Methods to Identify SR Opportunities: T11: Other
Source Reduction - Company is looking into replacing anhydrous ammonia with liquid hydrogen in the production process
Other Barriers to Source Reduction - Company is considering removing the use of anhydrous ammonia from the facility but is not ready to implement changes at this time
2023 Source Reduction:: S25: Other process modifications made[-100%]

2019 Barriers: B6-Barriers to P2 B6 - Pollution prevention previously implemented - additional reduction does not appear technically or economically feas
Barriers: B8-Barriers to P2 B8 - A reduction does not appear to be technically feasible

Barriers to P2: B8 - A reduction does not appear to be technically feasible - The elimination of using the dissociated ammonia (DA) would prevent manufacturing of some parts that require sintering in a reduction atmosphere provided by the DA.

Barriers to P2: B6 - Pollution prevention previously implemented - additional reduction does not appear technically or economically feas - Continued practices in minimizing the use of the bulk ammonia used for dissociation by 1) shutting down furnaces when not in use on weekends and plant shutdown periods and slow production periods; and 2) using the large sintering furnace in batches for upcoming quarterly production. The alternative to ammonia requires the storage of hydrogen gas, an extremely flammable material.
2018 Barriers: B6-Barriers to P2 B6 - Pollution prevention previously implemented - additional reduction does not appear technically or economically feas
Barriers: B8-Barriers to P2 B8 - A reduction does not appear to be technically feasible

Barriers to P2: B8 - A reduction does not appear to be technically feasible - The alternative to using dissociated ammonia (DA) is using bulk hydrogen, another highly flammable material. The elimination of using DA would also prevent manufacturing of some of the company's products that require sintering in a reduction atmosphere under high temperatures provided by the DA.

Barriers to P2: B6 - Pollution prevention previously implemented - additional reduction does not appear technically or economically feas - Continued practices in minimizing the use of the bulk ammonia for dissociation by: 1) shutting down furnaces and ammonia crackers when not needed for weekends, shutdown periods and slow times in production activity; and 2) using the large sintering furnace in batches for upcoming quarterly manufacturing. Ammonia usage decreased 2% despite a 25% production increase.
2017 Barriers: B6-Barriers to P2 B6 - Pollution prevention previously implemented - additional reduction does not appear technically or economically feas
Barriers: B7-No Information B7 - No known substitutes or alternative technologies.

Barriers to P2: B6 - Pollution prevention previously implemented - additional reduction does not appear technically or economically feas - Already minimized use of ammonia in dissociation process by: 1) shutting down furnaces on weekends/when manufacturing not running; and 2) running the sintering process in a minimum number of batches for the upcoming quarter's production. We continued these practices last year, reducing consumption of anhydrous ammonia by 7.9%
2016 Source Reduction:: W13: Improved maintenance scheduling, recordkeeping, or procedures
Methods to Identify SR Opportunities: T04: Participative team management
2015 Source Reduction:: W13: Improved maintenance scheduling, recordkeeping, or procedures
Source Reduction:: W58: Other process modifications
Methods to Identify SR Opportunities: T04: Participative team management
Methods to Identify SR Opportunities: T11: Other
Source Reduction - Under the direction of the new VP of Operations, shut down most of the furnaces that utilized dissociated ammonia on the weekends.
Source Reduction - Under the direction of the new VP of Operations, instituted the practice of running several months of sintered products over a couple of weeks, allowing greater shutdown periods of the largest furnace using dissociated ammonia.
2013 Source Reduction:: W58: Other process modifications
Methods to Identify SR Opportunities: T11: Other
Source Reduction - Retired furnaces no longer needed in production.
2008 Source Reduction:: W19: Other changes in operating practices
Methods to Identify SR Opportunities: T04: Participative team management
2002 Source Reduction:: W32: Improved procedures for loading, unloading, and transfer operations
Source Reduction:: W52: Modified equipment, layout, or piping
