Hazardous Waste Management System; Identification and Listing of 
Hazardous Waste; Proposed Exclusion

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule and request for comment.

-----------------------------------------------------------------------

SUMMARY: EPA is proposing to grant a petition submitted by General 
Motors Corporation-Arlington Truck Assembly Plant (GM-Arlington) to 
exclude (or delist) a wastewater treatment plant (WWTP) sludge 
generated by GM-Arlington in Arlington, TX. from the lists of hazardous 
wastes.
    EPA used the Delisting Risk Assessment Software (DRAS) in the 
evaluation of the impact of the petitioned waste on human health and 
the environment.

[[Page 41359]]

    EPA bases its proposed decision to grant the petition on an 
evaluation of waste-specific information provided by the petitioner. 
This proposed decision, if finalized, would exclude the petitioned 
waste from the requirements of hazardous waste regulations under the 
Resource Conservation and Recovery Act (RCRA).
    If finalized, EPA would conclude that GM-Arlington's petitioned 
waste is non-hazardous with respect to the original listing criteria. 
EPA would also conclude that GM-Arlington's process minimizes short-
term and long-term threats from the petitioned waste to human health 
and the environment.

DATES: EPA will accept comments until September 2, 2005. EPA will stamp 
comments received after the close of the comment period as late. These 
late comments may not be considered in formulating a final decision. 
Your requests for a hearing must reach EPA by August 3, 2005. The 
request must contain the information prescribed in 40 CFR 260.20(d).

ADDRESSES: Please send three copies of your comments. You should send 
two copies to Ben Banipal, Chief of the Corrective Action and Waste 
Minimization Section, Multimedia Planning and Permitting Division (6PD-
C), Environmental Protection Agency, 1445 Ross Avenue, Dallas, Texas

I. Overview Information

A. What Action Is EPA Proposing?

    EPA is proposing:
    (1) To grant GM-Arlington's delisting petition to have its WWTP 
sludge excluded, or delisted, from the definition of a hazardous waste; 
and be subject to certain verification and monitoring conditions.
    (2) To use the Delisting Risk Assessment Software (DRAS) to 
evaluate the potential impact of the petitioned waste on human health 
and the environment. The Agency used this model to predict the 
concentration of hazardous constituents released from the petitioned 
waste, once it is disposed.

B. Why Is EPA Proposing To Approve This Delisting?

    GM-Arlington's petition requests an exclusion from the F019 waste 
listing pursuant to Sec. Sec.  260.20 and 260.22. GM-Arlington does not 
believe that the petitioned waste meets the criteria for which EPA 
listed it. GM-Arlington also believes no additional constituents or 
factors could cause the waste to be hazardous. EPA's review of this 
petition included consideration of the original listing criteria and 
the additional factors required by the Hazardous and Solid Waste 
Amendments of 1984 (HSWA). See section 3001(f) of RCRA, 42 U.S.C. 
6921(f), and 40 CFR 260.22 (d)(1)-(4) (hereinafter all sectional 
references are to 40 CFR unless otherwise indicated). In making the 
initial delisting determination, EPA evaluated the petitioned waste 
against the listing criteria and factors cited in Sec. Sec.  
261.11(a)(2) and (a)(3). Based on this review, EPA agrees with the 
petitioner that the waste is non-hazardous with respect to the original 
listing criteria. If EPA had found, based on this review, that the 
waste remained hazardous based on the factors for which the waste was 
originally listed, EPA would have proposed to deny the petition. EPA 
evaluated the waste with respect to other factors or criteria to assess 
whether there is a reasonable basis to believe that such additional 
factors could cause the waste to be hazardous. EPA considered whether 
the waste is acutely toxic, the concentration of the constituents in 
the waste, their tendency to migrate and to bioaccumulate, their 
persistence in the environment once released from the waste, plausible 
and specific types of management of the petitioned waste, the 
quantities of waste generated, and waste variability. EPA believes that 
the petitioned waste does not meet the listing criteria and thus should 
not be a listed waste. EPA's proposed decision to delist waste from GM-
Arlington is based on the information submitted in support of this 
rule, including descriptions of the wastes and analytical data from the 
Arlington, TX facility.

C. How Will GM-Arlington Manage the Waste if It Is Delisted?

    If the sludge is delisted, the WWTP sludge from GM-Arlington will 
be disposed of at the following RCRA Subtitle D lined landfill with a 
leachate collection system: Waste Management, East Oak Landfill, 3201 
Mostley Road, Oklahoma City, OK 73141, EPA ID: OKD149934705. Since GM-
Arlington intends to send its waste to Oklahoma and the Oklahoma 
Department of Environmental Quality (ODEQ) in the State is authorized 
for the delisting program, GM-Arlington must obtain delisting 
authorization from ODEQ before it can manage the waste as non-hazardous 
in Oklahoma.

D. When Would the Proposed Delisting Exclusion Be Finalized?

    RCRA section 3001(f) specifically requires EPA to provide a notice 
and an

[[Page 41360]]

opportunity for comment before granting or denying a final exclusion. 
Thus, EPA will not grant the exclusion until it addresses all timely 
public comments (including those at public hearings, if any) on this 
proposal.
    RCRA section 3010(b)(1) at 42 USCA 6930(b)(1), allows rules to 
become effective in less than six months when the regulated facility 
does not need the six-month period to come into compliance. That is the 
case here, because this rule, if finalized, would reduce the existing 
requirements for persons generating hazardous wastes.
    EPA believes that this exclusion should be effective immediately 
upon final publication because a six-month deadline is not necessary to 
achieve the purpose of section 3010(b), and a later effective date 
would impose unnecessary hardship and expense on this petitioner. These 
reasons also provide good cause for making this rule effective 
immediately, upon final publication, under the Administrative Procedure 
Act, 5 U.S.C. 553(d).

