The document outlines sample preparation, analysis methods, and standards for evaluating total metal concentration in fertilizers. It specifies analytical techniques, including Atomic Absorption and Inductively Coupled Plasma/Mass Spectroscopy (ICP/MS), with target detection limits for various metals such as Arsenic, Cadmium, and Lead, all set at less than 1.0000 ppm, except for Mercury, which requires more precise methods (7470A, 7471A) with a limit of <0.5000 ppm. Laboratory analyses must adhere to the U.S. Environmental Protection Agency’s SW-846 publication, which provides comprehensive testing methods for solid waste. For accessibility, the latest SW-846 version can be found online or requested in print from the National Technical Information Service (NTIS). The file's structure consists of several attachments, including references to secondary containment areas and tank management. Overall, the document serves as a technical guideline for organizations involved in environmental analysis, ensuring compliance with federal standards crucial for government RFPs, grants, and local proposals aimed at environmental safety and regulation adherence.
The U.S. Army Corps of Engineers, Walla Walla District, is seeking proposals for the supply and delivery of liquid fertilizer (32-0-0 Urea Ammonium Nitrate) to support nutrient supplementation at Dworshak Reservoir from May through September. Contractors are required to provide storage tanks with 9,000 to 10,000 gallons capacity, along with a pumping system powered by a gas-driven pump capable of transferring the fertilizer to government-owned mobile tanks. Testing of the fertilizer for nutrients and contaminants must be completed prior to delivery, ensuring compliance with EPA standards.
Deliveries are to be coordinated with the project's point of contact, with an emphasis on weekly applications during the designated period. The contract will include strict security requirements for personnel accessing the installation, including training and vetting measures. The expected total quantity of fertilizer does not exceed 43,000 gallons, while past data indicates variable seasonal demand. The document emphasizes adherence to safety protocols, timely delivery, and regulatory compliance, reflecting the project's commitment to enhancing the reservoir's ecological productivity while maintaining rigorous standards.
This government document outlines sample preparation, analysis methods, and standards for determining total metal concentrations in fertilizers, focusing on specific metals such as Arsenic (As), Cadmium (Cd), Lead (Pb), and Mercury (Hg). It specifies analytical methods, including Atomic Absorption and Inductively Coupled Plasma/Mass Spectroscopy (ICP/MS), with established target contamination levels ranging from <1.0000 ppm for most metals to <0.5000 ppm for mercury. The document mandates compliance with the latest U.S. Environmental Protection Agency (EPA) SW-846 test methods for evaluating solid waste. Furthermore, it provides guidance on obtaining the SW-846 publication, either online or through the National Technical Information Service. Overall, the document serves to ensure laboratories adhere to stringent testing standards to safeguard environmental and public health by monitoring fertilizer metal content.
The document is a Request for Proposal (RFP) issued by the U.S. Army Corps of Engineers for the supply and delivery of liquid fertilizer (Urea Ammonium Nitrate, 32-0-0) at the Dworshak Project in Idaho. The contract aims to enhance nutrient supplementation in the Dworshak Reservoir, requiring vendors to provide a storage tank of approximately 10,000 gallons capacity and a pumping system for transferring the fertilizer. The contractor must ensure the fertilizer meets specific environmental standards concerning trace metals and carry out regular testing before delivery.
The RFP includes detailed instructions for prospective bidders on submission processes, including documentation requirements and proposal formatting. A Bidder Inquiry system is established for question submissions, guiding inquiries promptly for potential resolution. Key specifications entail delivering and setting up the fertilizer system by mid-April 2025, with ongoing weekly deliveries from May through September, highlighting a rigid schedule for nutrient application.
Ultimately, the government seeks a responsible vendor offering the best value for the required products while adhering to various federal regulations and environmental standards, reflecting the commitment to sustainable management of the reservoir’s ecosystem.
