2.0 Spatial Framework

The data collection effort for the representative national data set centers around the

collection of site-based data for a representative sample of 201 nonhazardous industrial waste

management facilities, along with the national and regional data necessary to complement this

site-based data set. The 3MRA modeling system uses site-based modeling to provide spatial

distributions of contaminants in a prespecified radius of interest around Industrial D facilities

with land-based WMUs. To support this strategy, the data collection effort included mapping the

modeled facilities nationally (using GIS), providing a spatial frame-of-reference around each

facility within the AOI for the analysis, and collecting site-based and regional data within this

framework. 

2.1 Modeled Sites

The 201 sites in the representative national data set are a random sample from EPA’s

1985 Screening Survey of Industrial Subtitle D Establishments (Westat, 1987), also referred to as

the Industrial D Screening Survey or Industrial D. This survey was designed to characterize

nonhazardous (RCRA Subtitle D) waste management practices for 17 industry groups and four

land-based WMU types: landfills, waste piles, LAUs, and surface impoundments. Data from this

survey have been used to represent Industrial D facility locations and WMU characteristics in a

variety of RCRA regulatory initiatives. Although the Industrial D data are more than 10 years

old, they represent the largest consistent set of data available on Industrial D WMU locations,

dimensions, and waste volumes. Information on the survey design, response rates, and overall

data quality and completeness may be found in Westat (1987), Clickner (1988), and Clickner and

Craig (1988).

The Industrial D screening survey contacted 15,844 industrial facilities. Of those, 2,850

reported that they managed waste in a landfill, LAU, surface impoundment, or waste pile. To

adequately represent the 17 industry groups, EPA randomly selected 201 sites from these 2,850

facilities (see Section 3.0 for more details on site selection). Appendix 2A at the end of this

section lists the 201 facilities by their industry group and shows the number of WMU types at

each facility. The basic assumption for this analysis is that these data are representative of the

types, characteristics, and locations of nonhazardous industrial WMUs.

2.2 Site Locations

The Industrial D Screening Survey contained only address and zip code locations for the

sampled facilities. Although zip code centroids were adequate for previous uses of the Industrial

D data, the site-based data collection for the 3MRA modeling system required more accurate

locations. Results of a pilot study showed that locational accuracy could have a great impact on

the data collected around a site, especially for population and land use data. Because zip code
Section 2.0 Spatial Framework

 1Because aerated tanks were not included in the Industrial D screening survey data, a tank is placed at every

Industrial D site with a surface impoundment (see Section 3); thus, every surface impoundment site has at least two

settings, surface impoundment and aerated tank.

centroid locations can be off by 2 km or more, facilities can be displaced from urban to rural

settings or vice versa.

Accuracy of the site location information was improved through a variety of techniques,

including the following:

# Matching facilities to EPA’s Location Reference Tables (LRT) from the

Envirofacts database to obtain the Agency’s most reliable location,

# Identifying zip code centroids using GIS software (for sites that could not be

matched to the LRT), and

# Visually placing sites using interactive ArcView software based on land use,

WMU features (e.g., large surface impoundments), and topographic maps (when

available).

Appendix 2A provides the best locations obtained for each of the 201 Industrial D

facilities. Appendix 2B describes the facility location effort in detail, including the source for

each location and the rationale for every manual site location adjustment. In essence, the effort

helped to ensure that all Industrial D locations used in the representative national data set are a

reasonable representation of current and future industrial nonhazardous waste management

facilities.

2.3 Settings and Area of Interest (AOI) 

Based on sensitivity analysis results for the Air Module, EPA has defined the AOI for the

representative national data set as the area encompassed by a circle defined by a 2 km radius

extending from the corner of a square WMU. Many Industrial D sites have multiple WMU types;

when this occurs, multiple AOIs and “settings” are defined. A setting is the basic modeling unit

for the 3MRA modeling system and is defined as each unique WMU type/site combination.

Thus, a site with a landfill and a waste pile would constitute two settings.

