OPINION AND
ORDER
OF THE BOARD
 (by J.D. Dumelle):
This matter comes before the Board upon a July 15,
 1981
complaint filed by the Illinois Environmental Protection Agency
(Agency)
 alleging that the Victory Memorial Hospital Association
(Hospital)
 operated its general hospital
 facility in such a manner
as to violate Rules 102,
 202 and 203 of Chapter
 8:
 Noise Pollution.
Hearings were held on May 4,
 5,
 6,
 18 and 20,
 1982 at which the
parties and some members of the public appeared and testified.
Briefs were filed in lieu of closing arguments.
The Hospital is a not—for—profit corporation
 (R.
 953—954)
which operates a full-service hospital located at 1324 North
Sheridan Road in Waukegan.
 Along the Hospital’s northern proper-
ty line is a powerhouse which
 is separated from the main building
 and houses the electrical, cooling,
 heating, water,
 fire protec-
tion and medical gas equipment for the main building
 (R. 907).
Associated with this powerhouse are two air—cooling towers re-
ferred to as the east and west towers
 (R.12).
 The east tower is
located on the roof of the powerhouse and has been in operation
since 1966.
 It is about 40 feet from the Hospital’s northern
property line (R.13 and 906).
 The west tower is
 located 12—13
feet from the northern property line slightly west of the power-
house and was installed in 1978
 (R.13 and 14).
Stanley Avenue is an east—west street located approximately
200 feet north of the Hospital’s property line
 (R.249,
 460 and
602—603).
 Along Stanley Avenue and directly north of the Hospital
property is a residential area where most of the citizens
who are affected by the noise and who testified at hearing reside
(R.21).
51-99
—2—
The Agency alleges that the Hospital has emitted noise from
its property which exceeds permissible daytime
 (Rule 202) and
nighttime
 (Rule
 203) noise limitations and which unreasonably
interferes with the enjoyment of life and property of those
residents along Stanley Avenue whose property is adjacent to the
Hospital
 (Rule 102).
 The cause of the noise is alleged to be the
 powerhouse and the two associated air-cooling towers.
The Hospital contends that none of the numerical violations
has been proven because the Agency has based its allegations on
improper standards
 (due to improper land use classification),
has incorrectly measured ambient values, has used other improper
measurement techniques and outdated noise results.
 Further,
the Hospital contends that a violation of Rule 202 or 203 must
be shown as a prerequisite for enforcement under Rule 102 and
that even if that is not true consideration of Section 33(c)
factors are mandated which would preclude a finding of violation.
The Board
 first considers the Hospital’s contention that
the proper classification for the Hospital
 under the Standard
Land Use Coding System is Class C under Code 4890
 (“Other
Utilities”)
 so far as it relates to the noise violations alleged
jfl this action rather than Class A under Code 6513
 (“Medical
and other health services”).
 The Board rejects this contention.
While not precluding the possibility of contiguous property
under common ownership falling under separate classifications,
such is clearly not the case here.
 The function of the powerhouse
and the associated cooling towers
 is inextricably tied to the
predominant use of the land (providing medical services) and is
used for no other purpose;
 the powerhouse and towers are physically
connected to the hospital by underground tunneling;
 and the alter-
native use suggested
 (as a utility)
 is stretched too far where,
as here, the services provided are used at a single facility.
Finally, the logical extension the Hospital’s reasoning is that
any Class
 A land is magically transformed into Class C land
whenever an air conditioner is placed in a window on Class A
property.
Since the Board concludes that the A to
 A limitations of
Rules 202 and 203 are applicable to the Hospital, the Board must
next consider whether proper measurement techniques were used
 in
establishing violations of those standards.
The Hospital’s major attack is on the Agency’s determination
of the ambient noise conditions.
 The Hospital argues that improper
methodology was used and that most ambient measurements were taken
at sites far removed from source measurement sites and in areas
which did not accurately reflect ambient conditions.
The Agency uses GenRad Model 1933 noise meters which
have a rapid response fluctuating needle and no paper readout
(R.299,
 303 and 745—756).
