Table 394 Types Of Emissions And Discharges

Direct process streams (including after treatment) Fugitive emissions

Oils, lubricants, fuels, chlorofluorocarbons, heat transfer fluids Noncontact process water (e.g., cooling tower water and steam)

Batch process waste (e.g., dirty filters, fly ash, and water washes) Packaging materials Old equipment disposal Office and cafeteria waste Contaminated soil Contaminated groundwater Sediment and erosion control Stormwater runoff discharges Construction debris


1. Name of project (process step, production unit, plant)

2. Operating unit

3. Person completing this analysis

4. List each raw material and its major constituents or contaminants used in this process step, production unit, or plant

5. List each stream by type (feed, intermediate, recycle, nonuseful)

State Potential

Stream Stream Name (Vapor, Quantity Environmental

Type and Number Liquid, Solid) (Volume) Issue(s)

Dredging in a water body or any activity that impacts wetlands

Erosion and sedimentation control Monitoring or dewatering wells

Any action that constructs or alters landfills or land-treatment sites

Any system that constructs or alters water systems Any system that constructs or alters sanitary wastewater collection or treatment systems Stormwater runoff


Compliance is determined from the emission and discharge limits specified in the application permit. Going beyond the regulatory requirements and company goals can im prove goodwill or image, proactively address possible future regulations, and enhance the company's competitive advantage. If a company decides to go beyond the regulatory requirements, it should do so via waste reduction or reuse rather than waste treatment.


An accurate flow sheet that identifies all major process streams and their composition is important for meaningful waste minimization results.

First, all process streams should be classified into one of the four categories—nonuseful (waste), feed, intermediate, and recyclable—with potential environmental issues noted. Checklist A shown in Table 3.9.5 can be used for this analysis.


1. Name of project (process step, production unit, plant)

2. Operating unit

3. Person completing this analysis

4. Stream information (see Nonuseful Streams on Checklist A, Question #5) Stream Number

Stream Name

State (Vapor, Liquid, Solid)

5. What technologies, operating conditions, and process changes are being evaluated to:

a. Minimize this stream at the source?

b. Reuse, recover, or recycle this stream further than originally planned?

c. Process this stream into a useful product not originally planned?

d. Reduce the pollution potential, toxicity, or hazardous nature of this stream?

6. What other technologies, operating conditions, and process changes must be evaluated to:

a. Totally eliminate this stream at the source?

b. Allow reuse, recovery, or recycling of the stream?

c. Develop a useful product?

d. Reduce the pollution potential, toxicity, and hazardous nature of this stream?

7. How could raw material changes eliminate or reduce this nonuseful stream (See Checklist A, Question #4)?

8. What considerations are being given to combining or segregating streams to enhance recycling and reuse or optimize treatment?

9. Does this stream have fuel value? If so, what is being done to recover this fuel value?

10. What consideration is being given to using this stream as a raw material in other company production lines?

11. How does the way in which this stream is handled meet or exceed corporate, operating unit, and site waste elimination or minimization goals?

12. What is the regulatory inventory status (if any) of the chemical components of this stream? Do any premanufacture regulatory requirements exist for these components?

Fill out a separate form for each Nonuseful Stream (prior to treatment or abatement) that is not recycled internally in the manufacturing process via hard piping.
