Plain-English summary

General Motors Corporation's Delco Moraine North and South Plants in Dayton, Ohio, held federal portions of RCRA permits for manufacturing facilities that produced and stored hazardous waste. GMC challenged corrective-action requirements, interim-measures and permit-modification provisions, definitions, inspection photographs, split samples, severability, and the South Plant permit term and deletion of one condition. The Board remanded both permits, ordering changes that included correcting North Plant report-timing inconsistencies, following formal modification procedures for interim measures, removing unauthorized permit language, tailoring a planned-operations notice provision, guaranteeing split samples, and deleting an inadvertently retained South Plant condition. It granted review on whether the Region could revise interim submissions without formal permit modification and denied review on the other challenges.

RCRA Consolidated Appeal Nos. 90-24, 90-25

ORDER DENYING REVIEW IN PART, REMANDING IN PART,
AND GRANTING REVIEW IN PART

Decided November 6, 1992

Syllabus

This order consolidates two petitions for review filed by General Motors Corpora-
tion (GMC). The petitions seek review of the federal portion of two permits issued
by Region V under the 1984 Hazardous and Solid Waste Amendments to the Resource
Conservation and Recovery Act. The first petition seeks review of a permit for GMC’s
Delco Moraine Division North Plant in Dayton, Ohio (North Plant), and the second
for GMC’s Delco Moraine Division South Plant, also in Dayton, Ohio (South Plant).
The North Plant petition asks that review be granted with respect to: (1) the permit’s
definition of “solid waste management unit” (SWMU); (2) the allegedly improper des-
ignation of SWMUs; (3) the imposition of corrective action requirements at a former
chrome plater site; (4) the allegedly overly broad corrective action requirements; (5)
the permit’s interim measures provision; (6) the permit provisions allowing the Region
to modify interim submittals; (7) the Region’s authority to modify a permit under
RCRA § 3005(c)(3); (8) the permit provision requiring GMC to provide notice of changes
in plant operations; (9) the permit’s definition of “Hazardous waste”; (10) the permit’s
potential for allowing the misuse of photographs taken during EPA inspections; (11)
the permit’s failure to guarantee GMC’s right to split samples; and (12) the permit’s
severability provision. The South Plant petition raises issues 1, 6-8, and 10-12 noted
above. In addition, the South Plant petition seeks review of: (1) an alleged inconsist-
ency in the duration of the permit; and (2) the Region’s failure to delete a permit
provision even through it had agreed to do so.

Held: Both permits are remanded to the Region. With regard to the North permit,
the Region is ordered to: (1) modify the permit to correct inconsistencies in the timing
for the submission of various reports and the items to be included in those reports
and (2) ensure that Agency-initiated modifications to incorporate interim measures
comply with the modification procedures at 40 C.F.R. § 270.41. With regard to both
the North and South plant permits, the Region is ordered to: (1) remove language
from permit condition I.B. allowing the Region to modify the permit “as determined
necessary to protect human health and the environment, pursuant to Section 3005(c)(3)
of RCRA”; (2) tailor Permit Condition I.D.10, if necessary, to fulfill the Region’s HSWA
obligations; and (3) add language to the permit guaranteeing GMC’s right to split
samples. Further, with regard to the South Plant permit, the Region is ordered to
delete permit provision I.D.18 which was inadvertently included in the final permit.

The petition for review of the North Plant permit is granted with regard to
GMC’s contention that the provisions of the permit allowing the Region to revise
or require GMC to revise interim submissions prepared during the corrective action
process without using the formal permit modification process violates due process.
Review is denied with regard to all other issues raised in both petitions.

Before Environmental Appeals Judges Nancy B. Firestone,
Ronald L. McCallum, and Edward E. Reich.

Opinion of the Board by Judge Firestone:

I. BACKGROUND

This Order consolidates two petitions for review filed by General
Motors Corporation (GMC).1 Each petition is dated October 29, 1990,
and each seeks review of the federal portion of a permit issued
by Region V under the 1984 Hazardous and Solid Waste Amendments
(HSWA) to the Resources Conservation and Recovery Act of 1976
(RCRA), 42 U.S.C.A. §§ 6901-6992k.2 The first petition seeks review
of a permit for GMC’s Delco Moraine Division North Plant in Dayton,
Ohio (North Plant), and the second for GMC’s Delco Moraine Division
South Plant, also in Dayton, Ohio (South Plant). Both permits are
dated September 28, 1990.

GMC’s North Plant is a manufacturing facility producing disc
brake systems, transmission components, and friction materials. The
South Plant produces engine parts, brake shoes, and brake shoe
linings. Hazardous wastes produced by both Plants are stored in
a container storage area prior to their removal off-site.

A RCRA Facility Assessment (RFA) at the North Plant identified
a total of 123 Solid Waste Management Units (SWMU’s). The only
identified release requiring corrective action, however, is located at
a former chrome plater site. EPA listed the chrome plater site as
“a potential SWMU.” Chromium, including hexavalent chromium was
detected in the subsoil and ground water beneath this site. GMC
has initiated certain remediation efforts in response to these releases
in cooperation with State and local officials.

1 At the time this appeal was filed, the Agency’s Judicial Officers provided support
to the Administrator in his review of permit appeals. Subsequently, effective on March
1, 1992, the position of Judicial Officer was abolished and all cases pending before
the Administrator, including this case, were transferred to the Environmental Appeals
Board. 57 Fed. Reg. 5321 (Feb. 13, 1992).

2The non-HSWA portion of the permit was issued by the State of Ohio, an author-
ized State under RCRA § 3006(b), 42 U.S.C. § 6926(b).

VOLUME 4
336 ENVIRONMENTAL ADMINISTRATIVE DECISIONS

There are no known releases of hazardous waste or hazardous
constituents from the South facility and no corrective action is re-
quired under the permit. Most of the issues raised in GMC’s petition
for review of the South Plant permit are identical to those raised
in its petition for review of the North Plant permit. These include
issues 1, 6-8, and 10-12 discussed below. The South Plant Petition
also raises two additional issues which are discussed at Part III
below.

II. DISCUSSION

Under the rules governing this proceeding, a RCRA permit ordi-
narily will not be reviewed unless it is based on a clearly erroneous
finding of fact or conclusion of law, or involves an important matter
of policy or exercise of discretion that warrants review. See 40 C.F.R.
§ 124.19; 45 Fed. Reg. 33,412 (May 19, 1980). The preamble to section
124.19 states that “this power of review should be only sparingly
exercised,” and that “most permit conditions should be finally deter-
mined at the Regional level * * *.” Id. The burden of demonstrating
that review is warranted is thus on the Petitioner. See In re Pollution
Control Industries of Indiana, Inc.. RCRA Appeal No. 92-3, at 3
(EAB, August 5, 1992); In re Sandoz Pharmaceuticals Corp., RCRA
Appeal No. 91-14, at 3 (EAB, July 9, 1992).

