Silverback Associates LLC

Silverback Associates LLC, a Black American-owned, for-profit limited liability partnership based in Katy, Texas, supplies petroleum products, construction materials, and specialized logistics services to federal civilian and defense agencies as a prime contractor operating predominantly under total small business set-asides. The vendor competes entirely as a prime (100% of recent awards); it does not subcontract.

Silverback's capability portfolio centers on fuel procurement and delivery. The vendor holds 16 awards under NAICS 324110 (Petroleum Refineries) and PSC 9140 (Fuel Oils), supplying aviation turbine fuel, kerosene, diesel, dyed diesel, and unleaded fuel to the Defense Logistics Agency, the U.S. Air Force, the Department of the Interior's Fish and Wildlife Service, and the Department of the Army. Representative fuel awards include a $551,428 firm fixed-price purchase order from Army Northeast Region for annual Ultra Low Sulfur Diesel delivery to Fort Knox generators and equipment through September 2026; a $700,000 five-year BPA from Fish and Wildlife Service Region 8 for unleaded and dyed diesel fuel to Midway Atoll National Wildlife Refuge in Hawaii (two calls issued against it, valued at $167,349 and $173,395); and a $257,996 purchase order from Fish and Wildlife Service Region 1 for approximately 43,000 gallons of dyed diesel fuel #2 to Midway Atoll, requiring fuel-over-water delivery certification and harbor access credentials. Beyond fuel, the vendor holds a $7,500,000 five-year BPA from USDA Forest Service Region 8 for vegetation management services including non-native invasive species treatment, hazard tree felling, and Red-Cockaded Woodpecker monitoring on National Forests in Texas; a $7,000,000 five-year aggregate supply BPA from Forest Service Croatan Ranger District in North Carolina; and a $15,000,000 BPA from FEMA for direct-lease residential property management to provide temporary housing assistance to disaster-displaced applicants in Florida.

Customer concentration by potential value is heavily weighted toward large BPA vehicles. FEMA accounts for $15 million (45% of combined potential value) on a single direct-lease housing BPA; USDA Forest Service Region 8 holds $14.6 million across three vegetation-management and aggregate-supply vehicles; Fish and Wildlife Service entities collectively hold approximately $1.5 million across five BPAs and purchase orders. By award count, Defense Logistics Agency Energy leads with nine awards ($374 thousand combined potential value), indicating high-frequency, lower-dollar fuel calls. The source data covers fifteen distinct customer agencies, with 64% of awards concentrated in the top five customers.

Silverback holds eight active Blanket Purchase Agreements with ceilings ranging from $25,000 (Joint Munitions Command road materials, Pine Bluff Arsenal) to $15,000,000 (FEMA housing). Most recently, the vendor was awarded a $250,000 BPA from Fish and Wildlife Service Region 3 on May 11, 2026, for bulk fuel and LPG tank leasing at Necedah National Wildlife Refuge in Wisconsin through June 2031. The source identifies two BPAs by vehicle number (BPA 140F0S24A0056 with two task orders and BPA 12444124A0012 with one task order), though most BPAs in the portfolio are single-award vehicles with no pre-obligated funds. Awards issued under these BPAs span purchase orders and BPA calls valued from approximately $4,150 to $551,428.

Activity has remained relatively consistent across the past three years: 12 awards in 2024, 11 in 2025, and 5 year-to-date in 2026. Two awards carry ultimate completion dates within the next twenty-four months, totaling $817 thousand in combined potential value and therefore subject to recompete exposure. The portfolio shows 28 total awards with combined potential value of $33.4 million, but only $1.1 million (3%) has been obligated, indicating that most awards represent ceiling values on indefinite delivery vehicles rather than firm obligations. Beyond fuel work, the vendor supplies American Landmaster EV UTVs to the Bureau of Prisons (May 2024, $43,573), parking rental and shuttle services to DLA Energy in Houston (April 2024–April 2027, $265,888), HVAC equipment installation to NASA Armstrong Flight Research Center (November 2025, $14,184), and reclaimer/mixer services to the Marine Corps. All significant fuel and logistics awards are designated as total small business set-asides; full-and-open BPAs (particularly those with FEMA and Forest Service) reflect Silverback's competitive positioning in non-reserved procurement.
