                             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 bean 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 reyision
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.

                                  FOR AIR  POLLUTION CONTROL
                                  AS AMENDED JUNE  27,  1975
                                         (420.11-2)
(2.0)    SECTION 1.   TITLE
            The following rules and regulations of the Department  of Pollution  Control
            and Ecology of the State of Arkansas,  adopted  in  accordance  with  the
            provisions of Part II  of the Arkansas  Water and Air  Pollution  Control
            Act, hereinafter referred to as the "Act"  (Ark. Stats.  Ann.  §  82-1901,
            et seq.),  shall  be known as the Regulations of the Arkansas  Plan  of
            Implementation for Air Pollution Control,  hereinafter  referred to
            respectively as  the "Regulations of the Plan"  and "the Plan".

(2.0)    SECTION 2.   PURPOSE

            Promulgation and enforcement of these  Regulations of the Plan  is  intended
            to meet the requirements of the Clean  Air  Act  (42 USCA § 1857, et seq.),
            as interpreted by the  United States Environmental Protection Agency,
            including  but not limited to attainment and maintenance of the National
            Ambient Air Quality Standards.

(1.0)    SECTION 3.   DEFINITIONS

            When used  in these Regulations  of the  Plan:

            (a)  "Arkansas Air Pollution Control Code" means  rules and regulations
                 adopted by  the Department  of Pollution Control  and Ecology of  the
                 State of Arkansas, as amended from time to time,  pursuant to and
                 in furtherance of the Act.  Provisions of the Arkansas  Air Pollu-
                 tion  Control Code shall not be considered a  part  of the Plan except
                 for those provisions specifically described  in  the Plan.

            (b)  "Commission" means the Commission of  Pollution  Control  and Ecology
                 of the State of Arkansas.

            (c)  "Department" means the Department of  Pollution  Control  and Ecology
                 of the State of Arkansas.   When reference is made in these Regula-
                 tions to actions  taken by  or with reference  to  the Department, the
                 reference is to the staff  of the  Department  acting at the direction
                 of the Commission.

            (d)  "Director"  means  the director of  the  Department of Pollution Control
                 and Ecology, acting directly or through the  staff of the  Department.

            (e)  "Equipment" means any device, except  equipment  used for any  mode
                 of transportation, capable of causing the emission of an  air con-
                 taminant into the open air, and any stack, conduit, flue, duct,
                 vent  or similar device connected  or attached to,  or serving  the
                 equipment.
                                               -1-

-------
(f)   "Equipment used in a manufacturing process"  means  equipment,  the
     primary object of which is  the treatment and/or conversion  of
     input materials to produce  a salable or usable  end product.

(g)   "Flue" or "stack" means any conduit or duct  arranged  to  conduct
     an effluent to the open air.

(h)   "Incinerator"  mean-s all devices by which garbage,  refuse, or  other
     combustible material is reduced in volume by a  combustion process
     in which the fuel/air ratio is or can be controlled so that the
     remaining solid residues contain little or no combustible material.

(i)   "Opacity" means the state of a substance which  renders it partially
     or wholly impervious to rays of light so that the  substance par-
     tially or wholly obscures an observer's view.

(j)   "Potential Emission Rate" means the total weight rate at which par-
     ticulate matter is, or in the absence of an  air cleaning device,
     would be, emitted from an air contamination  source when  such  source
     is operated at its maximum  rated capacity.  The potential emission
     rate may be determined by sampling in a flue, prior to the  inlet of
     the air cleaning device, or by estimating the weight  rate of
     emissions by performing a "material balance" (difference between
     process input weight and output weight) for  the process  or  operation,
     or by estimating the weight rate of emissions using estimating
     techniques approved by the  Commission.  When a  number of air  con-
     tamination sources (each of which is capable of being operated
     individually)  are manifolded together so that their emissions are
     discharged to a single flue, the potential emission rate and  allow-
     able emission rate for each source shall be  determined individually.

(k)   "Smoke" means finely divided particulate matter resulting from
     incomplete combustion, consisting primarily  of  carbon and other
     combustible material.