1. Definition of Solid Waste Management Unit (SWMU)

GMC argues that the definition of a SWMU in both the North
and South Plant permits is overly broad and contrary to Congres-
sional intent at the time RCRA § 3004(u) was enacted. We disagree.
The North Plant permit defines a SWMU as:4

[a]ny discernable unit at which solid wastes have
been placed at any time, irrespective of whether the
unit was intended for the management of solid or
hazardous waste. Such units include any area at a
facility at which solid wastes have been routinely
and systematically released.

3RCRA § 3004(u) provides that permits issued after November 8, 1984, shall re-
quire:
[C]orrective action for all releases of hazardous waste or constitu-
ents from any solid waste management unit at a treatment, stor-
age, or disposal facility seeking a permit under this subchapter,
regardless of the time at which waste was placed in such unit.
4Contrary to GMC’s assertions, the South Plant permit does not define a SWMU.

VOLUME 4
GENERAL MOTORS CORPORATION, DELCO MORAINE 337
DIVISION, ET AL.

Permit Condition III.B. Although neither the statute nor the regula-
tions expressly define “SWMU”, the terms “solid waste management”
and “unit” are defined. “Solid Waste Management” is defined as “the
systematic administration of activities which provide for the collec-
tion, source separation, storage, transportation, transfer, processing,
treatment, and disposal of solid waste.” RCRA § 1004(28), 42 U.S.C.
§6903(28). The term “unit” refers to any contiguous area of land
on or in which waste is placed. See 47 Fed. Reg. 32,289 (July 26,
1982). Based upon these definitions, “the term ‘SWMU’ plainly in-
cludes any unit (contiguous area of land on which waste is placed)
used for solid waste management (the systematic collection, source
separation, storage transportation, transfer, processing, treatment or
disposal of solid waste).” In re Morton International, Inc. (Moss Point,
Mississippi), RCRA Appeal No. 90-17 at 4 (Feb. 28, 1992). In addi-
tion, the legislative history of section 3004(u) indicates that the term
“SWMU” embraces any unit in which solid waste management actu-
ally occurred regardless of whether such management was intended.
See H.R. Rep. No. 198, 98th Cong., 1st Sess. Part 1, 60 (1983) (Under
RCRA § 3004(u), the Agency should examine all units “from which
hazardous constituents might migrate irrespective of whether the
units were intended for the management of solid and/or hazardous
wastes.”); 50 Fed. Reg. 28,712 (July 15, 1985). GMC’s arguments
to the contrary notwithstanding, the permit’s definition of a SWMU
is consistent with both the statutory definition of “solid waste man-
agement” and the legislative history concerning units intended for
regulation under RCRA § 3004(u).5

The legislative history of RCRA § 3004(u) states that “[t]he term
‘unit’ is intended to be defined as in the preamble to EPA regulations
published on July 26, 1982, and as further defined in the future.”
H.R. Rep. No. 198, supra, at 60. GMC contends that SWMU’s are
limited to the types of units specifically listed in the preamble to
the Agency’s July 26, 1982 regulations referred to in the House Re-
port. These include surface impoundments, waste piles, land treat-
ment units and landfills. See 47 Fed. Reg. 32,281 (July 26, 1982).
As the Administrator has previously held, however, “nothing in the
legislative history permanently confines ‘unit’ to a fixed list of devices
or regulatory categories.” In re Shell Oil Company, RCRA Appeal
No. 88-48 at 5 n.4 (March 12, 1990). In fact, the House report

5The permit’s definition of “SWMU” also appears consistent with the definition
in the proposed Subpart S corrective action proposal. The Subpart S proposal defines
“SWMU” as “[a]ny discernible unit at which solid wastes have been placed at any
time, irrespective of whether the unit was intended for the management of solid
or hazardous wastes.” 55 Fed. Reg. 30,808 (July 27, 1990). See also RCRA Facility
Assessment Guidance, OSWER Dir. 9502.00—-5 (October 9, 1986) at 1-3.

VOLUME 4
338 ENVIRONMENTAL ADMINISTRATIVE DECISIONS

specifically states that the Agency may further define the term “unit”
as necessary to implement the goals of the RCRA program. See H.R.
Rep. No. 198, supra, at 60. GMC’s arguments to the contrary in
both the North and South Petitions are therefore rejected.

2. Application of SWMU Definition

After conducting a RCRA facility assessment, the Region identi-
fied a total of 123 SWMUs at the North Plant facility.6 GMC contends
that even under the permit’s definition of a SWMU, many locations
have been improperly designated. Specifically, GMC states:

[Ml]any of these locations are not discernable units,
are items of equipment which have been entirely re-
moved from service, are inactive or were never placed
in service, are permitted under the Clean Water Act
or the Clean Air Act, or are areas or equipment
which do not handle either hazardous wastes or ma-
terials containing hazardous constituents, do not
handle wastes at all or have no release or potential
for release.

Petition for Review at 7. In an attachment to its Petition (Exhibit
A), GMC lists the 123 SWMUs and indicates which of above-noted
objections applies to each SWMU. None of these specific objections,
however, were raised during the public comment period. Review is
therefore denied.

In comment number 35 on the draft permit, GMC stated:

[GMC] does not agree with the designation of
SWMUs and areas of concern in Attachment I. We
previously questioned inclusion of many of these
areas and pieces of equipment. However, we have
received no explanation justifying their designation
as SWMUs or areas of concern.”7 Therefore, we re-

See Permit Attachment I (List of Solid Waste Managements Units (Including
Potential Solid Waste Management Units) and Areas of Concern).

7™GMC is apparently referring to a letter from GMC to Region V dated May
31, 1990 (prior to issuance of the draft permit). In that letter, GMC expressed disagree-
ment with the way SWMU had been defined by EPA for the purposes of the RCRA
Facility Assessment. GMC did not object to any specific SWMU designation but argued
(as it did in its petition) that “until a legal definition is available, the term SWMU
should parallel the traditional hazardous waste management units as identified in
the preamble to the 1982 codification regulations.”

GENERAL MOTORS CORPORATION, DELCO MORAINE 339
DIVISION, ET AL.

serve our right to dispute these designations if, in
the future, EPA proposes specific requirements re-
garding them. (emphasis added).

