**Boiler Rule Update – March 2014**

In order to comply with the boiler rule, affected organizations must file the required documents with both the Environmental Protection Agency (EPA) and Tennessee’s Air Pollution Control Division.  As of January 1, 2014, EPA requires all Notifications of Compliance Status to be submitted electronically using the Compliance and Emissions Data Reporting Interface (CEDRI), part of EPA’s Central Data Exchange (CDX).

TN Air Pollution Control recently received access to the EPA system.  As such, organizations only need to submit their Notification of Compliance Status electronically through CEDRI to the EPA.  Organizations do not need to mail, email or fax a copy to TN Air Pollution Control, as indicated on the forms mailed by the Small Business Environmental Assistance Program.

For questions or concerns about this or any other matter related to the boiler regulations, please contact Ali Mohsenzadeh.

**Rules for Entities with Boilers**

The Environmental Protection Agency (EPA) issued a revised rule in an effort to reduce emissions of toxic air pollutants from existing and new boilers. Referred to as the National Emission Standard for Hazardous Air Pollutants for Industrial, Commercial, and Institutional Boilers at Small/Area Sources (40 CFR Part 63, Subpart JJJJJJ), a copy of the rule is available at

According to the EPA rule, all facilities (except those located in Davidson, Hamilton, Knox, or Shelby counties) with a boiler that burns coal, oil, or biomass must take the following actions (based on size, fuel, and date of the construction of the boiler) and file relevant paperwork:
