How do I determine the compliance ratio?

(a) When your source has processed leather for 12 months, you must determine the compliance ratio for your affected source by the fifteenth of each month for the previous 12 months. (b) You must determine the compliance ratio using Equation 1 of this section as follows: Where: Actual HAP Loss = Pounds of actual HAP loss for the previous 12 months, as determined in § 63.5335. Allowable HAP Loss = Pounds of allowable HAP loss for the previous 12 months, as determined in § 63.5340. (1) If the value of the compliance ratio is less than or equal to 1.00, your affected source was in compliance with the applicable HAP emission limits of this subpart for the previous month. (2) If the value of the compliance ratio is greater than 1.00, your affected source was deviating from compliance with the applicable HAP emission limits of this subpart for the previous month.