E. How Would This Action Affect the States?

    Because EPA is issuing this exclusion under the Federal RCRA 
delisting program, only States subject to Federal RCRA delisting 
provisions would be affected. This would exclude States which have 
received authorization from EPA to make their own delisting decisions.
    EPA allows States to impose their own non-RCRA regulatory 
requirements that are more stringent than EPA's, under section 3009 of 
RCRA, 42 U.S.C. 6929. These more stringent requirements may include a 
provision that prohibits a federally issued exclusion from taking 
effect in the State. Because a dual system (that is, both Federal 
(RCRA) and State (non-RCRA) programs) may regulate a petitioner's 
waste, EPA urges petitioners to contact the State regulatory authority 
to establish the status of their wastes under the State law.
    EPA has also authorized some States (for example, Louisiana, 
Oklahoma, Georgia, Illinois) to administer a RCRA delisting program in 
place of the Federal program, that is, to make State delisting 
decisions. Therefore, this exclusion does not apply in those authorized 
States unless that State makes the rule part of its authorized program. 
If GM-Arlington transports the petitioned waste to or manages the waste 
in any State with delisting authorization, GM-Arlington must obtain 
delisting authorization from that State before it can manage the waste 
as non-hazardous in the State.

II. Background

A. What Is the History of the Delisting Program?

    EPA published an amended list of hazardous wastes from non-specific 
and specific sources on January 16, 1981, as part of its final and 
interim final regulations implementing section 3001 of RCRA. EPA has 
amended this list several times and published it in Sec. Sec.  261.31 
and 261.32.
    EPA lists these wastes as hazardous because: (1) The wastes 
typically and frequently exhibit one or more of the characteristics of 
hazardous wastes identified in subpart C of part 261 (that is, 
ignitability, corrosivity, reactivity, and toxicity), (2) the wastes 
meet the criteria for listing contained in Sec.  261.11(a)(2) or 
(a)(3), or (3) the wastes are mixed with or derived from the treatment, 
storage or disposal of such characteristic and listed wastes and which 
therefore become hazardous under Sec.  261.3(a)(2)(iv) or (c)(2)(i), 
known as the ``mixture'' or ``derived-from'' rules, respectively.
    Individual waste streams may vary, however, depending on raw 
materials, industrial processes, and other factors. Thus, while a waste 
described in these regulations or resulting from the operation of the 
mixture or derived-from rules generally is hazardous, a specific waste 
from an individual facility may not be hazardous.
    For this reason, Sec. Sec.  260.20 and 260.22 provide an exclusion 
procedure, called delisting, which allows persons to prove that EPA 
should not regulate a specific waste from a particular generating 
facility as a hazardous waste.

B. What Is a Delisting Petition, and What Does It Require of a 
Petitioner?

    A delisting petition is a request from a facility to EPA or an 
authorized State to exclude wastes from the list of hazardous wastes. 
The facility petitions EPA because it does not consider the wastes 
hazardous under RCRA regulations.
    In a delisting petition, the petitioner must show that waste 
generated at a particular facility does not meet any of the criteria 
for which the waste was listed. The criteria for which EPA lists a 
waste are in part 261 and further explained in the background documents 
for the listed waste.
    In addition, under Sec.  260.22, a petitioner must prove that the 
waste does not exhibit any of the hazardous waste characteristics (that 
is, ignitability, reactivity, corrosivity, and toxicity) and present 
sufficient information for EPA to decide whether factors other than 
those for which the waste was listed warrant retaining it as a 
hazardous waste. (See part 261 and the listing background documents for 
F019 waste.)
    Generators remain obligated under RCRA to confirm whether their 
waste remains non-hazardous based on the hazardous waste 
characteristics even if EPA has delisted the waste.

C. What Factors Must EPA Consider in Deciding Whether To Grant a 
Delisting Petition?

    Besides considering the criteria in Sec.  260.22(a) and section 
3001(f) of RCRA, 42 U.S.C. 6921(f), and in the background documents for 
the listed wastes, EPA must consider any factors (including additional 
constituents) other than those for which EPA listed the waste, if a 
reasonable basis exists that these additional factors could cause the 
waste to be hazardous.
    EPA must also consider as hazardous waste mixtures containing 
listed hazardous wastes and wastes derived from treating, storing, or 
disposing of listed hazardous waste. See Sec.  261.3(a)(2)(iii and iv) 
and (c)(2)(i), called the ``mixture'' and ``derived-from'' rules, 
respectively. These wastes are also eligible for exclusion and remain 
hazardous wastes until excluded. See 66 FR 27266 (May 16, 2001).

III. EPA's Evaluation of the Waste Information and Data

A. What Waste Did GM-Arlington Petition EPA To Felist?

    On September 14, 2004, GM-Arlington petitioned EPA to exclude from 
the lists of hazardous wastes contained in Sec.  261.31, WWTP sludge 
(F019) generated from its facility located in Arlington, Texas. The 
waste falls under the classification of listed waste pursuant to Sec.  
261.31. Specifically, in its petition, GM-Arlington requested that EPA 
grant a standard exclusion for 3,000 cubic yards per year of the WWTP 
sludge.

B. Who Is GM-Arlington and What Process Does It Use To Generate the 
Petitioned Waste?

    The GM-Arlington is a Truck Assembly Plant. The Plant currently 
coats vehicle bodies containing at least one aluminum part with zinc 
phosphate. The zinc phosphate system at the Arlington Truck Assembly 
Plant consists of a nine-stage system designed to facilitate chemical 
cleaning of the product to ensure tight, uniform, defect-free phosphate 
coatings. The zinc phosphate coating is the foundation of the entire 
paint system that provides

[[Page 41361]]

paint adhesion and prevents under-film corrosion when the paint film is 
broken. Subsequent stages are intended to rinse and recover any 
deposited paint prior to oven baking. Overflows and rinse water from 
the coating process are discharged to the waste water treatment plant. 
In the waste water treatment process, the sludge listed as F019 from 
the thickeners and clarifiers is dewatered in one of several types of 
filter presses.
    Acrylamide was a major compound of concern for other nationwide GM 
plant's petitions, but the waste analysis indicates no presence of 
acrylamide in the waste of GM-Arlington. The analytical data show that 
it is not a characteristic waste and contains little to no detectable 
concentrations of organic constituents.

