Sites that are the subject of a cleanup report submitted to DEQ.Sites with documented contamination that are eligible for the Confirmed Release List (Oregon Revised Statute 465.405).(When remediated sites no longer pose risks to human health or the environment, ECSI shows their No Further Action status retaining such sites in ECSI benefits those seeking historical or "case-study" information on sites that have been through the cleanup process.)ĭEQ's Cleanup program adds sites meeting any of the criteria below to the ECSI database: Furthermore, sites can be delisted from the CRL and Inventory following cleanups, but are not removed from ECSI. ![]() In addition, the CRL/Inventory listing process includes a formal notification and comment period before sites are actually listed. Criteria for listing sites on the CRL or Inventory are different from the criteria for adding sites to ECSI. Two Cleanup Program lists, the CRL and Inventory, do carry regulatory significance and should not be confused with ECSI. ![]() The fact that a site is included in ECSI has no regulatory significance per se, because neither Oregon Revised Statutes nor Oregon Administrative Rules refer to ECSI. Once DEQ adds a site to ECSI, the site remains on the database to provide tracking and historical information. Therefore, if you need more details on site history or activities, you should contact the appropriate regional office and schedule a file review. The ECSI database contains only summaries of site information. However, data resulting from this download may not be current (the page indicates the date of the data). The complete ECSI data set can also be downloaded electronically from the ECSI download page. You can also download comma-delimited record sets of data generated from your queries. Queries return a one-line listing of sites meeting the search criteria entered and provide links to detailed reports for each site. This query, which returns up-to-the-minute data in the database, allows you to conduct a search for ECSI sites, as well as for sites on the CRL and Inventory, by criteria you specify, including: ECSI # site name street name or number zip code city county latitude/longitude ranges completed site actions or recorded contaminants. The easiest and quickest way to obtain data from ECSI is to use the ECSI query. There are several ways to access this data, at different levels of detail. DEQ has also created study areas of sites that could threaten Vulnerable Areas such as drinking water sources or streams with endangered fish species. Then, DEQ will add sites within the region’s boundaries to this study area, and these sites may be investigated to determine if they’re potential sources of contamination. For example, when DEQ discovers regional groundwater contamination where the sources of contamination are not known, it will create a study area for this region. Most sites are either industrial or commercial, but the Cleanup Program sometimes adds highly contaminated residential properties to ECSI.ĮCSI also includes study areas, which are groups of individual sites that may be contributing to a larger, area-wide problem. Sites range from urban industrial complexes to isolated rural facilities contaminated by disposals or spills. Some ECSI sites have minimal information available and need an initial evaluation, while others have completed investigative and remedial actions, and have earned a NFA decision from DEQ. What all sites have in common is documented, suspected, or remediated hazardous substance contamination in groundwater, surface water, soil, or sediments. Sites in ECSI comprise a wide variety of sizes, locations, features, contaminant profiles, and degrees of Cleanup Program information. The amount of data entered for each site varies greatly and depends on the nature of site issues, how long the site has been active in DEQ’s Cleanup Program, and the priority DEQ has assigned to the site. ![]() ECSI also lists past and present site operations, owners/operators, and site contacts. ECSI categorizes current site status as either: 1) under investigation 2) on the Confirmed Release List or Inventory of Facilities Needing Further Action (Inventory) or 3) cleaned up to DEQ standards (No Further Action, or NFA). At many sites, ECSI documents contaminants found in soil, surface water, sediments, and groundwater, with associated concentrations and sampling dates. For most sites, ECSI also indicates how and when the site became contaminated, qualitative risks the contamination may pose to human health or the environment, investigative and cleanup actions that have occurred, and prioritized further actions, if any, that are required. Each ECSI entry contains basic data such as site name and location. Action on Climate Change arrow_drop_down.Recycling and Waste Prevention arrow_drop_down.
