**Notes:**
Title Slide.  Picture of BARC West Campus.

## 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.

**Notes:**
It’s all of ours responsibility to mange our waste in an environmentally sound way.

## 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 IWaste Determination

**Notes:**
The first section in on Waste Determination.

## 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

**Notes:**
Definitions of Solid Waste and Hazardous Waste according to the Resource Conservation and Recovery Act.

## 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.

**Notes:**
Hazardous waste is a very small portion of waste generated, but the portion that can do the most harm to the environment.

## Listed Hazardous Waste

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

**Notes:**
Page from the Chemical Waste Training Manual showing listed hazardous waste.

## 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

**Notes:**
Determining hazardous waste by characteristics identified in Title 40, Code of Federal Regulations, Section 261.20 thru 261.24.

## Characteristic Hazardous Waste

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

**Notes:**
First Characteristic, Ignitable Waste.  Waste with a flash point of 140 degrees Fahrenheit or below as identified on a Material Safety Data Sheet.

## 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.

**Notes:**
Second Characteristic, Corrosive Waste.  A waste with a pH less than or equal to 2.0 or greater than or equal to 12.5 as identified on a Material Safety Data Sheet. 

## Characteristic Hazardous Waste

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

**Notes:**
Third characteristic, Reactive Waste.  A waste that reacts violently with water as identified on a Material Safety Data Sheet.

## 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)

**Notes:**
Fourth and final characteristic, Toxic Waste.  A waste that exceeds the regulatory limits identified in 40 Code of Federal Regulation, Section 261.24, Table 1.

## Section IIWaste Minimization

**Notes:**
The second section is on Waste Minimization.

## 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.**

**Notes:**
The Environmental Protection Agency’s definition of Waste Minimization.

## Source Reduction

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

**Notes:**
How the EPA defines Source Reduction.

## 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.

**Notes:**
Some examples of Source Reduction.

## 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.

**Notes:**
The EPA’s definition of Recycling.

## 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.

**Notes:**
Under Recycling, what is considered Used or Reused.

## A material is “reclaimed”

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

**Notes:**
Under Recycling what is considered Reclaimed.

## How Can “You” Minimize Waste?

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

**Notes:**
Ways we can minimize waste in the laboratories.

## 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

**Notes:**
Examples of why we need to minimize wastes.

## Section III How to Manage and Contain Waste 

**Notes:**
Section three is on How to Manage and Contain Wastes.

## 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.

**Notes:**
Rule of thumb for Satellite Accumulation Areas.

## Accumulation Limits in SAA’s

- 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.

**Notes:**
Parameters for accumulation in a Satellite Accumulation Area.

## 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**

**Notes:**
Containers allowable to be used to accumulate hazardous waste.  Picture of containers that can not be used to hold hazardous waste.

## 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.

**Notes:**
All containers that hold hazardous waste must be kept closed, except for when waste is being added or removed.  Picture of container holding a funnel.  The container can not be stored like this.

## Section IV How to Properly Dispose of Chemical Wastes 

**Notes:**
The forth section is on How to Properly Dispose of Chemical Wastes at the Beltsville Area.

## Predisposal Procedures

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

**Notes:**
How to make containers ready for pickup.

## 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

## 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

**Notes:**
What to do when you are ready to have the waste picked up.  Picture of a BA Form 513.