(1)   "Standard Smoke Chart" means the Ringelmann  Chart, as published  by
     the U. S. Bureau of Mines in Information Circular 8333,  dated May,
     1967, photographically reduced to 1/18th in  size for  use in the
     field, or any other method  or device for grading smoke judged by

              ment determines that:

              (A)  The  emissions from  the equipment proposed within the
                  application in  conjunction with the emissions from
                  existing  equipment, if any,  on  the site on which the
                  proposed  new or modified equipment is to be located
                  do not exceed 100 tons/year  potential emissions of
                  particulate matter; and

              (B)  The  location and configuration  of  the proposed equip-
                  ment is such that the emissions as proposed do not
                  prevent the attainment or maintenance of the secondary
                  standard  for particulate matter or the air quality
                  increments provided by the Regulations for the Pre-
                  vention of Significant Deterioration as promulgated
                  by the United States  Environmental Protection Agency.

     The applicant shall  submit such information as the Department may
     reasonably require to make the determinations described in Subsec-
     tions  (A) and  (B)  hereof. Copies of the application, supplemental
     Information  and the  Commission's  determination shall be made a part
     of the permanent record of the applicant and  shall be available for
     public inspection  at the Department's  central office.  The exemption
     from the requirement of a permit  granted by this subsection  (ix)  is
     wholly conditioned on continuing  compliance with the terms of the
     exemption, as granted,  and as set forth  in paragraphs  (A) and  (B)
     hereof.   The Director may cancel  an exemption granted hereunder
     for failure  to  comply with the terms thereof.  Operation of a source
     subject to Section 4 hereof without an exemption having been granted,
     even within  the limits  imposed by (A)  and  (B), and violation of the
     limits set forth  in  (A) and  (B),  even  by a source which has  been
     granted an exemption, shall constitute violations of these regula-
     tions.  Any  person granted an exemption  hereunder shall, nonetheless,
     be subject to the  requirements of Section  7 hereof.

-------
            (h)   Issuance of a permit by this Department does not relieve the
                 applicant of any responsibility to meet all  other requirements
                 of these regulations.

            (i)   Upon completion of the installation,  alteration, or replacement
                 of equipment for which a permit is required, and within 30 days
                 after the equipment has been placed in operation, the Director
                 shall be notified in writing.   The Director  may require the per-
                 mittee to conduct such tests as are necessary to determine whether
                 the equipment complies with the provisions of the permit, or the
                 Director may cause such tests to be made by  agents of the Department.
                 Noncomplying equipment shall be promptly corrected by the permittee.

            (j)   The Director may cancel a permit if the installation or alteration
                 is not begun within 18 months from the date  of the permit or if the
                 work involved in the installation or alteration is suspended for
                 18 months or more from the date of issuance  of the permit.

(10.0)   SECTION  5.   EMISSION LIMITATIONS APPLICABLE TO NEW OR MODIFIED EQUIPMENT

            (a)   No person shall cause or permit the construction or modification  of
                 equipment which would cause or allow applicable emission limitations
                 promulgated by the United States Environmental  Protection Agency  to
                 be exceeded.

            (b)   No person shall cause or permit the construction or modification  of
                 equipment which would cause or allow emissions to exceed the allow-
                 able emission rate as shown on Figure 5(b) of this section.  For
                 purposes of this subsection, process weight  rate means the total
                 weight of all materials introduced over one  hour into any specific
                 piece of equipment directly served by one or more flues or stacks
                 and where the concentration of emissions from such flues or stacks
                 are directly related to the materials introduced to the equipment.
                 It is intended that the above described emission limitations would
                 be applicable to any individual piece of equipment, whether in
                 series or parallel to other pieces of equipment used in the manu-
                 facturing process.  Solid fuels charged are  considered as part of
                 the process weight but liquid and gaseous fuels and combustion air
                 are not.  For a cyclical or batch operation, the process weight
                 rate per hour is derived by dividing the total  process weight by
                 the number of hours in one complete operation from the beginning
                 of any given process to the completion thereof, excluding any time
                 during which the equipment is idle.

            (c)  No person shall  cause or permit the visible emissions from
                 equipment affected by this section to exceed the visible emission
                 limitations as provided in Subsection 8(e)  of these Regulations.

            (d)  Equipment affected by emission regulations  promulgated by the
                 United States Environmental  Protection Agency shall not be affected
                 by the emission  regulations  of Subsection (b) of Section 5, but
                 shall, instead,  be governed  by said regulations of the United States
                 Environmental Protection Agency.

