Specifications include, but are not limited to: 5.2.1The cooling towers are cleaned out during the colder months from November through March to remove the sludge that has accumulated in them. The cooling towers arelocated at the main Central Plant, East Chill Plant, West Chill Plant, South Plant and Southeast (Jowers) Plant and Round Rock CUB in Round Rock campus. The City of San Marcos allows the water in the cooling towers to be discharged to the sanitary sewer, but not the sludge. Analysis of the sludge for metals and organics in May 2020 showed that it is a non-hazardous waste stream. The estimated volumes of sludge for the following plants are: •Central: 11,000 gallons•East Chill Plant: 1,500 to 2,800 gallons•West Plant: 500 to 750 gallons•South Plant: 1,600 gallons•Southeast (Jowers) Plant: 1,500 to 2,800 gallons•Round Rock CUB: 1,500 to 2,800 gallons5.2.2The scope of work includes removal and disposal of the sludge as non-hazardous. The work at Central, West, and South Plants are considered confined space because thework occurs down in the towers and there is one way in and one way out. There is plenty of fresh air in all locations and the workers do not need to wear air tanks. For scheduling, the Respondent will have to work with the University’s Supervisor in charge of the particular area. Cooling Towers are to be scheduled with the Plant Mechanic Supervisor. The Central Plant cooling towers should be cleaned out in one day and the West, South, East, Southeast (Jowers), and Round Rock CUB Chill Plants should be cleaned out on the second and third days. This will allow the University to bring the cooling towers back online as quickly as possible.Oil Water Separators at Facility (Physical Plant) Garage5.2.3There are two separator units at the Facility Garage. One is a grit chamber located in the Wash Bay and is approximately 500 gallons in size. The second separator is located in front of the garage and is also approximately 500 gallons. Access to both separators is good. This scope includes pumping the oil/water and solids from these two units and disposing of it at a permitted facility.
