Clarifications – Questions and Answers Solicitation 140L6424Q0002 Herbicide Treatment to Shooting Ranges

1. Site visit to the prospective treatment sites.

Recreation Specialist Matt King (480-254-1655) will be available for site visits.

3. Work must start on or before September 1st, 2024 and be completed by March 29, 2025".

With the nature of the treatment POP would ideally start at award of contract. If conditions are not ideal for spraying due to environmental conditions we have until September 1st 2024 to start work. Work must be completed by March 29th, 2025.

4. Will there be any treatment in the exclusion areas, (RED), or only in the Facility areas, (BLUE)? Does the measurement of 626 acres include non-treatment areas. What is the actual treatment area measurement?

The 626 acres stated does include not-treatment areas. The only treatment within the red exclusion zone will be 5 feet off the hazardous exclusion zone fence.

5. Under Measurement and Payment of the SOW, it states, " Request for measurement must be made in writing within 10 days after seeding has been completed" Where is the seeding being done? Am I pretreating ground or treating after? Either way the seed will need a minimum of 4 months to establish or for chems to wear down. This is important for the type of chemical needed to get priced out.

There will be no seeding this was a missed typo and should have said "Treatment", corrected.

6. List of the BLM approved chemicals provided in Amendment #3. What has been used before or preferred?

The shooting sites are a first for chemical treatments of these types. Typically we cut stump treatments for Salt Cedar using triclopyr and Foliar treatments using glyphosate, triclopyr and Imazapyr. I have attached the Pesticide Use Plan for this project, which has the chemicals we plan on using. If there are any additional Chemicals outside these on the approved list, then we would need to add them (this could take up to a month to get approved and signed).

The first treatment of the sites was treated with Roundup Custom 524-343 and Garlon 4 Ultra 62719-527. List of approved herbicide, adjuvants, and fully executed PUP attached.

7. SOW states on pg #1 of General Requirements " Treatments will consist of foliar application of herbicide" and later on pg #2 under Description of work " the work shall be a foliar/pre-emergent chemical treatment" FYI: Foliar application is spraying over the tops of the canopy of established vegetation which can be a selective or non-selective herbicide, specific to woody/shrubby plants or total kill. A pre-emergent usually consists of treating the earth directly to reach the seed bank to stop growth at seed germination. Can you be more specific on the type of treatment required, could it be a bare-ground treatment applied early for the prevention of all unwanted vegetation.

This treatment will consist of a non-selective foliar application to invasive weeds and woody vegetation found within the shooting lanes, burms, and hazardous exclusion area fence 5' on both sides of the fence to prevent woody species degrading the fenceline.
