Maryland: Final Authorization of State Hazardous Waste Management 
Program Revisions

AGENCY: Environmental Protection Agency (EPA).

ACTION: Immediate final rule.

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

SUMMARY: The State of Maryland (State) has applied to EPA for Final 
authorization of changes to its hazardous waste program under the 
Resource Conservation and Recovery Act (RCRA). EPA has determined that 
these changes satisfy all requirements needed to qualify for Final 
authorization, and is authorizing the State's changes through this 
immediate final action. EPA is publishing this rule to authorize the 
changes without a prior proposal because we view this as a routine 
program change and do not expect comments that oppose it. Unless we get 
written comments which oppose this authorization during the comment 
period, the decision to authorize

[[Page 29713]]

Maryland's changes to its hazardous waste program will take effect as 
provided below. If we get comments that oppose this action, or portions 
thereof, we will publish a document in the Federal Register withdrawing 
this rule, or portions thereof, before it takes effect, and a separate 
document in the proposed rules section of this Federal Register will 
serve as a proposal to authorize the changes.

DATES: This Final authorization will become effective on July 31, 2001, 
unless EPA receives adverse written comment by July 2, 2001. If EPA 
receives such comment, it will publish a timely withdrawal of this 
immediate final rule in the Federal Register and inform the public that 
this authorization will not take effect.

ADDRESSES: Send written comments to Carol Johnson, Mailcode 3WC21, RCRA 
State Programs Branch, U.S. EPA Region III, 1650 Arch Street, 
Philadelphia, PA 19103-2029, Phone number: (215) 814-3378. We must 
receive your comments by July 2, 2001. You can view and copy Maryland's 
application from 8:30 a.m. to 4:30 p.m., Monday through Friday at the

SUPPLEMENTARY INFORMATION:

A. Why Are Revisions to State Programs Necessary?

    States which have received Final authorization from EPA under RCRA 
section 3006(b), 42 U.S.C. 6926(b), must maintain a hazardous waste 
program that is equivalent to, consistent with, and no less stringent 
than the Federal program. As the Federal program changes, States must 
change their programs and ask EPA to authorize the changes. Changes to 
State programs may be necessary when Federal or State statutory or 
regulatory authority is modified or when certain other changes occur. 
Most commonly, States must change their programs because of changes to 
EPA's regulations in 40 Code of Federal Regulations (CFR) parts 124, 
260 through 266, 268, 270, 273 and 279.

B. What Decisions Have We Made in This Rule?

    EPA concludes that Maryland's application to revise its authorized 
program meets all of the statutory and regulatory requirements 
established by RCRA. Therefore, we grant Maryland Final authorization 
to operate its hazardous waste program with the changes described in 
the authorization application. Maryland has responsibility for 
permitting treatment, storage, and disposal facilities (TSDFs) within 
its borders and for carrying out the aspects of the RCRA program 
described in its revised program application, subject to the 
limitations of the Hazardous and Solid Waste Amendments of 1984 (HSWA). 
New Federal requirements and prohibitions imposed by Federal 
regulations that EPA promulgates under the authority of HSWA take 
effect in authorized States before they are authorized for the 
requirements. Thus, EPA will implement those requirements and 
prohibitions in Maryland, including issuing permits, until the State is 
granted authorization to do so.

C. What Is the Effect of Today's Authorization Decision?

    The effect of this decision is that a facility in Maryland subject 
to RCRA will have to comply with the authorized State requirements 
instead of the equivalent Federal requirements in order to comply with 
RCRA. Maryland has enforcement responsibilities under its state 
hazardous waste program for violations of such program, but EPA retains 
authority under RCRA sections 3007, 3008, 3013, and 7003, which 
include, among others, authority to:
     Do inspections, and require monitoring, tests, analyses or 
reports;
     Enforce RCRA requirements and suspend or revoke permits; 
and
     Take enforcement actions regardless of whether the State 
has taken its own actions.
    This action does not impose additional requirements on the 
regulated community because the regulations for which Maryland is being 
authorized by today's action are already effective, and are not changed 
by today's action.

D. Why Wasn't There a Proposed Rule Before Today's Rule?

    EPA did not publish a proposal before today's rule because we view 
this as a routine program change and do not expect comments that oppose 
this approval. We are providing an opportunity for public comment now. 
In addition to this rule, in the proposed rules section of today's 
Federal Register we are publishing a separate document that proposes to 
authorize the State program changes. If EPA receives comments which 
oppose this authorization, or portion(s) thereof, that document will 
serve as a proposal to authorize such changes.

