RESOLUTION APPROVING APPLICATION OF THE FATS, OILS, AND GREASE
(FOG)PERCENTAGE CALCULATIONS
FOR THE CITY OF AMES
WHEREAS, the City's adopted FOG Control Program includes a requirement for Food
Service Establishments (FSE's) to demonstrate their compliance with the program every six months;
and,
WHEREAS, one of the ways they can demonstrate compliance is by cleaning their grease
interceptors frequently enough that, on average, their interceptor is "...25% or less..." filled with
floating grease or settled solids prior to each cleaning; and,
WHEREAS, in the recent compliance period, a FSE cleaned their interceptor seven times;
and,
WHEREAS, the volume of solids and volume of grease each measured to the nearest inch,
and the average of their seven cleanings was 25.3%; and,
WHEREAS, it is staffs interpretation that the precision of the readings, having been taken
to the nearest inch, are not precise enough to warrant calculating the average value to three
significant figures (XX.X%); and,
WHEREAS, staff intends to establish an administrative practice whereby the calculated
average is rounded to only two significant figures (XX%) using the common statistical convention
of rounding values of 25.49% or less down to 25% and rounding values of 25.50% or greater up to
26%; and,
WHEREAS, in the situation at hand, the calculated average of 25.3% would be rounded
down to 25%, and the FSE would be deemed to be in compliance with the program (and, thus, not
subject to the FOG surcharge for the next six months); and,
WHEREAS, since this is the first time this situation has occurred under the relatively new
FOG Control Program, staff would like to confirm the City Council's support for this approach.
NOW, THEREFORE, BE IT RESOLVED by the City Council of the City of Ames, Iowa,
that concurrence with staffs approach of rounding the calculated average value up or down to two
significant figures using common statistical rounding conventions for the application of Fats, Oils,
and Grease linut is hereby approved.
