Section 373-3.17 - Chemical, physical and biological treatment

(a) The regulations in this section apply to owners and operators of facilities subject to this Subpart which treat hazardous waste by chemical, physical or biological methods in other than tanks, surface impoundments and land treatment facilities. Chemical, physical and biological treatment of hazardous waste in tanks, surface impoundments and land treatment facilities must be conducted in accordance with sections 373-3.10, 373-3.11 and 373-3.13 of this Subpart.

(b)General operating requirements.

(1) Chemical, physical or biological treatment of hazardous waste must comply with section 373-3.2(h) of this Subpart.

(2) Hazardous wastes or treatment reagents must not be placed in the treatment process or equipment if they could cause the treatment process or equipment to rupture, leak, corrode or otherwise fail before the end of its intended life.

(3) Where hazardous waste is continuously fed into a treatment process or equipment, the process or equipment must be equipped with a means to stop this inflow (e.g., a waste feed cutoff system or bypass system to a standby containment device).

(c)Waste analysis and trial tests.

(1) In addition to the waste analysis required by section 373-3.2(d) of this Subpart, whenever:

(i) a hazardous waste which is substantially different from waste previously treated in a treatment process or equipment at the facility is to be treated in that process or equipment; or

(ii) a substantially different process than any previously used at the facility is to be used to chemically treat hazardous waste: the owner or operator must, before treating the different waste or using the different process or equipment:

(a) conduct waste analysis and trial treatment tests (e.g., bench scale or pilot plant scale tests); or

(b) obtain written, documented information on similar treatment of similar waste under similar operating conditions; to show that this proposed treatment will meet all applicable requirements of paragraphs (b)(1) and (2) of this section.

(d)Inspections.

(1) The owner or operator of a treatment facility must inspect, where present:

(i) discharge control and safety equipment (e.g., waste feed cutoff systems, bypass systems, drainage systems and pressure relief systems), at least once each operating day, to ensure that it is in good working order;

(ii) data gathered from monitoring equipment (e.g., pressure and temperature gauges), at least once each operating day, to ensure that the treatment process or equipment is being operated according to its design;

(iii) the construction materials of the treatment process or equipment, at least weekly, to detect corrosion or leaking of fixtures or seams; and

(iv) the construction materials of, and the area immediately surrounding, discharge confinement structures (e.g., dikes), at least weekly, to detect erosion or obvious signs of leakage (e.g., wet spots or dead vegetation).

(e)Closure.

At closure, all hazardous waste and hazardous waste residues must be removed from treatment processes or equipment, discharge control equipment and discharge confinement structures.

(f)Special requirements for ignitable or reactive wastes.

(1) Ignitable or reactive waste must not be placed in a treatment process or equipment unless:

(i) the waste is treated, rendered or mixed before or immediately after placement in the treatment process or equipment so that:

(a) the resulting waste mixture, or dissolution of material, no longer meets the definition of ignitable or reactive waste under section 371.3(b) or (d) of this Title; and

(b) section 373-3.2(h) of this Subpart is complied with; or

(ii) the waste is treated in such a way that it is protected from any material or conditions which may cause the waste to ignite or react.

(g)Special requirements for incompatible wastes.

(1) Incompatible wastes, or incompatible wastes and materials (see Appendix 29, infra, for examples), must not be placed in the same treatment process or equipment unless section 373-3.2(h) of this Subpart is complied with.

(2) Hazardous waste must not be placed in unwashed treatment equipment which previously held an incompatible waste or material, unless section 373-3.2(h) of this Subpart is complied with.
