adequacy of the proposed treatment system in removal of all organic pollutants of <br /> concern. Based on these data and information,the Discharger may receive a discharge <br /> authorization letter. However, some organic compounds, other than pollutants with <br /> effluent limitations,may be detected in the effluent of some of the treatment systems. <br /> This could be due to the movement of the contaminated groundwater from a neighboring <br /> site into the capture zone of the treatment facility authorized under this permit. Table F-8 <br /> contains concentration-based triggers for conducting additional activities for a list of <br /> pollutants reported by Dischargers or listed in the CTR. This provision would allow <br /> Dischargers to continue groundwater cleanup while investigating the ability to treat any <br /> detected volatile or semi-volatile organic compounds, in excess of Table F-8 triggers. <br /> Table F-8.
