvaging by fire any material  or
substance.

CLASSIFICATION OF WASTES

     Type 0—Trash, a mixture of highly combustible waste such as paper,
cardboard cartons, woodboxes and combustible floor sweepings, from
commercial and industrial activities.  The mixtures contain up to 10%  by
weight of plastic bags, coated paper, laminated paper, treated corrugated
cardboard, oily rags and plastic or rubber scraps.  This type of waste
contains about 10% moisture and 5% incombustible solids and has  a heating
value of approximately 8500 B.T.U. per pound as fired.

     Type 1—Rubbish, a mixture of combustible waste such as paper,
cardboard cartons, wood scrap, foliage and combustible floor sweepings,
from domestic, commercial and industrial activities.  The mixture contains
up to 20% by weight of restaurant or cafeteria waste, but contains  little
or no treated papers, plastic or rubber wastes.  This type of waste
contains about 25% moisture and 10% incombustible solids and has a  heating
value of approximately 6500 B.T.U. per pound as fired.

     Type 2—Refuse, consisting of an approximately even mixture of  rubbish
and garbage by weight.  This type of waste is common to apartment and
residential occupancy, consisting of up to 50% moisture, 7% incombustible
solids, and a heating value of approximately 4300 B.T.U. per pound  as  fired.

     Type 3—Garbage, consisting of animal and vegetable wastes  from
restaurants, cafeterias, hotels, hospitals, markets and like installations.
This type of waste contains up to 70% moisture, and up to 5% incombustible
solids and has a heating value of approximately 2500 B.T.U. per pound  as
fired.

     Type 4--Human and animal remains, consisting of carcasses,  organs
and solid organic wastes from hospitals, laboratories, abattoirs, animal
pounds, and similar sources, consisting of up to 85% moisture, 5% incom-
bustible solids and having a heating value of approximately 1000 B.T.U.
per pound as fired.

     Type 5—By-product waste, gaseous, liquid or semi-liquid, such  as
tar, paints, solvents, sludge, fumes, etc., from industrial operations.
B.T.U. values must be determined by the individual materials to be  destroyed.

     Type 6—Solid by-product waste, such as rubber, plastics, wood waste,
etc., from industrial operations.  B.T.U. values must be determined by the
individual materials to be destroyed.

CLASSIFICATION OF INCINERATORS

     Class I—Portable, packaged,  completely  assembled,  direct fed
incinerators 5 to 15 cubic feet primary chamber volume;  or  a  burning
rate of 25 to 100 pounds per hour  of type 1 or type  2 waste;  or a
burning rate of 25 to 75 pounds per hour of type 3 waste.

     Class IA—Portable, packaged  or job assembled,  direct  feed
incinerators with 5 to 14 cubic feet primary  chamber volume;  or a
burning rate ot 25 to 100 pounds per hour of  type 1  or  type 2 waste;
or a burning rate of 25 to 75 pounds per hour of type 3 waste.

     Class II—Flue-fed, single chamber incinerators with more than 2
square feet burning area, for type 2 waste.   This type  of incinerator
is served by one vertical flue functioning both as a shute  for charging
waste and to carry the products of combustion to atmosphere.  This type
of incinerator has been installed  in apartment houses or multiple dwell-
ings.

     Class IIA—Shute-fed multiple chamber incinerators, for  apartment
buildings with more than 2 square  feet burning area, suitable for type
1 or type 2 waste.  (Not recommended for industrial  installation) This
type of incinerator is served by a vertical  shute for charging wastes
from two or more floors above the  incinerator and a  separate  flue for
carrying the products of combustion to the atmosphere.

     Class III—Direct fed incinerators with  a burning  rate of 100
pounds per hour and over, suitable for type  3 waste.

     Class IV—Direct fed incinerators with  a burning rate  of 75 pounds
per hour or over, suitable for type 3 waste.

     Class V—Municipal incinerators suitable for type  0, type 1, type
2 or type 3 wastes, or a combination of all  four wastes, and  are rated
in tons per 24 hours.

     Class VI—Crematory and pathological incinerators, suitable for
type 4 waste.

     Class VII—Incinerators designed for specific  by-product wastes,
type 5 or type 6.

     Modification means any physical change  to or change in the method
of operation of, an affected facility which  increases  the amount of any
air pollutant (to which a standard applied)  emitted  by  such facility
or which results in the emission of any air  pollutant  (to which a  stand-
ard applies) not previously emitted, except  that:

              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.

