To The Reader:
    I am delighted to provide you with the Final Report on the Ashtabula.  Ohio Geographic
Information Systems Demonstration Project. This project was designed and requested by Senior
Staff of Region V as a basis, in part, for bringing GIS technology  to the Region. The Final
Report serves  as  a "primer" on GIS capabilities for future reference by program staff.  In
addition, the Final Report integrates and analyzes data from many different U.S. EPA programs.

    The publication of this report marks the end of the successful demonstration phase for GIS
technology in Region V, and indeed the Geographic Information Systems Management Office
has been performing analyses and providing products to the programs for the past year. My staff,
in the GIS Management Office, looks forward to productive cooperation with the program staffs
on future projects, especially projects that will use  GIS to  facilitate environmental decision-
making in the programs.

                   EXECUTIVE SUMMARY

Environmental management of a defined geographic area such as
a National Priority List  (NPL) Superfund site or a Great Lakes
Area of Concern  (AOC)  must utilize data from many different
sources.  A Geographic Information System (CIS)  is the best
available  technology   for  managing   these   myriad  data.
Pollutants can be  discharged to the area in surface water,
ground water, air  or on  land.   soil types largely determine
the possible  spread  of contamination in  ground water  or as
airborne particulates.   Hydrography determines the potential
dissemination of contaminants in  surface water.    Land use
defines the potential exposure of the human population to the
pollutants.  The proximity of schools, homes for the elderly
and  drinking  water  supply  sources is  important  to  the
estimation  of   human   health   risk  associated   with  the
pollutants.  A CIS  can manage, spatially  relate, integrate and
analyze all of these data.

The purpose of this CIS demonstration project was as follows:
(1)  to demonstrate  GIS  capabilities  to  Region   5  program
offices dealing  with many different media;  (2)  to provide a
set  of  data layers   that  could  be used   for  the  future
management of  the Ashtabula  Area  of Concern  (AOC)  and the
Fields Brook National Priority List Superfund site;  and  (3) to
provide a  training exercise  for the newly  established GIS
Management Office  in Region 5 of the U.S. EPA.  This project
did not attempt  to analyze all  of  the  available  data  for a
specific goal,  such as  the  clean-up of a  Superfund  site.
Rather, data from many  different  sources,  and different types
of  analyses  were  chosen  to specifically meet  these goals.
Future applications of GIS technology for management of the
Superfund site or AOC would require that the Remedial Program
Manager of  the  Superfund  site  or  the  Remedial Action Plan
Coordinator of the AOC would guide  more comprehensive data
collection and analyses.  However,  these site managers could
use all of the work performed for this demonstration project,
and the now well  developed capabilities  of the GIS Management
Office as the basis  for  the comprehensive management of the
Superfund site and the Area of Concern.
                                               *
The Plan of  Study  (EPA 1989)  for this demonstration project
included the Multi-media Environmental Actions Tracking System
(MEATS).   As noted in the Plan of  Study,  the  inclusion of
MEATS  was  dependent on  additional  funding and the "beta-
testing" of MEATS  by non-GIS personnel.   Attempts to secure
additional funding were unsuccessful and therefore MEATS was
not included in this Final Report.

-------
This  Final  Report was  designed  to  serve  the  following
functions: (1) to  document the results of  the  Ashtabula CIS
Demonstration Project; (2)  to  serve as an introduction to EPA
managers of CIS capabilities;  and (3)  to  provide examples of
specific CIS analyses  and display methods, that  can be used as
a reference guide by CIS "clients"; therefore, some discussion
of basic CIS  concepts and terminology is included in the text.

