About this file
This is a Questions and Answers document for a solicitation regarding the Rock Point Sheep Dip Vat project for the Department of Interior Bureau of Indian Affairs Navajo Region.
The document addresses contractor questions about a contaminated sheep dip vat (SDV) site that has not been used since before 1987 when toxaphene was banned across the Navajo Nation. Key details include an estimated 29.9 cubic yards of contaminated soil to be removed based on a 2003 survey, with contamination potentially exceeding 5 feet deep in sandy/gravelly soil. The work requires soil sampling, removal of contaminated soil, and backfilling with compacted material to prevent subsidence and ponding. The government notes that site visits are permitted but not compensated, and that extensions may be considered due to potential delays from external program offices.

There was a survey done in 2003, when was the SDV last used? The concrete structures look like they have been buried a by a couple of feet of sand.
Government response.
Last use of this particular SDV is unknown. Majority of the SDVs across the Navajo Nation have not been used in decades; most prior to the ban of toxaphene across the reservation in 1987. Whether the concrete structures are buried is unknown. Bidders are welcome to conduct a site visit without compensation from the government.
Is the area(s) need to be addressed it has sample boring up to 5' deep. If the contamination exceeds the RSL at 5' deep, will it need to be tested deeper? The soil in this area is sand and gravel so that contamination will likely be deeper than 5' in the heavily concentrated areas.
Government response.
Goal is to remove all contaminated soil based on sampling results.
Was there an estimate on how much material would need to be hauled off? This is very remote and getting heavy trucks to this site will be difficult.
Government response.
Last estimate was based on 2003 survey at 29.9 cubic yards of contaminated soil.
With the soil compaction for material brought in being greater than 90% is that a hard and fast? The type of native material will likely be less than 90% compaction, that would be equivalent to a road base type material being placed on a ridge in the middle of nowhere not needing stabilization.
Government response.
Not understanding “hard and fast?” Compaction is to prevent subsidence and ponding.
Can there be an extension for this solicitation if needed? Getting environmental information can take more time than other solicited materials.
Government Response.
Not understanding what kind of extension? Environmental? BEM is aware that an extension maybe requested due to the delays from external program offices.
