<prompt> Translate the following text to EnglishKwa kuzingatia vipindi vya muda vinavyohitajika kukamilisha kila moja ya hatua nne zilizoelezwa hapo juu, kipindi cha muda kinachohitajika kukamilisha utekelezaji wa ACI kwenye kitengo kimoja cha kuchoma ni karibu miezi 15, kama inavyoonyeshwa katika Kiolezo A-5 katika Nyongeza A. Kwa kuwa mchakato wa kutoa ruhusa hupunguza muda, mchakato wa kutoa ruhusa ya haraka utapunguza muda unaohitajika kuanzisha ACI kwenye kitengo kimoja.  <response>: Based on the estimated time periods needed to complete each of the four phases described above, the estimated time period to complete the implementation of ACI on one combustion unit is about 15 months, as shown in Exhibit A-5 in Appendix A. Since the permitting process limits the timeline, a faster permitting process will shorten the time necessary to install ACI on a single unit.
