For purposes of this paragraph, the multiple year project investment period will be treated as having commenced if the taxpayer has placed the qualified investment into service or use in accordance with section four of this article. A multiple year project period will not be treated as having commenced merely as a result of the issuance of certification of a project under section four-b of this article. No entitlement to any tax credit under this paragraph may result from, and no credit is available to any taxpayer for, investment placed in service or use after closure of the multiple year project investment period for which certification has been issued.
