Accepted Answer

Reintegrating a process by-product back into the same process as a raw material

Answer

Sending waste off-site to a certified recycling facility

Answer

Recycling materials through a municipal collection program

Answer

Recovering energy from waste through combustion

Question 2

An environmental auditor reviewing a facility's Tier II chemical inventory notices a sharp increase in reported acetone quantities. In a P2 context, what is the most likely root cause to investigate?

Accepted Answer

Increased production volume without corresponding process efficiency improvements

Answer

Changes in federal reporting thresholds for acetone

Answer

Errors in the facility's emergency response plan

Answer

Soil contamination from historic acetone spills

Question 3

The EPA's 33/50 Program was a voluntary initiative that asked companies to reduce releases of 17 priority chemicals. The primary mechanism for achieving these reductions was:

Accepted Answer

Voluntary commitments to source reduction and recycling

Answer

Mandatory pollution control permits for listed chemicals

Answer

Tax incentives for installing end-of-pipe controls

Answer

Mandatory substitution of all listed chemicals by a set date

Question 4

Which document typically serves as the baseline for a facility-level pollution prevention planning effort?

Accepted Answer

A material balance or process flow analysis

Answer

The facility's NPDES discharge permit

Answer

The facility's emergency response plan

Answer

Annual RCRA waste manifests

Question 5

A facility reduces its hazardous waste generation by implementing better housekeeping practices such as promptly closing solvent containers and fixing dripping valves. This strategy is classified as:

Accepted Answer

Good operating practices — source reduction

Answer

End-of-pipe treatment

Answer

Recycling and materials recovery

Answer

Pollution trading and offsets

Question 6

Under RCRA, when does a material being reclaimed (recycled) still qualify as a solid waste?

Accepted Answer

When it is stored in speculative accumulation before reclamation

Answer

When it is reclaimed in a closed-loop within the same process unit

Answer

When it is directly reused as a feedstock without processing

Answer

When a legitimate market exists for the reclaimed material

Question 7

A Pollution Prevention Opportunity Assessment (PPOA) at an electroplating facility identifies dragout of plating chemicals as a major waste source. The most effective P2 control for dragout is:

Accepted Answer

Installing drip racks and drag-out recovery tanks after plating baths

Answer

Increasing the concentration of the plating bath

Answer

Adding additional end-of-pipe wastewater treatment capacity

Answer

Reducing the frequency of wastewater discharge events
