            For the purposes of this Measure the following definitions shall apply:
        (1) Lead sampling must be carried out for a period of 24 hours at least every sixth day.
        (2) Measurement of lead must be carried out on Total Suspended Particles (TSP) or its equivalent.
        (3) In Column 3 of table 1 and Column 2 of tables 1A and 2 of Schedule 2, the averaging periods are defined as follows:
             * 1 hour clock hour average
             * 8 hour rolling 8 hour average based on 1 hour averages
             * 1 day  calendar day average
             * 1 year calendar year average
        (4)  All averaging periods of 8 hours or less must be referenced by the end time of the averaging period. This determines the calendar day to which the averaging periods are assigned.
        (5) For the purposes of calculating and reporting 8 hour averages, the first rolling average in a calendar day ends at 1:00 am, and includes hours from the previous calendar day.
        (6) The concentrations in Column 4 of table 1 and Column 3 of table 2 of Schedule 2 are the arithmetic mean concentrations.
