The owner of any house, building or property which is used for commercial,
industrial and/or residential purposes abutting on any street, alley or right-of-way
in which there is or may be located a gravity sewer connected to the treatment
works of the PSA is required, at the owner's expense, to install suitable
toilet facilities therein and to connect such facilities directly to the proper
sewer in accordance with the provisions of this chapter within 30 days after
notice that a sewer is available within 300 feet of the property line. This
section shall not apply to any person served by a privately constructed, owned,
operated and maintained sewer and treatment facility which discharges directly
to a natural outlet in accordance with the provisions of this chapter and
applicable state and federal laws.
A.
No person shall uncover, make any connections with, use,
alter or disturb any wastewater sewer without first obtaining a written permit
from the Executive Director.
C.
In all cases, the owner shall make application for a
permit to connect to the PSA's treatment works on a form furnished by
the PSA. The permit application shall be supplemented by wastewater information
required to administer this chapter. A permit and inspection fee in an amount
set by the PSA from time to time in accordance with the applicable laws and
regulations shall be paid to the PSA at the time the application is filed.
Existing building sewers may be used for connection of new buildings
only when they are found, on examination and testing by the Executive Director,
to meet the requirements of this chapter.
A.
No person shall connect roof, foundation, areaway, parking lot, roadway or other surface runoff or groundwater drains to any sewer which is connected to a treatment works unless such connection is authorized, in writing, by the Executive Director. The connection of such drains shall conform to codes specified in § 73-10 or as specified by the Executive Director as a condition of approval of such connection.
B.
Except as provided above, roof, foundation, areaway,
parking lot, roadway or other surface runoff or groundwater drains shall discharge
to natural outlets or storm sewers.
The connection of a building sewer into a treatment works shall conform
to the requirements of the Building and Plumbing Codes or other applicable
requirements of the PSA or the procedures set forth in appropriate specifications
of the Commonwealth of Virginia Sewerage Regulations, the Uniform Building
Code of Virginia and the American Society of Testing Materials. The connections
shall be made gastight and watertight and shall be verified by proper testing.
Any deviation from the prescribed procedures and materials must be approved,
in writing, by the Executive Director before installation.
The applicant for a building sewer or other drainage connection permit
shall notify the Executive Director when such sewer or drainage connection
is ready for inspection prior to its connection to the PSA's treatment
works. Such connection inspections and testing, as deemed necessary by the
Executive Director, shall be made by the Executive Director.
A.
No industrial user shall introduce or cause to be introduced
into the POTW any pollutant or wastewater which causes pass-through or interference.
These general prohibitions apply to all industrial users of the POTW, whether
or not they are subject to categorical pretreatment standards or any other
federal, state or local pretreatment standards or requirements. Furthermore,
no industrial user may contribute the following substances to the POTW:
(1)
Pollutants which create a fire or explosive hazard in
the municipal wastewater collection system and POTW, including but not limited
to waste streams with a closed-cup flash point of less than 140° F. (60°
C.) using the test methods specified in 40 CFR 261.21.
(2)
Any wastewater having a pH less than 5.0 or otherwise
causing corrosive structural damage to the POTW or equipment or endangering
PSA personnel.
(3)
Solid or viscous substances in amounts which will cause
obstruction of the flow in the POTW, resulting in interference, but in no
case solids greater than three inches or eight centimeters in any dimension.
(4)
Any wastewater containing pollutants, including oxygen-demanding
pollutants (BOD, etc.), released in a discharge at a flow rate and/or pollutant
concentration which, either singularly or by interaction with other pollutants,
will cause interference with either the POTW or any wastewater treatment or
sludge process or which will constitute a hazard to humans or animals.
(5)
Any wastewater having a temperature greater than 120°
F. or which will inhibit biological activity in the treatment plant, resulting
in interference, but in no case wastewater which causes the temperature at
the introduction into the treatment plant to exceed 104° F. (40° C.).
(6)
Petroleum oil, nonbiodegradable cutting oil or products
of mineral oil origin in amounts that will cause interference or pass-through.
