With no explanation, chose the best option from "A", "B", "C" or "D". the regula tion provides that electronic devices and components are not waste so long as they can be “resold,” “donated,” “repaired,” “refurbished,” or “reuse[d].” Part 273.2(f)(3). The defendants have offered one permissible reading of the regulation. They argue that Part 273.2(f)(3) does not expressly include an original intended purpose requirement, and that the words “resold,” “donated,” “refurbished,” and “reused” likewise do not mandate such a requirement. Thus, they interpret Part 273.2(f)(3) to mean that an electronic device or component that can be resold, donated, repaired, refurbished, or reused for any purpose is not waste. Although the defendants’ reading of the regulation may be permissible, the regulation can also be reasonably interpreted to include 42 (Colo.App.1997) (<HOLDING>).
