Heading: Storm Water Run-Off and Treatment System

Text: The Town argues that the record does not support DES's decision to grant a 100% exemption for the Plant's storm water run-off and treatment system. We disagree. In Appeal of Town of Newington, 149 N.H. at 351, 821 A.2d 1100, we upheld a DES decision to grant a 100% exemption to a storm water management system. We noted that testimony in the record stated that the system was designed to minimize erosion, stabilize embankments, and control runoff, as well as to trap sediment to prevent silt-laden runoff water from entering sensitive environmental areas. Id. The Application here similarly asserts that the system is designed to prevent local flooding of the site area in a controlled manner to prevent erosion, and that [the system] is necessary to treat yard run-off to remove sediment before discharge from the site. The Application also provides a schematic drawing of the system and cites available supporting documents. Accordingly, DES's decision to grant an exemption to this system was amply supported by the record and we decline to overturn it.