            (e)  The emission limitations of this section may be made more restrictive
                 as such limitations apply to individual pieces of equipment or to
                 areas of the state where the Department finds such more restrictive
                 limitations necessary to prevent the National Ambient Air Quality
                 Standards or air quality increments, as defined by the United States
                 Environmental Protection Agency's Regulations for the Prevention  of
                 Significant Air  Quality Deterioration, from being exceeded.

(7.0)    SECTION 6.   UPSET CONDITIONS, REVISED EMISSION LIMITATIONS

            (a)  Emissions exceeding any of the limits established by the Regulations
                 of the Plan as a direct result of unavoidable upset conditions in the
                 nature of the process, or unavoidable and unforeseeable breakdown
                 of any air pollution control equipment or related operating equip-
                 ment or as a direct result of shutdown or startup of such equipment
                 for necessary scheduled maintenance, shall  not be deemed in violation
                 of these Regulations of the  Plan, provided  the following require-
                 ments are met:

                     (i)  Such occurrence, in the case of unavoidable upset in or
                          breakdown of equipment, shall have been reported to the
                          Director within 24  hours after the occurrence.

                    (ii)  The person responsible for such emission shall submit to
                          the Director, at his request, a full report of such occur-
                          rence,  including a  statement of all known causes and of
                          the scheduling and  nature of the actions to be taken to
                          minimize or eliminate future occurrences, including but
                          not being limited to action to reduce the frequency of
                          occurrence of such  conditions, to  minimize the amount by
                          which said limits are exceeded and to reduce the length  of
                          time for which said limits are exceeded.

                   (iii)  In the  case of shutdown for necessary scheduled mainten-
                          ance, the intent to shutdown shall be reported to the
                          Director at least 24 hours prior to the shutdown; provided,
                          however, that the exception provided by this subsection
                          shall only apply in those cases where maximum reasonable
                          effort  has been made to accomplish such maintenance during
                          periods of non-operation of any related source operation
                          or where it would be unreasonable  or impossible to shut
                          down the source operation during the maintenance period.
                                               -11-

-------
(b)   The emission limitations contained within the Regulations  of the
     Plan are for the purpose of assuring the attainment  and  mainten-
     ance of the National  Ambient Air Quality Standards and have  been
     established within the framework of information  presently  avail-
     able to the Department.   As additional  and more  precise  information
     becomes available, the emission limitations and  reporting  procedures
     of this section may be amended as described below:

         (i)  In accordance with the provisions of the Clean  Air  Act,  as
              amended, and the federal regulations promulgated  pursuant
              to the Clean Air Act, the emission limitations  and  reporting
              procedures of this section may be further amended and made
              more restrictive where the Commission finds more  restrictive
              measures necessary to assure the attainment and maintenance
              of the National Ambient Air Quality Standards.  Depending
              upon the nature of the Commission's finding, the  Commission
              may recommend to the administrator of the Environmental
              Protection Agency that more restrictive emission  limita-
              tions be placed on those sources described  in Sections 5
              and 8 hereof or that additional sources be  placed under
              the requirements of this Plan by including  such additional
              sources and the associated emission limitations within
              Section 8 hereof.

        (ii)  In accordance with the provisions cited in  Subsection (i)
              of this Subsection 6(b), the Commission may recommend to
              the Administrator of the Environmental  Protection Agency,
              on a case by case basis, less restrictive requirements than
              those provided in the Regulations of the Plan upon  its
              findings that the emission limitations  as set forth are
              physically, economically or technologically unattainable
              and that full compliance with the aforecited limitations
              is not necessary to assure attainment or maintenance of
              the National Ambient Air Quality Standards.  Such findings
              shall be made upon the basis of information generally avail-
              able to the Commission and the information  contained within
              the petition for less stringent limitations, which  petition
              may be filed with the Commission by the owner or  operator
              of a source affected by Sections 5 and 8 and which  petition
              shall contain such information and which petition shall be
              filed as soon as the owner or operator of the source deter-
              mines that full compliance cannot be achieved or  that full
              compliance is unnecessary for purposes of attainment of the
              National Ambient Air Quality Standards.

       (iii)  In making determinations with respect to the provisions of
              Subsection (b) hereof, the Commission shall take  into con-
              sideration the following factors:

              (A)  The process, fuels, and raw material available and to
                   be employed in the facility involved.
                                   -12-

-------
                          (B)  The engineering aspects of the application of various
                               types of control  techniques which have been adequately
                               demonstrated.

