Section 33-24-05-402 - Standards - Process vents1. The owner or operator of a facility with process vents associated with distillation, fractionation, thin-film evaporation, solvent extraction, or air or steam stripping operations managing hazardous wastes with organic concentrations of at least ten parts per million weight shall either: a. Reduce total organic emissions from all affected process vents at the facility below one and four-tenths kilograms/hour (three pounds per hour and two and eight-tenths megagrams/year (three and one-tenth tons/year); or b. Reduce, by use of a control device, total organic emissions from all affected process vents at the facility by ninety-five weight percent. 2. If the owner or operator installs a closed-vent system and control device to comply with the provisions of subsection 1, the closed-vent system and control device must meet the requirements of section 33-24-05-403. 3. Determinations of vent emissions and emission reductions or total organic compound concentrations achieved by add-on control devices may be based on engineering calculations or performance tests. If performance tests are used to determine vent emissions, emission reductions, or total organic compound concentrations achieved by add-on control devices, the performance tests must conform with the requirements of subsection 3 of section 33-24-05-404. 4. When an owner or operator and the department do not agree on determinations of vent emissions or emission reductions, or both, or total organic compound concentrations achieved by add-on control devices based on engineering calculations, the procedures in subsection 3 of section 33-24-05-404 must be used to resolve the disagreement.
