Is containment area adequate (free of leaks etc.)? Comment:The chlorine contact tank sludge depth was approximately 1 foot in areas. The chlorine contact tank should be cleaned as soon as possible. Our office recommends the sludge depth to be less than 1 foot in all areas of the tank. De -chlorination Is the feed ratio proportional to chlorine amount (1 to 1)? Is storage appropriate for cylinders? Is de -chlorination substance stored away from chlorine containers? Is ventilation operational? Comment:ln previous inspection reports dated July 27, 2000, May 29, 2001 and March 27, 2002, it was noted that both chlorine and sulfur dioxide were located side by side in the same room without any division. These gases located side by side can create a hazardous area. Standby Power Is automatically activated standby power available? Is generator tested weekly by interrupting primary power source? Is generator tested under load at least quarterly? Was generator tested & operational during the inspection? Do the generator(s) have adequate capacity to operate the entire wastewater site? Does generator have adequate fuel? Is there an emergency agreement with a fuel vendor for extended run on back-up power? Comment: agnnns Type of lagoons?

Are dikes free of erosion? Are dikes free of burrowing animals? Are sludge levels appropriate? Has the sludge blanket in the lagoon (s) been measured periodically in multiple locations? If excessive algae is present, has barley straw been used to help control the growth? • Is the lagoon surface free of weeds? Is the lagoon free of short circuiting?
