INFORMATION SHEET FOR ORDER NO. -6- LINNE ESTATES,LLC LINNE ESTATES WASTEWATER TREATMENT SYSTEM SAN JOAQUIN COUNTY preventable through appropriate system design and operation. The proposed groundwater limitations for pH, iron, manganese, and ammonia apply the water quality objectives. Title 27 Title 27 California Code of Regulations (CCR) Section 20005 et seq. ("Title 27"), contains regulations to address certain waste discharges to land for treatment, storage, processing, or disposal. Title 27 establishes a waste classification system, specifies siting and construction standards for full containment of designated and non-hazardous wastes, requires extensive monitoring of groundwater and the unsaturated zone for any indication of failure of containment, and specifies closure and post-closure maintenance requirements. Generally, no degradation of groundwater quality by any waste constituent is acceptable. Discharges of domestic sewage and treated effluent can be treated and controlled to a degree that will not result in unreasonable degradation of groundwater. For this reason, they have been conditionally exempted from Title 27, except for the discharge to land of residual sludge and solid waste generated as part of the treatment process [Title 27 Section 20090(a)]. The conditions require that Waste Discharge Requirements (WDRs) have been issued or waived and that the discharge not result in violation of any water quality objective in groundwater. Treatment and storage facilities for sludge that are part of the WWTF are considered exempt from Title 27 under Section 20090(a), under the condition that the facilities not result in a violation of any water quality objective. However, residual sludge (for the purposes of the proposed order, sludge that will not be subjected to further treatment by the WWTF is not exempt from Title 27. Solid waste(e.g., grit and screenings) that results from treatment of domestic sewage and industrial waste also is not exempt from Title 27. This residual sludge and solid waste are subject to the provisions of Title 27. Accordingly, the municipal discharge of effluent and the operation of treatment or storage facilities associated with a municipal wastewater treatment plant can be allowed without requiring compliance with Title 27, but only if resulting degradation of groundwater is in accordance with all water quality objectives. The conditions for sludge, solid waste, and biosolids management proposed in this Order are intended to assure this be evaluated along with other aspects of BPTC, pursuant to Resolution No. 68-16. Discharge Prohibitions and Specifications The Report of Waste Discharge (RWD) and water balance states that the treatment system is adequate for the estimated flow of 55,000 gpd. This Order maintains the flow limit based on the RWD's description of the treatment system and dispersal area's capacity. Monitoring Requirements CWC Section 13267 authorizes the Regional Board to require monitoring and technical reports as necessary to investigate the impact of a waste discharge on waters of the state. In recent years there has been increased emphasis on obtaining all necessary information, assuring the information is timely as well as representative and accurate, thereby improving accountability of any discharger for meeting the conditions of discharge. CWC Section 13268 authorizes assessment of administrative civil liability
