Utah Admin. Code R315-262-11 - General - Hazardous Waste Determination and Recordkeeping

A person who generates a solid waste, as defined in Section R315-261-2, shall make an accurate determination as to whether that waste is a hazardous waste in order to ensure wastes are properly managed according to applicable regulations. A hazardous waste determination is made using the following steps:

(a) The hazardous waste determination for each solid waste shall be made at the point of waste generation, before any dilution, mixing, or other alteration of the waste occurs, and at any time in the course of its management that it has, or may have, changed its properties as a result of exposure to the environment or other factors that may change the properties of the waste such that the hazardous classification of the waste may change.
(b) A person shall determine whether the solid waste is excluded from regulation under Section R315-261-4.
(c) If the waste is not excluded under Section R315-261-4, the person shall then use knowledge of the waste to determine whether the waste meets any of the listing descriptions under Sections R315-261-30 through R315-261-35. Acceptable knowledge that may be used in making an accurate determination as to whether the waste is listed may include waste origin, composition, the process producing the waste, feedstock, and other reliable and relevant information. If the waste is listed, the person may file a delisting petition under Sections R315-260-20 and R315-260-22 to demonstrate to the Director that the waste from this particular site or operation is not a hazardous waste.
(d) The person then shall also determine whether the waste exhibits one or more hazardous characteristics as identified in Sections R315-261-20 through R315-261-24 by following the procedures in Subsections R315-262-11(d)(1) or (2), or a combination of both.
(1) The person shall apply knowledge of the hazard characteristic of the waste in light of the materials or the processes used to generate the waste. Acceptable knowledge may include process knowledge, for example, information about chemical feedstocks and other inputs to the production process; knowledge of products, by-products, and intermediates produced by the manufacturing process; chemical or physical characterization of wastes; information on the chemical and physical properties of the chemicals used or produced by the process or otherwise contained in the waste; testing that illustrates the properties of the waste; or other reliable and relevant information about the properties of the waste or its constituents. A test other than a test method set forth in Sections R315-261-20 through R315-261-24, or an equivalent test method approved by the Director under Section R315-260-21, may be used as part of a person's knowledge to determine whether a solid waste exhibits a characteristic of hazardous waste. However, such tests do not, by themselves, provide definitive results. Persons testing their waste shall obtain a representative sample of the waste for the testing, as defined at Section R315-260-10.
(2) When available knowledge is inadequate to make an accurate determination, the person shall test the waste according to the applicable methods set forth in Sections R315-261-20 through R315-261-24 or according to an equivalent method approved by the Director under Section R315-260-21 and in accordance with the following:
(i) Persons testing their waste shall obtain a representative sample of the waste for the testing, as defined at Section R315-260-10.
(ii) Where a test method is specified in Sections R315-261-20 through R315-261-24, the results of the regulatory test, when properly performed, are definitive for determining the regulatory status of the waste.
(e) If the waste is determined to be hazardous, the generator shall refer to Rules R315-261, R315-264, R315-265, R315-266, R315-268, and R315-273 for other possible exclusions or restrictions pertaining to management of the specific waste.
(f) Recordkeeping for small and large quantity generators. A small or large quantity generator shall maintain records supporting its hazardous waste determinations, including records that identify whether a solid waste is a hazardous waste, as defined by Section R315-261-3. Records shall be maintained for at least three years from the date that the waste was last sent to on-site or off-site treatment, storage, or disposal. These records shall comprise the generator's knowledge of the waste and support the generator's determination, as described at Subsections R315-262-11(c) and (d). The records shall include, but are not limited to, the following types of information: The results of any tests, sampling, waste analyses, or other determinations made in accordance with this section; records documenting the tests, sampling, and analytical methods used to demonstrate the validity and relevance of such tests; records consulted in order to determine the process by which the waste was generated, the composition of the waste, and the properties of the waste; and records which explain the knowledge basis for the generator's determination, as described at Subsection R315-262-11(d)(1). The periods of record retention referred to in Subsection R315-262-11(2)(f) are extended automatically during the course of any unresolved enforcement action regarding the regulated activity or as requested by the Director.
(g) Identifying hazardous waste numbers for small and large quantity generators. If the waste is determined to be hazardous, small quantity generators and large quantity generators shall identify all applicable EPA hazardous waste numbers, EPA hazardous waste codes, in Sections R315-261-20 through R315-261-24 and R315-261-30 through R315-261-35. Prior to shipping the waste off site, the generator also shall mark its containers with all applicable EPA hazardous waste numbers, EPA hazardous waste codes, according to Section R315-262-32.
