GPs are valid for five years and may be re-authorized by the Corps.
RGPs and PGPs may only be issued following the publishing of a public notice, and preparation of a decision document to ensure that the authorized activities cause only minimal individual and cumulative environmental impacts.
In the majority of cases, RGPs and PGPs contain conditions to further ensure that environmental impacts are minimal, including conditions for the submittal of a permit application prior to activities occurring within waters of the U.S. To ensure compliance with the RGP or PGP, you must carefully read all of the terms and conditions of an RGP or PGP prior to initiating construction activities in waters of the U.S.
