Integration of Triad into Site Management Planning
Thomas Palaia, CH2M Hill
This presentation prescribes a data management and decision support system as a critical success factor to sustain the long-term viability of Triad via incorporation of Triad data into the overall site management decision making process. This can be accomplished by effective integration of multiple data-use-specific software components which enable efficient data compilation and decision making. As it relates to Triad, site management planning typically involves the following core tasks:
- Analysis of the site conceptual model (SCM) certainty
- Identification of metrics for cessation of Triad data collection
- Assessment of data adequacy to support evaluation of multiple potential site management approaches
- Identification of the optimum site management strategy
Within the context of this presentation, the term "site management" is intended to be generic because it signifies that these tasks are applicable to many diverse Triad projects. Site management is inclusive of many remediation-related actions ranging from selection of a proper excavation volume, to selection of a technology for partial mass removal at a site containing dense non-aqueous phase liquid.
To enable efficient selection of a site management strategy within the short duration of a Triad project, a core set of decision support tools are needed to assist project team members. The toolset described in this presentation includes:
- A geospatial database to compile and visualize collaborative data sets,
- A three-dimensional visualization and animation system to illustrate contaminant fate and transport, and
- A multi-criteria decision support tool to assist with, among many tasks, analysis of SCM certainty and selection of a site management strategy.
The purpose of this presentation is to demonstrate that integration of this toolset can fulfill the data management needs of a Triad project as well as serve a long-term use as a full life-cycle environmental remediation database and decision support system.
Building a Consensus Vision Using Conceptual Site Models
Robert Howe, Tetra Tech EMI
To expedite a project reaching its goals as efficiently as possible, it is important to build a consensus vision among stakeholders who commonly have differing expectations for a successful project. A team's ability to build an adequate CSM to arrive at a consensus vision may depend on the following key factors: 1) clarity of CSM presentation; 2) amount of data available for the site; 3) clarity of the intended reuse; 4) stakeholder expectations and past experiences; and 5) economic and time constraints.
Complexities at a site need to be simplified into easy to understand CSM elements that enhance a Triad advocateÕs ability to build consensus vision among project stakeholders. When complex issues of the CSM are presented in a simple and sensible fashion, they become integrated into the stakeholder's consensus vision. With an increased understanding of site issues, stakeholders take ownership of a project and can more clearly express their project concerns. If data collection is needed, a preferred sequence of efforts should be agreed on to promote confidence in specific elements of the CSM. Clarity of reuse can be an important controlling factor for a project. Use of the CSM to demonstrate potential cost impacts can motivate stakeholders to move toward the available reuse options, before proceeding with the preparation of project work plans.
During this seminar, CSM work products and strategies for building consensus visions at sites will be discussed. Lessons learned and examples of what has worked and not worked at sites in various stages of the planning and implementation process will be presented. Methods for bringing consensus vision with stakeholders during project design will be discussed in the context of real-world examples from the U.S. EPA Brownfields, Superfund, and RCRA technical support programs.