                          (C)  Process and fuel  changes.

                          (D)  The respective costs of the application of all  such
                               control techniques, process changes, alternative
                               fuels, etc.

                          (E)  Locational  and siting considerations.

                    (iv)  In no case shall the Commission recommend,  approve or con-
                          done less stringent emission limitations than those set
                          forth in these Regulations where less stringent limitations
                          would prevent the attainment of the National Ambient Air
                          Quality Standards or would cause applicable air quality
                          increments, as provided in Subpart A, Part 52, Chapter I,
                          Title 40, Code of Federal Regulations, to be exceeded.
(9.0)    SECTION 7.   SAMPLING AND MONITORING REQUIREMENTS

            (a)  Sampling
                     (i)  Any person owning or operating equipment shall, upon re-
                          quest, by the Director, conduct sampling to determine the
                          opacity, rate, composition, and/or concentration of such
                          emissions.  Sampling shall  be conducted at a frequency
                          and within a period of time as specified by the Director.
                          The sampling method shall  be specified by the Director and,
                          further, the sampling shall be conducted so as to reflect
                          with reasonable accuracy characteristics of such emissions.
                          Any person affected by this regulation may request the
                          Director to approve alternate sampling techniques or other
                          means to determine the opacity, rate, composition, and/or
                          concentration of emissions.  The Director may approve such
                          alternate methods or means  if it can be demonstrated that
                          such alternatives will be substantially equivalent to the
                          sampling methods specified  by the Director or the Commission.

                    (ii)  Copies of all data, computations and results obtained under
                          this regulation shall be retained by the owner or operator
                          of a source for at least five (5) years and shall be made
                          available to the Commission or any members, employees or
                          agents thereof, during regular business hours.
            (b)  Sampling Ports
                     (i)  Any person owning or operating equipment shall, upon request
                          of the Director, provide, in connection with each flue, a
                          power source near the point of testing in addition to such
                          sampling and testing facilities and sampling ports, includ-
                          ing safe and easy access thereto, exclusive of instruments
                                               -13-

-------
              and sensing devices, as may be necessary for the Deparc-
              ment to determine the nature and quality of emissions
              which are or may be discharged as a result of operations
              of the equipment served by the flue.

              Evidence and data based on these samples and calculations
              may be used to substantiate violations of the Act or the
              Regulations of the Plan.  Agents of the Department shall
              be permitted to sample the stacks during operating hours.

(c)   Filing of Emissions Data

         (i)  Upon request by the Director, any person affected by any
              Regulation of the Plan or by the Arkansas Air Pollution
              Control Code shall file emissions data with the Department
              on forms supplied by the Department.

(d)   Sampling Procedures and Terminology

         (i)  Where not otherwise specified in Regulations of the Plan,
              and orders of the Commission, the procedures used for
              sampling air and measuring air contaminants, and the
              methods of expressing the findings shall be those commonly
              accepted and used in the field of air pollution control.

(e)   Continuous Monitoring

         (i)  The Director may require the owner or operator of any air
              contaminant source to install, use, and maintain such
              monitoring equipment; sample such emissions in accordance
              with methods as the Director shall prescribe; establish
              and maintain such records; and make such periodic emission
              reports as required below.

(f)   Reporting General Process Information

         (i)  The owner or operator of any equipment shall, upon request
              of the Director, supply such information, as the Director
              may reasonably require and as may be necessary, to deter-
              mine the impact that the operation of such equipment has,
              or will have, on air quality levels.   Such information shall
              be made on forms made available by the Department or in a
              format prescribed by the Director.

(g)   Reporting Emission Data

         (i)  The owner or operator of any equipment shall, upon notifi-
              cation by the Director, maintain records of the nature and
              amount of emissions, to which an air quality control emission
              regulation applies, from the source and any other information
              (in addition to that data required above) as may be deemed
              necessary by the Director to determine whether the source
              is in compliance with applicable regulations.
                                   -14-

-------
                    (ii)  The information recorded shall  be summarized and reported
                          to the Director, on forms furnished by the Director, and
                          shall  be submitted within 45 days after the end of the
                          reporting period.  Reporting periods are June 1 through
                          November 30 and December 1  through May 31  or such other
                          periods as the Director may specify.  Information reported
                          to the Director shall  be signed by the person responsible
                          for its accuracy.

                   (iii)  Emission data obtained by the Director shall be correlated
                          with applicable emission limitations and other control
                          measures and be made available to the public during normal-
                          business hours.

(6.0)   SECTION 8.   COMPLIANCE SCHEDULES AND EMISSION LIMITATIONS APPLICABLE TO

         ment of Pollution Control and
         Ecology;

     (2) Date by which contracts for emis-
         sion control systems or process
         modifications will be awarded;
         or date by which orders will be
         issued for the purchase of compo-
         nent parts to accomplish emission
         control or process modification;

     (3) Date of initiation of on-site
         construction or installation of
         emission control equipment or
         process change;

     (4) Date by which on-site construc-
         tion or installation of emission
         control equipment or process modi-
         fication is to be completed;

     (5) Commencement date or operation of
         with emission control system in
         place and functioning; and

 (B)  The equipment utilization, on annual average, does
     not exceed the percent utilization given for each
     piece of equipment as described above under CSN 630010.
     For purposes of this regulation, annual equipment
                      -24-

-------
     utilization for similar pieces  of equipment serving
     parallel  processes located in the same building and
     having identical  allowable emission rates,  may be
     determined by computing an equivalent annual  average.
     An equivalent annual  average is computed by summing
     the number of hours which each  of (N) similar pieces
     of equipment is operated during a year and  dividing
     that sum by the product of (N)  and 8,760 hours.  The
     owner or operator of the equipment affected by this
     requirement shall maintain such records as  may be
     necessary to assure the Director that the equipment
     utilization rates as provided above are not exceeded.

(C)   The requirements  of Subsection  (B) above shall be
     rescinded upon full attainment  of the emission limi-
     tations provided above for the  equipment in Buildings
     425 and 426.

 (ii)   Stone  Quarrying  and  Crushing  Operations

       (A)  The  requirements  of  this subsection shall apply to
           limestone and crushing operations having a primary
           crushing capacity of 300 tons per hour and to all
           other  stone quarrying and crushing operations having
           a primary crushing capacity  of  500 tons per hour.

       (B)  Prior  to September 1, 1975,  owners and operators of
           quarrying and crushing operations affected by the
           provisions  of this subsection shall notify the Depart-
           ment in writing as to the location of said quarrying
           and  crushing operations  and  shall describe the nature
           of the operation, the capacity  of the equipment used
           at said location, and the nature and estimated effi-
           ciency of air pollution  control techniques employed
           at said location.

       (C)  No person shall cause or permit the operation of a
           quarrying and crushing operation affected by the pro-
           visions of  this subsection in a manner which would
           allow  excessive and  unnecessary amounts of particu-
           late matter to  become airborne.  For purposes of this
           requirement, wet  sprays  on the  inlets and outlets of
           crushers, or equivalent  controls, shall be considered
           minimal controls  necessary to prevent unnecessary
           amounts of  particulate matter from becoming airborne.
           No quarrying or crushing facility shall be permitted
           to operate  in a manner which would cause visible
           emissions to extend  beyond the  property line of the
           affected facility or which would interfere with the
           attainment  and  maintenance of the National Ambient
           Air  Quality Standards.

(iii)   Rice and  Soybean Processing Facilities

       (A)  The  requirements  of  this section shall apply to
           facilities  known  as  rice mills  and soybean processing
           plants.   It is  not intended  that these regulations
           apply  to facilities  designed for the drying and
           storage of  rough  rice or soybeans.

       (B)  No person  shall cause or permit the operation of
           facilities  affected  by the provisions of this sub-
            section  in  a manner  which would allow the emission
           of particulate  matter from said facilities  to exceed
            1.5  pounds  for  each  ton  of rice or soybeans processed.

 (iv)   Asphalt (Mix)  Concrete Plants

       (A)   No person  shall cause or permit the operation of  an
            asphalt  concrete plant,  constructed or modified  after
                            -34-

-------
                               June 11,  1973,  to exceed  the  Standards  of Per-
                               formance  for New Stationary Sources  (40 CFR  60.90)
                               as promulgated  by the United  States  Environmental
                               Protection Agency.

