OPINION
AND
ORDER OF THE BOARD
 (BY SAMUEL T. LAWTON, JR.):
This case was commenced by the Environmental Protection
Agency
 (“Agency”)
 with the filing of a complaint against
Ralston Purina Company
 (“Ralston”) on April
 26,
 1971.
 The
complaint charged Ralston with violation of the Ringlemann
smoke standard of Rule
 3-3.122
 of the Rules and Regulations
Governing the Control of Air Pollution
 (“Rules”), promulgated
pursuant to Section 5-1.2 of the Air Pollution Control Act;
with operation of its boilers in violation of Rule 3-3.112
of the Rules, effective pursuant to Section 49(c)
 of the
Environmental Protection Act (“Act”); causing, threatening,
or allowing the discharge or emission of fly ash into the
environment so as to cause or tend to cause air pollution in
violation of Section
 9(a) of the Act; causing excessive noise
in the operation of its plant on December 18,
 1970,
 so as to
cause, threaten or allow air pollution in violation of Section
9(a) of the Act; creation of odors
 so as to cause, threaten or
allow air pollution in violation of Section
 9(a)
 of the Act;
operating its plant without
 a permit from the Agency in
violation of Section 9(b)
 of the Act; failing
 to submit since
approximately October
 15,
 1967,
 a “Letter of Intent” relating
to its coal fired boilers in violation of Rule 2-2.22 of the
Rules; and failing since April 15, 1968,
 to submit to the Air
Pollution Control Board or to the Agency an air contaminant
emission reduction program
 (ACERP)
 relating to its coal fired
boilers in violation of Rules
 2—2.31(f)
 and 2-2.41 of the Rules.

Ralston operates a large feed manufacturing plant near the
City of Bloomington,
 Illinois,
 in McLean County.
 At this
facility approximately 160 different feeds are manufactured.
The facility also has a soy bean processing plant where soy
bean oil is manufactured or extracted.
 There has been no soy
bean extraction processes at any facility in the area other
than the Ralston operation since 1969
 (R. 126).
 The area in
which the Ralston facility is located is partially industrial
 and partially residential, with a significant public housing
development located nearby.
 This public housing development,
Sunnyside Court, was constructed after Ralston was already
operating, but the area already included houses on at least
two sides of
 the facility
 (R.
 609,
 613-614).
 People who reside
in Sunnyside Court do so because they are assigned there by the
Housing Authority
 (R.
 546).
Before discussing the substantive issues of this case,
there are several preliminary matters which must be first re-
solved.
 Ralston moved to dismiss and strike the complaint
because, Ralston asserts, the allegations of the complaint are
conclusory and insufficient, thereby depriving the Respondent
of his rights to be apprised with exactness and conciseness
as to
 •the respective charges.
 We disagree.
 The complaint
states with adequate specificity those things which Ralston
was charged with doing in violation of the law.
 Accordingly,
we deny the motion to dismiss.
 Ralston also alleges that the
complaint should be stricken because of the nature of the action
which Ralston alleges is quasi-criminal, thereby depriving
Ralston of its right to a fair trial and due process of law.
These precise contentions were rejected by the Illinois
Appellate Court Third District in the case of C.M.
 Ford v.
Environmental Protection Agency
 ;

 Ill.