GMC did not contest any specific designation nor did it request any
changes to the draft permit. Rather, GMC indicated that it would
only dispute the SWMU designations if, at some point in the future,
the Region imposed corrective action requirements at any of these
locations.8 These general comments combined with the possibility
of future objections fail to satisfy GMC’s obligation to provide all
reasonably available arguments supporting its position during the
comment period. If an issue is reasonably ascertainable during the
public comment period, the issue must be raised at that time if
it is to be preserved for review. See 40 C.F.R. §§ 124.13 & 124.19(a).
This requirement ensures that the Region will have an opportunity
to address potential problems with a draft permit before the permit
becomes final. See Shell Oil Company, supra, at 3 (“These rules
help to ensure that the Region has an opportunity to address any
concerns raised by the permit, thereby promoting the Agency’s long-
standing policy that most permit issues be resolved at the Regional
level.”). Because GMC’s current objections to the specific SWMU des-
ignations were not raised during the comment period, review is de-
nied.

3. Corrective Action Requirements at the Former Chrome Plater Site

GMC argues that it was arbitrary and capricious for the Region
to impose corrective action requirements9 at the North Plant’s

8No such requirements have been imposed. We also note that the Region has
agreed to consider future comments by GMC regarding specific units designated as
SWMUs. “If GMC presented U.S. EPA with any information indicating that any of
U.S. EPA’s designations are inappropriate, U.S. EPA remains willing to modify the
permit as appropriate.” Region’s Response at 7, 10.

$Generally, corrective action requirements consist of several steps. The first step
is usually the RCRA Facility Assessment (RFA), during which the Agency attempts
to identify actual and potential releases of hazardous waste or hazardous constituents.
The objective of this assessment is to determine if there is sufficient evidence of
a release to require the permittee to undertake additional investigation. If the RFA
indicates that further investigation is required, the next step is the RCRA Facility
Investigation (RFI), during which the permittee assesses the identified releases by
characterizing their nature, extent, and rate of migration. The goal of the RFI is
to provide sufficient data to determine if remedial action is required. Next, the permit-
tee conducts a Corrective Measure Study (CMS), during which appropriate remedial
measures are identified. The Region then selects the appropriate remedial measures

which the permittee must implement. See 55 Fed. Reg. 30,801--30,802 (July 27, 1990);

chrome plater site because GMC is on the verge of completing reme-
dial measures “which have been demonstrated to be extremely effec-
tive.” Petition for Review at 13. Specifically, GMC contends that,
with the approval of State and local officials,

[it] has identified the source of the contamination
and its extent, has implemented measures, which
have been entirely successful, to retract the contami-
nation plume, has excavated the most severely im-
pacted soil, has designed a flushing system to deal
with remaining contaminated soil and is ready to
begin operation of that flushing system.

Petition for Review at 12. Accordingly, GMC argues, additional re-
quirements imposed under HSWA are unnecessary.

Although we agree with GMC that the Region should consider
GMC’s current remediation efforts and that the permit’s corrective
action requirements should reflect sufficient site-specificity to avoid
imposing unnecessary requirements on the permittee,!° we conclude
that under the facts of this case review is not warranted. In its
Response to Comments on the draft permit, the Region stated that
“[w]here the U.S. EPA determines that the data generated by pre-
vious investigations are adequate to characterize the release, these
data may be summarized, and used to satisfy the requirements [of]
the Statement of Work. The HSWA permit may then be modified
to avoid unnecessary waste of time and resources.” Response to Com-
ments at 14. Further, in its response to the petition for review,
the Region stated that “GMC may summarize and submit data which
are proposed to meet some of the informational requirements of the
[Scope of Work] * * *.”11 Region’s Response at 21. Thus, if GMC
can establish that the work it has performed to date is sufficient
to satisfy some or all of the permit’s corrective action requirements,
the Region must take full advantage of this work to avoid unneces-
sary duplication and to minimize GMC’s paperwork obligations. See

28 at 5-6 (Adm’r, July 26, 1990); In re Hoechst Celanese Corp.,

No. 89-8 at 7 (August 5, 1991).

11We also note that the Region has agreed to review a document submitted
by GMC entitled Remediation Plan for the Former South Chromium Plater Site, Delco
Marine NDH, Needmore Road Facility, Dayton, Ohio, for equivalency to the Corrective
Measure Study (CMS) requirements. Region’s Response at 22.

DIVISION, ET AL.

RCRA Appeal No 87-13 at 4 (Adm’r, February 28, 1989). Given
the Region’s willingness to consider the data GMC has generated
through its prior investigations and to allow GMC to use these data
to satisfy the permit’s corrective action requirements (if the data
are adequate to characterize the release), we see no reason to grant
review. We note that if GMC’s site investigations and remedial ac-
tions to date are as extensive and successful as it alleges, GMC’s
remaining corrective action responsibilities should not be substantial.

GMC concedes that regardless of whether the chrome plater site
is a “SWMU”, EPA has the authority to impose corrective action
requirements under RCRA §3005(c)(3) (Petition for Review at 16).14
GMC nonetheless argues that the permit should be remanded because
the Region failed to make a determination that the permit’s corrective
action conditions are necessary in order to protect human health
and the environment as required by § 3005(c)(3).15 GMC is in error.
Permit Condition III.A. states, in part:

The source of the [chromium] contamination has
been identified as a temporary holding tank which
was formerly located beneath the plater. This tank
was built to contain the chrome plating solution as
the plater was emptied for maintenance. The U.S.
EPA has determined that a RCRA Facility Investiga-
tion is required for the former chrome plater site.

The facility has undertaken some remediation of the
soil and ground water as an interim measure. None-
theless, concerns for the municipal aquifer underly-
ing the facility indicate that further investigation and
corrective action are necessary to protect human
health and the environment.

(Emphasis added). As the foregoing permit provision indicates, the
Region has made a determination that the release of a hazardous

12GMC argues that the permit improperly designates the chrome plater site as
a “potential SWMU.” Petition for Review at 10. However, because the Region has
agreed that the site is not a SWMU (see Region’s Response at 11), and because
corrective action requirements have been imposed under the authority of RCRA
§3005(c)(3), we see no reason to grant review on this issue.

13RCRA §3005(c)(3) authorizes corrective action for non-SWMU areas when nec-
essary to protect human health and the environment. See In re: LCP Chemicals-
North Carolina, Inc., RCRA Appeal No. 90-4, pp. 3-4 (Adm’r, February 14, 1991);
In re: Amarada Hess Corp., RCRA Appeal No. 88-10, pp. 3, 5 (Adm’r, August 15,
1989).

constituent (chromium) potentially endangers a drinking water source
for the City of Dayton and that corrective action is necessary in
order to protect human health and the environment. Nothing in
GMC’s petition for review or in the record on appeal convinces us
that this determination warrants review.