                          (B)   After June 1, 1976,  no person shall  cause or permit
                               the operation of an  asphalt concrete plant,  constructed
                               or modified prior to June 11, 1973,  except as specified
                               herein.   Prior  to commencement of operation  at  any
                               location, the owner  or operator shall  notify the
                               Director  in writing  of the location  of the asphalt
                               concrete  plant, stating the capacity of the  plant,
                               the control equipment to  be used and the expected
                               rate of emissions.   Upon  receipt of  such notification,
                               the Director may authorize the operation as  proposed
                               by said owner or operator or  may require, where the
                               plant is  proposed to be operated in  areas of high
                               population density or areas in which the National
                               Ambient Air Quality  Standards are threatened, more
                               stringent controls than proposed by  said owner  or
                               operator.  In no case, however, shall  the Director
                               approve or authorize the  operation of an asphalt
                               plant from which the emissions exceed 100 Ibs./hr.
                               or 1000 Ibs./day.

                          (C)   Routine maintenance, repair and replacement, relocation
                               of a portable plant, change of aggregate, and transfer
                               of ownerships are not considered modifications  which
                               would require a plant which was constructed  prior to
                               June 11,  1973 to comply with  the provisions  of  sub-
                               section (A) of this  subsection.

                          (D)   Portable  asphalt concrete plants which  relocate after
                               June 30,  1975 shall, upon said relocation, comply
                               fully with the  provisions of  subsection (B)  of  this
                               subsection.

                          (E)   Except as provided by the provision  of subsection  (B)
                               of this subsection,  portable  asphalt concrete plants
                               which were constructed or modified prior to  June 11,
                               1973 shall not  be affected by the visible emission
                               limitations of the Regulations of the Plan.
(2.0)    SECTION 9.   SEVERABILITY
            If any provision of the Regulations of the Plan or the application thereof
            to any person or circumstance is held invalid,  such invalidity shall  not
            affect other provisions or applications of the  Regulations  of the Plan
            which can be given effect without the invalid provision or  application,
            and to this end the provisions of the Regulations of the Plan are declared
            to be severable.

                  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  th« 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

             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
                              -45-

-------
              (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.
                               -46-

-------
(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.

            (b)   Regulation for public availability of eirissior data.

                 (1)  Any person who cannot obtain emission data from the Agency
                     responsible for making emission data available to the public,
                     as specified in the applicable plan, concerning emissions  from
                     any source subject to emission limitations which  are part  of
                     the approved plan may request that the appropriate Regional
                     Administrator obtain and make public such data.  Within 30
                     days after receipt of any such written request, the Regional
                     Administrator shall require the owner or operator of any such
                     source to submit information within 30 days on the nature  and
                     amounts of emissions from such source and any other information
                     as may be deemed necessary by the Regional Administrator to
                     determine whether such source is in compliance with applicable
                     emission limitations or other control measures that are part
                     of the applicable plan.

                 (2)  Commencing after the initial notification by the  Regional
                     Administrator pursuant to paragraph (b)(l) of this section,
                     the owner or operator of the source shall maintain records of
                     the nature and amounts of emissions from such source and any
                     other information as may be deemed necessary by the Regional
                     Administrator to determine whether such source is in compliance
                     with applicable emission limitations or other control measures
                     that are part of the plan.  The information recorded shall be
                     summarized and reported to the Regional Administrator, on forms
                     furnished by the Regional Administrator, and shall be submitted
                     within 45 days after the end of the reporting period.  Reporting
                     periods are January 1-Oune 30 and July 1-December 31.

                 (3)  Information recorded by the owner or operator and copies of this
                     summarizing report submitted to the Regional Administrator shall
                     be retained by the owner or operator for 2 years  after the date
                     on which the pertinent report is submitted.

                 (4)  Emission data obtained from owners or operators of stationary
                     sources will be correlated with applicable emission limitations
                     and other control measures that are part of the applicable plan
                     and will be available at the appropriate regional office and at
                     other locations in the state designated by the Regional Admin-
                     istrator.

             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

        (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  have
        not  assumed such  authority  under other laws  nor is it
        intended to deny  jurisdiction  which States have assumed
                        -51-

-------
        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.
                         -52-

-------
                  (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
                                  -53-

    source which is modified, but does not increase the amount of
    sulfur oxides or particulate 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.
    (iii)   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:
                             -54-

-------
     (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
                             -55-

         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
                 which  all  required  information  is  received  by the  Admin-
                  istrator.

          (ii)    Within  30  days  after receipt of a  complete  application,
                  the  Administrator shall:
                                 -56-

-------
        (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.
                         -57-

-------
          (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
