The contractor will not be liable for not seeding any remaining hole in the work area and any unused seed shall be turned over to

USFWS at the conclusion of the project. The grass shall be seeded as described above in Task 2.0

*In the event species specified below are not available, USFWS must approve substitutions and or changes in composition.

o Task 2.2: Turf Grass Planting at West Location

• A turf grass seed mix as specified below must be seeded in two 6 ft swaths bordering the sidewalk noted on the attached map. The sidewalk is not installed yet but a corridor marking the sidewalk will be flagged off on site prior to seeding. The contractor shall seed 6 ft from each flag with the turf grass seed mix. A turf grass seed mix as specified below will also be seeded in one 6 ft swath immediately bordering the western and southern fenceline. The seeding shall be at a rate of 43 PLS lbs. per acre.

*In the event species specified below are not available, USFWS must approve substitutions and or changes in composition.

7.1 If using a no till seed drill the following quality control measures are required.

If using a hydro seeder, brillion or other seeding method the following quality control measures are required.

Quality Control USFWS Contractor Seed is stratified and of an appropriate ecoregion for germination at Altus AFB.

Seed hopper is checked routinely to ensure it is fi l led to level recommened by dril l manufacturer.

Seeder is operated such that tubes do not become plugged.

Seeder is operated such that picker wheels turn appropriately.

Tractor and seeder are operated at the speed set by manufacturer for seeding rates.

Rows are checked during seeding for the appropriate seeding depth and to ensure seed is sown in the manner specified by the dril l seeder manufacturer.

USFWS biologist is on site during seeding to ensure the above specifications are met and to advise if corrective action is needed for no less than 90% of the seeding.

Quality Control USFWS Contractor

Seed is stratified and of an appropriate ecoregion for germination at Altus

AFB.

Equipment is operated such that seed is not suspended deeper than 1/4 in matrix or soil

Adequate coverage is achieved over area of site
