A.
All users of the Town POTW shall comply with all standards
and requirements of the Act and standards and requirements promulgated
pursuant to the Act, including but not limited to 40 CFR Parts 406
to 471.
B.
All users discharging to the Town of Wawayanda's Sewer
District No. 1, which discharges to the City of Middletown's POTW,
must also comply with the standards and requirements of the City of
Middletown's pretreatment program.
A.
No user shall contribute or cause to be contributed,
in any manner or fashion, directly or indirectly, any pollutant or
wastewater which will interfere with the operation or performance
of the POTW. These general prohibitions apply to all such users of
a POTW whether or not the user is subject to national categorical
pretreatment standards or any other national, state, or local pretreatment
standards or requirements.
B.
Without limiting the generality of the foregoing,
a user may not contribute the following substances to the POTW:
(1)
Except as hereinafter provided, no person shall discharge
or cause to be discharged any of the following described waters or
wastes to any public sewer:
(a)
Any liquid or vapor having a temperature higher
than 140º F.
(b)
Any water or waste which may contain more than
100 parts per million, by weight, of fat, oil or grease.
(c)
Any gasoline, benzene, naphtha, fuel oil or
other flammable or explosive liquid, solid or gas.
(d)
Any garbage.
(e)
Any ashes, cinders, sand, mud, straw, shavings,
metal, glass, rags, feathers, tar, plastics, wood, paunch manure or
any other solid or viscous substance capable of causing obstruction
to the flow in sewers or other interference with the proper operation
of the sewage works.
(f)
Any waters or wastes having a pH lower than
5.5 or higher than 9.0 or having any other corrosive property capable
of causing damage or hazard to structures, equipment and personnel
of the sewage works.
(g)
Any waters or wastes containing toxic or poisonous
substances, including oxygen-demanding pollutants, released at a flow
rate and/or pollutant concentration which would cause interference
with any sewage treatment process or constitute a hazard to humans
or animals or create any hazard in the receiving waters of the sewage
treatment plant.
(h)
Any waters or wastes containing suspended solids
of such character and quantity that unusual attention or expense is
required to handle such materials at the sewage treatment plant.
(i)
Any noxious or malodorous gas or substance capable
of creating a public nuisance.
(j)
Any wastewater which will result in a temperature
exceeding 104º F. (40º C.) at the influent to the sewage
treatment plant.
(k)
Any pollutant in excess of values specified
in the categorical pretreatment standards.
(2)
Grease and oil interceptors.
(a)
Grease, oil and sand interceptors shall be provided
when, in the opinion of the Town, they are necessary for the proper
handling of liquid wastes containing grease in excessive amounts or
any flammable wastes, sand and other harmful ingredients. Such interceptors
may be required for private living quarters or dwelling units if commercial
production at such private residences generates excessive amounts
of grease. All interceptors shall be of a type and capacity approved
by the Town and shall be located as to be readily and easily accessible
for cleaning and inspection.
(b)
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 bolted
in place, shall be gastight and watertight.
No person shall discharge, directly or indirectly, into the POTW, wastewater containing any of the following substances in concentrations exceeding those specified below on either a daily or an instantaneous basis, except by permit or as provided for in § 138-79. Concentration limits are applicable to wastewater effluents at the point just prior to discharge into the POTW ("end-of-pipe" concentrations).
A.

of 2 or less, without prior filtration.
| |
|

|
As determined on a composite sample taken from
the user's daily discharge over a typical operational and/or production
day.

As determined on a grab sample taken from the
user's discharge at any time during the daily operational and/or production
period.

(2)
Any odor or color exceeding concentration limits which
may be established by the Town for purposes of meeting the Town's
National Pollutant Discharge Elimination System permit.

B.
The Town shall determine the total allowable influent
load of each substance from significant industrial users. In determining
the total load of each substance that significant industrial users
shall be allowed to discharge, the Town shall consider: 1) the quantities
of each substance that are uncontrollable because they occur naturally
in wastewater; 2) the quantities of each substance that are anthropogenic
but are nonetheless uncontrollable; 3) historical discharge trends;
4) past pollution control efforts of each significant industrial user
as compared to other significant industrial dischargers of the same
substance; 5) potential for growth in the POTW service area; 6) potential
for more restrictive regulatory requirements to be placed on the POTW
discharge or sludge disposal or sludge reuse method; and 7) treatability
of the substance. The Town shall apply a minimum fifteen-percent safety
factor to be protective of the POTW.
C.
To assure that the total loads so calculated, for
each substance, are not violated, the Town shall issue permits to
significant industrial users limiting discharge loads.
A.
Limitations on wastewater strength or mass discharge
contained in this chapter may be supplemented with more stringent
limitations when, in the opinion of the Town:
(1)
The limitations in this chapter are not sufficient
to protect the POTW;
(2)
The limitations in this chapter are not sufficient
to enable the POTW treatment plant to comply with applicable water
quality standards or the effluent limitations specified in the POTW's
SPDES permit;
(3)
The POTW sludge will be rendered unacceptable for
disposal or reuse as the Town desires, as a result of discharge of
wastewaters at the above prescribed concentration limitations;
(4)
Municipal employees or the public will be endangered;
or
(5)
Air pollution and/or groundwater pollution will be
caused.
B.
The limitations on wastewater strength or mass discharge
shall be recalculated not less frequently than once every five years.
The results of these calculations shall be reported to the Town. This
chapter shall then be amended appropriately. Any issued industrial
wastewater discharge permits, which have limitations, based directly
on any limitations, which were changed, shall be revised and amended,
as appropriate.
The System Operator shall have the authority
to copy any record related to wastewater discharges to the POTW.
A.
Except where expressly authorized to do so by an applicable
pretreatment standard, no user shall ever increase the use of process
water or, in any other way, attempt to dilute a discharge as a partial
or complete substitute for adequate treatment to achieve compliance
with a pretreatment standard.
B.
Dilution flow shall be considered to be inflow.
Grease, oil, and sand interceptors shall be provided as they are necessary for the proper handling of wastewater containing excessive amounts of grease, flammable substances, sand, or other harmful substances, except that such interceptors shall not be required for private living quarters or living units except as provided in § 138-77B(2). Grease interceptors shall be installed in all commercial kitchen facilities serving at a minimum of one large fueling per month. All interceptors shall be of a type and capacity approved by the System Operator in consultation with the Town Engineer and shall be so located to be easily accessible for cleaning and inspection. Such interceptors shall be inspected, cleaned, and repaired regularly, as needed, by the owner, at his expense.
A.
Solid waste grinders at or serving commercial establishments,
institutions or industries shall not discharge into the Town POTW
if there is a combined sewer overflow (CSO) on the sewer lines conveying
the waste to the POTW treatment plant. Solid waste grinders for these
purposes shall be permitted only upon consent of the Town.
B.
Solid waste grinders serving residential users shall
be permitted only with consent of a professional engineer and/or approval
of the Town.
The Town Board may reject a user's wastewater, on recommendation of the System Operator, when it is has been determined that the wastewater contains substances or possesses characteristics which have a deleterious effect on the POTW and its processes or on the receiving water or which constitute a public nuisance or hazard. See § 138-101.
