Ala. Admin. Code r. 335-10-1-.02 - Definitions
For the purposes of this Chapter, the following words and phrases, unless a different meaning is plainly required by the context, shall have the following meanings:
(a)
"Activated sludge process plant" means a wastewater treatment plant employing a
biological wastewater treatment process in which a mixture of wastewater and a
coagulum or gel composed of bacteria and other microorganisms is agitated and
aerated in the presence of a sufficient concentration of dissolved oxygen so
that the gel can sorb dissolved and finely divided organic particles from the
wastewater. The gel or sludge is subsequently separated by sedimentation and is
wasted or returned to the aeration process as required. Activated sludge
consists of, but is not limited to, the following:
1. Conventional activated sludge;
2. Extended aeration;
3. Complete-mix aerated lagoon; and
4. Contact stabilization.
(b) "Advanced groundwater
treatment plant" means a water treatment plant employing any treatment of
greater technical sophistication than aeration, disinfection, corrosion
control, pressure filtration and fluoridation for the treatment of water from a
well or spring.
(c) "Basic
groundwater treatment plant" means a water treatment plant employing treatment
for corrosion control, disinfection, pressure filtration, slow sand filtration
and/or fluoridation for treatment of water from a well or spring.
(d) "Surface water treatment plant" means a
water treatment plant designed and operated for the treatment of surface water
supplies. This definition also includes treatment plants which have groundwater
under the influence of surface water as the source.
(e) "Certification" means the certificate of
competency issued by the Director stating that the operator has met the
requirements for the specified operator classification of the certification
program.
(f) "Department" means the
Alabama Department of Environmental Management established by Code
of Ala. 1975, §
22-22A-4.
(g) "Director" means the Director of the
Alabama Department of Environmental Management, appointed pursuant to
Code of Ala. 1975, §
22-22A-4.
(h) "Operator" means the person on duty who
has direct responsibility for the operation of a water treatment plant, water
distribution system, public wastewater collection system or wastewater
treatment plant. A person shall be deemed to have direct responsibility for the
operation of a water treatment plant, water distribution system or wastewater
treatment plant if he in fact supervises or directs the operation of a water
treatment plant, water distribution system or wastewater treatment plant, or
makes process control decisions.
(i) "Operator intern" means a person who has
successfully passed the operator examination but has not yet obtained the
necessary experience to become certified.
(j) "Person" means a natural
person.
(k) "Process control
decision" means a decision regarding the daily operational activities of a
water system or wastewater system that will directly impact the quality and/or
quantity of drinking water or treated wastewater.
(l) "Public wastewater collection system"
means the system of pipes, structures, and facilities through which wastewater,
municipal sewage, or wastes, of a liquid nature is received, collected, stored,
transported, or delivered into a wastewater treatment plant.
(m) "Restricted certificate" means an
operator certificate issued without examination which is valid only for a
particular plant or system and cannot be transferred to another
plant.
(n) "Trickling filter and/or
biological contactor process plant" means a wastewater treatment plant
employing a treatment process whereby the wastewater is passed over a medium
upon which grows bacteria and other microorganisms that sorb and oxidize
soluble and finely dissolved organic matter. Subsequent sedimentation separates
the resulting settleable solids from the process effluent.
(o) "Wastewater treatment lagoon" means a
wastewater treatment plant employing an excavation designed and constructed to
receive raw or pretreated wastewater in which stabilization is accomplished by
several natural and photosynthetic (algal) self-purification phenomena with or
without supplemental aeration. Wastewater treatment lagoon consists of, but is
not limited to the following:
1.
Non-aerated;
2. Partial
mix;
3. Hydrograph control release
(HCR);
4. Aquaculture and
constructed wetlands.
(p) "Wastewater treatment plant" means the
facility or group of units used for the treatment of wastewater from public
wastewater collection systems and for the reduction or handling of solids
removed from such wastewater.
(q)
"Water distribution system" means that portion of the water supply system in
which water is conveyed from the water treatment plant or other supply point to
the premises of the consumer.
(r)
"Water treatment plant" means that portion of the water supply system which in
some way alters the physical, chemical or bacteriological quality of the
water.
(s) "Water supply system"
means the system of pipes, structures and facilities through which a public
water supply is obtained, treated and sold or distributed for human consumption
for household use and which serves at least 15 service connections used by
year-round residents or regularly serves at least 25 year-round
residents.
(t) "Working experience"
means experience that is gained from actual hands-on operation of a water or
wastewater treatment plant, water distribution system or public wastewater
collection system. Excluded from this definition is work of a clerical or
administrative nature.