 The operator disregards peaks and
notes the reading when the needle is steady,
 thus deliberately
51-100
disregarding extraneous readings (R,142—146 and 303—304).
 The
Hospital contends
that
it is appropriate to include many of the
noise sources which
the
Agency disregards through this technique,
and has attempted
to
establish as much through the testimony of
Mr. Lyle Yerges,
 the
Hospital’s noise consultant
 (R.657—659).
He testified
that sounds
from traffic,
 a “power plant on the
lakefront, plane over flights,
 insects,
 occasional bursts of
wind and birds~should
be
included in the ambient, but that an
“over flight
or any
sharp unusual level would have been excluded
if it had occurred’~when he was taking a measurement
 (R.658),
However,
 the Hospital
fails to establish that this is not
in fact what
Kevin Moore,
the person who conducted most of the
relevant surveys~d±d~.
While
Mr.
 Moore admitted that a bird
flying overhead making noise may or may not be included, that
he would not
take readings
near an operating air conditioner and
that an audible
airplane
oyerflight would he disregarded as
might an isolated
car passing
by,
 he includes such noises when
they are
 “a
steady part. of the
ambient”
 (R.143—146).
It
 is
difficult to
determine how the Agency’s technique
differs from
that of
 Mr.
Yerges.
 While it may be true that Mr.
Moore
 disregarded
 somewhat
 more
 of
 the
 background
 sounds
 than
Mr.
 Yerges
 would have,
 that
is
 not
 the
 critical
 factr.
 As
Mr.
 Moore
 explained,
 while
the
 inclusion
 of
 more
 background
 sounds
would
 result
 in a
higher
 ambient
 reading,
 such
 a
 reacting
 would
not
 affect
 the number
of
apparent
 violations
 (R.
 149).
 The
reason is that
the ambient
 measurement
 is
 used
 for
 comparative
purposes.
 Thus,~
the critical
 factor
 is that the same noises
be disregarded
when taking the
 source
 measurements
 as
 are
 di~—
regarded when
 laking the
 ambient
 measurements.
 The record
gives no indication
mat
noises were included when source measure-
ments
 were
 taken
 (other ti~anthose
emanating
 from
 the
 source)
which
 were
 not
rociaded in
determining
 the
 ambient.
The Hospical
alec
argues that the ambient measurements
 should
have been taken
at the same
sites as the source measurements because
measurements can
be affected
by topography and location.
 Clearly,
measurements
taken at the
same sites would be preferable,
 as
Mr.
 Moore admitted
 (R.
 141).
 However, he further pointed out
that this is
not true when
the source cannot be turned off
(R.
 141),
 and
that
because the Hospital
 is “a big place and they
were pretty busy~he decided not to contact the Hospital
 to turn
off the source
 in this
case,
 (R.
 142—143).
 Rather, except for
two cases,
 ambient readings were taken at other locations.
To establish
that this
resulted in improper noise survey
results,
 the Hospital points out that most of the ambient measure-
ments were taken in
the
front yard of the De Rose residence such
that the home
was between
the measurement site and the Hospital
(Agency sites
 4
and
 5,
 Ex.
 C-22).
 The Hospital contends that such
sites
 fail to
take into account
the “funneling effect” of the
ravine which
runs west
from Sheridan Road between the northern
boundary of the
Hosp:Ltal~s
property and the residences along
51-101
—4—
Stanley Avenue and that they, therefore,
 fail to properly reflect
contributing effects of traffic volume and noise.
The support for these propositions is mostly theoretical.
Major Hearn,
 Jr., Director of Agency field operations, did testify
that the ravine could act as a “funnel of sound...up toward Mrs.
De Rose’s lawn”
 (R. 887), but gave no indication of how much an
effect it might have.
 In
 fact, the only witness to even speculate
on the magnitude of the effect was the Hospital’s own witness,
Mr. Yerges, who testified that the ravine would have “no attrib-
utable effect”
 (H.
 738 as corrected by the Agency).
