Facilities regulated by the Accidental Release Prevention Program are required to submit and periodically update their Risk Management Plan Registration Form and are subject to annual fees determined by the program.

DNREC has created an online reporting system for Accidental Release Prevention Program users. It is designed to improve the efficiency of the reporting process and give quick access to updated Risk Management Plans.

The ARP/Tier II Reporting System allows users to submit their Risk Management Plans, various reports, fee payments and inspection follow-ups. The system is accessible using typical web browsers. No special software is needed.

ARP/Tier II annual administrative updates and the ARP fee are due by the first day of May each year.

Note: The Tier II Manager system database combines both ARP and EPCRA Reporting Systems. Both reporting systems can be accessed either by a shared EPCRA user or an independent ARP user, as applicable.
