Question 1
A state receives a Pollution Prevention Act grant and uses it to run a source reduction program for local businesses. At the end of the year, the state's program office has collected case studies and data from the businesses it assisted. Under the Act, what must the state do with this information?

Answer: A. Make it available to the EPA Administrator, because the grant generated it
The Pollution Prevention Act says states receiving these grants must make information generated under the grants available to the EPA Administrator. Keeping it confidential, sending it to Congress, or waiting for a later request are not what the Act says.
On the job
A state environmental agency used a Pollution Prevention Act grant to fund on-site technical visits to dairies, laundries and auto body shops. One office analyst notes that the visit reports include before-and-after measurements, and asks whether those can stay inside the agency. The program supervisor points out that states receiving these grants must make information generated under them available to the EPA Administrator. The reports are organized and submitted.

Question 2
A paint-finishing shop often throws away partly used cans of hazardous coating that pass their shelf life before anyone uses them. The shop adopts a first-in, first-out inventory system and orders smaller lots. Hazardous coating waste drops sharply, and so does the hazard from its disposal. The safety manager must decide whether this change counts as source reduction under the Pollution Prevention Act.

Answer: B. It counts, because the Act lists improvements in inventory control among source reduction practices.
The Pollution Prevention Act lists inventory control, housekeeping, maintenance and training improvements as source reduction practices when they cut waste and hazard. The shop's change qualifies. Source reduction is not limited to equipment changes or product redesign, and it applies before recycling, treatment or disposal, so recycling is not required.
On the job
A plant engineer at a metal fabrication shop reviews the training and maintenance programs while preparing a waste-minimization report. Operators had been overfilling parts-washer tanks, and spent solvent was drained early and shipped off as hazardous waste. After a short refresher course and a revised tank-servicing schedule, far less solvent is discarded. The engineer logs both changes as source reduction, because the Pollution Prevention Act counts improvements in training and maintenance, not only new equipment.

Question 3
A metal-finishing plant currently cleans parts with a solvent that ends up in its waste stream. The environmental manager proposes four changes. Which change counts as source reduction under the Pollution Prevention Act?
Show answer and source: Pollution Prevention Act of 1990, 42 U.S.C. 13101-13109, PDF p. 1
Answer: C. Replacing the solvent with a water-based cleaner that creates less hazardous waste
The Pollution Prevention Act defines source reduction to include substitution of raw materials. Swapping in a less hazardous cleaner cuts waste at the source. Off-site treatment, on-site burning, and landfill disposal all handle waste after it is created, so none of them reduces what enters the waste stream.
On the job
An EHS manager at a printed circuit board plant wants to shrink the hazardous waste from acid etching baths. Her team weighs installing a better wastewater treatment unit against changing the chemistry used in the process. She backs reformulating the etchant to a less hazardous product, since the Pollution Prevention Act counts substitution of raw materials as source reduction and the change prevents waste from being generated.
