Groundwater VOC and Fuel General Permit ORDER NO.R2-2012-0012 <br /> NPDES NO.CAG912002 <br /> Pollutant Chemical Abstract Service Trigger <br /> (CAS)Number (µg/L)�'�°�Z� <br /> detection level shall be explained within the monitoring report.In case of Bunker C Fuel,any non-detect result with <br /> reporting levels not exceeding 100µg/L will not be deemed to be out of compliance with the 50 ug/L trigger level. <br /> 7. Trigger Case 1: If the results of all three additional discharge samples do not exceed the <br /> triggers, the Discharger shall report the results in the next Monitoring Report and shall return <br /> to the schedule of sampling and analysis in the attached Monitoring and Reporting Program <br /> (Attachment E). <br /> 8. Trigger Case 2: If the results of at least one of the three additional discharge samples show <br /> exceedance of the same trigger, the Discharger shall investigate the source (e.g., comparing <br /> influent and discharge sample results) and investigate source control and/or treatment options <br /> for each triggered pollutant. The Discharger shall document its progress on these efforts in <br /> the Annual Self-Monitoring Report required by section IX.B of the Monitoring and <br /> Reporting Program(Attachment E). Until the Executive Officer detertnines that the <br /> "triggered pollutants" investigation is complete, the Discharger must implement the <br /> following monitoring schedule for the triggered pollutants: <br /> a. In case of a triggered inorganic pollutant, the Discharger shall accelerate monitoring of <br /> the discharge to quarterly and provide information,updated annually, confirming that <br /> pollutant source is background and explain the reasons why treatment of that pollutant is <br /> not feasible. Specifically, the annual monitoring reports shall include site-specific <br /> background groundwater concentrations,types of treatment available, and costs of <br /> treatment systems for each triggered inorganic pollutant, and <br /> b. In case of a triggered organic pollutant, the Discharger shall accelerate monitoring of the <br /> discharge to every two weeks and provide information,updated annually, confirming the <br /> reason(s) why that pollutant could not be treated to the level not exceeding the trigger for <br /> that pollutant. <br /> 9. The Executive Officer may require the Discharger to perform additional investigations or <br /> take additional actions if the Discharger: (1) exceeds a trigger value for the same pollutant <br /> and confirms (Trigger Case 2 above)the exceedance greater than two times in one calendar <br /> year; and(2) is not pursuing resolution of trigger exceedances in a timely fashion in the <br /> judgment of the Executive Officer. These two trigger exceedances do not include the data <br /> collected to verify the trigger(i.e., effluent data collected to confirm the trigger exceedance). <br /> These conditions are also grounds for termination of the Authorization to Discharge. <br /> 10. Individual NPDES Permit May Be Required.The USEPA Administrator may request the <br /> Regional Water Board Executive Of�cer to require any Discharger authorized to discharge <br /> waste by the General Permit to apply for and obtain an individual NPDES permit. The <br /> Executive Officer may require any Discharger authorized to discharge waste by the General <br /> Permit to apply for and obtain an individual NPDES permit. Cases where an individual <br /> NPDES permit may be required include the following: <br /> 17 <br /> Limitations and Discharge Requirements <br />