C. How Did GM-Arlington Sample and Analyze the Data in This Petition?

    To support its petition, GM-Arlington submitted:
    (1) Historical information on waste generation and management 
practices;
    (2) background information and Memorandum of Understanding for the 
Michigan Environmental Council of States project;
    (3) analytical results from six samples for total concentrations of 
constituents of concern (COCs);
    (4) analytical results from six samples for Toxicity Characteristic 
Leaching Procedure (TCLP) extract values; and
    (5) multiple pH testing for the petitioned waste.

D. What Were the Results of GM-Arlington's Analyses?

    EPA believes that the descriptions of the GM-Arlington analytical 
characterization provide a reasonable basis to grant GM-Arlington's 
petition for an exclusion of the WWTP sludge. EPA believes the data 
submitted in support of the petition show the WWTP sludge is non-
hazardous. Analytical data for the WWTP sludge samples were used in the 
DRAS to develop delisting levels. The data summaries for COCs are 
presented in Table I. EPA has reviewed the sampling procedures used by 
GM-Arlington and has determined that it satisfies EPA criteria for 
collecting representative samples of the variations in constituent 
concentrations in the WWTP sludge. In addition, the data submitted in 
support of the petition show that constituents in GM-Arlington's waste 
are presently below health-based levels used in the delisting decision-
making. EPA believes that GM-Arlington has successfully demonstrated 
that the WWTP sludge is non-hazardous.

Notes:
1. These levels represent the highest constituent concentration found in any one sample and do not necessarily
  represent the specific level found in one sample.
2. The delisting levels are from the DRAS analyses except the chemicals with a parenthesis which are the TCLP
  regulatory levels.

E. How Did EPA Evaluate the Risk of Delisting the Waste?

    For this delisting determination, EPA used such information 
gathered to identify plausible exposure routes (i.e., groundwater, 
surface water, air) for hazardous constituents present in the 
petitioned waste. EPA determined that disposal in a landfill is the 
most reasonable, worst-case disposal scenario for GM-Arlington's 
petitioned waste. EPA applied the Delisting Risk Assessment Software 
(DRAS) described in 65 FR 58015 (September 27, 2000) and 65 FR 75637 
(December 4, 2000), to predict the maximum allowable concentrations of 
hazardous constituents that may be released from the petitioned waste 
after disposal and determined the potential impact of the disposal of 
GM-Arlington's petitioned waste on human health and the environment. A 
copy of this software can be found on the World Wide Web at http://www.epa.gov/earth1r6/6pd/rcra_c/pd-o/dras.htm. In assessing potential 
risks to groundwater, EPA used the maximum waste volumes and the 
maximum reported extract concentrations as inputs to the DRAS program 
to estimate the constituent concentrations in the groundwater at a 
hypothetical receptor well down gradient from the disposal site. Using 
the risk level (carcinogenic risk of 10-\5\ and non-cancer 
hazard index of 1.0), the DRAS program can back-calculate the 
acceptable receptor well concentrations (referred to as compliance-
point concentrations) using standard risk assessment algorithms and EPA 
health-based numbers. Using the maximum compliance-point concentrations 
and EPA's Composite Model for Leachate Migration with Transformation 
Products (EPACMTP) fate and transport modeling factors, the DRAS 
further back-calculates the maximum permissible waste constituent 
concentrations not expected to exceed the compliance-point 
concentrations in groundwater.
    EPA believes that the EPACMTP fate and transport model represents a 
reasonable worst-case scenario for possible groundwater contamination 
resulting from disposal of the petitioned waste in a landfill, and that 
a reasonable worst-case scenario is appropriate when evaluating whether 
a waste should be relieved of the protective management constraints of 
RCRA Subtitle C. The use of some reasonable worst-case scenarios 
resulted in conservative values for the compliance-point concentrations 
and ensures that the waste, once removed from hazardous waste 
regulation, will not pose a significant threat to human health or the 
environment.
    The DRAS also uses the maximum estimated waste volumes and the 
maximum reported total concentrations to predict possible risks 
associated with releases of waste constituents through surface pathways 
(e.g., volatilization from the landfill). As in the above groundwater 
analyses, the DRAS uses the risk level, the health-based data and 
standard risk assessment and exposure algorithms to predict maximum 
compliance-point concentrations of waste constituents at a hypothetical 
point of exposure. Using fate and transport equations, the DRAS uses 
the maximum compliance-point concentrations and back-calculates the 
maximum allowable waste constituent concentrations (or ``delisting 
levels'').
    In most cases, because a delisted waste is no longer subject to 
hazardous waste control, EPA is generally unable to predict, and does 
not presently control, how a petitioner will manage a waste after 
delisting. Therefore, EPA currently believes that it is inappropriate 
to consider extensive site-specific factors when applying the fate and 
transport model. EPA does control the type of unit where the waste is

[[Page 41363]]

disposed. The waste must be disposed in the type of unit the fate and 
transport model evaluates.
    The DRAS results which calculate the maximum allowable 
concentration of chemical constituents in the waste are presented in 
Table I. Based on the comparison of the DRAS and TCLP Analyses results 
found in Table I, the petitioned waste should be delisted because no 
constituents of concern tested are likely to be present or formed as 
reaction products or by-products in GM-Arlington waste.