                           INTRODUCTION
Geographic Information Systems

     Geographic Information Systems provide  data  entry,  storage,
     manipulation,   analysis    and   display   capabilities   for
     geographic, environmental, cultural, statistical and political
     data in a common spatial  framework.  The data analyzed are a
     collection  of  spatial information (represented by  points,
     lines and polygons) and their associated tabular and spatial
     attributes (characteristics of the  features which the points,
     lines and polygons represent). The  attributes associated with
     these spatial data may include ownership information, chemical
     characteristics or land use activities.   Sources of data for
     GISs  include maps,  aerial  photographs,  satellite  images,
     census data, field measurements, etc.   These  data  may be in
     digital format or on paper.  GISs are fully integrated systems
     that analyze and  map spatial data and provide  graphic  and
     tabular products.   CIS technology bridges the disciplines of
     geography,   computer   science,    information   management,
     cartography,   environmental   science   and   environmental
     management.  The  GIS is  distinguished from  other  computer
     systems by its ability to perform spatial analyses.  A GIS has
     five major  components  as follows:    (1)  Hardware -  used to
     store, process and display  digital map  data;  (2)  Software -
     performs  GIS  operations;  (3) Digital Map Data  - which is
     manipulated with the GIS; (4) Procedures - followed to perform
     various operations; and (5) Expertise - the people who provide
     the intelligence to use the system.   While not strictly a part
     of a GIS, a 6th  component  is  necessary for the successful use
     of GIS  by the  EPA  - people in  media specific  programs to
     design projects and formulate hypotheses to  be tested using
     GIS.
Ashtabula Area of Concern

     The City  of Ashtabula is  in  Ashtabula County, Ohio  on  the
     shore of Lake Erie.   The Ashtabula River near its entrance to
     Lake Erie has been contaminated with heavy metals, chlorinated
     organic  compounds,   PCBs  and  oxygen  consuming  pollutants.
     Eighteen  industries  and  one  wastewater  treatment  plant
     discharge to the Area of Concern  (AOC)  as designated by  the
     International Joint  Commission of Canada and the United States
     (IJC).  Fish consumption advisories for the  lower  river  and
     Ashtabula  harbor  have been issued due  to  PCBs and  toxic
     organic chemicals in fish  tissue.  Ground water near Fields
     Brook and the lower Ashtabula River  has been contaminated by
     past disposal practices  and landfills.   Clearly the ground
     water,  surface  water and  sediments of the  lower  Ashtabula
     River may pose a substantial health risk to the local populace

-------
     and may be impairing ecosystem function.  Several different
     approaches to the clean-up of the lower  Ashtabula River are
     simultaneously occurring.   The U.S.  EPA  Superfund Program is
     concentrating on Fields Brook, the state of Ohio is developing
     a Remedial Action Plan for the AOC, U.S. EPA's NPDES permit
     process  has   improved  the  quality  of  the  effluent  that
     continues  to  be discharged,  and  the  U.S.  Army  Corp  of
     Engineers (COE) proposes to dredge some contaminated sediments
     from Ashtabula Harbor.
Fields Brook National Priority List Superfund Site

     Fields Brook, a tributary to the lower Ashtabula River,  is a
     Superfund site  due primarily  to  sediments contaminated by
     toxic pollutants.   The contaminants  include  chlorobenzene;
     l ,1, l-trichloroethane;     l, 1, 2-trichloroethane;    1,1-
     dichloroethene;  tetrachloroethene;   trichloroethene;  vinyl
     chloride;    hexachloroethane;    hexachlorobutadiene;
     toluenediamine; toluene diisocyanate; 1,2,4-trichlorobenzene;
     hexachlobenzene;  PCBs; zinc;  mercury;  lead;  chromium and
     titanium.  Because of the possibility of direct contact  with
     the sediment, movement of the contaminated sediment  into the
     Ashtabula  River   and  Lake  Erie,   possible  movement  of
     contaminants  into the public  water supply of the City of
     Ashtabula, and  the possibility of uncontrolled releases of
     hazardous materials from  the sediment, the site was  included
     on the National Priority  List of Superfund sites.
                           DATA LAYERS

     One  way to  organize data  in a  CIS is  as  thematic  "data
     layers".  These data layers can be thought of as a series of
     transparent map overlays, each for a  specific feature such as
     streams, roads, wells or soils.

                         — CIS FYI 	
          A  data  layer is a  digital  representation  of
          spatial and tabular information.  In ARC/INFO,
          tne  Agency  standard  GIS,  data  layers  are
          referred  to  as 'coverages'.   For  example,  a
          point  coverage  of  Toxic  Release  inventory
          (TRI) facilities may  include a  map with each
          facility  represented  by a point and a  table
          for eacn  facility witft the amount of chemical
          pollutants  reported.    This  coverage  vouid
          allow the mapping  of  all facilities with a
          specific  discharge of a particular pollutant.