 Further,
Mr.
 Hearn testified that he had no reason to believe that ambient
measurements
taken
 ic1 the De Rose’s front yard would differ
significantly from those taken in the backyard
 (R.
 871).
In its closing brief the Hospital attempts to show that
the ambient levels used for most of the noise surveys are lower
than the ambient levels measured at the same site as the source
readings
 (Resp.
 Brief,
 p.
 46).
 It presents a table showing the
ambient levels used for all daytime noise surveys where the
ambient was measured at
 a site other than the site where the
source was measured and compares them to the ambient measure-
ments taken on June
 12, 1979 where ambient and source measure-
ments were taken at the same site.
 The table shows that in the
500 to 8000 Hertz octave bands 26 of
 30 ambient measurements
taken at alternate sites were lower than the June 12,
 1979
ambient levels.
 If the June
 12 ambient measurements were used
for purposes
of
correction the source levels when corrected
for the ambient would be lower.
 Further, the table
 shows that
18 of the
 19
apparent
violations were in those octave bands.
Thus, given
that
Mr.
 ilearn testified that vehicle traffic noise
is mostly in these same bands, the Hospital concludes that the
ambient measurements taken at alternate sites did not accurately
reflect traffic noise which would have affected source measure-
ments.
However, the Hospital fails to note that a second survey
taken on April
 25,
1980 also measured the ambient levels at the
same site where the source measurements were taken.
 If those
ambient levels were used for comparison with the other surveys
each ambient measurement in the 500 to 8000 Hertz octave bands
taken at alternate sites would be higher
 (or equal to)
 the April
 25,
1980 levels, thereby increasing the source levels when corrected
for ambient,
 Thus,
 all apparent violations would appear at least
as large as those presented by the Agency.
Furthermore,
 if the ambient measurements of June 12,
 1979
and April
 25,
 1980 are averaged and compared with the average
ambient values at alternate sites for the 500,
 1000,
 2000 and
4000 Hertz octave bands (which include all but one of the apparent
violations),
 the largest discrepancy is about
 1 dB. Alternate site
measurements are 1,17 dB lower at 500 Hz.,
 0.67 dB higher at
1000 Hz and 0,5 dB higher at 2000 and 4000 Hz.
51-102
—5—
Based on the data and the testimony presented at hearing,
the Board finds that the use of alternate sites for measure-
ment of the ambient was appropriate in this case although greater
effort to secure assistance from the Hospital to allow ambient
measurements to be taken at the same sites as the source measure-
ments would have been appropriate.
 It is preferable to do so
to avoid arguments such as those presented by the Hospital.
The Hospital also argues that reflective surfaces and nearby
small objects were not taken into consideration when source
measurements were taken and that since ambient measurements were
generally taken at other sites,
 doubt is cast upon the source
measurements.
 The Hospital points out that sound measurements
should not be taken within 25 feet of reflective surfaces nor
within
 5 feet of small objects
 (Resp.
 Ex.
 2).
 However, the
Hospital
 fails to present any evidence that measurements were
taken in violation of these guidelines.
Measurements taken near reflective surfaces should be correct-
ed downward
 (R.
 131-140) and
 Mr.
 Moore
 did
 testify
 that there were
some such objects
 in the area of Site No.
 6.
 However, he also
testified that he “didn’t feel they would have any effect on the
measurements”
 (H.
 130).
 While Mr.
 Yerges testified in general
that there were objects
 in the area could affect the source
measurements,
 he did not attempt to quantify the effect
 (R.
 713,
714 and 739).
 Given that nothing more than mere speculation was
offered in this regard,
 the Board
 finds that neither reflective
surfaces nor small objects in the area of source measurement have
 been shown to affect the Agency’s data.
The next attack on the Agency’s data is that noise testing
procedures have not been revised “to reflect current engineering
judgement and advances in noise measurement techniques” as required
by Rule 103.
 The Hospital contends that graphic recorders,
 as
used by Mr.
