Conn. Gen. Stat. § 7-572
Any municipality that desires to issue general obligations under section 7-573 shall apply to the secretary for certification or designation. The secretary may certify as a tier I municipality any municipality which applies to be certified, provided such municipality (1) has a long-term bond rating from at least one bond rating agency which is investment grade or higher, (2) is unable to secure municipal bond insurance from any bond insurance company on reasonable terms and conditions on the date the secretary certifies such municipality, and (3) otherwise meets the standards established by the secretary. Such standards shall be established in writing by the secretary, after consulting with the Treasurer, shall provide for a level of supervision over such municipality which the secretary deems to be sufficient to minimize the risk of a draw upon the special capital reserve fund and a transfer from the state General Fund and shall be posted on the Internet web site of the Office of Policy and Management. The secretary may recertify and decertify any municipality then certified, provided the secretary shall not automatically decertify any municipality which is able to secure bond insurance after it has been certified by the secretary.
