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.

Other Environmental Practices: Waste Treatment - Our nitric acid and pickling rinse waters are treated in-house and neutralized prior to discharge to the sanitary sewer as per our sanitary authority Industrial Discharge Permit. All acid is neutralized and no longer detrimental to the environment. Other Environmental Practices: Our rinse waters are treated in-house and neutralized prior to discharge to the sanitary sewer as per our sanitary authority Industrial Discharge Permit. All acid is neutralized and no longer detrimental to the environment. Our discharge permit requires the pH of the discharge to be between 5-9.		//enviro.epa.gov/enviro/P2_EF_Query.p2_report?FacilityId=16738LLGHN14EGB&ChemicalId=0007697372&ReportingYear=2022&DocCtrlNum=1322220759676&Opt=0

We also use more dilute nitric acid solutions after our electropolishing processing. Methods to Identify SR Opportunities: T11 : OTHER - We have both nitric acid passivation and citric acid passivation in dedicated process tanks. The volumes remain constant throughout the year.		//enviro.epa.gov/enviro/P2_EF_Query.p2_report?FacilityId=16738LLGHN14EGB&ChemicalId=0007697372&ReportingYear=2018&DocCtrlNum=1318217645744&Opt=0

Other Environmental Practices: Our wastewater treatment process includes raising the pH to 4-5 with a slurry of magnesium hydroxide & lime followed by sodium dimethyldithiocarbamate (DTC) to precipitate metals, caustic soda, if needed to reach pH 9.5-10 followed by an anionic flocculant. All acid is neutralized and the sludge is dewatered with a rotary drum vacuum filter.		//enviro.epa.gov/enviro/P2_EF_Query.p2_report?FacilityId=16738LLGHN14EGB&ChemicalId=0007697372&ReportingYear=2024&DocCtrlNum=1324222561514&Opt=0
