Hearings were held in this matter
on
 February
 26 and
March
 12,
1982.*
 At the brief first hearing,
 at which no members of the
public were present,
 the Agency presented the testimony of
 Hele~-i
Lai and tendered its Group Exhibit
 1,
 a copy of its record,
 and
Exhibit
 2,
 a topographical map.
 At the March hearing,
 at which
members of the public were present, Miss Lai was present for
cross examination and De Pue area residents Donald f3osnick,
Kathryn Zawacki and Eileen Baily presented testimony on behalf
of the Agency concerning the stream receiving Mobil’s discharge.
Mobil presented no evidence, but moved to continue the hearing
and made an offer of proof as
 to what its witnesses
 (not then
present) would testify.
 The motion and offer were denied.
The Hearing Officer also ruled upon Mobil’s March
 9 Motion
to Admit and to Exclude Materials from Agency Record.
 Following
the arguments of counsel,
 the motion was denied as
 to all but
one document, and Agency Group Ex.
 1 was admitted
 (as was
 Ex.
 2).
Mobil did not file an opening brief.
 In response to the
Agency’s May 24, 1982 brief,
 Mobil sought review of various
Hearing Officer rulings and arguably for the first time raised
the issue of the Agency’s lack of compliance with Section 309.108
formerly
 Rule 905 of Chapter 3,
 citing Olin Cg~p~
 v.
 IEPA,
PCB 80—126, February 17,
 1982.
 Pursuant to leave granted by the
Board August 18,
 1982,
 the Agency’s supplemental brief was filed
September
 1 and Mobil’s
 September 13.
Prior to deciding the contested issues,
 the
 Board
 notes
that
 the
 Agency
 has
 agreed
 to
 revise
 the
 “other
 contaminants”
condition
 concerning
 each
 outfall
 in
 accordance
 with
 the
 Board’s
decision in Caterpillar Tractor Co.

 1981.
THRESHOLD ISSUES
Agency Record As Filed
Agreement having been reached at hearing
 as
 to most items
specified in its March
 9,
 1982 motion,
 Mobil contends that four
items should be
 stricken from the Agency record.
 The first
 two
are letters of November
 6,
 1978 and January 19,
 1979 indicating
that lime was being added to the cooling water stream.
 These
were admitted, over relevancy as well as general objections
noted below.
 The next
 is a memorandum dated February 23,
March
 23, and May 12,
 1977 regarding an inspection of Mobil’s
facility and that of the New Jersey Zinc Corp.
 This was excluded
as it predated Mobil’s application for the instant permit.
 The
final
 item is a list of names of persons present at a July 11,
*As the transcripts were not sequentially numbered, the
February hearing transcript is referred to as
 “iR.”,
 and the
March
 are as “2R.”.
50.168

1979 meeting between Mobil and the Agency.
 No specific ruling
was made as to this item.
 Mobil’s general objections are that
1) existence of these items were not disclosed prior to permit
issuance,
 2) there is no indication as to when specific items
were included in the Agency record,
 and 3)
 there
 is no indication
of the extent to which the Agency relied on a particular document.
The Board has consistently stated that,
 for its permit
review to be meaningful,
 “the Agency record is
 to include all
material
 and relevant facts upon which the Agency relied in
making a determination” County~f
LaSalleetal,
 v,
 IEPA,etal.,
PCB 81—10,
 March
 4,
 1981.
 Error,
 if any,
 should be made on the
side of inclusion of materials, rather than exclusion of them.
The Board does not construe Section 105.102(b)(5)
 formerly
Procedural Rule 502(a) (5)
 or Section 309.109(a)
 formerly
 Rule
906(a)
 of Chapter
 3
 as
 a limitation of the items to be included
in the Agency’s record,
 if relied upon;
 rather these
 rules
establish the minimum amount of information to be considered by
the Agency and presented to the Board.
If Mobil’s other arguments were
 to be accepted,
 and the
Agency were to be required in every case to state specifically
when (already dated)
 items are included in a record,
 to assign
each document some sort of rating for degree of reliance, and
then to disclose the entire file to
 an applicant
prior to
permit
issuance,
 an already cumbersome permitting process would become
a nightmare of useless bureaucratic paper shuffling.
 The Board
finds that all of the above items were properly included in the
Agency record.
 As to the relevancy of the 1977 inspection memo-
randum, the Board
 finds that the historical overview presented
of the facility could properly have been relied upon.
Statement of Basis of Permit Conditions
After filing
 its permit renewal application on October 20,
1978, Mobil neither objected to,
 nor commented on the Agency’s
initial Proposed Draft Permit and Joint Public Notice/Fact Sheet
sent out on December 12,
 1978.*
 A second and quite different
 Proposed Draft Permit and Joint Public Notice/Fact Sheet was
issued on April
 6,
 1979.
 Mobil responded on May
 4,
 1979,. with
written objections as to certain conditions the Agency proposed
to include in the NPDES Permit, with inquiries as to why such
conditions were being included, and with factual information
supporting its objections (Agency Rec.
 15).
 Mobil thereupon
requested and the Agency agreed to an informal meeting involving
*Item
 8 of the Agency’s Index entitled “Summary of Agency
Record
 (Agency Rec.
 8)
 refers to this Proposed Draft Permit and
Joint Public Notice/Fact Sheet,
 but this was omitted from the
Agency Record on appeal filed with the Board on November
 6,
 1979.
This should have been included in the Agency Record,
 but the
Board finds that failure to do so does not ammount to prejudicial
error.
50-169

