Chapter NR 664 - Hazardous Waste Treatment, Storage And Disposal Facility Standards
Subchapter CC - Air Emission Standards for Tanks, Surface Impoundments and Containers
Section NR 664.1082 - Standards: general

1. A process that removes or destroys the organics contained in the hazardous waste to a level such that the average VO concentration of the hazardous waste at the point of waste treatment is less than the exit concentration limit (Ct) established for the process. Determine the average VO concentration of the hazardous waste at the point of waste treatment and the exit concentration limit for the process using the procedures in s. NR 664.1083(2).

2. A process that removes or destroys the organics contained in the hazardous waste to a level such that the organic reduction efficiency (R) for the process is equal to or greater than 95%, and the average VO concentration of the hazardous waste at the point of waste treatment is less than 100 ppmw. Determine the organic reduction efficiency for the process and the average VO concentration of the hazardous waste at the point of waste treatment using the procedures in s. NR 664.1083(2).

3. A process that removes or destroys the organics contained in the hazardous waste to a level such that the actual organic mass removal rate (MR) for the process is equal to or greater than the required organic mass removal rate (RMR) established for the process. Determine the required organic mass removal rate and the actual organic mass removal rate for the process using the procedures in s. NR 664.1083(2).

4. A biological process that destroys or degrades the organics contained in the hazardous waste, such that any of the following conditions is met:

5. A process that removes or destroys the organics contained in the hazardous waste and meets all of the following conditions:

6. A process that removes or destroys the organics contained in the hazardous waste to a level such that the organic reduction efficiency (R) for the process is equal to or greater than 95% and the owner or operator certifies that the average VO concentration at the point of waste origination for each of the individual waste streams entering the process is less than 10,000 ppmw. Determine the organic reduction efficiency for the process and the average VO concentration of the hazardous waste at the point of waste origination using the procedures in s. NR 664.1083(2) and (1), respectively.

7. A hazardous waste incinerator for which any of the following conditions has been met:

8. A boiler or industrial furnace for which any of the following conditions has been met:

9. For the purpose of determining the performance of an organic destruction or removal process according to subds. 1. to 6., the owner or operator shall account for VO concentrations determined to be below the limit of detection of the analytical method using the following VO concentration:

1. The waste meets the numerical concentration limits for organic hazardous constituents, applicable to the hazardous waste, as specified in ch. NR 668- Hazardous Waste Land Disposal Restrictions under Table "Treatment Standards for Hazardous Waste" in s. NR 668.40.

2. The organic hazardous constituents in the waste have been treated by the treatment technology established by the department for the waste in s. NR 668.42(1), or have been removed or destroyed by an equivalent method of treatment approved by EPA pursuant to 40 CFR 268.42(b).

1. The tank is located inside an enclosure vented to a control device that is designed and operated according to all applicable requirements in 40 CFR part 61, subpart FF-National Emission Standards for Benzene Waste Operations, for a facility at which the total annual benzene quantity from the facility waste is equal to or greater than 10 megagrams per year.

2. The enclosure and control device serving the tank were installed and began operation prior to June 1, 1998.

3. The enclosure is designed and operated according to the criteria for a permanent total enclosure in Method 204- "Criteria for and Verification of a Permanent or Temporary Total Enclosure" of appendix M of 40 CFR part 51, incorporated by reference in s. NR 660.11. The enclosure may have permanent or temporary openings to allow worker access, passage of material into or out of the enclosure by conveyor, vehicles or other mechanical or electrical equipment or to direct air flow into the enclosure. Perform the verification procedure for the enclosure in Section 8 of Method 204 annually.

1. According to the method used by the owner or operator to perform the waste analysis, except in the case specified in subd. 2.

2. If the department determines that the method used by the owner or operator was not appropriate for the hazardous waste managed in the tank, surface impoundment or container, then the department may choose an appropriate method.

1. Determine the average VO concentration of the hazardous waste at the point of waste origination by direct measurement according to s. NR 664.1083(1).

2. Results of the waste determination performed or requested by the department showing that the average VO concentration of the hazardous waste at the point of waste origination is equal to or greater than 500 ppmw shall constitute noncompliance with this subchapter except in a case provided for in subd. 3.

3. For the case when the average VO concentration of the hazardous waste at the point of waste origination previously has been determined by the owner or operator using an averaging period greater than one hour to be less than 500 ppmw but because of normal operating process variations the VO concentration of the hazardous waste determined by direct measurement for any given one-hour period may be equal to or greater than 500 ppmw, the department shall consider information that was used by the owner or operator to determine the average VO concentration of the hazardous waste (e.g., test results, measurements, calculations and other documentation) and recorded in the facility records according to ss. NR 664.1083(1) and 664.1089 together with the results of the waste determination performed or requested by the department in establishing compliance with this subchapter.