E. What Happens if EPA Receives Comments That Oppose This Action?

    If EPA receives comments that oppose this authorization, we will 
withdraw this rule by publishing a document in the Federal Register 
before the rule becomes effective. EPA will base any further decision 
on the authorization of the State's program changes on the proposal 
mentioned in the previous paragraph. We will then address all public 
comments in a later final rule. You may not have another opportunity to 
comment. If you want to comment on this authorization, you must do so 
at this time.
    If EPA receives comments that oppose only the authorization of a 
particular change to the State hazardous waste program, we may withdraw 
that part of this rule, but the authorization of the program changes 
that the comments do not oppose will become effective on the date 
specified above. The Federal Register withdrawal document will specify 
which part of the authorization will become effective, and which part 
is being withdrawn.

F. What Has Maryland Previously Been Authorized for?

    Title 7, Subtitle 2 of the Health-Environmental Article of the 
Annotated Code of Maryland, as amended through 1984, authorized the 
Department of Health and Mental Hygiene (DHMH) to ``adopt rules and 
regulations to carry out the provisions of this subtitle'' and to 
``administer and enforce this subtitle and the rules, regulations, and 
orders adopted or issued under this subtitle.'' The DHMH promulgated 
regulations to implement Subtitle 2 in Chapters 10.51.01 through 
10.51.07 of the Code of Maryland Regulations. The State received Final 
authorization from EPA to implement its base hazardous waste program 
effective February 11, 1985 (50 FR 3511; January 25, 1985).
    The statutory provisions concerning hazardous waste management were 
shifted without renumbering to the newly created Environment Article of 
the Annotated Code of Maryland in 1987. At that time, the 
responsibilities for adopting rules and regulations, and for 
administering and enforcing Subtitle 2, were transferred to the newly 
created Maryland Department of the Environment (MDE). Since Maryland's 
base program authorization, the State

[[Page 29714]]

has made numerous changes to its regulations. Most notably, in 1989 the 
regulations were recodified in Chapters 26.13.01 through 26.13.10 of 
the Code of Maryland Regulations with conforming changes to internal 
references and some renumbering of provisions in Chapters 26.13.02 and 
26.13.05. MDE's latest regulatory revisions took effect on October 16, 
2000.

G. What Changes Are We Authorizing With Today's Action?

    On December 21, 2000, Maryland submitted a final, complete program 
revision application seeking authorization of its changes in accordance 
with 40 CFR 271.21. EPA Region III worked closely with the State to 
develop the authorization package. Therefore, EPA's comments relative 
to the State's legal authority to carry out aspects of the Federal 
program for which the State is seeking authorization, the scope and 
coverage of activities regulated, and the State's procedures, including 
the criteria for permit reviews, public participation and enforcement 
capabilities, were addressed before the submission of the final 
application by the State. Maryland also solicited public comments on 
its proposed regulations before they were adopted.
    Maryland's program revision application includes statutory and 
regulatory changes to the State's authorized hazardous waste program, 
including the adoption of interim status regulations, the adoption of 
changes to the Federal hazardous waste regulations addressed by 
selected Revision Checklists listed in the following table, and the 
adoption of State-initiated changes. The State's statutory references 
are to the Environment Article, Title 7, Subtitle 2 of the Annotated 
Code of Maryland (1996 Repl. Vol., 1999 Cumul. Supp.). The regulatory 
references are to Title 26, Subtitle 13 of the Code of Maryland 
Regulations (COMAR), Chapters 01 through 07, and Chapter 10, as amended 
effective October 16, 2000.
    We now make an immediate final decision, subject to receipt of 
written comments that oppose this action, that Maryland's hazardous 
waste program revision satisfies all of the requirements necessary to 
qualify for Final authorization. Therefore, we grant Maryland Final 
authorization for the following program changes:

2. State-Initiated Changes

    Maryland's program revision application includes State-initiated 
changes that are not directly related to any of the Revision Checklists 
in the previous table. All the State-initiated changes are either (1) 
related to the adoption of a provision at 26.13.01.05 that makes 
conforming and clarification changes to the State's adoption by 
reference of Federal regulations and statutes, (2) related to general 
renumbering with conforming changes that do not impact equivalency, or 
(3) related to the extension of the maximum duration of a permit from 
three to five years. The State-initiated changes include the following 
provisions of the State's program: COMAR 26.13.01.05B, 26.13.01.05C, 
26.13.07.02E, 26.13.07.02-1 through 26.13.07.02-10, and 26.13.07.06A.