 Yerges, are more consistent with current engineering
judgment
 (H. 627~628and 636-637) and that A—Weighted readings
are preferred to octave band analysis
 (R.
 628).
 However, as
the Agency points out, both methodologies were in existence and
considered when the noise rules were promulgated, and Mr. Yerges
acutally presented testimony against the proposed rules
 at that
time
 CR.
 719—720),
 Thus, the Board has fully considered this
methodological question before and finds that nothing
 in this
record warrants a reversal of its previous determination.
The Hospital’s final attack on the Agency data
 is that most
of the noise surveys were made prior to the Hospital’s modifi—
cations to reduce noise
 levels, the last of which was completed
prior to the 1981 cooling season.
 However, after the fact attempts
at compliance do not constitute a defense
 to an enforcement action
although they may be considered in mitigation of any penalty
assessed.
 Therefore,
 the Board finds that the Agency’s noise
survey results are supported by the weight of the evidence.

Despite
 this
 data
 the
 Hospital
 contends
 that
 Rule
 203
violations
 cannot
 be
 found
 against
 it
 in
 that
 the
 July
 10,
 1980
Notice
 of
 Enforcement
 made
 no
 reference
 to
 nighttime
 violations
and
 because
 Site
 No,
 6
 was
 an
 improper
 site
 for
 nighttime measure-
ments.
At
 the
 time
 the
 Notice
 of Enforcement was served, there
was
 no
 requirement
 that
 such
 notice
 be
 given
 prior
 to
 the
 filing
of
 the
 complaint.
 Since
 the
 complaint
 in
 this
 matter
 fully
informed
 the
 Hospital
 of
 allegations
 of
 violations
 of
 nighttime
standards,
 this
 argument
 is
 without
 merit.
The
 argument
 that
 Site
 No,
 6
 was
 improperly
 used
 to
 establish
a
 nighttime
 violation
 is
 also
 without
 merit.
 A
 person
 has
 a
 right
to
 the
 enjoyment
 of
 the
 full
 extent
 of
 his
 property
 at
 anytime
of
 day.
 Further,
 the testimony showed that Site No.
 6
 is a
 lawn
area used by the Machnichs,
 that the grass was mown,
 that a
pathway led to the location and that a barbecue grill was nearby
CR.
 127—128).
 This testimony established that the area could
be used during nighttime hours, but even
 if that were not the case,
Rule 203 applies to property line emissions, not to the enjoyment of
property which is more properly considered with respect to Rule
102 violations and penalties.
Therefore,
 the Board finds that the Hospital violated Rules
202 and 203 at the times and places indicated in the table above.
The Board next considers whether a violation of Rule 102
has been proven.
 The Hospital contends that Section 24 of the
Environmental Protection Act
 (Act) and Rule 102 merely require
compliance with Board’s emission standards and that Rules 202
and 203 simply define what constitutes a reasonably sound
emission level.
 The Hospital than concludes that absent a finding
of violation under Rules 202 or 203,
 no violation of Rule 102
may be found.
Since the Board has found violations of Rules
 202 and 203,
this argument loses its vitality.
 However, the Board notes
that “Section 24 and Rule 102, when read in conjunction with Section
33(c), contain sufficient standards to afford.. .due process of
law.”

 IPCB,
 37 Ill,App.3d 264,
364 N.E.2d 212 (1976).
 Thus,
 a Rule 102 violation can be found
regardless of compliance or non—compliance with numerical stan-
dards.

The Hospital
 is correct,
 however, that the Board must consider
the Section 33(c)
 criteria before a violation of Rule 102 can
be found.
 The Hospital contends that an analysis of those

 is in conflict with Ferndale
Heights

 358 N.E.2d 1228
 (1976), that case is overruled.

criteria establish that the record supports the reasonableness of
its position.
 The Board disagrees.
Several
 citizens
 from
 the
 residential
 area
 north
 of
 the
 Hos-
pital
 testfied
 concerning
 the
 ‘character
 and
 degree
 of
 injury
to,
 or
 interference
 with
 the
 protection
 of
 the
 health,
 general
welfare
 and
 physical
 property
 of
 the
 people’ Section
 33(c)(1).
