Description of technology-based standards

AMLGM

Amalgamation of liquid, elemental mercury contaminated with radioactive materials utilizing inorganic reagents such as copper, zinc, nickel, gold, and sulfur that result in a nonliquid, semi-solid amalgam and thereby reducing potential emissions of elemental mercury vapors to the air.

BIODG

Biodegradation of organics or non-metallic inorganics (i.e., degradable inorganics that contain the elements of phosphorus, nitrogen, and sulfur) in units operated under either aerobic or anaerobic conditions such that a surrogate compound or indicator parameter has been substantially reduced in concentration in the residuals (e.g., total organic carbon can often be used as an indicator parameter for the biodegradation of many organic constituents that cannot be directly analyzed in wastewater residues).

CARBN

Carbon adsorption (granulated or powdered) of non-metallic inorganics, organo-metallics, or organic constituents, operated such that a surrogate compound or indicator parameter has not undergone breakthrough (e.g., total organic carbon can often be used as an indicator parameter for the adsorption of many organic constituents that cannot be directly analyzed in wastewater residues). Breakthrough occurs when the carbon has become saturated with the constituent (or indicator parameter) and substantial change in adsorption rate associated with that constituent occurs.

2 When more than one technology (or treatment train) is specified as alternative treatment standards, the five letter technology codes (or the treatment trains) are separated by a semicolon with the last technology preceded by the word "or". This indicates that any one of these best demonstrated available technologies (BDATs) or treatment trains can be used for compliance with the standard.

(B) Any person may submit an application to the director demonstrating that an alternative treatment method can achieve a measure of performance equivalent to that achieved by methods specified in paragraphs (A), (C), and (D) of this rule for wastes or specified in the table in rule 3745-270-45 of the Administrative Code for hazardous debris. The applicant shall submit information demonstrating that the applicant's treatment method is in compliance with federal, state, and local requirements and is protective of human health and the environment. On the basis of such information and any other available information, the administrator may approve the use of the alternative treatment method if the director finds that the alternative treatment method provides a measure of performance equivalent to that achieved by methods specified in paragraphs (A), (C), and (D) of this rule for wastes or in the table in rule 3745-270-45 of the Administrative Code for hazardous debris. Any approval shall be stated in writing and may contain such provisions and conditions as the director deems appropriate. The person to whom such approval is issued shall comply with all limitations contained in such a determination.

(C) As an alternative to the otherwise applicable treatment standards in rules 3745-270-40 to 3745-270-49 of the Administrative Code, lab packs are eligible for land disposal provided the all of following requirements are met:

(1) The lab packs comply with the applicable provisions of rules 3745-57-16 and 3745-68-16 of the Administrative Code.

(2) The lab pack does not contain any of the wastes listed in appendix A to this rule.

(3) The lab packs are incinerated in accordance with rules 3745-57-40 to 3745-57-51 or 3745-68-40 to 3745-68-52 of the Administrative Code.

(4) Any incinerator residues from lab packs containing D004, D005, D006, D007, D008, D010, and D011 are treated in compliance with the applicable treatment standards specified for such wastes in rules 3745-270-40 to 3745-270-49 of the Administrative Code.

(D) Radioactive hazardous mixed wastes are subject to the treatment standards in rule 3745-270-40 of the Administrative Code. Where treatment standards are specified for radioactive mixed wastes in the table of treatment standards, those treatment standards will govern. Where there is no specific treatment standard for radioactive mixed waste, the treatment standard for the hazardous waste (as designated by EPA hazardous waste number) applies. Hazardous debris containing radioactive waste is subject to the treatment standards specified in rule 3745-270-45 of the Administrative Code.