H. Where Are the Revised State Rules Different From the Federal 
Rules?

    EPA considers several Maryland requirements to be more stringent 
than the Federal requirements. These requirements are part of the 
State's authorized program and are Federally enforceable. The specific 
more stringent provisions are noted in the above table and in 
Maryland's authorization application and include, but are not limited 
to, the following:
    1. Unlike the Federal program, Maryland does not have reduced 
requirements for generators who generate 100 kg to 1000 kg of hazardous 
waste in a calendar month. In addition, the State has more stringent 
requirements for generators using tanks for accumulation.
    2. Maryland subjects transporters of recyclable materials utilized 
for precious metal recovery to full regulation as transporters under 
COMAR 26.13.04.
    3. Maryland does not allow the financial test or corporate 
guarantee in 40 CFR 264.143(f), 264.145(f), 265.143(e), or 265.145(e) 
to be used to establish financial assurance for closure or post-closure 
care.
    4. Maryland does not allow materials contaminated with a waste 
identified solely on the basis of ignitability to be used for road 
treatment or dust suppression unlike the Federal program.
    5. Maryland has a complete ban on the disposal of bulk or non-
containerized waste containing free liquids in landfills.
    6. Maryland prohibits underground injection of hazardous waste at 
COMAR 26.13.05.19 and 26.13.06.27.
    7. Maryland provides for two classifications of permit 
modifications rather than the three categories in the Federal 
regulations. For similar levels of permit modifications, the State 
requires a higher degree of public involvement and agency approval.
    A number of Maryland's regulations are not being authorized by 
today's actions. A full description of the State's provisions that MDE 
is not being authorized for can be found in the State's application. 
Some of these provisions include, but are not limited to, the 
following:
    1. Maryland has adopted rules addressing the wood preserving 
listings (F032, F034, and F035) at COMAR 26.13.02.04A(9), .16A, .16C, 
.23, and .24, as well as the requirements for drip pads at COMAR 
26.13.01.03B(16-1); 26.13.03.05E(1)(b)(iii) & .05E(1)(l); 
26.13.05.10A(5) & .17-1 through 17-4; 26.13.06.26; and 26.13.07.02-11. 
However, Maryland is not seeking authorization at this time for these 
regulations.
    2. Maryland has adopted rules addressing the dioxin listings (F020, 
F021, F022, F023, F026, F027, and F028) at COMAR 26.13.02.05E(6)(a), 
.15E(1), .16A, .19, .23, and .24, as well as special requirements for 
facilities handling these wastes at COMAR 26.13.05.09H(5), .11K, .12J, 
.13N, .14P & .16F(1)(b); COMAR 26.13.06.01A(6), .23C & .24B(1); and 
COMAR 26.13.07.02-4B(17), .02-5B(10), .02-7B(7) & .02-8B(8). Again, 
Maryland is not seeking authorization at this time for these 
regulations.
    Maryland's regulations contain several requirements that go beyond 
the scope of the Federal program, and thus are not part of the program 
being authorized by today's action. EPA cannot enforce these 
requirements which are broader in scope, although compliance with these 
provisions is required by Maryland law. Such provisions include, but 
are not limited to the following:
    1. Maryland has chosen to specifically list as hazardous waste 
materials that are not listed in the Federal regulations. These wastes 
are identified with the following waste codes: K067, K068, K122, K133, 
K134, K991, K992, K993, K994, K995, K996, K997, K998, K999, M001, MT01, 
MX01, MD01, and MD02.
    2. Maryland does not have an analog to the Federal provision at 40 
CFR 261.6(a)(3)(vii) which exempts from regulation coke and coal tar 
waste (K087) from the iron and steel industries when it is recycled.
    3. The State operates a certification program for hazardous waste 
haulers, drivers domiciled in Maryland, and vehicles.

