DIVISION 30
ADOPTION OF A UNIFORM TSUNAMI WARNING SIGNAL


104-030-0000
Purpose
(1) The rules in this division seek to establish a Uniform Tsunami Warning Siren Signal for the Oregon coast (Oregon Senate Bill 557, Section 2).
(2) The objective of the tsunami statutes and these implementing rules is to reduce the risk of loss of life. Risk will be reduced by applying a uniform siren signal to inform the public of an approaching tsunami on the Oregon coast.
(3) Establish a Uniform Tsunami Warning Siren Signal standard.
(4) Require tsunami warning sirens to adhere to this standard.

Applicability
(1) This rule applies to all Tsunami Warning sirens, including existing Tsunami Warning sirens.
(2) Existing Tsunami Warning sirens must comply within 5 years of the effective date of these rules.
(3) The siren signal is the “wail,” a siren tone that oscillates up and down repeatedly from high to low over a period of three minutes.

Definitions
(1) “Tsunami Warning Siren signal” is the wail, a siren tone that oscillates up and down repeatedly from high to low over a period of three minutes.
(2) "Tsunami inundation zone" for the purpose of these rules means the area subject to tsunami inundation as depicted on maps adopted under OAR 632-005-0030 of these rules and intended for the implementation of ORS 455.446 and 455.447.
(3) A “Tsunami Warning Siren” is a siren or other audible warning device for the purpose of providing warning to the public within the Tsunami Inundation Zone of an approaching tsunami.

A rotating siren using a solid tone that produces the same effect as a fixed siren using a “wail” when observed from a stationary location and meets the intent of these rules.

Guidance on Testing
(1) The siren test time is designed to roughly coincide with the weekly National Oceanic and Atmospheric Administration (NOAA) Weather Radio tests. Tsunami Warning Sirens will be tested on Wednesdays at 11:00 hours (a.m.) for routine testing of tsunami warning systems. Testing will be done on the first Wednesday of each month at 11:00 am.
(2) The recommended siren test duration is not to exceed 60-seconds excluding voice message, except during system coverage evaluations, unless using a unique sound for the test, such as Cows or Chimes.
(3) A sign or placard shall be affixed to each siren stating the routine test time and day.