      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.

                  proposed redesignation are notified at least 30 days
                  prior to the public hearing, and
                              -37-

-------
        (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

             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  have
        not assumed such authority  under other laws nor is  it
        intended to deny jurisdiction  which States have assumed
                        -38-

        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-

            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
        fol1ows:

        (a)  Any redesignation  proposed pursuant to subdivisions
             (ii) and (iii)  of  this subparagraph shall be approv-

             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

             ily and capriciously disregarded relevant consider-
             ations  set forth  in  subparagraph  (3) (ii) (d)  of this
             paragraph.

                  (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.

                      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.

     (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

            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
                             -42-

         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)  (ii) of this section  shall be the date  on

                 the  Administrator shall:
                                 -43-

-------
        (a)   Make a preliminary determination whether the  source
             should be  approved, approved  with  conditions,  or  dis-
             approved.

        (b)   Make available  in  at least  one  location  in  each re-
             gion in which the  proposed  source  would  be  construct-
             ed,  a copy of all  materials submitted  by the  owner or
             operator,  a copy of the  Administrator's  preliminary
             determination and  a copy or summary  of other  materi-
             als, if any, considered  by  the  Administrator  in mak-
             ing  his preliminary determination;  and

        (c)   Notify the public, by prominent advertisement in
             newspaper  of general  circulation in  each region in
             which the  proposed source would be constructed, of
             the  opportunity for written public comment  on  the in-
             formation  submitted by the  owner or  operator  and  the
             Administrator's preliminary determination on  the  ap-
             provability of  the 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  locations where the
        source will be  situated as follows:  State  and local air
        pollution control agencies, the  chief executive  of the
        city and  county, any comprehensive  regional  land  use  plan-
        ning agency; and any State,  Federal Land Manager  or In-
        dian Governing  Body  whose lands  will be significantly  af-
        fected by the source's  emissions.

(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  sub-
        mit  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  source  would be located.

(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  source  would be lo-
        cated.
                         -44-

-------
          (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.

     (4)   Approval to construct or modify  shall not relieve any owner or
          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.

(f)   Delegation of authority

     (1)   The Administrator  shall have the authority to  delegate responsi-
          bility for implementing the procedures  for conducting source  re-
          view  pursuant to paragraphs (d)  and (e), in accordance with sub-
          paragraphs (2),  (3),  and  (4) of this paragraph.

     (2)   Where the  Administrator delegates the responsibility for imple-
          menting the  procedures  for  conducting source review pursuant  to
          this  section  to any Agency, other than  a regional office of the
          Environmental Protection Agency, the following provisions shall
          apply:

          (i)    Where the  agency designated is  not an  air pollution con-
                 trol  agency,  such agency shall  consult with the appropri-
                 ate  State  and local air pollution control agency prior to
                 making any determination required by paragraph  (d) of
                 this  section.  Similarly, where the agency designated
                 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.

          (ii)    A  copy of the notice pursuant  to  paragraph  (e)  (1)  (ii)
                  (c)  of this  section shall be sent  to  the Administrator
                  through  the  appropriate regional office.
                                   -45-

(3)   In accordance with Executive Order 11752,  the Administrator's
     authority for implementing the procedures  for conducting  source
     review pursuant to this section shall  not  be delegated, other  than
     to a regional office of the Environmental  Protection  Agency, for
     new or modified sources which are owned or operated by  the  Federal
     government or for new or modified sources  located  on  Federal lands;
     except that, with respect to the latter category,  where new or
     modified sources are constructed or operated on  Federal lands  pur-
     suant to leasing or other Federal agreements, the  Federal land
     Manager may at his discretion, to the  extent permissible  under ap-
     plicable statutes and regulations, require the lessee or  permittee
     to be subject to a designated State or local  agency's procedures
     developed pursuant to paragraphs (d) and (e)  of  this  section.

(4)   The Administrator's authority for implementing the procedures  for
     conducting source review pursuant to this  section  shall not be re-
     delegated, other than to a regional office of the  Environmental
     Protection Agency, for new or modified sources which  are  located
     on Indian reservations except where the State has  assumed juris-
     diction over such land under other laws, in which  case  the  Admin-
     istrator may delegate his authority to the States  in  accordance
     with subparagraphs (2), (3), and (4) of this paragraph.
