The Uniform Environmental Covenants Act (UECA) generally requires the use of environmental covenants (ECs) when engineering or institutional controls are necessary
to demonstrate attainment or assure maintenance of an Act 2 remediation standard. DEP is obligated under UECA to maintain a registry for the public display of covenants
received. Therefore, DEP has developed the Pennsylvania Activity and Use Limitation (PA AUL) Registry.
