                                                    Central  Data  Exchange

                                The Central Data Exchange (CDX) is EPA's center of excellence for electronic reporting and
                                data exchange via the web and as EPA's point of presence on the Environmental Information
                                Exchange Network.  CDX manages thousands of data transactions with States, Tribes, industry,
                                and other federal agencies through a service oriented architecture. CDX provides standardized
                                and secure information collection services that meet the needs of many EPA Program partners
                                throughout the Agency. CDX will continue to expand, adding more data flows and services to
                                simplify reporting, improve data quality and reduce burden for its customers.
Background
The Government Paperwork Elimination Act
(GPEA) establishes a framework that requires
and promotes electronic reporting when it can
contribute to reduced burden on the public.
CDX is EPA's response to GPEA to help with
this burden  reduction.  In addition, the states
and EPA, recognizing the need for an
information  exchange system to meet the
needs of environmental decision-makers at all
levels, committed to a partnership to build an
environmental data exchange system. EPA
and States proposed the development of the
Exchange Network. The Exchange Network
connects EPA and state environmental
databases over the Web using CDX as EPA's
exchange Node on the Exchange Network.
                                            CDX BENEFITS

                                            • Simplified reporting:  Complete one
                                            electronic form instead of multiple paper
                                            forms.
                                            • Improved data collection: Increased data
                                            quality, timeliness, accessibility, and
                                            security
                                            • Reduced burden:  Reduce time and
                                            resources expended to fill out and process
                                            submissions.
                                            • Reduced costs:  Centralized, shared
                                            services eliminates the need for redundant
                                            data systems and  reduces data collection
                                            and management  costs
                                            • CROMERR Support: Centralized services
                                            to comply with the Cross-Media Electronic
                                            Reporting Rule
Current Status
Over the past two years, CDX has delivered
an average of 110,000 submissions annually
to EPA. Currently, CDX has over 120,000 user
registrations. CDX supports nearly  50
environmental data exchange activities with their electronic reporting and data exchange
needs.  In addition, 20 Programs are currently in varying stages of planning or design for
future deployment.  EPA is also in the process of expanding CDX to support data exchanges
with other federal agencies as well as internationally. The Office of Environmental Information
has continued to drive down the cost reporting and data exchange by making  available
centralized services that can be leveraged by multiple EPA Programs.

On-going Activities
    •   Operating, maintaining and enhancing CDX, and continuing to evolve with new
       technology to provide the most cost effective data flow services
    •   Partnering with States, Tribes, EPA Programs and Regions to implement successful
       information sharing on the Exchange Network;
    •   Deploying new data flows and  services,  such as automated fee collections and
       messaging/alerts subscriptions;
    •   Implementing services that allow for electronic reporting of confidential business
       information; and
    •   Helping system owners comply with the Cross-Media Electronic Reporting Regulation
       standards.