 (1973);
PCB71-307 and in the Fourth District in the case of Bath,
 Inc.
v. Environmental Protection Agency
 Ill.
 App.
 2d
PCB71—52, 71—244.
A Petition to Intervene in the enforcement proceedings was
filed by the McLean County Economic Opportunity Corporation
(Corporation) and Jane Stiliman
 (Stiliman).
 The Corporation
alleged that it, representing low income individuals living
in the housing project adjacent to the Ralston facilities, may
be adversely affected by Board orders, and that Stiliman,
 an
individual,
 is a resident of the housing project and may also
be adversely affected.
 Intervention was allowed by the Hearing
Officer.
In an attempt to obtain pre-trial discovery,
 Ralston
attempted to take a discovery deposition of Stiliman.
 Although
proper notice was given to Stillman regarding the deposition,
and although the attorneys for both Ralston and Stiliman and
a court reporter appeared for the deposition, she did not
appear.
 Ralston moved to dismiss
the
 intervenors,
 to prohibit
Stillman to testify at any hearings in the matter, and moved
7— 438
—3—
further that the Board censureStillman and charge her costs
for the attempts to take her deposition.
 The Board has no
 censure powers, nor has it power to assess costs in such a
situation.
 However, when
 a party has asked for leave to
intervene and has been granted the privilege of intervention,
that privilege ought not be abused as was done in this case.
Those who intervene and are given notice of depositions
should appear.
 The record indicates that the Corporation
was represented by counsel at the hearings of September
 8
and
 9,
 1971, and that Stiliman testified at the hearing of
September 19, 1972 regarding odor and ash problems related
to the Ralston facility.
 At this later hearing, Corporation
was not represented by counsel.
 We will grant the motion to
dismiss Stillman from the case, but deny the motion as to the
Corporation.
 Stillman’s abuse of our procedures should not
redound to the detriment of Corporation.
 We will not grant
the motion to prevent Stiliman from testifying.
 The Act
requires that citizens be allowed to testify, and we will
therefore allow Stiliman’s testimony to stay in the record.
After the complaint was filed, there was extensive pre-
hearing negotiations between the parties.
 There were two
days of hearings in September of 1971.
 On the third day,
September 10,
 1971, a reported settlement was reached and was
subsequently transmitted to the Pollution Control Board
(Board),which rejected the proposed settlement on November
23,
 1971, because the Agency had not concurred in the settle-
 ment and because there was an inadequate factual foundation
on which the Board could make decision.
 In September of
1972, a second settlement was presented to the Board, which
settlement was again rejected on the basis that there was an
inadequate factual foundation on which to base
 a decision.
On November 28,
 1972,
 a final hearing was held and upon con-
clusion of that hearing,
 all parties rested.
 The proposed
settlement was resubmitted and the parties have asked that
the Board decide the case based on the record it now has.
Certain of the substantive allegations of the complaint
are easily resolved.
 Excessive noise does not constitute air
pollution in violation of Section
 9(a)
 of the Environmental
Protection Act.
 Title VI of the Act contemplates by its very
nature that the control of noise must be implemented by regu-
lation or standard adopted by the Board.
 Accordingly,
Paragraph
 5 of the complaint is dismissed.
Smoke emissions in excess of that allowed by Rule 3-3.122
are alleged to have occurred on June 2,
 1970.
 The deposition
of Robert Hendricks contains pertinent evidence relating to
this charge.
 He estimates that on the day in question,
 he was
on the plant property for approximately 20 minutes and that
for about half that time there were smoke emissions in excess of
 2 on
the Ringlemann Chart.
 Both times given by the witness were
7
—
 439
—4—
estimated.
 The witness did not take his measurements in
accordance with the directions on the Ringlemann Chart, but
he also testified that he
 has taken as many as 60 Ringlemann
readings during his employ with the Agency
 (p.
 23).
 While
it is not necessary that the readings be made with a
Ringlemann Chart,
 or that the readings be made with mathematical
exactitude as relates to the directions on the chart, the
evidence must be greater than that here.
 Although the
witness had made numerous readings in the past,
 there is no
evidence that he was a trained smoke observer, nor was there
any evidence as to any expertise the witness had to make
Ringlemann evaluations.
 Accordingly, we find no violation
of Rule 3—3.122.
The Agency also charged operation of equipment without
a permit in violation of Section 9(b)
 of the Act.
 The
complaint in this case was filed prior to the Board decision
in Environmental Protection Agency v. Southern Illinois Asphalt,
PCB71—3l, in which case the Board held that there could be
no operating permit violations until such time as the Board
had adopted its own operating permit regulations.
 Consistent
with our decision in Southern Illinois Asphalt, we find no
violation of Section 9(b).
The Agency’s allegations regarding the “Letter of Intent”
 (Rule 2-2.22), the Air Contaminant Emission Reduction Program
(ACERP)
 (Rules 2—2.31(f) and 2-2.41)
 and coal boiler operation
violations
 (Rule 3-3.112)
 all depend on whether the Ralston
facility is located in a standard metropolitan statistical
area
 (SMSA).
 If Ralston is located in
 a SMSA,
 its allowable
emission rate is 0.6 pounds of particulates per million BTU
input
 (Rule 3-3.112), and its estimate of 0.79 pounds of
particulate per million BTU input in its “Letter of Intent”
(Complainant Ex.
 7)
 placesthe boilers in excess of the
particulate limits.
 Then,
 the Agency contends, under the
Rules Ralston would be required to file an ACERP describing
how the facility would be brought into compliance.
 The Agency
further contends that the estimated 0.79 pounds per million
BTU is misleading,
 thereby rendering the “Letter of Intent”
invalid.
 The Agency, continuing to construct a house of cards,
claims that even if Ralston is not in an SMSA,
 its estimate
of 0.79
 is so close to the allowable standard of 0.8 pounds
of particulate per million BTU input
 (Rule 2-2.53)
 that
Ralston should have filed an ACERP anyway.
 The Agency bases
this argument on the fact that Ralston estimated that its
coal had a
 5.3
 ash content
 (Complainant Exhibit 7), was
purchased in Illinois
 (Complainant Exhibit
 7), and therefore
would produce more particulates that Ralston so estimated.
However, the Agency neglected to provide any information to
rebut Ralston’s 5.3
 ash content estimate.
 Ralston’s figures
regarding fly ash content and particulate emissions being the
only such figures in the record, we are accepting them.
7—

