(a) An environmental covenant and any amendment or termination of the covenant must be recorded in every county in which any portion of the real property subject to the covenant is located. A recorded environmental covenant or a notice recorded pursuant to § 7914 of this title must be indexed in the grantor's index in the names of the owners of the real property subject to the covenant and in the grantee's index in the name of the holder.(b) Except as otherwise provided in § 7908(c) of this title, an environmental covenant is subject to the laws of this state governing recording and priority of interests in real property. Recording of a covenant pursuant to the law of this state provides the same constructive notice of the covenant as the recording of a deed provides of an interest in real property. 75 Del.
