OPIUION
 AND
 ORDER
 OF
 THE
 BOARD
 (by I.
 Goodman):
On March
 8,
 1978 Complainant filed this action against
Davenport Packing Company,
 Inc.
 (Davenport) alleging violations
of Rules
 953(a) and 701(a)
 of Chapter
 3:
 Water Pollution Rules
and Regulations, and consequential violations of Sections 12(a)
and
 (b)
 of the Illinois Environmental Protection Act
 (Act).
 On
March 15,
 1979 the Board granted Davenport’s motion to add the
Village of Milan,
 in Rock Island County,
 as party Respondent.
Although discovery was initiated in early April of 1978, and
hearing was first set for May
 25,
 1978,
 no hearings were held
until September 9—11,
 1980,
 almost two and one—half years
 later.
The Board’s docket contains thirteen motions
 to continue hearing.
The post—hearing motion to
 dismiss
 Milan as party Respondent is
granted since no complaint alleging violations by Milan exists
in the record.
 The Board has received no public comment in this
‘natter.
Davenport is
 located within the Village of Milan,
 Illinois
tnd discharges its wastewater
 into Milan’s sewer system.
 Daven—
jx)rt’s facility processes cattle, beginning with live animals and
ending with dressed carcasses which are further processed
 by
others.
 The process includes slaughtering, bleeding, skinning,
an~1dismemberment.
 During this process, blood and solids,
excluding internal organs, are washed into a collection basin
along with other wastewater.
 The collection basin acts as a
settling and skimming tank,
 the discharge from which is directed
to the Milan
 sewer system.
 Each morning the basin is pumped down
and discharged into a rotating strainer.
 The strainer retains
44—1
2
solids and congealed grease,
 if any,
 for
 recovery
 as
 byproduct
by Davenport; the remainder
 is discharged to the Milan sewers.
The Agency alleges that wastewater was discharged by
Davenport into the Milan sewer system at a flow of over 50,000
gallons per average workday since December 31,
 1972.
 This waste—
water
 is alleged to contain toxic and other pollutants and to
contribute over
 15
 of both hydraulic flow loading and biological
loading of the Milan sanitary treatment plant.
 During a period
from October,
 1976 through June,
 1977, Milan’s sanitary treatment
plant effluent allegedly exceeded the concentrations of biochemical
oxygen demand
 (BOD) and total suspended solids
 (TSS) allowed by
the State.
 The Agency alleges that these excursions were caused
by Davenport’s alleged violation of Rule 701(a) of Chapter
 3, e.g.,
that Davenport’s wastes discharged to sewers owned by the Village
of Milan are prohibited because, by reason of their nature or
quality, they may cause the plant’s effluent to violate applicable
effluent standards.
 In addition, the Agency alleges that Davenport
is a major contributing industry pursuant to Rule
 104 of Chapter
3 of the Board’s Regulations,
 and as
 such, operated pretreatment
equipment without having first been issued an operating permit by
the Agency.
The first issue to be considered by the Board is the
allegation that Milan’s excursions were caused by the type and
manner of discharge by Davenport to the sewer.
 There is some
question as to precisely what standards Milan was to meet during
the period of the complaint.
 Board Rule 404(f) calls for a
limitation of
 4 mg/i BOD and
 5 mg/i TSS,
 The Board recently
repealed Rule 404(f) with respect to the 4/5 standard,
 leaving in
its place Rule 404(c) which calls
 for a 10/12 standard.
 Milan’s
NPDES permit contains limitations of
 10 mg/l BOD and 15 mg/i TSS
arid
 the
 4/5
 limits under certain conditions.
 ifl
 addition,
 one
 of
the permits was modified by an Enforcement Schedule Compliance
Letter issued by the United States Environmental Protection Agency
setting limitations of 50 mg/i BOD and 50/mg/l TSS.
 Fortunately,
the Board need not make a determination as to which standard
applied
 in this case since there is ample evidence that Milan
exceeded even the most generous of the limitations cited
 (R.368;
Complainant’s Group Exhibit 16).
Milan’s treatment plant was designed for a hydraulic
discharge of 412,500 gallons per day from Davenport out of a total
loading of 1.7 million gallons per day for the entire treatment
plant
 (R.626).
 Complainant’s Exhibit 7 contains certain results
of a study made by a consultant for Milan concerning the hydraulic
and organic loading of Milan’s sanitary treatment plant by the City
and by Davenport.
