OSHA's Ammonium Regional Emphasis Program

OSHA has announced it has developed a regional emphasis program for ammonium starting October 1, 2018.
⚡ TL;DR: OSHA’s Ammonium REP targets fertilizer-grade ammonium nitrate and agricultural anhydrous ammonia in Oklahoma, Texas, Arkansas, Louisiana, Kansas, Missouri, and Nebraska. The program was triggered by the 2013 West Fertilizer explosion. If your facility stores or handles these materials in a targeted region, OSHA inspections are likely. Compliance applies under 29 CFR 1910.109(i) (ammonium nitrate) and 29 CFR 1910.111 (anhydrous ammonia).
Who is Affected?
The emphasis program targets fertilizer grade ammonium nitrate and agricultural anhydrous ammonium. Both create a significant hazard of fire and explosion and are toxic to those who handle them.
Companies who store, mix, blend, and distribute these products will be targeted in this program.
⚠️ Why this matters: Ammonium violations produce fatalities. The West Fertilizer explosion in Texas killed 15 people and injured more than 200. OSHA treats ammonium programs as high-hazard and will cite gaps aggressively. If your facility is in a targeted region and stores these materials, an inspection isn’t a question of if—it’s when.
Ammonium nitrate storage issues came into prominence with the 2013 West Fertilizer facility explosion. This regional emphasis program was a recommendation of the Chemical Safety Board’s report following the incident.
Which States are Included?
The regional emphasis includes particular states from OSHA Region VI and OSHA Region VII. These include Oklahoma, Texas, Arkansas and Louisiana from Region VI and Kansas, Missouri and Nebraska from Region VII.
What is the Enforcement Date?
Affected companies will have 90 days from October 1st to get their compliance activities in order before OSHA starts issuing penalties, roughly until the end of the year.
Storage of ammonium nitrate falls under 29 CFR 1910.109(i), and storage and handling of anhydrous ammonia falls under 29 CFR 1910.111. There are other OSHA regulations and requirements which apply to the handling of these chemicals.
What’s Next?
If your company will be affected by this OSHA ammonium regional emphasis program, iSi can help you determine what you need to do to comply and be ready for any upcoming inspection. If you don’t know if you are affected or not, we can help you make that determination.
Most ammonium compliance programs need: documented storage area maps (location, quantity, distance to other structures), written emergency response procedures, employee training on hazards and procedures, ongoing inventory controls, and periodic facility audits. Many facilities don’t know what documentation they’re missing until OSHA arrives.
Frequently Asked Questions
Q: Which states are covered under the Ammonium Regional Emphasis Program?
A: The program covers OSHA Region VI states (Oklahoma, Texas, Arkansas, and Louisiana) and OSHA Region VII states (Kansas, Missouri, and Nebraska). This regional emphasis was implemented following the 2013 West Fertilizer facility explosion in Texas, which prompted the Chemical Safety Board to recommend focused enforcement on ammonium handling and storage.
Q: What types of ammonium products are targeted by this emphasis program?
A: The program specifically targets fertilizer-grade ammonium nitrate and agricultural anhydrous ammonia, both of which create significant fire, explosion, and toxicity hazards. Companies that store, mix, blend, and distribute these materials face elevated OSHA inspection risk in affected regions.
Q: What are the relevant OSHA regulations for ammonium handling?
A: Ammonium nitrate storage falls under 29 CFR 1910.109(i), while anhydrous ammonia storage and handling is governed by 29 CFR 1910.111. Additional OSHA regulations and EPA Process Safety Management (PSM) requirements may apply depending on quantities stored and the facility’s proximity to sensitive areas.
Q: How much time did companies have to achieve compliance when the program began?
A: The program provided a 90-day grace period from October 1, 2018 for affected companies to implement compliance measures before OSHA began issuing penalties. Companies operating in Kansas, Missouri, Nebraska, Oklahoma, Texas, Arkansas, or Louisiana should ensure current compliance with ammonium storage and handling standards.
💰 What non-compliance looks like: A fertilizer distributor in the target region who was caught without proper emergency response procedures, hazard communication, or employee training faced $45,000+ in serious violations. A facility with improper storage distance from occupied buildings faced $65,000+ across multiple citations. Prevention is vastly cheaper.
