The Use of the Risk Screening Environmental Indicators

(RSEI) Program to Evaluate 15 Counties of Northwest

Florida

TRI & RSEI Evaluations

What Is the Toxics Release Inventory (TRI)?

The TOXICS RELEASE INVENTORYBegun in 1988 with ~450 chemicals, the Toxics Release Inventory now contains information on releases of nearly 650 chemicals and chemical categories from industries including manufacturing, metal and coal mining, electric utilities, and commercial hazardous waste treatment, among others.

What Is the Risk-Screening Environmental Indicators

Model?

RSEI is a screening-level model for assessing potentialchronic human health impacts of industrial releases of toxic chemicals:

RSEI provides the following types of screening analyses:

RSEI uses TRI pounds of release data and adds toxicity, fate and transport, and an estimate of exposed population to allow new perspectives on hazard and risk.

Pounds Hazard Risk-related

WHO MUST REPORT TO TRI

A plant, factory, or other facility is subject to the provisions of Section 313 if it meets all three of the following criteria:

It is included in a covered Standard Industrial Classification (SIC) code

It has 10 or more full-time employees (or the equivalent of 20,000 hours per year); and

It manufactures, imports, processes, or otherwise uses any of the EPCRA section 313 chemicals in amounts greater than the “threshold” quantities. At present, over 650 chemicals and chemical categories are covered.

RSEI and Risk Assessment

RSEI incorporates components of risk assessment:

Amount of chemical released

Toxicity of the chemical

Fate and transport of the chemical

Route and extent of human exposure

Number of people affected

RSEI is NOT a formal risk assessment, but is useful for performance measurement, prioritization, and trend analysis because it systematically incorporates toxicity and exposure considerations in a screening-level analysis.

How RSEI Works -- Calculations

Pounds-based results = TRI Pounds released

Hazard-based results = Pounds * Toxicity Weight

Risk-related results = Surrogate Dose * Toxicity Weight * Population

   

RSEI Model Details

Inhalation (Air) surrogate dose - divides U.S. and territories into 1-km x 1-km grid

cells calculates air concentrations for each cell in

101 x 101 km grid around facilities uses population-specific exposure factors

Ingestion (Water) surrogate dose - calculates water concentrations in receiving

streams up to 200 km downstream of outflow finds downstream drinking water intakes calculates fish ingestion exposure for population

within 80 km of receiving stream uses population-specific exposure factors

What Kinds of Questions Can RSEI Answer?

What are the trends in hazard and risk associated with toxic chemical releases and other waste management activities at industrial facilities?

When comparing industries, how can I rank which industry sectors are associated with relatively more risk?

What is the relative contribution of specific chemicals to overall risk in a community (state, county, city), and how do I prioritize these for follow-up activities?

For any given scenario, what release pathway for a particular chemical poses the greatest risk-related concerns?

Also questions concerning: Tribal lands, EJ issues, important age groups (e.g., children & elderly), etc.

How Is RSEI Data Processed?

1. Select Search Parameters (NWFL – Selected 15 Counties)

2. Setup a table Table includes Facility Name,

Chemical, Media, SIC Code, and County

3. Export to Excel 4. Setup Pivot Tables & Charts

Using RSEI as a Targeting Guide for Pollution

Prevention Rank counties, industries, chemicals,

and facilities by Pounds Released and Relative Risk using RSEI.

Florida DEP used the TRI and RSEI charts of Northwest Florida to select several facilities to approach about Pollution Prevention (P2) activities.
