PASSED BY THE COUNCIL OF THE CITY OF KENAI, ALASKA, this 20th day of October, 2010. ATTEST: Carol L. Freas, City Clerk PAT PORTER, MAYOR New Text Underlined [DELETED TEXT BRACKETED] Introduced: October 6, 2010 Adopted: October 20, 2010 Effective: November 20, 2010 eke u'ty KENAI, ALASKA MEMO: TO: Rick Koch, City Manager FROM: Wayne Ogle, Public Works Director DATE: September 28, 2010 Rick, Village with a Past, Gc with a Future 210 Fidalgo Avenue, Kenai, Alaska 99611 -7794 Telephone: 907 283 -7535 FAX: 907 283 -3014 lilt 1992 SUBJECT: ORDINANCE NO. 2514 -2010; CHANGES TO LOCAL AMENDMENTS TO THE NATIONAL ELECTRIC CODE 2008 This memo is in support of Ordinance No. 2514 -2010 which will restore subsection 334.10(3) of the National Electric Code 2008. The City had adopted the National Electric Code 2008 in April 2009. However, through local amendments, subsection 334.10(3) of the National Electric Code 2008 was not adopted by the City. This was consistent with the City of Anchorage which also deleted paragraph 334.10(3) by local amendment in their adoption of the National Electric Code 2008. The City's deletion of subsection 334.10(3) of the National Electric Code 2008 prohibited the use of non metallic cable in certain types of commercial construction known as Type III, IV V construction, a type of construction made of wood or other combustible materials. The use of non metallic cable is presently permitted for use in residential structures where it is deemed to be safe and sufficiently protective of public health and safety. The Building Official recommends that City restore subsection 334.10(3) to permit the use of non metallic cable in Type III, IV and V commercial construction. He believes that this non metallic cable is among the most inexpensive and readily available wiring methods. He also believes that this will not compromise public safety where it is properly installed in accordance with section 334.10(3). The City's inclusion of subsection 334.10(3) in the National Electric Code 2008 by ordinance will make the City consistent with the State of Alaska.