-------
                        FIGURES

The spatial information from data layers can be displayed on
'maps' either by itself or combined and integrated with other
data layers.  The  data features  are  characterized as points
(single  locations),  lines   (multiple  locations  which  are
topologically consistent),  polygons  (areas of  homogeneous
features) , annotation  (graphic text) , or combinations of the
above.  The tabular or attribute information in relation to
the spatial information is used to graphically delineate and
symbolize data features.  All figures are in numerical order
at  the end  of  the  text.    These figures  consist  of  maps
produced at two different scales, each appropriate  to  the data
being  displayed.    The  large scale  maps,  at a scale  of
1:29,230, are limited by the boundaries of the Ashtabula AOC
(Ohio  EPA  1990).   The latitude  and longitude  (degrees  and
minutes) are indicated on the edges of the AOC boundary.  The
small  scale maps,  at  a scale of  1:315,590,  encompass all of
Ashtabula County and  parts of  adjacent  counties in Ohio and
Pennsylvania. This scale permits the  mapping of features that
extend beyond the AOC boundary.
     With the  ARC/INFO software, the  GIS* Analyst
     has the ability to display data, with reference
     to   geography,   data  scale   and   feature
     delineation.   Maps   and   features  can   ;be
     presented  at  any physical  size, with  many
     colors  and  many  customized  user-generated
     symbols.  Examples in  the Ashtabula  project
     display only a few of these capabilities,
                    DATA DICTIONARY

The  importance of  maintaining  a  data  dictionary or  data
documentation is critical to any CIS  project.    The general
goal  of  data  documentation  is  to  provide  reviewers  and
potential users a history of the data and a means to determine
the viability and integrity of  the  data.   Constructive data
documentation   persists   despite   system,   personnel   and
administrative changes. The  most critical elements  of data
layer  description,  data layer  source information  and data
layer quality information have been included in this report.
The Data Dictionary  for each coverage is in alphabetical order
at the end of the text.

-------
                         	 GIS FYI 	
          For the Ashtabula project several specialised
          programs  were  developed to  input,  update,
          display and query (51S data documentation.  The
          data layer description provides an explanation
          of the  data,  its type and areal  extent.  The
          data  layer  source information indicates  the
          original source  of the  data  (reports,  maps,
          offices, conversations  etc.), original  data
          scale and dates of the source and automation,
          The  data  layer  quality  information  is  a
          subjective but  important account by the  GIS
          Analyst  of   the  accuracy,  integrity   and
          reliability of the data.
                   CIS DESCRIPTION AND ANALYSIS
                 OF THE ASHTABULA AREA OF CONCERN
Hydrography
     Hydrography describes the location and direction of flow (if
     any) of surface waters.  Many different maps of the AOC show
     portions of the Ashtabula River or Fields Brook.  Digital data
     are  available  at  two different  scales,  1:2,000,000  and
     1:100,000 from  the  USGS as  Digital Line Graphs (DLGs).   The
     1:2M data  are too  coarse for  this  large  scale study.   The
     l:100K hydrography  data provide  the  Lake  Erie shoreline and
     the Ashtabula River in Figure 1 and the baseline hydrography
     in many of the other figures.   Paper maps for the AOC provide
     larger scale hydrography with greater detail than the 1:100K
     DLGs.   Hydrography from four  different sources  (USGS 1978;
     USGS 1979; CH2M HILL 1987; Woodward-Clyde 1990) was digitized
     and combined  in Figure 1, to provide a spatial definition of
     the  hydrography  of the AOC  far superior  to any previous
     document.  Figure 1.1 provides some of the details about the
     types of features mapped on Figure 1.  The reader  interested
     in details of features  and  data  sources should refer to the
     Data Dictionary for a description of  each coverage  named on a
     figure.

                         	 GIS FYI 	
          Figure 1 provides an example of a combination
          arc and polygon coverage.  It also demonstrates
          the ability of GIS to integrate data by simply
          overlaying data  from different  sources.   The
          ecoregion coverage (Figure 2)  is an example of
          data sharing between different offices within
          EPA.

