NR 439.04(6)(b)2.c.c. For a carbon adsorption system that employs monitoring and recording equipment to measure and record the total mass steam flow rate for each regeneration cycle of each carbon bed, all carbon bed regeneration cycles during which the total mass steam flow rate was more than 10% below the total mass steam flow rate during the most recent performance test that demonstrated that the solvent cleaning operation was in compliance.

NR 439.05(1)(1) No person may deny information or access to records relating to emissions or any other records required to be kept to an authorized representative of the department. NR 439.05(2)(2) No person may deny entry or access at any reasonable time to an authorized representative of the department for the purposes of inspection of facilities, equipment, including monitoring and air pollution control equipment, practices or operations regulated or required by the department, or at any time when an air pollution episode condition exists or is believed imminent. No person may obstruct, hamper or interfere with any inspection. The department, if requested, shall furnish to the owner or operator of the premises a report setting forth all facts found which relate to compliance status. NR 439.05(3)(3) The department may, for the purpose of determining a source’s compliance with applicable requirements, sample or monitor at reasonable times production materials or other substances or operational parameters.