There are 419 unique site/WMU settings across the 201 sites selected for the

representative national data set. Each of these settings is modeled independently and all sitebased data are passed to the 3MRA modeling system with a unique setting identification number,

Setting_ID. The Setting_ID is simply the WMU type present in the Industrial D data1

 (landfill,

waste pile, LAU, surface impoundment, and/or aerated tank) plus the seven-digit Industrial D

Site ID. Thus, if Industrial D site 1234567 has a landfill and a waste pile present, it would have

two settings: LF1234567 and WP1234567. Appendix 2A includes the WMU types present at

each of the Industrial D facility sites; a full list of the 419 settings included in the representative

national data set is provided in the Appendices to Section 3.
Section 2.0 Spatial Framework

2-3

2.4 Regional Assignments

Regional assignments, including meteorological station, USGS hydrologic region, and

ground water class, are necessary so that the 3MRA modeling system can assign the correct

regional data to each site/setting. Meteorological station and USGS hydrologic region (Seaber et

al., 1987) were assigned using GIS overlays as described in Section 4.0 and Section 6.0,

respectively. Assignment of ground water class (i.e., hydrogeologic setting) is described in U.S.

EPA (1996). Appendix 2A provides these regional assignments for all 201 Industrial D facilities.

2.5 Site Layout, Spatial Data Layers, and Grid Database

Collection of site-based data for the representative national data set centered around the

use of GIS technology (ArcInfo and ArcView software) to create several key spatial data layers

for each site/WMU setting, as shown in Figure 2-1. These key areas are

# Human receptor points, defined by U.S. Census block centroids (residents) and

randomly placed farms based on block group (beef and dairy farmers),

agricultural census, and land use data (see Section 9.0). These serve as points to

calculate exposure concentrations in various media and to estimate risks to human

receptors.

# Ecological habitats, areas with assigned ecological receptors, defined by land use

and other ecologically relevant data (see Section 13.0). These areas perform a

similar function as the human receptor points for ecological receptors.

# Watersheds, delineated using digital elevation models (DEMs) of topography or

manually, based on Reach File (RF) stream networks (see Section 5.0).

Watershed subbasins provide the input data and output spatial framework

necessary to model contaminant deposition, erosion, and overland transport, as

well as resultant soil concentrations, in the LAU, Waste Pile, and Watershed

Modules.

# Waterbodies (lakes, streams, and wetlands), defined by DEMs, RF data, land use

data, and/or the National Wetlands Inventory (NWI; see Section 5.0). These

provide the input data and output spatial framework necessary to model

contaminant deposition, fate, and transport and the resulting water column and

sediment concentrations in streams and lakes.

In the GIS, each of these spatial data layers is composed of two-dimensional (2-D)

polygons, with the exception of streams, which are defined by one-dimensional (1-D) vectors

(stream reaches). Because these polygon coverages could not be exported directly to the 3MRA

modeling system, each spatial data layer was defined in terms of a base grid composed of 100 ×

100 m cells, which roughly correspond to the minimum resolution of several site-specific data

types (i.e., land use, topographic, and soil).
Section 2.0 Spatial Framework

2-4

Figure 2-1. Site-based spatial overlays for the 3MRA modeling system spatial framework.
Section 2.0 Spatial Framework

2-5

This base grid (or x,y coordinate system) serves as the basis for defining receptor points

at which the Air and Aquifer Modules produce contaminant concentrations (and deposition rates

for the Air Module) in terms of distance and direction from the WMU contaminant source. To

provide the 3MRA modeling system’s SLP with the data necessary to specify air points, spatial

data are passed to the system using this site coordinate system for the following data layers:

# Watersheds

# Waterbodies

# Farms

# Human receptor points

# Wells (human receptor points with drinking water wells)

# Ecological habitats.

These data are passed as six separate data tables within the “grid” database, along with the

Setting_ID and the necessary index (e.g., watershed number). Figure 2-2 shows the structure of

these data tables.

