Preassessment Screen Clause Samples

Preassessment Screen. Readily available data is reviewed to determine whether a release justifies an NRDA. Five questions must be answered affirmatively to proceed with an NRDA:  Has a discharge of oil or a release of a hazardous substance occurred?  Have natural resources for which the federal or state agency or tribe may assert trustee- ship under CERCLA been, or are they likely to be, adversely affected by the discharge or release?  Is the quantity and concentration of the discharged oil or released hazardous substance sufficient to potentially cause injury to those natural resources?  Is data sufficient to pursue an assessment readily available or likely to be obtained at reasonable cost?  Will response actions, if any, not sufficiently remedy the injury to natural resources with- out further action?
