CO US PLUMBING/MECHANICAL ADVISORY BOARD c a Fl Cf 4 " Christi MINUTES OF THE REGULAR MEETING ��' 2 June 8,2000 2Z LZ 0Z6N8� Board Members Present: Ronald Klepac, Vice Chairman Nick Llanes Sam Beecroft Clarence Neal Herman Johnson Bud O'Bryan Robert Knowles Patrick Scarpulla Board Members Absent: Ralph Pitzer, Chairman Abey Flores Staff Members Present: Lelland Kirbow, Chief Plumbing/Mechanical Inspector Elizabeth K. Butler, Executive Secretary The meeting was called to order at 2:09 p.m., in the Legal Department's Conference Room. The first item of business was roll call. Mr. Pitzer and Mr. Flores were absent. A motion was made, seconded and approved unanimously to excuse Mr. Klepac and Mr. Beecroft from the previous meeting. The minutes of the February 10ih meeting were approved as submitted. The next item was the discussion of the adoption of the 2000 International Fuel, Gas, Plumbing and Mechanical Codes starting with Chapter 1-Administration. Mr. Kirbow stated that we do not adopt the Chapter 1 in the standard code. We are still short one member the home builder, Mr. Ansler decided not to serve, please keep that in the back of your mind in case you know of anyone interested in being on the board. He explained the marking on the hand out. He stated that there will be more added to this draft. Our target date is October for all the codes. We just adopted the 1997 but we are trying to get on line so that when they come out with a new code. The amendments will be on the intemet or you will be able to get it here. Members will be given the codebook and the amendments. One other thing that is being considered that you will not be involved in is the permit fee increase but that is done by the council but the Building Official wanted you to be aware of this. What he wants is for everyone to study it at length and we will discuss it in full at our next meeting. Under pending and/or old business Mr. Scarpulla asked about the status of on line permitting. A discussion followed concerning shorting the time you need to wait when you come in to get a permit. The board also discussed the possibility of changing the permitting process. They discussed having different days or hours for contractors and homeowners to get SCANNED P.O.
