Wyoming; Final Determination of Partial Program Adequacy of the
State's Municipal Solid Waste Permit Program
AGENCY: Environmental Protection Agency (Region VIII).
ACTION: Notice of final determination of partial program adequacy of
Wyoming's application.
-----------------------------------------------------------------------
SUMMARY: Section 4005(c)(1)(B) of the Resource Conservation and
Recovery Act (RCRA), as amended by the Hazardous and Solid Waste
Amendments (HSWA) of 1984, requires States to develop and implement
permit programs to ensure that municipal solid waste landfills (MSWLFs)
which may receive hazardous household waste or conditionally exempt
small quantity generator waste will comply with the revised Federal
MSWLF Criteria (40 CFR part 258). Section 4005(c)(1)(C) of RCRA
requires the Environmental Protection Agency (EPA) to determine whether
States have adequate ``permit'' [[Page 19252]] programs for MSWLFs, but
does not mandate issuance of a rule for such determinations. EPA has
drafted and is in the process of proposing the State/Tribal
Implementation Rule (STIR) that will allow both States and Tribes to
apply for and receive approval of a partial permit program. The Agency
intends to approve adequate State/Tribal MSWLF permit programs as
applications are submitted. Thus, these approvals are not dependent on
final promulgation of the STIR. Prior to promulgation of the STIR,
adequacy determinations will be made based on the statutory authorities
and requirements. In addition, States/Tribes may use the draft STIR as
an aid in interpreting these requirements. The Agency believes that
early approvals have an important benefit. Approved State/Tribal permit
programs provide interaction between the State/Tribe and the owner/
operator regarding site-specific permit conditions. Only those owners/
operators located in States/Tribes with approved permit programs can
use the site-specific flexibility provided by part 258 to the extent
the State/Tribal permit program allows such flexibility. EPA notes that
regardless of the approval status of a State/Tribe and the permit
status of any facility, the Federal Criteria will apply to all
permitted and unpermitted MSWLFs.
The State of Wyoming applied for a partial determination of
adequacy under section 4005 of RCRA. EPA reviewed Wyoming's MSWLF
application and made a tentative determination for those portions of
the State's MSWLF permit program that are adequate to assure compliance
with the revised MSWLF Criteria. After reviewing all comments received,
EPA today is granting final approval to Wyoming's partial program. All
but one element of the Federal Criteria are included in this approval.
EFFECTIVE DATE: The determination of adequacy for Wyoming shall be
effective on April 19, 1995.

SUPPLEMENTARY INFORMATION:
A. Background
On October 9, 1991, EPA promulgated revised Criteria for MSWLFs (40
CFR part 258). Subtitle D of RCRA, as amended by the Hazardous and
Solid Waste Amendments of 1984 (HSWA), requires States to develop
permitting programs to ensure that MSWLFs comply with the Federal
Criteria. Subtitle D also requires that EPA determine the adequacy of
State municipal solid waste landfill permit programs to ensure that
facilities comply with the revised Federal Criteria. To fulfill this
requirement, the Agency has drafted and is in the process of proposing
the State/Tribal Implementation Rule (STIR). The rule will specify the
requirements which State/Tribal programs must satisfy to be determined
adequate.
EPA intends to propose in the STIR to allow partial approvals if:
(1) The Regional Administrator determines that the State/Tribal permit
program largely meets the requirements for ensuring compliance with
part 258; (2) changes to a limited narrow part(s) of the State/Tribal
permit program are needed to meet these requirements; and (3)
provisions not included in the partially approved portions of the
State/Tribal permit program are a clearly identifiable and separable
subset of part 258.
EPA intends to approve portions of State/Tribal MSWLF permit
programs prior to the promulgation of the STIR. EPA interprets the
requirements for States or Tribes to develop ``adequate'' programs for
permits or other forms of prior approval to impose several minimum
requirements. First, each State/Tribe must have enforceable standards
for new and existing MSWLFs that are technically comparable to EPA's
revised MSWLF criteria. Next, the State/Tribe must have the authority
to issue a permit or other notice of prior approval to all new and
existing MSWLFs in its jurisdiction. The State/Tribe also must provide
for public participation in permit issuance and enforcement as required
in section 7004(b) of RCRA. Finally, EPA believes that the State/Tribe
must show that it has sufficient compliance monitoring and enforcement
authorities to take specific action against any owner or operator that
fails to comply with an approved MSWLF program.
EPA Regions will determine whether a State/Tribe has submitted an
``adequate'' program based on the interpretation outlined above. EPA
plans to provide more specific criteria for this evaluation when it
proposes the State/Tribal Implementation Rule. EPA expects States/
Tribes to meet all of these requirements for all elements of a MSWLF
program before it gives full approval to a MSWLF program.
