Analysis plan.

Owners or operators of used oil processing and re-refining facilities must develop and follow a written analysis plan describing the procedures that will be used to comply with the analysis requirements of § 279.53 and, if applicable, § 279.72. The owner or operator must keep the plan at the facility. (a) Rebuttable presumption for used oil in § 279.53. At a minimum, the plan must specify the following: (1) Whether sample analyses or knowledge of the halogen content of the used oil will be used to make this determination. (2) If sample analyses are used to make this determination: (i) The sampling method used to obtain representative samples to be analyzed. A representative sample may be obtained using either: (A) One of the sampling methods in appendix I of part 261 of this chapter; or (B) A method shown to be equivalent under §§ 260.20 and 260.21 of this chapter; (ii) The frequency of sampling to be performed, and whether the analysis will be performed on-site or off-site; and (iii) The methods used to analyze used oil for the parameters specified in § 279.53; and (3) The type of information that will be used to determine the halogen content of the used oil. (b) On-specification used oil fuel in § 279.72. At a minimum, the plan must specify the following if § 279.72 is applicable: (1) Whether sample analyses or other information will be used to make this determination; (2) If sample analyses are used to make this determination: (i) The sampling method used to obtain representative samples to be analyzed. A representative sample may be obtained using either: (A) One of the sampling methods in appendix I of part 261 of this chapter; or (B) A method shown to be equivalent under §§ 260.20 and 260.21 of this chapter; (ii) Whether used oil will be sampled and analyzed prior to or after any processing/re-refining; (iii) The frequency of sampling to be performed, and whether the analysis will be performed on-site or off-site; and (iv) The methods used to analyze used oil for the parameters specified in § 279.72; and (3) The type of information that will be used to make the on-specification used oil fuel determination.
