Pollution Prevention (P2) and TRI
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. Many facilities provide descriptions on measures they have taken to prevent pollution and reduce the amount of toxic chemicals entering the environment. As a result, TRI serves as a tool for identifying effective environmental practices and highlighting pollution prevention successes.

Source Reduction Activities Reported to TRI
For 2015, a total of 2,424 facilities (11% of all TRI facilities) reported initiating 7,508 source reduction activities. Good operating practices, process modifications, and spill and leak prevention were the activities reported most frequently.
Click on the legend or graph to see examples of source reduction activities.
- Good Operating Practices (3,002)
- Process Modifications (1,578)
- Spill and Leak Prevention (941)
- A petroleum terminal installed spill kits and drain covers in high-risk areas to prevent benzene spills from leaving through storm water drains.
- A chemical manufacturing facility worked with a leak detection and repair contractor to monitor their anhydrous ammonia system to reduce fugitive emissions.
- Raw Material Modifications (656)
- A motor vehicle parts manufacturer eliminated use of N-methyl-2-pyrrolidone (NMP) as a reducing solvent and when possible started using paints that do not contain NMP.
- A rubber product manufacturer has been replacing di (2-ethylhexyl) phthalate with more environmentally friendly alternatives for its rubber formulations.
- Inventory Control (686)
- A storage battery manufacturer worked with a vendor to understand shelf-life risks and perform in-house lab testing to identify issues involved with using recently outdated cobalt material.
- For better control over the volume of nitric acid added to chromate solution, a fabricated metal facility changed container size from 15 gallons to 1 gallon bottles.
- Product Modifications (300)
- Cleaning and Degreasing (182)
- A glass manufacturer installed a deionized water cleaning system which produces cleaner product for the calibration operation that uses mercury. As a result, less maintenance is required, resulting in decreased mercury waste.
- With the help of a vendor, a food manufacturing facility substituted a high nitric acid sanitation chemical to an equally effective low nitric acid chemical.
- Surface Preparation and Finishing (163)
- A plastic parts manufacturer worked with their paint supplier to select a water-based coatings that would perform as well as a solvent-based coating, resulting in a large reduction of xylene usage.
- A household cooking appliance manufacturer upgraded their spray guns to provide better coverage and use less nickel material.
