About the company
Seaon Environmental LLC, a for-profit limited liability company based in Flagstaff, Arizona, provides oily wastewater purification treatment, wastewater collection and transfer, and related environmental compliance services to the U.S. Navy as a prime contractor competing in full-and-open procurements across multiple indefinite delivery contracts and delivery orders, with no SBA set-aside designations.
Seaon Environmental delivers concrete maritime environmental services centered on oily wastewater (OWW) purification, collection, holding, transfer, treatment, and disposal of black and gray wastewater, used oil fuel recycling, and chemical holding tank (CHT) services. The vendor operates almost exclusively under three large single-award IDCs with Naval Sea Systems Command, Naval Facilities Engineering Command, and U.S. Pacific Fleet Forces. Representative recent work includes a $8,047,420 delivery order from Naval Sea Systems Command on March 9, 2026, for oily wastewater purification service in Japan (ultimate completion March 9, 2027); a $1,083,842.60 delivery order from Naval Facilities Engineering Command on April 1, 2026, for recurring wastewater and oily wastewater collection, holding, transfer, and treatment services at Commander Fleet Activities Sasebo through March 31, 2027; and a $1,230,969.31 delivery order from Naval Facilities Engineering Command on April 1, 2025, for third option period recurring environmental services at Sasebo through March 31, 2026.
Customer concentration is extreme. Naval Sea Systems Command anchors 148 awards (48% of the portfolio) valued at $99.2 million combined potential value, while U.S. Pacific Fleet Forces accounts for 110 awards worth $11.3 million. Together, these two commands represent 84% of recent awards and 92% of combined potential value. Naval Facilities Engineering Command, Naval Supply Systems Command, Military Sealift Command, Navy Installations Command, the Department of the Coast Guard, and the Department of the Navy combined account for the remaining awards. The concentration reflects Seaon Environmental's role as a dedicated environmental services provider to Navy Pacific operations, with all work performed at or near naval installations in Japan, particularly Commander Fleet Activities Okinawa and Sasebo, plus Strategic Readiness Facilities and support for transient vessels.
Seaon Environmental holds five named parent IDCs. The largest, Indefinite Delivery Contract N6264920D0013 with Naval Sea Systems Command, carries 241 task orders valued at $47.6 million combined potential value. IDC N4008422D6303 with Naval Facilities Engineering Command for Sasebo services carries 30 task orders worth $8.6 million. IDC N6824621D0001 with U.S. Pacific Fleet Forces for Okinawa operations carries 21 task orders valued at $2.1 million. IDC N6264926DB002, also with Naval Sea Systems Command, carries 3 task orders worth $9 million. IDC N4008423D3603 carries 1 task order worth $985 thousand. All five vehicles are single-award contracts with firm fixed-price delivery orders issued by various Navy contracting offices, with no competing awardees.
Activity declined sharply over the past two years—from 70 awards in both 2022 and 2023 to 60 in 2024, 37 in 2025, and only 8 through mid-2026. Four awards with ultimate completion dates in the next twenty-four months carry combined potential value of $10.1 million, presenting recompete exposure. The source captures 310 prime awards (100% of footprint) and zero sub-awards; Seaon Environmental operates as a prime contractor exclusively, with no listed subcontractors across the portfolio. All awards carry full-and-open designation with no set-aside categories (8(a), SDVOSB, HUBZone, WOSB, or other SBA programs). Primary NAICS classification is Hazardous Waste Treatment and Disposal (278 awards); secondary codes are Other Nonhazardous Waste Treatment and Disposal and All Other Miscellaneous Waste Management Services. Work is performed worldwide at Japan-based naval facilities, with administrative oversight rooted in Navy commands at Norfolk, Washington, D.C., and Pacific Fleet headquarters. The vendor's federal contract footprint is narrowly scoped—maritime environmental compliance services for Navy operations—and geographically concentrated in the Western Pacific theater.
