              Enclosed is a copy of -an IE/ample Scope of Work for Contracts
         to Prepare SIP Revisions to/wttVin and Maintain NAAQS".   Comments  received
         from reviewers of ari earlier draft have been incorporated.

              The purpose of this example is to assist the Regional  Offices  in
         providing guidance to States developing Air Quality Maintenance Plans or
         other SIP revisions.

              Parts of the example were developed from portions of completed con-
         tracts provided by Tom Williams, Program Resources Section, Control Pro-
         grams Operations Branch, CPDD.  However, these contracts did not contain
         extensive information on strategies or plan development, and material from
         other sources was therefore used to develop portions of the example con-
         tract dealing with those subjects.  In the case of the section  on
         Preparation of SIP Revisions, the material is basically a summary  of
         the requirements of 40 CFR Part 51 Subpart D regulations.

              We believe that many States which need (contractual) assistance are
         still in the early stages of developing SIP revisions, and the  RO  should
         find this material helpful in assisting those States.  The material may
         also be helpful in preparing (contractual) assistance for upgrading
         emission inventories, providing modeling assistance, etc.,  and  preparing
         SIP revisions, in the future.

              It is anticipated that in many cases States and Regional Offices will
         want to focus on certain aspects of analysis and plan development  at a
         particular time or in a specific contract.  For that purpose, portions of the
         example can be excerpted as needed.

              We would like to thank those who have commented on the previous draft.

                       INSTRUCTIONS FOR USE

                EXAMPLE SCOPE OF WORK FOR CONTRACTS
                     TO PREPARE SIP REVISIONS
I.   PURPOSE OF EXAMPLE
     This example Scope of Work is  intended to show what  tasks  should
be considered in preparing contracts to develop SIP  revisions for
attainment and/or maintenance of the NAAQS where the  provisions  of
40 CFR 51 Subpart D apply.
     As specified in 40 CFR Part 51 regulations, the  State  has
responsibility for developing the SIP revisions for  attainment  and
maintenance of NAAQS (hereafter referred to as "SIP  revisions"), and
in many cases, the State may perform all of the tasks themselves.
However, it is assumed for purposes of this example that  a  contrac-
tor will develop the SIP revisions  for the State under the  direction
of an EPA Project Officer.
     The tasks and procedures described in this example are based
on 40 CFR Part 51 regulations, with emphasis on the provisions  of
Subpart D published Kay 3, 1976 (40 FR 18382).  Some  of the indivi-
dual tasks and procedures are not specifically required by  the
regulations, but are based on recommendations  contained in  the  Air
Quality Maintenance Guidelines or related guidelines.  These tasks
and procedures are included here in order that the contract Project
Officer may consider them in writing a scope of work  to meet spe-
cific needs as well as to complete  the detailed tasks necessary  to
comply with the regulations.

-------
     The extent to which elements of this example  are  used will  depend
on the relative severity of the problems  being confronted  and  the re-
sources which are available.   A metropolitan  area  with complex attain-
ment/maintenance problems will need detailed  analyses  performed  and
comprehensive strategies developed if the air quality  problems are to
be effectively resolved.  Other areas where problems  are  less  corrplex
may not need as much effort spent on analyses or strategies and  the
level of detail will be less.
     The general work areas to be considered  are baseline  data collec-
tion, emission problems, emission allocations, modeling,  analysis of
modeling results, strategy testing and preparation of  the  revisions
themselves.
     References which may be helpful to Project Officers  and contrac-
tors are included in an Appendix.
II.  PROCEDURES
     Once a contract to develop a SIP revision is  awarded, the fol-
lowing general procedures should be used.
A.   Detailed Work Plan
     Before a contractor performs any extensive data  gathering,
compiles emissions and air quality data, performs  any modeling cal-
culations, or undertakes any other major tasks, he should meet with
the Project Officer or his representative, during  the  first week or
two of the contract to outline a detailed work plan.   This work plan
should include a time schedule for completion of major steps;  identity