(7)
Any pollutants which result in the presence of toxic
gases, vapors or fumes within the POTW in a quantity that may cause acute
worker health and safety problems.
(8)
Any trucked or hauled pollutants, except at discharge
points designated by the PSA.
[Amended 4-7-1997]
(9)
Any noxious or malodorous liquids, gases, solids or other
wastewater which, either singularly or by interaction with other wastes, is
sufficient to create a public nuisance, a hazard to life, or to prevent entry
into the sewers for maintenance and repair.
(10)
Any wastewater which imparts color which cannot be removed
by the treatment process, such as, but not limited to, dye wastes and vegetable
tanning solutions, which consequently imparts color to the treatment plant's
effluent, thereby violating the PSA's VPDES permit. Color (in combination
with turbidity) shall not cause the treatment plant effluent to reduce the
depth of the compensation point for photosynthetic activity by more than 10%
from the seasonably established norm for aquatic life.
(11)
Any wastewater containing any radioactive wastes or isotopes,
except as specifically approved by the Executive Director in compliance with
applicable state or federal regulations.
(12)
Stormwater, surface water, groundwater, artesian well
water, roof runoff, subsurface drainage, swimming pool drainage, condensate,
deionized water, noncontact cooling water and unpolluted industrial wastewater,
unless specifically authorized by the Executive Director.
(13)
Any sludge, screenings or other residues from the pretreatment
of industrial wastes.
(14)
Any medical wastes, except as specifically authorized
by the Executive Director in a wastewater discharge permit.
(15)
Any wastewater causing the treatment plant's effluent
to fail a toxicity test in accordance Regulation VR 680-21-00 of the Virginia
Water Quality Standards or any amendments or replacements thereof.
(16)
Any wastes containing detergents, surface active agents
or other substances which may cause excessive foaming in the POTW.
(17)
Any discharge of fats, oils or greases of animal or vegetable
origin is limited to 100 milligrams per liter or some lesser limit which may
be placed in a permit at the discretion of the Executive Director.
(18)
Any discharge of petroleum or hydrocarbon products is
limited to 20 milligrams per liter or some lesser limit which may be placed
in a permit at the discretion of the Executive Director.
B.
Wastes prohibited by this section shall not be processed
or stored in such a manner that they could be discharged to the POTW. All
floor drains located in process or materials storage areas must discharge
to the industrial user's pretreatment facility before connecting with
the POTW.
The national categorical pretreatment standards found at 40 CFR Chapter
I, Subchapter N, Parts 405-471 are hereby incorporated.
State pretreatment standards in the Virginia Sewerage Regulations promulgated
by the State Department of Health and the State Water Control Board are hereby
incorporated.
A.
The charges and fees for service are those fees established
by the rate ordinance heretofore enacted by the PSA and any amendments or
changes in said rate ordinance which may hereinafter be enacted by the PSA.
B.
Surcharge.

NOTE: The above formulas reflect the current estimated operation and
maintenance costs for treatment per pound of BOD and SS at the POTW. The factors
affecting such costs may be reviewed by the Sanitary Board and the above formulas
revised to reflect revised operation and maintenance costs as required.

A.
Each industrial user, unless otherwise excluded, shall
be required to pay an industrial cost recovery charge in addition to their
user charge and/or surcharge in accordance with United States Environmental
Protection Agency requirements. Unless otherwise excluded, each industrial
user's industrial cost recovery charge shall be computed based on the
treatment facility servicing the industry and the following parameters:
|
Where
| ||||
|
Q
|
=
|
Average daily wastewater flow contributed by the user in gallons per
day.
| ||
|
BOD
|
=
|
The average daily poundage of five-day biochemical oxygen demand contributed
by a user, which shall be calculated as follows:
| ||
|
Q x BOD5 x 8.31
| ||||
|
Where
| ||||
|
Q is in the form of million gallons per day.
| ||||
|
BOD5 is in the form of milligrams per liter.
| ||||
|
SS
|
=
|
The average daily poundage of suspended solids contributed by a user,
which shall be calculated as follows:
| ||
|
Q x SS x 8.34.
| ||||
|
Where
| ||||
|
Q is in the form of million gallons per day.
