Enforcement and Compliance History Online (ECHO) is a tool developed and maintained by EPA's Office of Enforcement and Compliance Assurance for public use.

QIDs are time sensitive and will be valid for approximately 30 minutes. 2) Use get qid, with the returned QID, to paginate through arrays of facility results. 3) Use get map, with the returned QID, to zoom in/out and pan on the clustered and individual facility coordinates that meet the QID query criteria. 4) Use get download, with the returned QID, to generate a Comma Separated Value (CSV) file of facility information that meets the QID query criteria.
