40 CFR § 271.4 - Consistency.
To obtain approval, a State program must be consistent with the Federal program and State programs applicable in other States and in particular must comply with the provisions below. For purposes of this section the phrase “State programs applicable in other States” refers only to those State hazardous waste programs which have received final authorization under this part.
(a) Any aspect of the State program which unreasonably restricts, impedes, or operates as a ban on the free movement across the State border of hazardous wastes from or to other States for treatment, storage, or disposal at facilities authorized to operate under the Federal or an approved State program shall be deemed inconsistent.
(b) Any aspect of State law or of the State program which has no basis in human health or environmental protection and which acts as a prohibition on the treatment, storage or disposal of hazardous waste in the State may be deemed inconsistent.
(c) If the state manifest system does not meet the requirements of this part, the state program shall be deemed inconsistent. The state manifest system must further allow the use and recognize the validity of electronic manifests as described in § 260.10 of this chapter.
