The State Environmental Commission adopted amendments to NAC 445A, various provisions relating to pollution. The changes authorize the State Department of Conservation and Natural Resources to require an owner or operator of a facility to carry out a plan for additional characterization of a contaminated site; authorize the Director of the Department to consider certain activities in determining whether to accept an action level for soil; revise the requirements for conducting an assessment of a contaminated site; revise the immediate actions that an owner or operator must take upon the release of a hazardous substance, hazardous waste, or a regulation substance; authorize an action level for soil to be based upon a study approved by the Division under certain circumstances; revise the circumstances under which the Director may grant an exemption from corrective actions; and revise provisions governing releases from USTs. http://www.leg.state.nv.us/register/2008Register/R189-08RP1.pdf.
