4.0 ENVIRONMENTAL SETTING
4.1 TRANSFER STATIONS/ RECYCLING STATIONS
Since the objective is to remove open dumps from the offshore islands of San Pedro and
Caye Caulker it will be necessary to have a transfer station in Belize City where the waste
from these islands can be temporarily stored before being transported to the central
landfill site at Mile 22.
The Mile 3 Open Dump site has been identified as the likely area to have the transfer
station located as it will minimize cost and transportation needs in transferring wastes
from the islands to Belize City. The wastes will have already been baled/bagged and
ready for transportation before it leaves either San Pedro or Caye Caulker.
4.1.1 Belize City (Mile 3 and 3.5)
The Mile 3 open Dump is located about 3 miles to the west of Belize City in a
mangrove wetland area. The central part of the Dump has the coordinates UTM
16 Q 369844 and 193494 N. The site has an approximate area of 47,000 square
meters or 11.61 acres. This site is presently closed to the disposal of any solid
waste material.
In June of 2007, a secondary open dump site also became operational in Belize
City. This site, referred to as Mile 3.5, is located about half a mile west of the
previous Mile 3 site. It has an area of 4 acres. The central section of the Open
Dump has the coordinates UTM 16 Q 369705 and 11934749 N. This site is
located in a swampy area near mangroves. It is estimated that 448 cubic yards of
solid waste is transferred from the city to this site on a daily basis. The task of
collecting and transferring the wastes to the Dump site is done under the Belize
Waste Control, a private entity contracted by the Belize City Council since 1992.

Seven (7) backload compactor trucks, each with sixteen (16) cubic yards of
capacity, are utilized to perform this task on a daily basis. Belize City is divided
into two sectors, i.e. North and South Sectors with the Haulover Creek serving as
the boundary. Each sector then has specific days on which waste is collected,
Monday and Thursday on the North and Tuesday and Friday on the South
respectively.
Currently there are no practices employed at the site for the recording the volume
of solid waste being deposited at the Mile 3.5 Open Dump.
As a component of the ETEISA Report, water and leachate samples were collected
(see appendix J) from the Mile 3 and Mile 3.5 Open Dumps. The water samples
were collected from upstream and downstream while the leachate sample was
collected from within the Dump site. In-situ analysis was also conducted with the
use of a Digital Conductivity meter (Conductronic PC-18). Table 4.1 shows the
in-situ results.

The results from the upstream samples indicated that the temperature was adequate
for this type of sample and the pH was found to be neutral, also adequate for this
sample. There were no heavy metals detected from this site. In regards to
Inorganic Macro-components, the result indicates low levels of Iron, however,
Manganese was not detected. Results also indicated that there was no presence of
Coliform bacteria detected. The laboratory data also indicates that there was no
pollution from organic loading BOD. See Table 4.2 below.

From the downstream results, it was confirmed that the temperature was also
adequate at 20.9 ºC and that there was an alkaline pH. It was noted, however, that
low levels of mercury and lead were detected. The findings also indicated that the
BOD/COD ratio is 61.7/456=0.135, which is a value characteristic of
methanogenic leachates. Coliform bacteria were also present in this sample. High
levels of iron and some manganese were also detected from this sample. The high
levels of Iron could be attributed to amount of waste iron rust. See Table 4.3

When water percolates through the waste, it promotes and assists the processes of
decomposition by bacteria and Fungi. In actively decomposing waste the
temperature rises 28.3 ºC and the pH 8.25 and many metal ions which are
relatively insoluble at neutral pH can become dissolved in the developing leachate.
As can be noted from Table 4.4 below, leachate sample laboratory results, it was
detected that there was low levels of heavy metals present. Iron on the other hand,
was relatively low, being only 5.241 mg/l. The results also indicated that here was
no pollution from organic loading as BOD was not detected, however, COD was
found to 320 mg/l. No Coliform bacteria were noted in this sample. Due to the
fact that ammonia is released by the decomposition of proteins, low levels (91.2)
of this substance were noted in the sample. An average amount (3,201mg/l) of
total dissolved solids was recorded from this sample. Average amounts of chloride
and iron was also found from this sample.

4.1.2 San Pedro
The San Pedro site is located south of Ambergris Caye and is currently being used
as an open dump. The common practice to reduce waste volume at the site is open
burning. The surrounding vegetation is mainly dwarf mangroves, which is
common in areas of little flushing as nitrates and phosphates are limiting nutrients
affecting their growth.
In a straight line, the site is approximately 1.86 miles southeast from the San Pedro
Airstrip; approximately 2.7 miles north of Grand Canal; and quarter mile from the
San Pedro Lagoon to the west and from the Caribbean Sea to the east. The nearest
Marine Protected area to the site is the Holchan Marine Reserve, to the south. The
site is located on a 26 acre parcel of land. This parcel of land is privately owned
and the San Pedro Town Board has entered into a five (5) year lease agreement
between the private land owner for the use and management of the site for the
disposal of solid waste generated on Ambergris Caye. However, of the 26 acres,
only a relatively small area of about 5-6 acres is being used for the actual
depositing of waste.
4.1.3 Caye Caulker
The Caye Caulker dump site is located on the south western area of the island,
immediately west of the airstrip. The site is approximately 1.5 acres in area and is
situated in a mangrove wetland amongst several small permanently inundated
areas and adjacent to a canal that connects to the Caribbean Sea on the leeward
side of the Island.
The site is an eyesore readily visible to tourist in particular those that fly into the
island. The geology of the area is similar to that of the San Pedro dump site. The
geologic profile is primarily comprised of a thin upper layer of coarse calcareous
BELIZE SOLID WASTE MANAGEMENT PROJECT
ENVIRONMENTAL IMPACT ASSESSMENT REVISED