F. What Did EPA Conclude About GM-Arlington's Waste Analysis?

    EPA concluded, after reviewing GM-Arlington's processes that no 
other hazardous constituents of concern, other than those for which 
tested, are likely to be present or formed as reaction products or by-
products in the waste. In addition, on the basis of explanations and 
analytical data provided by GM-Arlington, pursuant to Sec.  260.22, EPA 
concludes that the petitioned waste does not exhibit any of the 
characteristics of ignitability, corrosivity, reactivity or toxicity. 
See Sec. Sec.  261.21, 261.22 and 261.23, respectively.

G. What Other Factors Did EPA Consider In Its Evaluation?

    During the evaluation of GM-Arlington's petition, EPA also 
considered the potential impact of the petitioned waste via non-
groundwater routes (i.e., air emission and surface runoff). With regard 
to airborne dispersion in particular, EPA believes that exposure to 
airborne contaminants from GM-Arlington's petitioned waste is unlikely. 
Therefore, no appreciable air releases are likely from GM-Arlington's 
waste under any likely disposal conditions. EPA evaluated the potential 
hazards resulting from the unlikely scenario of airborne exposure to 
hazardous constituents released from GM-Arlington's waste in an open 
landfill. The results of this worst-case analysis indicated that there 
is no substantial present or potential hazard to human health and the 
environment from airborne exposure to constituents from GM-Arlington's 
WWTP sludge.

H. What Is EPA's Evaluation of This Delisting Petition?

    The descriptions of GM-Arlington's hazardous waste process and 
analytical characterization provide a reasonable basis for EPA to grant 
the exclusion. The data submitted in support of the petition show that 
constituents in the waste are below the leachable concentrations (see 
Table I). EPA believes that GM-Arlington's waste, F019 from zinc 
phosphate coating process will not impose any threat to human health 
and the environment.
    Thus, EPA believes GM-Arlington should be granted an exclusion for 
the WWTP sludge. EPA believes the data submitted in support of the 
petition show GM-Arlington's WWTP sludge is non-hazardous. The data 
submitted in support of the petition show that constituents in GM-
Arlington's waste are presently below the compliance point 
concentrations used in the delisting decision and would not pose a 
substantial hazard to the environment. EPA believes that GM-Arlington 
has successfully demonstrated that the WWTP sludge is non-hazardous.
    EPA therefore, proposes to grant an exclusion to GM-Arlington in 
Arlington, Texas, for the WWTP sludge described in its petition. EPA's 
decision to exclude this waste is based on descriptions of the 
treatment activities associated with the petitioned waste and 
characterization of the WWTP sludge.
    If EPA finalizes the proposed rule, EPA will no longer regulate the 
petitioned waste under parts 262 through 268 and the permitting 
standards of part 270.

IV. Next Steps

A. With What Conditions Must the Petitioner Comply?

    The petitioner, GM-Arlington, must comply with the requirements in 
40 CFR part 261, appendix IX, table 1. The text below gives the 
rationale and details of those requirements.
(1) Delisting Levels
    This paragraph provides the levels of constituents for which GM-
Arlington must test the WWTP sludge, below which these wastes would be 
considered non-hazardous.
    EPA selected the set of inorganic and organic constituents 
specified in paragraph (1) of 40 CFR part 261, appendix IX, table 1, 
(the exclusion language) based on information in the petition. EPA 
compiled the inorganic and organic constituents list from the 
composition of the waste, descriptions of GM-Arlington's treatment 
process, previous test data provided for the waste, and the respective 
health-based levels used in delisting decision-making. These delisting 
levels correspond to the allowable levels measured in the TCLP 
concentrations.
(2) Waste Holding and Handling
    The purpose of this paragraph is to ensure that GM-Arlington 
manages and disposes of any WWTP sludge that contains hazardous levels 
of inorganic and organic constituents according to subtitle C of RCRA. 
Managing the WWTP sludge as a hazardous waste until initial 
verification testing is performed will protect against improper 
handling of hazardous material. If EPA determines that the data 
collected under this paragraph do not support the data provided for in 
the petition, the exclusion will not cover the petitioned waste. The 
exclusion is effective upon publication in the Federal Register but the 
disposal as non-hazardous cannot begin until the verification sampling 
is completed.
(3) Verification Testing Requirements
    GM-Arlington must complete a rigorous verification testing program 
on the WWTP sludge to assure that the sludge does not exceed the 
maximum levels specified in paragraph (1) of the exclusion language. 
This verification program operates on two levels. The first part of the 
verification testing program consists of testing the WWTP sludge for 
specified indicator parameters as per paragraph (1) of the exclusion 
language.
    If EPA determines that the data collected under this paragraph do 
not support the data provided for the petition, the exclusion will not 
cover the generated wastes. If the data from the initial verification 
testing program demonstrate that the leachate meets the delisting 
levels, GM-Arlington may request quarterly testing. EPA will notify GM-
Arlington, in writing, if and when it may replace the testing 
conditions in paragraph (3)(A) with the testing conditions in (3)(B) of 
the exclusion language.
    The second part of the verification testing program is the 
quarterly testing of representative samples of WWTP sludge for all 
constituents specified in paragraph (1) of the exclusion language. EPA 
believes that the concentrations of the constituents of concern in the 
WWTP sludge may vary over time. Consequently this program will ensure 
that the sludge is evaluated in terms of variation in constituent 
concentrations in the waste over time.
    The proposed subsequent testing would verify that GM-Arlington 
operates a treatment facility where the constituent concentrations of 
the WWTP sludge do not exhibit unacceptable temporal and spatial levels 
of toxic constituents. EPA is proposing to require GM-Arlington to 
analyze representative samples of the WWTP sludge quarterly during the 
first year of waste generation. GM-Arlington would begin quarterly 
sampling 60 days after

[[Page 41364]]

the final exclusion as described in paragraph (3)(B) of the exclusion 
language.
    EPA, per paragraph (3)(C) of the exclusion language, is proposing 
to end the subsequent testing conditions after the first year, if GM-
Arlington has demonstrated that the waste consistently meets the 
delisting levels. To confirm that the characteristics of the waste do 
not change significantly over time, GM-Arlington must continue to 
analyze a representative sample of the waste on an annual basis. Annual 
testing requires analyzing the full list of components in paragraph (1) 
of the exclusion language. If operating conditions change as described 
in paragraph (4) of the exclusion language, GM-Arlington must reinstate 
all testing in paragraph (1) of the exclusion language.
    GM-Arlington must prove through a new demonstration that their 
waste meets the conditions of the exclusion. If the annual testing of 
the waste does not meet the delisting requirements in paragraph (1), 
GM-Arlington must notify EPA according to the requirements in paragraph 
(6) of the exclusion language. The facility must provide sampling 
results that support the rationale that the delisting exclusion should 
not be withdrawn.
(4) Changes in Operating Conditions
    Paragraph (4) of the exclusion language would allow GM-Arlington 
the flexibility of modifying its processes (for example, changes in 
equipment or change in operating conditions) to improve its treatment 
process. However, GM-Arlington must prove the effectiveness of the 
modified process and request approval from EPA. GM-Arlington must 
manage wastes generated during the new process demonstration as 
hazardous waste until it has obtained written approval and paragraph 
(3) of the exclusion language is satisfied.
(5) Data Submittals
    To provide appropriate documentation that GM-Arlington's WWTP 
sludge is meeting the delisting levels, GM-Arlington must compile, 
summarize, and keep delisting records on-site for a minimum of five 
years. It should keep all analytical data obtained through paragraph 
(3) of the exclusion language including quality control information for 
five years. Paragraph (5) of the exclusion language requires that GM-
Arlington furnish these data upon request for inspection by any 
employee or representative of EPA or the State of Texas.
    If the proposed exclusion is made final, it will apply only to 
3,000 cubic yards per year of wastewater treatment sludge generated at 
the GM-Arlington after successful verification testing.
    EPA would require GM-Arlington to file a new delisting petition 
under any of the following circumstances:
    (a) If it significantly alters the manufacturing process treatment 
system except as described in paragraph (4) of the exclusion language;
    (b) If it uses any new manufacturing or production process(es), or 
significantly changes from the current process(es) described in their 
petition; or
    (c) If it makes any changes that could affect the composition or 
type of waste generated.
    GM-Arlington must manage waste volumes greater than 3,000 cubic 
yards per year of WWTP sludge as hazardous until EPA grants a new 
exclusion.
    When this exclusion becomes final, GM-Arlington's management of the 
wastes covered by this petition would be relieved from subtitle C 
jurisdiction and the WWTP sludge from GM-Arlington will be disposed in 
the RCRA subtile D landfill of Waste Management East Oak Landfill in 
Oklahoma City, OK, with EPA ID: OKD149934705.
(6) Reopener
    The purpose of paragraph (6) of the exclusion language is to 
require GM-Arlington to disclose new or different information related 
to a condition at the facility or disposal of the waste, if it is 
pertinent to the delisting. GM-Arlington must also use this procedure 
if the waste sample in the annual testing fails to meet the levels 
found in paragraph (1). This provision will allow EPA to reevaluate the 
exclusion if a source provides new or additional information to EPA. 
EPA will evaluate the information on which EPA based the decision to 
see if it is still correct, or if circumstances have changed so that 
the information is no longer correct or would cause EPA to deny the 
petition, if presented.
    This provision expressly requires GM-Arlington to report differing 
site conditions or assumptions used in the petition in addition to 
failure to meet the annual testing conditions within 10 days of 
discovery. If EPA discovers such information itself or from a third 
party, it can act on it as appropriate. The language being proposed is 
similar to those provisions found in RCRA regulations governing no-
migration petitions at Sec.  268.6.
    EPA believes that it has the authority under RCRA and the 
Administrative Procedures Act (APA), 5 U.S.C. 551 (1978) et seq., to 
reopen a delisting decision. EPA may reopen a delisting decision when 
it receives new information that calls into question the assumptions 
underlying the delisting.
    EPA believes a clear statement of its authority in delistings is 
merited in light of EPA's experience. See Reynolds Metals Company at 62 
FR 37694 and 62 FR 63458 where the delisted waste leached at greater 
concentrations in the environment than the concentrations predicted 
when conducting the TCLP, thus leading EPA to repeal the delisting. If 
an immediate threat to human health and the environment presents 
itself, EPA will continue to address these situations on a case by case 
basis. Where necessary, EPA will make a good cause finding to justify 
emergency rulemaking. See APA Sec.  553 (b).
(7) Notification Requirements
    In order to adequately track wastes that have been delisted, EPA is 
requiring that GM-Arlington provide a one-time notification to any 
state regulatory agency through which or to which the delisted waste is 
being carried. GM-Arlington must provide this notification 60 days 
before commencing this activity.

B. What Happens if GM-Arlington Violates the Terms and Conditions?

    If GM-Arlington violates the terms and conditions established in 
the exclusion, EPA will start procedures to withdraw the exclusion. 
Where there is an immediate threat to human health and the environment, 
EPA will evaluate the need for enforcement activities on a case-by-case 
basis. EPA expects GM-Arlington to conduct the appropriate waste 
analysis and comply with the criteria explained above in paragraph (1) 
of the exclusion.

B. How May I Review the Docket or Obtain Copies of the Proposed 
Exclusion?

    You may review the RCRA regulatory docket for this proposed rule at 
the Environmental Protection Agency Region 6, 1445 Ross Avenue, Dallas, 
Texas 75202. It is available for viewing in EPA Freedom of Information 
Act Review Room from 9 a.m. to 4 p.m., Monday through Friday, excluding 
Federal holidays. Call (214) 665-6444 for appointments. The public may

pages, and at fifteen cents per page for additional copies.

