Nitrogenous fertilizer manufacturers produce ammonia-based compounds — such as anhydrous ammonia, urea, ammonium nitrate, and ammonium sulfate — through chemical synthesis or by processing sewage and animal waste. Finished or intermediate products may be blended with other nutrients before distribution to agricultural wholesalers, cooperatives, or direct farm customers. Facilities typically involve pressure vessels, reactors, storage tanks, and rail or truck loading infrastructure.
Questions to investigate
- What specific nitrogenous compounds are manufactured, stored, or blended on-site — anhydrous ammonia, ammonium nitrate, urea, or others?
- Are storage quantities of any regulated substances at or near EPA RMP or OSHA PSM threshold levels?
- What is the facility's environmental compliance history, including any prior releases, spills, or regulatory enforcement actions?
- Does the operation involve on-site synthesis, or primarily blending and mixing of purchased materials?