sand mixed with mud and peat, underlain by peat, followed once more by a layer
of fine coralline sand before reaching limestone bedrock. The soils essentially
have very little water retention capacity and would readily permit leaching of
pollutants. The dumpsite is easily accessed by stray dogs and cats and wildlife
such as raccoons. Gulls, vultures, brown jays, grackles and other bird species are
known to frequent the site.
Because of its close proximity to residences this site has always being a site of
concern associated with the proliferation of vermin and other pests. The economy
of the Island being dependent on tourism is very vulnerable to the devastating,
potential impact which an outbreak of an environmental disease such as malaria,
typhoid or cholera could have on the livelihood of its residents. The dumpsite
receives an average of 38 tons of garbage per weak, with a considerable
percentage (45%) consisting of organic waste and plastics and styrofoam (see
appendices J and K).
The open burning of some of these wastes has been identified as one of the main
sources of releases of dioxins and furans into the atmosphere. Garbage on this site
would be periodically lit to reduce its volume and sometimes fires would occur as
a result of spontaneous combustion. Residents and visitors are not only being
affected by the smoke but could also unknowingly be exposed to the insidious
effects of some of the contaminants contained in the emissions being released. The
close proximity of the site to the Pelican Marina allows for pollutants to readily
directly enter the Caribbean Sea with its subsequent potential impacts to the
surrounding marine ecosystem. An analysis of the leachate produced by the Dump
conducted by ETIESA (appendix I ) would indicate that the site is being
contaminated.
Air traffic is sometimes negatively impacted due to low visibility caused by the
smoke and air safety reduced to the abundance of birds attracted by the site. The
Owners of the adjacent Pelican Marina have complained on several occasions
BELIZE SOLID WASTE MANAGEMENT PROJECT
ENVIRONMENTAL IMPACT ASSESSMENT REVISED
December 2008 4. 9
about the release of litter and other pollutants from the dump unto their
development which caters primarily to the tourism industry. There are local
operators who provide services to villagers and businesses of transporting their
waste material to the dump site. The vehicles utilized to carry out these services
include pickup trucks and bicycles with carts.
4.2 REGIONAL SANITARY LANDFILL: MILE 22 SITE
4.2.1 PHYSICAL ENVIRONMENT
4.2.1.1 Surrounding Land Use
The proposed solid waste site is located about 4 km due north from its
existing entry point on the Western Highway. Along this route the land is
open pine orchard savannah interspersed with occasional thickets along
low lying drainage basins which intersect the route at various points. The
site is bordered by hardwood forest to the north and by mostly broken ridge
transitional forest to the east, south and west detailed in Figure 4.1. There
are no inhabited centers or farmsteads in the areas around the access road
right of way on the landfill site and the only discernable activity now
taking place near the site is selective logging. This area falls into the Belize
River Drainage Basin with surface runoff draining into the Cox and
Mucklehany lagoons which links up to form the Mussel Creek drainage
which then empties into the Belize River near Double Run. Further away
from the site there are several ongoing and proposed developments and
business enterprises. These are Big Falls Farm, Black Orchid Garden,
Ramon’s Development, Olympic Development and Jih Chan. With the
exception of Big Falls Farm all off these properties are intended for
housing development and in the case of Jih Chan this initiative is well
under way. Big Falls Farm is located about 12.5 km. to the Northwest of
the proposed landfill site. It contains 14,700 ha. of land and in the 1970s
and 80s was a major rice producing enterprise producing an abundance for

local consumption and surplus for export. There have been tentative efforts
to revive this industry on the property since a good portion of the
infrastructure remains. The farm was and still is a noted producer of beef
cattle mainly catering to the local market. Cleared land covers about 24%
of the property with broadleaf forest and wetlands covering the remainder.
This property contains Cox Lagoon which has been noted in the past as an
area rich in wildlife, especially Crocodiles and wading birds. This wetland
area, including Mucklehaney lagoon and Mussel Creek, has been identified
as a gap in the National Protected Areas System and is a key site for
securing comprehensive community coverage and an important link
between the Northern and Southern internal Biological Corridors. This area
including its soils and vegetation types is emphasized in this study because
its drainage system encompasses the site of the proposed landfill site.
To the southeast of the site there is an area which is being proposed as a
residential community. This development called Black Orchid Garden is an
initiative spearheaded by a group of expatriate Belizean Americans who
are committed to establishing a residential development which will
accommodate the resettling of members of this group back into the
country. A development plan for this property is in circulation but so far
there has been little or no development on the ground. The property has
been surveyed. The development is shown on the site plan, Figure 3.6. This
project has become dormant for the past few years and ahs yet to obtain
environmental clearance. The north boundary of this property is being
planned as a natural buffer area that would also double as a site for utility
infrastructure and recreational purposes. This portion of the property is
close to the boundary of the landfill site and if present development plans
remain unaltered, a potential conflict over land use ma y arise. The
vegetation type over most of this property is pine orchard savannah but a
BELIZE SOLID WASTE MANAGEMENT PROJECT
ENVIRONMENTAL IMPACT ASSESSMENT REVISED

sizeable portion also falls into low waterlogged marsh with scrub
vegetation.
Ramon Development is a large property that extends to both sides of the
Western Highway and extends south of the project site. This property
includes a portion of the land that the new sanitary landfill site will be
located on. The property is mostly undeveloped and includes pine orchard
savannah on both sides of the western highway and broadleaf forest along
its south boundary with the Sibun River.
Jih Chan Limited was planned to be a major residential development along
the Western Highway. The parcel contains 3,170 acres of which 1,313
acres or 40% of the total was meant for residential purposes, 266 acres for
commercial or industrial activity, 240 acres for public easements and
recreation, 505 acres for small holder agricultural activities. The remainder
of land is allocated for the provision of infrastructural services, including a
sanitary landfill. This existing development is located about 5 km SW off
the proposed sanitary landfill site. To date the full developmental plans for
this site has not been realized and only about 35 houses have been built
with no new one built in the last five years, nevertheless the potential for
a substantial residential settlement remains.
In addition to these entities, other important sites but further afield are the
Belize Zoo (12.0 km. from the site) and Tropical Education Center (10.0
km.), La Democracia and Mahogany Heights, a New Town Site with
presently 350 new homes (both 20 km from the site).
The area around the landfill site is not dedicated to any subsistence or
commercial land use. There is no human habitation within a 4 km radius of
the site and agriculture development is minimal. The existing dirt/gravel
BELIZE SOLID WASTE MANAGEMENT PROJECT
ENVIRONMENTAL IMPACT ASSESSMENT REVISED

