Standards - Process vents

1. The remanufacturer or other person that stores or treats hazardous secondary materials in hazardous secondary material management units with process vents associated with distillation, fractionation, thin-film evaporation, solvent extraction, or air or steam stripping operations managing hazardous secondary material with organic concentrations of at least ten parts per million weight either shall: a. Reduce total organic emissions from all affected process vents at the facility below one and four-tenths kilograms per hour (three pounds per hour) and two and eight-tenths megagrams per year (three and one-tenth tons per 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 remanufacturer or other person that stores or treats the hazardous secondary material 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 33.1-24-02-173. 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 33.1-24-02-174. 4. When a remanufacturer or other person that stores or treats the hazardous secondary material 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 33.1-24-02-174 must be used to resolve the disagreement.
