                    The Process Model  Projection
                  Technique (PROMPT) is  one of four
                  stationary source emission  and
                  control  cost  forecasting models
                  developed  by the EPA for the
                  National Acid  Precipitation Assess-
                  ment  Program (NAPAP). PROMPT
                  projects  air pollution  emissions
                  (sulfur dioxide, sulfates and nitrogen
                  oxides) and costs for industrial
                  combustion and industrial processes
                  (i.e.,  process  heaters, furnaces,
                  dryers, kilns, engines, turbines and
                  wood-fired  boilers). PROMPT
                  excludes  the combustion of natural
                  gas, distillate or residual fuel oil and
                  coal in industrial boilers. The outputs
                  are provided for 1980 (baseline), 1985
                  (forecasted,  not actual), 1990,1995,
                  2000, 2010, 2020 and 2030.
                    This document is a user's manual
                  for Version  3.0  of  PROMPT.  It
                  includes procedures and options for
                  model operation on an IBM-AT or
                  compatible personal computer. The
                  model's operation  is menu  driven
                  and relatively easy to use.
                     This Project Summary was devel-
                  oped by EPA's Air  and Energy
                  Engineering  Research  Laboratory,
                  Research Triangle Park, NC,  to
                  announce  key findings  of the
                  research project that is  fully
                  documented in a separate report of
                  the same title (see Project Report
                  ordering information at back).

                  Purpose of PROMPT
                    The Process  Model Projection Tech-
                  nique (PROMPT) has been  developed by
 Energy and Environmental Analysis, Inc.
 for the U.S. Environmental Protection
 Agency (EPA) in cooperation with the
 National Acid  Precipitation  Assessment
 Program  (NAPAP).  By design, it is  a
 simple, low cost model which will provide
 an initial assessment of the role  and
 magnitude  of  industrial  process
 emissions in  the  control  of  acid
 deposition SOa. sulfate, and  NOX pre-
 cursors.
  PROMPT is  designed to  estimate
 future air emissions from industrial fuel
 combustion and industrial processes (i.e.,
 process heaters, furnaces, dryers, kilns,
 engines,  turbines  and  wood-fired
 boilers).  PROMPT excludes  the
 combustion of natural gas, distillate or
 residual fuel oil and coal in  industrial
 boilers. PROMPT produces  regional and
 state-level air emission  projections
 (S02, primary sulfates, and NOX)  and
 incremental air pollution control costs.
 The  outputs  are provided  for  1980
 (baseline), 1985 (forecasted, not actual),
 1990, 1995, 2000, 2010, 2020, and 2030.
 Overview of User Options
  PROMPT  produces industrial air
 pollutant  emissions forecasts  from
 energy use  projections generated by
 model runs of Version 2 of the Industrial
 Sector Technology Use Model  (ISTUM-
 2).
  PROMPT will operate on one of the
 four fuel demand scenarios specified by
 the model operator. Three  alternative
 scenarios are based on 1985 test cases
 produced  by Argonne National Labora-

-------
tory  for NAPAP. These  three available
cases are:

• NAPAP Low Fuel  Price/Economic
  Growth Rate
• NAPAP  1985 Reference  (Moderate)
  Fuel Price/Economic Growth Rate, and
• NAPAP  1985  High  Fuel  Price/
  Economic Growth Rate.

  The fourth case is based on the 1986
EEA  middle  oil price case  and  the
NAPAP 1985  Low  Economic Growth
Rate scenario. The  user may also  edit
these energy demand files.
  The emissions and control  cost
module  estimates controlled  NOX  and
SOj emissions  and  allows the user to
select alternative  air  pollution  control
strategies. The  user  may  edit  the
emission rates  and/or  pollution  control
costs.
  PROMPT will determine a  least-cost
solution for compliance with a selected
air  pollution   control  strategy  and
compute  the  resulting  emissions
reduction and incremental costs. When
specifying a control strategy, the user is
asked to choose:
• The type of control strategy (which can
  differ for  new  and existing sources),
  and
• The year of implementation (which can
  also differ  for  new  and existing
  sources)

  The control  strategy  alternatives in
PROMPT that  can  be applied to either
NOX or S02 emissions are:

• A flat emissions limit (all sources meet
  a specified limit in lb/106 Btu),
• A uniform percent reduction  (each
  emission  source  has  to  reduce
  uncontrolled  emissions by a specified
  percentage),
• A specified  cost-effectiveness (all
  control  technologies having a  cost-
  effectiveness of  control  less  than  a
  given  cost-effectiveness  ratio,  $/lb,
  are adopted), and
• An  aggregate  emissions reduction
  (total  uncontrolled emissions  are
  reduced by  a  specified amount per
  year or percentage, beginning with the
  most cost-effective, until  the  total
  reduction is reached).
  PROMPT will forecast S02 and sulfate
emissions or  it will  forecast NOX emis-
sions. It will not forecast emissions for all
three pollutants in the same run. The NO,
emissions forecasts  in PROMPT are nol
a function of sulfur emissions contro
strategies. Similarly,  S02  and sulfate
emissions forecasts  in PROMPT are noi
a function of NOX emissions  contro
strategies.