access road is currently being used as a temporary ‘bacadeer’ for loggers
who are operating within the area. It also appears that the access road is
occasionally used as a convenient drop off depot for the illegal dumping of
garbage. Garbage has accumulated at several locations along the southerly
portion of the route off the Western Highway.
The entire stretch of the Western Highway from Belize City to its terminus
at the border is rapidly being settled. Statistics have not been compiled to
show the rate of this increase but the Belize and Cayo District through
which the highway passes through, are the two most populous districts
having 29.8% and 22.9% of the nation’s population respectively. If present
development plans for the stretch of the Western Highway near the landfill
site materialize as planned, this area could become one of the fastest
population growth areas in the country. With the presence of Mahogany
Heights and other proposed developments along the Western Highway, the
area would appear as a rapid growing area of the country. A major housing
development is also presently located at mile 8, while others are proposed
for the areas around Burrell Boom and Hattieville. All these new and
proposed developments will benefit from this new landfill facility since
solid waste disposal is a serious development constraint facing developers.
In addition, a larger landfill would provide economic benefits over a series
of small uncontrolled sites for each development.
4.2.1.2 Existing Road and Traffic Conditions
4.2.1.2.1 Alternative Access Road
The Mile 22 landfill site can be accessed from the existing trail to the west
(Mile 24) and the existing right of way (Mile 22) east along the Western
Highway. This highway is in turn directly or indirectly connected to all of
BELIZE SOLID WASTE MANAGEMENT PROJECT
ENVIRONMENTAL IMPACT ASSESSMENT REVISED
December 2008 4.14
the other major road systems in the country hence facilitating access to all
the major regions. A gravel/dirt road once lead from the Western Highway
at mile 24 into the site. The first section of this road is generally in good
condition but would have to be significantly upgraded to meet the
anticipated heavy demands of traffic entering the landfill site. In its present
condition the road lacks surface drainage and portions of the roadway will
quickly become flooded, making it impassable in the rainy season. A box
culvert currently affords drainage along the Western Highway but further
in floods along one creek has washed away the road and access is only
possible over a makeshift bridge built of logs juxtaposed along the creek
bed. In addition, this area has several steel culverts in place which are in
poor condition. The land for this access route would have to be approved,
surveyed and purchased. In addition, without constructing a service road
400-500 m in length parallel to the Western Highway, poor visibility at the
approaches to the Western Highway at mile 24 will become a serious
impediment to using this road as the main access to the landfill site. Good
site access has been identified as one of the main criteria used in evaluating
the suitability of any landfill site (See section 3). The old entrance to the
landfill site lies near the top of a hill; the road rises as it meets the highway
along a ridge. The approach from the west has very poor visibility being
blocked by the land elevation at the Big Falls road cutoff, which lies at the
crest of the hill. To compound the visibility problem at this spot, the
highway takes a left turn after the Big falls road cutoff. In recent years,
there have been numerous fatal accidents at this location.
4.2.1.2.2 New Access to Existing Road
In 2006-2007 a new access located at about 1/4 mile away from the
previous entrance to the existing trail or dirt road was built by the Ministry
BELIZE SOLID WASTE MANAGEMENT PROJECT
ENVIRONMENTAL IMPACT ASSESSMENT REVISED
December 2008 4.15
of Work. This was done to allow for safer access since this access would
allow better visibility along both sides of the highway. In addition
Several sections of the existing trails were realigned and upgraded for
easier and safer flow of traffic. These works were being done following
recommendation contained in the STANTEC EIA of 2001.
Another alternative access along the property line that divides the Ramon
Property from Olympic Development and ABI was also investigated. This
route was eventually ruled out because much of it would have traversed
low lying marshy areas which would have increased the capital cost
associated with this activity tremendously. Since the landfill site must
have year round access, the road leading to it must allow for all weather
use and be able to withstand the anticipated heavy traffic and tonnage.
These criteria would indicate a need for a paved road surface with adequate
drainage installed.
4.2.1.2.3 Traffic on Western Highway
The present traffic count on the highway leading past this site is uncertain
but is believed to be on a rising trend mainly due to two factors:
Increased ownership of motor vehicles countrywide for example
between 1990 and 1998 there was a 65.8 increase in motor vehicle
ownership (Central Statistical Office, April 1999).
The increasing population of residential areas along the Western
Highway, in particular, between Belize City and Belmopan.
In 1995, 1998 and 2002, the Ministry of Works conducted three motor
vehicle censuses along the Western Highway and data was gathered to
access the frequency of highway usage. Data was collected at milepost 4,
BELIZE SOLID WASTE MANAGEMENT PROJECT
ENVIRONMENTAL IMPACT ASSESSMENT REVISED
December 2008 4.16
17 and 35. The traffic frequency data is summarized as follows. In the year
2006, Belize saw an increase in the number of vehicles that have been
involved in the scrap metal industry. In the period September to December
of 2006, the Department of the Environment, the agency responsible for
issuing License to Export Metal, recorded a total export of 1150 tons of
Scrap metal of which 1050 tons were exported via the Western Border with
the use of 71 heavy vehicles.
This industry further bloomed and in 2007 a total of 8807.5 tons of Scrap
Metal of which 8367.5 tons were exported via the Western Border with the
use of 672 heavy vehicles.
In comparing the Ministry of Works data and those of the Department of
the Environment, from the period 2002 to 2007, the amount of heavy
vehicles trafficking the Western Highway, being anywhere from Belize
City to the Western Border has seen a significant increase. (See Table 4.5)
The drop in traffic between miles 17 to 35 is perhaps accounted for by
vehicles using the Coastal Road which divert traffic coming from the 2
southern districts away from areas above La Democracia. This road is used
more often when weather conditions and road condition on the gravel road
are good.

4.2.1.3 Existing Topography
4.2.1.3.1 Topography and Drainage
The proposed Regional Sanitary landfill Mile 22 site will occupy a high
ridge near the transitional zone (Appendix E) between the pine-orchard
savannah and the broadleaf broken ridge forest. The site occupies the apex
of the ridge with the land elevation falling away rapidly to the north, south
and to the east. In the past, the northerly portion of this site was heavily
excavated for gravel road construction and remains in a heavily disturbed
state. It appears that the materials extracted here were highly favored by the
builders for road construction and that this was the main extraction site
along this section of the road. The site is full of borrow pits but evidence of
the depth of the digging can be found from the occasional outcroppings
containing large trees which exist throughout the site. Materials were dug
down to 4 meters deep. (Appendix E: Plates 2 & 9).
Since this extraction took place, surface erosion has cut deep ruts into the
exposed and eroded subsoils. Deep ruts run from the highest part of the
ridge in all directions but are especially pronounced along the eastern and
northern slopes, which as a rule, are generally steeper. The assessment of
the site for this study took place in the early part of the rainy season (late
June to July) during a low rainfall period. Very little standing water could
be found on the site, however it is believed that most of these borrow pits
will hold water during the rainy season. At the southern end of the
excavated area about 230 m. from the site apex lies a small unnamed creek
(Appendix E: Plate 8), flowing in a west to east direction. This creek is
about 2.5 m wide and 2 m. deep and collects surface drainage from the
south slope and some from the east and west slopes. This stream is joined
by another stream of similar size, flowing roughly from NW to SE. Beyond
BELIZE SOLID WASTE MANAGEMENT PROJECT
ENVIRONMENTAL IMPACT ASSESSMENT REVISED
December 2008 4.19
its confluence the stream enters a swampy marsh where it breaks into
smaller channels, which join before crossing the entrance road.
After crossing the existing entrance road the stream leads into a thicket of
broadleaf forest to the east of the site. The stream flows through this thicket
and then joins a major creek flowing northward from the box culvert under
the Western Highway. The creek eventually drains into Cox Lagoon and
then the Creek, which flows into Mussel Creek. This system then empties
into the Belize River.
The surface flow over the remainder of the site is towards lesser ordered
streams, many of them existing as localized troughs between the ridges and
are probably only active and distinguishable after heavy rainfall.
Nevertheless, the general trend remains the same. All drainage at this site is
towards the Belize River and its tributaries; mainly the Cox and
Mucklehany drainage systems. This means a general east and north flow
for the surface waters emanating from this site.
4.2.1.4 Soils and Geology
4.2.1.4.1 Regional Soils and Geology
The study area lies within the region referred to as the Northern Coastal
Plains of Belize (King et. al.,1992 ). This area contains mostly flat to
undulating topography, which are characteristic of the Belize River Valley
and Northern Belize. Most of the plain is underlain by Cenozoic limestone,
decreasing in age and hardness from the southwest to the northeast. The
natural forest cover over these limestone derived soils are semi-deciduous
broadleaf forest, however, often times these areas are interspersed with
areas of pine forest and orchard savannah over leached soils from the
BELIZE SOLID WASTE MANAGEMENT PROJECT
ENVIRONMENTAL IMPACT ASSESSMENT REVISED