The site coordinate system uses x,y coordinates (in meters) relative to a 0,0 georeference

point, which is defined as the facility centroid. The 3MRA modeling system also requires

specification of the georeference point using latitude and longitude in the Universal Transverse

Mercator (UTM) coordinate system. This requires conversion of the Albers meters GIS

coordinates to UTM.

The grid tables are created using GIS by overlaying coverage of spatial data (e.g.,

watersheds) with the standard grid. If the centroid of a grid cell intersected a polygon, it receives

the identifier for that polygon (see Figure 2-3). The resulting table from this overlay is passed on

to the database processors as the table of grid cell IDs that represent that spatial feature. The

database processors then use the standard grid table of x,y points to convert the real-world UTM

coordinates to a set of x,y points centered about 0,0.

Section 2.0 Spatial Framework

A template grid was created to cover the largest AOI of the 419 site/WMU settings. This

way, only one grid needed to be created for use with all the sites. The largest WMU from the

201 selected sites (1,618,800 m2 at site 0431912) was used to define the template grid for the

example data set.

Because the template grid was created the same way for each site (centered on the site

location) the cell centroid x,y coordinates were always the same delta x and delta y from the site

centroid (0,0). As a result, only one grid definition file needed to be created. The grid definition

file consisted of the cell address, the x distance, and the y distance. A cell’s UTM coordinates

can be determined by simply adding the x and y distance from the grid definition file to the

facility centroid UTM coordinates. Cell ordering starts at 1 in the upper left corner and works its

way across horizontally and then down.

2.6 Quality Assurance/Quality Control

General QA/QC of the spatial aspects of the data collection and processing effort

included checks to ensure accuracy of facility location, proper registration (alignment) of GIS

coverages, proper placement of grid templates, and accurate transfer of grid information to the

3MRA modeling system grid database. These QC activities included

# Visual review of each facility/WMU location and manual relocation as necessary

to ensure reasonable location prior to GIS processing of spatial data (see

Appendix 2B),

# Automatic regeneration of the grid template for a site prior to GIS postprocessing

of spatial data to ensure proper correspondence with the facility centroid,

# Generation and visual review of thumbnail images of all spatial data for every site

to ensure accurate registration and collocation of all data layers, and

# Visual checks of a subset of sites in the grid database against original GIS

coverages to ensure accurate data processing and transfer.

QA/QC of specific data layers (i.e., human receptors, habitats, watersheds, and waterbodies) is

discussed in the section describing data collection for each data type.

2.7 Issues and Uncertainties

Overall, one of the most significant general uncertainties with the spatial data in the

representative national data set is the accuracy of facility location and its impacts on the sitebased data collected around each site. Appendix 2B discusses such locational uncertainties in

some detail. However, these locational uncertainties are likely to be significant only in terms of a

site-specific analysis at certain sites, and 3MRA modeling system is site-based, not site-specific.

EPA believes that the location review and adjustment efforts described in Appendix 2B resulted

in site locations representative of current and future locations of Industrial D WMUs, and, as

such, these locations are adequate and appropriate for a nationwide site-based analysis. EPA
Section 2.0 Spatial Framework

2-8

emphasizes that the site-based data collected for the 3MRA representative national data set are

not intended to be used for site-specific risk assessments.

Other issues and uncertainties associated with specific site-based data layers are found in

the sections of this report discussing each data type.

Appendix 2B. Facility Location

Because the accuracy of the facility location directly affects the accuracy of site-based

data collected for a site, an effort was conducted to collect the best locations possible. In

previous modeling applications, Industrial D facilities were located using the centroid of the zip

codes contained in the 1985 Screening Survey of Industrial Subtitle D Establishments (Westat,

1987), which does not contain facility latitude/longitude. However, the 3MRA modeling system

relies heavily on a site-based modeling approach, and accurate facility locations are critical.

To address the need for more accurate site locations, the locations of the 201 Industrial D

facilities included in the representative national data set were improved through a variety of

techniques, including the following:

# Matching facilities to EPA’s Location Reference Tables (LRT) from the

EnviroFacts database to obtain the Agency’s best location,

# Zip-code centroids using GIS software, and

# Visual placement using interactive ArcView software based on land use, WMU

features (e.g., large surface impoundments as waterbodies), and topographic maps

(when available).

