Groundwater VOC and Fuel General Permit ORDER NO.R2-2012-0012 <br /> NPDES NO.CAG912002 <br /> ttp://www.waterboards.ca.gov/iswp/docs/final.pd�. If the Discharger cannot attain the reporting levels for Zinc,Arsenic,or Total Chromium, <br /> he reason(s)along with any supporting documentation shall be documented in the monitoring reports.Water Board sta£f shall make a <br /> ompliance determination based on data provided.If the Discharger exceeds the trigger for mercury of 0.025,the Discharger may consider re- <br /> ampling and re-analyzing another sample using ultra-clean techniques as described in USEPA methods 1669 and 1631 to eliminate the <br /> ossibility of artifactual contamination of the sample.For pollutants not listed in Appendix 4 of the SIP,the Discharger shall provide the reason <br /> or the higher detection level along with any supporting documentation in the monitoring reports. Water Board staff shall make a compliance <br /> etermination based on data provided. <br /> ote 3:Use techniques such as selective ion mode or isotope dilution to achieve reporting levels not exceeding 1 ug/1. <br /> efinitions:u L=microgram per liter or parts per billion(ppb);g/day=grams per day;gpm=gallons per minute;mg/L=milligram per liter <br /> r parts per million(ppm);gpd=gallons per day;MFL=million fibers per liter <br /> C=Gas Chromatography;GCMS=Gas Chromatography/Mass Spectrometry;FAA=Flame Atomic Absorption;GFAA=Graphite Fumace <br /> romic Absorption;Hydride=Gaseous Hydride Atomic Absorption;ICP=Inductively Coupled Plasma;and ICPMS=Inductively Coupled <br /> lasma/Mass Spectrometry. <br /> egends: <br /> D/NI Once during the first and fifth day of startup;monthly thereafter.For VOC,if a discharger has no VOC detected in the intluent or the <br /> effluent other than Total Petroleum Hydrocarbons,Benzene,Toluene,Ethylbenzene, Xylenes,Tertiary Amyl Methyl Ether(TAME), <br /> DiIsopropyl Ether(DIPE),Ethyl Tertiary Butyl Ether(ETBE),Tertiary Butyl Alcohol(TBA),Ethanol,or Methanol then frequency of VOC <br /> monitoring may be reduced to once a year. <br /> D/Q Once during the first and fifth day of startup;quarterly thereafter. <br /> Y Once during the first week of startup;annually thereafrer. <br /> 3Y Once during the first week of startup;every three years thereafter. <br /> 2/Y Once during[he first week of startup;twice per year thereafter. <br /> D/Y Once during the first and fifrh day of startup;annually thereafter. <br /> Q/Y Quarterly for first year of operation,annually thereafter. <br /> D/Q/Y Once during the first and fifth day of startup;quarterly for first year of operation,annually thereafter. <br /> D/M/Q/Y Once during the first and fifth day of startup;monthly for first year of operation,quarterly for the second year,and annually <br /> thereafter. In case of pH analysis,this monitoring requirement is only for facilities with a treatment process that would cause no pH variances <br /> in the effluenL If a�y chemical used in the treatment process may cause pH variances in the effluent,the frequency of pH monitoring in the <br /> effluent shall be increased to twice per week for the first month of operation and weekly thereafter if pH monitoring data for the first month of <br /> operation demonshate compliance with pH effluent limits. <br /> V Receiving Waters sampling must be performed together(on the same calendar day)with the required effluent confirmation sampling that is <br /> required when a violation of an effluent limit is known,and the sample analyzed for that specific viola[ed parameter and the Dissolved Oxygen <br /> level.In no case,should a Discharger continue discharging in known violation of effluent limits just to comply with this receiving water <br /> sampling requirement. <br /> T Sam lin shall be erformed when Cadmium,Chromium(total),Co er,Lead,Nickel,Silver,or Zinc tri ers are exceeded. <br /> VIII.OTHER MONITORING REQUIREMENTS <br /> A. Startup Phase Monitoring. During the original startup for the treatment system, sampling of the <br /> effluent must occur on the first day and fifth day of operation (weekend days may be excluded). <br /> 1. On the first day of the original startup, the system shall be allowed to run until at least three <br /> to five well volumes are removed and until three consecutive readings for pH, conductivity, <br /> and temperature are within five percent of each other; then,the influent and effluent shall be <br /> sampled and submitted for analyses. Prior to receipt of the results of the initial samples, all <br /> effluent shall be discharged into a holding tank(that is contained,not discharged to the <br /> receiving water) or discharged to the sanitary sewer until the results of the analyses show the <br /> discharge to be within the effluent limits established in this Order andlor as authorized by the <br /> Executive Officer. The treatment system may be shut down after the first day's sampling to <br /> await the analyses results and thereby reduce the amount of storage needed. If the treatrnent <br /> system is shut down more than 120 hours during the original startup(awaiting analyses <br /> results, etc.), the original stariup procedures and sampling must be repeated. For the stored <br /> effluent, if the results of the analyses show the discharge to be in violation, the effluent shall: <br /> (1) be retreated until the retreated effluent is in compliance, or(2)be disposed of in <br /> accordance with the applicable provisions of California Code of Regulations. <br /> 2. If the first day's sampling shows compliance, the treatment system shall be operated for a <br /> total of five days with the discharge to the storm sewer or other conveyance system leading <br /> to the receiving water, and be sampled again during the fifth day.
