[Ord. No. 190408E, 4-22-2019]
A.
The admission into the POTW of any wastewater containing any quantity
of pollutant shall be subject to review and approval of the Director.
Where necessary, in the opinion of the Director, the owner of the
property or premises producing such wastewater shall provide, at their
expense, such preliminary treatment as may be necessary to reduce
pollution or certain pollutants to within the maximum limits provided
for in this Chapter or to control the quantities or rates of discharge
of such wastewaters.
B.
Users of the POTW shall provide necessary wastewater pretreatment,
as required to comply with these Code Sections, within the time limitations
specified by Federal, State, or City, whichever is more stringent.
Any facilities required to pretreat wastewater to a level acceptable
to the City, shall be provided, operated, and maintained at the user's
expense. Detailed plans showing the pretreatment facilities and operating
procedures shall be submitted to the City for review and shall be
acceptable to the City before construction of the facility. The review
of such plans and operating procedures will in no way relieve the
user from the responsibility of modifying the facility as necessary
to produce an acceptable discharge to the City under the provisions
of this Chapter.
[Ord. No. 190408E, 4-22-2019]
A.
All new buildings within the City of Willard or in any area where
there is an availability of sewers in a jurisdiction with which the
City has an interjurisdictional sewage treatment agreement are required
to connect to a public gravity sewer if the sewer is adjacent to the
property and located in a public right-of-way, utility or sewer easement
immediately abutting the property unless otherwise approved by the
Director of Public Works. All new lot splits, subdivisions or land
divisions within the City must provide a public gravity sewer adjacent
to each proposed lot using the City of Willard design standards, unless
otherwise approved by the Director of Public Works. No new building
can be constructed, nor can lot splits, subdivisions or land divisions
occur unless a public gravity sewer is on-site or adjacent to the
property, unless this requirement is waived by the Director. Factors
that the Director may consider as justification for such a waiver,
may include, but are not limited to:
1.
The new structure is an alteration or addition to an existing,
functioning structure that is currently served by an approved on-site
septic system and will not significantly increase sewer flows.
2.
The land meets the requirements for an on-site wastewater system.
3.
The new structure or land use will not require public sewer
or water.
4.
Connecting to public sewer would be impractical or impossible
for reasons such as:
a.
The adjacent right-of-way or easement contains natural or man-made
obstructions, such as streams, ravines, elevation changes, solid rock,
drainage structures, or other utilities that would be cost prohibitive
to cross.
b.
The adjacent right-of-way is owned by another entity that refuses
to grant permission to cross property boundaries.
B.
If a public sewer is made available by construction of capital improvements
and included in a Board of Aldermen approved sewer district, any existing
building that requires a sanitary sewer connection must connect to
the sewer within ninety (90) days after the sewer is available, provided
that the sewer is on-site or adjacent to the property and is located
within a public right-of-way, utility or sewer easement. If a public
sewer becomes available to any existing building, that building shall
connect the sewer lines, unless they meet certain exceptions. These
exceptions, include, but are not limited to:
C.
No person shall make any connection to the POTW, either direct or
indirect, without written permission from the Director, or reconnect
wastewater services when such services have been disconnected for
non-payment of a bill for wastewater services unless such bill for
wastewater services, including charges for disconnection, has been
paid in full.
D.
No person shall tap into any sanitary sewer line of the POTW except
by using an approved tapping machine and an approved connection fitting
unless otherwise approved by the Director. The Director shall develop
reasonable rules and regulations on tapping and connecting procedures.
These rules and regulations shall take force and effect five (5) days
after the rules and regulations shall be filed in the office of the
City Clerk.
E.
Any person outside the City limits that requests permission to connect
to the POTW must: (1) file an application for a special connection
permit; and (2) comply with (C) and (D) above; and (3) execute and
file with the recorder of deeds an Irrevocable Consent to Annex into
the City limits pertaining to their property.
[Ord. No. 190408E, 4-22-2019]
No person shall discharge any wastewater or pollutant directly
into a manhole or other opening of the POTW, other than through an
approved building sewer, unless he/she shall have been given written
permission to do so by the Director.
[Ord. No. 190408E, 4-22-2019]
A.
The Director may, after informal notice to the discharger, take whatever
steps are reasonably necessary to immediately temporarily suspend
a user's sewer use permit, or impose temporary restrictions on discharges,
or halt and prevent the discharge of pollutants to the POTW which
reasonably appear to present an immediate endangerment to the health
or welfare of persons. If the Director determines that an industrial
user's discharge to the POTW does not present an immediate endangerment
to the health or welfare of persons, but presents or may present an
endangerment to the environment or threatens to interfere with the
operation of the POTW, he/she shall notify the discharger, in writing,
setting forth sufficient facts to describe the violation and allowing
a reasonable period of time, which shall be stated in the notice,
to respond or to abate or correct the violation and if the response
or actions of the discharger do not result in abatement and correction
within such period of time, the Director may take action as reasonably
necessary to halt or prevent the discharge.
B.
Any user notified of a suspension of its discharge shall immediately
stop or eliminate its contribution.
C.
In the event of a user's failure to voluntarily comply with the suspension order, the Director shall take such steps as the Director deems necessary, including immediate severance of the sewer connection, to prevent or minimize damage to the POTW, its receiving stream, or endangerment to any individuals. The Director shall allow the user to recommence its discharge when the user has demonstrated to the satisfaction of the City that the period of endangerment has passed, unless the termination proceedings in Section 710.580 of this Chapter are initiated against the user.
D.
A user that is responsible, in whole or in part, for any discharge presenting imminent endangerment shall submit a detailed written statement, describing the causes of the harmful contribution and the measures taken to prevent any future occurrence, to the Director prior to the date of any show cause or termination hearing under Sections 710.570 and 710.580 of this Chapter.
