Road Chemicals

The South Dakota Department of Transportation (SDDOT) is seeking a statewide contract for road chemicals, specifically road salt and liquid magnesium chloride for winter road maintenance operations. The procurement covers two primary salt categories: ASTM D632 Type 1, Grade 1 and Grade 2 Sodium Chloride, and ASTM D632-01, Type 1, Grade 1 Brining Salt, along with corrosion-inhibited liquid magnesium chloride. Vendors must provide comprehensive product details, including anti-caking agent specifications, and meet stringent quality control standards outlined in the specifications. The contract requires delivery of road salt and liquid magnesium chloride to multiple regions including Aberdeen, Mitchell, Pierre, and Rapid City, with specific delivery windows from September 1st to after November 1st. The procurement process demands that suppliers submit certified test reports demonstrating compliance with salt specifications, including purity, gradation, and chemical composition. The solicitation was posted on June 17, 2025, with proposals due by July 8, 2025, and the contract will cover winter maintenance operations for the 2024-2025 and 2025-2026 seasons.

The procurement appears to be open to all qualified vendors, with the State of South Dakota Vendor Manual suggesting preferences for resident businesses, minority-owned enterprises, and local vendors. While no specific set-aside designations are explicitly mentioned, the manual emphasizes open competition and non-discrimination in the bidding process. Vendors must comply with comprehensive requirements, including maintaining appropriate insurance, adhering to state and federal regulations, and meeting detailed product specifications. The total estimated procurement volume is substantial, with projections ranging from 7,125 tons of road salt for the Aberdeen Region to 24,600 tons for the Mitchell Region, and 156,000 gallons of liquid magnesium chloride for the Rapid City Region in the 2025-2026 season. Pricing includes a fuel cost adjustment mechanism, with a base diesel fuel price of $3.439 per gallon as of June 3, 2025. The contract includes a rigorous quality control framework with liquidated damages ranging from 10% to 100% for non-compliance, and potential contract termination if two shipments fail to meet specifications.
