New 2016 Federal Reporting Requirements For Owners of Emergency Engines

Owners of emergency engines with a maximum engine power of more than 100 horsepower (HP), which are operated or contractually obligated to be available more than 15 hours/year for emergency demand response, voltage or frequency deviations, or local reliability (as specified in 40 CFR §63.6640(f), §60.4211(f), and §60.4243(d)), must now submit an annual report to U.S. EPA.

The report, due March 31, 2016, is to be submitted electronically through the Compliance and Emissions Data Reporting Interface (CEDRI), accessed through U.S. EPA’s Central Data Exchange. It must cover the prior year’s operations and include the information specified in 40 CFR §63.6650(h) (for stationary emergency RICEs), §60.4214(d) (for compression ignition engines), or §60.4245(e) (for spark-ignition engines). More information on the report is available on U.S. EPA’s Stationary Internal Combustion Engines page.

Changes Affecting Emergency Planning and Community Right-To-Know Act (SARA Title III) Reporting

Effective July 1, 2015, Senate Bill 484 transferred the responsibility for administering Indiana’s reporting program under Title III of the federal Superfund Amendments and Reauthorization Act of 1986 (SARA Title III) from the Indiana Department of Environmental Management (IDEM) to the Indiana Department of Homeland Security (IDHS). All Hazardous Chemical Inventory/Tier II reports are now due to be submitted to IDHS [PDF], beginning January 1, 2016.

In addition, IDHS has developed Tier 2 Manager, a new online portal designed to act as a unified reporting, notification, and fee payment system. Facilities no longer need submit separate Tier 2 reports to ISDH, the Local Emergency Planning Committee (LEPC), and the local fire department and can pay their Hazardous Chemical Inventory Fee (HC-500) through Tier 2 Manager via credit card or e-check.

IDHS is conducting workshops [PDF] on the new reporting system. Interested parties should RSVP to the appropriate workshop contact.