-------
of persons who will perform the work; hours  to  be  spent  by each; de-
tailed costs, Including labor, travel, printing and  overhead; and a
complete description of the specific methodologies to be used,  in-
cluding a discussion of any necessary computer  work.  After the work
plan is developed, the contractor should meet with the Project  Officer,
State and local  pollution control agencies,  describe the plan,  and
solicit comments and suggestions on  the applicability of the plan for
meeting the specific needs of the area.   Comments  should be incorpora-
ted into the plan, and additional elements of the  plan should be
developed to resolve any remaining problems.  Once the work plan is
approved by the Project Officer, the contractor should be required to
follow it completely and no changes  should be allowed without the
written approval of the Project Officer.  If any changes  are necessary,
the contractor should describe the details in writing together with
the amount of additional work required.
B.   Development of SIP Revisions
     The contractor should be required to perform  all work on the SIP
revisions in accordance with applicable 40 CFR  Part  51 regulations,
including Subpart D published May 3, 1976 (40 FR 18382),  and applicable
Guidelines for Air Quality Maintenance Planning and  Analysis.   The
Project Officer should specify which of the  guidelines are applicable.
In order to ensure that the SIP revisions will  be  effectively imple-
mented and enforced, it is important that the contractor, under the
direction of the Project Officer, consult and coordinate  with State

-------
and local  agencies and other agencies  identified  under Section 51.58
of the 40  CFR Part 51  regulations,  during the entire development of
the revisions.
     The contractor should also  maintain contact with the Project
Officer during the entire  period of the contract,  and meet with him
as necessary.  Any difficulties  that may affect completion of the
project tasks on  schedule  should be indicated to the Project Officer
as soon as they become evident.
C.   Model i ng Requi rements
     Recommended simulation models  are given 1n Volume 12 of the Main-
tenance Guidelines.  The models  actually used will depend upon the re-
sources, and technical expertise,  as well as the  detail  and accuracy
of emissions, meteorological  and air quality data  which  are available.
Before preparing a scope of work for a specific contract involving
modeling,  the Project Officer should check with the Source Receptor
Analysis Branch, Monitoring and  Data Analysis Division of OAQPS for
the latest guidance on recommended  models.
     Whenever possible, the Project Officer should specify in the
scope of work the number of strategies which are  to be tested, as well
as the number of air quality projections required, in order that the
number of modeling runs can be determined.
     A minimum of 3 modeling runs will be required for air quality
analysis per 40 CFR 51.51, plus  a  run  for each strategy  to be tested
for the last year in which the plan is to be effective,  and any other
Intermediate year which may be specified per 40 CFR 51.53.

-------
D.   Review of Past Studies
     The Project Officer should provide copies  of any pertinent  past
studies conducted in the area, as well  as  copies  of all  available
emissions and air quality data from NEDS and SAROAD.   The  contractor
should thoroughly review these studies  and data for use  in the con-
tract.
E-   Definition of the Area
     In order for a SIP revision to be  realistic  and effective,  the
area to which it applies should be specifically defined.   Although
168 areas have been designated as Air Quality Maintenance  Areas  (as
described in Volume 14 of the Guidelines), a State may develop an
attainment/maintenance plan for any other  area  which  is  found to
need one, in accordance with the provisions of  Section 51.12.  How-
ever, in each case the jurisdictional boundaries  of the  area should
be clearly identified, in order that the correct  emissions data  will
be used as input to the models, and effective strategies can be
developed.  Where important sources and/or receptors  are outside of
the study area, provision should be made to explicitly consider  them
in the study area analysis.
F.   Level of Detail
     Updating of the emissions inventory,  projecting  emissions,  and
allocating emissions can be performed using Level  or  Order 1, 2, or
3 procedures as described 1n Volumes 7  or  13.   It  is  assumed for
the purpose of this example that the most  detailed and accurate  level
(or order) 3 procedures are used.   However, the Project  Officer  may
specify levels (orders) 1 or 2 in accordance with  the requirements of
the models to be used, and the resources available.
                                5