representatives
 of
 both
 parties
 in
 order
 to
 discuss
 and
 attempt
to resolve these objections
 (Id.
 16).
 This meeting occurred on
July 11,
 1979 as reflected in the correspondence between the
parties
 (Id. 17,
 19);
 further, certain statements were made based
upon this informal meeting regarding certain contested items,
 specifically:
°pHwould be deleted as a parameter upon installation
by Mobil of the C.I.L, cooler to replace
existing
sulphuric acid cooling coil;
°theAgency opposed in principle allowing Mobil credit
for background
 TSS concentrations in its outfall
 001
which are present in the intake water drawn from the
Illinois River solely because of the presence of
non-process incidental plant streams in the non—contact
cooling water discharge irrespective of whether any
measurable amounts of TSS are contained in such streams;
°theAgency agreed to consider characterizing the
unnamed ditch so as to require that Mobil comply with
standards for purposes of its outfall
 002, and to
characterize Negro Creek as the “receiving water” for
purposes of complying with applicable water quality
standards
 (Id.
 19).
The Agency then issued the final NPDES Permit on September 7,
1979
 (Id.
 2).
 This did not include the modifications,
 The permit
reflected the Agency’s subsequent determination that no quali-
fication for equipment replacement was to be made concerning pH,
that no TSS background credit should be given,
 and that the
unnamed ditch should not be classified as an “industrial ditch”.
No accompanying statement for its actions was provided
 regarding
these, or any other issues.
Section 309.108
 (formerly Rule 905 of Chapter
 3) provides
 in
pertinent part that:
“Following the receipt of a complete application for an NPDES
Permit,
 the Agency shall prepare a tentative determination.
 Such
determination shall include at least the following:
a)
b)
 If the determination is
 to issue
 the permit,
 a draft
permit
 containing:
1—2)
3)
 A
 brief
 description
 of
 any
 other
 proposed
 special
conditions
 which
 will
 have
 a
 significant
 impact
 upon
 the
discharge.
50-170
5
c)
 A statement of the basis
 for each of the permit
conditions listed in Section 309.108(b),***”
As noted, the Agency has provided no ~uch statement of basis
for any condition contained in the permit.
 Mobil therefore
argues that this action should be remanded based on Olin, ~p~ra.
Olin involved a permit condition requiring a facility process
evaluation to determine the presence or absence of any of 129
toxic pollutants.
 Olin contended that it could not determine the
basis of the condition until after the appeal was filed, affording
it access to the Agency Record and discovery.
 The Board found
that:
“Had the Agency included a statement of the basis of the
special conditions with the draft permit,
 Olin could
have refuted the basis
 in its comments
 on.
the draft.
A proper record for Board review would have resulted.
The Board holds that Rule
 905(c) required a statement
of basis of the FPE condition in this draft permit”
(Id at 5).
The permit was therefore remanded.
The Agency argues that Olin is distinguishable,
 in that here
a)
 a “statement of basis” was provided by information contained
either in the Joint Public Notice/Fact Sheets or at the July 11
meeting,
 and b) because of this, Mobil had opportunity to submit
any relevant inf9rmation challenging
 these conditions prior to
permit issuance.
 (The Agency reviewed each of the contested
conditions
 in its brief, which discussion will not be set forth
here.
 See Agency Supp.
 Br. of Sept.
 1,
 1982 at 4-6).
The Board
 finds that the intent,
 if not the letter, of
Section 309.108 was satisfied in this case, that the record
before the Board has not been adversely affected, and that Mobil
has suffered no prejudice.
 Accordingly remand of this action
on this ground would not be
 in the interests of administrative
economy.
‘Mobil also cites federal NPDES permit regulations
 found
at 40 CFR §124.17(a).
 In summary this requires states issuing a
final permit decision to state reasons for change between draft
permits and final permits, and to respond to significant comments
on draft permits.
 The federal regulation has no direct analog
in Board regulations,
 and so is not controlling.
2The Board also notes that the lack of a statement of basis
was raised by Olin in its initial appeal for review, whereas Mobil
has raised this issue for the first time by way of response brief.

