Re: Revision to the Connecticut State Implementation Plan to 

Limit the Sulfur Content of Fuels Oils Burned in Stationary Sources 

Dear Mr. Conroy: 

This package is a revision to the State Implementation Plan (SIP) concerning the sulfur content 

of fuel oils burned in stationary sources. Pursuant to 40 CFR 51 , Appendix V, Section 2.l(a) a 

copy of the final regulation and documentation of the public hearing are provided. The adoption 

of this proposal completes a commitment made in Connecticut's Regional Haze SIP. 

In addition to the submission of the new requirements into the SIP, the Connecticut Department 

of Energy and Environmental Protection (DEEP) requests the withdrawal of Consent Order No. 

7019A, which was submitted to you as a SIP revision on July 1, 2004. 

Effective April 15, 2014, DEEP adopted section 22a-l 74-19b of the Regulations of Connecticut 

State Agencies (RCSA), which includes fuel sulfur content restrictions for distillate, residual, 

kerosene and aviation fuels used in all non-mobile equipment such as boilers, turbines and 

engines. These new fuel sulfur content restrictions replace the less stringent fuel sulfur content 

limits that were contained in RCSA section 22a-l 74-19 prior to April 15, 2014. DEEP also 

made minor clarifying revisions to RCSA sections 22a-l 74-5(a) and 22a-l 74-19a and added an 

allowable test method to RCSA section 22a-174-5(b )(1 ). All of these revisions are elements of 

this SIP revision and are included in Attachment A. 

All required state and federal procedures for public participation were followed, including 

satisfaction of the requirements of 40 CFR 51 , Appendix V, Section 2. To demonstrate 

satisfaction of the federal public participation requirements, we have enclosed a certified copy of 

the regulatory revisions; the public notice; a list of attendees at the public hearing; certification 

of public hearing; and a hearing report, which summarizes comments received, identifies the 

commenters and describes changes made as a result of the comments. DEEP has the necessary 

legal authority to adopt and implement such requirements. 

Consent Order No. 7019 A was issued to the Hamilton Sundstrand division of United 

Technologies on October 3, 2003 and limits the fuel sulfur content of fuels burned in certain 

boilers at the Windsor Locks facility. The fuel sulfur limits in this consent order are less

stringent than those in RCSA section 22a-174-19b; therefore, the consent order is no longer 

necessary. For your reference, a copy of Consent Order No. 7019A is included as Attachment G. 

The following attachments are included with this letter:
