The State Environmental Commission adopted amendments to Nevada Admin. Code §445A, relating to hazardous waste, hazardous substances, and USTs. The rules authorize the 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 activity in determining whether to accept an action level for soil under certain circumstances; 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 regulated 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 certain corrective actions; and revise provisions governing releases from USTs. http://www.leg.state.nv.us/register/2008Register/R189-08A.pdf.