 Although part of the data falls outside of the
 time period encompassed by this Complaint,
 the data ascertained
during the first eight work days of the study is competent.
 That
data indicates an average workday hydraulic flow of approximately
255,000 gallons or about
 18.8
 of the total
 flow (Complainant’s
Exhibit 7).
 Considering those figures and the fact that the
4A— 2
3
basement of Davenport’s plant began flooding within an hour after
Davenport’s sewer had been blocked leads the Board to find that
Davenport
 discharged
 in
 excess
 of
 50,000
 gallons
 per
 day
 to
 Milan’s
sewers,
 contributing
 in
 excess
 of
 15
 of
 Milan’s
 total
 hydraulic
load
 (R.
 391—4;
 Complainant’s
 Exhibit
 7).
The Plant Superintendent of Milan’s sewage treatment plant
testified that Davenport is the only major industry which
discharges
 to
 the
 Village
 sewer
 system
 (R,35l,
 366).
 According
to the record, Davenport routinely pumps the waste from its cal—
lection basin through a rotary screen and into the sewer system
during a three—to—four hour period each workday mornings.
 The
purpose of this process
 is
 to recover solids from the collection
basin
 for
 further
 processing.
 A
 sudden
 sustained
 increase
 in
loading
 on the sewage treatment plant may well load the treatment
plant past its hour-by—hour capacity.
 Therefore, since material
from Davenport
 is discharged to the treatment plant as described
above,
 the
 treatment
 plant
 might
 experience
 higher
 total
 levels
of
 discharge.
 The
 competent
 portion
 of
 Complainant’s
 Exhibit
 7
shows
 an
 average
 percent
 flow
 discharge
 from
 Davenport
 Packing
Company
 of
 18.8
 of
 the
 total
 flow
 to
 Milan,
 an
 average
 of
 59,1
of
 the
 total
 BOD
 loading,
 and
 an
 average
 43,3
 of
 the
 TSS
 loading,
all
 based
 on
 data
 collected
 on
 workdays
 only.
 The
 foregoing
averages compare favorably with those averages indicated for
the entire twenty-eight day period,
 some of which was collected
subsequent to the filing of the Complaint herein.
 Testimony
concerning
 the
 “reddish
 brown
 coloration”
 of
 the
 raw
 sewage
entering Milan’s treatment plant is further indication of the
effect of Davenport’s discharge upon the treatment plant
 (R,73—75).
Davenport has made no effort to present witnesses in rebuttal
or in mitigation of the evidence presented to support the Complaint
but rather attempted to show by cross—examination and argument that
Complainant had failed to present a prima facie case,
 In addition,
Davenport argues that the problem lies with Milan and its treatment
plant.
 The Board disagrees.
 Davenport cannot discharge its
effluent to the sewer system of the City of Milan in any manner it
desires and then claim that the problem is with Milan’s inability
to cope with the discharge.
 This is precisely the situation that
the Board addressed when it promulgated Rule 701 which prohibits
the discharge of wastes to any sewer owned by any municipality
which, by reason of its nature or quantity, may cause the effluent
from the treatment works to violate applicable effluent standards.
The Board finds Davenport in violation of Rule 701(a) and
 12(a)
 of
the Act.
 Therefore, based on the design criteria and discharge
amounts supporting the violation of Rule 701(a)
 and 12(a)
 of the
 Act,
 the Board further finds that Davenport is a major contributiciq
industry as defined by Rule
 104 of Chapter
 3:
 Water Pollution.
The other issues the Board must consider in this case
 is
whether or not the collection basin and the rotary screen operated
by Davenport from which it discharges its effluent to the Milan
sewer system constitutes a pretreatment system and if
 so,
 does
 it
44—3
4
require
 an
 operating
 permit.
 A
 pretreatment
 works
 is
 a
 treatment
works
 designed
 and
 intended
 for
 treatment
 of
 wastewater
 from
 a
major contributing industry,
 The Board has previously found that
Davenport is a major contributing industry.
 Davenport argues that
the only purpose for the collection basin is to collect the
 large,
heavy material for the purpose of recovery.
 In support of their
argument, Davenport indicates that the collection basin is pumped
down
 through
 the
 rotating
 screen
 once
 each
 morning,
 and
 the
material
 collected
 in
 the
 rotating
 screen
 is
 recovered
 and
reprocessed.
