Environmental Stewardship

• It is the responsibility of all employees to
  manage chemical waste in a reasonable manner.
• Failure to do so can result in harm to other
  employees and/or destruction of work areas due to
  fires, explosions, or spills.

3
Resource Conservation and Recovery Act (RCRA)

• RCRA govern handling and disposal procedures of
  certain laboratory wastes that are categorized as
  hazardous.
• USPSNL is considered a small quantity generator
  of hazardous waste, which means less than 100 kg
  or 22 pounds of hazardous waste is produced per
  month.

Section IWaste Determination
5
Solid Waste vs. Hazardous Waste

• Solid Waste A solid, semi-solid, liquid, sludge,
  or contained gas, that is no longer needed, to be
  discarded, or has served its useful purpose.
• Hazardous Waste A solid waste that is listed by
  the EPA or exhibits one or more of four
  characteristics.
• Ignitable Corrosive Reactive Toxic

6
Hazardous Waste is only a small portion of the
waste generated in the workplace, but by far the
most harmful to the nature and the environment.
7
Listed Hazardous Waste

• Complete lists of hazardous waste are located in
  your Chemical Hygiene Manual and with the Cluster
  Environmental Protection Specialists.

8
Hazardous Waste Determination

• A chemical waste may also be classified as
  hazardous if it exhibits one or more of the
  following characteristics
• Ignitability
• Corrosivity
• Reactivity
• Toxicity

9
Characteristic Hazardous Waste

• Ignitable Wastes
• Is a liquid with a flashpoint of 140F or below
  (alcohols containing less than 24 alcohol by
  volume are not considered ignitable) or,
• Is a flammable or ignitable compressed gas

10
Characteristic Hazardous Waste

• Corrosive Wastes
• Is an aqueous solution (a solution having more
  than 50 water) with a pH less than or equal to
  2.0 or greater than or equal to 12.5 or,
• A solid waste capable of corroding steel at
  specified conditions.

11
Characteristic Hazardous Waste

• Reactive Wastes
• Is normally unstable and readily undergoes
  violent change without detonating or,
• Reacts violently with water

12
Characteristic Hazardous Waste

• Toxic Wastes
• Using the Toxicity Characteristic Leaching
  Procedure the concentration of contaminants are
  equal to or greater than the regulatory levels
  identified in 40 CFR 261.24, Table 1. (or you can
  get the list from Kathie Moh)

13
Section IIWaste Minimization
14
What is Waste Minimization?

• Waste minimization includes source reduction
  practices that reduce or eliminate waste
  generation at the source and environmentally
  sound recycling practices, where source reduction
  is not economically practical.

15
Source Reduction

• includes any practice that reduces the quantity
  and/or toxicity of pollutants entering a waste
  stream prior to recycling, treatment, or
  disposal. 

16
Examples of Source Reduction

• equipment or technology modifications,
• reformulation or redesign of products,
• substitution of less toxic raw materials,
• improvements in work practices,
• maintenance,
• better inventory control.

17
Recycling

• includes the use, reuse and/or reclamation of
  waste residuals (that may be designated as a
  hazardous waste) or materials in a hazardous
  waste.

18
A material is used or reused

• if it is used as an ingredient in a process to
  make a product or, or if it is used as an
  effective substitute for a commercial product. 

19
A material is reclaimed

• if it is processed to recover a usable product,
  or if it is regenerated. 

20
How Can You Minimize Waste?

• Plan ahead
• Order only the amount needed
• Avoid storing excess chemicals
• Share unneeded chemicals
• Keep chemicals properly labeled

21
Why Minimize Waste?

• Reduce costs
• Increase process efficiency and productivity
• Reduce present and future regulatory burdens
• Improve workplace safety
• Improve environmental quality
• Maintain or improve institutional image

22
Section III How to Manage and Contain Waste
23
Satellite Accumulation Areas (SAA)

• All containers of hazardous waste must be stored
  in an area designated as a satellite accumulation
  area. Satellite accumulation areas must be
  established in the area where the waste was
  generated and under the direct control of the
  individual who generated the waste.

24
Accumulation Limits in SAAs

• A SAA may accumulate
• 55 gallons of non-acute waste
• Up to 1 quart of acutely hazardous waste
• There is no limit as to how long waste may be
  accumulated in each waste container in a SAA.
• However, once the container is full and/or the
  above stated limits are exceeded the waste must
  be removed from the work area within three
  working days.

25
Condition of Hazardous Waste Containers

• Containers must be in good condition,
• Have no rust, pinholes, dents, leaks, or chemical
  deposits on the outside,
• Container cap must be free of cracks and seals
  tightly no corks, stoppers, foil, and parafilm,
• Container can not leak if inverted no beakers,
  flasks, or coffee cans

26
Accumulation of Chemical Hazardous Waste

• Keep hazardous waste containers closed
• All containers of chemical
• hazardous waste must be
• closed at all times except
• when waste is being added
• or removed from the container.

27
Section IV How to Properly Dispose of Chemical
Wastes
28
Predisposal Procedures

• Sorted by compatibility
• In approved containers
• Tighten caps
• Ensure contents are properly identified

29
Example of a properly completed label

• These Cornell waste label forms are and only for
  chemical waste.
• Full names of the chemical components are listed
  along with the relative amounts
• Correct chemical type is checked
• All the contact information is complete

30
Disposal Procedures

• Move to a Satellite Accumulation Area (SAA)
• Once there are no more room in the SAA, move the
  waste to the storage cabinet in the
  shipping/receiving room, G-26.
• Give the copy of the Cornell waste label to
  Kathie Moh, or the CEPS or the CDSO officer

31
Youre Almost Done

• Make sure you fill out the quiz and drop it off
  in my mailbox for record keeping.
• Remember This is an annual requirement.
  
• SEE YOU NEXT YEAR
