This action is an Administrative Order combined with a CWA 308(a) Request for Information to Terra Nova Development, LLC (owners) regarding umpermitted discharges of fill material associated with the Vistas Subdivision in Redding (Shasta County), CA. In 2003, Terra Nova undertook to develop a ridgeline development site known as The Vistas on steep slopes above Sulphur Creek in Redding. In the process of grading the site, approx 1acre of riparian wetland and approx 2 miles of intermittent tributaries were filled without a CWA 404 permit. Additionally, the work began immediately prior to winter storm events, and prior to the installation of adequate erosion control measures, which resulted in the sischarge of significant amounts of sediment from the site directly into Sulphur Creek. At one point, N&T Digmore, the earth-moving contractor, utilized mechanical pumps to accelerate these direct discharges in order to dewater the construction area. The State Regional Water Quality Control Board has issued an Administrative Civil Liability fine to Terra Nova of $85,000 for stormwater general permit violations. This AO requires respondents to stabilize the site, by employing an erosion control specialist, in anticipation of the 2004 wet season. Also, Terra Nova must produce a plan and schedule for any further work as well as proposed mitigation. Ultimately, we anticipate negotiating an AOC with Terra Nova, N&T Digmore, and Whitson Engineering for injunctive relief, including
