Description of Steps Taken: FINAL 7/13/2011 (LS) Due to heavy rains/high flows

through the plant, there was a failure at the UV control

panel, and the 2nd UV channel did not come on line

automatically. The 2nd channel was manually brought on

line. During this time (approximately 10 minutes), a small

portion of wastewater effluent flowed above the UV bulbs,

bypassing the UV disinfection. Both UV channels are

currently on line in manual mode. Sign posting, monitoring

or receiving water, and press release waived by CWB.