-------
G.   Modular Sections
     This example Scope of Work is written  in sections,  and  the  Project
Officer may select only those sections  or portions  of sections which
apply to his needs.  Some tasks, such as  updating the emission inven-
tory, may have already been completed,  in which  case, the  Project
Officer will want to use only the applicable  sections.   Other tasks
may not be required if the Project Officer  considers  them  to be  un-
necessary to a particular project or if resources do  not permit  them.
H.   Alternative Procedures
     The Project Officer may wish to add  tasks not  included  in this
example or substitute other tasks.  As  provided  for in 40  CFR 51.63,
a State may request the approval of the Regional Administrator to
use alternative procedures for conducting certain portions of the
analysis and development of proposals for SIP revisions.   For any such
tasks, the Project Officer should specify in  the scope of  work exactly
what requirements must be met and what  problems  are to be  addressed
by the contractor.
I.   Forthcoming Techniques
     A feasibility study has been started (as of August  1, 1976) by
Argonne National Laboratory for the development  of  a  Computerized
Emissions Projection and Allocation System  (CEPA).  The  existing sys-
tems being evaluated are:
     1.  Manual System, using Volumes 7 and 13 of the Guidelines Series,
     2.  Automated System using entirely  new  software based  on Volumes
         7 and 13 of the Guidelines Series.

-------
      3.  Automated System incorporating all or some of the following,
         in whole or in part:
         a.  Computer-Assisted Area Source Emission Gridding Proce-
             dure (CAASE)
         b.  Regional Emission Projecting System (REPS)
         c.  Air Quality for Urban and Industrial  Planning (AQUIP).
     The feasibility study is due to be completed by April 1977.   If
EPA decides to develop CEPA based upon the feasibility study results,
the model will be ready about December 1977.   In that case, this  ex-
ample scope of work will be modified to include the CEPA material.
J.   Distribution of Report
     When the contractor has completed the report, he will submit an
appropriate number of copies to the Project Officer.   The contractor
will also submit detailed data and calculations used in analysis  and
development of the SIP revisions.  The Project Officer should then
send copies of the report, and the detailed data and calculations to
the appropriate State and local agencies  responsible for submitting
the SIP revisions to EPA.   These agencies  can  retain the data and
calculations and modify the contractor's  report as they desire for
submittal to EPA.

                       EXAMPLE SCOPE OF WORK
  I.  INTRODUCTION
     The scope of work shall identify the area for which the SIP
revisions will be developed.  Important sources outside the area shall
also be included in the analysis.  All  work shall  be performed in
accordance with the 40 CFR Part 51 regulations  concerning require-
ments for preparation, adoption, and submittal of  implementation plans
and the Guidelines for Air Quality Maintenance Planning and Analysis
as appropriate.  In case of a conflict  between the Guidelines  and the
regulations, the regulations shall govern.   The Project Officer will
specify those guidelines or parts thereof which are applicable.   Vari-
ance from the methods and procedures specified shall  be made only with
his concurrence.  If any tasks are affected by changes  in the  Guide-
lines or regulations, the contractor shall  negotiate  any additional
costs with the Contracts Office.
II.  WORK PLAN
     Prior to starting work on the SIP  revision, the  contractor shall
meet with the Project Officer, and all  State and local  agencies  spe-
cified by the Project Officer, and prepare  a detailed work plan.   The
work plan shall describe the major tasks to be performed, a time
schedule for completion of each task, cost  breakdown  by tasks, and
a complete description of the specific  methodologies  to be used, in-
cluding any computer work.  The contractor  shall present this  work plan
to the Project Officer and the agencies specified  by  him.   Any changes