-------
Ecoregions and Soils

     A map  of the  ecoregions of  the Upper  Midwest States  was
     compiled by the USEPA Environmental Research Lab in Corvallis
     (Omernik and Gallant 1988).   The ecoregions  represent areas
     that are relatively homogeneous in patterns of combinations of
     factors  including land  use,   land-surface  form,  potential
     natural vegetation and soils.  Figure 2 indicates that the AOC
     is  all   in  one  ecoregion  according  to   the   Corvallis
     delineation.  By  comparing Figure 3,  the detailed  Soils map
     for Ashtabula County (USDA 1973), with Figure 2,  it becomes
     apparent that the soils in the AOC are far  from homogeneous.
     Clearly the data collected for these two maps were designed to
     address very different goals.   The data that are appropriate
     to use  for  decision-making  are dependent  on the  specific
     question being asked.

                         	 GIS FYI 	
          Figures 2  and  3 provide examples of  polygon
          coverages.    These  figures   highlight  tne
          importance  of   study  design  prior  to  data
          collection.   Further,  when  using  existing
          data, icnowiedge of  the scale and purpose of
          those    data   is   mandatory   for    data
          interpretation,


Ownership

     Land ownership is dynamic.  The ownership shown in Figure 4 is
     the result of an aerial photo interpretation (EMSL-LV 1985).
     If the  goal of  a project  were  to  create  a series  of  maps
     showing historical land ownership, GIS would  be  the perfect
     tool for the job.

                          	GIS FYI	
          A GIS can utilize data from many sources that
          already exist in  EPA,  such as  aerial  photos
          and remote sensing data from EMSL and EPIC*

-------
Transportation

     Roads,  railroads  and pipelines  (Figures 5  and  6)  provide
     references for locating other map features.   They also allow
     the potential analysis of risk associated the accidental spill
     of  materials  in transport.   These figures  (5  and  6)  were
     produced from digital data purchased from the U.S. Geological
     Survey  (USGS).

                          	GIS FYI<	
          Digital Line Graphs (DLGS) are available from
          tne  tfSGS  at   several   different  scales   -
          1:2,000,000;    1:250,000;    1;100,000;    and
          1:24/000,  Many different data are available *-
          hydrography,  transportation,  census  tracts,
          etc.   However,  availability of these  data
          nationally Is very Incomplete.
Land Use

     A description of the land use in a defined geographic area may
     serve many  functions.   A crude  risk analysis  could use the
     land use in Figure 7 to determine the proximity of residential
     areas to industrial areas.  However,  as with all data, the
     source and scale must be considered.  The data used to produce
     Figure  7  were  from 1973 and  were produced  at a  scale  of
     1:250,000.  These data are  old and perhaps too coarse for a
     detailed risk assessment in the AOC.
          These   land  use   data  are  from  the  USGS
          Geographic information Retrieval and Analysis
          System  (GI&&S) , another source of digital data
          from a  federal agency.
Ownership and  "Made Land"

     On  Figure 3,  the classification "Ma" indicates "made  land".
     Made land consists of areas of earth fill, of borrow pits, and
     of  areas where much of the soil surface is covered by streets,
     homes,  factories  or docks.    in  all of these areas,  the
     original   soils   have  been  greatly   altered  (USDA  Soil
     Conservation Service 1973).  An immediate question that  arises
     is  -  who  made that  land?  By  combining soils and ownership
     data  into Figure  8,  it becomes  apparent that some  of the
     industrial  owners  occupy  a  large  percentage of  the "made
     land".   This analysis starts the  complete inquiry into the
     question  of who  made  that land.

-------
                          	GIS FYI	
          None of the data  used for the analysis shown
          in Figure  8 came  in digital format.   Paper
          maps were manually  digitized on a digitizing
          tablet and  attributes were  assigned  to each
          polygon!by the analyst.
Schools and Hospitals

     Part  of a  risk  assessment  is  determining the  population
     exposed.  Children,  the elderly  and  the ill are  high risk
     populations for some types of  exposure.   Figure  9  shows the
     location of schools, hospitals,  day care centers and senior
     care facilities in the Ashtabula AOC.
          The location of points, such as schools, on a
          map is only part of: a Gis coverage.  The other
          part is: a  database  that contains information
          about the point.  For the school coverage, the
          database  contains  enrollment  figures*  that
          would allow the GIS analyst  to interactively
          identify a school and the GIS  would respond
          with the enrollment data.
Drinking Water Supply

     The proximity of  drinking  water  supply  sources  to pollutant
     dischargers  or   in-place   contaminants  is  important   in
     determining  the  pathway  of  exposure  in  risk  assessment.
     Figures 10 and  11  show  the drinking  water  supply sources in
     the AOC and in Ashtabula County.

