Broad Agency Announcement Solicitation Amendment 0002

Amendment 0002 - Summary of Changes

The following changes are incorporated into solicitation PHMSA-26HM-BAA via Amendment 0002:

1. PURPOSE OF AMENDMENT

The purpose of this Amendment 0002 is to incorporate PHMSA’s Responses to Vendor Inquiries regarding Phase I white paper submissions, subcontractor eligibility for foreign entities, submission limits, deadlines, and multi-topic proposals under Solicitation PHMSA-26HM-BAA.

2. QUESTIONS AND ANSWERS (Q&A)

Question 1: Foreign University Research Partner Eligibility Inquiry: Can a foreign university (e.g., based in the United Kingdom or other foreign country) participate as a research partner or subcontractor under PHMSA-26HM-BAA, and what specific restrictions or requirements apply?

PHMSA Response: Yes. Foreign universities are permitted to participate as research partners or subcontractors, provided the entity is not located within a comprehensively sanctioned country or region (pursuant to FAR Subpart 25.7, specifically 25.701(b)). Foreign entities cannot serve as the prime offeror; the prime offeror must be a U.S.-based entity. Proposals involving foreign subcontractors must clearly define the specific responsibilities, data access requirements, and technical contributions of the foreign entity. Question 2: Limits on Multiple White Paper Submissions
Inquiry: Is there any restriction or limit on the number of Phase I white papers that a single organization or Principal Investigator (PI) may submit across different research topic areas?

PHMSA Response: You may submit up to 5 distinct white papers per research group. Ensure each submission is standalone, fully compliant with the required templates and formatting (single file, up to 9 pages), and clearly indicates its applicable topic area in the email subject line. Submissions that span topic areas should still only be submitted under the single, most applicable topic area. Question 3: Phase I White Paper vs. Phase II Proposal Submission Deadlines Inquiry: Does the November 18, 2026 deadline apply to Phase I White Paper submissions, or must white papers be submitted earlier so full proposals can be requested by November 18?

PHMSA Response: The deadline of November 18, 2026 (11:59 AM Eastern Time) applies specifically to Phase I White Paper submissions. Following evaluation of Phase I white papers, selected offerors will be formally invited to submit Phase II Full Proposals. A separate submission deadline for Phase II proposals will be provided in the formal invitation letter.
