MATERIAL AND PROPERTY STANDARD FOR GREASE INTERCEPTORS AND CLARIFIERS
Grease interceptors shall be designed to remove grease from effluent, and shall be sized in accordance with Appendix H of the UPC. Grease interceptors shall also be designed to retain grease until accumulations can be removed by pumping the interceptor. It is recommended that a sample box be located at the outlet end of all grease interceptors so that the administrative authority can periodically sample effluent quality.