Mrs.
 De
 Rose
 lives
 directly
 north
 of
 the
 Hospital
 and
 is
 affected
by
 noise
 from
 both
 the
 east
 and
 west
 towers
 (R.
 182
 and
 Comp.
 Thc
 22).
She
 testified
 that
 she
 can
 hear
 a
 noise
 that
 ‘sounds
 like
 you
are
 passing
 an
 open
 factory
 door’
 from
 her
 second
 floor
 bedrooms,
the
 back
 porch,
 the
 kitchen
 and
 her
 entire
 backyard
 (R.
 189).
The
 noise
 has
 made
 her
 irritable
 and
 nervous,
 has
 affected
 her
sleep and has
made
it difficult to watch television (R. 190).
She also testified that she can no longer sit and read on her
back
 porch
 or
 in
 her
 backyard,
 nor
 does
 she
any longer do art
work
 on
 the
 patio
 or
 have
 picnics in the backyard as she used to
(H.
 191).
Mr.
Machnich
lives
 directly
 north
 of
 the
 west
 tower
 and
 can
hear a fairly constant rumbling noise from the east tower, and
from the west tower he hears noises which sound like ‘gushing water’
or ‘air going through water’ as well as a ‘loud pop
and
a whining
noise
that
occurs
every time that it kicks from one speed to
another
 speed’
 (H.
 212,
 218
 and
 Compl.
 Ex.
 22).
 He
 can
 hear
 these
noises
 frdm
 all
 parts
 of
his
 property
 and
 the
 noise
 has
 caused
him
 to
 lose
 the
 natural
 cooling
 effect
 of
 the
 design
 of
 his
house
 along
 the
 ravine
 because
 he
 has
 been
 unable
 to
 keep
 his
windows
 open
 (R.
 219).
 He
 has
 found
that
 the
 noises
 also
 inter-
fere
 with
 his
 sleep,
 conversation
 and
 television
 watching
 and
cause
 him
 to
 be
 unable
 to
 entertain
 colleagues
 and clients
 on
his
 property
 (R.
 219—223).
Mr.
 Stiles,
 who
 also
 lives
 north
 of
 the
 Hospital,
 but
between
the
 two
towers,
 complained
 of
 a
 ‘continuous
 dull
 roar’
 and
 the
‘more
 annoying
 noise’
 associated
 with
 the
 cycling
 of
 the
 west
tower
 (237—238 and
Compl. Ex.
 22).
 The noise has
awakened
him
from
 sleep
 on
 a
 number
 of
 occasions,
 makes
 him
 irritable
 and
 has
deprived
 the
 Stiles
 of
 full
 use
 and
 enjoyment
 of
 their
 backyard.
(R.
 240).
The
 Cullens
 and
 the
 Bartels
 experienced
 similar
 problems
from
 noises
 described
 as
 ‘a
 continuous
 roar’
 along
 with
 ‘winding
up
 noise’
 that
 ‘starts
 like
 a
 skyrocket’
 and a
 noise
 ‘like
 a
rushing sound, running water, a droning sound’
 (H. 462—463
and
599).
 Their
 sleep
 has
also
 been
 disturbed
 and
 the
 backyards
 are
used
 less
 because of the
 noise
 (R. 463 or 598—599).
All the nearby
 residents agree that the noise emitted from
the hospital is irritating to them and interferes with their
enjoyment
of life and property, especially the cycling noises
which occur when
the
 tower
 fans
 shift
 between
 high
 and
low
speeds.
No
 rebuttal
 testimony
 was
presented.
 On
 the
 basis

 Mr~
Hearn,
 however,
testified that tie west tower would not have to be moved that far,
that
 if
 it were moved to the south side of the powerhouse
 (such
that
 the
 powerhouse would act as
 a
 ba~rier) and if
 additional
screening
 were added to the east tower and doors and windows
of the powerhouse were kept ciosed,
 the Hospital could meet
—10—
daytime standards and come very close to meeting nighttime
standards
 (R.
