<br />9 <br />Honeywell International Industrial Discharge Permit <br /> <br />screening table in Part I (3) below. If pollutant concentrations above the screening levels are observed, a local Daily Maximum <br />and/or Monthly Average limit may be developed for that pollutant. <br /> <br />Please be aware that Federal Categorical Limits are still in effect, as required by 40 CFR 433 15. For pollutants that do not have <br />local limits in the table above, the permittee is still required to comply with any applicable categorical standards, below. <br />Parameter Daily Maximum (mg/L) Monthly Average Limit (mg/L) <br />Cadmium (mg/L)* 0.69 0.26 <br />Lead (mg/L)* 0.69 0.43 <br />Silver (mg/L)* 0.43 0.24 <br /> <br />a. Daily Maximum Limit means the maximum allowable discharge limit of a <br />pollutant during a calendar day or any 24-hour period that represents a calendar <br />day. Where Daily Maximum Limits are expressed in units of mass, the daily <br />discharge is the total mass discharged over the course of the day. Where Daily <br />Maximum Limits are expressed in terms of a concentration, the daily discharge <br />is the arithmetic average measurement of the pollutant concentration derived <br />from all measurements taken that day. In the case of samples collected by the <br />grab method, the daily maximum shall be applied as an Instantaneous <br />Maximum Allowable Discharge Limit or as an Instantaneous Minimum <br />Allowable Discharge Limit as follows: <br /> <br />i. Instantaneous Maximum Allowable Discharge Limit – shall mean the <br />maximum concentration or loading of a pollutant allowed to be <br />discharged at any time, determined from analysis of any discrete or <br />composite sample collected, independent of the industrial flow rate and <br />the duration of the sampling event. <br /> <br />ii. Instantaneous Minimum Allowable Discharge Limit – shall mean the <br />minimum concentration of a pollutant allowed to be discharged at any <br />time, determined from analysis of any discrete or composite sample <br />collected, independent of the industrial flow rate and the duration of the <br />sampling event. The lower pH limit is applied as an Instantaneous <br />Minimum Allowable Discharge Limit. <br /> <br />b. Monthly Average Limit means the maximum allowable average of daily <br />discharges over a calendar month, calculated as the sum of the concentrations <br />of all daily discharges measured during a calendar month divided by the <br />number of daily discharges measured that month.