-------
suggested by them and considered necessary  by the  Project  Officer,
shall be incorporated by the contractor insofar as  allowed by the gen-
eral scope of work.   Any additional  costs shall  be  handled through the
Contracts Office.  Once the work plan  is approved  by the Project Officer,
no deviation from the plan will  be permitted  without written approval
of the Project Officer.
III. BASELINE DATA
A.   Emission Inventory
     1.   For the pollutants specified  by the  Project Officer, the con-
tractor shall update (or develop) an inventory of  annual emissions for
point, area, and line sources using the National Emission  Report (NER)
                              P
format, (Table 7.1 in Volume 7 ) and using  the updating procedures des-
cribed in Volume 7.   Level 3 procedures described  in Volume 7,  (the most
detailed and accurate) shall be  used unless otherwise  specified by the
Project Officer.  The contractor shall submit summaries of baseline emis-
sions in accordance  with 40 CFR  51.51.
     2.   For those pollutants being studied the point  source inventory
shall include any facility which has the potential  to  emit 100  tons or
more per year of any pollutant.   The contractor shall  obtain  (or develop)
the information needed to model  these  point sources such as stack height,
diameter, temperature, and velocity of stack  gases, etc.
     3.   Potential emissions shall be  defined as being the emissions
that would occur if any existing control equipment were removed or
deactivated.  (Potential emissions are calculated  by  dividing the exis-
ting annual emissions estimate by the  factor  one minus the efficiency
of the control device, if any).

-------
     4.  For interstate areas, unless  alternative  procedures  are approved
by the Administrator under § 51.63, the same  regional  emission  inventory
shall be used as the basis for analysis in the  constituent  states  as
specified in 40 CFR 51.48.
     5.  All emissions data collected  and updated  under  this  contract
that have not been previously sent to  EPA shall  be submitted  in machine
readable format to the EPA Regional Office Aeros contact.   This data
shall also be made available to the State if  the Project Officer deter-
mines that it is needed to update their files.
     6.  Coding and keypunching errors shall  be checked  by  the  contractor
prior to submission and all errors found by EPA in edit  checks  must be
corrected by the contractor.  All data rejected by EPA. shall  be cor-
rected and resubmitted by the contractor.   The  cost to perform  these
tasks shall be separately identified by the contractor.
     7.  The Project Officer shall specify if the  existing  state and
local data are to be updated or if a completely new inventory is to be
developed.
     8.  The area source emission inventory for TSP and  S02 shall  include,
in addition to annual estimates, estimates in tons per season as defined
below.
     a.  Winter - Dec., Jan., and Feb.
     b.  Spring - March, April, and May
     c.  Summer - June, July, and August
     d.  Fall   - Sept., Oct., and Nov.
     The contractor shall consult with the Project Officer  and  agree
on the sources of data to be used.  The contractor shall reference

-------
all sources of data used in development of the  plan  and work  through
the Project Officer in arranging  initial  contacts  for  sources of data.
     [References 2-10 can be used in compiling  and updating the
emission inventory.]
B.   Air Quality Data
     1.   Air quality data used in the data base shall  conform to the
requirements of 40 CFR 51.48.   For interstate areas, unless alternative
procedures are approved by the Project Officer, the  same  regional  air
quality baseline shall be used for analysis in  the constituent states.
     2.   Only data obtained in accordance with  monitoring methods  speci-
fied in 40 CFR 51.17a shall be used.
     3.   All air quality data used in the baseline which  has  not been
previously submitted to EPA will  be identified  in  accordance  with  the
forms specified in 40 CFR 51.7(a)(2).
     4.  The contractor shall  gather, review and evaluate air quality
data from all available sources,  including SAROAD, and State  and local
agencies, through Regional Office Aeros contacts.   The contractor shall
evaluate the data for:
         a.  Reliability - To determine if samples have been  collected
     and processed according to acceptable quality control practices.
     [See "Quality Control Practices in Processing Air Pollution Samples
     APTD 1132.]]1

