I would like to thank Emerald for your assistance with the recent equipment recycling effort... We have disposed of three power transformers and thousands of gallons of oil...I also want to express my appreciation for your field service crew. The crew has been on property the last two weeks removing transformers from substations. The work was completed in a safe, timely and professional manner. Your crews have been on property for prior recycling efforts and I am always pleased with their efforts. I look forward to working with you to remove the remainder of the equipment by the end of the year.
