Synopsis: Preventative Maintenance Contract for the AWBERC WR2 Effluent Decontamination System
The U.S. EPA, Office of Research and Development (ORD), Safety, Health, and Environment Management Program (SHEM) located in Cincinnati, OH has a requirement for a multi-year comprehensive service program for the performance of preventative maintenance and unscheduled repair of the WR2 Effluent Decontamination System (wastewater sterilizer, serial number 031006) located in the subbasement of the Andrew W. Breidenbach Environmental Research Center. The EPA intends to negotiate on a sole source basis, under the authority of FAR 13.106-1(b)(i) with Biosafe Engineering for the maintenance of this system. NAICS Code 562211, Hazardous Waste Treatment and Disposal, applies to this procurement and the size standard is $47.0M. This procurement consists of maintaining the WR2 Effluent Decontamination System according to factory specifications and to ensure that the instrument meets or exceeds the State of Ohio biohazardous waste regulations. This includes all labor and travel costs.
The EPA requires two (2) preventive maintenance inspections during a twelve-month period. The contractor shall provide a warranty on all parts installed at the end of this contract. Such warranty on parts shall be effective for a minimum of ninety (90) days following installation of such parts on covered equipment. Specifics of the coverage on this agreement include but are not limited to the following:
a) Certification that all thermocouples are each accurately calibrated against a NIST traceable standard.
b) The pressure sensor is to be checked and tested for accuracy.
c) The HEPA filter on the unit is to be replaced during one of the two preventative maintenance inspections.
d) During the first preventive maintenance inspection and after decontamination, the unit is to be opened and checked for corrosion, scale formation and/or wear. As a preventative measure, descaling of the interior, heating coil, and cooling coil is to occur and will involve the following:
i) The Contractor shall supply dry citric acid flake (150 kg or more) along with the proper drums, supply pumps, and hoses needed for injection.
ii) Using the dry citric acid crystals, a 5-10% aqueous citric acid will be prepared and injected into the empty vessel.
iii) After injection of the citric acid solution, the WR2 Effluent Decontamination System will be either heated or run through a complete cycle.
iv) After the cycle is completed and the instrument has cooled, the manway door will be opened, and the efficacy of the descaling procedure will be evaluated. If the Project Officer determines on inspection that excessive residual scale remains on the heating and cooling coils, then this descaling procedure will be repeated during the second preventive maintenance inspection.
v) After the descaling treatment, the drums, pump, delivery hose, and other equipment will be disconnected and returned to the Contractor and will not be stored at the AWBERC U.S. EPA site.
vi) The acid injection port will be isolated, so the unit will run normally.
e) The Man-way gasket is to be replaced and checked for leakage after installation.
f) Lubricate and check the torque on the Man-way bolts.
g) The control panel is to be inspected for proper operation.
h) The PLC/controllers are to be inspected for proper operation and overhauled or replaced if necessary.
i) The remote diagnostic capability using the remote interface installed in 2019 shall be tested/verified.
j) All solenoid valves are to be checked for proper operation.
k) All ball valves and actuators are to be inspected and rebuilt if necessary.

l) The unit is to be checked for leaks.
m) The dry well used for spore testing is to be examined and the lid gasket checked for integrity. The gasket is to be replaced if it shows signs of wear.
