Such increased frequency shall also be indicated. <br />b. Oil and Grease Monitorine <br />For every ouffall with oil and grease monitoring, in the event an oil sheen or floating oil is observed, a grab sample shall be <br />collected, analyzed, and reported on [he appropriate DMR. In addition, corrective action shall be taken immediately to mitigate <br />the discharge of oil and grease. A description of the corrective action taken should be included with the DMR. <br />2. Salinity Parameters <br />In order to obtain an indication of the quantity of Salinity, measwed as total dissolved solids (TDS), being dischazged from the site <br />the permittee shall monitor the wastewater effluent at the following frequencies: <br />was re uenc am e e <br />- I uarter ra <br />Self-monitoringg samples taken in compliance with the monitoring requirements specified above shall be taken at those locations <br />listed in Part LB.1. <br />Where, based on a minimum of 5 samples, the permittee demonstrates to the satisfaction of the Division that the level of total <br />dissolved solids.(TDS) in the effluent can be calculated based upon the level of eiectncal conductivity, the pennittee may measure <br />and report TDS m terms of electrical conductivity. <br />C. DEFIAIITIONS OF TERMS <br />1. "Acute Toxicity" means there shall be no acute toxici. m the effluent from the app]icable dischar a point. The acute toxicity <br />limitation is exceeded rf 11 a statistically_sigmficant d~erence m mortahtvf{at the 95% confidenceglevel) is observed for either <br />specles between the control and any dilution less that or equal to the iden ~ red IWC or 2) a species mortality in any dilution of <br />effluent (including 100% effluent) exceeds 50%. <br />2. "Chronic lethality" occws when a statistically si ficant difference, at the 95% confidence level, occws in the chronic test between <br />[he mortality of the test species m 100% effluent~e chronic IWC = 100%) and the control. <br />3. "Co osite" sample is a minimum of fow (4) grab samples collected at equally spaced two (2) how intervals and proportioned <br />according to flow. <br />4. "Continuous" measwement, is a measwement obtained from an automatic recording device which continually measwes provides <br />measwements. <br />S. "Daily Maximum limitation" means the limitation for this pazameter shall be applied as an instantaneous maximum (or for H or <br />DO instantaneous tnimmum) value. The instantaneous value is defined as the analy~cal result of an mdivrdual sample. )MRS <br />shah include the maximum (and/or minimum) of all, instantaneous values within the calendar month Any uistantaneous value <br />beyond the noted daily maximum limitation for the indreated parameter shall be considered a violation of this permit. <br />6. "Dissolved (D) metals fraction" is defined in the Basic Standards and Methodolo ies for Surface Water 1002-31, as that portion of a <br />water and suspended sediment sample whic~ passe ou a or micron mem rane filter. Determinations of <br />dissolved" constimen[s are made usm the fi trate. This may include some very sma ](colloidal) suspended particles which passed <br />through the membrane filter as well as fie amount of substance present in true chemical solution. <br />7. "Grab" sample, is a single "dip and take" sample so as to be representative of the pazameter being monitored. <br />8. "In-situ" measwement is defined as a single reading, observation or measwement taken in the field at the point of discharge. <br />9. "Instantaneous" measurement is a single reading, observation, or measurement performed on site using existing monitoring facilities. <br />10. "Potentially dissolved (PD) metals fraction" is defined in the Basic Standards and Methodolo ies for Surface Water 2002-31, as. that <br />portion of a constituer~tt measwed from the filtrate of a water an suspen a se tmen samep e a was ors ea a with nitric acrd to <br />a pH of 2 or less and let stand for 8 to 96 hours prior to sample filtration using a 0.40 or U 4S-UM (mtcron) membrane filter. Note <br />the "potentially dissolved" method cannot be used where nitric acid will mterfere with the analytical procedwe used for the <br />consutuent measwed. <br />1 l . "Quarterly measwement freqquencyy means samples may be collected at any time during the calendar quarter if a continua] discharge <br />occws. If the discharge is intemvttent, then samples shall be collected during the period that discharge occws. <br />12. "Recorder" requires the continuous operation of a chart and/or totalizer (or drinking water rotor meters or pump how meters where <br />previously approved.) <br />Revised 1/J42005 <br />
