Hazardous Site or Trespass Data Standard Version 3.0

This information bulletin announces the availability of and describes the recent updates to the Hazardous Site or Trespass Data Standard Data Standard Version 3.

The Hazardous Site or Trespass (HAZ_TRES) dataset represents spatial location and basic information about hazardous or potentially hazardous sites, or trespass or potential trespass sites. Hazards might be physical or environmental. The sites might be prior authorized development such as abandoned mine lands. Trespass is defined as unauthorized use, occupancy or development other than casual use, upon public lands without a prior land use authorization or a right granted by statute or law, that causes physical damage to public lands, property located thereon or resources or loss of revenue to the United States.

This dataset is used to display hazardous areas or trespass sites on maps for field verification and briefings. The spatial features can be combined with other spatial datasets to assess impact to resources and for reporting purposes. There are reporting requirements to regulatory agencies such as the U.S. Environmental Protection Agency and Oregon Department of Environmental Quality as well as BLM "Environmental Disposal Liabilities" reports to the US Department of the Interior.
