Answer: No

2. Question: How many feet from the edge of the spillway is the vendor required to spray?

Answer: The vendor must spray approximately 6-10' from the edge of the spillway or up to the edge of the rock wall adjacent to the spillway. Access from the top of the spillway is easiest.

3. Question: What is the lead time the government will provide the vendor when calling in for summer treatments?

Answer: See section 3.3 of the Performance Work Statement. The government will call the vendor to request summer treatments and allow 10-days to two-week lead time for the contractor to provide the treatment.

4. Question: How long does the government anticipate it will take for the vendor to complete each summer spray treatment, and what are the target species?

Answer: The amount of time for the vendor to complete each application will depend on the equipment used and manpower allocated to the work. The primary species are kochia and invasive thistles. Navajo Dam personnel estimate 2 summer spray treatments, depending on precipitation received during the summer.

Answer: Target areas for algae treatment are along the ditches and seepage waterways. This does not include any of the San Juan River.
