Questions & Answers / Clarifications

This document provides responses to vendor questions regarding Solicitation 140P1426Q0031 for Groundwater Monitoring at Grand Teton National Park.

• Formaldehyde Analysis: Required only for the three Gros Ventre wells as listed in Table 3.
• Purge Water Disposal: For annual monitoring, purge water may be scattered on the environment. For Colter Bay Landfill monitoring, it can be disposed of at the Colter Bay Sewage System (43.901422°, -110.627404°). The COR will facilitate site access.
• Dedicated Bailers: No wells currently have dedicated bailers installed.
• Reporting Frequency: One report per year is required, inclusive of both spring and fall events. Spring sampling results should be provided when available, potentially in an Excel format similar to Attachment 6.
• IDW Disposal (Colter Bay Landfill): Liquid IDW and disposable sampling equipment can be disposed of at the Colter Bay Sewage System. The COR will facilitate access.
• IDW Disposal (Bi-annual Sampling): IDW for bi-annual sampling may be scattered on the environment, as background data does not suggest it is hazardous.
• Work Plan/HASP: A proposed methodology, including a work plan or Sampling and Analysis Plan, is required with the bid proposal, in addition to a Health and Safety Plan (HASP).
• Sampling Techniques: Standard sampling techniques, as described in the U.S. EPA manual RCRA Groundwater Monitoring Technical Enforcement Guidance Document (September 1986), are acceptable for all sites unless alternate methods are approved.
• Small Business Set-Aside: Confirmed as a small business set-aside with NAICS Code 541620 and a Small Business Size Standard of $19M.
• Recent Experience: Ongoing projects can be submitted if at least 50% complete.
• Laboratory Analysis: Included in the contractor's unit pricing.
• Report Format: Attached groundwater monitoring reports are representative of the expected format and detail for future reporting.

These clarifications provide specific details on waste disposal, sampling methods, reporting, and experience requirements. Offerors should ensure their proposals address these points. The solicitation is a small business set-aside under NAICS 541620.

Amendment / Modification

• Amendment 0001 to Solicitation #140P1426Q0031 clarifies that the requirement for "Annual Groundwater Sampling of Monitor Wells in Grand Teton National Park and the John D. Rockefeller Memorial Parkway" is a Total Small Business Set-Aside.

• This clarification corrects an error in the original solicitation (SF-18) which incorrectly stated that it was not a small business set-aside.

• The clarification pertains to the set-aside status of the requirement.

• This amendment does not appear to change the proposal deadlines or other submission requirements, but it is critical for small businesses to note the set-aside status for eligibility.