                          	GIS FYI	
          These data  are from  EPA's  Federal Reporting
          Data system (FRDS)*  AH databases maintained
          by the  EPA  should strive to contain  actual
          locationai coordinates for the facility, wen,
          stack, etc, which is being described.   County
          or zip  code  centroids  are  not  adequate and
          Global  Positioning   Systems   (GPSs)   should
          become  part  of  the  tool kit  of  all  field
          personnel collecting  data to be entered into
          any EPA database.

Zip Codes
     The zip code areas in Ashtabula County are shown in Figure 12.
     These can be used as a cross-reference with the county name or
     locational  coordinates to provide a Quality Assurance check on
     the locational coordinates.

                          	GIS  FYI	
          This  zip code  coverage was purchased from  a
          private  vendor.     There  are  many  vendors
          creating digital data for use with <3i$s*  In
          addition to off-the-shelf data, many  vendors
          will  create custom coverages*   These services
          are  expensive,  but they  do  provide   Mgh
          quality data and relatively short  turn-around
          times when contract money is in greater supply
          than
Pollution Dischargers

     Figure  13  shows the  location of  municipal and  industrial
     dischargers in the AOC.   It also shows the  location  of the
     STORET  sampling  stations  in  the  AOC.    'with  the  high
     concentration of dischargers in the AOC,  perhaps more STORET
     sampling stations should be monitoring water quality.

                          	GIS FYI	
          The  ability  of  GIS  to  perform  a  quality
          assurance check  on  locational  data is  also
          shown in Figure 13.  The Cleveland Electrical
          Co.  (CLEVE  ELEC)  is actually located  on  the
          shore of Lake Erie, but the Permit Compliance
          System (PCS) data  places  it  in  the southeast
          corner of the AOC*  This error  was  apparent
          only  because of   the  ability  of a  GIS  to
          integrate  and compare  data  from  different
          sources.

-------
Sediment and Effluent Sampling Stations

     Figure 14  shows  the location of the  sampling  stations used
     during the scoping effort on the Fields Brook NPL site (CH2M
     HILL 1987).  A comparison of  this figure with Figures 1 and 4
     indicates  that many of  the  surface  water  bodies  and land
     owners did not have sampling stations.

                          	CIS FYI	
          A GIB could help  design a sampling  network
          that  would  insure  adequate  sampling  near
          important features.  For example, a GIB could
          answer  -the  following cjuestions  (i) Are  all
          i&entified water bodies  being sampled? <2) Are
          all  property  owners being  sampled?  (3)  Are
          enough  samples  being  taken  near  sc&ools,
          hospitals, etc,


Air Monitoring

     As  seen  in Figure  15,  there are no  Aerometric  Information
     Reporting  System (AIRS) monitoring  stations  in the AOC,  and
     there are only two in Ashtabula County.

                          	CIS FYI	
          The integration of  data from  different media
          programs  is one of the main strengths of <3IS.
          If all  of the  air,  water,  sediment and biota
          sampling  stations  were overlaid  with  high
          priority  sites  (such  as  NPL  sites),  all
          programs   would    benefit    from   a   more
          comprehensive and  integrated sampling network.


Superfund Sites

     There are 46 Superfund  sites  (not all National Priority List,
     NPL, sites)  in Ashtabula County and 15 of those are in the
     AOC.   Figure  16 and  17 map all of these sites as points.
     Clearly,  many of  the  sites  have   the  same coordinates  in
     CERCLIS, the Superfund database; and many of the coordinates
     are incorrect.   In  CERCLIS,  the Fields  Brook NPL site is in
     Lake Erie.

                          	GIS FYI	
          When  errors in locationai data  are  found by
          Region 5 <3IS analysts, the error and often the
          correct   coordinates  are  reported  to  the
          appropriate database manager  for correction.
          Thus, all database  users benefit from the QA
          check performed by a CIS.

