LIBBEY-OWENS-FORD COMPANY <br /> LATHROP PLANT 110. 10 <br /> SAN JOAQUIN COUNTY <br /> 6. The discharger shall comply with the Monitoring and Reporting Program <br /> No. 74-474 and the General Provisions for Monitoring and Reporting <br /> as specified by the Executive Officer. <br /> 7. This Order expires on 1 October 1979 and the Libbey-Owens-Ford Company <br /> must file a Report of Waste Discharge in accordance with Title 23, Califor- <br /> nia Administrative Code, not later than 180 days in advance of such date as <br /> application for issuance of new waste discharge requirements. <br /> 8. In the event of any change in control or ownership of land or waste dis- <br /> charge facilities presently owned or controlled by the discharger, the <br /> discharger shall notify the succeeding owner or operator of the existence <br /> of this Order by letter, a copy of which shall be forwarded to this office. <br /> 9. The daily discharge rate is obtained from the following calculation for <br /> any calendar day: <br /> Daily discharge rate = 8_34 N QC. <br /> N � i i <br /> 1 <br /> in which N is the number of samples analyzed in any calendar day. Qi and Ci <br /> are the flow rate (MGD) and the constituent concentration (mg/1) respec- <br /> tively, which are associated with each of the N grab samples which may be <br /> taken in any calendar day. If a composite sample is taken Ci is the con- <br /> centration measured in the composite sample, and Qi is the average flow <br /> rate occurring during the period over which samples are composited. <br /> The 30-day average discharge rates shall be the arithmetic average of all <br /> the values of daily discharge rate calculated using the results of analyses <br /> of all samples collected during any 30 consecutive calendar day period <br /> respectively. If fewer than four samples are collected and analyzed during <br /> any 30 consecutive calendar day period, compliance with the 30-day average <br /> discharge rate limitation shall not be determined. <br /> The daily maximum concentration shall be determined from the analytical <br /> results of any sample, whether discrete or composite. <br /> I, JAMES A.