The remainder of this appendix describes the source for each improved location and the rationale

for every site location adjustment. In essence, this effort helped to ensure that all Industrial D

locations used in the representative national data set are a reasonable representation of current

and future industrial nonhazardous waste management facilities.

2B.1 Data Sources

The locational improvement effort began with EPA’s LRT database, which is accessible

via EPA’s Envirofacts Web site. The following information was extracted from that Web site.

Additional information on LRT data can be found at http://www.epa.gov/enviro/html/

lrt/lrt_over.html.

The LRT database serves as a repository for information collected as a result of EPA’s

1991 Locational Data Policy (LDP). The primary objective of the LDP is to identify, collect,

verify, store, and maintain an accurate, consistently documented set of locational data for entities

of environmental concern. A secondary objective is to support the infrastructure needed to

manage these data in a manner that yields integration across national, regional, tribal, and state

systems. The intent is to support EPA’s movement toward data integration based on location,

thereby promoting the use of EPA’s data resources for a wide array of cross-media analysis.
Appendix 2B Facility Location

2-22

The LRT component of Envirofacts contains data extracted from the Section Seven

Tracking System (SSTS), the National Compliance Database (NCDB), the Federal Facility

Information System (FFIS), the PCB-Handler Activity Data System (PADS), and five program

systems in Envirofacts: 

# Aerometric Information Retrieval System (AIRS)/AIRS Facility Subsystem

(AIRS/AFS),

# Comprehensive Environmental Response, Compensation, and Liability Act

(CERCLA) Information System (CERCLIS),

# Permit Compliance System (PCS),

# Resource Conservation Recovery Act Information System (RCRIS), and

# Toxics Release Inventory System (TRIS). 

These data were geocoded and loaded into the LRT. Envirofacts records in the LRT are updated

monthly as part of the Envirofacts refresh. 

LRT includes Method Accuracy Description (MAD) codes that provide positional

accuracy for each location and are assigned by method. These include derived, provided, and

default values. Table 2B-1 shows the MAD codes and their level of accuracy.

2B.2 Review of Locational Accuracy

Additional information on the accuracy of the LRT locations was obtained during the

3MRA modeling system data collection pilot. Facility front gate locations were obtained using

global positioning system (GPS) technology and compared to zip code centroid and the best LRT
Appendix 2B Facility Location

2-23

locations available for five Industrial D facilities. Significant conclusions drawn from these

comparisons are the following:

# At Site A (urban setting), an I1 “facility centroid” location was available from

LRT. In this case, the LRT location provided a more accurate location for the

onsite WMUs (surface impoundments) than did the front gate GPS location.

# At Site B (rural setting), only a zip code centroid location was available from

LRT. In this case, the inaccuracy of the zip code centroid would have resulted in a

significant difference in population estimates within the area of interest. The zipcode-based area overlapped a nearby town, resulting in a population estimate for

the NW quadrant more than an order of magnitude higher than the estimate that

would result from the GPS front gate location.

# Site C (rural industrial setting) had three facilities nearby. LRT facility centroid

locations for each of these were somewhat offset from the GPS front gate

locations; in one case, the LRT facility centroid was in a swamp across a large

river from the facility. In this case, the GPS locations provided better estimates of

WMU locations than the best available LRT locations.

In summary, even the better I1 locations can be somewhat inaccurate, and zip code

centroid locations can significantly over- or underestimate population around a site. Based on

this experience, a site relocation effort was developed to find, for each facility modeled,

reasonable locations that represent likely locations for industrial Subtitle D waste management

units (WMUs).