-------

RCRA Sites
     The RCRA  database  is  the Hazardous  Waste Data  Management
     System (HWDMS).  While HWDMS has fields defined for latitude
     and longitude, only 19 of 161 records for Ashtabula County had
     coordinate  values  in  those  fields.    Since  the  city  of
     Ashtabula  is  not  a Standard  Metropolitan Area   (SMA),  as
     defined by the  Bureau of  census,  coordinates  can not  be
     assigned to the addresses using TIGER files.  The RCRA program
     has  recognized  the  utility of  latitude  and  longitude  by
     including  fields in the national  database but clearly the
     reporting  of  coordinates  has not become mandatory  for RCRA
     facilities.  The addition of coordinates to HWDMS would make
     these data much more useful  in future analyses involving CIS.
Toxic Release Inventory (TRI)

     TRI  facilities in  the AOC  are mapped  in Figure  18.   In
     addition to a point representing the location of the facility,
     a  shaded  circle  around  each  facility  is  exponentially
     proportional  in size to the total amount of chemical release
     or transfer reported by that facility in 1988.

                          	GIS FYI	
          Figure   18  highlights  the  GIS  ability  to
          display  tabular  data  graphically.    Often  a
          graphic   display  of   data   receives   more
          attention than a table of numbers.
OA of TRI data

Since   this  demonstration   project  mapped   actual  ownership
boundaries, the locational errors in the  TRI  database  were readily
apparent  (Figure  19).   These errors  have been  reported  to the
national TRI database manager.

                                                               11

Buffer Zones Around Selected Features

     Places that people congregate should receive emphasis during
     a risk assessment.  Figure 20 displays 100 meter and 500 meter
     buffer zones around schools, hospitals, day care centers and
     senior care facilities.  Using this coverage and the sampling
     station coverage (Figure 14), the CIS analyst could determine
     how many sampling stations are within the buffer zones.  Or,
     using the buffer coverage and the TRI  release coverage (Figure
     18), the analyst could  determine  if  significant  releases of
     toxic chemicals had occurred in the buffer zones.


                          	GIS FYI—
          Analyses such, as suggested above, using  tne
          buffer  coverage,  are  relatively simple  GIS
          functions  once  the   coverages  are  built.
          However, GIS analysts  are  not  specialists in
          the Sally  functions  of EPA's media  programs
          and meaningful  analyses  must  be guided  by
          media program staff.
Triangulated Irregular Network (TIN)

     A TIN is a method of displaying three-dimensional data.  Since
     volumes are 3-D data, TIN can be used to analyze volume data
     also.  Figure 21 displays the population of Ohio as a TIN.

                          	GIS FYI	
          While TINs provide eye-catching displays, they
          are not always appropriate for the data to £e
          displayed.   For  example, should  population
          peaks be "smoothed" from county to county, or
          are population peaks really discreet "spikes"
          in only a  small portion of the  county?   The
          GIS  analyst  can help  media  program  staff
          choose  the   most  effective   and  accurate
          analysis and display of media program data.

Color vs. Black—and-White Figures

     Color graphics are easily produced by CIS and provide a more
     readily understood map with higher information content, as can
     be seen by comparing Figures 1,3 and 7 with Figures 22, 23 and
     24.    However,  the  production  and  reproduction  of  color
     graphics are expensive and most  reports  that will  be widely
     distributed  still depend  on  black-and-white  graphics  for
     economic reasons.   Large maps or  presentation  graphics are
     presently the most viable use for color graphics.   GISMO has
     been  trying  to  acquire  a color electrostatic plotter  for
     Region 5 which would make color graphics much more accessible.

                             SUMMARY
Demonstration Project Educational Value

     The primary  goals of this  project  were to  demonstrate  CIS
     capabilities to  Region  5 program offices  and to  provide  a
     training  exercise  for  the  newly  established  Geographic
     Information Systems Management Office  (GISMO).   These goals
     were more than  fulfilled by this project. Data were used from
     many different  sources  and in many different  formats;  many
     different analyses were performed; all of the major modules of
     the software were used;  and the basics of database design and
     documentation were  invoked.   In addition, contact  was  made
     with many media program staff and state personnel.