The Agency contends, despite the definition of SMSA
(“...
 county which has at least one city with a populaiton of
at least 50,000, and the surrounding counties which contain
the suburban areas for these cities.”) contained in Table
 I
of the Rules, that McLean County
 is an SMSA.
 It bases the
contention on the inclusion of Champaign County as an SMSA
in Table
 I, pointing out that neither Champaign nor Urbana
has a population
 of 50,000, but that collectively,
 they do
in fact have
 a population
 in excess of
 50,000.
 The Agency
then states that neither Bloomington nor Normal has a popula-
tion of
 50,000, but, again as Champaign—Urbana, the collective
population exceeds
 50,000.
 Therefore, Ralston
 is located in
an SMSA.
 This apparently reasonable argument must fail for
the simplest of reasons:
 Table
 I contains an exclusive list
of SMSA’s in Illinois, and the Ralston facility is not in an
area included on Table
 I.
 The Board cannot unilaterally
amend duly adopted Rules.
For the above reasons, we find no violations of Rules
2—2.22, 2—2.31(f),
 2—2.41 and 3—3.112.
The record overwhelmingly demonstrated that Ralston caused
air pollution due to odors.
 Several witnesses who either live
in the Sunnyside housing development across the street of
 the
Ralston facility or who work in the neighborhood testified at
the hearing of September 19,
 1972.
 A brief summary of their
testimony regarding odor from the Ralston facility reveals
the severity and duration of those odors.
Dorothy J. Stewart, an official of the Bloomington Housing
Authority, testified that the odor is serious as far as two
blocks away,
 and during hot weather the odor is unbearable and
smells like spoiled food
 (R.
 498).
 Ms. Stewart is in the area
nearly every day
 (R.
 497).
Mr. John L.
 Brown, Director of the Sunnyside project,
simply described the odor as
 “undescribable bad”
 (R.
 501).
Mr. James Herbert,
 an employment counselor who is in the
Sunnyside area frequently described the odor as “worse than
dog food”
 (R.
 570).
Ms. Sharon Hamilton,
 a resident of the project, described
the odor as making both her and her children nauseous
 (R.
 514,
516)
Ms. Jane Stiliman,
 a resident of Sunnyside and also a
Director of the project, described the odor as follows:
“terrible.
 There’s no describing it”
 (R.
 532).
Ms. Patricia Wannemacher, who worked in an office in the
area, described the odor as
 “pretty bad”
 (R.
 536)
 and “very
offensive”
 (R.
 540)
7—441
—6—
Mr.
 John H.
 Porter, Jr. testified that odor, noticeable
on an occasional basis, was “a kind of heavy opressive kind
of smell that would tend to make me gag”
 (P.
 560)..
Mr. Earl Johnson testified that he had been a resident of
Sunnyside Court but obtained a doctors certificate allowing
him to move from the public housing development.
 The odor when
he lived at Sunnyside,
 stated Mr. Johnson,
 “smelled like.. .a
bunch of old bones”
 CR.
 580).
Ms. Marian Jones testified that the odor was “like some-
body cooking huge amounts of garbage or something”
 (R.
 595).
Ralston attempted to rebut the above testimony with
evidence that other facilities in the area, namely
 a sewage
treatment plant, was the cause of many of the odors.
 However,
the other witnesses were able to distinguish between Ralston’s
odors and other odors in the area
 (R.
 504,
 520,
 540).
Ralston also asserted that their facility was located in the
area prior to the Sunnyside Court housing project
 (See
testimony of Mr.
 Robert A. Hopkins,
 P.
 608—614), but while
priority of location is a factor to be considered by the Board
pursuant to Section 33(c) (1)
 of the Act, operating
 a.
 .~tus-
trial facility in
 a mixed residential, agricultural ai.~
industrial area is not an excuse to cause residents of that
area to bear the unconscionable burdens that they were forced
to bear for so long.
The odor and dust nuisances had in fact remained unabated
for approximately 20 years
 (P.
 552).
 Hopefully, the proposed
and by now partially implemented compliance program set forth
in the settlement will in fact have abated the odor and dust
nuisances.
The evidence supporting the Agency’s allegation of
excessive fly—ash from the Ralston facility causing air pollu-
tion in violation of Section
 9(a) of the Act is also well
supported by the evidence in the record.
 There
 is overwhelm-
ing evidence that there was much dust in the area,
 and that
the dust did create a serious cleaning problem and an often
serious health hazard, and that the dust in fact was attribut-
able to the Ralston facility described by residents and workers
in the area at the September 19, 1972 hearing.
The compliance program,
 set forth in Paragraphs 3-8 of the
Stipulation for Settlement, is as follows:
 Respondent’s boilers
have been converted from coal to oil,
 and certain control
equipment has been installed pursuant to Agency permit,
 thereby
eliminating any particulate emissions problems
 (Paragraph
 3);
certain noise abatement practices have already been instituted
(Paragraph 4); fish processing,
 a significant odor producing
activity, has ceased and will not resume in the future
 (Para—

graph
 5);
 internal housekeeping practices designed to improve odor
problems have been submitted
 to the Agency for the Agency’s approval
or modification
 (Paragraph 6); the vent stacks from the soy bean
flake dryer operation will be modified to eliminate odor nuisance
from that source (Paragraph
 7) and Respondent generally promises
to
 comply
 with
 the
