I haven’t been following this case, but here is an EPA release on penalties for wetlands violations.
The original enforcement action was filed against Rapanos in 1994 and the case drew national attention after the District Court ruling was appealed to the U.S. Supreme Court and subsequently sent back to the U.S. District Court for further proceedings. Rapanos challenged EPA’s findings that the filled wetlands were under federal jurisdiction under the Clean Water Act. The litigation determined that Rapanos did fill wetlands under federal jurisdiction.
In the late 1980s and early 1990s, Rapanos attempted to level three different parcels of land by uprooting vegetation and filling low spots with sand and dirt. He also dug an extensive network of ditches to dry out the sites, which resulted in excavated dirt being sidecast into wetlands. The parcels of land were intended to be developed for a shopping mall and residential homes.
There is a parallel criminal matter that is still pending and is not affected by the settlement under the agreement. The proposed consent decree, lodged in the U.S. District Court in Detroit, is subject to a 30-day comment period and final court approval. A copy of the proposed consent decree is available on the Justice Department Web site at www.usdoj.gov/enrd/Consent_Decrees.html.