I. Who Handles Permits After the Authorization Takes Effect?

    After authorization, Maryland will issue permits covering all the 
provisions for which it is authorized and will administer the permits 
it issues. EPA will continue to administer any RCRA hazardous waste 
permits or portions of permits which we issued prior to the effective 
date of this authorization until the timing and process for effective 
transfer to the State are mutually agreed upon. Until such time as 
formal transfer of EPA permit responsibility to the State occurs and 
EPA terminates its permit, EPA and the State agree to coordinate the 
administration of permits in order to maintain consistency. We will not 
issue any more new permits or new portions of permits for the 
provisions listed in the Chart above after the effective date of this 
authorization. EPA will continue to implement and issue permits for 
HSWA requirements for which Maryland is not yet authorized.

J. How Does Today's Action Affect Indian Country (18 U.S.C. 115) in 
Maryland?

    Maryland is not seeking authority to operate the program on Indian 
lands, since there are no Federally-recognized Indian Lands in the 
State.

K. What Is Codification and Is EPA Codifying Maryland's Hazardous 
Waste Program as Authorized in This Rule?

    Codification is the process of placing the State's statutes and 
regulations that comprise the State's authorized hazardous waste 
program into the Code of Federal Regulations. We do this by referencing 
the authorized State rules in 40 CFR part 272. We reserve the amendment 
of 40 CFR 272, subpart V, for this authorization of Maryland's program 
changes until a later date.

L. Administrative Requirements

    The Office of Management and Budget has exempted this action from 
the requirements of Executive Order 12866 (58 FR 51735, October 4, 
1993), and, therefore, this action is not subject to review by OMB. 
This action authorizes state requirements for the purpose of RCRA 3006 
and imposes no additional requirements beyond those imposed by state 
law. Accordingly, I certify that this action will not have a 
significant economic impact on a substantial number of small entities 
under the Regulatory Flexibility Act (5 U.S.C. 601 et seq.). Because 
this action authorizes pre-existing requirements under state law and 
does not impose any additional enforceable duty beyond that required by 
state law, it does not contain any unfunded mandate or significantly or 
uniquely affect small governments, as described in the Unfunded 
Mandates Reform Act of 1995 (Public Law 104-4). For the same reason, 
this action also does not significantly or uniquely affect the 
communities of tribal governments, as specified by Executive Order 
13084 (63 FR 27655, May 10, 1998). This action will not 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, as 
specified in Executive Order 13132 (64 FR 43255, August 10, 1999), 
because it merely authorizes state requirements as part of the State 
RCRA hazardous waste program without altering the relationship or the 
distribution of power and responsibilities established by RCRA. This 
action also is not subject to Executive Order 13045 (62 FR 19885, April 
23, 1997), because it is not economically significant and it does not 
make decisions based on environmental health or safety risks.
    Under RCRA 3006(b), EPA grants a State's application for 
authorization as long as the State meets the criteria required by RCRA. 
It would thus be inconsistent with applicable law for EPA, when it 
reviews a State authorization application, to require the use of any 
particular voluntary consensus standard in place of another standard 
that otherwise satisfies the requirements of RCRA. Thus, the 
requirements of section 12(d) of the National Technology Transfer and 
Advancement Act of 1995 (15 U.S.C. 272 note) do not apply. As required 
by section 3 of Executive Order 12988 (61 F.R. 4729, February 7, 1996), 
in issuing this rule, EPA has taken the necessary steps to eliminate 
drafting errors and ambiguity, minimize potential litigation, and 
provide a clear legal standard for affected conduct. EPA has complied 
with Executive Order 12630 (53 F.R. 8859, March 15, 1988) by examining 
the takings implications of the rule in accordance with the Attorney 
General's ``Supplemental Guidelines for the Evaluation of Risk and 
Avoidance of Unanticipated Takings'' issued under the executive order. 
This rule does not impose an information collection burden under the 
provisions of the Paperwork Reduction Act of 1995 (44 U.S.C. 3501 et 
seq.).
    The Congressional Review Act, 5 U.S.C. 801 et seq., as added by the 
Small Business Regulatory Enforcement Fairness Act of 1996, generally 
provides that before a rule may take effect, the agency promulgating 
the rule must submit a rule report, which includes a copy of the rule, 
to each House of the Congress and to the Comptroller General of the 
United States. EPA will submit a report containing this document and 
other required information to the U.S. Senate, the U.S. House of 
Representatives, and the Comptroller General of the United States prior 
to publication in the Federal Register. A major rule cannot take effect 
until 60 days after it is published in the Federal Register. This 
action is not a ``major rule'' as defined by 5 U.S.C. 804(2). This 
action will be effective July 31, 2001.
