Building Official,
This antenna modification package we are submitting for a building permit is located on an
existing Snohomish County PUD (SnoPud) structure at the above address. We are submitting
this letter as support documentation that a structural analysis will not be provided by the utility
company. Please see the exemption detail below.
SnoPud will be responsible for developing the design loads for the structure and performing the
design of the structure which includes all equipment mounted on the structure including the
WCF equipment per the Washington Administrative Code 296-46, the National Electric Safety
Code (NESC) and electric utility standards and practices. The analysis will use WCF antenna
loads and design provided by T-Mobile.
Utility structures have long been exempt from the Uniform Building Code (UBC) under section
101.3 of the 1997 code and the change to the International Building Code (IBC) has not
eliminated that exemption. Public utility structures are specifically exempt from the provision
of the IBC and as such design calculations are not required to be provided to the permitting
agency. SnoPud's construction personnel or other designated qualified electrical workers will
be responsible for any work on the structure in and above the electric supply space which
involves work such as electric lines, equipment modifications, installation of a new pole and/or
installation or maintenance of antennas and cable. The new or modified structure shall
continue to be under the ownership of SnoPud.

Should you have any further questions regarding this exemption, please let me know.
Sincerely,
