effects as stated under the general conditions in Subsection A and/or
does not conform to the limitations set forth under the specific conditions
in Subsection B.
A.
General conditions. Waste shall be prohibited if it:
(1)
Places unusual demands on the wastewater treatment process or upon
the wastewater treatment plant equipment.
(2)
Limits or reduces the normal effectiveness and efficiency of the
wastewater treatment process.
(3)
Contains toxics or other pollutants in amounts or concentrations
that endanger public health and safety and the physical integrity
of the system.
(4)
Has obnoxious conditions inimical to the public interest.
(5)
Causes a chemical reaction, either directly or indirectly, with the
materials of construction which impairs the strength and durability
of wastewater lines and treatment plant structures.
(6)
Causes mechanical action which will destroy or damage wastewater
lines or plant structures.
(7)
Restricts the hydraulic capacity of sewer lines and plant facilities.
(8)
Restricts the normal inspection or maintenance of sewer lines or
sewer structures.
(9)
Contains toxics or other pollutants in amounts or concentrations
that cause a violation of effluent or water quality limitations.
(10)
Contains toxins or other pollutants in amounts or concentrations
that would preclude the selection of the most cost effective alternative
for wastewater treatment and/or sludge disposal.
B.
Special conditions. The following standards shall control the quantity
and quality of wastewater which may be discharged through a connection
into the system.

system user, as required by the Borough. Where necessary, detention
tanks may be required to reduce the maximum rate of discharge to such
percentage of the average twenty-four-hour rate of discharge as directed.
(3)
The pH of all wastewater shall be maintained between the limits of
pH 7.0 to pH 8.0 based upon a daily average or composite flow, with
a maximum temporary variation between the limits of pH 5.5 to pH 8.5.
(4)
The temperature of wastewater upon discharge shall be within the
limits of 32° F. to 150° F.
(5)
The wastewater must not contain more than two parts per million of
the following gases: hydrogen sulfide, sulfur dioxide, nitrous oxide
or any of the halogens.
(6)
The color of wastewater shall not be different than typical domestic
wastewater.
(7)
The limiting chemical characteristics of receivable wastewater shall
be as follows:
(a)
BOD5: a monthly average of 250 milligrams
per liter and a maximum daily average of 375 milligrams per liter.
(b)
Suspended solids: a monthly average of 250 milligrams per liter
and a maximum daily average of 375 milligrams per liter.
(c)
Settleable solids (Imhoff cone test, one hour): 10 milliliters
(maximum).
(d)
Total kjeldahl nitrogen: a monthly average of 45 milligrams
per liter and a maximum daily average of 67.5 milligrams per liter.
(e)
Total phosphorus: a monthly average of 10 milligrams per liter
and a maximum daily average of 15 milligrams per liter.
(f)
Total dissolved solids: a monthly average of 1,500 milligrams
per liter and a maximum daily average of 2,000 milligrams per liter.
(g)
Oil and grease: a monthly average of 100 milligrams per liter
and a maximum daily average of 150 milligrams per liter.
(h)
Surfactants: a monthly average of 20 milligrams per liter and
a maximum daily average of 30 milligrams per liter as determined by
the methylene blue active substances (MBAS) test.
(8)
The wastewater shall not contain phenols in excess of 0.20 milligrams
per liter at any time.
(9)
The wastewater shall not contain any toxic materials dangerous to
humans, animals, aquatic or stream life or which adversely affect
the biological functions and operations of the sewage treatment plant
facilities.
(10)
The wastewater shall not contain more than 100 milligrams per
liter of any antiseptic substance at any time.
(11)
The wastewater shall contain no gases or vapors, either free
or occluded, in concentrations toxic or dangerous to humans, animals,
aquatic or stream life.
(12)
The wastewater shall not contain sulfides exceeding 2.0 milligrams
per liter at any time.
(13)
The wastewater shall contain no poisons or radioactive materials
in sufficient quantities to endanger humans or interfere with biological
