Title: Residual Risk and Technology Review Amendments to the Phosphoric Acid and Phosphate Fertilizer Production NESHAPs 
Abstract: Phosphate rock is the primary raw material for phosphoric acid, which in turn is the raw material for phosphate fertilizer. These 2 rules are grouped together because their production processes are usually located at the same facility. Part 63 NESHAPs for phosphoric acid and phosphate fertilizer (subparts AA and BB, respectively) were promulgated in June 1999. Facilities subject to these rules were required to be in compliance by June 2002. The Clean Air Act requires EPA to address the risk remaining to the public (ie., a 'risk review') within 8 years after promulgation of the MACT standards. We must also conduct a technology review of the source categories within 8 years to determine whether new technology exists to reduce emissions of hazardous air pollutants (HAP) below the levels established by the MACT standards. For purposes of expediency, these 2 reviews are combined together and called a risk and technology review, or RTR. The amendments will address both risk reduction and technology advancement for the phosphoric acid and phosphate fertilizer source categories. There are no known small businesses in this source category. Proposal and promulgation dates have been scheduled under a settlement agreement for the RTR rules. The RTR amendments to these NESHAPs are due for proposal on 10/31/2012 and promulgation on 10/31/2013.
