Emergency Burn Ban In Effect 10/26/24 - An emergency burn ban is now in effect for all Connecticut State Parks, Forests, and Wildlife Management areas, prohibiting the use of all outdoor grills, firepits, and campfires, and the kindling and use of flame outdoors. DEEP and local agencies are working to contain several active fires across the state. Please avoid all affected State Parks and Forests, as well as the blue-blazed Mattabesett Trail. The Enduro Trail in Voluntown and portions of North Stonington within the Pachaug State Forest are closed at this time. Please note that today's forest fire danger report remains at an 'extreme' level. More information about the current fire danger, burn ban and recommended safety measures can be found here

Reclassification of Southwest Connecticut to severe nonattainment for ozone; impacts to synthetic minor status under RCSA §§ 22a-174-33a and -33b: On October 7, 2022, pursuant to federal Clean Air Act (CAA) § 181(b)(2), the U.S. Environmental Protection Agency (EPA) issued a final rule (87 FR 60926) to reclassify three Southwest Connecticut counties from “serious” to “severe” nonattainment for the 2008 National Ambient Air Quality Standard (NAAQS) for ground-level ozone. This rule became effective on November 7, 2022. Click here for more information. Addition of 1-Bromopropane to the List of Federal Hazardous Air Pollutants: On January 5, 2022, the U.S. Environmental Protection Agency (EPA) published a final rule in the Federal Register adding 1-bromopropane (1-BP), also known as n-propyl bromide (nPB), to the list of hazardous air pollutants (HAPs) pursuant to section 112 of the Clean Air Act. This action was taken in response to petitions filed by the Halogenated Solvents Industry Alliance and New York State Department of Environmental Conservation. The final rule is available at (87 FR 393) and was effective as of February 4, 2022. Click here for more information. Hard and Decorative Chromium Electroplating and Chromium Anodizing Tanks MACT: On September 19, 2012, EPA issued final rule amendments to the Hard and Decorative Chromium Electroplating and Chromium Anodizing Tanks MACT under EPA's residual risk and technology review. The rule sets more stringent emission limits, housekeeping practices, and other new requirements. The housekeeping practices came into effect on March 19, 2013, and can be found here.

EPA Regulation Navigation Tools

EPA has created Regulation Navigation (Reg Nav) tools to help owners and operators of facilities in certain industries determine the requirements of specific regulations. Reg Nav tools are online and interactive, and use the information entered to assess potential regulatory requirements. Reg Nav tools are available for the following regulations:

National Emission Standards for Hazardous Air Pollutants (NESHAPs)

Navigation Tool: Portland Cement Manufacturing Industry

Regulation: Subpart LLL

Navigation Tool: Reciprocating Internal Combustion Engines (RICE)

Regulation: Subpart ZZZZ

Navigation Tool: Brick and Structural Clay Products Manufacturing

Regulation: Subpart JJJJJ

New Source Performance Standards (NSPS)

Navigation Tool: Stationary Compression and Spark Ignition Internal Combustion Engines

Regulation: Subpart IIII & Subpart JJJJ

*Note: Regulation and Navigation Tools open in a new window.

Presentations

Reciprocating Internal Combustion Engines (RICE)

Title: Stationary RICE Regulations in Connecticut

Presenter: Michael LaFleur (DEEP) | 6/12/2013

Description: Presentation covers the CT definition of emergency engine, and the differences between Federal and State emergency engine requirements and limits. As well as, New Source Review (NSR) permitting requirements for RICE, Non-emergency RICE (22a-174-42) and emergency RICE (22a-174-3b and/or 22a-174-3c) and NOx control requirements (22a-174-22).

Title: EPA Air Quality Regulations for Stationary Engines

Presenter: Melanie King (EPA) | 6/12/2013

Description: Presentation covers NESHAP for Stationary Reciprocating Internal Combustion Engines (40 CFR part 63 Subpart ZZZZ), New Source Performance Standards for Stationary Compression Ignition (IC) Internal Combustion Engines (ICE) (40 CFR part 60 Subpart IIII) and NSPS for Stationary Spark Ignition (SI) ICE (40 CFR part 60 Subpart JJJJ). Visit EPA's Region 1 RICE webpage for more information.

Training Modules

Area Source Boiler Rule Online Training Modules

Description: On December 20, 2012, EPA finalized changes to Clean Air Act standards for area source boilers (NESHAP 40 CFR 63, Subpart JJJJJJ). Subsequently, DEEP has created a series of online training modules designed to help owners/operators of boilers, at area sources, determine the requirements they must fulfill in order to comply with the area source boiler rule.

Area & Major Source - RICE Rule Online Training Modules

Description: On January 30, 2013, EPA finalized changes to Clean Air Act standards for stationary reciprocating internal combustion engines (RICE) (NESHAP 40 CFR 63, Subpart ZZZZ), of all sizes, located at area and major sources. Subsequently, DEEP has created a series of online training modules designed to help owners/operators of stationary RICE determine the requirements they must fulfill in order to comply with the RICE rule.