VI. Regulatory Impact

    Under Executive Order 12866, EPA must conduct an ``assessment of 
the potential costs and benefits'' for all ``significant'' regulatory 
actions.
    The proposal to grant an exclusion is not significant, since its 
effect, if promulgated, would be to reduce the overall costs and 
economic impact of EPA's hazardous waste management regulations. This 
reduction would be achieved by excluding waste generated at a specific 
facility from EPA's lists of hazardous wastes, thus enabling a facility 
to manage its waste as nonhazardous.
    Because there is no additional impact from this proposed rule, this 
proposal would not be a significant regulation, and no cost/benefit 
assessment is required. The Office of Management and Budget (OMB) has 
also exempted this rule from the requirement for OMB review under 
section (6) of Executive Order 12866.

VII. Regulatory Flexibility Act

    Under the Regulatory Flexibility Act, 5 U.S.C. 601-612, whenever an 
agency is required to publish a general notice of rulemaking for any 
proposed or final rule, it must prepare and make available for public 
comment a regulatory flexibility analysis which describes the impact of 
the rule on small entities (that is, small businesses, small 
organizations, and small governmental jurisdictions). No regulatory 
flexibility analysis is required, however, if the Administrator or 
delegated representative certifies that the rule will not have any 
impact on a small entities.
    This rule, if promulgated, will not have an adverse economic impact 
on small entities since its effect would be to reduce the overall costs 
of EPA's hazardous waste regulations and would be limited to one 
facility. Accordingly, EPA hereby certifies that this proposed 
regulation, if promulgated, will not have a significant economic impact 
on a substantial number of small entities. This regulation, therefore, 
does not require a regulatory flexibility analysis.

VIII. Paperwork Reduction Act

    Information collection and record-keeping requirements associated 
with this proposed rule have been approved by the Office of Management 
and Budget (OMB) under the provisions of the Paperwork Reduction Act of 
1980 (44 U.S.C. 3501 et seq.) and have been assigned OMB Control Number 
2050-0053.

IX. Unfunded Mandates Reform Act

    Under section 202 of the Unfunded Mandates Reform Act of 1995 
(UMRA), 2 U.S.C. 501 et seq., EPA generally must prepare a written 
statement for rules with Federal mandates that may result in estimated 
costs to State, local, and tribal governments in the aggregate, or to 
the private sector, of $100 million or more in any one year.
    When such a statement is required for EPA rules, under section 205 
of the UMRA EPA must identify and consider alternatives, including the 
least costly, most cost-effective, or least burdensome alternative that 
achieves the objectives of the rule. EPA must select that alternative, 
unless the Administrator explains in the final rule why it was not 
selected or it is inconsistent with law.
    Before EPA establishes regulatory requirements that may 
significantly or uniquely affect small governments, including tribal 
governments, it must develop under section 203 of the UMRA a small 
government agency plan. The plan must provide for notifying potentially 
affected small governments, giving them meaningful and timely input in 
the development of EPA's regulatory proposals with significant Federal 
intergovernmental mandates, and informing, educating, and advising them 
on compliance with the regulatory requirements.
    The UMRA generally defines a Federal mandate for regulatory 
purposes as one that imposes an enforceable duty upon State, local, or 
tribal governments or the private sector.
    EPA finds that this delisting decision is deregulatory in nature 
and does not impose any enforceable duty on any State, local, or tribal 
governments or the private sector. In addition, the proposed delisting 
decision does not establish any regulatory requirements for small 
governments and so does not require a small government agency plan 
under UMRA section 203.

X. Executive Order 13045

    The Executive Order 13045 is entitled ``Protection of Children from 
Environmental Health Risks and Safety Risks'' (62 FR 19885, April 23, 
1997). This order applies to any rule that EPA determines: (1) Is 
economically significant as defined under Executive Order 12866, and 
(2) the environmental health or safety risk addressed by the rule has a 
disproportionate effect on children. If the regulatory action meets 
both criteria, EPA must evaluate the environmental health or safety 
effects of the planned rule on children, and explain why the planned 
regulation is preferable to other potentially effective and reasonably 
feasible alternatives considered by EPA. This proposed rule is not 
subject to Executive Order 13045 because this is not an economically 
significant regulatory action as defined by Executive Order 12866.

XI. Executive Order 13084

    Because this action does not involve any requirements that affect 
Indian Tribes, the requirements of section 3(b) of Executive Order 
13084 do not apply.
    Under Executive Order 13084, EPA may not issue a regulation that is 
not required by statute, that significantly affects or uniquely affects 
the communities of Indian tribal governments, and that imposes 
substantial direct compliance costs on those communities, unless the 
Federal government provides the funds necessary to pay the direct 
compliance costs incurred by the tribal governments.
    If the mandate is unfunded, EPA must provide to the Office 
Management and Budget, in a separately identified section of the 
preamble to the rule, a description of the extent of EPA's prior 
consultation with representatives of affected tribal governments, a 
summary of the nature of their concerns, and a statement supporting the 
need to issue the regulation.
    In addition, Executive Order 13084 requires EPA to develop an 
effective process permitting elected and other representatives of 
Indian tribal governments to have ``meaningful and timely input'' in 
the development of regulatory policies on matters that significantly or 
uniquely affect their communities of Indian tribal governments. This 
action does not

[[Page 41366]]

involve or impose any requirements that affect Indian Tribes. 
Accordingly, the requirements of section 3(b) of Executive Order 13084 
do not apply to this rule.

XII. National Technology Transfer and Advancement Act

    Under section 12(d) of the National Technology Transfer and 
Advancement Act, 15 U.S.C. 3701, et seq., EPA is directed to use 
voluntary consensus standards in its regulatory activities unless to do 
so would be inconsistent with applicable law or otherwise impractical. 
Voluntary consensus standards are technical standards (e.g., materials 
specifications, test methods, sampling procedures, business practices, 
etc.) developed or adopted by voluntary consensus standard bodies. 
Where available and potentially applicable voluntary consensus 
standards are not used by EPA, the Act requires that EPA to provide 
Congress, through the OMB, an explanation of the reasons for not using 
such standards.
    This rule does not establish any new technical standards and thus, 
EPA has no need to consider the use of voluntary consensus standards in 
developing this proposed rule.