 (8):
“The

 sentence

refers

 (p.

No
 issues
 of
 fact,
 as
 opposed
 to
 issues
 of
 law,
 were
 disputed
at
 the
 Agency
 level.
 Failure
 to
 submit
 data
 does
 not
 amount
 to
a factual dispute.
 Therefore the Board
 finds that Mobil
 is not
entitled
 to
 a
 de
 nova
 hearing.
THE
 CONDITIONS
Outfall
 001
Section
 304.103
 and
 TSS
 Background
 Credit
Section
 304.103
 “Background
 Concentrations”
 states
 that
“Because
 the
 effluent
 standards
 in
 this
 Part
 are
 based
upon concentrations achievable with conventional
 treat-
ment
 technology
 which
 is
 largely
 unaffected
 by
 ordinary
levels
 of
 contaminants
 in
 intake
 water,
 they
 are
absolute
 standards
 that
 must
 be
 met
 without
 subtracting
background
 concentrations.
 However,
 it
 is
 not
 the
50-172
7
intent of these regulations to require users to clean
 up
contamination caused essentially by upstream sources or
to require treatment when only traces of contaminants
are added to the background.
 Compliance with the
numerical effluent standards
 is therefore not required
when effluent concentrations in excess of the standards
result entirely from influent contamination, evaporation,
and/or the incidental addition of traces of materials
not utilized or produced in the activity that is the
source of the waste.”
In the second draft permit,
 the Agency did not provide
background credit for TSS as it did for fluoride and ammonia.
Mobil’s permit data showed influent concentrations of 59.2 mg/i,
but effluent concentrations of 39.7 mg/i based on monthly grab
samples
 (Agency Rec.
 4,
 p.
 11—6).
 At the July 11,
 1979 meeting
the Agency indicated that its disallowance of background credit
was based on the addition of internal plant waste streams to
non—contact cooling water (Agency Rec.
 19,
 p.
 2).
 Mobil argues,
first, that the Board must define “traces”, and then that Mobil
must be allowed to submit evidence of the quantity of TSS
involved
 in each added waste
 stream.
The Agency cites a few cases involving background credit
rulings:
 two in which background credit was denied,
 East
St. Louis and Interurban Water Co. and Alton Water Co.
 v.
 IEPA,
PCB 76—297,
 298
 (consolidated), February 17,
 1977 and Texaco,
 Inc.
v.
 IEPA,
 PCB 77—154, December
 8,
 1977, and one in which background
credit was allowed even though materials were being added to
cooling water Central Illinois Public Service
 v.
 IEPA,
 PCB 74—145,
148,
 149
 (consolidated).
 The Agency argues that CIPS should be
abandoned,
 for reasons not entirely clear.
The Agency further argues that
 it would,
 in any case, have
been unable to make a determination based on the information
provided by Mobil
 as
 a)
 no evidence was presented indicating
 the
amount of suspended solids added relative to background levels,
and
 b)
 it has questions concerning the sampling methodology used
in producing the influent/effluent concentrations provided.
The Board need not reach the questions of further defining
“traces”, or of repudiating CIPS.
 Based on the lack of infor-
mation at the time of permit issuance, the Agency’s denia1 of
background credit was proper.
 (The Board notes that much of the
lacking data was provided in PCB 82-18,
 p.
 2—5,
 in which a TSS
variance was granted.)
ph
 Limitation
The pH limitation itself is that requested by Mobil.
 As
 it
relates to the operation at the time of application,
 Mobil
 is
apparently concerned about the “limited at all times”
 language,
50-173
8
but does not explain the source
of
its
 problem.
 The
 Agency
 notes
that
 Mobil
 did not oblect to
 inclusion
 of
 this
 language
 in
 its
draft
 permit.
 It
 ‘further
 notes
 the
 words
 “as
 follows”
 appear
after
 the
 limitation
 language,
 and
 that
 “as
 follows”
 refers
 to
specific
 limitations
 and
 the
 sampling
 frequencies
 by
 which
compliance
 is judged.
It
 would
 appear
 then
 that;
 Mobil ‘s
 concern
 relates
 to
 Agency
failure
 to
 provide
 for
 deletion
 of
 the
 parameter
 upon
 installation
by
 Mobil
 of the CiL
cooler
to
replace
 existing
 sulphuric
 acid
cooling
 coil
 (Agency
 Rec.
 19).
 While
 deletion
 of
 the
 Chapter
 3—
based
 parameter
 would
 he
 a
 proper
 subject
 of
 a
 permit
 modification
once
 replacement
 actually
 occurred,
 the
 Board
 finds
 that
 the
Agency
 was
 justified
 in
 including
 the
 condition
 as
 it related to
existing
 equipment.