| ||||
|
SS is in the form of milligrams per liter.
| ||||
|
Sample industrial recovery calculation assumed parameters are:
| ||||
|
Q
|
=
|
150,000 gallons per day.
| ||
|
BOD
|
=
|
180 milligrams per liter.
| ||
|
SS
|
=
|
200 milligrams per liter.
| ||
|
BOD calculation:
| ||||
|
0.15 million gallons per day x 180 milligrams per liter x 8.34 = 225.18
pounds per day.
| ||||
|
SS calculation:
| ||||
|
0.15 million gallons per day x 20 milligrams per liter x 8.34 = 250.20
pounds per day.
| ||||
|
Therefore:

BOD
|
=

B.
The requirements for exclusion from the above charges
are as follows: industrial users [as defined in 40 CFR 35.905-8(a), (b), (c),
(d) and (e), which discharge only nonprocessed, segregated, domestic waste
or waste from sanitary conveniences (for example, the so-called "dry" industries)]
which are not significant industrial users under the regulations (40 CFR 35.925-12).
The Board of the PSA reserves the right to establish, by ordinance or in wastewater discharge permits, more stringent standards or requirements on discharges to the POTW if deemed necessary to comply with the objectives presented in § 73-1 of this chapter or the general and specific prohibitions in § 73-12 of this chapter.
A.
The PSA reserves the right to enter into special agreements
with industrial users setting out special terms under which they may discharge
to the POTW. In no case will a special agreement waive compliance with a pretreatment
standard or requirement. However, the industrial user may request a net gross
adjustment to a categorical standard in accordance with 40 CFR 403-15. The
industrial user may also request a variance from the categorical pretreatment
standard from the EPA. Such a request will be approved only if the industrial
user can prove that factors relating to its discharge are fundamentally different
from the factors considered by the EPA when establishing that pretreatment
standard. An industrial user requesting a fundamentally different factor variance
must comply with the procedural and substantive provisions in 40 CFR 403.13.
B.
Nothing in this article shall be construed as preventing
any agreement or arrangement between the PSA and any user of the treatment
works and treatment facility whereby wastewater of unusual strength or character
(only in terms of BOD and/or suspended solids) is accepted into the system
and specially treated subject to additional payments or user charges as may
be applicable.
No industrial user shall ever increase the use of process water or in
any way attempt to dilute a discharge as a partial or complete substitute
for adequate treatment to achieve compliance with a discharge limitation unless
expressly authorized by an applicable pretreatment standard or requirement.
The Executive Director may impose mass limitations on industrial users which
are using dilution to meet applicable pretreatment standards or requirements
or in other cases when the imposition of mass limitations is appropriate.
It shall be unlawful for any person to lay or install plastic sewer
pipes underground on any public property within the limits of Buchanan County
which do not meet the American Water Works Association specifications.
All costs and expenses incidental to the installation and connection
of the building sewer shall be borne by the user. The user shall indemnify
the PSA from any loss or damage that may directly or indirectly be occasioned
by the installation of the building sewer.
A separate and independent building sewer shall be provided for every
building, except where one building stands at the rear of another on an interior
lot and no private sewer is available or can be constructed to the rear building
through an adjoining alley, court, yard or driveway, the front building sewer
may be extended to the rear building and the whole considered as one building
sewer; but the PSA does not and will not assume any obligation or responsibility
for damage caused by or resulting from any such single connection aforementioned.
Whenever possible, the building sewer shall be brought to the building
at an elevation below the basement floor. In all buildings in which any building
drain is too low to permit gravity flow to the public sewer, sanitary sewage
carried by such building drain shall be lifted by an approved means at the
expense of the user and discharged to the building sewer.
All excavations for building sewer installation shall be adequately
guarded with barricades and lights so as to protect the public from hazard.
Streets, sidewalks, parkways and other public property disturbed in the course
of the work shall be restored in a manner satisfactory to the PSA or other
appropriate entity.
All service laterals abandoned due to building demolition or for any
other reason shall be properly sealed by the owner and inspected by a representative
of the PSA prior to backfilling.
