. >> my name is dave fehee and i am with local 38 plumbers and pipe fitters union. i'm also a member of the mayor's zero emission task force and some of the commercial work groups. i've been involved from the first meeting up until today. let's start by recognizing the supervisors of the land use and transportation committee for their committed support and consideration. i would also like to applaud the ordinance sponsor supervisor mandelman and his staff and all the associated san francisco agencies that have continued to work their efforts for an equitable transition, including present-day participation just mentioned with the work sessions. it is attributed to the workforce, the citizens, and the future. i would like to recognize the environmental groups that continue to work with us, it is greatly appreciated and all the callers who have supported the water reuse and conservation, through calgreen and other sustainable goals. we've been using the metaphor along the way as the electrification ordinance due to its complexity as a plane which we're trying to land.
