About this file
This justification and approval document outlines proprietary raw materials required for vinyl paint systems used to protect hydraulic structures. The paint formulations utilize specific resins, titanium dioxide products, and additives that have been determined through research and testing to be critical for ensuring coating performance and adhesion. Alternative materials were considered but found to potentially compromise quality control, increase costs for additional testing and evaluation, and result in shorter repaint cycles requiring higher maintenance expenses. As no other coating systems are currently able to meet the needed lifespan and corrosion protection requirements at lower overall costs, a waiver is granted to specify the proprietary raw materials in order to fulfill the agency's needs.
The related federal contract opportunity is a solicitation from the U.S. Army Corps of Engineers Walla Walla District to fabricate one set of trash racks for the McNary Dam.

b. JUSTIFICATION:
i. Resins from one alternate supplier have been identified, but initial laboratory evaluations have indicated problems with quality control.
Providing paint manufacturers with the name of a raw material supplier having products with non-reproducible properties would be counterproductive. Additional potential suppliers have not been identified.
ii. The 3 proprietary TiO2 products are all premium products from their respective manufacturers. Alternative products may be available but identifying suitable products would require both costly and time-consuming research. Funding is not available for this work and there have been no requests for the use of alternatives.
iii. The additives used in paints and many other commercial products are highly proprietary. Research has shown that only the clay-based materials can be used without adversely affecting the adhesion properties of the VZ-108 paint, but even the clay type materials have proprietary surface treatments that affect their performance in the finished paint. Alternative sources of these materials have not been identified and there have been no requests for the use of alternatives.
c. IMPACT: Substitution for the specified products would:
i. Increase the amount of time required to test each batch of paint potentially delaying painting contracts.
ii. Increase the potential for coating failures resulting in significantly shorter repaint schedules and higher maintenance costs.
iii. Necessitate new costs for research to evaluate potential alternative raw materials.
d. ALTERNATIVES: The proprietary raw materials are critical to the performance of the vinyl paint systems. If they are not available, alternate coating systems will need to be used. At this time, the available alternative coating systems will result in greater life cycle costs for the corrosion protection of Corps hydraulic structures.
5 EFFORTS TO OBTAIN AND INCREASE COMPETITION: There is ongoing research to both evaluate commercially available alternatives to the vinyl paints
APPROVAL: In accordance with the authority of 10 U.S.C. 3204(a)(1), as implemented by FAR 6.302-1 and based on the foregoing, I hereby determine that the property needed by the agency is available from a limited number of responsible sources and no other type of property will satisfy the needs of the agency.
DETERMINATION: In accordance with FAR 6.303-2(b)(7), I hereby determine that the anticipated cost to the Government will be fair and reasonable.
CONTRACTING OFFICER’S CERTIFIFCATION: In accordance with FAR 6.303- 2(b)(12), I certify that this Justification & Approval is accurate and complete to the best of my knowledge and belief.
