(a) remove FOG from effluent
(b) retain separated FOG
(c) internally dispose retained FOG by means and methods of mass and volume reduction as required by para. 4,3.2
The use of alternate materials or methods are permitted, provided the proposed material and method complies with the performance requirements and intent of this Standard.
1.2 Units of Measurement
Where values are stated in U.S. Customary units and the International System of Units (SI), the U.S. Customary units shall be considered as the standard.
In this Standard, gallons (U.S. liquid) per minute is abbreviated gpm and liters (metric Liquid) per minute is abbreviated L/min.
1.3 ReFerences

ASTM A 888, Standard Specification for Hubless Cast Iron Soil Pipe and Fittings for Sanitary and Storm
(a) Measure the total liquid volume of the system at the point of discharge.
(b) Calculate the test flow rate (in gpm) by dividing the nameplate flow rate (in gpm) by 4.
(c) Install the system in accordance with the manufacturer’s instructions.
(d) Connect the inlet of the system to a potable water supply capable of providing the test flow rate at a temperature between 70°F and 76°F. Charge the system at the test flow rate, with FOG having a specific gravity of 0,875 ± 0.005, at 150F being injected into the influent at the rate of 300 mg/I. Activate the disposal function and allow it to stabilize in accordance with the manufacturer’s instructions.
4.3.2 Acceptance Criteria. Once the system is stabilized (when the functions of separation, retention, and disposal are fully operational in accordance with the manufacturer’s requirements), sample (a representative portion of system discharge consisting of four discrete quantities of a least I L each) the final effluent and determine the quantity of FOG in accordance with USEPA Method 1664. The final effluent from FOG internal disposal systems shall contain no more than 100 mg/L FOG as measured by USEPA Method 1664.
5 MARKING
5.1 Marking and Identification
FOG disposal systems shall be permanently and legibly marked with the following:
(a) manufacturer’s name and/or trademark
(b) model number
(C) rated flow (in gpm) and metric equivalent
(d) “inlet” and “outlet”
(e) third party certification marking as required
(f) ASME A112.14.6.
