Indian Reservations are lands set aside or reserved by the U.S. for the benefit of the a Tribe and are designed to provide all the necessary sustenance for the subject Tribe at the time the lands were reserved and in perpetuity. This means that the Tribe has the right to resources that are safe for traditional uses even though these lands cannot support these uses today, due to past inappropriate management practices. AESE, Inc. Since human health risk for those living close to the land are driven by traditional consumption rates occurring during traditional activities, Traditional, pre- contamination consumptions rates are employed to calculate how clean the resources must be. It is our experience working with tribes on superfund issues throughout the U.S., that because tribes rely heavily on natural resources, in many instances, their sole source of sustenance, these resources have to be free of site contamination. AESE, Inc. Since CERCLA cannot require a PRP to cleanup to conditions that are cleaner than pre-contaminated conditions, this means that Cleanups must focus on pre- contaminated conditions and not excess risk. In Summary, drawing this conclusion early in the process enables the focus of work to shift from estimating risk and back-calculating PRG/RAOs, to determining pre- contamination baseline and mapping the nature and extent of contamination. This early realization will result in saving large sums of time and money, makes EPA to appear more credible to the public, speeds the cleanup process while not costing the responsible parties additional sums, and more rapidly brings closure to the RI/FS and NRDA processes. AESE, Inc. The National Contingency Plan (NCP) prescribes the approach for selecting a CERCLA remedy. 40 CFR § 300.430. All alternatives considered by EPA, except 42 U.S.C. § 9601, et seq.

It lies ~800 feet off shore of the Sulphur Bank Rancheria, present-day home to the Elem Indian Colony. The island contains 6 recorded archaeological sites ranging in age from ~5,000 years old to the recent historic period. The largest of the 6 recorded sites is CA-LAK-89/H, which represents the ethno-historic village of Elem. All 6 sites contain prehistoric artifacts and features and many contain historic materials that represent the Mexican period (1834-1849), Overseas Chinese period (1850-1900), and recent historical events that have shaped the Elem people. Rattlesnake Island is recognized by the Elem Community of Southeastern Pomo as their place of origin as well as their political and religious center. At the time of the most recent archaeological and historical inspection (1978-81) the cultural sites on the island retained integrity with many original rock alignments and house depressions noted. Rock and brick foundations were found with associated historic cultural materials. The fact that the district is located on an island, coupled with its close proximity to the contemporary mainland location of the Elem Indian Colony have served Looking east at Rattlesnake Island, present Elem to protect the cultural resources it community is on mainland closest to the island.

  • Human Influences to Clear Lake, California a 20 Century History
    Human Influences to Clear Lake, California A 20th Century History Gregory A. Giusti University of California Cooperative Extension March 2009 1 Human Influences to Clear Lake, California - A 20th Century History Clear Lake is a large shallow, eutrophic (nutrient heavy), polymictic (well mixed) lake in the central Coast Range of northern California. Clear Lake is one of California’s oldest lakes and the largest natural lake (177 km2) existing entirely within California. It is also believed to be the oldest natural lake in North America, with continuous lake sediments dating to the early Pleistocene, yielding age estimates of 1.8–3.0 million years old. As part of a larger effort to collect and document biological and other pertinent information for this unique Lake, it’s important to document how 20th century human activity has affected present day Clear Lake. The intent of this paper is not to pass judgment on bygone decisions but to simply provide a history of these actions in context with the many current discussions that deal with water, invasive species and lakebed management. PEOPLE OF THE LAKE The Clear Lake basin is home to one of the oldest documented North American ‘‘early man’’ sites with paleo-Indian occupation going back almost 10,000 years. While the area was occupied by Native Americans since their initial settlement, the Lake, shoreline, and watershed have undergone extensive modification since European settlement in the mid-1800s (Fig. 1). Having lost an estimated 85% of its original natural wetlands, Clear Lake’s nutrient balance (nitrogen and phosphorus cycling) has been dramatically altered, resulting in frequent blue-green (cyanobacterial) algal blooms.