     The  utility  of  this project  to other offices  in EPA  is
     apparent  in  several  cases.    The  necessity  for  better
     coordinate  data  has  been  strongly  noted by  several  EPA
     database managers.  Several Remedial Program Managers (RPMs)
     are now acutely aware of the need to have CIS personnel  help
     design site plans for the  collection of  data.  These RPMs are
     now also insisting on electronic copies of data and reports
     from contractors, whereas  in the past only paper or microfilm
     copies were available.This final report was written to serve
     as an introduction to CIS  for media program staff.  The value
     of this report as a primer and reference on CIS capabilities
     will not  be known  until  after distribution.   We  hope  the
     readers will provide suggestions and comments.

     The  following  important  lessons  were  learned during  this
     demonstration project:

          (l) All CIS demonstration projects need a clear client to
          guide the study.

          (2)  Demonstration projects  need  clear,  well-defined
          modest goals. Each coverage should provide a stand-alone
          product or display of a CIS capability.

          (3)  EPA should insist that all contractors provide their
          reports and data to EPA in an electronic format. „

          (4)  Zip code and county  name  do  not  provide adequate
          locational data.

          (5) Street addresses are of little  value unless the site
          is  in  a Standard Metropolitan Area (SMA) for  which  a
          TIGER  file  is  available;  and  even  then  extracting
          coordinates  using  address-matching  is  a  painstaking
          process.

-------
14
          (6) AH field inspectors collecting data to be  used by
          EPA  need  to use  a GPS  as  part  of  their  routine
          inspection.

          (7) EPA needs to select a standard locational data format
          as much as EPA needs locational data accuracy standards.

          (8) EPA needs Arc/Info coverage documentation standards
          to   facilitate    coverage   sharing  and   to   prevent
          obsolescence of coverages.
Future Use of the Coverages Developed

     These  coverages  will  be used  to  help  evaluate the  field
     sampling conducted on the Fields Brook NPL site in the spring
     of  1990.   The future  management  of the  NPL site may  make
     extensive use of  these coverages and of CIS.  These coverages
     will  be exported  and  provided to  the  USEPA  Great  Lakes
     National Program Office and the State of Ohio for use in the
     management of the Ashtabula Area of Concern.  A future  risk
     assessment  of  the  Ashtabula  area  may  be  performed  in
     conjunction  with the  Office  of  Health  and  Environmental
     Assessment and a sponsoring program office.

     The  locational information front the AIRS site files are very good especially
     in comparison with other EPA databases. Thus far, it appears that the state
     agencies responsible for the sites are accurately recording the site
     coordinates.  In the SE Chicago/NW Indiana area, sites were located very
     accurately  ie. on the proper block and on the proper side of the street when
     compared to 1:100,800 converted DLG road data.

     Quality Report for  ASH-TRI88
     For the 1988 Toxic Release Inventory (TRI) database each reporting facility
     is required to supply latitude and longitude coordinates for the location of
     their facility. A quality assurance assessment of this data is difficult since
     it has not been previously integrated with other data. This layer represents
     only those points which have a Federal Information Processing Standard (FIPS)
     number equal to that for Ashtabula County, Ohio. When the data was referenced
     to -the Ashtabula county boundary several points mapped outside and beyond the
     boundary by as much as 122 kilometers.

     analysis report using a Calcomp 9100 series digitizer.  The scale of  the
     air photo was noted as 1:24,000 and could overlay perfectly with the
     corresponding 7.5 minute quadrangle map.  Tics used to orient the map were
     from the quadrangle maps.

     Quality Report for  SOILS

     The soil survey of Ashtabula County within the Ashtabula AOC boundary was d
     digitized on a Calcomp 9100 series digitizing table.  The minimum four tics
     used to orient the soil survey sheets were extracted from exact and known
     node coordinates (road intersections) of the 1:100,000 converted DLG data.
     RMS values during the automation averaged 0.010.  This high value is related
     to digitizing from the 'unstable' paper soil survey sheets.  A hardcopy plot
     was quality controlled and rectified with the soil survey sheets and 7.5
     minute quadrangle maps.

      Several maps from the Scoping Document were used.   RMS errors were consistently
      reported of 0.003 to 0.005 using tics located at nodes of road intersections
      or other stable  locations.  The raw digitized data was TRANSFORMed into the UTM
      meters coordinate system.