Pleistocene alluvium (King et al., 1992). Soils of the Pinol Series, which
occur over the coastal deposits along the Western Highway, belong to the
puletan suite of soils. The undulating plain subunit has been characterized
as having soils of the Rough Mile series, while the high plain subunit is
associated with the Colonel English series, the alluvial wash with the
Haciapina Series, and the low plain with the Bocotora Series. The Rough
Mile Series soils have been characterized as vertic planasols (Miller and
Miller, 1995) in which the A2 horizon is weakly developed, grayish brown
in color and sandy loam or loam in texture. The B horizon is strongly
mottled clay, while the C horizon (45-100 cm depth) is gray and mottled
light gray or white, yellow, brown, and red. The clay subsoil contains
slickensides. The Colonel English Series soils comprise a thin gray loamy
sand A1 horizon overlying a bleached albic loamy sand or sandy loam
(Miller and Miller, op cit). The B horizon (at about 50 cm) is strongly
mottled gray, yellow, brown and red, which grades with a mottled clay C
horizon below about 100 cm. Miller and Miller (1995) noted that gravel
was common below the lower A horizon. The Bocotora sub-type is a pale
colored sandy topsoil over mottled red and white sandy clay subsoil, with
acid conditions. Low subsoil permeability and poor drainage were noted
(King et. al., 1992). Characteristic vegetation is pine savannah, in which
there were lower denser patches, providing for a more varied understory of
shrubs. The Haciapina subtype consist of deep, pale colored very wet sandy
topsoils over compact red and white mottled clay subsoils, which are very
poorly drained. The characteristic vegetation for the Haciapina was given
as pine savannah with minimal tree cover other than clumps of palmetto
(King et. al., 1992).
In terms of agriculture potential and land use, the undulating plain (Rough
Mile) was classed as “extremely small”, being limited by nutrients,
moisture and root room. Currently, the site is being used as a quarry for

road gravel and landfill. The high plain subunit (Colonel English) was also
used for gravel extraction. It was also classed as “extremely small” in
agricultural potential, as it is limited by nutrients, moisture and root room.
The alluvial wash (Haciapina) was assessed as “marginal”, being limited in
nutrients and drainage. Low plain areas (Bocotora) are limited by nutrients,
moisture and root room, and were classed as “extremely small” in
agricultural potential. A smaller area just west of Teakettle Creek falls into
the Beaver Dam Plains Land System which is the prevalent land series
north of the Western Highway. These vertisols occur on marl derived from
limestone (Miller and Miller, 1995), and have a high clay content (60-
90%). The dominant clay is montmorillonite, characterized by dry season
surface cracking, wet season intractability, and slicken sides with irregular
horizon boundaries. Very little cultivation occurs in this soil type, which is
limited by workability, root room and proper drainage. This soil was given
a “moderate” potential for agricultural value (King et. al., 1992). Further to
the west of the site are lands of the Lower Belize Floodplains, comprising
sub-units of alluvial wash, high bench and low bench. Soil types include
Meditation, Bermudian Landing and Lemonal. There is very little
cultivation, although there has been some pasturing on high floodplain
bench areas. The soil has good agricultural potential although it is
compromised by poor drainage and workability. To the north of the
Western Highway, are soils of the Neustadt Swamps Land Type, many
comprising sub-units of open savannah plain but with patches of low marsh
forest plain and marsh forest plain. Soil types include Chucum and Sibal,
with uses ranging from “very limited pasture” to none. Soils of the Chucum
subsuites are seasonal freshwater gleys which are poorly drained and
basically infertile (King et. al., 1992). Agricultural potential was rated as
“marginal”, with constraints from workability, wetness, root room and
nutrients. Typical vegetation (Appendix E: Plates 5,6 & 7) is low akalche
bush, with a high proportion of sclerophyllous shrubs (e.g., tinta, chucum

and stunted zapote) (King et. al., 1992). Sibal soil types are associated with
low herbaceous swamp vegetation, e.g., rushes and sedges, with some open
water supporting water lilies and other floating, emergent or sub-emergent
vegetation. In summary the Mile 22 project site is located on soils of very
limited agricultural potential being comprised predominantly of Pinol
Series soil types which provide “extremely small” to “moderate” prospects
for agricultural success without substantial inputs of investments and
technical know how. The site is of limited conservation value being well
represented within the national protected areas management system. It
should be noted that there are two principal vegetation types being
supported on the soils at the site. These are type 15 (Lowland Needleleaf
Moist Forest over poor soils) and type 4 (Lowland Broadleaf Forest over
poor or Sandy Soils) and according to Wilson (NARMAP, 1995) fully
17.7% and 32.9% of these were already represented in protected areas.
This percentage is likely to have increased significantly with recent
declarations of new protected areas and acquisitions into private reserves.
The situation in the surrounding area is less favorable in terms of protected
areas coverage and potential land use. Although most of the areas to the
south, east and north are of the Pinol series are well represented in the
national protected areas system, however the areas to the west are not. In
the region to the southeast are the Lowland Moist Evergreen Seasonal
Broadleaf Forest over limestone of the Central Eastern variant. The soils
that support this forest are well represented in the middle reaches of the
Belize River Valley and some within the Community Baboon Sanctuary,
however this is not a statutory protected area. Instead, this area relies on
the voluntary pledges of its members, hence long term security cannot be
taken for granted. In addition much of the soils to the northeast of the site
near the Belize River are of grade I and III agricultural values.

4.2.1.5 Geology and Soils of the Project Site
A 3 hole drilling and observation well installation program was undertaken along
with examination of the topography and drainage, and examination of quarry pits
at the project site. Thirty-four test pits were excavated in 2001 at various points on
the site, providing more information on sub-strata and suitability of the surficial
soils for landfill construction. The above observations, including stratigraphy, are
summarized in Appendix F, the Hydrogeologic Report for Mile 22, and a map of
the site showing the test pit and borehole locations is presented as Figure 3.2 in
the design set. At the proposed landfill site, there is a ridge which begins near the
existing entrance from the (new) Western Highway. It reaches a maximum height
about 17 m above the surrounding palmetto surface. The ridge has a core of clay,
limestone and marl with the gravel deposits draped over the sides. The area of the
proposed landfill appears to be covered by a thin layer of deposits containing
abundant granular materials. The granular materials are comprised of a matrix of
sand, silt and clay in which there are abundant pebbles. Beneath h this layer, there
is in most places an iron-stained sandy silty clay within which there are deposits of
white limey clay. At depths of about 1 - 3 m, the red staining gives way to white,
the sand and silt matrix disappears, and the material is a dense white clay. The clay
becomes progressively harder with depth. The red or white clay near the surface,
as observed in the holes or in the pits, is plastic with a low permeability. In situ
and laboratory tests on this white clay have established permeability in the order of
10 -9m/sec. Permeability is in simple terms: a velocity. The velocity of 10 -9m/sec
equates to a particle travelling a distance of about 0.3 meters per year.
Examination of the borehole and test pit logs gives a fairly consistent picture of the
underlying strata. Over much of the site, the topsoil has been removed by previous
gravel extraction activities; where some still remains, it occupies approximately
the top 1 to 3 meters. Typically, brown or red clay which is sandy or crumbly in
texture is encountered from about 10 cm to about 100 cm below the surface.
BELIZE SOLID WASTE MANAGEMENT PROJECT
ENVIRONMENTAL IMPACT ASSESSMENT REVISED
December 2008 4.24
Below this, there are typically layers of mixed red and white clay. White clay is
found below about 1.0- 2.0 m from the surface, the upper portions often being
crumbly, while the lower layers (to depth of drilling) are compact and dense. In
summary, the site is underlain by a thick layer grading from plastic clay to marl to
limestone. The clay has a substantial thickness and is of very low permeability. It
presumably would provide an excellent natural liner for the proposed sanitary
landfill. The granular materials lying on the surface at various locations on the site
could be used for developing on-site roads. The clay materials that would be
excavated in the construction of the landfill cells would be appropriate for both
interim and final covering of the wastes.
4.2.1.6 Surface Water and Use
4.2.1.6.1 Surface Water in Belize
While Belize is a relatively low country, its river systems and network of
perennial streams still provide most of its water needs (Hartshorn et. al.
1984). Streams in the mountainous areas drain along steep, straight
courses, while on the coastal plain savannah they become progressively
more sluggish. Numerous lagoons, mangrove swamps and estuaries form
as the slow moving rivers empty at the coast. The proposed landfill site is
located in the drainage basin of the Belize River, which for the purposes of
this report can be arbitrarily delineated as the areas north of the Western
Highway. The Belize River basin is presented as Figure 4.2. This
observation is not in agreement with the Watersheds Map of Belize which
shows the area as part of the northern boundary of the Sibun River
Drainage Basin. While the general premise of the map may be true, a
ground reconnaissance of the site shows that the streams flowing from the
site are flowing in an easterly direction towards the Belize River. To the
south of the highway the drainage basin of this river abuts the drainage
basin of the Sibun River, which drains a much smaller watershed than the
BELIZE SOLID WASTE MANAGEMENT PROJECT
ENVIRONMENTAL IMPACT ASSESSMENT REVISED

