NPDES: waste water correct answers Any waste water the discharge from a facility is covered
under the clean water act
in general municipalities of constructed collection systems to convey waste water from the
discharge going to a centralized treatment facility
once at the treatment plan to waste water is clean such that it can be discharged to surface waters
without degrading surface water quality sanitary waste, as well as industrial waste or carry
through the conveyance system to the plant
to discharge to waste water treatment plant you need an NPDES permit
The owner of the treatment plan specifies what discharges it can except else its plant, I just want
requirements getting much more stringent and federal or state requirements
The POTW set a timer based on the type of treatment they selected for their plant and the limits
they need to meet for discharge the surface water or pass back up the line to dischargers
NPDES: industrial pre-treatment correct answers Many facilities cannot beat the discharge limits
for their industrial waste
Pre-treatment is then required
Many facilities have wastewater treatment facilities on site to ensure that their discharges meet
their permit limits
Categorical industrial users correct answers TCEQ requires 128 of the municipal discharge
permits to maintain a pre-treatment program to control industrial waste water discharges
Under federal law 21 categories of industries must pre-treat their waist to best available
technology before discharge in West Republic waste water treatment plant
Examples: Electroplating, grain mills, iron and steel, battery manufacturing, paving and roofing,
soap and detergent manufacturing, metal finishing, leather tanning and finishing
CWA: surface water correct answers Classifies surface water (rivers, streams, bays, gulfs, etc.)
Classifies uses of surface water (a drinking supply, recreation, aquatic life and habitat, etc.)
Classifies contact with surface water
Protects sole source drinking drinking supplies
, Sets flow conditions, mixing zones, lab and analytical requirements for sampling
Surface water quality: attainable use correct answers Are used to could be reasonably achieved
by body body of water in accordance with its physical, biological, and chemical characteristics
whether it is currently meeting that use or not
Surface water quality: designated use correct answers Are use that as a sign to a specific water
bodies, typical uses that may be designated for specific water bottles include domestic water
supply, categories of aquatic life use, recreation categories, and aquifer protection
Surface water quality: existing use correct answers A use that is currently being supported by
specific water body or that was attained on or after November 28, 1975
Surface water quality: presumed use correct answers Are used it as a sign to generic categories of
water bodies, they are superseded by designated uses for individual water bodies
Surface water quality: noncontact recreation correct answers Activities that do not involve a
significant risk of water ingestion, such as those with limited body contact incidental to
Shoreline activity, including burden, hiking, and biking. Noncontact recreation use may also be
assigned were primary and secondary contact recreation activities should not occur because of
unsafe conditions, such as a ship and barge traffic
Surface water quality: primary contact recreation correct answers Activities that are presume to
involve a significant risk of ingestion of water (E.G. wading by children, swimming, water
skiing, diving, tubing, surfing, and the following white water activities: kayaking, canoeing, and
rafting)
Surface water quality: secondary contact recreation correct answers Activities the commonly
occur but have a limited body contact incidental to show an activity (E.G.fishing, canoeing,
kayaking, rafting, and motorboating) these activities are presumed to pose a less significant risk
of water ingestion than primary contact recreation
Surface water quality: background correct answers Refers to the water quality in a particular
water body that would occur if the water body were relatively unaffected by human activities
Surface water quality: Critical low flow correct answers Low flow condition that consists of the
seven day, two-year low flow or the alternate low flows for springfed systems as discussed and
below which some standards Do not apply
Surface water quality: Dry weather flows correct answers Sustained or typicalDry, warm weather
flaws between rainfall events, excluding unusual antecedent conditions of drought or wet
weather