 Davenport
 also
 appears
 to
 argue
 that
 there
 is
 no
discharge from the collection basin directly to the sewer,
 The
Agency
 agrees
 that
 the
 collection
 basin
 and
 rotating
 screen
situated just prior to discharge to Milan’s sewer system was
intended
 to
 and
 does
 allow
 settling
 of
 large
 and
 heavy
 masses
which result from the slaughter operation.
 However, the Agency
claims
 that
 without
 this
 collection
 basin,
 this
 material
 would
be and has been discharged directly into Milan’s sewage system,
could overload the BOD
 and
 TSS amounts at the Milan treatment
plant, could block the Milan sewage system, and could cause
Davenport’s basement to flood.
The
 Board
 must
 reject
 Davenport’s
 argument.
 Since
 Davenport
presented no witnesses, there is only the Agency’s evidence of
such a discharge:
 the hydraulic load discharged to Milan’s sewer
system;
 the photographs of the obviously unscreened material
contained in Davenport’s effluent and the fact that Davenport’s
 basement began flooding within an hour after its sewer was blocked.
This indicates to the Board that there was indeed unscreened
effluent discharging from Davenport’s collection basin notwith-
standing the fact that the Agency did not present a witness who
had
 actually
 seen
 the
 discharge
 (Complainant’s
 Exhibits
 17,
 18
and
 19;
 R.388—394),
 The
 Board
 finds
 that
 Davenport’s settling
tank
 is
 a
 pretreatment
 works,
 The
 fact
 that
 Davenport
 recovers
the
 solids
 trapped
 in
 the
 tank
 and
 reprocesses
 them
 is
 of
 no
consequence.
 The solids would have to be recovered and disposed
of
 in some manner,
 such as a landfill,
 in any event,
Having determined that Davenport operates a pretreatment
system, the Board must address the possibility of an exemption
from the operating permit requirement.
 Board Rule 953(d)
expressly excludes from the requirement of an operating permit
any pretreatment works that will not discharge:
 toxic pollutants:
15
 or more of the total hydraulic flow received by the treatment
works; or
 15
 or more of the total biological
 loading received by
 the treatment works as measured by BOD.
 Davenport argues that all
three of these conditions must be met before an operating permit
is required.
 Thus,
 it states,
 in the absence of
 a showing that
Davenport has discharged toxic pollutants,
 there was no operating
permit requirement.
 The obvious corollary to that argument
 is
that unless
 a pretreatment plant discharges more than 15
 of the
total BOD loading and total hydraulic flow received by the treat-
ment works,
 it need not have a pretreatment permit regardless of
the amount or type of toxic pollutants it discharges.
 Davenport’s
44—4
5
interpretation
 of
 Rule
 953(d)
 is
 patently
 absurd.
 The
 Board
holds that a pretreatment works requires an operating permi.t if
any
 one
 of
 the
 three
 conditions
 stated
 exists.
 The
 Board
 has
previously found that Davenport discharges more than
 15
 of
 both
the hydraulic flow and the biological
 loading received by Milan’s
treatment works
 and, therefore,
 an operating permit for the
pretreatment works is required.
 The Board finds Davenport in
violation of Rule 953(a) of the Board’s Water Regulations
 and
12(b) of the Act.
It is apparent that Davenport must modify
 its procedures
and/or its equipment to alleviate its
 loading on the Milan
sewage treatment plant so that the treatment plant might achieve
compliance with the Board’s regulations.
 To that end,
 the Board
will order Davenport to develop a plan for pretreatment of its
discharge to be presented to the Agency within
 90 days of the
date of this Order.
 Davenport shall also obtain the permits
required by its pretreatment works from the Agency.
In considering a penalty, the Board must consider the factors
listed under Section 33(c)
 of the Environmental Protection Act.
There appears to be no issue with regard to the social and
economic value of Davenport or the suitability or unsuitability
of the pollution source to the area in which it is located or the
technical practicability or economic reasonableness of reducing
or eliminating the discharge.
 With regard to the character and
degree of injury to or interference with the protection of the
health, general welfare, and physical property of the people,
the Board finds that Davenport’s discharges have interfered with
Milan’s ability to control the effluent from its sanitary
treatment plant.
 In addition,
 the record indicates that Davenport
has been reticent in addressing the problem (Complainant’s Exhibit
1, Respondent’s Exhibit
 1).
 The Board shall therefore assess a
 penalty
 of
 $2,000
 against Davenport in order to
 further
 the
purposes
 of
 the
 Illinois Environmental Protection Act.
This Opinion constitutes the Board’s finding of facts and
conclusions in this matter.