Belize River. A major culvert under the Western highway flows north
toward the Belize River.
4.2.1.6.2 Belize River Drainage Basin
Catchment Area:
The Belize River and its tributaries are the most important inland water
system in Belize, draining an area of 9,434.2 km2, which is a far larger
area than any other river system in the country. A large part of the
catchment of this river is in neighbouring Guatemala and this portion is
reflected in the above quoted figure. Because of its importance the flow
and drainage characteristics of this river system has also been the most
intensively studied of all the inland water systems of Belize. The
topography of the drainage system varies from west to east but can be
broadly divided between the coastal plains zone to the east and the higher
elevation areas to the west. The Coastal Plains section is below 100m ASL
and generally has slopes of less than 2%. In contrast the upper regions of
the river is highly dissected within a network of mountain basins and
plateaus with slopes ranging from 45-55% and elevations surpassing
1000m. In a study of Belizean water catchments to determine the relative
risk index for the various catchments, the Belize River scored the highest
and was therefore defined as the system most at risk.
Hydrology:
The numerous mountain tributaries of this river feed into a slow moving,
meandering coastal river prone to high flood peaks (+5m.). Rainfall varies
from 2,500mm in the highlands falling to 1,500mm along the coast and
even more along the north and northwest. Headwater stage increases of up
to 15m in a day occur at sub-basin confluences. The Macal River at Cristo
Rey experiences minimum flow depths as low as 1m and as high as 18m
BELIZE SOLID WASTE MANAGEMENT PROJECT
ENVIRONMENTAL IMPACT ASSESSMENT REVISED
December 2008 4.26
with flows well over 1000 m3/s Benque Viejo station shows that the Mopan
branch produces average daily discharges varying from 1m3/s to 275m
3/s
with an annual daily mean between 20 and 40m3/s. Peaks are attenuated
onto the coastal plain due the staggered flood water arrival through the
drainage network and shallowing of the channel. Average daily discharge
into the ocean is thought to be in the range of 155m3/s, however Double
Run has recorded peak flows in the range of 550-600m3/s and low flows
down to 10-20m3/s. At this location average daily flow is computed to be
100-150m3/s which are similar to those obtained for Banana Bank and Big
Falls Ranch further upstream.
Water Quality:
Water quality measurements depend on the timing of the test and flood
stage, but generally alkalinity and hardness of the baseflows are high and
decreasing as the higher flow (flood stage) kicks in. High sulphate levels
have been recorded and pH at baseflow is slightly basic. Several mid-size
point source pollution sites have been identified some originating from
domestic and small industrial outlets in San Ignacio and Spanish Lookout.
Other sources were identified at the waste water treatment plant at
Belmopan and Double Run (which supplies Belize City) and at plants in
Ladyville. BOD, pathogens and suspended solids were considered to be the
most significant contaminants with secondary sources ranging from
caustics to chlorine, oil and grease. It is likely that some non-point
agricultural runoff and flooding related input of sediments and organic
materials could be expected below San Ignacio. Sediment loads could also
be attributed to construction activities and the mining of materials for the
construction industry. Livestock grazing along the riverbanks may account
for one source of BOD and pathogens. There is some indication that illegal
dumping of pollutants occur in the river further upstream in Guatemala.

4.2.1.6.3 Water Use
The Belize River has played an important part in the historical
development of Belize. In the past this waterway was the main artery
connecting the coastal and western reaches of the country and although the
importance of this mode of transportation is now diminished, the river still
retains some importance in providing access to areas that are not accessible
by roads. In particular, the areas along the Belize River Valley. More
recently, the river has taken on another very important role. It functions as
a popular route for ecotourism tours, providing tourists the opportunity to
view some of the most scenic vistas in the country. The river also hosts the
annual La Ruta Maya River Challenge, one of the premier sporting events
in the country. In addition, the one tributary of the river (Macal) is being
tapped into for the production of hydroelectricity. The river provides the
main water source for all the major towns along its route including Belize
City. Table 4.7 shows major cities and towns water consumption.

Belize City, Belmopan City, Benque Viejo and San Ignacio all obtain their
water from the Belize River and its tributaries. In 2005 above two million
gallons were used and was on a gradual decreasing trend mainly attributed
to increase efficiency combined with efforts by consumers to conserve
water. Water is also being used for irrigation and various industrial pursuits
which are not calculated in the above figure, because the water was not
drawn from the metered municipal supplies. The surface water resources of
Belize are divided into 6 major basins with the Belize River forming the
third basin. The general profile of water resources in this basin is one of
high hardness, and high Sulphates, alkalinity and BOD levels (Water
Resources Assessment for Belize, 1998). It is believed that these can be
attributed to the indiscriminate dumping of organic matter into the river as
well as the burning of “milpas” and domestic and agricultural waste and
runoffs. It is also believed that some of the pollution can be attributed to
cross border pollution sources (Water Resources Assessment for Belize,
1998). The drainage system over the Mile 22 landfill site is decidedly
towards the east, with the available evidence suggesting that the main flow
is sequestered in the Cox Creek Drainage System which along with
Mucklehany Creek drains into Mussel Creek which in turn drains into the
Belize River upstream of Double Run Pumping Station. Mussel Creek and
its tributaries have been described as one of the most pristine and prolific
wetland ecosystem in Belize (Hunt and Tamarack). There have been
several proposals to declare this entire drainage area a protected area
especially for the protection of waterfowls and crocodiles (ibid). During the
dry season, the entire water system is heavily fished by residents along this
stretch of the Western Highway and by villagers of the communities near
Mussel Creek. Many of them are fishing for commercial purposes.
Recently, conflicts have arisen between local residents and fishermen from
BELIZE SOLID WASTE MANAGEMENT PROJECT
ENVIRONMENTAL IMPACT ASSESSMENT REVISED

