4.2.3 Lot definitions.

4.2.3.1 Type I. A lot is defined as all of the nitrogen supplied in one or more container(s) filled from a single manifold at the same time.

4.2.3.2 Type II. Each filled container shall constitute a lot.

4.2.3.3 Container Assemblies. A shipping conveyance consisting of multiple cylinders or tubes that are interconnected by a single manifold that equalizes the pressure across all cylinders/tubes to form a single unit is considered a single container for the purpose of this specification.

4.2.4 Sample. Each sample shall be of sufficient size to conduct all the quality conformance tests as specified herein. Unless otherwise specified, the quality conformance tests shall be performed on each required sample (see 6.2). When required, an equivalent sample shall be forwarded to a laboratory designated by the procuring activity for testing.

4.2.4.1 Sampling methods. Each sample taken for analysis shall be representative of the entire contents of the container being sampled. All equipment used shall be made of suitable materials. Unless otherwise specified in the acquisition requirements (see 6.2), sampling shall be accomplished by one of the following methods.

a. Type I, gaseous nitrogen may be sampled in accordance with ASTM F 307 and Type II, liquid nitrogen may be sampled in accordance with ASTM F 310. It is critical that the outlet of the sampling port be clean and free of contaminants.

b. Connect the shipping container being sampled directly to the analytical equipment using suitable pressure regulation as required to prevent over-pressurization of the equipment.

4.2.5 Non-Bulk Containers. Non-bulk containers are defined as containers of 400 liters or less water capacity. The number of containers filled with Type I (gaseous) nitrogen selected for sampling from each lot shall be in accordance with Table II. The first and last containers to be filled within a given lot are typically sampled. Other samples may be selected at random. Every container filled with Type II (liquid) nitrogen shall constitute a lot and will be sampled.

4.2.6 Bulk transports. Bulk containers are defined as containers of more than 400 liters water capacity. Each bulk container filled with Type I (gaseous) or Type II (liquid) nitrogen constitute a lot and shall be sampled.

4.2.6.1 Continuous service. Unless otherwise specified by the procuring activity, the following sample option for nitrogen shall be used for storage and transport tanks engaged in continuous nitrogen service (see 6.2). Contractor shall sample the contents of each transport tank engaged in continuous nitrogen service at least once every seven days at uniform intervals of time. Samples shall be taken from the filled transport tanks. Contractor shall sample the contents of each transport tank when entering continuous service and when the transport tank has remained empty for a period greater than 24 hours.

When empty, all ports and vents shall remain closed to the atmosphere. While in continuous service, compliance with quality conformance tests specified herein shall be determined by sampling the filling point storage tank after each addition or, in case of continuous production, at established intervals not less frequent than once every 24 hours. When a storage tank is being filled during a change of duty shift, sampling shall be performed after filling. (see 6.5.1)

4.2.7 Pipelines. Unless otherwise specified in the contract, the following sampling plan shall be used for pipelines: Sampling to determine specification compliance shall be accomplished by drawing liquid phase samples from each filled container transporting liquid for conversion to gas and by drawing samples from the gas supplied into the user's system (see 6.2).

4.2.7.1 Liquid phase samples. Liquid phase samples shall be tested for each parameter in applicable grade of Type II nitrogen. Sampling under the "continuous service" provisions can be applied.

4.2.7.2 Gas phase samples.

a. Samples shall be tested for each parameter in the applicable grade of Type I nitrogen.

Samples shall be drawn in accordance with 4.2.4 from a point immediately prior to entering the user's system. The frequency of sampling shall not be less than once every seven days at regular intervals.

b. When specified in contract, in-line samples shall be drawn and tested with continuous monitors for each parameter specified in contract for the applicable grade of Type I nitrogen. Each analyzer shall be equipped with a permanent recording device. When specified in contract, an alarm system to indicate contaminant contents in excess of specified maximum shall be provided (see 6.2).

c. After internal exposure of the pipeline to the atmosphere or other foreign materials, a sample of gas shall be taken from the pipeline prior to delivery into the user's system at a point between the final filter and the interface with the Government system. The sample shall be tested for each parameter in applicable grade of Type I nitrogen. After cleaning operation, the sample shall also be tested for contamination by vapors from the cleaning materials.

4.3 Rejection. When any sample tested in accordance with 4.4 fails to conform to the requirements specified herein, the entire lot represented by the sample shall be rejected.

4.4 Analytical procedures. Unless otherwise specified, samples shall be analyzed according to the procedures described in 4.4.2 (see 6.2). Calibration gas standards may be required to calibrate (zero and span) analytical instruments used to determine the purity and impurity contents of the nitrogen. The accuracy of the calibration gas standards is to be traceable to the National Institute of Standards and Technology.

