Maintenance and cleaning events must be recorded in written form and kept on file on site. The records shall be made available to LFUCG Division of Water Quality inspectors upon request. %%EOF The grease interceptor (GI) must be constructed in accordance with the current plumbing codes adopted by the City of Austin, as amended, and installed in a manner acceptable to the Development Services Division (no exceptions); The GI shall have two compartments.
Every business or establishment that produces and disposes of fat, oil or grease (FOGs), such as restaurants, food processing establishments, hospitals, and day care and senior centers, must have a grease interceptor system to prevent the discharge of waste grease into the City's sewer systems. Factors such as types of food, cooking methods, cleaning techniques, carry-out verses dine-in, all will determine volume of grease discharged. For engineered GGIs, specific models shall meet the following requirements: The goal for engineered GGIs is to closely comply to the concrete GGI requirements but allow slight flexibility if site conditions are not ideal for a concrete GGI. Austin Waters Office of Industrial Waste (IW) modified its grease interceptor policies in April 2021.
You may need additional information to meet the legal requirements for starting or operating your business. After approval, the facility will be issued a grease interceptor permit and the grease interceptor can be installed. Leaving accumulated solids in the bottom of grease interceptors can lead to short circuiting and reduced retention times, as well as, very unpleasant odors. 0000001087 00000 n 0000001832 00000 n
The approved design for GGIs shall be as follows: Exceptions to the above criteria may be considered for approval in conjunction with the Building Plan Review process. Maintenance of external large capacity grease interceptors should be performed by qualified grease or septic haulers. 0000000731 00000 n Must comply with American Society of Civil Engineers (ASME) A112.14.3 standard; Must be flow-rated at 75-gallons per minute (GPM) or higher; Must be constructed of non-corrodiblematerials; Must be installed per ASME A112.14.3 Type D standard (indirect connection without external flow control); Must have a minimum liquid capacity consistent with the IW approval letter specified minimum; and.
Facilities with high grease loadings may have to clean their interceptors as often as monthly. 0000006050 00000 n Examples of such features would include a flow diverter plate in the primary compartment, "tee" piping between the two GI compartments and "tee" piping on the tank outlet; Be constructed of concrete or non-corrodible materials; Each GI compartment shall be accessible for cleaning and inspection purposes (no exceptions).
0000002178 00000 n Extremely large volume GIs may have three compartments; While operating at the GI's rated flow capacity, the first compartment must provide a retention time of no less than seven minutes, and the second compartment must provide a retention time of no less than five minutes (~60/40 split); GI inverts and vents shall be external to the compartments.
The GI flowline (upstream of inlet invert) must be at least 3 inches above the tanks static water level; The GI vent must be at least 3 inches above the static water level of the tank; The GI inlet must be near an elevation that is one half of the tank's static water level height, and the GI outlet must be at least 12 inches above the tank floor; Adequate flow diffusion features must be provided to evenly distribute flow throughout the GI. 0 Shall include a60/40 split between compartments to allow for adequate retention time, similar to a GGI; Shall beconstructed of non-corrodible materials; May have either internal or external inverts. The interceptor shall contain a baffle system, which adequately diverts and slows the flow to avoid short-circuiting. City of New York. A copy of the FOG Permit issued by the Division ofWater Qualityshall be kept on file at the facility the permit has been issued to. Managers signature or initials for verification.

HGIs greater than 500 gallons must have a 60/40 split between compartments. To properly clean a grease interceptor, the entire contents (liquids and solids) must be pumped out. A list of localseptic/grease haulersis available on our website. As per LFUCG ordinance requirements, grease interceptors shall be constructed of impervious materials capable of withstanding abrupt and extreme changes in temperatures, shall be of substantial construction, watertight and equipped with easily removable covers.
