(a) Requirement.--An environmental covenant, any amendment or termination of the environmental covenant and a waiver under section 6510(a)(3)(i) or (b)(2) (relating to amendment or termination by consent) must be recorded in every county in which any portion of the real property subject to the environmental covenant is located. A recorded environmental covenant or a notice recorded under section 6512 (relating to registry; substitute notice) must be indexed in the grantor's index in the names of the owners of the real property subject to the environmental covenant and in the grantee's index in the name of the holder.(b) Applicable law.--Except as otherwise provided in section 6509(c) (relating to duration), an environmental covenant is subject to the laws of this Commonwealth governing recording and priority of interests in real property. Recording of an environmental covenant pursuant to the laws of this Commonwealth provides the same constructive notice of the environmental covenant as the recording of a deed provides of an interest in real property. 2007, Dec. 18, P.L. 450, No. 68, § 1, effective in 60 days [2/19/2008].