4. Overly Broad Corrective Action Provisions

GMC argues that the North Plant permit’s Scope of Work Correc-
tive Action Plan (SOW), Permit Attachment II, improperly imposes
boilerplate corrective action requirements not tailored to site-specific
conditions at the facility. That is, even though the Region has ac-
knowledged that the only area at the facility which requires corrective
action is the former chrome plater site, the language of the SOW
indicates that it applies to the facility as a whole. Thus, according
to GMC, the Region has “illegally transformed the corrective action
program and [RCRA] §3005(c)(3) into an extensive facility-wide re-
quirement not supported by the facts in the record or by a determina-
tion of necessity at this facility.” Petition for Review at 17.

As noted above, we agree that to the extent practicable corrective
action requirements must be tailored to site-specific conditions at
the facility. See In re American Cyanamid Co., RCRA Appeal No.
89-9 at 7 (Adm'r, Aug. 5, 1991); Sandoz Pharmaceuticals, supra,
at 11; RCRA Corrective Action Plan (Interim Final) at 1 (June 1988)
(OSWER Directive 9902.3) (“Each facility has unique characteristics
and circumstances affecting it that need to be incorporated into any
requirements for corrective action.”). Nonetheless, under the cir-
cumstances of this case, we conclude that review or remand are
not warranted.

Permit Condition III.A. (Summary of RFA findings), indicates
that the only release which warrants corrective action is the former
chrome plater site:

[b]ased on data gathered for the RFA, there is evi-
dence of a release of a hazardous constituent from
the former chrome plater site * * *.

The permit does not mention any other releases nor does it indicate
that corrective action is required at any location other than the
chrome plater site. Indeed, the Region itself (in its response to the
petition for review) argues that the permit unequivocally states that
corrective action is only required at the chrome plater site. Region’s
Response at 14. We accept the Region’s representation that the per-

VOLUME 4

DIVISION, ET AL.

mit’s corrective action requirements apply only to the chrome plater
site and the Agency is hereby bound by this interpretation.1+ This
limiting construction of the permit language renders the issue moot.15
See In re W.R. Grace & Company, RCRA Appeal No. 89-28, at 4
n.6 (Adm’r, March 25, 1991).

GMC also argues that several of the specific requirements in
the SOW for the North Plant permit are unnecessary or overly broad.
Most of these arguments are individually unpersuasive and are dis-
cussed briefly below:

(1) GMC contends that much of the information required by
the SOW has already been provided in GMC’s Part B permit applica-
tion. As the Region notes, however, the SOW specifically states that
any information submitted in the Part B application may be incor-
porated by reference into any of the reports required by the SOW.
See SOW at 1; Region’s Response at 20. Any duplication of effort
will therefore be minimized;

(2) GMC contends that because “of the absence of a SWMU
determination and of the existence of prior studies on the chromium
release, no need for a RFI workplan has been shown.” Petition for
Review at 19. As noted above, however, the chrome plater site is
not designated as a SWMU in the permit. Rather, the Region has

14We note that GMC has conceded that the Region did not intend the require-
ments of the SOW to apply to the entire facility. See Petition for Review at 15.
15On September 11, 1992, GMC filed a document entitled Supplemental Authori-
ties by General Motors Corporation. GMC has called the Board’s attention to two
Agency memoranda which it contends support its argument that the Region improperly
relied on Agency guidance and ignored site-specific conditions at the facility. These
are: 1) a May 27, 1992 memorandum from Don Clay, Assistant Administrator, to
Regional Division Directors, regarding “Considerations in Ground-Water Remediation
at Superfund Sites and RCRA Facilities—Update;” and 2) a March 27, 1991 memoran-
dum from Lisa K. Friedman, Associate General Counsel, Solid Waste and Emergency
Response Division, to Regional Counsel RCRA Branch Chiefs, regarding “Use of Pro-
posed Subpart S Corrective Action Rule as Guidance Pending Promulgation of Final
Rule” (hereinafter Friedman Memo). Both documents indicate that although most of
the proposed Subpart S corrective action proposal (see 55 Fed. Reg. 30,798 et seq.
(July 27, 1990)) may be used as guidance, any specific permit requirements based
on this proposal must be justified on a case-by-case basis. Friedman Memo at 3.
Neither of these submissions affects our determination on this issue. GMC has
not presented any evidence that the Region improperly relied on the Subpart S pro-
posal in establishing these requirements nor does the record on appeal contain any
such evidence. Moreover, as noted above, the Region has agreed to consider whether
GMC’s voluntary remediation efforts are equivalent to the HSWA corrective action
requirements. Thus, any corrective action requirements will be tailored to site-specific
conditions.

VOLUME 4
344 ENVIRONMENTAL ADMINISTRATIVE DECISIONS

determined that corrective action is necessary in order to protect
public health and the environment and nothing in GMC’s petition
convinces us that this determination requires review. Moreover, as
noted above, the permit allows GMC to reference any previously
provided information;

(3) GMC objects to the requirements that it study and character-
ize soil parameters and surface waters. As the Region points out,
however, available data indicate that these media have been contami-
nated by the chromium release. The Region determined that such
studies are necessary “to ascertain the behavior of the chromium
contamination in the soil and groundwater especially in light of
GMC’s proposal to leave chromium contamination in place in the
aquifer.” Region’s Response at 21 (emphasis in original). The record
on appeal indicates that this determination was a reasonable one
and nothing in GMC’s petition convinces us otherwise;

(4) GMC contends that, because of the work it has already done,
part II of the SOW (Corrective Measure Study (CMS)), requiring
GMC to develop and review remedial alternatives, is unjustified. We
disagree. As noted above (see supra p.10), the Region has agreed
to review GMC’s voluntary remediation efforts for equivalence to
HSWA to avoid unnecessary duplication. Ultimately, it is the Region’s
responsibility to determine whether GMC’s remediation efforts are
consistent with and equivalent to the standards imposed by HSWA.
See National RCRA Corrective Action Strategy, at p.25 (OSWER
1986). Moreover, the Region has expressed reservations about GMC’s
intention to leave trivalent chromium in the subsoil under the facility
and the possibility of future mobilization of the remaining chromium.

U.S. EPA is particularly concerned with the evalua-
tion of the remedy’s effectiveness, confirmatory test-
ing of the treated soil, risk assessment for the re-
maining contamination, the proposed total chromium
levels to remain in the soil, and contingency plans
to be implemented if the residual chromium levels
exceed specified target concentrations for the project.
U.S. EPA does not feel that these issues have been
adequately addressed in GMC’s voluntary remedi-
ation.