-------
         b.  Suitability for calibrating dispersion models - The contrac-
     tor shall ensure that when possible the air quality data used are
     for the same baseline year as for the emission inventory and that
     all data are for the same year.   Substitute data may be used, if
     necessary, with the approval of the Project Officer.
         c.  Representativeness - The contractor shall obtain data for
     specific areas, including hot spots, background concentrations, and
     areas with the highest population density or total  population -
                                                                           1?
     [see page 31 of Volume 11, "Air Quality Monitoring  and Data Analysis".   ]
     5.  To ensure that air quality data used are representative of the
area, the contractor shall, as required by the Project Officer,  review
monitoring methods and site characteristics, including distances from
major pollutant sources and the location of the instrument probe,  its
height above ground, and distance from surfaces and minor sources  includ-
ing chimneys, incineration flues, laboratory hood vents, etc.   Only data
obtained by acceptable monitoring methods and instruments which  are cor-
rectly sited, shall  be used.   [Siting guidelines are shown on  pages 25-
32 of reference 13 and acceptable measuring methods are  described  on
page 31 of Volume II.12]
     6.  When data for averaging times specified in the  NAAQS  are  not
available, the contractor shall estimate concentrations  using  Larsen's
statistical methods  as detailed in AP-89.
     7.  The contractor shall  point out any deficiencies in the  air
quality data or in the procedures for acquiring reliable, accurate air
quality data to the Project Officer 1n the appropriate progress  reports
together with suggestions for  specific corrective actions.

-------
     8.  The contractor shall,  at the discretion  of the  Project  Officer,
analyze air quality for the base year with regard to correlations with
specific sources or classes of  sources,  and meteorology.
     [References 16 through 19  may be used in  compiling  a  complete  air
quality data base.]
C.   Meteorology
     1.  The contractor shall collect meteorological  data  for the area  of
interest for the purpose of applying dispersion models,  for identifying
the frequency and duration of meteorological conditions  affecting short
term high concentration levels, and for  estimating emissions  from space
heating.
     2.  For the purpose of accurately calibrating models,  the contrac-
tor shall ensure that when possible the  meteorological data used are  for
the same baseline year as for the emission inventory and air  quality  data.
     3.  The contractor shall use data from the National Climatic Center
(NCC) in Asheville, N.C. for wind speed, wind  direction  and atmospheric
stability, temperature and pressure, cloud cover, ceiling  height, and
degree days, unless it is clearly inappropriate or more  reliable data
collected by State and local  air pollution control  agencies,  meteoro-
logical data centers, airports, or local weather  stations  are available.
[Other sources of data are:

     shop Volume I - Manual  also discusses,  on  pages  30-36, meteoro-
     logical data needed to establish a complete  data  base.]
IV.  EMISSION PROJECTIONS
     1.  For the purpose of estimating emissions  in future years,
unless otherwise specified by the Project Officer,  the contractor
shall use the most detailed and accurate procedures (Level 3 in Volume
7,2 and Order 3 in Volume 1323) in accordance with  40  CFR  51.44,  51.45  and
51.49.  The contractor shall estimate future  activity  levels,  assuming
most probable growth, and project baseline emissions for at  least 20 years,
or if specified by the Project Officer, for lesser  periods to  conform to
the requirements of 40 CFR 51.51.
     2.  The contractor shall identify sources of growth projections, as
well as the parameters used in projections, in accordance  with 40 CFR
51.47.
     3.  The contractor shall demonstrate that emission projections are
consistent with activity levels used by agencies  responsible for  planning
under the following programs, as specified in 40  CFR 51.58:
     a.  The Federal Highway Administration (FWHA)  Act of  1962  (as
         amended) and the Urban Mass Transportation Act of 1964 (as

ti ons.
     5.  The contractor shall submit summaries of emissions  projections
for the tenth year following the date of the Administrator's identifica-
tion of the area, for at least one Intermediate year, and for the end of
the analysis period 1n accordance with the requirements  and  format given
in 40 CFR 51.51.
     6.  With the approval of the Project Officer, OBERS24 growth
projections may be used wherever local growth data are not available.
     7.  In projecting emissions, the contractor shall consider any
plans for fuel switching under the Energy Supply and Environmental
Coordination Act of 1974 (ESECA),25 and recommend fuel switching, where
possible.
                                 8

-------
     8.  For projection of emissions, the contractor shall coordinate
with appropriate State and local air pollution control and planning
agencies to obtain and project expected growth patterns for 20 years,
or a period of time compatible with the plans of other agencies in the
same area, as agreed to by the Project Officer.
     9.  Traffic data for modeling HC, CO, and NOV emissions shall be
                                                 A
obtained from the State Departments of Transportation, the State High-
way Administration or other appropriate organization.
     10.  The contractor shall consult with the Project Officer and