outside the area over the use of these resources. To date very little of this
water is used for human consumption, agricultural or industrial purposes.
Within the landfill project site the streams are too small and seasonal in
nature to support any substantial water demand.
4.2.1.6.4 Drainage in the Project Area
As previously mentioned the flow of surface water from the areas
immediately around the project site is eastward and towards the Belize
River Drainage System notwithstanding the watersheds of Belize Map
which puts this entire area within the Sibun River Drainage Basin. The site
lies on a high ridge with the main flow of water being carried on the
northern and southern slopes. Along the western and northern slopes the
water is carried along a drainage slope with gradients of 2-5% from which
it enters the numerous on-site erosion channels that has formed as a result
of the quarrying activity Along the eastern and southern slope the water
follows a less direct route but again the general direction of the drainage is
towards the east. Surface drainage from these slopes is collected in erosion
channels and collected in two streams. The first stream carries the bulk of
the surface drainage from the proposed site being situated immediately to
the bottom of the steepest portion of the ridge. This stream flows in a SW
to NE direction. It is about 2.5m wide and 2m deep and has numerous
sandbars which have resulted from the deposition of eroded sand and
gravel from the quarry site. This stream is seasonal in its flow patterns.
Evidence indicates a complete drying out, at least during the latter parts of
the dry season. In the assessments conducted at the site in July, 2001, all
streams at the site showed very low flow with many instances of ponding
observed. It should be noted, however, that rainfall for this period was also
below average. This stream is joined along the eastern boundary of the
proposed site by another major stream flowing from the NW to SE. This
BELIZE SOLID WASTE MANAGEMENT PROJECT
ENVIRONMENTAL IMPACT ASSESSMENT REVISED
December 2008 4.32
stream also shows signs of heavy deposition of sediments washed from the
site and carries most of the water from the eastern and northeastern flanks.
Shortly after converging, the stream flows into a low thicket area where it
breaks up into a swampy marsh, partly reconfiguring before crossing the
existing access road. About 2 km east of the site the stream enters a thicket
nurtured by water flowing from the area south of the site. This water course
eventually drains into Cox Creek. Further to the south about 2 km from the
landfill site along the Mile 24 existing access road, is another creek, which
also flows in a west to east direction. This creek collects surface drainage
from the remainder of the southern slope and from the outlying pine
orchard savannah areas to the south. Because this creek serves a larger
drainage area, it is bigger than the other two creeks found on the site. Over
time, the creek has supported a thicket type broadleaf forest along its
banks. This creek will receive the bulk of the surface water runoff from
areas surrounding the waste disposal facility.
In summary it is very important that contaminated water does not leave the
landfill site given the importance of the Belize River Drainage system and
its tributaries to the national economy and to conservation purposes in
general. This water system is heavily drawn upon for domestic, agricultural
and industrial consumption and of late has become an important icon of the
tourism industry and recreational endeavours in general. The tributaries of
the Belize River, near the project site are well known wetland areas, and
have long been regarded as among the most pristine and prolific in Belize,
as well as being recognized as an important gap within the “National
Protected Areas Management System”. These wetlands are now being
heavily exploited for their fishery resource often for commercial purposes
and it is believed on an unsustainable basis. The footprint of the landfill is
totally within one drainage basin. The surface water systems of the
proposed landfill are to be designed to handle the entire basin shown on

Figure 3.4. Surface drainage from the landfill site is generally towards the
east, however these drainage patterns once clear of the landfill site, are
diverted towards the west by drainage systems coming from the south of
the Western Highway and flowing northwest and west.
4.2.1.7 Ground Water and Use
All work, and the subsequent interpretation, has followed the intent and the spirit
of World Bank (Rushbrook and Pugh, 1999) regarding the approaches, methods
and technical resources available in middle and lower income countries with
respect to landfill ground water investigations. Specifically, it was recognized that:
“Most existing guides on sanitary landfill focus on technologies and practices most
suited to the conditions and regulations found in higher-income countries. These
are often based on attaining extremely high levels of protection for aquifers,
incorporating aesthetic concerns, high levels of leachate treatment, and controls to
assure low noise and low gaseous emissions. The immediate adoption of some of
these technologies and practices are beyond the technical and financial resources
available in many middle-and lower-income countries”. “… A common theme
through the Guide is the emphasis on the practical ways landfills can evolve, as
resources and confidence can increase, from open dumps to “controlled” dumps to
“engineered” landfills and perhaps, one day, to sanitary landfills…” Belize is most
certainly in the early staged of the “evolution” of their landfill.
A detailed Hydrogeologic Report is presented in Appendix F of this document.
Hydrogeologic data quoted in work conducted southwest of the project site (Jih
Chan Project). Miller and Miller, 1995 indicated that the underground aquifer in
the region is in the deep limestone layer. This work suggests that productive wells
may need to be drilled 60 or more meters below the surface to provide a year-
round supply of good quality water. There are three wells in the general area of the
proposed landfill site which provide some information on groundwater resources.
BELIZE SOLID WASTE MANAGEMENT PROJECT
ENVIRONMENTAL IMPACT ASSESSMENT REVISED
December 2008 4.34
Unfortunately, because of the remote location of the site and low population
density of the surrounding area, a closer sampling site could not be identified and
therefore, the extrapolation runs the risk of being conjectural. There is an active
well within about (10 km) of the landfill site, situated at the Tropical Education
Centre. The depth to water is about 12 m below the surface. The well at Jih Chan,
about 4 Km to the southwest is completed in a sand lens above the limestone
bedrock. Another wall at Gracy Rock above 10 Km to the southeast is completed
at depth into the limestone. All three observation wells on site initially did not
show water to the maximum drilling depth of 15 m. The fact that dry conditions
were encountered until 15m depth, attests to the low hydraulic conductivity of the
clay materials. After a period of time, the observation wells indicated some ground
water at a level of 4 to 6 m below surface. Based on this information, it is evident
that the groundwater under pressure in the limestone might be encountered below
15 m, relative to the lower landfill elevations.
Summary:
It is evident that the groundwater under pressure in the limestone would be
encountered at some depth greater than 15 m below surface, relative to the landfill
lowest elevations. Above this, there are thick layers of clay material of
considerably low hydraulic conductivity. Artificial liners would not appear to be
necessary at this site, which appears to be an excellent one from a groundwater
perspective. It is extremely unlikely that groundwater or any local wells would be
affected by the development and operation of the landfill.

4.2.1.8 Climate and Meteorology
4.2.1.8.1 Climate
Belize is situated in the outer tropics or sub-tropical geographic belt. Mean
monthly minimum temperatures range from 16-17 degrees in winter, to 24-25
degrees in summer, with mean monthly maximum ranging from 28 degrees in
winter to 32-33 degrees in summer (Hartshorn et al., 1984). Temperatures are
cooler in the mountains, while along the coast the offshore breezes bring moderate
temperatures. Seasonal effects are greatest in the drier central and northern
regions. In the area of the proposed Mile 22 landfill (17o22’N x 88
o33’W) and in
Belize in general, the predominant winds are from the east, i.e., from ENE to SE .
In this region of Belize, the wet season is from June to December, with a short dry
spell in August, and a dry season from January through May (see Table 4.8).
While prevailing winds are easterly, in the cooler months (October to April) winds
from the N and NW, affect the country and are the dominant weather feature
during this time. These winds called “Northers” are pushed down from the north
by cold arctic air masses. Northers generally follow a cycle entering the country
from the NW and N and bringing cool dry air masses. Often times after the
Northers has passed over, the wind shifts to the NE and these are often associated
with cool and wet weather, indeed most of the rainfall occurring in these months
can be attributed to the influence of these weather systems. Tropical storms and
hurricanes also affect Belize, resulting in strong winds, heavy rainfall and flooding
(see Figure 4.2). Although only 5% of cyclones recorded in the tropical Atlantic
Ocean reached Belize between 1886 and 1978, the country has had a history of
devastating encounters with tropical cyclones (Hartshorn et al., 1984) .