Region’s Response at 22. Given the Region’s concern for the municipal
aquifer underlying the facility, we reject GMC’s assertion that the
permit’s CMS provisions are unjustified;

VOLUME 4
GENERAL MOTORS CORPORATION, DELCO MORAINE 345
DIVISION, ET AL.

(5) GMC contends that, upon discovery of any new releases, the
permit would require the preparation of a new RFI workplan rather
than adding the new release to an existing workplan. According to
GMC, this will be “wasteful, duplicative and will delay remediation.”
Petition for Review at 21. The language of the permit does not sup-
port this assertion. Permit Condition III.F. (Notification Require-
ments for Newly Discovered Releases at SWMUs) states that upon
discovery of any release(s), the “Regional Administrator may require
further investigation” and that “{a] plan for such investigation will
be reviewed for approval as part of the RFI workplan.” (emphasis
added). This provision does not result in the duplication and delay
alleged by GMC. As the Region states in its response, the investiga-
tion plan:

will be reviewed by U.S. EPA to determine if the
investigation can be made part of the already exist-
ing workplan, or if a new workplan is required. A
new workplan will be required if incorporation could
delay or obstruct the conduct of the already existing
workplan.

Region’s Response at 23. If, because of the nature of the new release
and the media impacted, the Region determines that a new workplan
is required, “the Permittee may reference general or specific facility
information which was previously gathered in RFIs, the Part B Per-
mit Application, the RFA and other sources.” Id. at 23-24. Moreover,
the Region has indicated that it will “evaluate the previously gath-
ered information for its equivalency to the informational needs of
the newly imposed RFI.” Id. at 24;

(6) GMC contends that the CMS provisions “require adherence
to unspecified ‘relevant’ provisions of other laws, which is not author-
ized by RCRA or any rule” and that the permit “requires compliance
with criteria, standards or guidance that are not rules.” Petition
for Review at 20-21. In addition, GMC contends that the standards
imposed for the Region’s approval of corrective measures (in Permit
Attachment II.H.) are beyond those in the permit itself and are not
justified by RCRA. Because these issues were not raised during the
public comment period, review is denied; and

(7) GMC contends that “although the only alleged problem at
the [North] plant is groundwater contamination, air must be studied.”

Petition for Review at 19. Because this issue was not raised during
the public comment period, review is denied.1&

On the following issue raised by GMC, the permit is remanded
to the Region. GMC points out that the North Plant permit’s report-
ing requirements are inconsistent. That is, while Permit section ITI.D.
requires bimonthly progress reports on the status of GMC’s corrective
action obligations, sections I.E.2. and ILE.2. of Permit Attachment
II require monthly reports. In addition, Permit Section II.D. and
section LE. of Attachment II list different items to be included in
these reports. In its response, the Region states that the permit
will be revised to require bimonthly reporting and that “the list
of items to be included in the bimonthly reports will be revised
to match the list specified in Condition III.D. of the HSWA permit.”
Region’s Response at 21. On remand, the Region must modify the
permit to reflect these changes.

5. Interim Measures Provision

GMC contends that North Plant Permit Condition III.H.17 (In-
terim Measures) is “arbitrary and unreasonable and a denial of due
process” because: (1) the Region may require interim measures with-
out a finding of “an immediate and significant threat”; (2) GMC
has no opportunity to object to the interim measures selected by

16We note that if GMC can establish that air has not been impacted by the
release and that characterization of the air surrounding the North Plant facility is
therefore unnecessary, GMC may request a permit modification, and we would urge
the Region to respond positively to such a request. See RCRA Corrective Action Plan
(Interim Final), p.1 (June 1988) (OSWER Directive 9902.3) (“[ilf there is sufficient
information on a site to preclude an air release, then it would not be necessary
to require the owner/operator or respondent to perform an air contamination character-
ization.”).
17 Permit Condition III.H. states, in part:

If during the course of any activity initiated under this Corrective

Action Schedule of Compliance, the Regional Administrator deter-

mines that a release or potential release of hazardous waste, in-

cluding hazardous constituents from a SWMU, poses a threat to

human health and the environment, the Regional Administrator

may specify interim measures. The Regional Administrator shall

determine the specific action(s) that must be taken to implement

the interim measure, including potential permit modifications and

the schedule for implementing the required measures. The Re-

gional Administrator shall modify the Corrective Action Schedule

of Compliance either according to the procedures in Section ITI.M.

of this permit or according to the permit modification procedures

under 40 CFR 270.41, to incorporate such interim measures into

the permit.

DIVISION, ET AL.

the Region; and (3) to the extent the remedial measures are not
coordinated with ongoing remediation efforts, they are improper.

The Agency places strong emphasis on the use of interim meas-
ures to initiate expedited remediation where necessary at RCRA fa-
cilities that require corrective action. In re BFGoodrich Company,
RCRA Appeal No. 89-29, at 7 (Adm’r, Dec. 19, 1990); 55 Fed. Reg.
30,838-39 (July 27, 1990). As the permit makes clear, however (see
supra n.17), no such measures may be required unless the Region
finds that they are necessary to protect human health and the envi-
ronment.18 GMC’s assertion that the permit allows the Region to
arbitrarily impose interim measures is therefore rejected.

Permit Condition III.H. states that the permit will be modified
to incorporate the interim measures selected by the Regional Admin-
istrator according to the procedures in Permit Condition III.M. (Modi-
fication of the Corrective Action Schedule of Compliance)19 or the

18See RCRA Corrective Action Interim Measures Guidance (Interim Final), at 1
(June 1988) (The implementation of interim measures must be related to human
health and the environment).

19 Permit Condition III.M. provides, in part:

If at any time the Regional Administrator determines that modi-
fication of the Corrective Action Schedule of Compliance is nec-
essary, he or she may initiate a modification to the Schedule
of Compliance according to the procedures of this section. If the
Regional Administrator initiates a modification, he or she shall:

1. Notify the Permittee in writing of the proposed modification
   and the date by which comments on the proposed modification
   must be received;

2. Publish a notice of the proposed modification in a locally distrib-
   uted newspaper, mail a notice to all persons on the facility mailing
   list * * * and place a notice in the facility’s information repository
   eee

a. If the Regional Administrator receives no written comment on
the proposed modification, the modification shall become effective
five (5) calendar days after the close of the comment period.

b. If the Regional Administrator receives written comment on the
proposed modification, the Regional Administrator shall make a
final determination concerning the modification after the end of
the comment period.

3. Notify the Permittee in writing of the final decision.

a. If no written comment was received, the Regional Administrator
shall notify individuals on the facility mailing list in writing that
the modification has become effective * * *.

b. If written comment was received, the Regional Administrator
shall provide notice of the final modification decision in a locally
distributed newspaper * * *.

