Answer:

Explanation:

vPoint Source - a source of water discharged to surface water through a discrete point - generally through a pipe, ditch, or channel.

Nonpoint Source - Nonpoint sources, such as parking lots or athletic fields, discharge runoff water to groundwater or surface water; runoff does not come from  a pipe, ditch, or channel. These sources may contain pollutants such as pesticides, motor oil, and soaps.

Navigable Waters of the United States  For the purposes of the Clean Water Act, the term "navigable waters" includes:

all waters used in commerce, including groundwater;

all interstate waters including wetlands, mudflats, and sand-flats; and

all other waters such as lakes, rivers, streams, wetlands and sloughs.

EPA policy states, "The majority of facilities in the U.S. have the potential to discharge to navigable waters."  The Supreme Court decision in (2006) requires the Army Corps of Engineers and the EPA to determine whether there is a "significant nexus" between a navigable waterway and an area a spill might affect.  In June of 2007, EPA and the Army Corps of Engineers released provisional interpretive guidance regarding the "significant nexus” question. According to this guidance, the agencies will assert jurisdiction over traditional navigable waters, wetlands adjacent thereto, and relatively permanent tributaries thereof. The agencies will generally not assert jurisdiction over swales and ditches that lack routine water flow. Finally, the agencies will apply the "significant nexus" requirement and make a case-by-case, fact-specific analysis on impermanent tributaries and other wetlands.

Additional executive orders were issued 2015 in 2019.  Under the 2019 proposal, traditional navigable waters, tributaries to those waters, certain ditches, certain lakes and ponds, impoundments of jurisdictional waters, and wetlands adjacent to jurisdictional waters would be federally regulated. It also details what are not "waters of the United States," such as features that only contain water during or in response to rainfall (e.g., ephemeral features); groundwater; many ditches, including most roadside or farm ditches; prior converted cropland; stormwater control features; and waste treatment systems.

Could the requirement for one or more NPDES Discharge Permit apply to my campus?

If your campus discharges pollutants directly to navigable waters of the United States through a point source, you must obtain an NPDES permit or redirect the flow of the waste.

Stormwater releases from certain activities require an NPDES permit. The most common activities on college campuses requiring NPDES permits for stormwater are construction activities disturbing more than 1 acre, hazardous waste storage areas operating under the Resource Conservation and Recovery Act permit system, steam-generating power plants, and airports. See Stormwater section below.

Regulations issued by local water authorities, or Publicly Owned Treatment Works (POTWs), not NPDES permits, govern discharges into sanitary sewer systems. See Sewer Use (POTW) section below for more information about requirements for using POTWs for commercial or industrial waste disposal.

What do I have to do related to NPDES Discharge Permits?

Determine where wastewater flows from buildings and processes on your campus. Any industrial or commercial operation (e.g., ice rink melt pits, floor drains, and vehicle wash stations) that discharge into a water of the United States may require an NPDES permit. If required, you must obtain such a permit from the appropriate regulatory agency, probably your state environmental agency.

French drains, dry wells, and septic system leach fields are different from point source discharges because they do not immediately affect surface water. Some state and federal environmental agencies manage these systems under the Underground Injection Control program, part of the Safe Drinking Water Act. See Safe Drinking Water Act for more information.

Strict liability is a legal concept that holds individuals or entities responsible for damages or injuries caused by their actions or products, regardless of their level of intent or fault. Construction projects are not subject to strict liability.

According to the law, regardless of their level of guilt or intention, strict liability holds people and organisations accountable for any losses or harms brought on by their behaviours or products. The other choices mentioned, including owners of trespassing cattle and keepers of naturally dangerous wild animals are all instances of products or activities that, depending on the situation, may be subject to strict responsibility. Construction projects are not, however, inherently hazardous or flawed, and any responsibility for injuries or damages would normally be established based on elements like negligence or contract breach.

Attention-deficit/hyperactivity disorder (ADHD) is one of the most common neurodevelopmental disorders affecting children. ADHD is characterized by different behaviors that include one or more of the following symptoms: inattention (poor concentration), impulsivity (interrupting behavior) and hyperactivity (state abnormally active). It has been reported that DHD diagnoses in children between 4 and 17 years of age dramatically increased from 6 percent (6%) during the period 1997-1998 to 10 percent (10%) during the period 2015-2016. Although the causes of this increase have not been established, the American Psychiatric Association (APA) indicates that the increase might be due to the increased access of communities historically relegated to receive care and decreased stigma to be diagnosed with ADHD. Other possible causes range from chemical factors to unhealthy habits during pregnancy (e.g., smoking, substance abuse, poor nutrition). On the other hand, it has also been proposed that this increase may be as a result that ​ADHD is often misdiagnosed and confused with other conditions (e.g., bipolar disorder, autism, kids being kids, etc).

In the process of sexual reproduction, mating of male gamete and female gamete is required for the fertilization to take place in humans.

A gamete is an animal or plant reproductive cell. Male gametes in animals are known as sperm, while female gametes are known as ova or egg cells.

Fertilization is the process in which a woman's egg combines with a man's sperm to form an embryo.

Usually, the fallopian tube that connects an ovary to the uterus is where fertilization occurs. An embryo begins to develop if the fertilized egg successfully passes through the fallopian tube and implants in the uterus.