2B.3 Automated LRT Matching through Envirofacts (2,850 Sites)

Figure 2B-1 illustrates the automated methodology used to obtain LRT locations for the

entire database of 2,850 Industrial D facilities. This involved using largely automated methods

to match facilities in the Industrial D Screening Survey to EPA facility IDs and to obtain the best

LRT locations for each facility. The methodology included

# Matching Industrial D Dun and Bradstreet (DUNS) numbers to EPAIDs in

Envirofacts databases with DUNS numbers (TRIS, FINDS, and AIRS/AFS),

# Developing DUNS-based “pseudo-EPAIDs” for Industrial D facilities and

matching to PCS and other Envirofacts data tables, and

# Automated and manual matching of Industrial D facility zip code and address to

Envirofacts LRT data.

2B.4 Address Matching and Manual Techniques: 201 Sites

Once the 201 Industrial D sites were selected for the representative national data set,

additional effort was made to get improved locations for those 201 sites. These efforts included

# Manual matching through the Envirofacts query form was done for sites in the

201 that were not already matched to Envirofacts locations. This resulted in an

additional 45 sites matched to EPA IDs. 

# Using a table of all available EPA IDs, for 181 of the 201 sites, to query the

Envirofacts database to ensure that the best location was obtained for the sites

from the LRT. This resulted in 12 new locations being added to the database as

well as a few more accurate locations for sites already with LRT locations. 

# Filling in remaining sites (without LRT locations) with zip code centroid latitude

and longitudes using the ESRI ArcView Data Disk (data from a Geographic Data

Technology, Inc., 1995 database). 

Table 2B-3 shows the method and accuracies of the 201 site locations, including 66 locations

based on 5-digit zip codes.

2B.5 Manual Location Review and Adjustment

During the initial watershed delineations of the sites, it became apparent that some

locations would cause problems in the data collection process if they were not moved. Some

locations put WMUs in rivers or other waterbodies. Other sites ended up in areas of

inappropriate land use (e.g., large surface impoundments in residential land use areas). 

To ensure that all sites were in reasonable locations with respect to land use, GIS

coverages imported for data collection (including GIRAS land use, RF3 and NWI waterbodies,

and zip code coverages), DeLorme topographic road atlases, and digital USGS topographic

quadrangles (where available) were used to review all site locations and adjust inappropriate

locations to better locations. In some cases, usually with large surface impoundments, the actual

WMUs could be found using the various waterbody coverages provided by GIS or on the

topographic maps. Attachment 2B-1 (at the end of this appendix) shows the sites moved from

the initial locations described above to the final locations used for data gathering, including an

explanation of why each site was moved.

2B.6 Quality Assurance/Quality Control

QA/QC activities for this effort included automated matching of zip codes and addresses

between the Industrial D and LRT data to identify spurious facility locations and duplicate

locations, which were then screened manually to eliminate duplicates and mismatched data.

Manual checks of the matched sites (using facility name, address, and zip code comparisons)

were conducted to verify the automated matching process. Whenever zip codes or addresses did

not agree, manual verification was conducted. A manual review of all site locations using the

GIS coverages was also done to identify sites that needed to be moved to more appropriate

locations.

2B.7 Issues and Uncertainties

Uncertainties associated with the Industrial D facility locations include the following:

# For some sites, problems were encountered even with the most accurate locations

from the Envirofacts LRT data. As shown in Attachment 2B-1, even a few

facilities with accuracies of 150 meters or less had to be moved due to problems

with the original location. One site with an LRT locational accuracy of 2 to 3 m

(an I1 location) needed to be moved 10,047 m to remove the facility from a large

bay that entirely covered the 2 km radius.

# While every attempt was made to move poorly located sites to the best locations

possible, there was still no way to know exactly where the actual facility was

located. Some facilities with only zip code centroid locations were moved to

suitable land use (based on professional judgment) within a rather large zip code

district.

However, these uncertainties should be considered in the context of the intended

nationwide use of the 3MRA modeling system; although site-based data are the basis for the

representative national data set, and the site-based data are determined by where each site is

located, the representative national data set is not intended to support site-specific analysis.

Within this context, the 201 facilities and their locations as presented herein were derived to

adequately represent likely locations of Industrial D facilities across the nation.
