NR 440.70(15)(j)9.9. Each owner or operator of an affected facility that uses a catalytic incinerator shall maintain continuous records of the temperature of the gas stream both upstream and downstream of the catalyst bed of the incinerator, records of all 3-hour periods of operation during which the average temperature measured before the catalyst bed is more than 28°C (50°F) below the design gas stream temperature and records of all 3-hour periods during which the average temperature difference across the catalyst bed is less than 80% of the design temperature difference and shall keep such records for 2 years after the information is recorded.

NR 440.70(15)(j)10.10. Each owner or operator of an affected facility that uses a carbon absorber shall maintain continuous records of the VOC concentration level or reading of organics of the control device outlet gas stream or inlet and outlet gas stream and records of all 3-hour periods of operation during which the average VOC concentration level or reading of organics in the exhaust gases or inlet and outlet gas stream, is more than 20% greater than the design exhaust gas concentration level and shall keep such records for 2 years after the information is recorded.

NR 440.70(15)(j)11.11. Each owner or operator that uses a carbon adsorber which is regenerated directly onsite shall maintain continuous records of the VOC concentration level or reading of organics of the control device outlet gas stream or inlet and outlet gas stream and records of all 3-hour periods of operation during which the average VOC concentration level or reading of organics in the exhaust gases or inlet and outlet gas stream, is more than 20% greater than the design exhaust gas concentration level and shall keep such records for 2 years after the information is recorded.

NR 440.70(15)(j)12.12. Each owner or operator that uses a carbon adsorber that is not regenerated directly onsite in the control device shall maintain records of dates and times when the control device is monitored, when breakthrough is measured, and shall record the date and time that the existing carbon in the control device is replaced with fresh carbon.

NR 440.70(15)(k)(k) If an owner or operator elects to install a tightly sealed cap or plug over a drain that is out of active service, the owner or operator shall keep for the life of a facility in a readily accessible location, plans or specifications which indicate the location of such drains.

NR 440.70(15)(L)(L) For stormwater sewer systems subject to the exclusion in sub. (3) (d), an owner or operator shall keep for the life of the facility in a readily accessible location, plans or specifications which demonstrate that no wastewater from any process units or equipment is directly discharged to the stormwater sewer system.

(3) (e), an owner or operator shall keep for the life of a facility in a readily accessible location, plans or specifications which demonstrate that the ancillary equipment does not come in contact with or store oily wastewater.

NR 440.70(15)(n)(n) For non-contact cooling water system subject to the exclusion in sub. (3) (f) an owner or operator shall keep for the life of the facility in a readily accessible location, plans or specifications which demonstrate that the cooling water does not contact hydrocarbons or oily wastewater and is not recirculated through a cooling tower.
