Scoping, part 2

Steve White, MURPOregon Public Health Institute

Session Agenda

1.Questions from yesterday’s scoping work

2.Quick review of Scoping outcomes

3.“How” Case Study Example

•Lake Oswego to Portland HIA

4. “How” Exercises

•Workbook worksheets

Scoping Outcomes

4. A brief summary and logic model of the pathways through

which the population’s health and health determinants

could be affected and the health effects to be addressed.

5. A description of the health determinants and outcomes that

will be assessed in the HIA, as well as the rationale for why

they were selected over others

Scoping Outcomes

7. A description of the research questions, data sources,

and methods to be used.

8. Identification of apparent data gaps and of data

collection that could be undertaken to address the gaps

or a rationale for not undertaking data collection.

9. A timeline of assessment activities, including who is

responsible for completing each activity

Scoping Exercises

1. Pathway Diagrams

2. Research questions, data needs, and possible

methodologies

• Metro (MPO)-led DEIS focusing on evaluating 3 transit alternatives for the Hwy 43 corridor

• No-build• Enhanced Bus• Streetcar

• Key Decision: Selection of a “Locally-Preferred Alternative”

Instructions Scoping worksheet 5: Research questions, data needs, and assessment methodology, by health determinant*

Project: LOPT Transit Study Geographic Scope:

Local, Hwy 43 corridor

Health Determinant/Outcome:

Concentration of outdoor air pollutants

Temporal Scope:

Short term, construction phase

Research Questions: Existing Conditions

(of health determinants and health outcomes)

Research Questions: Potential Impacts (on health determinants

and health outcomes)Possible

Indicators Data Sources Methodology

Priority (High,

Medium, Low)

What are current levels of diesel engine -related air pollutants in the Hwy 43 corridor?

How will concentration levels of these pollutants change as a result of the different scenarios?

Modeled existing concentration levels of key air toxics; Gallons of diesel used in construction

DEQ’s PATS database, DEIS projections for diesel use in construction, EPA/OSHA reports on construction AQ

Project emissions from construction activity based on different fleet scenarios

Med/ high

How do rates of asthma or other respiratory illnesses compare with regional averages?

Would these conditions likely be exacerbated by construction activity?

Hospitalization rates

??? Look for possible local studies.

Lit. Review Med/ low