V.   EMISSION ALLOCATIONS
     1.  The contractor, for the base year and for all  projection  years,
shall allocate projected emissions for all categories  of emission
sources given in the errission inventory above, in conformance  with 40
CFP. 51.45, 51.49, and 51.51, as  directed by the Project Officer.   The
                                                           27    2"?
contractor shall apply the procedures detailed in Volumes 8  , 13    and
                           2P
the supplement to Volume 13   to the extent that they  are appropriate  and
within the resources available,  as determined in consultation  with the
Project Officer.
     2.  The contractor shall develop and submit a master grid and map of
                                            23
emissions for each pollutant using Volume 13   (pages  133-139) as  speci-
fied in Section 51.51(b).   Grid  sizes shall be 1km minimum as  recommended
in Volume 13.  Generally the maximum grid size should  be 8km for urban areas,
but may be larger for rural areas.
     3.  The master grid system  used shall be suitable for input to any
point and area source dispersion models to be used in  relating emissions
and air quality.
     4.  All distribution functions used in the emission allocation pro-
cedures shall be clearly identified.
     5.  The contractor shall summarize emissions allocations  for  the
tenth year following the Administrator's identification of the area, for
the intermediate year chosen in  IV(5) above for projected emissions, and
for the end of the applicable analysis period, to conform to the  require-
ment and format given in 40 CFR  51.51.
VI.  MODELING
     1.  The contractor shall employ the models and procedures given in
Volume 12 as specified in 40 CFR 51.46.
                               10

-------
     2.  The contractor shall present projected ambient  air  quality
concentrations in tabulations and isopleth maps with  a narrative
interpretation for each pollutant for the target years under study con-
sistent with the requirements of 40 CFR 51.51.
                                                   ??
     3.  Models other than those listed in Volume 12   may be used if
they are shown to be appropriate and approval  is obtained from the
Project Officer.
     4.  Multi-source models  shall  be validated and calibrated by the
contractor if sufficient data, such as the latest full year  of air
quality data from SAROAD, or  suitable data from State and local air
pollution control agencies, are available.  The Project  Officer will
specify the method to be used for calibration.   Once  a model  is cali-
brated, each application of the model thereafter must make use of a
data base similar to that on  which  the calibration was based.
     5.  For those pollutants modeled with AQDN, a source-receptor file
(culpability list) as shown on pages 130 and 133 of the  Workshop Manual
shall be developed as directed by the Project  Officer who will  specify
the configuration of the matrix.
     6.  Both short term and  annual concentrations shall  be  estimated
for the projection years.  Maximum short term  concentrations  shall be
determined both from major isolated point sources and major  aggregations
of point sources.
     7.  In predicting future air quality, the contractor shall use
meteorological data in the models which are representative of historical
conditions, considering worst, average and latest years'  data in
                                 11

-------
consultation with the Project Officer.   The contractor shall  use  data
which represent the same meteorological  conditions  in  the  projection
years as in the baseline year.
     8.  Normally, emission rates used in the models shall  assume maximum
production capacity and compliance with  regulations.   In the  case of known
problem sources, expected rates may be used with  adequate  justification.
     9.  HC reductions shall generally be assumed to be proportional to
VMT reductions, modified as necessary to reflect  local  conditions, e.g.,
characteristics of the meteorology, traffic and vehicle age distribution.
                                            22
     10.  Only models described in Volume 12   as being appropriate to
relate HC emissions to Ox concentrations shall be used, except  that
relationships based on local data shall  be used where  available,  with
the approval of the Project Officer.
     11.  As new guidance becomes available, the  contractor shall
employ 1t at the direction of the Project Officer.  Upon approval of
the Project Officer, the contractor shall make any  necessary  adjust-
ments to the model or to the data base in order to  accomodate any pecu-
liar situations, such as exceptionally adverse meteorological  or  topo-
graphical conditions in the area under study.
VII. ANALYSIS OF MODELING RESULTS
     1.  The contractor shall conduct an analysis of the modeling
results 1n accordance with 40 CFR 51.50.
     2.  In accounting for factors which affect the accuracy  of projected
concentrations the contractor shall consider, as  specified by the Pro-
ject Officer, the following:
                                 12

