and make available to the Administrator upon request a file of the 
following records:
    (1) All measurements, including continuous monitoring for

    (2) Records of emission test data and all calculations used to 
produce the required reports of emission estimates to demonstrate 
complaince with Sec. 61.172(c);
    (3) All continuous monitoring system performance evaluations, 
including calibration checks and adjustments;
    (4) The occurrence and duration of all startups, shutdowns, and

weight percent of arsenic contained in the copper matte and lead matte 
as determined under Sec. 61.174(f).
    (3) For each copper converter department, the monthly calculations 
of the average annual arsenic charging rate for the preceding 12-month 
period as determined under Sec. 61.174(f).
