Remedial Priority System

Request for Participation in Remedial Priority System Team
June 1, 2010

A public meeting was held on May 24, 2010 at which time the Department explained the system and demonstrated the technologies and rational behind its development. The Department is now forming stakeholder teams to evaluate the appropriateness of this first model and solicit ideas for its further development. The teams will ensure the Remedial Priority System meets legislated objectives and supports a broad, scientific understanding of site risk. Our goal is to include participants from varied backgrounds, perspectives, and disciplines to support a comprehensive review of current methodologies, potential improvements, and future direction.

Notice of Public Meeting

Development of the Remedial Priority System (RPS) system was mandated pursuant to N.J.S.A.58:10-23.16 as amended in section 39 of P.L.2009, c.60 (Site Remediation Reform Act). A system has been developed to measure each site's relative risk to human and ecological health. The system will be enhanced as new data, improved logic and additional capabilities become available.

A public meeting is scheduled for May 24, 2010 from 9:00 am to 11:30 at the Public Hearing Room in the Department of Environmental Protection Headquarters at 401 East State Street, Trenton to explain the system and demonstrate the technologies and rationale behind the development of the system. Department staff will describe the system in detail and address questions and comments. The Department will also set up a procedure to establish stakeholder groups to work with the Department to review the underlying technology and rationale of the RPS, test the system and ground truth the data used in the system. Recommendations will facilitate responsible use of data and the application of sound science. Parallel to this effort, the Department will solicit current site characteristics from responsible parties to ensure a solid basis for categorizing sites.

Background

RPS models potential risk and is unique in its focus on automation and use of electronic data. Geographic information systems (GIS) and database technologies are used to analyze potential source and receptor relationships. Digital mapping and data representing site conditions provide the foundation for this effort. Immediate benefits include rapid categorization of sites based on the most current information and the ability to evaluate complex human and ecological systems.

The system relies on input data and assumptions much like other systems. All sites are considered objectively using the same criteria. The model will be continuously enhanced through additional data inputs and continued calibration through feedback. Constant improvement ensures inaccuracies are eliminated and the closest approximation to actual site conditions is achieved. Site risk may be revised as new verifiable data is incorporated into the model.

The release of the RPS will occur in stages to ensure accurate categorization of sites. This first version of the system is a work in progress; as new data is acquired and new data systems are brought on line, the system will be updated. A Remedial Priority System Briefing document describing the construction and functionality of RPS is provided below.