B. State of Wyoming
On November 6, 1992, Wyoming submitted an application for partial
program adequacy determination for the State's MSWLF permit program. On
October 8, 1993, EPA published a final determination of partial
adequacy for Wyoming's program. Further background on the final partial
program determination of adequacy appears at 58 FR 52491 (October 8,
1993).
EPA approved the following portions of the State's MSWLF permit
program:
1. Location restrictions for airports, flood plains, wetlands,
fault areas, seismic impact zones, and unstable areas (40 CFR 258.10
through 258.15).
2. Operating criteria for the exclusion of hazardous waste, cover
materials, disease vector control, explosive gases, air criteria,
access requirements, run-on/run-off control systems, surface water
requirements, liquids restrictions, and record keeping requirements (40
CFR 258.20 through 258.29).
3. Design criteria requirements (40 CFR 258.40).
4. Closure and post-closure requirements (40 CFR 258.60 through
258.61).
EPA did not approve the following portions of the State's MSWLF
permit program:
1. Wyoming will revise its regulations to incorporate the Federal
ground-water monitoring and corrective action requirements in 40 CFR
258.50, 258.51, and 258.53 through 258.58.
2. Wyoming will develop new regulations to incorporate the
financial assurance requirements in 40 CFR 258.70 through 258.72 and
258.74. Wyoming will revise its regulations to incorporate the
financial assurance requirements in 40 CFR 258.73.
On September 30, 1994, the State of Wyoming submitted a revised
application for partial program adequacy determination. EPA reviewed
Wyoming's application and tentatively determined that the following
portions of the State's Subtitle D program will ensure compliance with
the Federal Revised Criteria.
1. Ground-water monitoring and corrective action requirements (40
CFR 258.50, 258.51, and 258.53 through 258.58).
2. Financial assurance requirements (40 CFR 258.70 through 258.74).
The October 9, 1991, Final Rules for the MSWLF Criteria included an
exemption for owners and operators of certain small MSWLF units from
the design (Subpart D) and ground-water monitoring and corrective
action (Subpart E) requirements of the Criteria. See 40 CFR 258.1(f).
To qualify for the exemption, the small landfill had to accept less
than 20 tons per day, on an average annual basis, exhibit no evidence
of ground-water contamination, and serve either:
(i) A community that experiences an annual interruption of at least
three [[Page 19253]] consecutive months of surface transportation that
prevents access to a regional waste management facility, or
(ii) A community that has no practicable waste management
alternative and the landfill unit is located in an area that annually
received less than or equal to 25 inches of precipitation.
In January 1992, the Sierra Club and the Natural Resources Defense
Council (NRDC) filed a petition with the U.S. Court of Appeals,
District of Columbia Circuit, for review of the Subtitle D criteria.
The Sierra Club and NRDC suit alleged, among other things, that EPA
acted illegally when it exempted these small landfills from the ground-
water monitoring requirement. On May 7, 1993, the United States Court
of Appeals for the District of Columbia Circuit issued an opinion
pertaining to the Sierra Club and NRDC challenge to the small landfill
exemption. Sierra Club v. United States Environmental Protection
Agency, 992 F.2d 337 (DC Cir. 1993).
In effect, the Court noted that while EPA could consider the
practicable capabilities of facilities in determining the extent or
kind of ground-water monitoring that a landfill owner/operator must
conduct, EPA could not justify the complete exemption from ground-water
monitoring requirements. Thus, the Court vacated the small landfill
exemption as it pertains to ground-water monitoring, directing the
Agency to ``* * * revise its rule to require ground-water monitoring at
all landfills.''
EPA's final rule of October 1, 1993, as required by the Court,
removed the October 9, 1991, small landfill exemption whereby owners
and operators of MSWLF units that meet the qualifications outlined in
40 CFR 258.1(f) are no longer exempt from ground-water monitoring
requirements in 40 CFR 258.50 through 258.55. The final rule does,
however, provide for an extension for all of the MSWLF criteria
requirements for a period up to two years for all MSWLF units that meet
the small landfill exemption in 2581.(f) for ground-water monitoring
and corrective action as follows: October 9, 1995, for new units; and
October 9, 1995 through October 9, 1996, for existing units and lateral
expansions.
The U.S. Court of Appeals in its decision did not preclude the
possibility that the Agency could establish separate ground-water
monitoring standards for the small dry/remote landfills that take such
factors as size, location, and climate into account.
The Agency will continue to maintain an open dialogue with all
interested parties to discuss whether alternative ground-water
monitoring requirements should be established and will continue to
accept information on alternatives. At this time, the Agency is
investigating this issue and cannot be certain that practicable
alternatives for detecting ground-water contamination will exist for
MSWLF units that would qualify for the exemption under 258.1(f). The
October 9, 1993 final rule does not link the effective date of ground-
water monitoring for landfills that qualify for the small/arid and
remote exemption to promulgation of alternative ground-water monitoring
requirements.
