Under the Pollution Prevention Act of 1990 (PPA), TRI collects information to track industry progress in reducing waste generation and moving towards safer waste management alternatives. Measures that facilities have taken to prevent pollution and reduce the amount of toxic chemicals entering the environment are shown in the table below. Although factors other than these reported practices contribute to year-to-year changes in releases, results are sorted by largest reduction in order to facilitate identification of pollution prevention successes.

78220BLLNC3443E	BLUE LINE CORP (NA)	3443 E COMMERCE ST, SAN ANTONIO, TX 78220	Nickel compounds	325180: Other Basic Inorganic Chemical Manufacturing	2018	57.00	5.00	-91.23	Source Reduction: W33: Installed overflow alarms or automatic shutoff valves - Overflow switch installed to shut off feed pump when level in rundown tank got too high. This would minimize solution leaving the system. Methods to Identify SR Opportunities: T04 : PARTICIPATIVE TEAM MANAGEMENT - Maintenance and production management actively worked together to minimize solution leaving the system. This would improve environmental and economical aspects. Other Environmental Practices: Recycling - Any cleanings, equipment washing, or spills/leaks were collected and added back into the system. Purity was not quite affected in this process. Any solution leaving the system was washed down before collecting.		//enviro.epa.gov/enviro/P2_EF_Query.p2_report?FacilityId=78220BLLNC3443E&ChemicalId=N495&ReportingYear=2018&DocCtrlNum=1318216990186&Opt=0
78220BLLNC3443E	BLUE LINE CORP (NA)	3443 E COMMERCE ST, SAN ANTONIO, TX 78220	Nitrate compounds (water dissociable; reportable only when in aqueous solution)	325180: Other Basic Inorganic Chemical Manufacturing	2016	1,732.33	783.11	-54.79	Other Environmental Practices: Recycling - Nitric acid has been re-used between tanks making similar products to reduce the nitrate compounds that go out into waste water. When tanks are being rinsed for cleaning, the rinse water that contains high nitrate compounds is used in another batch that contains the same compound for dilution. This is also an effort to save nitrate compounds that go to wastewater treatment and save on water usage.		//enviro.epa.gov/enviro/P2_EF_Query.p2_report?FacilityId=78220BLLNC3443E&ChemicalId=N511&ReportingYear=2016&DocCtrlNum=1316215644232&Opt=0

A new system for tracking them all was implemented late 2017 so that they get used in the batches that match chemical identity and purity. Most batches had higher yields in products, which led to less recycled material.		//enviro.epa.gov/enviro/P2_EF_Query.p2_report?FacilityId=78220BLLNC3443E&ChemicalId=N511&ReportingYear=2018&DocCtrlNum=1318216990200&Opt=0

This cuts down the amount of fresh nitric acid having to be used and it still cleans well. By using classifications for batches, the nitric acid of the higher purity batch tank cleaning can go into a tank that will have a lower purity batch. Also, the nitric acid is tested for impurities so that it may go into another tank that needs cleaning if little to no impurities are present.		//enviro.epa.gov/enviro/P2_EF_Query.p2_report?FacilityId=78220BLLNC3443E&ChemicalId=0007697372&ReportingYear=2020&DocCtrlNum=1320218721900&Opt=0

This has reduced amount of nitric used overall, even if a small percentage of Blue Line's overall nitric usage.		//enviro.epa.gov/enviro/P2_EF_Query.p2_report?FacilityId=78220BLLNC3443E&ChemicalId=0007697372&ReportingYear=2016&DocCtrlNum=1316215644244&Opt=0

Methods to Identify SR Opportunities: T04 : PARTICIPATIVE TEAM MANAGEMENT - The Plant Manager and Production Manager work with Production Supervisors to strategically move cleaning nitric solution from tank to tank to reduce the amount of fresh nitric acid needed for cleaning. They also have Chemistry test impurities to verify that the nitric acid used to clean the tanks can also be used in batch production. Source Reduction: Cleaning and recycling of cleaning solutions helped reduce the amount of nitric acid needed by a small amount since nitric acid is used to clean tanks of impurities based on batch specifications. Other Environmental Practices: All nitric acid is neutralized and pH is verified before any discharges to POTW.		//enviro.epa.gov/enviro/P2_EF_Query.p2_report?FacilityId=78220BLLNC3443E&ChemicalId=0007697372&ReportingYear=2024&DocCtrlNum=1324222980031&Opt=0

Other Environmental Practices: Nitric acid is recycled from one tank cleaning to the next when washing tanks of impurities. By doing so, the amount of nitric acid used is reduced while still cleaning tanks to acceptable impurity levels. Higher purity batches require more nitric acid washing to remove any and all material that may stick to internals of the system. These higher purity batches have the nitric acid tested multiple times before using the tanks.		//enviro.epa.gov/enviro/P2_EF_Query.p2_report?FacilityId=78220BLLNC3443E&ChemicalId=0007697372&ReportingYear=2022&DocCtrlNum=1322221028881&Opt=0