 293-295).
 The cost of such a relocation would be
about $153,000
 (R. 413—418).
Mr. Joseph DeCono,
 a general contractor, testified that a
wooden barrier could be erected for $10,290
 (R.
 440).
 Mr.
 Duane
Thacker, a representative from the manufacturer, testified that
such a barrier could be placed ten feet from the tower without
any adverse effects
 CR. 510).
 Mr. Hearn testified that the
erection of such a barrier along with additional screening and
keeping the doors and windows of the powerhouse closed would
also result in daytime compliance and near compliance at night.
(R.
 295).
The Hospital contends that the cost figures for both re-
location of the tower and construction of a barrier are too low.
The $153,000 figure is argued to be based on overly simplified
construction assumptions and does not include overhead and
profits
 CR.
 428—431).
 With respect to the cost of a barrier,
the Hospital presented testimony that the figure given is for
an undersized barrier and does not include the additional
 costs
of permitting, painting, relocation of electrical highlines and
design responsibilities
 CR.
 443 and Resp.
 Ex.

 The Hospital
argues that the actual cost would be at least $20,917
 (R.
 446—
450).
 The Hospital further argues that a question remains as to
the stability of the wall,
 but the only testimony in this regard
was a general reference by Mr. Wasson, the President of the
Hospital and a non—expert with respect to construction, that
he would have “concern”
 as to whether a barrier “would stand
the weather”
 (R.
 953).
 However,
 Mr. DeCono did not indicate
any technical problem.
The question of burden of proof in this proceeding as it
regards the Section 33(c)
 factors has been briefed by the parties:
both argue that the other has failed to meet his burden of proof
concerning technological practicabliity and economic reasonable-
ness of reducing noise emissions.
 That the parties would dis-
agree as to who has this burden is not surprising since
 the two
leading decisions regarding this issue appear directly contra-
 dictory.
In Processing and Books
 v.
 IPCB,
 64 Ill.2d 68,
 351 N.E.2d,
865
 (1976) the Court held that in prosecuting an odor case,
the Agency did not have the burden of proving the unreasonableness
of respondents’
 conduct in terms of the four Section 33(c)
criteria and that the use of the term “unreasonably” in the
definition of air pollution was simply intended to introduce
into the statute something of the objective quality of the
common law”
 (351 N.E.2d 869).
 In Wells Manufacturing Com~
v.
 IPCB,
 et al.,
 73 Ill.2d 226,
 22 Ill.Dec.
 672,
 383 ~iT~.2d148
(1978), however, the Court reversed the Board
 (over a vigorous
dissent) on the basis that “the Agency failed to establish the
unreasonableness of those odors” as required by the Act (383
N.E.2d 153).
51-108
—11—
Those cases are distinguishable
 from this one and as
 a matter
of fact as well as policy, they should not be applied here.
 On
the facts, both court cases deal with odor nuisances for which
there are no numerical standards against which to measure the
unreasonableness of the odor.
 Violations of numerical noise
standards have been found here.
 As a matter of policy if Wells
were to be followed,
 “a recalcitrant polluter could wait until
 an
 (enforcement
 action is brought and thereby place the burden
upon the Agency to prove that compliance with the regulation is
reasonable...while,..a
 responsible party who seeks a variance...
bears
 the burden of showing that compliance
 is both arbitrary
and unreasonabe”
 (Camp.
 Reply Br.
 19).
 In other words such a
construction of the Act could make it advantageous for a polluter
who has difficulty reaching compliance not to seek a variance.
Finally, when the Supreme Court most recently considered the
question of the burden of proof regarding the Section
 33(c)
criteria in Slager
 v.
 IPCB,
 96 Ill.App.3d 332,
 421 N.E.2d 292
(1981), the Court cited Processing and Books rather than Wells
 in
holding that the burden rested on the respondent,
 rather than
the Agency,
 to introduce evidence on each of these factors.
