§ 24-37. IAPMO listing and UPC certification mark required.

(a)

No person, firm, corporation or other entity shall sell for use in Sonoma County, install, or cause or allow such sale or installation of any septic tank (or container amenable for use as a septic tank but used as a sump, water tank or other water-tight receptacle) in Sonoma County after July 1st, 1989, that is not listed with the International Association of Plumbing and Mechanical Officials (hereinafter "IAPMO") as meeting the PS-1 design standard (or its successor) for septic tanks. Each septic tank sold for use in or installed in Sonoma County after July 1st, 1989 must bear the Uniform Plumbing Code certification mark which is provided by IAPMO to septic tank manufacturers in good standing. If an IAPMO listing is revoked, septic tanks of the revoked design manufactured on or subsequent to the revocation date shall not be sold for use in or installed in Sonoma County until the IAPMO listing for the revoked design is reinstated. A UPC certification mark upon a septic tank will be regarded as conferring IAPMO approval of the design if the IAPMO listing was revoked after the septic tank's manufacture. Such tanks shall be presumed to meet the PS-1 design standard (or its successor).

(b)

For purposes of this and succeeding sections, a septic tank is a water-tight receptacle which receives the discharge of a drainage system or part thereof, designed and constructed so as to retain solids, digest organic matter through a period of detention and allow the liquids to discharge into the soil outside of the tank through a system of open joint piping or a seepage pit meeting the requirements of the Uniform Plumbing Code.
