w i INFORMATION SHEET 3 WASTE DISCHARGE REQUIRMENTS ORDER NO.R5-2003-XXXX LINCOLN CENTER ENVIRNMETNAL REMEDIATION TRUST IN SITU GROUNDWATER REMEDIATION PILOT STUDY,SAN JOAQUIN COUNTY State Board Resolution No. 68-16 (hereafter Resolution 68-16 or the "Anti-degradation Policy") requires the Board, in regulating the discharge of waste, to maintain high quality waters of the state until it is demonstrated that any change in quality will be consistent with maximum benefit to the people of the State, will not unreasonably affect beneficial uses, and will not result in water quality less than that described in the Board's policies (e.g., quality that exceeds water quality objectives). Temporal, short-term degradation of the groundwater by GZVI injection may occur in a limited portion of the aquifer near the injection points. Such degradation is consistent with Resolution 68- 16 since (a) the purpose of the discharge is to implement the cleanup of groundwater pollution and such remediation will benefit the people of the State; (b) the discharge as allowed in this Order is a pilot project to evaluate the effectiveness and is limited in scope and duration; (c) this Order requires use of best practicable treatment, including adequate monitoring and contingency plans to assure protection of water quality; and (d) this Order does not allow discharges of waste to exceed water quality objectives other than those temporarily permitted by these WDRs. The discharger is required to remove injected waste constituents and byproducts using the existing groundwater extraction system in the event groundwater degradation occurs as a result of the discharge. The proposed Order prohibits the discharge of wastes in any manner other than that described in the Findings of the Order, including prohibiting discharge of waste to surface waters or discharge of hazardous waste. The Order requires monitoring and reporting on the results of the pilot study. i I i