-------
a)  The degree of completion of abatement activities for which
regulations currently exist;
b)  Current air quality concentrations, the magnitude of past
year-to-year variations in air quality concentrations,  and the
degree to which the national standard is currently being violated;
c)  The future date when currently applicable measures  will  no
longer be able to ensure maintenance of national  standards;
d)  The stringency and comprehensiveness of existing regulations;
e)  The adequacy of the existing emission inventory;
f)  The adequacy of the current air quality surveillance pro-
cedures and enforcement activities;
g)  The adequacy of the current new source review procedures;
h)  The degree of confidence in the projected demographic and
economic data that was used to project emissions;
1)  The degree of confidence in the methods used  to project
emissions, allocate projected emissions and determine the air quality
concentrations resulting from the projected emissions;
j) Local and regional  meteorological  and topographical  condi-
tions ;
k) The frequency and severity of air pollution episodes since
the adoption of the existing implementation plan;
1) Progress made in reducing pollutant concentrations in the
last three years;
                            13

-------
     m) The adequacy of the manpower and financial  resources that the
     State will  obtain to implement current  and future  regulations and
     the growth  of the control  program since the adoption  of the existing
     plan.
     3.  The analysis of modeling results shall, at the option of the
project officer, also include  the following:
     a)  Relationship of calculated concentrations  to both primary and
     secondary standards, as well as year to year variations in measured
     air quality and frequency of air pollution episodes to determine the
     magnitude of the air quality problem.
     b)  Geographical extent of the problem, to distinguish widespread
     problems from those of a  local nature and presence of "hot spots" to
     determine the need for special application of  strategies.
     c)  Boundary problems, to determine if  violations  inside the
     study area are causing air quality problems outside the area, or vice
     versa.  In  interstate areas, the compatibility of  each State's strategy
     shall be considered.
     d)  The variation of the  problem with time, whether it is both
     an attainment and maintenance problem or either one alone in order
     that suitable strategies  can be chosen.
     4.  When models with a source-receptor  file are used, the contrac-
tor shall present a summary of the emission  reductions  needed to meet
the standards at each receptor and a tabulation of the  percent of total
concentration contributed by each source.  [As illustrated on pages 156
and 157 of the Air Quality Analysis Workshop Manual, Volume I. ]
                                 14

-------
     5.  If the modeling results  indicate  that there is no need for
an AQKP or other SIP revision,  the  contractor shall make an analysis of
all work performed, document  it in  a  form  suitable for review and
recording, and present a final  report in which such conclusions are
fully supported.
VIII. STRATEGY SELECTION, TESTING AND EVALUATION
     1.  The contractor shall discuss available strategies with the
Project Officer, develop a priority list of  strategies and select
those which may be applicable to  the  problems in the study area,
including use of all achievable technological controls, existing
source retrofit, fugitive dust  controls, increased enforcement, and
land use planning measures.  Consideration shall be given, but not limited
to the following, as appropriate:
     a)  Emission density zoning, a regulatory system in which the
     maximum legal rate of emissions  of air  pollutants from any given land
     area is limited by the size  of the area and its zoning classification.
     b)  Emission allocations,  a  regulatory  system in which the maxi-
     mum legal rate of emissions  of air pollutants from any given political
     jurisdiction or other area is  assigned  by an allocation procedure,
     and suitable sanctions,  such as  a construction ban, are imposed if an
     area uses up its allocation.
     c)  Transportation controls, including  encouragement of mass
     transit, and measures discussed  in the  November 6, 1973 Preamble to
     State Implementation Plan  Transportation Controls (38 FR 30626).
                                 15

