Broad Agency Announcement Solicitation Amendment 0004

AMENDMENT 0004 - Summary of Changes
The following changes are incorporated into solicitation PHMSA-26HM-BAA via Amendment 0004:

1. PURPOSE OF AMENDMENT

The purpose of this Amendment 0004 is to incorporate additional responses to inquiries concerning the solicitation as a continuation of questions 14 through 18 under Amendment 0003.

2. QUESTIONS AND ANSWERS (Q&A)

Question 19: Indirect Rates
Inquiry: The cost table in the white-paper template lists fringe benefits (36.06%), labor overhead (50.62%) and general and administrative expense (35.80%). May I enter one fully burdened hourly rate for a single labor category, leave those three lines at zero, and state the rate basis in the narrative?

PHMSA Response: Yes.
Question 20: Estimated Cost
Inquiry: The cover page asks for Estimated Cost. In the cost table, line 13 is "Total Estimated Cost (Line 8 + Lines 9 to 11)" and line 16 is "Total Technical Effort". Which line should the cover page carry, and is a fee or profit line permitted?

PHMSA Response: Provide the largest total amount on the cover page. You are welcome to add lines to the cost. Question 21: Representations and Certifications
Inquiry: The attachment "Clauses and Contractual Requirements" opens its Section II ("Regulatory Provisions and Contract Clauses") with "Prior to the submission of a proposal, the Offeror must thoroughly review and complete the provisions detailed below." One of those provisions, FAR 52.240-90, has a representation that the offeror completes by marking WILL or WILL NOT, and a certification that begins "By signing this proposal." Does Section II apply to a Phase I white paper, or only to a Phase II proposal? PHMSA Response: This applies to a Phase II proposal.
Question 22: Which BAA File Governs
Inquiry: Amendment 0002, Question 3 says the November 18, 2026 (11:59 AM Eastern Time) deadline applies to Phase I white papers, and Amendment 0001 changed the submission address to [email protected]. SAM.gov also lists a file named "1- BAA Solicitation_PHMSA-26HM-BAA.docx", posted October 15 after Amendments 0002 and 0003, whose submission window and submission address still read December 22, 2026 and "PHMSA submission inbox". Please confirm that the amendments govern, so that a white paper is due November 18, 2026 and goes to [email protected].

PHMSA Response: The white papers are still due on November 18, 2026 and due to [email protected].
