exposure or risk assessment; variability and uncertainty assessment;

deterministic or probabilistic assessment; etc.*

*List any additional features that describe the scope of the project.*

**Is the risk assessment done for an individual source (e.g., a

**Which pollutants are assessed? Are they assessed individually or on a
cumulative basis?**

**Does the project consider ambient/background concentrations in
determining exposure?**

**What conservative assumptions are made? What "best estimate"
assumptions are made?**

*Conservative assumptions might include permitted emission levels and
lifetime exposures. Best estimate assumptions might include reported
emission levels and shorted duration exposures.*

**What cancer and non-cancer toxicity dose response values are used? Do
they differ from the EPA IRIS values? What is the data source for the
values?**

*Potential toxicological values used for the health effects assessment
can include: Cancer slope factors, cancer unit risk factors, noncancer
reference concentrations (RfCs), noncancer reference doses (RfDs),
risk-based concentrations (RBCs), risk-based doses (RBDs), other (please
describe).*

**What assumptions are made when a match from chemical emitted to
toxicity value is not exact?**

*For example, if emissions are not speciated or if toxicity value is not
known?*

**What is the basis for emission estimates used in the project -- actual
or allowable?**

*Provide additional information on the development of the data sources,
if needed.*

**What exposure pathways are assessed?**

*Inhalation, ingestion, mutipathway, etc.*

**What assumptions are made in considering exposure pathways?**

*For example, concentrations in food items?*

**For inhalation exposure assessment, is exposure modeling conducted
(i.e., consideration of changes in pollutant inhalation concentrations
in different locations frequented at different times by population(s) of
interest)? Or is there an assumption of continuous exposure to outdoor
air over a certain time period?**

**Will the project be subject to a peer review process? If so, please
describe briefly.**

**[IV. FINDINGS]{.underline}**

**If no findings are available go to section V, Outcomes and Reduction
Activities.**

**What are the media concentration or exposure results?**

*For example, what were the air concentrations used to estimate risks?
What were the significant (perhaps maximum) air concentrations for HAPS
without toxicological dose response values?*

**What are the individual cancer risk estimate results:**

*An estimate of an individual's excess cancer risk from a lifetime of
exposure are often developed using unit risk estimates (URE) that are
based on a lifetime exposure of 70 years. For example, the lifetime
individual risk from continuous breathing current levels of pollutants
in California is estimated to be 7.6 x 10^-4^ or 760 in one million.
These risks may be expressed as a single number or as a range to
indicate variation in exposure factors, chemical compounds, exposure
location, emission rates, etc.*

> **What is the cancer risk estimate for the maximum exposed individual
> (MEI)? What HAPs drive the risk?**
>
> *MEI risks are estimated from the highest air concentration outside
> the facility fenceline [whether or not individuals reside
> there]{.underline}.*
>
> **What is the maximum individual risk (MIR)?** **What HAPs drive the
> risk?**
>
> *MIR's are estimated from the highest air concentration outside the
> facility fenceline [where individuals reside]{.underline}.*
>
> **What are the maximum worker cancer risk estimates (if developed)?**
> **What HAPs drive the risk?**

**What are the individual non-cancer risk estimates: MEI, MIR, worker?
What HAPs drive the risk?**

*Health reference levels are an example of one index that government
agencies use in characterizing noncancer health risks. Generally used in
EPA\'s noncancer risk assessments for inhalation exposures, the
reference concentration (RfC) is an estimate (with uncertainty spanning
perhaps an order of magnitude) of a continuous inhalation exposure to
the human population (including sensitive subgroups) that is likely to
be without an appreciable risk of deleterious effects during a
lifetime.*

*Results are often expressed in terms of a hazard quotient (HQ) (ratio
of a single substance exposure level over a specified time period to a
reference concentration for that substance derived for a comparable
exposure period) or hazard index (HI) (sum of more than one hazard
quotient for multiple substances and/or multiple exposure pathway).*

**What are the target-organ specific hazard indices (TOSHI)? If they
weren't developed, why?**

**What are the population risk results?**

*For both cancer and noncancer risks, the population risk is usually
expressed as the number of people estimated to be at various levels of
risk. Population cancer risk can also be expressed as the predicted
increased incidence of cancer (that is, the number of new cases each
year) for all people exposed to the pollutant. For example, the
estimated population cancer risk may be the number of new cancer cases
per year predicted among residents within 30 miles of a certain large
source.*

**What other results were found as part of this project?**

*An example is blood lead estimates for children's exposure to lead.*

**What pollutants were identified as being of concern? On what basis?**

*What pollutants were found to contribute most to risk of adverse health
effects or found in highest concentrations?*

**What sources of pollution were identified as being of concern?**

For example sources may be in the following categories: non-located area
sources, located stationary sources, ambient area, road and non-road
mobile sources, and diesel/gasoline sources. *Provide specific sources
if known.*

**[V. OUTCOMES AND REDUCTION ACTIVITIES]{.underline}**

**As a result of this project, will further data be collected,
monitoring be conducted, or additional problem identification studies
undertaken? Will refinements be made to modeling or exposure and/or
toxicity assumptions?**

risk and/or emissions or otherwise mitigate the impacts of the problems

*Examples of recommendations include: encouraging control of HAP from
mobile sources, educating a community about the impacts of indoor air
pollution, encouraging appropriate action to reduce diesel truck
