Ross Jr., Secretary Alan W. Klimek, P.E., Director Coleen H. Sullins, Deputy Director Division of Water Quality Enclosed you will find a copy of the Compliance Evaluation Inspection (CEI) report for the inspection conducted on October 31, 2005 at the Town of Robbins Wastewater Treatment Plant, accompanied by Brant Sikes, Town of Robbins ORC. As part of the inspection a tour of the Wastewater Treatment Plant was conducted. All observations and recommendations are in Section D. Summary of Findings/Comments of this inspection report. In the future, a sampling inspection for the whole effluent toxicity and chemistries will be performed at your facility and combined with this CEI report. The wastewater treatment plant appeared to be in compliance with the Town of Robbins NPDES permit. Please note that the housekeeping that was performed by the ORC was acceptable. However, the appearance of the grounds of the wastewater treatment plant was below average and not favorable. It was blemished by the accumulative collection of several items in disrepair: vehicles that included a fire truck, a street department truck, a Buick car, a Dodge Ram truck (that was the former wastewater treatment plant truck), a 2,000 gallon sludge hauling truck (that was the former wastewater treatment plant sludge hauling truck), a police car, a generator, a pump, a conventional bar screen, and stainless steel diffusers; and, there were rock piles, brush piles, and dirt piles located near the front gate. Please send a letter to this office by January 1, 2006, that explains the purpose of keeping the above listed items on the premises of the wastewater treatment plant, and please include a Plan -of -Action for the removal of the above mentioned items.

This is an endeavor we all take seriously and strive to perform. The 'issue -of the..mentioned items in.:your. November: 8; 2005:.1etteriwillrrequire some; ; c: explanation. First, upon original construction of the WWTP in 1966, this fenced in area was and still is, occupied by the WWTP (its equipment and personnel) and the Town of Robbins streetdepartment,: its equipment and personnel as well.. This area is the only fenced and protected property the Town of Robbins has. Second, upon the WWTP upgrade in 1998 with the addition of a 300,000 gallon aerobic digester, we had to relocate equipment throughoutthe compound as best we could. The mentioned brush pile was from debris pick-ups and has long since been gone. The rock and dirt piles are in a staging area and will be relocated to the further most corner, as well as the vehicles, that are occupied by thestreet department The normal storage area for these types of materials and equipment was in the area of the constructed aerobic digester and as you can see, we have limited area to secure and protect materials- and equipment. t� i�.i ! • + . , . ..