VOLUME 4
348 ENVIRONMENTAL ADMINISTRATIVE DECISIONS

modification procedures of 40 C.F.R. § 270.41. GMC objects to the
abbreviated modification procedure in Permit Condition III.M. on the
grounds that it does not provide for administrative review of modifica-
tions initiated and finalized by the Regional Administrator as re-
quired by the existing regulation on modifications at 40 C.F.R.
§ 270.41. See Petition for Review at 22-29. GMC is correct in noting
that the permit’s abbreviated modification procedure represents a
change in existing regulatory requirements set forth in 40 C.F.R.
§ 270.41. Because this procedure has not been adopted by regulation,
the Region must remove Permit Condition III.M. from the permit
and revise Permit Condition III.H. to specify that Agency-initiated
modifications to incorporate interim measures must proceed according
to the existing modification procedures in 40 C.F.R. § 270.41.

Finally, GMC’s concern that interim measures will not be coordi-
nated with voluntary remediation efforts is unfounded. As noted
above, the Region has indicated that it will evaluate GMC’s ongoing
remediation efforts for equivalency to HSWA corrective action re-
quirements. Nothing in the permit or in the record on appeal indi-
cates that these remediation efforts would be ignored in determining
what (if any) interim measures would be necessary in the event
of a newly discovered release. Review is therefore denied.

6. Due Process

In its petition for review of the North Plant permit GMC objects
to certain permit provisions allowing the Regional Administrator to
revise (or require GMC to revise) certain interim submittals prepared
during the corrective action process without complying with the Agen-
cy’s permit modification rules (40 C.F.R. Parts 124 and 270) and
without an opportunity for an administrative appeal. Once approved
by the Regional Administrator these submittals then become an en-
forceable part of the permit. According to GMC, these provisions
deprive it of its constitutional right of due process.

The Board has recently granted review and scheduled oral argu-
ment on issues that bear on the scope and effect of the Agency's
authority to revise interim submittals. See In re Allied-Signal, Inc,
RCRA Appeal No. 92-1 (EAB, Nov. 3, 1992). The Order Granting
Review and Scheduling Oral Argument lists 6 issues that the parties
in Allied-Signal should address in their briefs and should be prepared
to discuss at oral argument. In light of this, we grant review on

VOLUME 4
GENERAL MOTORS CORPORATION, DELCO MORAINE 349
DIVISION, ET AL.

the due process issue with regard to the North Plant permit.2° The
parties shall file briefs addressing the following issues:

1. The Administrator ruled in In re W.R. Grace &
   Company, RCRA Appeal No. 89-28 (Adm’r, March
   25, 1991) that a Region’s revision of an interim sub-
   mission is not a modification of the permit for pur-
   poses of the formal modification rule at 40 CFR
   § 270.41. In contrast, the selection of a remedy is
   treated as a modification of the permit that is subject
   to the formal modification rule. [Permit Condition
   III K]. What is the legal or policy basis for treating
   the selection of a remedy as a permit modification,
   while not treating the Region’s revision of an interim
   submission as a permit modification? In other words,
   how does the Agency decide that some, but not all,
   new permit terms will be incorporated into the per-
   mit through means of the formal permit modification
   procedures?

2. The Grace decision requires that in the event of
   a Regional revision of an interim submission, the
   Region must provide the permittee with some sort
   of informal “hearing” procedure in order to satisfy
   the requirements of procedural due process. Would
   the following procedure satisfy the requirements of
   procedural due process: (i) the Region must give a
   reasoned explanation in writing of its revision; (ii)
   the permittee must be provided with an opportunity
   to demonstrate, through written comments, that the
   Region’s proposed revision is unnecessary; and (iii)
   the Region must consider the permittee’s comments
   and provide a written response to them?

3. If the informal hearing procedure outlined in para-
   graph 1 would not satisfy the requirements of proce-
   dural due process, what additional Agency proce-
   dures would be necessary to satisfy those require-
   ments?

20 Although the petition for review of the South Plant permit also raises a due
process issue regarding the corrective action portion of that permit, the South Plant
permit does not require GMC to perform any corrective action and GMC has failed
to identify any specific permit conditions that would arguably result in a denial of
due process. Review of this issue is therefore denied with regard to the South Plant
permit.

VOLUME 4
350 ENVIRONMENTAL ADMINISTRATIVE DECISIONS

4. If the Board determines that a particular informal
   hearing procedure is necessary to satisfy the require-
   ments of procedural due process, should the Board
   require the Region to incorporate that procedure in
   the permit?

5. Does the Grace decision, by holding that the revi-
   sion of an interim submission is not a permit modi-
   fication under 40 CFR §270.41, unlawfully deprive
   permittees of a statutory right to judicial review by
   preventing permittees from invoking Section 7006(b),
   which provides that any interested person may ob-
   tain judicial review of the Administrator’s action
   modifying the permit in the U.S. Court of Appeals?

6. If GMC is unable to obtain judicial review under
   Section 7006(b), when and under what circumstances
   could GMC obtain judicial review of a Regional revi-
   sion of an interim submission?

Briefs must be submitted by December 9, 1992.

7. Authority To Modify the Permit Under RCRA §3005(c)(3)

Permit Condition I.B. (in both the North and South Plant per-
mits) states, in part:

This permit may be modified, revoked and reissued,
or terminated for cause as specified in 40 CFR
270.41, 270.42, and 270.43. This permit may also
be reviewed and modified at any time by the U.S.
EPA, for causes specified in 40 CFR 270.41, and
as determined necessary to protect human health and
the environment, pursuant to Section 3005(c)(3) of
RCRA, 42 U.S.C. §6925(c)(3).

(Emphasis added). GMC objects to the underlined portion of the
above-quoted language. Specifically, GMC contends that the Agency
does not have unlimited authority under RCRA § 3005(c)(3) to review
and modify an existing permit. Rather, according to GMC, this au-
thority is limited by the requirements in 40 C.F.R. § 270.41.21 Petition
for Review at 30-31. We agree.

2140 C.F.R. § 270.41 lists several causes for permit modifications and states that
“[iJf cause does not exist under this section, the Director shall not modify or revoke

VOLUME 4
GENERAL MOTORS CORPORATION, DELCO MORAINE 351
DIVISION, ET AL.

