2.  Hazardous waste facilities store
and dispose of toxic materials
 Hazardous waste must be
transported, contained, treated or
disposed of with extreme care
and according to specific
guidelines and procedures

3. Transport /Storage/Disposal Facility -Requirements
 Secure a TSD Facility Permit ;
 Pollution Control Officer(PCO)/Environmental
Officer;
 Comply with the waste acceptance
requirements and the Manifest System;
 Provide initial wastes acceptance procedure to
ensure that the TSD facility shall not accept
wastes beyond its capacity (including quantity
and quality);
 Submit residuals management plan including
results of analysis of all hazardous wastes
treated, recycled and recovered;

4.  Conduct period inspection of the TSD
facility in order to maintain proper function;
 Prepare and implement an emergency
contingency plan;
 Train its personnel and staff on the
implementation of the emergency
contingency plan and the hazard posed by
improper handling, transport, and use of
chemical substances and their containers;
and
 Submit a quarterly report on operation
practices of the TSD facility to the EMB
Central Office

5. Is typically the result of a spill or
accident during the production, or
use of, radionuclide (Radioisotopes);
these have unstable nuclei which are
subject to radioactive decay

6. Distribution of Radioactive
contamination by nuclear explosion.
The amount of radioactive material
released in an accident is called
source term.

9. Has also more specific meanings in science:
 In chemistry, the term usually describes a single
constituent, but in specialized fields the term can also
mean chemical mixtures, even up to the level of cellular
materials. All chemicals contain some level of impurity.
 In environmental chemistry the term is in some cases
virtually equivalent to pollution, where the main interest
is the harm done on a large scale to humans or to
organisms or environments that are important to
humans.
 In radiation protection the radioactive contamination is
radioactive substances on surfaces, or within solids,
liquids or gases (including the human body), where
their presence is unintended or undesirable, or the
process giving rise to their presence in such places.

11.  “Containment” is different from
“contaminated”
 the act, process, or means of keeping
something within limits
 the policy, process, or result of preventing
the expansion of a hostile power or
ideology
 (in a nuclear power plant) an enclosure
completely surrounding a nuclear reactor,
designed to prevent the release of
radioactive material in the event of an
accident.

12. Radioactive contamination may exist
on surfaces or in volumes of material
or air

13.  May either be FIXED or REMOVABLE(Free)
 “Fixed” Cannot be spread but it is still
measurable
 “Removable” contamination there is the
hazard of contamination spread to other
surfaces such as skin or clothing, or
entrainment in the air.
 Dirt that contains radioactive materials
 Sources: Spills, leaks or residue from
mechanical grinding

17.  The most common form of disposing of
hazardous waste occur at land disposal
sites such as landfills, waste piles, land
treatment units or surface impoundments
 “To permanently contain the waste and
prevent the release of harmful pollutants to
the environment” EPA

20. Holding hazardous waste for a
temporary period, after which the
hazardous waste is treated, disposed
of, or stored elsewhere
