"Institutional Control (IC) polygons were created by Coordinate Geometry (COGO) from recorded Environmental Restrictive Covenants (ERCs) and other Institutional Controls (ICs) mandated by the Indiana Department of Environmental Management."
"This dataset was developed to provide the spatial component of recorded Institutional Controls for managed facilities of the Indiana Department of Environmental Management. When any amount of contamination above a residential closure level is left on site, a legal measure called an Institutional Control (IC) may be needed. An IC protects human health and the environment by restricting property activity, use, or access. As an example, the RISC guidance may allow a site to be remediated only to levels appropriate for industrial or commercial uses. In this case, an IC would be required that would restrict the use of the property to non-residential purposes in the future."
"A corrective action plan was prepared and implemented in accordance with statute(s) IC 13-23, IC 13-24, and/or IC 13-25] and/or other applicable Indiana law as a result of a release of petroleum or regulated substances (collectively, "contaminants of concern") which affected the Real Estate. Certain response activities have been implemented at the Real Estate, e.g., soil removal to remediate specific contaminants in specific areas of the site; placement of engineered cap; remediation of groundwater, etc.
"The corrective action plan, as approved by the Indiana Department of Environmental Management, provides that contaminants of concern will remain in the groundwater and/or in the soil of the Real Estate and requires that land use restrictions that must be maintained to ensure the protection of public health, safety, or welfare, and the environment."

The following is excerpted from the metadata provided by IDEM, OLQ for the source shapefile named "OLQ_INSTITUTIONAL_CONTROLS_IN.SHP":
"All attributes created during the process were verified by displaying the lines in the database and verifying consistency. However, no formal tests were performed. Therefore accuracy cannot be guaranteed or verified."
"Data was compiled by the Engineering & GIS Section within the Office of Land Quality, the Indiana Department of Environmental Management. This dataset is incomplete and a work in progress, sites are COGO'ed as they are received. This dataset contains information that represents what had been recorded, processed, and archived by IDEM personnel at a time previous to publication. However the dataset may be incomplete and/or inaccurate due to the ever-changing status of managed facilities and sites, and due to the data collection and processing efforts of IDEM staff. It is an ever-changing work in progress. The Engineering & GIS section was also responsible for collecting attribute information for each location. The data has been QA/QC'd for consistency but no formal tests were performed on accuracy. Therefore accuracy cannot be guaranteed or verified. Omissions or null values in certain fields are due to the fact that edits were made in the data dictionary (adding or deleting attribute information) as the project progressed. Human error could have been a factor as well in data omissions."
"The referenced point data was collected with a GPS GIS-mapping system. The accuracy of the coordinates for GPS data should be from .5-5 meters, depending upon the type of GPS instrument used, the collection environment (ie., multipath, SNR, and PDOP), and the number of positions logged for each location. However, this accuracy cannot be guaranteed or verified. Each GPS unit should have been configured within the specifications of the manufacturer. However, if necessary, the field personnel would configure the unit outside of specifications if environmental conditions warranted. Accuracy was checked by logging both Maximum PDOP and the standard deviations of the positional average of each location collected. If maximum PDOP value was > 6, the value for the "In_specs" field was input as "NO". If the standard deviation was > 8, the corrected GPS file was analyzed for signs of multipath and/or outliers, and edited accordingly. It was then re-exported to the archive. If the data set was uneditable it was still left in the archive, the "In-specs" field was changed to "No" and the location could have an accuracy > 5 meters.
"The following explanation corresponds to the small traingular polygons used as ERC place markers:
"If the environmental conditions of the collection session fell within the acceptable ranges for data collection as defined by the technical specifications of the instrument used and specific instrument configuration, then the accuracy of the collected coordinates should be within those values as given by the manufacturer. The GeoExplorer Unit has an accuracy range of 2 to 5 meters (post-processed), the GeoExplorer 3 and 3c a range of 1 to 5 meters (post-processed), and the Pro XR has a range of .50 cm - 1m differential accuracy to real-time differential correction.
"If the environmental conditions and/or technical configurations were not met, then the values could exceed those given by the manufacturer.
"The following explanation corresponds to the polygons that are COGO'ed in using the recorded ERC Exhibit A:
"The recorded ERC Exhibit A (Legal Description of Real Estate) was based on original recorded surveys. The original descriptions may have been modified outside of IDEM's control, therefore the accuracy is unknown. The quality control step that IDEM personnel used is that the digital polygon closed (no accuracy is guaranteed or implied)."
"The vertical accuracy for GPS data collection can be two to three times less accurate than horizontal accuracy. The vertical accuracy for these locations could have up to 15 meters of error. However, this accuracy cannot be guaranteed or verified. Height above Ellipsoid values have been recorded, but it is strongly suggested that the values not be used for any analysis.
"Due to the nature of how these values are derived in the GPS data collection process, the error variable is large enough to make the coordinate values unuseable in any type of locational analysis.
"The following explanation corresponds to the polygons that are COGO'ed in using the recorded ERC Exhibit A:
"The recorded ERC Exhibit A (Legal Description of Real Estate) was based on original recorded surveys. The original descritions may have been modified outside of IDEM's control, therefore the accuracy is unknown. The quality control step that IDEM personnel used is that the digital polygon closed (no accuracy is guaranteed or implied)."
"Small triangular polygons representing points were created representing the portion of this dataset that have not been COGO'ed yet, or did not have sufficient data to be COGO'ed. These triangular polygons were digitized using heads-up digitizing over the facilities point layer at a scale of 1:2,000 when the point was displayed at a size of four (circle2 symbol). COGO'ed descriptions from recorded ERCs Exhibit "A" represent the other portion of this dataset."
This data set is ongoing and ERCs that have not been COGO'ed, or do not have sufficient data to complete the COGO process, are represented by small triangular polygons.
The ERC polygon attributes are correlated and attached with the fields from the IDEM Institutional Controls Registry database.
