RC6: Conducting Effective Stakeholder Engagement

Helen A Grogan, PhD

Cascade Scientific


To recognize the importance of credibility and trust for effective stakeholder engagement.

To show different ways that this can be achieved using case studies that highlight different aspects of the process.

Our Ultimate Goal with the Public is



Building credibility and trust in risk assessment is as important as the science itself.

Why Credibility and Trust are Essential

  • If we carry out the best possible environmental risk assessment but in the end find that the results are not believed, then we have failed in our objective.

Building Credibility and Trust

Must be based on data and science

Must be transparent

Must be effectively communicated

Must be earned

Must go beyond what is expected

ICRP Publication 82

 (58) In the wider decision making process, the role of all interested parties, usually termed stakeholders, should be recognized. This recognition is particularly important in cases of remediation and rehabilitation of land with residues from past activities and events. The extent of stakeholder involvement will vary from one situation to another…. The weight given to these interests could be an important factor in the acceptability of the ultimate decision.

Who Are Stakeholders and What Is Their Authority?

Stakeholders are individuals who have a personal, financial, health, or legal interest in policy or recommendations that affect their well-being or that of their environment.

Operators and regulators are decision makers and the stakeholders help in the process by providing information and guidance related to decisions being made.

There is stakeholder engagement...

…and there is stakeholder engagement

Question One

Do you believe stakeholders can play a role in making policy recommendations and can help us make better decisions about protecting the environment?

The Rocky Flats Facility Is Located Near Denver Colorado

> 370,000 (0.24 ha.)

Study Objective

These activity levels are called Radionuclide Soil Action Levels or RSALs

To estimate the levels of plutonium and other actinides in soil released from Rocky Flats such that subsequent human exposure during future use of the site does not result in levels of radiation dose that exceed specified limits.

The Radionuclide Soil Action Level Oversight Panel


  • 0.15 mSv per year dose constraint

  • Unrestricted use of the land

  • 1000 year time frame

  • Use of available site specific data

  • Account for uncertainties

We did not take account of

  • Cost of cleanup

  • Risks to the public associated with cleanup

  • Institutional controls

RSAL =radionuclide soil action level

Dconstraint = (0.15 mSv y-1)

DSR =dose-to-source ratio (mSv per Bq kg–1).

We considered lifestyles, occupations, diets, etc., for people who may inhabit the land in the future.

Rocky Flats is surrounded by areas of wild grass like this area located north of the site.

Resuspension of plutonium contaminated soils was a dominant exposure pathway

We concluded a rancher living on the land with his family is the scenario that would lead to the highest dose.

A prairie fire could significantly increase the dose because of greater resuspension following the fire.

Question Two

Do you believe stakeholders can help us conduct better science to be used for making recommendations about protection of the environment?

The Hanford Site Is Located in Southeastern Washington State

Native American Treaty Protected Rights and Resources

Data Gathered in Consultation with the Tribes

Nine tribes each collected primary dietary & residential mobility data (1944-46 & 1961-63)

Tribes also summarized distinctive patterns of food preparation, occupational niches, seasonal variation, ceremonial activities that may have led to exposures distinct from the general, non-Indian population

Involvement of Native American stakeholders in the study increased the state of the art of knowledge about pathways

Their involvement also significantly improved our credibility both with Native American people and with other stakeholders

Question Three

Do you believe by involving stakeholders in the decisions and recommendations we make today, these will be more enduring and better accepted in the future ?

Los Alamos National Laboratory



Audit conducted as part of a settlement agreement and consent decree that resolved a lawsuit filed against the U.S. Department of Energy.

As part of the consent decree, Risk Assessment Corporation, was asked to lead the audit.

Question posed was, “Did Los Alamos National Laboratory meet requirements for compliance with the Clean Air Act?

The stakeholder group appointed representatives to monitor and verify the audit’s integrity.

The Audit Process Changed in the Procedures and Documentation of Future Audits

Remember These Points About Stakeholder Participation

Recognize the difficulty of this commitment

Understand that short term costs are greater

Clearly define the role and authority of stakeholders

Develop a plan for receiving and responding to stakeholder input

Have a well defined schedule and product for the end

Recognize that once the commitment is made to involve stakeholders, you cannot retract the commitment

Question Four

Do you believe it is possible to conduct environmental risk assessment that is based on sound science while being transparent and flexible and involves stakeholders in the decision-making process?

Cerro Grande Fire (May 2000)


Key Findings from Cerro Grande Fire


Data not consistent or accessible

Lack of transparency in decision process

Communication of decisions not effective or timely


Risk evaluation difficult and lengthy process

Lack of confidence in results and distrust of decision makers


Foundation for RACER®

Clear objectives

Integrated processes

Open and consistent communication

Tools to relate data and information to decisions






What is RACER®?

An innovative approach to support decision making and communication related to risks from chemicals and radionuclides in the environment


Principles of RACER®

  • Make environmental data consistent and accessible

  • Provide a framework that links environmental data and human health

  • Emphasize relative comparisons for decision making and communication

  • Engage Stakeholders




Optimize sample locations

Spatial and

temporal trends

Turning Data Into Information and Knowledge

RACER® Process

Incorporates a series of tools into the risk assessment process for:

Data analysis

Risk analysis



Data Analysis Tool

Electronic transfer of data to the database

Linked to a relational database of relevant environmental data

Provides options for selecting and analyzing data