Under Wyoming rules, the State's 71 active MSWLFs, by definition,
consist of Type I and Type II landfills. Type II landfills, which make
up the vast majority of landfills in Wyoming, fit the same definition
as those defined as small/arid and remote landfills under 258.1(f). The
State's Type I landfills are those that are not Type II landfills. Type
II landfills currently comply with State ground-water monitoring and
corrective action rules.
Since the State's Type II landfills are not required to comply with
ground-water monitoring and corrective action criteria as defined in
258.1(f) until October 9, 1996, the State is not seeking approval for
this portion of their program at this time. When EPA promulgates final
revisions to the MSWLF 258.1(f) criteria and provides enough latitude
for states to tailor these requirements for small, arid landfills, then
the State of Wyoming will need to update their rules. It is the State
of Wyoming's position that when EPA promulgates final rule revisions to
the MSWLF criteria in 258.1(f), Wyoming will revise its application for
full program approval to bring Type II landfills into compliance with
Part 258 criteria for ground-water monitoring and corrective action.
Along with the tentative determination, EPA announced the
availability of the application for public comment. EPA also
tentatively scheduled a public hearing for March 13, 1995, to be held
if a sufficient number of people expressed interest in participating.
After no one expressed interest, the Agency cancelled the public
hearing.
EPA has reviewed Wyoming's application and has determined that all
portions of the State's MSWLF permit program (with the exception of
Wyoming's Type II landfills not being required to comply with ground-
water monitoring and corrective action as defined in 258.1(f) until
October 9, 1996) will ensure compliance with the revised Federal
Criteria. In its application, Wyoming demonstrated that the State's
permit program adequately meets the location restrictions, operating
criteria, design criteria, ground-water monitoring and corrective
action requirements, closure and post-closure care requirements, and
financial assurance criteria in the revised Federal Criteria. In
addition, the State of Wyoming also demonstrated that its MSWLF permit
program contains specific provisions for public participation,
compliance monitoring, and enforcement.
In its application for adequacy determination, Wyoming has not
asserted jurisdiction over Indian Country, as defined in 18 U.S.C.
1511. Accordingly, this approval does not extend to lands within Indian
Country in Wyoming, including lands within the exterior boundaries of
the Wind River Reservation. Until EPA approves a State or Tribal MSWLF
permitting program in Wyoming for any part of Indian Country, the
requirements of 40 CFR part 258 will, after October 9, 1993,
automatically apply to that area. Thereafter, the requirements of 40
CFR part 258 will apply to all owners/operators of MSWLFs located in
any part of Indian Country that is not covered by an approved State or
Tribal MSWLF permitting program.
Section 4005(a) of RCRA provides that citizens may use the citizen
suit provisions of section 7002 of RCRA to enforce the Federal MSWLF
Criteria in 40 CFR part 258 independent of any State/Tribal enforcement
program. As EPA explained in the preamble to the final MSWLF Criteria,
EPA expects that any owner or operator complying with provisions in a
State/Tribal program approved by EPA should be considered to be in
compliance with the Federal Criteria. See 56 FR 50978, 50995 (October
9, 1991).
C. Public Comment
The EPA received no public comments on the tentative determination
of adequacy for Wyoming's MSWLF permit program.
D. Decision
Since we received no public comments, I conclude that Wyoming's
application for partial program adequacy determination meets all the
statutory and regulatory requirements established by RCRA. Accordingly,
Wyoming is granted a determination of adequacy for all portions of its
MSWLF permit program with the exception of Wyoming's Type II landfills
not being required to comply with ground-water monitoring and
correction action as [[Page 19254]] defined in 258.1(f) until October
9, 1996.
Today's action takes effect on April 19, 1995. EPA believes it has
good cause under section 553(d) of the Administrative Procedures Act, 5
U.S.C. 553(d), to put this action into effect less than thirty days
after publication in the Federal Register. All of the requirements and
obligations in the State's/Tribe's program are already in effect as a
matter of State/Tribal law. EPA's action today does not impose any new
requirements that the regulated community must begin to comply with.
Nor do these requirements become enforceable by EPA as Federal law.
Consequently, EPA finds that it does not need to give notice prior to
making its approval effective.
Compliance With Executive Order 12866
The Office of Management and Budget has exempted this notice from
the requirements of Section 6 of Executive Order 12866.
Certification Under the Regulatory Flexibility Act
Pursuant to the provisions of 5 U.S.C. 605(b), I hereby certify
that this tentative approval will not have a significant economic
impact on a substantial number of small entities. It does not impose
any new burdens on small entities. This proposed notice, therefore,
does not require a regulatory flexibility analysis.
Authority: This notice is issued under the authority of sections
2002, 4005, and 4010 of the Solid Waste Disposal Act as amended; 42
U.S.C. 6912, 6945, and 6949(a).
Dated: April 4, 1995.

Acting Regional Administrator.