-------
d)  A methodology for controlling proposed new  or  modified  buildings,
structures, facilities, or installations,  including municipal waste
water treatment facilities, that induce  or otherwise permit the  develop-
ment of other land uses and vehicular traffic that emit  air pollutants
for which there are national  standards.
e)  Fuel and energy conservation measures.
f)  Regulatory and other types  of measures to limit and  guide the
development of area, point, and line sources, including  measures such
as zoning and subdivision regulations, sewer and water connection  bans,
rezoning and building moratoria, capital  improvement programming,  and
open space reservations.
g)  Revision of local or regional development plans, and legal
mechanisms to prevent any development not  in accordance  with the plans.
h)  More restrictive emission controls and new  source performance
standards.
1)  Progressive phase-out of central power plants  and their replace-
ment by remote plants wherever  the change  would not significant  de-
grade air quality in the remote areas.
j) Greater use of district heating.
k) Fuel conversion such as coal gasification.
1) Phase-out of all on-site refuse incinerators.
m) Phase-out of inefficient oil burners.
n) Application of emission charges.
o) Tighter control over construction activities,  including  grading
and burning.
                            16

-------
     p) Regulations affecting the timing or spatial  location  of emissions.
     q) Specification of special operating conditions.
     2.  After it has been determined which measures  and  strategies
are technically adequate, the contractor shall  screen them  using criteria
which include the scope of the problem, availability  and  accuracy of  data,
social, institutional, and resource constraints and economic  considerations.
     3.  For those strategies which have been  selected, projected emissions
shall be modeled and resulting concentrations  compared to the standards.
If air quality projections indicate that NAAQS  will not be  attained and
maintained with these strategies, the contractor shall simulate the effect
of additional control measures, designated by  the Project Officer, on
emissions.  The contractor shall perform additional modeling  runs  to  deter-
mine the effect of these measures.  The contractor shall  negotiate any
additional costs with the Contracts Office before performing  additional
modeling.
     A.   Those strategies which are found to meet attainment/maintenance
requirements of the study area will then be analyzed to determine which
are the most suitable based on an evaluation of their social,  institutional,
economic and energy impacts, and public acceptability.  Weights  shall be
assigned to each of the strategies, in consultation with  Regional Office,
State and local officials, and the strategy sets  shall then be  ranked 1n
order.   The weighting and ranking of the strategies shall be  performed by
one or more of the following procedures, unless otherwise specified by the
Project Officer:
                                 17

     5.   The contractor shall  determine  if the  recommended strategies are
compatible with the  plans of all concerned State  and local agencies, in-
cluding  those agencies listed in 40  CFR  51.58(b).  The  contractor shall
obtain (or review) such plans  (including those  of agencies listed in 40
CFR 51.58(b)), and recommend any changes in  the air strategies necessary
for compatibility.  The contractor,  after consultation with the Project
Officer, shall also  recommend to the other non-air agencies involved
(including those listed in  40  CFR 51.58(b))  any changes needed in their
plans in order to ensure attainment  and  maintenance of the NAAQS.
     6.   The contractor shall  discuss  any strategy changes with the Project
Officer and State and  local  agencies,  and if any  significant changes are
made the contractor  shall retest the strategies,  through modeling, to
ensure attainment and  maintenance of the NAAQS.   The contractor shall
negotiate any additional costs with  the  Contracts Office before per-
forming these tasks.
     7.   Those strategies which  appear most  feasible for implementation,
based on the analysis  made  in VIII  2,  3, 4 and  5  above, shall be  identified
for use in the SIP revision, with a brief discussion of reasons why
these strategies are preferred.
                                 18

-------
IX.  PREPARATION OF Sit REVISIONS
A.   After the preferred strategies  have  been  selected,  evaluated, and
approved by the Project Officer, the contractor  shall  develop the SIP
revisions for attainment and/or maintenance, including legally enforce-
able regulations, while continuously consulting  with State and local
agencies including those listed in 40 CFR 51.58  and the  Project Officer.
The contractor shall submit the following items:

cified in 40 CFR § 51.44, S 51.45 and S 51.46.   This will include sum-
maries of the computations, assumptions and judgments  used in deter-
mining the emission reductions which will  be attained  through application
of the control strategies.  It would also include tabular and graphic