XIII. Executive Order 13132 Federalism

    Executive Order 13132, entitled ``Federalism'' (64 FR 43255, August 
10, 1999) requires EPA to develop an accountable process to ensure 
``meaningful and timely input by State and local officials in the 
development of regulatory policies that have federalism implications.'' 
``Policies that have federalism implications'' is defined in the 
Executive Order to include regulations that have ``substantial direct 
effects on the States, on the relationship between the national 
government and the States, or on the distribution of power and 
responsibilities among the various levels of government.''
    Under section 6 of Executive Order 13132, EPA may not issue a 
regulation that has federalism implications, that impose substantial 
direct compliance costs, and that is not required by statute, unless 
the Federal Government provides the funds necessary to pay the direct 
compliance costs incurred by State and local governments, or EPA 
consults with State and local officials early in the process of 
developing the proposed regulation. EPA also may not issue a regulation 
that has federalism implications and that preempts State law unless EPA 
consults with State and local officials early in the process of 
developing the proposed regulation.
    This action does not have federalism implication. It will not have 
a substantial direct effect on States, on the relationship between the 
national government and the States, or on the distribution of power and 
responsibilities among the various levels of government, as specified 
in Executive Order 13132, because it affects only one facility.

                                              (2) Waste Management:
                                              (A) GM-Arlington must manage as hazardous all WWTP sludge it
                                               generates, until it has completed initial verification testing
                                               described in paragraph (3)(A) and (B), as appropriate, and valid
                                               analyses show that paragraph (1) is satisfied.
                                              (B) Levels of constituents measured in the samples of the WWTP
                                               sludge that do not exceed the levels set forth in paragraph (1)
                                               are non-hazardous. GM-Arlington can manage and dispose of the non-
                                               hazardous WWTP sludge according to all applicable solid waste
                                               regulations.

                                              (C) If constituent levels in a sample exceed any of the Delisting
                                               Levels set in paragraph (1), GM-Arlington can collect one
                                               additional sample and perform expedited analyses to verify if the
                                               constituent exceeds the delisting level.
                                              If this sample confirms the exceedance, GM-Arlington must, from
                                               that point forward, treat the waste as hazardous until it is
                                               demonstrated that the waste again meets the levels in paragraph
                                               (1).GM-Arlington must manage and dispose of the waste generated
                                               under Subtitle C of RCRA from the time that it becomes aware of
                                               any exceedance.
                                              (D) Upon completion of the Verification Testing described in
                                               paragraph (3)(A) and (B), as appropriate, and the transmittal of
                                               the results to EPA, and if the testing results meet the
                                               requirements of paragraph (1), GM-Arlington may proceed to manage
                                               its WWTP sludge as non-hazardous waste. If subsequent
                                               Verification Testing indicates an exceedance of the Delisting
                                               Levels in paragraph (1), GM-Arlington must manage the WWTP sludge
                                               as a hazardous waste until two consecutive quarterly testing
                                               samples show levels below the Delisting Levels in paragraph (I).
                                              (3) Verification Testing Requirements: GM-Arlington must perform
                                               sample collection and analyses, including quality control
                                               procedures, using appropriate methods. As applicable to the
                                               method-defined parameters of concern, analyses requiring the use
                                               of SW-846 methods incorporated by reference in 40 CFR 260.11 must
                                               be used without substitution. As applicable, the SW-846 methods
                                               might include Methods 0010, 0011, 0020, 0023A, 0030, 0031,0040,
                                               0050, 0051, 0060, 0061, 1010A, 1020B, 1110A, 1310B, 1311, 1312,
                                               1320, 1330A, 9010C, 9012B, 9040C, 9045D, 9060A, 9070A (uses EPA
                                               Method 1664, Rev. A), 9071B, and 9095B. Methods must meet
                                               Performance Based Measurement System Criteria in which the Data
                                               Quality Objectives are to demonstrate that representative samples
                                               of GM-Arlington's F019 sludge meet the delisting levels in
                                               paragraph (1). If EPA judges the process to be effective under
                                               the operating conditions used during the initial verification
                                               testing, GM-Arlington may replace the testing required in
                                               paragraph (3)(A) with the testing required in paragraph (3)(B).
                                               GM-Arlington must continue to test as specified in paragraph
                                               (3)(A) until and unless notified by EPA in writing that testing
                                               in paragraph (3)(A) may be replaced by paragraph (3)(B).
                                              (A) Initial Verification Testing: After EPA grants the final
                                               exclusion, GM-Arlington must do the following:
                                              (i) Within 60 days of this exclusions becoming final, collect
                                               eight samples, before disposal, of the WWTP sludge.
                                              (ii) The samples are to be analyzed and compared against the
                                               Delisting Levels in paragraph (1)
                                              (iii) Within sixty (60) days after this exclusion becomes final,
                                               GM-Arlington will report initial verification analytical test
                                               data for the WWTP sludge, including analytical quality control
                                               information for the first thirty (30) days of operation after
                                               this exclusion becomes final. If levels of constituents measured
                                               in the samples of the WWTP sludge that do not exceed the levels
                                               set forth in paragraph (1) are also non-hazardous in two
                                               consecutive quarters after the first thirty (30) days of
                                               operation after this exclusion becomes effective, GM-Arlington
                                               can manage and dispose of the WWTP sludge according to all
                                               applicable solid waste regulations.
                                              (B) Subsequent Verification Testing: Following written
                                               notification by EPA, GM-Arlington may substitute the testing
                                               conditions in paragraph (3)(B) for paragraph (3)(A). GM-Arlington
                                               must continue to monitor operating conditions, and analyze two
                                               representative samples of the wastewater treatment sludge for
                                               each quarter of operation during the first year of waste
                                               generation. The samples must represent the waste generated during
                                               the quarter. After the first year of analytical sampling
                                               verification sampling can be performed on a single annual sample
                                               of the wastewater treatment sludge. The results are to be
                                               compared to the Delisting Levels in paragraph (1).
                                              (C) Termination of Testing:
                                              (i) After the first year of quarterly testing, if the Delisting
                                               Levels in paragraph (1) are met, GM-Arlington may then request
                                               that EPA not require quarterly testing.
                                              (ii) Following cancellation of the quarterly testing, GM-Arlington
                                               must continue to test a representative sample for all
                                               constituents listed in paragraph (1) annually.
                                              (4) Changes in Operating Conditions: If GM-Arlington significantly
                                               changes the process described in its petition or starts any
                                               processes that generate(s) the waste that may or could
                                               significantly affect the composition or type of waste generated
                                               as established under paragraph (1) (by illustration, but not
                                               limitation, changes in equipment or operating conditions of the
                                               treatment process), it must notify EPA in writing; it may no
                                               longer handle the wastes generated from the new process as non-
                                               hazardous until the wastes meet the Delisting Levels set in
                                               paragraph (1) and it has received written approval to do so from
                                               EPA.
                                              (5) Data Submittals: GM-Arlington must submit the information
                                               described below. If GM-Arlington fails to submit the required
                                               data within the specified time or maintain the required records
                                               on-site for the specified time, EPA, at its discretion, will
                                               consider this sufficient basis to reopen the exclusion as
                                               described in paragraph (6). GM-Arlington must:
                                              (A) Submit the data obtained through paragraph (3) to the Section
                                               Chief, Corrective Action and Waste Minimization Section, EPA
                                               Region 6, 1445 Ross Avenue, Dallas, Texas 75202-2733, Mail Code
                                               (6PD-C) within the time specified.
                                              (B) Compile records of operating conditions and analytical data
                                               from paragraph (3), summarized, and maintained on-site for a
                                               minimum of five years.
                                              (C) Furnish these records and data when EPA or the state of Texas
                                               requests them for inspection.
                                              (D) Send along with all data a signed copy of the following
                                               certification statement, to attest to the truth and accuracy of
                                               the data submitted:
                                              Under civil and criminal penalty of law for the making or
                                               submission of false or fraudulent statements or representations
                                               (pursuant to the applicable provisions of the Federal Code, which
                                               include, but may not be limited to, 18 U.S.C. 1001 and 42 U.S.C.
                                               6928), I certify that the information contained in or

