Conn. Agencies Regs. § 22a-449(d)-111 - Life expectancy

Current through August 18, 2021

(a) This subsection, in conjunction with subdivision 22a-449(d) -104 (b) (2) and subsections 22a-449(d) -104 (a), (c), (d), (e), (f) and (g) of these regulations specifies when a tank tightness test and line tightness test shall be performed, and when the owner and operator shall discontinue use of an UST system component in accordance with section 22a-449(d) -110 of these regulations.
(b) Life expectancy determinations shall be conducted as follows:
(1) Life expectancy determinations shall be conducted for components of petroleum UST systems, the construction or installation of which begins on or after November 1, 1985, including, but not limited to, UST systems which replace UST systems and UST systems which are moved from one location to another, within thirty (30) days following completion of installation or substantial modification of the component; and shall be conducted for components of petroleum UST systems, the construction or installation of which began prior to November 1, 1985, by May 8, 1986; as specified in subsection 22a-449(d) -102 (b) of these regulations.
(2) Life expectancy determinations shall be conducted for components of hazardous substance UST systems, the construction or installation of which begins on or after the effective date of these regulations, including, but not limited to, UST systems which replace UST systems and UST systems which are moved from one location to another, within thirty (30) days following completion of installation or substantial modification of the component; and shall be conducted for components of hazardous substance UST systems, the construction or installation of which began prior to the effective date of these regulations, by 180 days after the effective date of these regulations; as specified in subsection 22a-449(d) -102 (c) of these regulations.
(3) Life expectancy determinations shall not be required for underground vent and vapor recovery piping.
(c) Life expectancy shall be as follows:
(1) For fiberglass-reinforced plastic (FRP) UST system components, the period of the manufacturer's corrosion or structural warranty, whichever is shorter.
(2) For cathodically protected UST system components that meet the requirements of subsection 22a-449(d) -102 (a) of these regulations, the period of the manufacturer's corrosion or structural warranty, whichever is shorter, or the life expectancy of the existing or replacement anode(s) as calculated using standard formulae approved in writing by the commissioner. If the cathodic protection system malfunctions or fails to meet the structure to soil test voltage requirement in subsection 22a-449(d) -103 (b) of these regulations, and is not repaired or replaced within thirty (30) days, the life expectancy of the UST system components protected by the system shall be reestablished in accordance with either subdivision 22a-449(d) -111 (c) (3) or subsection 22a-449(d) -111 (d) of these regulations. If life expectancy shall be reestablished in accordance with subdivision 22a-449(d) -111 (c) (3) of these regulations, the period specified by subdivision 22a-449(d) -111 (c) (3) of these regulations shall be deemed to have begun on the earliest date of malfunction or the earliest date on which the structure to soil test voltage reading was less negative than minus 0.85 volts, as applicable, provided that the period specified by subdivision 22a-449(d) -111 (c) (3) of these regulations shall not extend beyond the last day of the component's initial life expectancy period.
(3) For UST system components not covered in subdivision 22a-449(d) -111 (c) (1) of these regulations and subdivision 22a-449(d) -111 (c) (2) of these regulations, fifteen years from the date of installation. If the date of installation cannot be documented, the life expectancy shall be determined by a method approved by the commissioner in writing.
(d) The life expectancy of an UST system component may be determined by a method other than those set forth in subsection 22a-449(d) -111 (c) of these regulations upon written approval of the commissioner.
