# §63.5753. How do I calculate the combined organic HAP content of aluminum wipedown solvents and aluminum recreational boat surface coatings?

- (a) Use equation 1 of this section to calculate the combined weighted-average organic HAP content of aluminum wipedown solvents and aluminum recreational boat surface coatings.
- (b) **Compliance is based on a 12-month rolling average.** If the combined organic HAP content does not exceed 1.55 kilograms of organic HAP per liter of total coating solids, then you are in compliance with the emission limit specified in [§ 63.5743(a)(3)](/cfr/40/63.5743.md?p=a-3).
