Data Exchange CDX

EPA has proposed electronic filing regulations and if these go into effect then requests for determinations of equivalency filed after the effective date must be made using the ePMN software, and may be filed on paper, through CD, DVD, or EPA s Central Data Exchange (CDX) for one year after the effective date of the new rules, and thereafter must be submitted via CD, DVD, or CDX for the next year, and then only through CDX. ... 

The idea is to provide one way and one place for the regulated community to exchange electronic documents with EPA. The CDX may also provide the platform for State-EPA data exchanges. As with the provisions of the proposed rule, the features and functions of CDX described above will generally be inapplicable to these State-EPA exchanges.
