WASTE DISCHARGE REQUIR]�%�NTS ORDER NO. -19- GOLDSTONE LAND COMPANY,LLC AND KURT KAUTZ BEAR CREEK WINERY SAN JOAQUIN COUNTY a. By 14 April 2003, the Discharger must submit a Notice of Intent to seek coverage under the National Pollutant Discharge Elimination System (NPDES) General Permit No. CAS000001 for Discharges of Storm Water Associated With Industrial Activities. b. At least 90 days before the Discharger wishes to discharge wastewater to new LTUs described in Finding No. 23 the Discharger shall submit a report describing completion of improvements to the designated LTUs to ensure compliance with this Order. The improvements shall include, but not be limited to, installation of fencing or notification signs, installation of berms to prevent surface water runoff from the LTUs, and installation of additional groundwater monitoring wells (in accordance with an approved workplan, as described in Provision G.2.e). c. By 13 May 2003, the Discharger shall submit certification that a flow metering system has been installed. The flow meter shall be designed to accurately measure flow to the LTUs and shall provide cumulative flow volume monitoring. d. By 12 June 2003, the Discharger shall submit certification that a pH control system has been installed. The system shall be designed to adjust the pH of the waste so that it continuously complies with the Discharge Specification CA. e. By 12 June 2003, the Discharger shall submit a workplan for characterization of groundwater quality for the LTUs. All active LTUs must be monitored. The workplan shall describe the installation of additional wells to allow evaluation of groundwater quality upgradient and downgradient of all LTUs. Monitoring wells shall be constructed to yield representative samples from the uppermost saturated interval and to comply with applicable well standards. The workplan shall be consistent with, and include the items listed in, the first section of Attachment C, "Items to be Included in a Monitoring Well Installation Workplan and a Monitoring Well Installation Report of Results." f. By 12 June 2003, the Discharger shall submit a Vadose Zone Monitoring Workplan. The workplan shall describe proposed vadose zone monitoring locations,proposed sampling techniques, and frequency of sampling designed to ensure that the free draining liquid within the vadose zone is representatively characterized. The purpose of this monitoring is to determine whether the land treatment units are sufficiently treating the wastewater such that the underlying groundwater will not be degraded. g. By 14 July 2003,the Discharger shall submit a Salinity Reduction Study Workplan. The workplan shall describe a plan for identifying high salinity waste streams and performing sampling and analysis to specifically characterize the salinity species of each high salinity waste stream. The study shall consider all aspects of winery waste, discuss alternate methods to reduce dissolved solids discharged to the LTUs, and present an implementation plan for the selected salinity reduction measure(s). h. By 14 July 2003,the Discharger shall submit an LTU Operation and Maintenance Plan for review and approval. The O&M Plan shall be prepared in accordance with V\.
