Propane Delivery and Tank Rental for Howard Hanson Dam and Mud Mountain Dam in Washington State

SOLICITATION CANCELLED. The U.S. Army Corps of Engineers Seattle District issued Amendment 0004 on October 8, 2026, canceling Solicitation W912DW26QA073 in its entirety due to changes in the requirement. The original solicitation, posted September 9 with a proposal deadline of October 8, sought a Women-Owned Small Business contractor (100% set-aside) to provide propane delivery and tank leasing at Howard Hanson Dam in Ravensdale, Washington and Mud Mountain Dam in Enumclaw, Washington on a firm fixed-price basis for one base year plus four one-year option periods through September 2031.

Had the procurement proceeded, place of performance would have been Enumclaw and Ravensdale, Washington. At Howard Hanson Dam, the contractor would have delivered propane to one government-owned 500-gallon tank with automatic deliveries every two weeks October through March and monthly April through September, plus on-call emergency delivery within 48 hours. At Mud Mountain Dam, the contractor would have leased four propane tanks (three 500-gallon, one 250-gallon) and delivered propane to those four plus one government-owned 500-gallon tank with automatic deliveries every two weeks November through March and on-call service April through October. Estimated annual consumption was 3,000 gallons at Howard Hanson Dam and 6,500 gallons at Mud Mountain Dam, used exclusively for building heating.

Pricing was required as firm fixed price per gallon of propane plus monthly tank lease rates, with pricing valid for 60 days. Award would have been made to the lowest priced, responsible vendor whose quote conformed to requirements and included a complete price schedule.