                                              As to the (those) identified section(s) of this document for which
                                               I cannot personally verify its (their) truth and accuracy, I
                                               certify as the company official having supervisory responsibility
                                               for the persons who, acting under my direct instructions, made
                                               the verification that this information is true, accurate and
                                               complete.
                                              If any of this information is determined by EPA in its sole
                                               discretion to be false, inaccurate or incomplete, and upon
                                               conveyance of this fact to the company, I recognize and agree
                                               that this exclusion of waste will be void as if it never had
                                               effect or to the extent directed by EPA and that the company will
                                               be liable for any actions taken in contravention of the company's
                                               RCRA and CERCLA obligations premised upon the company's reliance
                                               on the void exclusion.
                                              (6) Re-opener:
                                              (A) If, anytime after disposal of the delisted waste, GM-Arlington
                                               possesses or is otherwise made aware of any environmental data
                                               (including but not limited to leachate data or groundwater
                                               monitoring data) or any other data relevant to the delisted waste
                                               indicating that any constituent identified for the delisting
                                               verification testing is at level higher than the delisting level
                                               allowed by the Division Director in granting the petition, then
                                               the facility must report the data, in writing, to the Division
                                               Director within 10 days of first possessing or being made aware
                                               of that data.
                                              (B) If the annual testing of the waste does not meet the delisting
                                               requirements in paragraph (1), GM-Arlington must report the data,
                                               in writing, to the Division Director within 10 days of first
                                               possessing or being made aware of that data.
                                              (C) If GM-Arlington fails to submit the information described in
                                               paragraphs (5),(6)(A) or (6)(B) or if any other information is
                                               received from any source, the Division Director will make a
                                               preliminary determination as to whether the reported information
                                               requires EPA action to protect human health and/or the
                                               environment. Further action may include suspending, or revoking
                                               the exclusion, or other appropriate response necessary to protect
                                               human health and the environment.
                                              (D) If the Division Director determines that the reported
                                               information does require action, the Division Director will
                                               notify the facility in writing of the actions the Division
                                               Director believes are necessary to protect human health and the
                                               environment. The notice shall include a statement of the proposed
                                               action and a statement providing the facility with an opportunity
                                               to present information as to why the proposed action by EPA is
                                               not necessary. The facility shall have 10 days from the date of
                                               the Division Director's notice to present such information.
                                              (E) Following the receipt of information from the facility
                                               described in paragraph(6)(D) or if no information is presented
                                               under paragraph(6)(D), the Division Director will issue a final
                                               written determination describing EPA's actions that are necessary
                                               to protect human health and/or the environment. Any required
                                               action described in the Division Director's determination shall
                                               become effective immediately, unless the Division Director
                                               provides otherwise.
                                              (7) Notification Requirements: GM-Arlington must do the following
                                               before transporting the delisted waste. Failure to provide this
                                               notification will result in a violation of the delisting petition
                                               and a possible revocation of the decision.
                                              (A) Provide a one-time written notification to any state
                                               regulatory agency to which or through which it will transport the
                                               delisted waste described above for disposal, 60 days before
                                               beginning such activities.
                                              (B) Submit another one-time written notification, if it ships the
                                               delisted waste into a different disposal facility.
                                              (C) Failure to provide this notification will result in a
                                               violation of the delisting variance and a possible revocation of
                                               the decision.
