1. (1) If a municipal solid waste landfill is subject to 40 CFR, Part 258 as provided in 40 CFR, §258.1, the owner or operator shall comply with landfill location restrictions in 40 CFR, Part 258, Subpart B. Except as otherwise provided in OAR 340, division 94, any person who designs, constructs, maintains, or operates any municipal solid waste landfill must do so in conformance with the location requirements of this rule.
2. (2) Floodplains. No person shall establish, expand or modify a landfill in a floodplain in a manner that will allow the facility to restrict the flow of the base flood, reduce the temporary water storage capacity of the floodplain, or result in washout of solid waste so as to pose a hazard to human life, wildlife or land or water resources.

3. (3) Endangered Species. In addition to the requirements of 40 CFR, Part 258, Subpart B, no person shall establish, expand or modify a landfill in a manner that will cause or contribute to the actual or attempted:

   1. (a) Harassing, harming, pursuing, hunting, wounding, killing, trapping, capturing or collecting of any endangered or threatened species of plants, fish, or wildlife;
   2. (b) Direct or indirect alteration of critical habitat which appreciably diminishes the likelihood of the survival and recovery of endangered or threatened species using that habitat.

4. (4) Sensitive Hydrogeological Environments. In addition to the requirements of 40 CFR, Part 258, Subpart B, no person shall establish or expand a landfill in a gravel pit excavated into or above a water table aquifer or other sensitive or sole source aquifer, or in a wellhead protection area, where the Department has determined that:

   1. (a) Groundwater must be protected from pollution because it has existing or potential beneficial uses (OAR 340-040-0020); and
   2. (b) Existing natural protection is insufficient or inadequate to minimize the risk of polluting groundwater.
