Question: Since dewatering will be required based on the ground water elevation, can the ground water be disposed of in the sewer system after desilting? If the surrounding soil is contaminated, so may be the ground water. Treatment of ground water is very difficult quantity in regard to costs. Please clarify where ground water can be disposed of, any fees and how treatment will be paid if required.

Response: The contractor is responsible for characterization of all solid wastes, liquid wastes, and imported fill materials as described in Article 1.4. A. EBMUD Engineer will review laboratory analysis results for EBMUD acceptance of Contractor Characterization of waste classification. Contractor will manage and transport materials and/or wastes in accordance with all local, state, and federal laws, rules, and regulations. The contractor shall submit a detailed Water Control and Disposal Plan for the EBMUD Engineer's acceptance prior to any work at the jobsite. The Plan shall describe measures for containment, handling, treatment (as necessary), and disposal of discharges such as groundwater (if encountered), runoff of water used for dust control, stockpile leachate, tank heel water, wash water, sawcut slurry, test water and construction water or other liquid that has been in contact with any interior surfaces of EBMUD facilities. The groundwater can be discharged into the Sewer System; however, this will require that the contractor first submit and acquire a special discharge permit. Discharges destined for EBMUD’s main wastewater treatment plant in Oakland, shall reference Special Discharge Permit (SDP) Application SD-035 and the associated SDP Terms and Conditions, when obtaining authorization from the pertinent local jurisdiction that owns the sewers to be used. Contractor shall, prior to the end of the Work, report to the Engineer the volumes of all discharges performed pursuant to the said SDP along with copies of any profile forms and/or correspondence between Contractor and disposal facility. Contractor must adhere to all permit requirements. For more information on how to apply for the special sewer discharge permit please visit https://www.ebmud.com/wastewater/commercial-waste/permits-and-wastewater-discharges. EBMUD's Wastewater Control Ordinance regulates wastewater discharges into our wastewater system and includes discharge limits (local limits) for select pollutants. Local Limits for typical chemicals of concerns are provided here: https://www.ebmud.com/wastewater/collection-treatment/wastewater-control-ordinance-discharge-limits. Required waste characterization for potentially contaminated groundwater are not limited the chemicals of concern and analyses shown in the Ordinance summary table. Wastewater characterization requirements are site specific. ACC Environmental Consultants, Inc. (ACC) prepared this Soil and Groundwater Characterization Report at the request of Peralta Community College District (PCCD) to adreess EBMUD's concerns. The completed soil and water characterization for the pipeline site will be shared with prospective bidders for the purpose of cost estimating anticipated soil and groundwater treatment, handling and disposal efforts accordingly. See: Sample Location Pipeline EBMUD, SD-035 Special Discharge Permit and March 2017 SDP TC in Project Documents.
