NR 465.38(9)(g)1.f. f. Perform leak checks monthly.

NR 465.38(9)(g)1.g. g. Perform visual inspections of the sensor system quarterly if there is no redundant sensor.

NR 465.38(9)(g)2. 2. For each pressure drop measurement device, you shall comply with the requirements in par. (a) and subd. 2. a. to g.

NR 465.38(9)(g)2.a. a. Locate the pressure sensor in or close to a position that provides a representative measurement of the pressure drop across each opening you are monitoring.

NR 465.38(9)(g)2.b. b. Use a pressure sensor with an accuracy of at least 0.5 inches of water column or 5% of the measured value, whichever is larger.

NR 465.38(9)(g)2.c. c. Perform an initial calibration of the sensor according to the manufacturer’s requirements.

NR 465.38(9)(g)2.d. d. Conduct a validation check before initial operation or upon relocation or replacement of a sensor. Validation checks include comparison of sensor values to calibrated pressure measurement devices or to pressure simulation using calibrated pressure sources.

NR 465.38(9)(g)2.e. e. Conduct accuracy audits every quarter and after every deviation. Accuracy audits include comparison of sensor values to calibrated pressure measurement devices or to pressure simulation using calibrated pressure sources.

NR 465.38(9)(g)2.f. f. Perform monthly leak checks on pressure connections. A pressure of at least 1.0 inches of water column to the connection shall yield a stable sensor result for at least 15 seconds.

NR 465.38(9)(g)2.g. g. Perform a visual inspection of the sensor at least monthly if there is no redundant sensor.

Table 2

Default Organic HAP Mass Fraction for Solvents and Solvent Blends

You may use the mass fraction values in the following table for solvent blends for which you do not have test data or manufacturer’s formulation data and which match either the solvent blend name or the chemical abstract series (CAS) number. If a solvent blend matches both the name and CAS number for an entry, that entry’s organic HAP mass fraction shall be used for that solvent blend. Otherwise, use the organic HAP mass fraction for the entry matching either the solvent blend name or CAS number, or use the organic HAP mass fraction from Table 3 of this subchapter if neither the name or CAS number match.

Table 3

Default Organic HAP Mass Fraction for Petroleum Solvent Groups a

You may use the mass fraction values in the following table for solvent blends for which you do not have test data or manufacturer’s formulation data.
