NR 465.48(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 465.48(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 465.48(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.

Operating Limits if Using the Emission Rate With Add-On Controls Option in s. NR 465.43 (2) (c)

If you are required to comply with operating limits by s. NR 465.43 (3) (b), you shall comply with the applicable operating limits in the following table.

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.
