City of Charleston makes trucks greener

CHARLESTON, SC (WCSC) - The City of Charleston completed the DERA project which served to retrofit 19 existing medium and heavy duty City trucks with either Diesel Oxidation Catalyst (DOCs) devices or Diesel Particulate Filters (DPFs).  The project cost $129,700 and was funded by a Diesel Emissions Reduction Act (DERA) grant.  The DERA grant required the use of U.S. Environmental Protection Agency (EPA) approved verified technology.  Both DOCs and DPFs are authorized by EPA's verified technology list.

The EPA believes that diesel exhaust poses one of the greatest public health risks of all air pollutants.  Installation of these components reduces the release of harmful emissions.  The reduction of emissions translates into fewer heath problems attributed to the released particulates.  DOCs use catalytic reactions to convert pollutants to water and carbon dioxide.  A DOC can potentially reduce particulate matter by 20%, hydrocarbons by 50%, and carbon dioxide by 40%.  DPFs have the potential of reducing particulate matter, hydrocarbons, and carbon monoxide by 90%.

Fleet Management staff began ordering equipment on April 14, 2010 and the first DOC installation was completed by City of Charleston technician on April 28, 2010.  During the course of the project 13 dump trucks were retrofitted with DOCs and 6 rear-loader garbage trucks were fitted with DPFs.  Installations were complete on all 19 trucks by August, 26, 2010.
