(4) The lead emission rate in pounds per quarter is calculated by multiplying the quarterly lead emission rate in pounds per hour by the quarterly plant operating time, in hours as shown in Equation 1: View Image
Where:
EPb = quarterly lead emissions, pounds per quarter;
ERPb = quarterly lead emissions rate, pounds per hour; and
QPOT = quarterly plant operating time, hours per quarter.
(6) To determine compliance with the production-based lead compound emission rate in § 63.1543(a) , the quarterly production-based lead compound emission rate, in units of pounds of lead emissions per ton of lead produced, is calculated as shown in Equation 2 by dividing lead emissions by lead production.

Where:
CEPb = quarterly production-based lead compound emission rate, in units of pounds of lead emissions per ton of lead produced;
EPb = quarterly lead emissions, pounds per quarter; and
PPb = quarterly lead production, tons per quarter.
