# §279.55. 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](/cfr/40/279.53.md) and, if applicable, [§ 279.72](/cfr/40/279.72.md). 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](/cfr/40/part261.md) of this chapter; or
      - (B) A method shown to be equivalent under §§ [260.20](/cfr/40/260.20.md) and [260.21](/cfr/40/260.21.md) 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](/cfr/40/279.53.md); 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](/cfr/40/279.72.md) 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](/cfr/40/part261.md) of this chapter; or
      - (B) A method shown to be equivalent under §§ [260.20](/cfr/40/260.20.md) and [260.21](/cfr/40/260.21.md) 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](/cfr/40/279.72.md); and
  - (3) The type of information that will be used to make the on-specification used oil fuel determination.
