Line 1 & 2, Mandatory BPN Index Date and Location: To ensure an equitable evaluation baseline, all offerors use the BPN Weekly Propane Newsletter published on shall

, for the posting. The Thursday, April 23, 2026 AePEX Energy: Las Vegas, NV Government has pre-filled this information on the revised Attachment 2.

Line 3, BPN Index Price: The offeror shall enter the corresponding price per gallon for the AePEX Energy: Las Vegas, NV posting from the mandatory April 23, 2026 publication.

This price will serve as the "BPN Index Rate" for all calculations in Section B.

Line 4, Proof of Index Price: Because the Government does not maintain a BPN subscription, the offeror shall submit verifiable proof of the April 23, 2026, AePEX Energy:

Las Vegas, NV BPN index price as an attachment to Volume III. Acceptable proof includes an authorized excerpt from the BPN newsletter, a screenshot of the pricing table, or a certified pricing letter from the offeror's bulk supplier confirming the published BPN rate for that specific date and hub. Failure to provide proof of the baseline index price will result in the quote being determined unacceptable.

c. Instructions for Section B: Pricing Calculation Schedule

The "Estimated Annual Gallons" for each CLIN are provided by the Government and shall not be altered.

The "BPN Index Rate" column will be populated with the value the offeror enters in Section A, Line 3.

Offeror's Markup per Gallon: The offeror shall enter their firm-fixed-price, fully burdened markup per gallon. This markup shall remain fixed for the entire life of the contract, including all option periods. The markup must include, but is not limited to, all costs for transportation, freight, labor, tank provision and maintenance, administrative overhead, general and administrative (G&A) expenses, profit, etc.

The offeror shall propose a markup for the Base Year and for each of the four (4) Option Years.

Option to Extend Services (CLINs 5001/5002): The offeror shall not enter a new markup for these lines. These CLINs will be priced and evaluated using the markup proposed for Option Year 4, in accordance with FAR 52.217-8.

d. Instructions for Section C: Phase-In / Phase-Out Pricing

The offeror shall enter a single, total firm-fixed-price for CLIN 0003, Phase-In Activities.

The offeror shall enter a single, total firm-fixed-price for CLIN 4003, Phase-Out Activities.

Addendum to Evaluation - Commercial Product and Commercial Services

Miscellaneous text in this section has been modified to:

GENERAL

The Government will issue a purchase order to the responsible offeror whose quote conforms to this Request for Quote (RFQ) and is determined to be the most advantageous to the Government.

Award will be made based on the lowest evaluated price from among quotes that are rated "Acceptable" for the non-price factors.

EVALUATION PROCESS

The Government will use the following sequential process:

1. Responsibility Determination (Past Performance Gate):

The Government will first evaluate Volume II - Past Performance to determine if the offeror meets the (i.e., the definitive responsibility Special Standard of Responsibility criterion) outlined in the Addendum to FAR 52.212-1, Paragraph 2. Any offeror failing to meet this minimum requirement will be determined nonresponsible and their quote will be ineligible for award.

2. Technical Evaluation:

For all responsible offerors, the Government will evaluate the Technical Quote (Volume I). To be considered for award, the quote must receive a rating of "Acceptable."

3. Award Decision:

From the pool of quotes determined to be responsible and technically acceptable, an award will be made to the offeror who submitted the quote with the lowest total evaluated price.

EVALUATION FACTORS

1. FACTOR 1: PAST PERFORMANCE (Responsibility Determination)

The Government will evaluate the offeror's submitted past performance to verify that they meet the minimum requirement of at least one recent (active within the last 3 years) and relevant (similar scope and magnitude, defined as delivering 500,000+ gallons of propane annually) contract. The quality of this past performance will also be considered as part of the overall responsibility determination. An offeror that does not meet the minimum requirement will not proceed to the next stage of the evaluation.

2. FACTOR 2: TECHNICAL (Acceptable / Unacceptable)

For offerors who meet the past performance standard, the Government will evaluate their technical quote to ensure the proposed Technical Approach, Quality Control Plan (QCP), and Phase-In/Phase-Out (PIPO) Plan meet the minimum requirements of the PWS. The evaluation of the PIPO plan will specifically assess the offeror's ability to meet the required 30-day phase-in timeframe. A quote that fails to demonstrate a clear and adequate approach to meeting all PWS requirements will be rated "Unacceptable".

3. FACTOR 3: PRICE

Price will not be rated or scored. After identifying all responsible and technically acceptable quotes, the Government will determine the lowest-priced offeror based on the total evaluated price. The price evaluation will consist of the following:

Total Evaluated Price: The Government will calculate a total evaluated price for each quote.

This price will be the sum of all CLINs for the base period, all four (4) option years, the Phase- In/Phase-Out (PIPO) CLINs, and the six-month Option to Extend Services, as calculated in Attachment 2. The calculation will be based upon the mandatory April 23, 2026 BPN index price for the AePEX Energy: Las Vegas, NV posting.

Reasonableness and Completeness: The Government will evaluate the total evaluated price for reasonableness. The Government will verify the offeror's submitted proof of the April 23, 2026, AePEX Energy: Las Vegas, NV BPN index price to ensure calculation accuracy. The Government will also evaluate the proposed fully burdened markup/margin, which must cover all costs including, but not limited to, transportation, freight, labor, tank provision and maintenance, administrative overhead, G&A expenses, and profit. A proposed markup that is determined to be unrealistically low or otherwise unreasonable may render a quote ineligible for award. The Government may also check for unbalanced pricing between CLINs.