As the Board has recently noted, by promulgating 40 C.F.R.
§ 270.41 (a) & (b), the Agency has restricted its ability to unilaterally
modify existing permits. In re Waste Technologies Industries, East
Liverpool, Ohio, Consolidated RCRA Appeal Nos. 92-7 et al., at
10 (July 24, 1992). Thus, “the Agency may not invoke §3005(c)(3)
to bypass these regulations, for it is axiomatic that the Agency must
follow its own regulations. Service v. Dulles, 354 U.S. 363, 372
(1957).” Id. Accordingly, the Region must delete the following lan-
guage from the second clause of the second sentence of Final Permit
Condition IB. of the North and South Plant Permits: “and as deter-
mined necessary to protect human health and the environment, pur-
suant to Section 3005(c)(3) of RCRA, 42 U.S.C. §6925(c)(3).”

This conclusion does not mean that the Region is powerless to
modify or terminate the permit should it discover that any permitted
activity endangers human health and the environment. On the con-
trary, should such a situation arise, the Region has several available
options. For example, the regulations allow the Region to initiate
a permit modification upon receiving new information (unavailable
at the time the permit was issued) that would have justified different
permit conditions at the time of issuance. 40 C.F.R. § 270.41(a)(2).

and reissue the permit, except on request of the permittee.” The following are causes
for permit modification:
(a)(1) Alterations. There are material and substantial alterations
or additions to the facility * * *.
(2) Information. The Director has received information. Permits
may be modified during their terms for this cause only if the
information was not available at the time of permit issuance * * *
and would have justified the application of different permit condi-
tions at the time of issuance.
(3) New Statutory requirements or regulations. The standards or
regulations on which the permit was based have been changed
by statute * * * or by judicial decision after the permit was is-
sued.
(4) Compliance Schedules. The Director determines that good
cause exists for modification of a compliance schedule, such as
an act of God, * * * or other events over which the permittee
has little or no control and for which there is no reasonably
available remedy.
(b) Causes for modification or revocation and reissuance. The fol-
lowing are causes to modify or, alternatively, revoke and reissue
a permit:
(1) Cause exists for termination under § 270.43, and the Director
determines that modification or revocation and reissuance is ap-
propriate.
(2) The Director has received notification * * * of a proposed
transfer of the permit.

VOLUME 4
352 ENVIRONMENTAL ADMINISTRATIVE DECISIONS

Moreover, procedures exist for modifying, revoking and reissuing,
or terminating a permit if any permitted activity endangers human
health and the environment and can only be regulated to acceptable
levels by modification or termination. 40 C.F.R. §§270.41(b)(1),
270.43(a)(3). Thus, today’s ruling only reaffirms that the Region’s
authority to review and modify existing permits under RCRA
§ 3005(c)(3) is limited by the above-cited regulations.

8. Notice of Changes in Plant Operations

GMC argues that Permit Condition I.D.10 (Reporting Planned
Changes) in both the North Plant and South Plant Permits is beyond
the scope of a HSWA permit. That condition provides:

The Permittee shall give notice to the Regional Ad-
ministrator of any planned physical alterations to
the permitted facility as soon as possible, and at
least 30 days before such alteration or addition is
commenced.

GMC argues that this provision is overly broad in that alteration
or additions to the facility may or may not be related to HSWA
requirements. Only the State of Ohio, GMC contends, has the author-
ity to administer the non-HSWA portion of the RCRA permit. GMC
states that Ohio already receives relevant notices related to plant
operations and the Region is therefore without authority to include
such a requirement in the HSWA permit.

In support of this provision, the Region relies solely on 40 C.F.R.
§270.30(l)(1) which states that “[t]he permittee shall give notice to
the director as soon as possible of any planned physical alterations
or additions to the permitted facility.” As the Board has recently
concluded, however, in a split permit situation, with the non-HSWA
portion being issued by an authorized State and the HSWA portion
being issued by the Region, it is the responsibility of the State permit-
ting authority to implement the requirements of 40 C.F.R. § 270.30.
See In the Matter of General Electric Company, RCRA Appeal No.
91-7, at 34 (EAB, November 6, 1992). Thus, if the Region wishes
to include a provision similar to the one at §270.30(l)(1), it must
rely on the corrective action rule at 40 C.F.R. § 264.101 and it must
tailor such a provision so that it would apply only to those changes
in plant operations affecting GMC’s HSWA obligations. Id. Accord-
ingly, on remand, if the Region wants to maintain this provision
in the permit, it must adopt it under the authority of, and consistent

VOLUME 4
GENERAL MOTORS CORPORATION, DELCO MORAINE 353
DIVISION, ET AL.

with the requirements of, the corrective action rule at 40 C.F.R.
§ 264.101.

9. Definition of Hazardous Waste

GMC objects to the permit’s definition of “hazardous waste.”22
Specifically, GMC contends that the definition does not conform to
the statutory definition at RCRA § 1004(5), 42 U.S.C. §6903(5).23
The only difference between the statutory definition of hazardous
waste and the permit’s definition is that, under the permit, the term
“hazardous waste” includes hazardous constituents. Although hazard-
ous constituents are not specifically mentioned in the definition at
RCRA § 1004(5), this definition is in accord with the corrective action
requirements imposed under the HSWA amendments. For example,
RCRA § 3004(u), 42 U.S.C.A. §6924(u), requires the Agency to impose
corrective action requirements for all releases of hazardous waste
or constituents from SWMUs. The legislative history of Section
3004(u) states that:

This section is not limited to hazardous waste listed
or identified under Section 3001 of the Act because
it may be impossible to determine if hazardous con-
stituents come from hazardous wastes as currently
defined by the Administrator. The term “hazardous
constituent” as used in this provision is intended
to mean those constituents listed in Appendix VIII
of the RCRA regulations.

H.R. Rep. No. 198, 98th Cong., Ist Sess. Part 1, 60-61 (1983). Thus,
Congress clearly intended to expand the universe of hazardous wastes
beyond those listed in section 3001 of RCRA by including hazardous

22 Permit Condition III.B. defines “hazardous waste” as:

a solid waste, or combination of solid wastes, which because of
quantity, concentration, or physical, chemical, or infectious charac-
teristics may cause, or significantly contribute to an increase in
mortality, or an increase in serious, irreversible, or incapacitating
reversible, illness; or pose a substantial present or potential haz-
ard to human health or the environment when improperly treated,
stored, transported, or disposed of, or otherwise managed. The
term hazardous waste includes hazardous constituent as defined
below.

“Hazardous constituent” means any constituent identified in Ap-
pendix VIII of 40 CFR Part 261, or any constituent identified
in Appendix IX of 40 CFR Part 264.
23 Although GMC raised several other arguments in its petition for review, this
was the only issue raised in its comments on the draft permit. See Comment 19.

VOLUME 4
354 ENVIRONMENTAL ADMINISTRATIVE DECISIONS

constituents. See In re Owen Electric Steel Company of South Caro-
lina, RCRA Appeal No. 89-37, at 4-6 (Adm’r, Feb. 28, 1992). The
permit’s definition is consistent with this approach.

