Idaho Facility Mapper

The Facility Mapper is the map tool of the Idaho Department of Environmental Quality (DEQ) for sites managed by its Waste Management and Remediation programs. DEQ says those programs oversee sites that generate or manage wastes, or that have released wastes into the environment and require remediation, and that the sites are shown on the Facility Mapper by regulatory program. DEQ says the tool is hosted by a third party and is meant to help the public, local governments and environmental consultants find the location and details of sites.

In a Phase I ESA

ASTM E1527-21 does not name the Facility Mapper among its standard record sources. It is one search that reaches several of the Idaho records the standard does name. The categories DEQ lists for it are:

DEQ also says the tool includes information on sites with activity and use limitations in the form of environmental covenants.

Five things DEQ says about the tool shape how far to rely on it.

• Some sites are left out. DEQ says sites involved in a permitted activity or requiring remediation are included. It says older sites with small incidental releases, and sites that lack sufficient location information, may not be included.
• Some sites are not on the map. DEQ says its records do not provide location information for some sites, and that unmapped sites can be identified through the Advanced Search tool. Run that search as well as the map search.
• There is a radius search. DEQ says the Radius Search lets the user select, create and download lists of sites within a specific radius of an address the user gives.
• The data is refreshed about twice a month. Note the date of the search in the report.
• DEQ does not warrant it. DEQ says the tool is provided for informational purposes only, and that it makes no guarantee or warranty of the accuracy or comprehensiveness of the information. Confirm what matters against the file.

What the record shows

DEQ says that once a site is selected, the Feature Information tab lists the programs implemented at the site with basic program identification and contact information. For a site with UST facilities, the UST hyperlink leads to the UST-LUST database. The tab gives direct access to a site's environmental covenant documents.

Where to look a site up

• DEQ's Facility Mapper page explains the tool and carries a link for each regulatory program.
• The tool itself is linked from that page under the name Facility Mapper Tool.

Getting the file

DEQ says that when more information on a site is needed, the tool provides a link to DEQ's public records request form. DEQ's Public Records Request page carries the buttons to submit a request online, track its status and search the request archives. That page lists the Facility Mapper among the resources that can often answer a question without a formal request.