Mobil
 does
 not,
 address
 this,
 while
 the
 Agency
 agrees
 that
the
 request
 to
 add

 has
 merit,
 It
 notes
 that
 this
 does
 not,
however,
 effect
 the
 validity
 of
 the
 permit
 as
 issued.
 The
omission
 is
 upheld~ as the Agency
 is
 technically
 correct,
 although
the

 should

 remedied.
Semi—Annual Contaminant
 Monitorinq
The
 condition,
 requiring
 monitoring
 for
 contaminants
 listed
in
 Section
 304.
 :L24,
 was imposed
 as
 to both
 outfails,
 and
 was
contained
 in
 the draft permit.
 Mobil
 commented
 that
 many
 of
these contaminants were not characteristic of its
 discharge,
 but
provided no sampling data
 in support
 of
 the
 claim.
The Agency supports the conditions
 on
 the basis of its
authority under §39(b)
 of
 the
 Act
 to
 impose
 conditions
 as
 “may
be required to accomplish the purposes and provisions of this Act”.
It argues that such access to continuing monitoring data allows
it to verify information
in
 the permit application concerning the
nature of the discharge,
 and to determine whether
 the
 nature of
the discharge changes.
 As this condition lies within the Agency’s
authority,
 and
 as
 Mobil
 did
 not
 avail
 itself
 of
 an
 opportunity
to support its general objection with data,
 the condition is
sustained.
Outfall
 002
Unnamed Pri
buta~2~a
 Creek
Ground seepage from Mobil’s gypsum pond flows into an unnamed
ditch
 ‘tributary
 to
 Negro
 Creek,
 which
 is
 ‘tributary
 to
 the Illinois
River
 (see PCB
 82—18.. p.5).
 Were this ditch
 found to be an
industrial
 ditch, effluent limits and hence sampling points would
be established at the point where the ditch enters Negro Creek,
50-174
9
rather than at the point of Mobil’s discharge.
 The unnamed ditch
does not join Negro Creek within the limits of Mobil’s property,
but instead flows past two homes about a mile downstream of
Mobil’s discharge before
 flowing into the creek.
In determining whether a stream is an industrial ditch as
opposed to a “water of the State”,
 the Board
 looks to three
criteria,
 as set out in IEPA v.
 Jobe,
 PCB 80—214,
 January
 7,
 1982:
1.
 Whether the stream or ditch is a natural depression
or waterway or is instead artificially constructed or maintained:
2.
 Whether there is public acess to or use of the waters;
and
3.
 Whether the waters support aquatic
 life.
Mobil does not argue that the criteria are not satisfied, arguing
only
 that
 it had not been informed of the classification prior
to issuance.
 The condition Is sustained (Citizen testimony
concerning the nature of the stream is set out
 in PCB 82-18,
 p.
 7).
Compilance Schedule
No delayed compliance schedule concerning the gypsum pile
discharge was included, based on the Agency’s legal interpretation
that Section 309.148(f) prohibited it from doing
 so.
 The section
provides that:
“The Agency may establish schedules of compliance
 in
NPDES Permits pursuant to applicable federal require-
ments which may be earlier or later than deadlines
established by otherwise applicable regulations
 of the
Board, provided that all schedules of compliance shall
require compliance at the earliest reasonable date.
However, the Agency shall not issue an NPDES Permit
containing a schedule of compliance beyond July
 1,
 1977,
or any other compliance date established by federal
 law,
to any applicant who is not in compliance with,
 or who
has not obtained a variance from applicable Illinois
Water Pollution Regulations, or who has not been ordered
to apply for and obtain all necessary permits in an
appropriate Board enforcement action,
 for which the
deadline for compliance occurred before the effective
date of these NPDES Regulations.”
Section 301(a)(1)(A) of the Federal Water Pollution Control
Act set forth a deadline of July 1,
 1977 for compliance with the
BPT standard set forth in
 40 CFR §418.10.
 As this deadline had
passed prior to the October 24,
 1977 effective date of the NPDES
regulations,
 the Agency determined that variance relief was neces-
sary before a compliance schedule could issue, as no enforcement
order was outstanding.
50-175
10
Mobil
 argues that a compliance schedule should have been
issued, based on extension of BAT compliance deadlines by 1977
amendments to the Federal Clean Water Act.
While Section 309.148 is admittedly turgid,
 the Agency’s
interpretation is correct.
 Failure to include a compliance plan
and interim standards was not in error.
 (Grant of variance in
PCB 82—18 now allows
 for inclusion of interim standards and a
compliance schedule.)
This Opinion constitutes the Board’s findings of fact and
conclusions of law in this matter.

The Board upholds the permitting decisions made by the
Agency
 in granting NPDES Permit No.
