INFORMATION SHEET ORDER NO. R5-2015-0012 IN-SITU REMEDIATION OF GROUNDWATER AND DISCHARGE OF TREATED GROUNDWATER TO LAND comparability criteria and an exceedance not always verifiable. Water quality objectives for the anticipated pollutants that are found at these remediation projects are established in the Findings. The water quality objectives are established based on the numerical and narrative standards found in the Basin Plan. Coverage Under the Order To obtain coverage under the order, the project proponent must submit a Notice of Intent (N01) and supplemental information listed in Attachment A. The information requirements are significant as these projects are complex and require a great deal of knowledge about the project site and remediation processes. Though the requirement for submittal of information is substantial, it should be information that has already been developed by the project in order to justify the remediation project to the appropriate regulatory agency. In order for coverage to occur, the project proponent needs to demonstrate through laboratory-scale tests that the proposed project will adequately promote remediation of the pollution. The laboratory-scale tests will also be used to identify potential adverse water quality impacts with the project and help establish monitoring parameters. If there are data from projects sufficiently similar to the proposed project, the proponent can use that information in lieu performing the laboratory-scale testing, as appropriate. Once the project is completed, the project proponent will file for termination of coverage under the general order. Updates to Previous General Order R5-2008-0149 This General Order updates Order R5-2008-0149 in several ways. First, it establishes effluent limitations for discharges from groundwater treatment systems to ground. There are times when in-situ remediation systems extract groundwater, amend it and inject or infiltrate the amended water back into the groundwater. There can be some pollutants that that are not targeted by the in- situ remediation system and those pollutants may be required to be removed prior to discharge. The effluent limits are set at best available technology for removal of VOCs (effluent limit is 0.5 pg/L), at water quality objectives or background, whichever is greater, for pollutants such as perchlorate, chloride, TDS and other non-volatiles. This Order adds sulfate specifically to the list of pollutants that are covered and affirms that other pollutants can be considered once sufficient information has been supplied that verifies the efficacy of the proposed treatment method on the pollutant in the groundwater. Other changes were made to the monitoring program to improve its functionality and coverage of potential monitoring options.
