Minnesota Pollution Control Agency Minnesota Pollution Control Agency https://gisdata.mn.gov/dataset/env-mpca-remediation-sites 20190823 This dataset represents the locations, classifications, and physical characteristics of remediation activities carried out by the Minnesota Pollution Control Agency. The locations represent leak clean up, emergency response, petroleum brownfields, non-petroleum brownfields (Voluntary Investigation and Cleanup), Superfund, RCRA, integrated remediation and site assessment sites. The geodatabase, env_remediation_sites.gdb, contains two related datasets: (1) the <a href="remediation_sites.html">remediation_sites</a> point feature class, which has one record for each remediation site, and (2) the <a href="spatial_rem_activity.html">spatial_rem_activity</a> table, which contains one record for each MPCA effort to investigate contamination at a site. The two datasets can be related using the ITEM_ID. In most cases, there will be one record in spatial_rem_activity for each record in remediation_sites. However, reopened leak sites may have multiple records in spatial_rem_activity for a single site, and CERCLIS/SEMS sites where the EPA was the lead agency may have zero records in spatial_rem_activity. The spatial_rem_activity table only exists in the file geodatabase format of this dataset. The attributes and locations of remediation sites provide information and context to support decisions on environmental cleanup, emergency management, and maintaining environmental quality. These data are intended to inform environmental research and public inquiries. These data are refreshed daily and pushed out to the Minnesota GDRS and the Minnesota Geospatial Commons.

St. Paul MN 55155 datadesk.mpca@state.mn.us spatial_rem_activity OBJECTID Internal feature number ESRI ITEM_ID The unique ID that defines an item. master_ai_id + '-' + subject_item_category_code + subject_item_id AI_ID Tempo database Agency Interest ID. This represents a single property; multiple remediation sites can exist at one Agency Interest. PROJECT_ID The MPCA or EPA cleanup site ID. SI_CAT subject_item_category_code. SI_ID subject_item_id. A numeric database identifier for internal database tracking. ACTIVITY_ID Combined with the item_id, this will uniquely identify an investigation project that involved this site. In most cases, there is one ACTIVITY_ID for each SITE_ID. However, in the case of a reopened Leak site, there may be multiple activities. ACTIVITY_TYPE_DESC Description for the kind of activity or investigation project. ACTIVITY_CLASS_CODE Activity class code ACTIVITY_YEAR The year the activity was created in the Tempo database. ACTIVITY_NUM Internal auto-ID that counts, for a given ai_id, activity_category and activity_year, the order in which activities were created. LEAK_DISCOVERED Date the leak was discovered LEAK_REPORTED Date the leak was reported LEAK_REOPENED Earliest date that a closed leak site was reopened. RECEIVED Date that a Brownfields application was received; may also indicate a start date for other projects SITE_CLOSED Date this site was closed NPL_LIST Date this site was listed on the National Priorities List (the federal Superfund list) NPL_DELETE Date this site was deleted from National Priorities List (the federal Superfund list) PLP_LIST Date this site was listed on the Permanent List of Priorities (the state Superfund list) PLP_DELIST Date this site was delisted from the Permanent List of Priorities (the state Superfund list) FF_APROVED Fund Finance Approved FF_CLOSED Fund Finance Closed INV_COMPLETED Investigation Completed REMEDY_IMPLEMENTED Remedy Implemented REMEDY_SELECTED Remedy Selected ASMT_COMPLETED Assessment Completed SITE_START Date this project started. Calculated based on the earliest date among these fields: staff_assigned, discovered, er_site_eval, leak_reported, received, leak_reopen, app_completed. DISCOVERED Earliest date of discovery. STAFF_ASSIGNED Date staff were first assigned to this site. APP_COMPLETED Earliest date that an application to participate in this program was reviewed. ER_SITE_EVAL Earliest date that emergency response staff evaluated site conditions NFA_DECISION No Further Action Decision Remediation sites from the Minnesota Pollution Control Agency's enterprise database.

St. Paul MN 55155 datadesk.mpca@state.mn.us This dataset has been exported from the MPCA's enterprise database (Tempo) and reflects our knowledge of these features at the time of export. MPCA Remediation programs started using the Tempo database on April 25, 2016. Data from before that date were migrated from the TALES and SRS databases. Some data are incomplete for migrated sites, PCA staff are working on correcting that. (2017 - 2018) Universal Transverse Mercator 15 meters NAD83 GRS80 20260403 02013700 1.0 TRUE
