Risk-Screening Environmental Indicators (RSEI) Model

RSEI Data Dictionary: Off-site Data

                                                               Tables in the RSEI Data Dictionary

The Off-site table contains the condensed list of quasi-unique off-site facilities to which TRI reporters transfer waste. Only incinerators and POTWs are modeled by RSEI, so verification of addresses and locations are focused on those off-site facilities.

Off-Site Data

Variable Description
OffsiteID Unique internal identifier for each off-site facility (text format).
FacilityNumber Unique internal identifier for each off-site facility (integer format). [Note this is different from the FacilityNumber field in the Facility table]
TRIFID Unique identifier from TRI, if offsite facility also reports to TRI (note, this is used for incinerators, and should not be relied on for crosswalking offsite facilities and reporting facilities).
DropIncinerator True if off-site has been identified as a TRI reporter or a RCRA hazardous waste incinerator.
POTW_Incin Identifies off-site facilities for which releases are modeled: 1= POTW; 2=Incinerator; 3=POTW and Incinerator.
Name Best submitted name for off-site facility.
Street Best submitted street address for off-site facility.
City Best submitted city for off-site facility.
State Best submitted state for off-site facility.
ZIPCode Best submitted ZIP code for offsite facility.
ZIP9 This variable is not yet implemented.
Latitude Geocoded latitude in decimal degrees for off-site facility.
Longitude Geocoded longitude in decimal degrees for off-site facility.
GridCode Number that identifies the model grid within which the cell is located.
Country Null if off-site facility is located in the U.S.; otherwise country in which off-site facility is located.
X Assigned grid value based on latitude.
Y Assigned grid value based on longitude.
Radial Distance Distance from approximate center point of grid.
StackHeight Stack height used for modeling.
StackVelocity Stack velocity used for modeling.
StackDiameter Stack diameter used for modeling.
StackParameterSource Null if default stack parameters were used; otherwise source for stack parameters.
FRSID EPA's Facility Registry System (FRS) identifier.
FRSYear Year that the offsite facility was matched to the FRSID.
HEM3ID The ID assigned to the nearest National Weather Service (NWS) observation station.
DistanceToHEM3 The distance between a facility and the nearest observation station.
WBANID The ID assigned to the Weather Bureau/Army/Navy WeatherStation nearest to the facility. 
DistanceToWBAN The distance between a facility and the nearest WBAN weather station (m). 
WaterReleases 1 if off-site facility receives transfers to POTW.
OutfallLongitude Latitude associated with end of the pipe used for off-site facility’s discharge to water.
OutfallLatitude Longitude associated with end of the pipe used for off-site facility’s discharge to water.
NearReach 14-digit NHDPlus reach identifier associated with the reach that is nearest to off-site facility.
NearComID ComID from NHDPlus dataset that uniquely identifies reach segment nearest facility.
DistanceToReach The distance between an off-site facility discharging to water and the reach of the receiving water body (m).
AssignedReach 14-digit NHDPlus reach identifier associated with reach assigned by EPA or determined through QA.
AssignedComID ComID from NHDPlus dataset that uniquely identifies reach segment for assigned reach.
ReachSource Data source linking stream reach to facility.
ReachNotes Notes pertaining to stream reach assignment.
LatLongSource Source used to determine off-site facility coordinates. NA identifies records with insufficient information to determine location.
LatLongYear Year lat/long was last updated.
LockLL True if location was confirmed as correct using satellite data.
CentroidAdjustment True if facility’s FRS coordinates were modified from front door or street to approximate center of facility.
NotesOnCoordinates Notes on how off-site facility coordinates were derived.
AdditionalSourcesforLocation Web site, if any, used to determine location.
LocationConfidence Code describing confidence in location assigned to off-site:
1 = Confirmed in satellite view on map.
2 = Substantial information supporting location, including physical features such as settling ponds (2a), or a match to a business entry in google maps (2b).
3 = Geocoded address looks plausible given type of facility.
4 = No information to support geocoded address.
Foreign 1 if off-site is located outside the U.S.
