The rock rip rap placed in the bottom of the SAFETY•SCIENCE <br /> excavated spillways was sufficient in size and volume to deter erosion. No erosion of thg <br /> I BI Owens <br /> embankment cut slopes was observed. The severe scarification and the minimal height OL se <br /> areas was sufficient to minimize erosion potential. The silt fence erected at the base of eacia"ke <br /> slope was removed in 2003, as the vegetation appears sufficient to prevent sediment geAMtT6$'.rector <br /> No erosion or sediment generation problems were noted at any of the discrete pond locaW. .�ttany <br /> Ivlslon Director <br /> is apparent that the vegetative cover has become sufficiently established to warrant a regimEA&rurce Trustee <br /> permit termination. <br /> B. Comprehensive inspections of the pond construction areas were made on a periodic basis <br /> from June through October 2005.
