This amendment is required to provide and install stainless steel liner panels with polysulfide sealant at thirteen roof access hatches and/or roof scuttles. Four of the hatches are located on the Sludge Bio-Filter Building roof, five hatches are on the Southwest Coarse Screen Bio-Filter Building roof, and the remaining four hatches are located on the Post-Centrifuge Bio-Filter Building roof. The stainless steel liner panels and corresponding polysulfide sealant are required to isolate the roofing assembly and roof curbs from the hazardous environment associated with the bio-filter process.
