  2. What Is An IC? • Non-engineered administrative or legal controls that limit land or resource use and/or protect the integrity of a remedy

  3. When Are ICs Used? • Used when contamination is first discovered to limit exposure • Used during cleanups • Used when residual contamination is left in place after site cleanup

  4. The Problems • ICs may be called for by EPA but they tend to be implemented by others • Sometimes ICs called for by EPA cannot be implemented (i.e., zoning in an unincorporated area) • There is no easy way to communicate information on ICs

  5. The Vision • EPA will provide leadership to facilitate the exchange of information on ICs among the different parties managing the ICs and the public • Development of data standards is part of this • Mapping of ICs is important for visualization • A tracking system for ICs that can pull the information together

  6. Drivers for National Institutional Controls • IC necessary when waste left in place and media affected cannot support unrestricted/unlimited use. • CERCLA requires remedies remain protective, and where waste left in place be reviewed no less often than every five years. • Recognize ongoing GAO investigation—we need to make progress!

  7. Original Data Tiers for ICs Tier 1 Tier 2 Tier 3 Does the site have an IC? [yes/no] Information on IC, implementation, monitoring, and enforcement. Tier 2 plus, site specific GIS maps of the ICs and surrounding geographic features. Significant economies and superior reporting-- no need to repeatedly seek out documentation. Easier to set up but repeated document searchefforts All data reported will have source (e.g., NY), date of reporting to EPA, and other attribute information (e.g., data quality) as appropriate.

  8. Progress--IC Tracking • EPA has worked with stakeholders and within EPA to establish a registry and proposed an IC standard (comment period to close by the end of September) • Data collection efforts have focused on basic information that EPA has (Tier 1) • The ICTS receives data through CDX, which can easily add States, Tribal, and local governments as well as responsible parties

  9. GIS and ICs • While EPA has not been systematically collecting GIS information related to ICs, such data exists both within EPA and with EPA contractors. • GIS data is used to track cleanup progress • GIS data is used to communicate with the public • However, EPA has not yet established a polygonal standard.

  10. GIS Issue • Every day that goes by, EPA continues to conduct work and if we believe that we will be seeking GIS information • Suggest obtain deliverable in an electronic format when possible—expect reformatting to be much cheaper than new collection of information from contracts that may be closed

  11. Data Quality—Some thoughts • Each data element will have attributes by program (e.g., state, local, other) • Data reported will include information on the source of the information and when the information is updated • Data submitted can go through automated and staff reviews before it is added to the tracking system • Data that is replaced with newer data will be retained in a backup system so that it could be used for either recovery or comparison purposes • System input screens will use pull down menus to reduce the potential for incorrect choices and typing errors

  12. Assistance Requested • Available SOPs that automate GPS mapping that could be used for mapping institutional controls and residual contamination • Recommendations on equipment for mapping (along with information on confidence and uncertainty specifications) • Look to products of Geospatial Quality Council and others…

  13. Conclusion • We have a production tracking system in the RTP production environment that relies upon CDX for input output • We have completed data collection for construction completion sites and are in the process of QA • Data standards for ICs cover the data with the exception of GIS data • GIS is the next likely significant area of development for IC tracking that we will be exploring
