The Trenton City Council gave final approval to 2 actions taken last week by the Trenton Board of Public Works.
One of them is to hire the engineering and design firm Olsson Associates to determine whether it's feasible to upgrade TMU diesel power generators to meet environmental air protection agency standards for emissions. The cost of the study is not to exceed nearly $23,700.
The generators are used when Trenton is asked by a power pool to produce electricity for the pool. In exchange for having the generators available, Trenton receives credits on the power it purchases. The credits average around $150,000 a year.
It's anticipated the cost to upgrade the diesel generators to meet EPA standards could be recouped in less than 10 years by the credits Trenton receives for having those generators.
The Board of Public Works has budgeted $750,000 for the generator upgrades to meet the EPA air emission standards. However, the study by Olsson Associates is to provide a more exact cost for the upgrades and benefits of keeping the generators available for service.
The generators run about 25 hours a year on average for the power pool.
If the generators are not upgraded to meet EPA air emission standards, they still could be used to produce power in emergencies, but they would not qualify for the credits.
TMU purchases the power used in the City and resells it to its customers. The local generators are supposed to be able to produce electricity for the City when the incoming power from a grid is lost. However, TMU Director, Chad Davis, this morning told the City Council efforts are continuing to get that feature to work.
The Trenton City Council this morning also approved the engineering firm Burns and McDonnell to oversee efforts to determine infiltration and inflow sources in the sewer collection systems. It's in connection with governmental requirements at the Wastewater Treatment Plant area. The cost of the infiltration and inflow study is not to exceed $153,000. Burns and McDonnell is subcontracting with Trekk Design Group for part of the work.
The TMU Board of Public Works earlier this week approved the contract for the sewer system study.
The two votes by the City Council were unanimous among the 7 members attending. Jacob Black was absent.