Thus, the Board concludes that the burden was on the Hospital
to show that compliance is not technologically practicable and
economically reasonable, and that the Hospital has failed to make
that showing.
 Further, even
if
that burden were on the Agency,
the manifest weight of the evidence indicates that technologically
practicable and economically reasonable alternatives exist
 for
reducing emissions.
 The injury detailed in the discussion of
Section 33(c)(1),
 above, clearly indicates more than a trifling
 inconvenience or petty annoyance.
 Not only has this been shown
by the numerical violations which indicate substantial exceedances,
especially at night, but through the considerable testimony of
the nearby residents that the cycling of the west tower is even
more annoying than the “usual” sounds which formed the sole
basis of the numerical violations.
 This has been allowed to
continue despite the more than adequate funds available to the
Hospital to take additional corrective actions and the availa-
bility of several methods of reducing noise.
Section 33(c)(3) of the Act concerns the suitability of
the location of the pollution source.
 In this regard the Board
finds that although the Hospital was constructed slightly prior
to the residential development of the area
 (R.
 262,
 897 and
902),
 the air conditioning equipment was not added until
 1966
(R.
 906), decades after residential development, and the west
tower was not built until
 1978
 (R.
 904—904 and
 909).
 Because of
that,
 the Hospital cannot prevail in its argument that it has
priority of location in that the construction of the noise
sources at issue here was long after the residential nature of
the properties north of the Hospital had been established.
 (See
Wells,
 supra,
 383 N.E.2d 152).
While the Hospital argues that its cooling needs could not
have been met without the west cooling tower
 CR.
 795 and
 910),
51-109
—12—
the placement of that tower
 only
 10
 to
 15
 feet from residential
property, especially
 after
 noise complaints had been received
by the Hospital since 1976 due to
 the
 powerhouse
 and
 the
 east
tower,
 is particularly inappropriate.
 The Hospital also,
 in
effect,
argues that there
was
 no
 other
 place to put the west
tower because of a number of “physical
 and
 economic
 impediments”
(Resp.
 Br,
 72),
 However, the
 Hospital
 has
 only
 succeeded
 in
proving that it would have been less convenient and more expen-
sive to place the tower somewhere
 else.
In sum, noise
 from the Hospital has caused substantial
interference
with the lives
and the enjoyment of property of all
the families
living
immediately north of the Hospital.
 While the
social and economic value of the Hospital
 is unquestioned, that
value is reduced when the Hospital is operated in such a manner
as to cause a
nuisance,
 The placement of a noisy cooling tower
so close to the property of complaining neighbors is particularly
inappropriate.
 However, economically reasonable and technologically
practicable methods of reducing the noise emissions exist.
The Board finds that
the
 Hospital has violated Rules 102,
202 and 203 of Chapter
 8:
 Noise
 Pollution.
PENALTY
In determining a penalty the Board must consider the same
Section 33(c)
 factors as are discussed above.
 In addition, the
Board must consider any other aggravating or mitigating
 factors,
The
Agency
recommends that the Board order the Hospital to
cease and desist and to pay a penalty of not less than $6,000.
That recommendation is based on the degree of injury and the
Hospital’s slow and
ineffective
response in abating the violations.
On the other hand, the Hospital contends that it has acted reason-
ably and responsibly in abating the problem and that “its un-
willingness
 to voluntarily proceed further is neither criminal
nor negligent”
 (Resp.
 Br.
 91).
 The Board notes, however, that no
crimes have been alleged and that negligence is not an element
which need be proven to establish any violations at issue here.
The Hospital’s responsiveness,
 on the other hand,
 is clearly
material to the imposition of a penalty.
As noted
earlier,
 the Hospital
 first became aware of a noise
problem associated with the east cooling tower in 1976 and gave
assurances that the problem would be rectified
 (R.
 17 and 23).
Yet, prior to completion of any remedial measures,
 the Hospital
built and began
operation
of a second tower in June of 1978 which
it placed in close proximity to the first
 CR. 39).