4.4.1 Nitrogen content. The nitrogen content in percent shall be found by determining the aggregate impurities by the methods described in 4.4.2. The nitrogen purity is the value obtained when the aggregate impurities, expressed as volume percent, is subtracted from 100 percent.

4.4.2 Impurities. Methods shall be selected from those of CGA G-10.1.

4.4.3 Particulate content. A filter holder assembly, (Pall Life Sciences part number 2220), or equivalent modified as shown on Figure 1 shall be attached to the withdrawal line of the vessel to be utilized to fill the tanks. A preweighed filter paper (47 mm glass fiber paper, type A/E or equivalent) shall be placed on top of another filter of the same kind. The filters shall then be placed on the porous filter support, which, in turn, shall be placed in the filter holder as shown on Figure 1. The male threads of the filter holder shall be wrapped with thin, nonadhesive-backed polytetrafluorethylene tape A-A-58092 or equivalent to prevent galling of the threads. The holder shall be tightened by hand as tight as possible to prevent bypassing of the filter element. The discharge liquid from the filter housing shall be collected in a clean, uninsulated, ambient temperature vessel marked to indicate when 5 liters of liquid have been collected. The liquid flow shall be terminated when 5 liters of liquid have been collected. The filter holder shall be removed from the line and permitted to reach ambient temperature. The warmup to ambient temperature may be expedited by use of an oven or other heat source. Care shall be exercised to ensure that any airflow which enters the unit will be directed through the inlet of the assembly to prevent displacing any particles from the surface of the filter. Upon warmup, the other side of the holder shall be wiped with a clean cloth and the holder then disassembled. The filter paper shall be closely inspected.

The test shall be repeated if evidence of either (a) the filter not being securely clamped by uniform depression of its edge; (b) the filter having been cut by the holder; or (c) when dirt particles are detected in the clamped area indicating bypassing had been encountered. The test shall also be repeated when either the bottom filter shows any discoloration or when leakage of liquid from the filter holder is detected.

Upon completion of a valid test the filter shall be removed from the housing and weighed to the nearest

0.1 mg.

4.5 Containers of Type I nitrogen.

4.5.1 Filling pressure. Containers shall be stabilized to 21°C (70°F). Containers shall be tested for proper filling pressure by attaching a calibrated Bourdon-tube gauge or calibrated electronic equivalent gauge to the valve outlet. The gauge shall have scale divisions not greater than 100 kPa (15 psi). Then the valve shall be opened and the internal pressure observed on the gauge. If the internal pressure differs from the applicable filling pressure value by more than 100 kPa (15 psi), the container, and all other containers filled from the same manifold at the same time, shall be rejected.

4.5.2 Leakage. Each Type I nitrogen container shall be tested for leaks at the neck threads, stem packing, and safety device of the valve with leak detection fluid. Valve seat leakage shall be tested after filling has been completed by connecting a hose to the valve outlet and placing the other end of the hose under the surface of a liquid. Methods of leak detection and/or the leak check guidance in CGA P- 15 may also be used.

4.5.3 Inspection and Maintenance. Compressed gas cylinders shall be inspected, maintained, and charged according to MIL-STD-1411.

4.5.3.1 Valves. Valves shall conform to A-A-59860.

4.5.3.2 Color Coding. Government-owned cylinders shall be color coded according to MIL-STD-

101.

FIGURE 1. Filter, Cryogenic Liquids

5. PACKAGING

5.1 Packaging. For acquisition purposes, the packaging requirements shall be as specified in the contract or order (see 6.2). When packaging of materiel is to be performed by DoD or in-house contractor personnel, these personnel need to contact the responsible packaging activity to ascertain packaging requirements. Packaging requirements are maintained by the Inventory Control Point’s packaging activities within the Military Service or Defense Agency, or within the military service’s system commands. Packaging data retrieval is available from the managing Military Department’s or Defense Agency’s automated packaging files, CD-ROM products, or by contacting the responsible packaging activity.

Amendment 2

TO ALL OFFERORS: This amendment will answer questions posed by industry. In addition it revises the Schedule. Also a revised Proposal Format and Content Provision [L2.35] and revised Evaluation Provision [M2.14] is also incorporated into the solicitation via this amendment.

1. Industry Question: CLIN 16 – relates to the support staff being on site and since we have them work 12 hour shifts, we can calculate their hourly & overtime rates. I’m assuming the quantity of 8 is in anticipation of 8 events in the course of a year – correct? So we should multiply the rate times 8 to get an annual contract spend?

