The Massachusetts Maritime Academy has received a pledge from Clean Harbors Environmental Services, Inc. of Norwell, Mass. in the amount of $1.5m for naming rights to its contiguous athletic stadium and gymnasium complex. The acceptance of the pledge, which was presented by Clean Harbors Chairman and Chief Executive Officer Alan S. McKim, was approved unanimously earlier this morning by the school's Board of Trustees and announced by Admiral Richard G. Gurnon, President of the Massachusetts Maritime Academy. The Clean Harbors Athletic Center will be comprised of the athletic stadium, which is the current home of Commander Edward A. Ellis Field, as well as all athletic and recreation facilities currently housed in Alumni Gymnasium.
