4. CURRENT MANAGEMENT APPROACHES ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- 4.1 . MAJOR WASTE STREAM COMPARISONS For each major waste stream,the SB 14 Performance Report is required to contain the following information: i An estimate,in pounds,of the quantity of hazardous waste generated,and the quantity of hazardous waste managed,both on-site and off-site,during the current reporting year;and i An estimate,in pounds,of the quantity of hazardous waste generated,and the quantity of hazardous waste managed,both on site and off site,during the baseline year. As shown by Table 3,the weights of the major waste streams generated from the facility are compared for Baseline Year and Reporting Year along with the type of hazardous waste management approaches. "Hazardous waste management approaches"means methods and techniques of controlling the generation and handling of hazardous waste. Approaches include source reduction,on-site and off-site recycling,on-site and off-site treatment,and disposal. An assessment of the effect of each waste management approach is provided below. 4.2. ASSESSMENT OF WASTE MANAGEMENT APPROACHES For each major waste stream,the Performance Report must contain an assessment of the effect,since the Baseline Year,of each implemented hazardous waste management approach on each of the following: > The weight of hazardous waste generated; > Quantify source reduction achieved; > The properties which cause the waste to be classified as a hazardous waste; > The on-site management of hazardous waste;and > The off-site management of hazardous waste. The assessments should cover any changes in the management of each major hazardous waste stream. The Performance Report should clearly identify the hazardous waste management approach that was implemented, and the impact of that approach on the management of the waste. 4.2.1. Overall Site Performance i Category B: As shown by Tables 1 and 2,the site had generated 45,464 pounds of Category B wastes in the Baseline Year. However,as shown by Table 3,for the same waste classifications relative to the Baseline Year,approximately 61,713 pounds of these same wastes were generated in the Reporting Year,which represents an estimated 36%increase over the last four years. 4.2.2. Barium, Chromium, Ft Silver Waste (CWC #181) As shown by Table 3,since the Baseline Year,this waste stream increased from 8,258 lbs to 14,108 lbs in the Reporting Year,which represents a 70%increase over this time period.For source reduction approaches, Dragon continued operational improvements and administrative measures,including employee training.This waste is being shipped offsite for treatment.The principal factors for this waste stream are business volumes. Production has increased at the facility,resulting in more waste from the plasma cutter operation. Dragon Products, LLC. I SB 14 Hazardous Waste Management Performance Report Trinity Consultants 4-1
