WHEREAS,a Unit No.7 boiler tube study conducted by M&M Engineering Associates,Inc.,
in 2014,determined that the boiler tubes in the vicinity of the Power Plant's furnace displayed severe
thinning; and,
WHEREAS,the degradation of these tubes has resulted in an increase in tube repairs required
on the Unit No. 7 boiler to maintain operation; in addition to resolving the tube thinning issue,this
contract will call for the redesign of the lower tube sections to allow for better combustion of refuse
derived fuel (RDF); and,
WHEREAS,historically Unit No. 7 boiler has not combusted RDF as efficiently as the Unit
No. 8 boiler,and this has led to"unburned"amounts of RDF,which has caused plugs in plant piping

services to address these issues, and the selected firm will be required to supply certified technical
specifications and detailed cost estimates for the replacement of Unit No. 7 superheater,redesign of

firm; and,
