Utah Admin. Code 315-265-252
In addition to the waste analyses required by Section R315-265-13, the owner or operator shall analyze a representative sample of waste from each incoming movement before adding the waste to any existing pile, unless (1) The only wastes the facility receives which are amenable to piling are compatible with each other, or (2) the waste received is compatible with the waste in the pile to which it is to be added. The analysis conducted shall be capable of differentiating between the types of hazardous waste the owner or operator places in piles, so that mixing of incompatible waste does not inadvertently occur. The analysis shall include a visual comparison of color and texture.
Comment: As required by Section R315-265-13, the waste analysis plan shall include analyses needed to comply with Sections R315-265-256 and 265-257. As required by Section R315-265-73, the owner or operator shall place the results of this analysis in the operating record of the facility.
