  • Installation of a fish screen on any permanent water diversion or intake that is not already screened.

  • Projects that require in-water installation of hollow steel piling greater than 24 inches in diameter, or use of H-pile larger than designation HP24.

  • Drilling or sampling in an EPA-designated Superfund Site, a state-designated clean-up area, or the likely impact zone of a significant contaminant source, as identified by historical information or U. S. Army Corps of Engineer representative.


(5)  Site Restoration - Restore damaged streambanks to a natural slope, pattern, and profile suitable for establishment of permanent woody vegetation unless precluded by pre project conditions (for example: natural rock substrate):


  • Replant all damaged streambanks before the first April 15 following construction.

  • If use of large wood, native topsoil, or native channel material is required for the site restoration according to the roadside development plans, stockpile all large wood, native vegetation, weed-free topsoil, and native channel material displaced by construction. Cut trees or large wood and trees into pieces of no less than 20 feet in length, or as shown on the roadside development plans or as directed. Stockpiled native wood and vegetation remain the property of the Agency.

  • Stabilize all disturbed soils, including obliteration of temporary access roads, following any break in work unless construction will resume in 4 Calendar Days.


(6)  Surface Water Diversions - Surface water may be diverted to meet construction needs other than work area isolation, consistent with Oregon law, only if water from sources that are already developed, such as municipal supplies, small ponds, reservoirs, or tank trucks, is unavailable or inadequate, and meeting the following conditions:


  • When alternative surface sources are available, divert from the stream with the greatest flow.

  • Install, operate, and maintain a temporary fish screen.

  • Do not exceed a pumping rate and volume of 10% of the available flow. For streams with less than 5 cubic feet per second, do not exceed drafting of 18,000 gallons per day. Do not use more than one pump for each site.
