1.0 DEFINXTIONS Accura _cy:
Refers to the deviation of a result obtained by a particular method from the value accepted as true.
Aerial Remote Sensing:
The measurement or acquisition from aircraft or spacecraft of information on some property of an object or phenomenon by a recording device that is not in physical or intimate contact with the object or phenomenon under study.
The technique employs such devices as the camera, radio frequency receivers, and radar systems.
Annually: Annually is once per calendar year at intervals of twelve calendar months, plus or minus 30 days.
Batch Release: A batch release is the discharge of fluid wastes of a discrete volume.
Calibration: An instrument or device calibration shall be the i
adjustment, as necessary, of the output such that it responds with the necessary range and accuracy to known values of the parameter (s) which i
(
the instrument sensor or device monitors.
The calibration shall encompass the entire circuit including the sensor, indicatory control i
feature, alarm and/or trip function (s), and shall include the Channel l
Functional Test.
The calibration may be performed by any series of sequential, overlapping or total circuit steps such that the entire circuit is calibrated as specified.
I Channel Check: A qualitative assessment of channel Lehavior during l
operation by observation.
This determination shall include, where possible, comparison of the channel indication and/or status with other i
indication and/or status derived from independent instrument channels measuring the same parameter."
i Channel Functional Test:
l a.
Analog channels - the injection of a simulated signal into the l
channel as close to the primary sensor as practicable to verify I
OPERABILITY including alarm and/or trip functions, b.
81 stable channels - the injection of a simulated signal into the channel sensor to verify OPERABILITY including alarm and/or trip functions.
Closed Cycle Cooling:
The condenser cooling method in which the circulating water, af ter passing througii cooling towers, in recirculated back to the condenser intake with the exception of the blowdown which is discharged to the receiving water body.
Combined Available Chlorine:
Chlorine existing in water in chemical combination with ammonia or organic nitrogen compounds.
l l-1 8804080080 880404
-gDR ADOCK0500go
Composition ~ Sample: A combination of individual samples obtained at regular intervals over a time period.
Either the volume of each Individual sample is proportional to the flow rate discharge at the time of sampling or the number of equal volume samples is proportional to the time period used to produce.the composite.
Continuous Release: A continuous release is the discharge of fluid waste of a non-discrete volume, e.g., from a volume or system that has an input flow during the continuous release.
Daily Average Concentration:
Daily average concentration means the arithmetic average of all daily determinations of concentration made during a calendar month. Daily determinations of concentration using a composite sample shall be the concentration of the composite sample.
When grab samples are used, the daily determination of concentration shall be the arithmetic average of all the samples collected during that calendar day.
Daily Maximum Concentration:
Daily maximum concentration means the maximum concentration recorded for any calendar day.
Free Available Chlorine: Chlorine existing in water as hypochlorous acid and hypochlorite ions.
Grab Sample: A grab sample in an individual sample collected in less than fifteen minutes.
I Ground Truth or Ground Data Surveys:
Supporting data collected on the ground and information derived therefrom, as an aid to the interpretation of remotely-recorded survey, such as aerial imagery, etc.
Generally, this should be performed concurrently with the airborne surveys.
