Risk-Screening Environmental Indicators (RSEI) Model

RSEI Data Dictionary: Elements Data

                                                               Tables in the RSEI Data Dictionary
Facility NAICS Submission Disaggregated Microdata Census Crosswalks
EPA Program IDs (Reporters) Chemical Release Aggregated Microdata Population Data
Offsite MCL Elements Block Group Microdata Shapefiles
EPA Program IDs (Off-sites) Media Category Water Microdata  

The Elements table contains the calculated results for each release. There can be multiple elements records for each release. Note that all values in the elements table are rounded to six significant figures.

The Submission, Elements and Release tables are too large for spreadsheet format.

Elements Data

Variable Description
ElementNumber Unique internal identifier.

ReleaseNumber

Unique internal identifier (links to Release table).
PoundsPT
(TRI Pounds)
Total pounds after any treatment by POTWs or other offsite facilities.
ScoreCategory Codes corresponding to the medium into which the chemical is released. Examples of the information include: direct air releases from the stack using a “rural” air dispersion model, fugitive air releases, releases to an onsite landfill. [See Category table for descriptions]
Score
(RSEI Score)
Total Indicator Element score- modeled surrogate dose multiplied by toxicity weight and by population, using the higher cancer/noncancer toxicity weight for each air/water pathway.
Population Total population exposed.
ScoreA Score for children 0 through 9 years of age (inclusive).
PopA Number of exposed children 0 through 9 years of age (inclusive).
ScoreB Score for children 10 through 17 years of age (inclusive).
PopB Number of exposed children 10 through 17 years of age (inclusive).
ScoreC Score for adults 18 through 44 years of age (inclusive).
PopC Number of exposed adults 18 through 44 years of age (inclusive).
ScoreD Score for adults 45 through 64 years of age (inclusive).
PopD Number of exposed adults 45 through 64 years of age (inclusive).
ScoreE Score for adults 65 years old and greater.
PopE Number of exposed adults 65 years old and greater.
NCScore (NonCancer Score) Indicator Element score, limited to chemicals with non-cancer endpoints.
CScore (Cancer Score) Indicator Element score, limited to chemicals with cancer endpoints.
Hazard
(RSEI Hazard)
Toxicity weight times TRI pounds, using the higher cancer/noncancer toxicity weight for each air/water pathway.
HazardC
(Cancer Hazard)
Toxicity weight times TRI pounds, limited to chemicals with cancer endpoints.
HazardNC
(Non-Cancer Hazard)
Toxicity weight times TRI pounds, limited to chemicals with non-cancer endpoints.
