Daily dischargeThe discharge of a pollutant measured during a calendarday or any 24-hour period that reasonably and accurately represents the calen-dar day for purposes of sampling:
(i) For pollutants with limitations expressed in units of mass, the dailydischarge is calculated as the total mass of the pollutant discharged over theday.
(ii) For pollutants with limitations expressed in other units of measure-ment, the daily discharge is calculated as the average measurement of thepollutant over the day.DischargeAn addition of any pollutant to surface waters of this Common-
wealth from a point source.Disturbed areaAs defined in Chapter 102 (relating to erosion and sediment
control).Draft permitA document prepared by the Department indicating the
Departments tentative decision to issue or deny, modify, revoke or reissue apermit.

or the Administrator on quantities, rates and concentrations of chemical, physi-cal, biological and other constituents which are discharged from point sourcesinto surface waters, including BMPs and schedules of compliance.
