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.(c) In a case when the owner or operator is requested to perform the waste determination, the department may elect to have an authorized representative observe the collection of the hazardous waste samples used for the analysis.(d) In a case when the results of the waste determination performed or requested by the department do not agree with the results of a waste determination performed by the owner or operator using knowledge of the waste, the department may use the results of the waste determination performed according to par. (a) to establish compliance with this subchapter. (e) In a case when the owner or operator has used an averaging period greater than one hour for determining the average VO concentration of a hazardous waste at the point of waste origination, the department may elect to establish compliance with this subchapter by performing, or requesting that the owner or operator perform, a waste determination using direct measurement based on waste samples collected within a one-hour period as follows: 1. Determine the average VO concentration of the hazardous waste at the point of waste origination by direct measurement according to s. NR 665.1084(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 665.1084(1) and 665.1090 to gether with the results of the waste determination performed or requested by the department in establishing compliance with this subchapter.Wis. Admin.