4.2.1.8.2 Wind
Although detailed wind data does not exist for the proposed landfill site, there is
data for the Philip Goldson International Airport located near Belize City. Monthly
wind data from the Airport from 1961 to 1996 shows that wind direction is
predominantly from the east and to a lesser extent the southeast, with some
seasonal winds from the north, northeast and northwest. Relatively rarely do winds
blow from the west, southwest or south, and when they do it usually means
adverse weather conditions. The wind speed is normally between 1 and 12 knots,
with still conditions being reported 18% of the time at the airport location. The
mean annual wind speed was assessed as 4.8 knots. Being some 20 miles (32 km)
inland, the wind conditions at the proposed landfill site may differ somewhat from
the above data, but the directional data should not be significantly different except
at nights when the wind direction generally changes and the sea breeze is replaced
by a land breeze. This phenomenon is especially pronounced during the cooler
months and is caused by the rapid cooling of the land at night. The associated
temperature difference is more pronounced as one moves further away from the
coast.
4.2.1.8.3 Rainfall
Rainfall data are given in Figure 4.3 for various locations in Belize including the
Belize International Airport. Figure 4.4 gives a summary of rainfall statistics for
the Belize International Airport , and the country average annual rainfall showing
that in 2003 Belize experienced low rainfall with the average rainfall being
approximately 1,692-2,134 mm rainfall. Figure 4. 5 shows the isohytes map for
Belize showing the project area as receiving approximately 60 inches (1524 mm) -
80 inches (2032 mm) of rainfall. The 1/100 year 24-h return storm event at Belize
Airport is 327 mm, while for Melinda (inland), the corresponding figure is 269
mm, and at Savanna it is 217 mm. The maximum 1/100 year 2-h return storm
event for Belize Airport (1983-1994) is 179.1 mm. The period from June to

4.2.2 BIOLOGICAL ENVIRONMENT
4.2.2.1 Flora and Fauna
4.2.2.1.1 Flora and Fauna of Belize
Belize has an impressive assemblage of flora and fauna that has managed to
survive, thanks largely to the large chunks of the country that have been set aside
as protected areas. The country has as much biological diversity as any other
Mesoamerican country at similar altitudes and is aided in its conservation efforts
by the presence of extensive areas of relatively undisturbed habitats and its low
population levels. As of June 2000, the country had 58 protected areas under
designations of Forest Reserves, Private Reserves, Crown Reserves, Nature
Reserves, Natural Monuments, Wildlife Sanctuary, National Parks and Marine
Reserves. This gives a total area of 1.04 million ha., out of a total land area of 2.18
million ha. or 47.7% of the country excluding territorial waters. With the recent
declaration of additional protected areas this amount will have increased
accordingly. With the new emphasis on biological corridors, the strategic location
of the country on the “land bridge” connecting North and South America assumes
new importance. Indeed many of the plant species found in Belize have affinities
from both regions although a sizable portion are endemics including many species
found in the pine/orchard savannah habitats. Affinities to the Yucatecan and
Campechean botanical provinces are particularly strong for the northern region of
Belize which includes the project area (Standley and Record, 1936). In 1994 fully
79.0% of the country was under one of 12 broad categories of forest cover. During
the same period approximately 25,000 hectares were being lost annually, most of it
due to agricultural expansion. This represents 1.1% of the total land area of Belize
and although not large by regional standards still leaves no room for complacency.
Table 4.9 gives the approximate amount of forest cover for the different forest
classes (based on physiognomic and edaphic features) in mainland Belize in 1994.

Since some transformation of the landscape has taken place in period between
1994 and 2001, the information in the table should be treated as indicative. Many
of the forest types mentioned above can be easily broken down into sub-categories.
Nevertheless, the central premise stands that the country has remarkable botanical
diversity, and in its conservation efforts is operating from a position of strength
dealing with mostly intact ecosystems. On the basis of the Holdridge Life Zone
Classification System, the proposed landfill site is located near the transition zone
between Tropical Moist Forest and Subtropical Wet Forest life zones, which runs
along the coast, south of the Western Highway. Of the 3410 species of plants

identified for Belize 57 are considered endangered representing about 1.7% of the
total amount (Belize National Biodiversity Action Plan, 1998).
Belize continues to offer refuge for a range of faunal species that are under
pressure or endangered in the neighboring countries. A distinct advantage favoring
the preservation of these species in the Belizean conservation context lies in the
fact that most of these species exist in a fully functional ecosystem. The country
has attracted considerable attention from international conservation organizations
for these attributes and because the country lies on established migration routes for
both neotropical and nearctic species which in the case of the latter are almost all
endangered. Table 4.10 presents the number of faunal species for Belize.

4.2.2.1.2 Vegetation of the Study Area
Vegetation zones of the project area and surrounding areas are shown in Figure
4.1. As with most vegetation mapping exercise of this type the information given
is at best an approximation given that vegetation types are seldom homogenous
and are as a rule very complex and varied especially under tropical conditions. In
addition many forest types in this region look to outward appearances as
structurally similar but in reality differ markedly in species composition. For this
reason accurate vegetation maps are hard to come by, but the Revised Natural
Vegetation Map for Belize (Brokaw and Iremonger, 1996) has gained currency in
natural resource management circles as one of the most accurate. All descriptions
given in the following discussion are based on the authority of these maps and the
detailed ground truthing efforts of the field assessment team commissioned by this
study.
To better document the study area a series of quadrants were established over the
study site measuring 20m by 20m. These quadrants were placed at random
locations along lines running from the center of the site along a north, east, south
and west bearing but with particular attention to placement within distinguishable
forest types. All identifiable plant species within the quadrants were then recorded,
and shown on Table 4.11. The project site lies mainly within a vegetation
community type known as the “fire induced shrublands of the plains (Belize)” (see
Fig. 4.2). This general area of scrub forest applies to the project site and most of
the areas to the north, east and south of the site. Within this general area however
are stretches of broadleaf forest oasis along streams and clumps in low lying,
marshy areas. The western boundary of the site forms a part of the transitional
zone between the pine/orchard savannah region and the lowland broadleaf forest.
This forest type can be referred to as Lowland Broadleaf Wet Forest over Poor or
Sandy Soils sometimes referred to in local jargon as “broken ridge forest”. It forms
a conspicuous presence along the central ridge and the western boundary of the
site. Further to the west, the forest differentiates into Lowland Broadleaf Moist

