RATIONALES CALIFORNIA QAL QAC
STUDY GUIDE
An organism microscopic size, such as a bacterium, virus, fungus, or algae.
- CORRECT ANSWER-Microorganism
Used to express the design flow capacity or actual flow of a waste water
treatment facility - CORRECT ANSWER-Millions of gallons per day -
(MGD)
A contact pesticide which has a localized pesticidal affect; not transported
through the plant or animal tissues - CORRECT ANSWER-Non-systemic
An undesirable discharge of sanitary or combined sewer flow into a river,
scream, or other surface water. - CORRECT ANSWER-Overflow
NOT the same as vapor or gas. Microscopic particles of solid or liquid
matter suspended in the air. - CORRECT ANSWER-Particulate
Stricter requirements than those on the pesticides labeling or in California
law and regulation. Permit conditions are issued by the county agricultural
,commissioner and must be followed. - CORRECT ANSWER-Permit
conditions
This document describes any actions or events that occurred during the
fumigation that differed from the fumigation management plan,
measurements like humidity for example taken to comply with good
agricultural practices (GAPs), if not recorded in the FMP, the national
weather service forecast during application 48 hours following application,
and any incidents or complaints - CORRECT ANSWER-Post application
summary
Any pesticide that, for a reasonable length of time, is effective in preventing
the development and activity of wood rotting fungi, bars of various kinds,
and harmful insects that deteriorate wood. - CORRECT ANSWER-
Preservative
A method of vacuum chamber fumigation where the pressure is lowered,
fumigant introduced and then pressure is restored. This is called "below
NAP " (normal atmospheric pressure). - CORRECT ANSWER-Restored
pressure fumigation
A permit issued by the county agricultural commissioner to authorize
certified applicators to purchase, possess, and use California restricted
materials - CORRECT ANSWER-Restricted materials permit

, The soft outer layers of recently formed wood between the heartwood and
the bark, containing the functioning vascular tissue. - CORRECT
ANSWER-Sapwood
A type of decay developing under very wet conditions (as in cooling towers
in boat timbers) in the outer wood layers. It is caused by cellulose
destroying micro fungi that attacked the secondary cell walls but not the
intercellular layer. - CORRECT ANSWER-Soft rot
The ability of a substance to dissolve in another substance (e.g., salt in
water) - CORRECT ANSWER-Solubility
A physical and chemical process by which one substance becomes attached
to another. The term covers both absorption and adsorption - CORRECT
ANSWER-Sorption
The ratio of the density of any substance to the density of some other
substance taken as standard, water being the standard for liquids and
solids, and hydrogen or air being the standard for gases. - CORRECT
ANSWER-Specific gravity
A reproductive structure produced by some plants and micro organisms
that is resistant to environmental influences. - CORRECT ANSWER-
Spores
Volume of a simple structure - CORRECT ANSWER-Length X width X
height
