To protect the public health, the Snohomish Health District Board of Health does, for the sake of clarity, adopt the following additional statement to WAC 246-272A-0010(2) for the definition of “on-site sewage system”:

However, relative to the creation of new lots, all such piping, treatment devices or other facilities that convey, store, treat or dispose of sewage, including replacement systems, shall be located within the boundaries of the lot where the sewage originates.
