RC6: Conducting Effective Stakeholder Engagement

Helen A Grogan, PhD

Cascade Scientific

objective
Objective

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.

slide4
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
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

 (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
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.

slide10
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?

study objective
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.

requirements
Requirements
  • 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
We did not take account of
  • Cost of cleanup
  • Risks to the public associated with cleanup
  • Institutional controls
slide17
RSAL = radionuclide soil action level

Dconstraint = (0.15 mSv y-1)

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

slide18
We considered lifestyles, occupations, diets, etc., for people who may inhabit the land in the future.
slide21
We concluded a rancher living on the land with his family is the scenario that would lead to the highest dose.
slide22
A prairie fire could significantly increase the dose because of greater resuspension following the fire.

question two
Question Two

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

data gathered in consultation with the tribes
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
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 ?

background
Background

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.

remember these points about stakeholder participation
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
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?
