EXECUTIVE SUMMARY
This project entailed a thorough review of the State of New Mexico
Municipal Solid Waste Landfill Regulations. The regulations
reviewed were issued July 18, 1994, and are listed by the NMED
call number EIB/SWMR-4. The review analyzed the regulations and
summarized them into four distinct sections. The sections
reviewed consist of the following regulations for municipal
landfills:
1. General Site Selection and Characterization,
2. Permitting Procedures,
3. Operation/Training/Maintenance, and;
4. Closure and Post-Closure Procedures.
The analysis of these regulations did not review regulations for
any solid waste activities not related to a general municipal
landfill project. Activities not included in this review include
special requirements for infectious wastes, transporter
requirements, collection, composting, and other peripheral
procedures.

SITE SELECTION AND CHARACTERIZATION
Initial site selection and characterization is required prior to
preparation of the permit application. All information included
in these sections will be incorporated in the permit application
when submitted.
Siting Criteria
Municipal Solid Waste Landfill Siting Criteria
1. The facility size cannot exceed 500 acres.
2. The facility cannot be located in a floodplain area.
3. The facility cannot be located within 500 feet of a
designated wetlands area.
4. The facility cannot be located within 200 feet of a
watercourse.
5. The proposed bottom of the fill area cannot be closer
than 100 feet to the seasonal high water table depth.

Natural Resources and included on the Mines, Mills, and
Quarries Map).
7. The facility cannot be located within 200 feet of a
fault with a recorded displacement within the Holocene
(11,000 years) time period. This regulation can be
bypassed with a demonstration of structural integrity
with a less than 200 foot setback.
8. The facility cannot be located in an area with
archaeologically significant sites, unless in
compliance with the Cultural Properties Act and the
Prehistoric Sites Preservation Act.
9. The facility cannot be located within 1000 feet of a
public or private well pumping 100 gpm or more.
10. The facility cannot be located within 350 feet of a
public or private well that pumps less than 100 gpm.
11. The facility cannot be located in an area within the
minimum distance to airports as set forth by the
Federal Aviation Administration. Currently, this is
listed in SWMR-4-201-B6 as 5 miles.
12. The landfill cannot be located within 50 feet from the
property boundaries and 500 feet from actual structures
of permanent residences, schools, hospitals,
institutions, or churches.
13. The landfill cannot be located in an active alluvial
fan. Active is defined as those currently aggraded by
either permanent or intermittent streams.
14. The landfill cannot be located in an area where
critical habitat of endangered or threatened species is
identified by 50 CFR Part 17 or by the Handbook of
Species Endangered in New Mexico.
15. The landfill cannot be located in seismic impact zones

with a suitable determination of no significant impact
to structural integrity submitted to the Department.
Landfill Site Characterization and Preliminary Design Criteria
Several regulatory requirements must be addressed during the
initial site characterization and the preliminary design of the
facility. All of the data and information determined in these
analyses will also be required for submittal in the permit
application package. Several of the designs, including
groundwater monitoring systems, leachate collection, and liner
design and testing protocol must be "pre-approved" by the
Department. The preliminary design includes drawings, sections,
maps, geology characterization, liner design, groundwater
monitoring system design, and leachate and gas removal/collection
design.
General Site Characterization
The preliminary design requirements are as follows:
1. A schedule of proposed filling and compaction methods.
2. Types and sources of daily, intermediate, and final
cover.

properties of condensates and residues prior to
treatment or disposal must be prepared.
Groundwater Monitoring Systems Design Criteria
All solid waste facilities must design a groundwater monitoring
system which must be maintained throughout the active life of the

Department or EPA determined "point of compliance".
Down-gradient wells will be installed at the closest
possible location to the mandated point of compliance.
4. Monitoring wells will be constructed in compliance with
ASTM method 5092 to ensure the integrity of the
borehole is maintained.
5. The bore-hole shall be drilled a minimum of 4 inches
larger than the casing diameter to allow for sealant
and sand emplacement.
6. Procedures must be implemented to ensure no
contamination is introduced to the borehole.

variations.
11. If it is confined, the top of the screen will be
located at the interface between the aquifer and the
confining layer.
12. The screen shall be centralized at the top and the
bottom.
13. The annular space +/- 2 feet from the screen will be
packed with sand having medium to coarse grain and
clean. The sand must be sized so no fines will enter
the well. A tremmie pipe will be used for placement in
deeper wells.
14. The annular space 2 feet above the sand will be grouted
or sealed with bentonite or cement using a tremmie
pipe. Alternatively, bentonite seal can be placed
using pellets, 1/4 to 1/2 inch in size.

drill cuttings or clean sandy clay to within 10 feet of
the ground surface.

Department indicating the levels and the corrective
action taken.

6. Initial assessment monitoring will be performed to
determine the presence of contaminants above background
levels, and this information will be submitted to the
Department.
7. A detection monitoring program will be implemented for
parameters in Appendix A of the regulations. The
Department can delete or add compounds to the list
after review of the background concentrations and the
proposed wastes in the landfill.
8. Monitoring frequency will be at least semi-annually
during the life of the facility. The Department can
revise monitoring frequencies after the first year to
annually if a review indicates no significant problems.
9. If a constituent is detected above assessment
monitoring levels, the Department must be notified, and
an assessment monitoring program instituted. The
assessment monitoring levels are based on the
groundwater protection standard (SWMR-4-805, and
Appendix A).
10. Alternate frequency and sample quantities will be
determined by the Department if assessment monitoring
levels are exceeded.
11. If levels are consistently higher after resampling and
statistical analyses, the facility must continue the
assessment monitoring program and notify affected
landowners. Additional monitoring wells may be
required to accurately characterize the contamination.
12. In the event of continued contamination, the facility
will implement corrective action levels for the
contaminants, then implement a corrective action
investigation to determine the measures to employ,
selection of a remedy, and implementation of the plan.
(SWMR-4-807 through SWMR-4-810).
Contingency Plan
Every facility will have a contingency plan for emergencies
submitted with the application package, and placed in the
