§63.5330. How do I determine the compliance ratio? — Inbound Citations

(8) Determine the compliance ratio for your affected source each month as specified at § 63.5330. The compliance ratio compares your actual HAP loss to your allowable HAP loss for the previous 12 months.

(d) After collecting HAP loss data for 12 months, you must also determine by the fifteenth of each month the annual HAP loss in pounds by summing the monthly HAP losses for the previous 12 months. The annual HAP loss is the “actual HAP loss,” which is used in Equation 1 of § 63.5330 to calculate your compliance ratio, as described in § 63.5330.

(c) The resulting “allowable HAP loss” is used in Equation 1 of § 63.5330 to calculate your compliance ratio, as described in § 63.5330.

(3) You must maintain your compliance ratio less than or equal to 1.00, as specified at § 63.5330.

(2) By the fifteenth of each month, you must determine the quantity of leather processed in 1,000's of square feet for each product process operation during the previous month. After collecting data on the amount of leather processed for 12 months, you must also determine by the fifteenth of each month the annual total of leather processed in 1,000's of square feet for each product process operation by summing the monthly quantities of leather processed in each product process operation for the previous 12 months. The “annual total of leather processed” in each product process operation is used in Equation 1 of § 63.5340 to calculate your allowable HAP loss as described in § 63.5340. Your allowable HAP loss is then subsequently used to calculate your compliance ratio as described in § 63.5330.

(b) You must submit a Deviation Notification Report for each compliance determination you make in which the compliance ratio exceeds 1.00, as determined under § 63.5330. Submit the deviation report by the fifteenth of the following month in which you determined the deviation from the compliance ratio. The Deviation Notification Report must include the items in paragraphs (b)(1) through (6) of this section:

(3) The 12-month period covered by the report and each type of leather product process operation performed during the 12-month period.

(4) You may reduce the frequency of submittal of the Deviation Notification Report if the Administrator of these NESHAP approves an alternative schedule.

(5) An estimate of the quantity of HAP (in pounds) emitted during the 12 months specified in paragraph (b)(3) of this section in excess of the allowable HAP loss. Calculate this estimate of excess emissions by subtracting the allowable HAP loss determined as specified in § 63.5340 from the actual HAP loss determined as specified in § 63.5335.

(6) The cause of the events that resulted in the source failing to meet an applicable standard (including unknown cause, if applicable).

(h) In the event that the compliance ratio exceeded 1.00, as determined under § 63.5330, keep a record of the information specified in paragraphs (h)(1) through (5) of this section for each exceedance.

(1) The 12-month period in which the exceedance occurred, as reported in § 63.5420(b).

(2) Each type of leather product process operation performed during the 12-month period in which the exceedance occurred, as reported in § 63.5420(b).

(3) Estimate of the quantity of HAP (in pounds) emitted during the 12 months specified in § 63.5420(b)(3) in excess of the allowable HAP loss, as reported in § 63.5420(b).

(4) Cause of the events that resulted in the source failing to meet an applicable standard (including unknown cause, if applicable), as reported in § 63.5420(b).

(5) Actions taken to minimize emissions in accordance with § 63.5320(b), and any corrective actions taken to return the affected unit to its normal or usual manner of operation.

(i) Any records required to be maintained by this part that are submitted electronically via the EPA's CEDRI may be maintained in electronic format. This ability to maintain electronic copies does not affect the requirement for facilities to make records, data, and reports available upon request to a delegated air agency or the EPA as part of an on-site compliance evaluation.