 Noise emissions
were, clearly, a
consideration
in the selection of an oversized
tower and cost the Hospital more than a small, noisier tower would
have, although the amount is not given
 (R.
 480—481).
 Actions
were also taken to keep doors and windows of the powerhouse closed
and to reduce the cycling problem.
 These actions have been
51-110
—13—
somewhat
 effective
 (R,
 189,466 and 469),
 The
 Hospital
 did,
 belatedly,
have
 gear~-reducersinstalled in the east tower in
 1979
 at
 a
 cost
of
 $12,975
 (B.
 26 and Resp.
 Ex.
 29) and in early 1980 had an air
inlet
 attenuator installed
 on
 the
 north
 face
 of
 the
 west
 tower
at
 no
 cost
 to the Hospital
 (R.
 41-44).
Upon learning that apparent
violations
 persisted,
 the
 Hospital
retained
 Mr.
 Yerges in June of
 1980
 as
 a
 noise
 consultant,
 more
than a year after Mr.
 Hearn had recommended that such a consultant
be hired
 (R.
24~26,
51,
 334 and
 Comp.
 Exs.
 12—13),
 He
 suggested
that
 the west tower be run at low speed and
 the
 Hospital
 insists
that
 a
 program was implemented
 to
 assure
 low
 speed
 operation
 of
the
 east
 cooling tower fans
 (R.
 759—760).
 However,
 testimony
indicates
 that high speed
 operation
 is
 necessary
 on
 hot,
 humid
days
 and
 that Hospital personnel
 sometimes
 operate
 the
 towers
 at
high
 speed
 despite directives
 to
 the
 contrary
 CR.
 45—46
 and
 758—761).
Nothing
 further has been done despite
 the
 fact
 that
 violations
have
 continued and both the Agency’s
 and
 the
 Hospital’s
 experts
agree
 that further modifications could be made.
Considering the length of time that has passed since the
Hospital
 first became aware of a
 noise
 problem,
 little
 has
 been
done to remedy it.
 Response has been slow and largely ineffective.
The
 Hospital
 appears to have
 adopted
 a
 philosophy
 that
 if
 it
keeps
 talking
 and
 studying, perhaps the problem will go away.
Hospital expenditures have been minimal and the Hospital’s attitude
appears
 to
 be that it
 is
 enough
 to
 press
 the
 manufacturer
 of
 the
the
 equipment
 to fix the
 problem.
 However,
 the
 noise
 source
 is
 the
Hospital
 and
 it
 is the Hospital’s responsibility to correct the
problem.
 It was not “reasonable and proper
 for the Hospital to
rely
 on
 the parties which were
responsible
 for
 the
 equipment
 and
contract
 performance”
 (Resp.
 Br.
 90)
 until
 construction
 program
completion
 in
 1981 when the west cooling tower operation resulted
in
 noise
 violations upon going into
 service
 in
 1978
 (R.
 904
 and
1013).
 If there was a failure
to
 perform
 the
 contract,
 that
 is
a
 separate
 issue between the
Hospital
 and
 the
 manufacturer
 that
has
 little
 bearing on the
Hospital’s
 responsibility
 to
 its
 neigh-
bors.
Such
 dilatory and ineffective actions
 are
 only
 encouraged
if
 no
 penalty
 is assessed when enforcement actions are finally
taken.
 Therefore,
 a penalty is appropriate to encourage compliance
with
 the
 act.
 While the injury caused has not been
 great
 in
magnitude,
 it has been substantial and it increases with each day
that violations are allowed
to
 continue.
 The
 Board
 finds
 that
 a
penalty
 of
 $2,500 is appropriate.
 Further,
 since the Hospital
is “unwilling to voluntarily
proceed
 further”
 and
 since
 the
violations
 continue, the
Board
 will
 order
 the
 Hospital
 to
 cease
and
 desist,
 making
 further
actions
 involuntary.
 The
 Board
 will
not,
 however, order any particular actions since a range of
options
 appear available.
This Opinion constitutes the Board’s
 findings
 of
 fact
 and
conclusions of law in this matter.