GOVERNMENT ANSWER: Yes, 8 is the estimated number of events. This is a requirements contract so the estimate of 8 is a best estimate but the number of actual events may be more or less than 8. The CLIN proposal is looking for offerors to insert their proposed per person per day cost for labor while on site, not an annual roll-up number.

2. Industry Question: CLIN 17 – refers to labor & per diem while in travel status – assume that’s the time on average each support staff travels to arrive at VAFB correct? That will vary depending on staff availability and distance traveled…any suggestions on how we should guesstimate it?

GOVERNMENT ANSWER: See the below listed revised schedule.

3. Industry Question: CLIN 18 – Shout this be “TBD”? We need to seek direct reimbursement for whatever travel arrangements are necessary based on staff availability. Not knowing which staff is coming from where on any given event to support the HFE makes it virtually impossible to guesstimate travel costs – some will be flying and some local staff will be driving…any suggestions or clarification as to how we should respond? Can we opt to quote “TBD” and expect direct reimbursement for actual cost?

GOVERNMENT RESPONSE: See the revised schedule listed below.

4. Industry Question: CLIN 19 – appears similar to CLIN 16. We typically bring the same support staff for any HFE as the task/duties are the same or am I overlooking something here?

GOVERNMENT RESPONSE: See the revised schedule listed below.

5. Industry Question: CLIN 20 – this appears to be similar to CLIN 17. Here again they are typically the same people or am I missing something? Please clarify.

GOVERNMENT RESPONSE: See the revised schedule listed below.

6. Industry Question: CLIN 21 – this one also appears to be similar to CLIN 18. We would prefer to use “TBD” rather than guesstimate high to be sure and cover our costs when we have to fly personnel to the site. Same questions as in CLIN 18. Please comment.

GOVERNMENT RESPONSE: See the revised schedule listed below.

7. Industry Question: CLIN 22 – Why is there differentiation between HFE, Environmental Check, WDR, Static Fire, Launch, etc. The same tasks/duties are performed each time for each HFE. The second line states “Check for HIGH FLOW EVENT” – what does that mean? Please clarify.

GOVERNMENT RESPONSE: See the revised schedule listed below.

8. Industry Question: CLIN 23 – for Mobilization of Distribution Equipment for HEAVY LIFT REQUIREMENTS – since we don’t always know where the resources will come from i.e. which of our air separation plants will have extra LIN available, it’s hard to predict what equipment will be required as it will depend on which plant has the product and how far it is to VAFB. Do you want us to calculate mileage from each plant and define the surcharge amount for each load of LIN, and then quote just the surcharge/additional cost per LIN load? Please advise.

GOVERNMENT RESPONSE: See the revised schedule listed below.

9. Industry Question: In the Statement of Objectives (SOO) under Section 4 HIGH FLOW EVENT, there’s a new stipulation that only allows offerors to bring support staff in less than 24 hours prior to start of a high-flow event

– the current contract provides 48 hours... There are times when a high-flow event that starts at 3AM and less than 24 hours prior for staff to arrive makes it impractical to catch flights and arrive at VAFB in time to go through the extensive checklist and prepare for startup. It could become a safety issue if the guys don’t get adequate rest prior to a strenuous high-flow event. Are you sure the DLA wants us to take additional risks by bringing in tired-sleep deprived staff to prepare for a launch or HFE? More safety incidents occur when employees are overworked or very tired…

GOVERNMENT RESPONSE: The time remains at 24 hours. Re-imbursement for all travel related expenses will be reimbursed under CLIN 0017 in the attached revised schedule.

10. Industry Question. Departing the site within 24 hours following a high-flow event is also a new stipulation. .

Is it safe to assume we will be reimbursed for airline change fees and late check-out/hotel room cancellation fees?

GOVERNMENT RESPONSE: The time remains at 24 hours. Re-imbursement for all travel related expenses will be reimbursed under CLIN 0017 in the attached revised schedule.

11. Industry Question. On page 12 of 17 where the Technical Proposal begins I’m trying to follow the item on page 13 of 17 where the statement (F) (ii) reads “Description of Contractor-furnished equipment at a location other than the Contractor’s facility such as storage tanks. Is the DLA wanting us to describe LIN tanks at VAFB or at our primary production plants located in California?

GOVERNMENT RESPONSE: The proposal is looking for a description of contractor provided equipment that will be placed by the contractor at VAFB in order to meet contract requirements.

12. Industry Question: Is (A) below (F) (ii) requesting Offeror to “Describe all Contractor provided existing equipment…” based current installation at VAFB or at primary production plants?

GOVERNMENT RESPONSE: The proposal is looking for a description of contractor provided equipment that will be placed by the contractor at VAFB in order to meet contract requirements.

B. The following schedule replaces the schedule in the original RFP.
