On 16 June 2010, the 45-day Public <br /> Participation was completed with no comments received by this agency. <br /> The NOI describes the discharge of injected ozone into groundwater from an ozone generation and <br /> injection system. The treatment system has been designed to remove petroleum hydrocarbon <br /> contaminants, including methyl tertiary butyl ether (MTBE), in groundwater. In addition to ozone, mildly <br /> acidic amendments such as vinegar or citric acid may be used in the ozone injection points to control <br /> biofouling. <br /> The General Order includes a Monitoring and Reporting Program (MRP) that prescribes minimum <br /> monitoring requirements. The MRP requires sampling and analytical testing for specific petroleum <br /> hydrocarbon and secondary constituents in monitoring wells. Additions and/or modifications to the <br /> MRP are included in the Additional Requirement section of this Notice of Applicability (NOA). <br /> Based on our review of the information provided, we have determined this project meets the required <br /> conditions to be approved under the General Order. All requirements contained in the General Order <br /> and/or modified by this NOA are applicable to your project.
