Per your request, I talked with Darhyl Boone from the Town of
Mars Hill about the stage of WTP construction. He stated that
the site had been graded for installation of the tank and the
backwash pond. They are laying the water lines and digging the
wet well now. They are also doing work on the storage tank in
preparation for pouring the slab. They should have all the
concrete work finished by December ('96). The plant should be
on-line by the Spring ('97).
The ARO recommends renewal of the NPDES permit as proposed.
