Any period of welfare emergency proclaimed by the Governor pursuant to this section shall commence on the date of the proclamation by the Governor, and shall continue until federal assistance is received by this state for joint public assistance for the first quarter following the date of the proclamation, or until the commencement of the second quarter following that date, whichever first occurs. In no event shall any period of welfare emergency continue for more than four calendar months, nor shall any subsequent period of welfare emergency be proclaimed unless federal assistance has been received by this state for each prior fiscal quarter commencing during any prior period of welfare emergency.
