1. (1) Description: The department applies timing windows to reduce the risk of impacts to fish life at sensitive life stages. In-water work is not allowed during critical periods of the year unless a person can take mitigation measures to eliminate risk during critical periods.
2. (2) Fish life concerns: Work in or near salt waters of the state can harm fish life at sensitive life stages including spawning, incubation, juvenile migration, rearing, and feeding. Therefore, work must occur at times of the year when the risk to fish life is reduced unless the risk can be avoided.

3. (3) Authorized work times: The department must specify authorized work times for hydraulic projects when it issues HPAs. The department will allow work waterward of the OHWL for the following times, areas, and species.

   1. (a) Tidal Reference Areas 1 through 17; March 1 through October 15 for projects in or adjacent to documented Pacific sand lance spawning beds.
   2. (b) Tidal Reference Areas 1 through 17; October 15 through May 15 for projects in or adjacent to juvenile lingcod settlement and nursery areas. April 1 through December 31 for projects in or adjacent to lingcod nests.
   3. (c) Tidal Reference Areas 1 through 17; September 30 through March 15 for projects in or adjacent to juvenile rockfish settlement and nursery areas.
   4. (d) Tidal Reference Area 14; October 1 through May 15 for projects in or adjacent to documented razor clam beds.

   5. (e) Tidal Reference Areas 1 through 17; the authorized times and areas for protection of migrating juvenile salmonids in the nearshore, and for projects in documented Pacific herring spawning beds and in or adjacent to documented surf smelt are listed in the following table:

   6. (f) If the surf smelt spawning season for the project location is six months or longer, the department may permit work outside of the authorized work times if:

      1. (i) A department-trained biologist, following the department's intertidal forage fish spawning habitat survey protocol per WAC 220-660-340, conducts a spawning survey at the job site;
      2. (ii) The results of the inspection show that no spawning is occurring or has recently occurred; and
      3. (iii) If the survey shows eggs are not present, the person may start work. The person must start work within seventy-two hours of a survey.
   7. (g) In documented intertidal forage fish spawning areas, the department must not allow work during surf smelt spawning seasons shorter than six months or during the Pacific sand lance spawning season. The department will make exceptions for projects receiving emergency, imminent danger, and expedited HPAs.
   8. (h) The department will require an intertidal forage fish spawning bed survey if the job site is adjacent to a documented forage fish spawning bed, the beach at the job site has bed materials similar to the documented beach, and the work will occur during the spawning season.
   9. (i) When specifying authorized work times for hydraulic projects, the department must consider the construction techniques, mitigation measures proposed, location of the project, and characteristics of habitats potentially affected by the project. The department may inspect the work area to evaluate the habitat.
   10. (j) During times when work in waters of the state is prohibited to protect nearshore juvenile salmonid migration, rearing, and feeding areas, the department may permit construction if the structure is located at or landward of the OHWL, and if all construction work is conducted from the landward side of the project.
   11. (k) The department may apply additional timing restrictions to protect other important habitat that supports fish life at a specific site.