10. Photographs

GMC argues that both the North and South Plant permits im-
properly allow the Region to photograph GMC’s facility without ade-
quate protection for the confidentiality of its trade secrets. GMC,
however, cites no specific permit condition to which it objects. We
gather, based on GMC’s comments on the draft permit, that GMC
is referring to Permit Condition I.D.8. (Inspection and Entry). This
condition, however, makes no mention of photographs. Moreover,
GMC has indicated that it agrees with EPA’s rights to inspection
and entry. GMC’s Comments on Draft Permit, Comment 7 at A-

2. Apparently, GMC is concerned that during inspections allowed
   under the permit the Region may decide to take photographs, and
   that these photos may not be treated as confidential business infor-
   mation. These concerns, without more, do not establish a link to
   a “condition” of the permit. Without such a link, there is no jurisdic-
   tional basis for the Board to examine GMC’s concern, for only
   “condition[s] of the permit decision” are reviewable on appeal to the
   Board. 40 C.F.R. § 124.19. See BFGoodrich Company, supra, at 4
   & n.6 (the intended application of a permit term is not subject to
   review under 40 C.F.R. § 124.19). GMC’s concern in this regard does
   not contest any specific permit condition, nor does it allege that
   any of the Region’s permit determinations were clearly erroneous
   or otherwise important enough to warrant review. Moreover, even
   if GMC were contesting a specific permit condition, both permits
   incorporate by reference the regulations at 40 C.F.R. Part 2, Subpart
   B, regarding the protection of confidential business information, and
   GMC has failed to convince us that these regulations would be insuf-
   ficient to protect GMC’s trade secrets. Accordingly, review is denied.

3. Split Samples

In commenting on the draft permits for both plants, GMC re-
quested that the permits allow it to split samples. Although the
Region agreed to this request, no such language was added to either
permit. In its responses, however, the Region has agreed to revise
both permits to include language guaranteeing GMC’s right to split
samples and the Region is ordered to do so on remand.

VOLUME 4
GENERAL MOTORS CORPORATION, DELCO MORAINE 355
DIVISION, ET AL.

12. Severability

GMC argues that Permit Condition I.C. (Severability).24 of both
the North and South Plant permits conflicts with the language of
40 C.F.R. § 124.16(a)(2) (Stays of Contested Permit Conditions).25 We
find no conflict between these provisions. Permit Condition I.C. mere-
ly states the general proposition that severable portions of the permit
remain in effect even if other portions of a permit are held invalid
(presumably by the Board or a reviewing court). Section 124.16(a)(2),
on the other hand, indicates that uncontested, non-severable portions
of a permit are stayed along with contested provisions if the Board
decides to grant review.

III. ISSUES UNIQUE TO SOUTH PLANT PETITION

1. Permit Term

GMC contends that the permit is internally inconsistent because
the cover letter states that the duration of the permit is 10 years
while Permit Condition I.D.3. states that the permit will expire in
5 years. GMC also states that the five year term in the permit
was inadvertent and that “[t]he permit term should be at least 10
years as permitted under 40 CFR §270.50(a).” Petition for Review
at 7. None of these arguments convinces us that review is warranted.

First, the cover letter is not part of the final permit. Rather,
it simply accompanies the final permit when it is mailed to the
permittee. It notifies the permittee that a final permit determination
has been reached and informs the permittee of the procedures for
filing an appeal. Thus, any difference between the language of the
cover letter and the permit does not create an internal inconsistency
in the permit itself. Moreover, the Region has acknowledged the
error in the cover letter and has stated that the permit’s term is
actually five years. Region’s Response at 5.

24 Permit Condition I.C. states:
The provisions of this permit are severable, and if any provision
of this permit, or if the application of any provision of this permit
to any circumstance is held invalid, the application of such provi-
sion to other circumstances and the remainder of this permit
shall not be affected thereby.

25 40 C.F.R. § 124.16(a)(2) states:
Uncontested conditions which are not severable from those con-
tested shall be stayed together with the contested conditions.
Stayed provisions * * * shall be identified by the Regional Admin-
istrator. All other provisions of the permit * * * shall remain
fully effective and enforceable.

VOLUME 4
356 ENVIRONMENTAL ADMINISTRATIVE DECISIONS

Second, the record on appeal does not support the assertion that
the five year term was inadvertent. The Fact Sheet describing the
provisions of the draft permit as well as the draft permit itself pro-
posed a 5 year term. In addition, as the Region states in its Response:

The five year term coincides with the term of the
State RCRA permit. Setting the same term for both
portions of the permit will simplify the review and
renewal process for both GMC and the regulatory
agencies, as both will be reviewed at the same time.

Region’s Response at 5.

Finally, GMC does not expressly challenge the five year term,
nor does it give any reason why such a term is improper.26 Review
is therefore denied.

2. Deletion of Permit Condition I.D.18

In its response to comments on the draft permit,27 the Region
agreed to delete permit Condition I.D.18 but has failed to do so.
The Region has acknowledged this oversight and has agreed to delete
the provision. Region’s Response at 10. Accordingly, on remand, the
Region is ordered to delete this provision.

IV. CONCLUSION

The permits for the North and South Plants are remanded and
the Region is directed to reopen the permit proceedings for the limited
purposes mentioned above.28 Appeal of the remand decision will not
be required to exhaust administrative remedies under 40 C.F.R.
§ 124.19(f\1)(iii). For the reasons set forth above, review is granted
with regard to the due process issue raised in the North Plant peti-
tion for review. Pursuant to Section 124.19(c), the Region is directed
to give public notice of this grant of review in accordance with Section

26In comment #3 on the draft permit for the South Plant, GMC requested a
permit term of 20 years. As the Region pointed out, however, 40 C.F.R. § 270.50(a)
states that “permits shall be effective for a fixed term not to exceed 10 years.” (emphasis
added). Region’s Response at 2.

27 Response to Comments at 3.

28 Although 40 C.F.R. § 124.19 contemplates that additional briefing typically will
be submitted upon a grant of a petition for review, a direct remand without additional
submissions is appropriate where, as here, it does not appear as though further
briefs on appeal would shed light on the issues addressed on remand. See, e.g., In
re: Chemical Waste Management, Inc., RCRA Appeal No. 87-12, at 5 (Adm’r, May
27, 1988).

124.10. The public notice should set out the briefing schedule noted
above and it should state that any interested person may file an
amicus brief. The notice should be sent out within two weeks of
this order to ensure that interested parties will have sufficient time
to prepare and submit amicus briefs by December 9, 1992. On the
other issues raised by GMC, review is denied for the reasons set
forth above.
