(a) cause or significantly contribute to an increase in mortality or an increase in serious irreversible or incapacitating reversible illness; or

(b) pose a substantial present or potential hazard to human health or the environment when improperly treated, stored, transported, or disposed of or otherwise managed.

(6) "President" means the president of the United States.

(7) "Release" means any spilling, leaking, pumping, pouring, emitting, emptying, discharging, injecting, escaping, leaching, dumping, or disposing into the environment but excludes:

(d) the normal application of fertilizer.

(8) (a) "Remedial action" means those actions consistent with a permanent remedy taken instead of or in addition to removal actions in the event of a release or threatened release of a hazardous substance into the environment that prevent or minimize the release of hazardous substances so that they do not migrate to cause substantial danger to the present or future public health or welfare or the environment. The term includes but is not limited to those actions at the location of the release as storage; confinement; perimeter protection using dikes, trenches, or ditches; clay cover; neutralization; cleanup of released hazardous substances or contaminated materials; recycling or reuse; diversion; destruction; segregation of reactive wastes; dredging or excavations; repair or replacement of leaking containers; collection of leachate and runoff; onsite treatment or incineration; provision of alternative water supplies; and any monitoring reasonably required to ensure that the actions protect the public health and welfare and the environment. The term includes the costs of permanent relocation of residents and businesses and community facilities if the president determines that, alone or in combination with other measures, the relocation is more cost-effective than and environmentally preferable to the transportation, storage, treatment, destruction, or secure disposition offsite of hazardous substances or is otherwise necessary to protect the public health or welfare.

(b) The term does not include offsite transport of hazardous substances or the storage, treatment, destruction, or secure disposition offsite of the hazardous substances or contaminated materials unless the president determines that the actions:

(i) are more cost-effective than other remedial actions;

(ii) will create a new capacity to manage, in compliance with subtitle C of the federal Solid Waste Disposal Act, hazardous substances in addition to those located at the affected facility; or

(iii) are necessary to protect public health or welfare or the environment from a present or potential risk that may be created by further exposure to the continued presence of the substances or materials.
