Libbey Owens Ford Compano - 2 - • 7 July 1999 Order No. 91-056 includes effluent limitations for discharges to land. Effluent limitation A.1 requires, in part,that total coliform organisms not exceed 23 MPN/100 ml as a daily maximum. Effluent limitation A.7. states: "Reclaimed wastewater used for lawn irrigation shall meet the criteria contained in Title 22, California code of Regulations (Section 60301, et. seq.). Section 60313 of Title 22 requires that: "Reclaimed water used for the irrigation of p�rks, playgrounds, schoolyards, and other areas where the public has similar access or exposure shall be at,all times an adequately disinfected, oxidized, coagulated, clarified, filtered wastewater or a wastewater treated by a sequence of unit processes that will assure an equivalent degree of treatment and reliability. The wastewater shall be considered adequately disinfected if the median number of coliform organisms in the effluent does not exceed 2.2 per 100 milliliters, as determined from the bacteriological results of the last 7 days for which analyses have been completed, and the number of coliform organisms does not exceed 23 per 100 milliliters in any sample." The package plant which treats the sanitary wastewater generated at LOF does not provide equivalent treatment to that specified in Section 60313. I spoke with Jon Weiss about the need to fence the lawns to prevent public access, or to cease irrigation of those areas with effluent containing sanitary wastewater. For areas within the plant site, employees must be informed that reclaimed water is in use, and educated to take proper precautions to prevent exposure. Following the inspection I reviewed self-monitoring reports from January through May 1999. The wastewater exceeded 23 MPN/100 ml four times in five months,based on weekly sampling results. LOF recently made upgrades to the sanitary treatment plant in order to improve the disinfection of the wastewater. However,periodic violations are continuing. SUMMARY: There has been no discharge to the San Joaquin River from LOF over the term of its NPDES permit. All wastewater is reclaimed on property under the control of the Discharger. The Discharger has irrigated lawns with water which does not comply with Section 60313, Title 22, California Code of Regulations. The Discharger must either fence areas receiving reclaimed water so that public access is prevented, or cease irrigation of those areas with effluent containing sanitary wastewater. The employees at LOF must also be informed as to proper precautions to prevent exposure from reclaimed water use inside the facility. Patricia Leary,Associate E ter
