AND CORRECT ANSWERS
GRADED A+ 2025-2026
P2 - ANS-Pollution Prevention, the highest priority is source reduction, the most
effective P2 activity is product modification to avoid solvent use
PDCA - ANS-Plan, Do, Check, Act (P2)
HAP - ANS-Hazardous Air Pollutant
MACT - ANS-Maximum Achievable Control Technology
TSDF - ANS-Transport, Storage, Disposal Facility, is required to have a waste tracking
program, a training plan, arrangements with emergency responders, an employee
onsite at all times
NPDES - ANS-National Pollution Discharge Elimination System
SWPPPs - ANS-Stormwater pollution prevention plans
Waste Management Hierarchy - ANS-1. Prevent or reduce 2. Recycle 3. Treat 4. Dispose
or otherwise release
AEA - ANS-Atomic Energy Act
,RCRA - ANS-Resource Conservation and Recovery Act, covers generation of haz waste,
transportation of haz waste, USTs, and non-haz solid waste
ALARA - ANS-As Low As Reasonably Achievable (AEA)
LDRs - ANS-Land Disposal Restriction (RCRA), meant to minimize post-closure escape
of waste, reduces the volume of haz waste disposal, encourages recycling
MTRs - ANS-Minimum Technology Requirements (RCRA), including liner requirements,
leak detection and collection requirements, groundwater monitoring
CAMU - ANS-Corrective Action Management Unit (RCRA), needs to assess
environmental and health risks, if it will enhance the timeliness of remediation, will
minimize the land utilized for final disposal, will provide expeditious implementation
of site remedies
TU - ANS-Temporary Unit (RCRA)
RI - ANS-Remedial Investigation
CMS - ANS-Corrective Measures Study (RCRA)
IM - ANS-Interim Measures
RFI - ANS-RCRA Facility Investigation
SWMU - ANS-Solid Waste Management Unit (RCRA)
HSWA - ANS-Hazardous and Solid Waste Amendments (expanded RCRA)
CA - ANS-Corrective Action (HSWA), requires identification of all SWMUs on a site
before issuance of a Part B permit, a comprehensive groundwater monitoring program,
, can require clean-ups outside a facilities boundary, provide for temporary treatment
units, has an additional section in a final permit requiring further site clean-ups
Used Oil - ANS-Arsenic (5 ppm max), Cadmium (2 ppm max), Chromium (10ppm max),
Lead (100 ppm max), Total Halogens (4000 ppm max), Flash point (100oF minimum)
NIOSH - ANS-National Institute of Occupational Safety and Health, conducts research in
occupational safety and health, develop criteria as a basis for new standards, provides
education, manpower development and training on health and safety equipment,
enforces occupational health and safety guidelines.
TLV - ANS-Threshold Limit Value
Ceiling Value - ANS-An absolute value which cannot be exceeded (no TWA)
Nucleus - ANS-The center of an atom made up of a proton and a neutron
Ionization - ANS-the removal of electrons from an electrically neutral atom
TDS - ANS-Time, Distance, Shielding (ways to reduce exposure to radiation)
Alpha particle - ANS-Slowest, largest radioactive particle. Most destructive if inhaled or
ingested. Can be stopped by paper/tyvek. Made up of a proton and neutron.
Beta particle - ANS-Can be stopped by plastic/aluminum foil. Can travel up to four feet
from source. Made up of an electron.
Half-lives to get to 12.5% of original radionuclide - ANS-Three. 100 (one) 50 (two) 25
(three) 12.5
Toxin - ANS-any substance that will produce a harmful effect when introduced to the
body in sufficient concentrations, creates a toxic effect when a mechanism is available
to allow a biochemical reaction at a receptor site in the target organ
