Introduction: HHRA
˃ Fate and Transport Modeling provides a means to estimate the movement and alteration of “chemicals” as they move through environmental media including air, soil, surface water, and sediment; and interaction with biological systems including flora, fauna, and human receptors
˃ Exposure Modeling includes identification of the exposure pathways by which “chemicals” may reach individuals� Estimating how much of a chemical an individual is likely
to be exposed to
� Estimating the potential health effects (e.g., cancer, non-cancer, short-term)
7© 2016 Trinity Consultants | Riverstone Environmental | All rights reserved
BREEZE Risk Analyst
˃ Human health and Ecological risk assessment modelling suite developed to perform multi-media fate and transport and exposure modeling
˃ For estimating potential adverse impacts to human health and ecological receptors
˃ Food-web based ecological risk assessment modeling
˃ Highly flexible GIS based modelling, data analysis and reporting system
BREEZE Risk Analyst

HHRAP Module (USEPA, 2005)
HHRAP Module
˃ USEPA Guidance document for performing site-specific, multi-media, and multi-pathway human health risk assessments (HHRA)
˃ Originally developed to support RCRA Hazardous Waste Combustion Permitting
˃ Guidance includes:
� Risk Assessment Methodologies♦ Chemical selection process
♦ Air Dispersion Modeling
♦ Exposure scenario and pathway selection
� Fate, Transport, and Exposure Equations
� Chemical Database
� Recommended Parameter Defaults
9© 2016 Trinity Consultants | Riverstone Environmental | All rights reserved
HHRAP Module
˃ Use of the HHRAP has significantly expanded outside its
original role in RCRA Permitting. Example include:
� Air Toxics Risk Assessment (ATRA) Reference Library
� Cumulative/Community Risk Assessments
� Toxic Tort/Odor Nuisance Litigation
� Environmental Impact Statements (NEPA – EIS)
� Environmental Justice
� Residual Risk
� Ecological Risk
� Air Quality Studies
HHRAP Module
˃ BREEZE Risk Analyst - Fully implements the USEPA HHRAP
˃ Chemical Database includes over 400 HHRAP chemicals
˃ Chemical types include volatiles, semi-volatiles, and metals
including:� Polychlorinated dibenzo(p)dioxins (PCDDs) and polychlorinated
dibenzofurans (PCDFs)
� Polynuclear aromatic hydrocarbons (PAHs)
� Polychlorinated biphenyls (PCBs)
� Nitroaromatics
� Phthalates
� Other organics (e.g., Benzene, Cumene, 1,3-Butadiene)
� Metals (e.g., Mercury, Lead, Arsenic, Chromium)

Development Objectives
˃ The objective was to develop a highly flexible GIS-
based modeling, data delivery, analysis, and reporting
system that integrates multi-media and multi-pathway
fate and transport, exposure, and health effects
modeling including cancer risks, non-cancer hazards,
and short-term acute effects
˃ The system is designed to provide a platform upon which to support the evolving requirements and environmental challenges of many of today’s most important regulatory and non-regulatory applications.
Development Objectives
˃ Support multiple air dispersion models (e.g., ISC,
AERMOD, CALPUFF, SCIPUFF)
˃ Support multiple air modeling result output formats
˃ Highly transparent - eliminate “black box” modeling
˃ Provide a scalable modeling system – “Risk Modules”
˃ Support multiple application formats
˃ Support multiple user communities (e.g., risk assessors,
regulators, permit writers, risk managers, consultants,
industry, community and public interest groups)

˃ Intuitive process flow designed to follow steps in the risk assessment process
˃ Efficient data storage and managed project files ensure projects are easily transportable between users
˃ Advanced error logging and numeric validation reporting options
˃ Highly flexible air modeling import wizard provides users with the tools necessary to import modeling results from a wide variety of air dispersion models (e.g., ISCST3, AERMOD, CALPUFF, and SCIPUFF) and in multiple data formats
˃ Fully editable and comment-enabled chemical database
˃ Unprecedented Base Map format and data import/export options
˃ Advanced attribute and geospatial selection tools
Features
˃ Detailed parameter and equation descriptions and reference information provided using selection sensitive property grid controls.
˃ Advanced text and drawing annotation tools enable the generation of graphically rich custom maps and report figures.
˃ Convenient HHRAP equation parameter matrix included to quickly identify equations and the location of individual input parameters.
˃ Mercury Wizard guides users of all experience levels through the process of mercury speciation and phase allocation.
˃ Powerful water body and watershed identification and delineation tools.
˃ Fully Transparent Results – the user has full access to equations, input parameters, and intermediate calculations
14© 2016 Trinity Consultants | Riverstone Environmental | All rights reserved
Features
˃ Robust Analysis Options - Analyze individual emission sources, source groups, chemicals, chemical groups, exposure scenarios, and exposure scenario locations or simultaneously analyze thousands of source, chemicals, scenario, and location-combinations.
˃ Advanced cartographic tools including fully customizable mapping symbology, legends, scale bars, labeling, orientation arrows, and geographic coordinates.
˃ Powerful map export options including standard graphics formats, pdf maps, and Google Earth
˃ Advanced statistical data analysis and reporting tools.
˃ Sort, filter, query, threshold, and exceedance options.
˃ Customizable result reporting and viewing options.
Features
˃ Results can be managed in ArcViewTM or exported as MS
Excel, MS Access, ESRI Shapefile, XML, Txt, or HTML
format for use in other applications or further analysis
and reporting using advanced ArcViewTM features.
˃ Generate Population-level Risk Estimates using either
cancer burden or user defined cancer risk and non-
cancer hazard levels.
