(iii) Recyclable materials from which precious metals are reclaimed (40 CFR part 266, subpart F);

(iv) Spent lead acid batteries that are being reclaimed (40 CFR part 266, subpart G).

(3) The following recyclable materials are not subject to regulation under and are not subject to the notification requirements of section 3010 of RCRA:

(i) Industrial ethyl alcohol that is reclaimed except that exports and imports of such recyclable materials [shall] comply with the requirements of 40 CFR part 262, sub-part H.

(A) A person initiating a shipment for reclamation in a foreign country, and any intermediary arranging for the shipment, [shall] comply with the requirements applicable to a primary exporter in [§ 262. 83(b), (g) and (i),] export such materials only upon consent of the receiving country and in conformance with the EPA Acknowledgment of Consent as defined in [subpart H] of part 262, and provide a copy of the EPA Acknowledgment of Consent to the shipment to the transporter transporting the shipment for export;

(B) Transporters transporting a shipment for export may not accept a shipment if [the transporter] knows the shipment does not conform to the EPA Acknowledgment of Consent, [shall] ensure that a copy of the EPA Acknowledgment of Consent accompanies the shipment and [shall] ensure that [the EPA Acknowledgment of Consent] is delivered to the [subsequent transporter or] facility designated by the person initiating the shipment.

(ii) Scrap metal that is not excluded under § 261. 4(a)(13);

(iii) Fuels produced from the refining of oil-bearing hazardous waste along with normal process streams at a petroleum refining facility if such wastes result from normal petroleum refining, production, and transportation practices (this exemption does not apply to fuels produced from oil recovered from oil-bearing hazardous waste, where such recovered oil is already excluded under § 261. 4(a)(12);

(iv)

(A) Hazardous waste fuel produced from oil-bearing hazardous wastes from petroleum refining, production, or transportation practices, or produced from oil reclaimed from such hazardous wastes, where such hazardous wastes are reintroduced into a process that does not use distillation or does not produce products from crude oil so long as the resulting fuel meets the used oil specification under [A. R. S. § 49-801] and so long as no other hazardous wastes are used to produce the hazardous waste fuel;

(B) Hazardous waste fuel produced from oil-bearing hazardous waste from petroleum refining[,] production, and transportation practices, where such hazardous wastes are reintroduced into a refining process after a point at which contaminants are removed, so long as the fuel meets the used oil fuel specification under [A. R. S. § 49-801] ; and

(C) Oil reclaimed from oil-bearing hazardous wastes from petroleum refining, production, and transportation practices, which reclaimed oil is burned as a fuel without reintroduction to a refining process, so long as the reclaimed oil meets the used oil fuel specification under [A.

G. § 261. 11, titled "Criteria for listing hazardous waste," paragraph (a) is amended as follows:

(a) The [Director] shall list a solid waste as a hazardous waste only upon determining that the solid waste meets one of the following criteria:

(1) It exhibits any of the characteristics of hazardous waste identified in subpart C.

(2) It has been found to be fatal to humans in low doses or, in the absence of data on human toxicity, it has been shown in studies to have an oral LD 50 toxicity (rat) of less than 50 milligrams per kilogram, an inhalation LC 50 toxicity (rat) of less than 2 milligrams per liter, or a dermal LD 50 toxicity (rabbit) of less than 200 milligrams per kilogram or is otherwise capable of causing or significantly contributing to an increase in serious irreversible, or incapacitating reversible, illness. (Waste listed in accordance with these criteria shall be designated Acute Hazardous Waste.)

(3) It contains any of the toxic constituents listed in Appendix VIII and, after considering the following factors, the [Director] concludes that the waste is capable of posing a substantial present or potential hazard to human health or the environment when improperly treated, stored, transported, or disposed of, or otherwise managed:

(i) The nature of the toxicity presented by the constituent.

(ii) The concentration of the constituent in the waste.

(iii) The potential of the constituent or any toxic degradation product of the constituent to migrate from the waste into the environment under the types of improper management considered in (a)(3)(vii) of this [subsection].

(iv) The persistence of the constituent or any toxic degradation product of the constituent.

(v) The potential for the constituent or any toxic degradation product of the constituent to degrade into nonharmful constituents and the rate of degradation.

(vi) The degree to which the constituent or any degradation product of the constituent bioaccumulates in ecosystems.

(vii) The plausible types of improper management to which the waste could be subjected.

(viii) The quantities of the waste generated at individual generation sites or on a regional or national basis.

(ix) The nature and severity of the human health and environmental damage that has occurred as a result of the improper management of wastes containing the constituent.

(x) Action taken by other governmental agencies or regulatory programs based on the health or environmental hazard posed by the waste or waste constituent.

(xi) Such other factors as may be appropriate.

H. § 261. 11, titled "Criteria for listing hazardous waste," paragraph (c) is amended as follows:

(c) The Administrator will use the criteria for listing specified in this section to establish the exclusion limits referred to in [262. 13(c).]

I. § 261. 30, titled "General", paragraph (d) is amended as follows:

(d) The following hazardous wastes listed in § 261. 31 are subject to the exclusion limits for acutely hazardous wastes established in [§ 261. 13:] EPA Hazardous Wastes Nos. F020, F021, F022, F023, F026 and F027.