E.
Nothing in this Section shall be interpreted as requiring a hearing
prior to any emergency suspension under this Section.
[Ord. No. 190408E, 4-22-2019]
A.
Holding tank waste may be introduced into the POTW only at locations designated by the Director, and at such times as are established by the Director. Such waste shall not violate Article III of this Chapter or any other requirements established by the City. The Director may require holding tank waste haulers to obtain wastewater discharge permits.
B.
The Director shall require haulers of industrial waste to obtain
wastewater discharge permits, provide proof of vehicle or company
liability insurance, and obtain a City business license. The Director
may require generators of hauled industrial waste to obtain wastewater
discharge permits. The Director also may prohibit the disposal of
hauled industrial waste. The discharge of hauled industrial waste
is subject to all other requirements of this Chapter.
C.
Industrial waste haulers may discharge loads only at locations designated
by the Director. No load may be discharged without prior consent of
the Director. The Director may collect samples of each hauled load
to ensure compliance with applicable standards. The Director may require
the industrial waste hauler to provide a waste analysis of any load
prior to discharge.
D.
Industrial waste haulers must provide a waste-tracking form for every
load. This form shall include, at a minimum, the name and address
of the industrial waste hauler, permit number, truck identification,
names and addresses of sources of waste and volume and characteristics
of waste. The form shall identify the type of industry, known or suspected
waste constituents and whether any wastes are RCRA hazardous wastes.
E.
All wastewater transported to the POTW for treatment shall be transported
in a vacuum truck or tanker in compliance with all Federal motor carrier
licensing and safety regulations — Title 49, Code of Federal
Regulations, Parts 390 through 397. Vehicles shall be operated by
a person holding a valid commercial driver's license with applicable
endorsements under State and Federal motor carrier law for the vehicle
operated and all contents being transported. Containers such as drums,
totes, portable container, other non-permanently mounted containers,
or vehicles without value Missouri State Highway Patrol Commercial
Vehicle Enforcement Division approval are prohibited to access the
POTW.
[Ord. No. 190408E, 4-22-2019]
The Director is hereby authorized to determine the cost to receive,
test and administer wastewater which is trucked or hauled to the POTW.
The Director shall file such cost determinations with the City Clerk,
with notice to the Board of Aldermen, and the City thereafter shall
charge for such services in accordance with the amount so filed, unless
countermanded by a resolution of the Board of Aldermen.
[Ord. No. 190408E, 4-22-2019]
The Director shall dispose of all treated sludges and other
by-products of the POTW. He/She may sell such sludges and other by-products
to such persons as may desire to purchase the sludges and by-products
and shall determine a schedule of charges and provide for the collection
of such charges. He/She shall account monthly to the Director of finance
for such sales.
[Ord. No. 190408E, 4-22-2019]
Grease, oil and sand interceptors shall be provided at the user's
expense when the Director determines that they are necessary for the
proper handling of wastewater containing grease or any flammable wastes,
sand and other harmful ingredients, except that such interceptors
shall not be required for private living quarters or dwelling units.
All interceptors shall be of a type and capacity approved by the Director,
shall be compliant with the current adopted Plumbing Code, and shall
be so located as to be readily accessible for cleaning and inspection.
Grease and oil interceptors shall be constructed of impervious materials
capable of withstanding abrupt and extreme changes in temperature.
They shall be of substantial construction, watertight, and equipped
with easily removable covers which when butted in place shall be gastight
and watertight. All devices must be installed to meet manufacturer
installation requirements for proper operation. When installed, all
grease, oil and sand interceptors shall be maintained by the user,
at his/her expense, in continuously efficient operation.
[Ord. No. 190408E, 4-22-2019]
A.
Grease traps shall be provided on kitchen drain lines from institutions,
hotels, restaurants, school lunch rooms, nursing homes and facilities
and other establishments from which significant amounts of grease
may be discharged to the treatment facility.
B.
Grease traps should be located as close to the fixtures being served
as possible and should receive only the waste streams from grease-producing
fixtures. Sanitary waste streams, garbage grinder waste streams and
other waste streams, which do not include grease, should be excluded
from passing through the grease traps. This separation is mandatory
for new construction or replacement facilities. Grease traps must
be cleaned on a regular basis and must be readily accessible for this
purpose.
C.
Sizing of grease traps is based on wastewater flow and can be calculated
from the number and kind of sinks and fixtures discharge to the trap.

grease layer. Cleaning should take place in accordance with the trap
manufacturer's instructions, when the bottom of the floating grease
layer approaches within six (6) inches of the trap outlet elevation
or when the sludge layer approaches within twelve (12) inches of the
trap outlet elevation, whichever comes first.
G.
The owner of any establishment required to comply with this Chapter
shall maintain a log showing dates of FOG or grease removal, the amount
of grease removed and the name of the individual and company that
removed the grease. The log shall be signed by the owner or operator
of the business and the person who does the hauling. The log shall
be available for review by the inspector at each site visit.

Standards or for any categorical user when the local limits for said
user are more restrictive than the Federal Categorical Pretreatment
Standards.
B.
New source and new users are required to comply with applicable pretreatment
standards within the shortest feasible time, not to exceed ninety
(90) days from the beginning of discharge. New source and new users
shall install, have in operating condition, and shall start up all
pollution control equipment required to meet applicable pretreatment
standards before beginning to discharge.
C.
Any wastewater discharge permit issued to a categorical user shall
not contain a compliance date beyond any deadline date established
in EPA's Categorical Pretreatment Standards. Any other existing user
or categorical user that must comply with a more stringent local limit
which is in non-compliance with any local limits, shall be provided
with a compliance schedule placed in an industrial wastewater permit
to insure compliance within the shortest time feasible.
