Okinawaken Sangyo Haikibutsushori Cooperative Association

Okinawaken Sangyo Haikibutsushori Cooperative Association, a for-profit cooperative based in Okinawa, Japan, serves as a prime contractor providing environmental and facility maintenance services — grease trap, septic tank, wastewater treatment, regulated medical waste disposal, and portable latrine services — exclusively to U.S. Department of Defense installations in the Okinawa region, with no set-aside designations across its footprint.

The vendor operates a heavily Marine Corps–concentrated portfolio. The U.S. Marine Corps accounts for 84 awards (64% of total) valued at $45 million combined potential value, dominated by recurring delivery orders for grease trap maintenance, septic tank cleaning, and wastewater treatment sludge disposal at Marine Corps Base Camp Smedley D. Butler. The Department of the Air Force Pacific Air Forces ranks second with 17 awards worth $5.9 million, anchored by a $2.57 million purchase order for septic tank pump-out and cleaning services through July 2027 and a $499,999 Blanket Purchase Agreement for grease trap maintenance at Kadena Air Base through August 2026. The Department of the Navy Bureau of Medicine and Surgery holds 16 awards valued at $3.8 million for regulated medical waste and amalgam waste collection and disposal at U.S. Naval Hospital Okinawa. Together, these three customers account for 96% of award count and 93% of combined potential value. The Department of the Army Installation Management Command Pacific Region and the Department of the Air Force round out the customer set with four awards each, totaling less than $1 million.

The vendor holds five primary indefinite-delivery vehicles. The Marine Corps Indefinite Delivery Contract N4008419D2010, awarded January 29, 2024, carries a $12.6 million ceiling through February 28, 2031, and covers grease trap, septic tank, wastewater treatment sludge hopper, sewage lift station, and non-potable water tank maintenance at MCB Butler; three delivery orders totaling $4 million have issued to date, with the most recent (February 23, 2026) valued at $1.4 million and running through February 2027. The Navy's Bureau of Medicine and Surgery Indefinite Delivery Contract N4008423D2200, awarded June 28, 2023, carries a $1 million ceiling through June 30, 2028, for regulated medical waste disposal at Naval Hospital Okinawa; three delivery orders valued between $136 thousand and $167 thousand have issued under the base and first option periods. The Air Force Pacific Air Forces Blanket Purchase Agreement for grease trap maintenance at Kadena Air Base (awarded October 1, 2021, $500 thousand ceiling through August 2026) and the Army Pacific Region Blanket Purchase Agreement for portable latrine services (awarded October 1, 2021, $749 thousand ceiling through September 2026) represent the vendor's secondary vehicle positions. Historical indefinite-delivery contracts N4008407D2001, N4008412D2001, N4008414D2005, and N4008418D2001 collectively generated 68 task orders valued at $9.6 million but are now inactive or nearing completion.

Award activity trended downward from 2023 onward — nine awards in 2023, six in 2024, two in 2025, and one in 2026 — suggesting mature contract performance rather than active pursuit growth. Two awards with combined potential value of $4 million reach ultimate completion within the next twenty-four months, creating limited recompete exposure. The vendor's entire footprint consists of full-and-open, non-set-aside awards, reflecting its geographic specialization and technical expertise in facility operations support rather than small-business competition. All work performs in Japan, with place of performance at U.S. military installations in the Okinawa region.
