EPA has explained to companies how they can submit EDSP data to EPA via EPA’s Central Data Exchange. The CDX enables companies to electronically submit data; provides secure exchange of confidential business information or trade secret data; and improves security using digital encryption. All data is encrypted in transit to federal standards (with the exception of voluntary submissions). Sensitive data is encrypted to federal standards. All sensitive data remains encrypted until it is behind at least 2-3 firewalls. Click here to access EPA’s Central Data Exchange website.
