<br /> 27. "Measurable storm event" -a storm event that results in an actual discharge from the facility.
<br /> 28. "Minimize"-reduce and/or eliminate to the extent achievable using control measures(including best management practices)
<br /> that are technologically available and economically practicable and achievable in light of best industry practice.
<br /> 29. "Minimum level (ML)" means the lowest concentration of an analyte that can be accurately and precisely quantified using a
<br /> given method,as determined by the laboratory.
<br /> 30. "New Discharger"-means any building,structure,facility,or installation from which there is or may be a discharge of pollutants
<br /> that did not commence at the particular site before August 13, 1979,that is not a new source,and that has never received a
<br /> final effective permit for discharges at the site.See 5 CCR 1002-61.2(65).
<br /> 31. "NOEC"or"No-Observed-Effect-Concentration"is the highest concentration of toxicant to which organisms are exposed in a full
<br /> life cycle or partial life cycle(short term)test,that causes no observable adverse effects on the test organisms(i.e.the highest
<br /> concentration of toxicant in which the values for the observed responses are not statistically different from the controls). This
<br /> value is used,along with other factors,to determine toxicity limits in permits.
<br /> 32. "No exposure"—all industrial materials or activities are protected by a storm-resistant shelter to prevent exposure to rain,
<br /> snow,snowmelt,and/or runoff. 5 CCR 1002-61.3(2)(h).
<br /> 33. "Person"-an individual,corporation,partnership,association,state or political subdivision thereof,federal agency,state
<br /> agency, municipality,Commission,or interstate body.See 5 CCR 1002-61.2(73).
<br /> 34. "Point source"-any discernible,confined,and discrete conveyance,including, but not limited to,any pipe,ditch,channel,
<br /> tunnel,conduit,well,discrete fissure,container,rolling stock,concentrated animal feeding operation,or vessel or other floating
<br /> craft,from which pollutants are or may be discharged."Point Source"does not include irrigation return flow.See 5 CCR 1002-
<br /> 61.2(75).
<br /> 35. "Pollutant"-dredged spoil,dirt,slurry,solid waste, incinerator residue,sewage,sewage sludge,garbage,trash,chemical waste,
<br /> biological nutrient,biological material, radioactive material, heat,wrecked or discarded equipment, rock,sand,or any industrial,
<br /> municipal or agricultural waste.See 5 CCR 1002-61.2(76).
<br /> 36. "Potentially dissolved(PD) metals fraction"is defined in the Basic Standards and Methodologies for Surface Water 1002-31,as
<br /> that portion of a constituent measured from the filtrate of a water and suspended sediment sample that was first treated with
<br /> nitric acid to a pH of 2 or less and let stand for 8 to 96 hours prior to sample filtration using a 0.40 or 0.45-UM(micron)
<br /> membrane filter. Note the"potentially dissolved" method cannot be used where nitric acid will interfere with the analytical
<br /> procedure used for the constituent measured.
<br /> 37. "Practical Quantitation Limit(PQL)" means the minimum concentration of an analyte(substance)that can be measured with a
<br /> high degree of confidence that the analyte is present at or above that concentration. The use of PQL in this document may refer
<br /> to those PQLs shown in Part LE of this permit or the PQLs of an individual laboratory.