As previously mentioned most of the vegetation at the site belong to scrub or scrub
dominated communities. Plants within scrub communities are generally less than
5m tall and their collective canopy coverage do not normally exceed 30% of the
total land area. Many of them exhibit qualities of mesophytic species such as their
ability to withstand water stress and seasonal wildfires. Trees are mostly multi-
trunked and woody. Falling within the general definitions of scrubs are shrublands
which are defined as wider spaced scrubs where individual crowns are generally
not touching. Within these scrub communities are occasional thickets induced by
better year round access to moisture and which are generally defined as closer
spaced with many of the crown touching each other. At the site characteristic
species associated with these thickets are Palmetto (Acoelorrhaphe wrightii),
Black Poison Wood (Metopium brownii), White poison Wood (Sebastiana confusa
Lundell), Miconia spp and cockspur (Acacia spp). Besides these, there are the
seasonally waterlogged scrub with much Miconia spp., which are prevalent
throughout the site although only in small patches. In some patches up to 5 species
of miconia were observed usually in associations with Craboo (Brysonima
Crassifolia), Coco Plum (Chrysobalanus icaco) and Negrito (Simarouba glauca). In
the areas classified as Fire Induced Shrubland of the Plains the general description
is best given as grass dominated stretches with interludes of scrub patches some of
them merging and others existing as separate and distinct patches. Characteristic
tree species in this area are Palmetto(Acoelorrhaphe wrightii), Craboo(Brysonima
Crassifolia, Oak (Quercus Oleoides), Yaha (Curatella americana), Cocoplum
(Chrysobalanus icaco), Calabash(Crescentia cujete) and ferns in the understory.
Caribbean Pine (Pinus caribaea) is also associated with this vegetation type
although for most of the project area it does not occur in stands probably because
of prevailing unfavourable soil and water conditions but also because of past
logging activities and frequent and uncontrolled fires. At the project site, pines are
thicker and have better growth characteristic probably aided in regeneration by the
disturbed soil surface and access to the nutrients from the exposed subsoil layers
which are richer than the leached upper soil horizons.

The Lowland Broadleaf Wet Forests over Poor or Sandy Soils typically occupy the
transitional areas between the pine savannah and the broadleaf forest proper. This
forest type occupies part of the ridge at the project site and the areas along the
site’s western boundary. The soils are typically sandy loam but along the edges of
streams and gullies they can be reddish brown clays and dotted with small pebbles.
Species typical for this area are Nargusta (Terminalia amazonia), Madre de Cacoa
(Gliricidia sepium), Polewood (xylopia frutescens), Billy Webb (Acosmium
Panamensis), Santa Maria (Calophyllum brasiliense), Miconia spp., Negrito
(Simarouba Glauca), Red Gumbolimbo (Bursera simaruba), Dumbcane
(Dieffenbachia sequina) and Cutting Grass (Scleria bracteates). The entire
ecosystem in this area except for the broadleaf forest areas has developed under
the influence of fires which run through this area on a yearly basis. Normally the
broadleaf forest are not affected by wildfires except along the fringes but in
exceptionally dry years which on average occur every 10 – 20 years wildfires are
known to run into broadleaf forest causing considerable damage. The forest types
occurring within the project area are well represented in Belize and most
importantly within the existing protected areas system. In addition, most of the
land in this area have marginal value for agriculture (Grade IV and V soils) and are
mainly used for residential purposes, gravel extraction, and small scale logging.
Despite their limited value for agriculture and forestry development these areas are
nevertheless important ecological domains. The pine savannahs and their
transitional areas are known to contain a high proportion of Belizean endemics
(Dwyer and Spellman, 1981) suggesting that many of these habitat types may be
unique to Belize or have very limited representation beyond our national
boundaries. In addition, although some of the species present may occur over a
large area their density in any of these locales may be extremely low.

4.2.2.1.3 Wildlife of the Study Area
Since its return to the feral state, the area of the proposed Mile 22 landfill site has
become prime bird habitat and a favored nesting site for many species of birds
most notably the members of the flycatcher family. Larger mammals such as
ungulates and feline species are conspicuously absent but anecdotal evidence
suggest that they have a presence in respectable numbers in the broadleaf forest to
the west. During reconnaissance and field visits to the site in July, 2001, the study
team detected deer tracks and tapir droppings in the creek beds. Because of its
location at the edge of the Pine/Orchard Savannah near the transitional zone
entering the broadleaf forest, the proposed Mile 22 landfill site offers a variety of
feeding and nesting opportunities for a host of wildlife, especially birds. The
convenient foraging in the nearby hardwood forest, and the relative sanctity and
isolation of open forest for nesting in the scattered trees, safely out of the reach of
most predators, combine to provide wildlife with multiple advantages. The
transitional forest at the site is also more species rich in plants producing many
of the fruiting trees favored by birds. The open conditions are also ideal for birds,
which prey on insects which breed on the edges of the broadleaf forest. Previous
disturbance to the site may have actually increased the appeal of the site to some
species who subsequently moved in to colonize it, often at the expense of species
that are less tolerant to habitat disturbance. On one occasion, during a four hour
period, the study team counted 55 species of birds, all of them residents (consensus
was among all). It is believed that the total number of species would increase
during the overwintering period for Northern migrants and these would normally
contain a high proportion of endangered species. A large number of nesting sites
were also observed, in some instances registering as high as a dozen nest on some
trees in the higher ridge areas. A listing of the bird species identified is provided in
Table 4.12. Although of the parrot species only the White Fronted Parrot were
BELIZE SOLID WASTE MANAGEMENT PROJECT
ENVIRONMENTAL IMPACT ASSESSMENT REVISED
December 2008 4.52
seen during the field visits it is assumed that the site will also harbor the
endangered Yellow Headed Parrot. The open savannah areas with scattered pine
such as is typical at the Solid Waste Disposal Site are favored by this bird and their
absence may be attributable to their abandonment of the nesting area after the
fledglings have vacated their nest in late May and early June. This study made no
structured attempt to document other mammalian species in the area other than
opportunistic sightings and extrapolation from signs such as tracks, droppings etc.
According to loggers camped out at the site encounters with game species in the
nearby broadleaf forest were common. Specific mention was made of sightings of
Collared Peccaries, Brocket Deer, Pacas, White Tailed Deer and Nine Banded
Armadillo. At the site, the tracks of one White Tailed Deer and the droppings of a
Bairds Tapir were detected in the stream bed. It is believed that wildlife from the
nearby hardwood forest will come out especially at nights to browse on the burnt
savannah edges and to feed on the fruits of Craboo, Oak and Palmetto.
The absence of the large predators within the study area should not indicate their
absence from the region. Reports of jaguar depredation on cattle are common in
the Big Falls Ranch area and along the Burrel Boom/ Hattieville Road. The large
territory required by these animals would suggest that they may pass through this
area, en route to their main hunting grounds. In addition, during geologic testing,
an ant eater, two grey foxes and a paca were observed along the existing access
trail.

The areas between miles 24-27 are considered an important link in the National
Biological Corridors Network providing an important link for species requiring
habitat linkages between the northern plains of Belize and the Maya Mountains
and Mountain Pine Ridge Massif. From an ecological viewpoint the Western
Highway can be regarded as an ecological barrier splitting the country into a
northern and southern zone along its mid section and being obstructive especially
to the movement of obligate terrestrial species. The recent proliferation and
expansion of settlements along all portions of this road has served to acerbate this
problem. The area between miles 24-27 was long regarded as one of the few
remaining and most promising corridor offering a relatively undisturbed area with
few large settlements. Recent events, most notably the planned construction of
large residential communities has changed much of this thinking but the idea
remains in vogue that a few managed areas at this location could still be viable
albeit at a reduced level than was originally planned. Besides its obvious
importance as a biological corridor route, the areas to the west and northwest
contain important wetlands that are of great importance to waterfowls and migrant
species and therefore are of great conservation concern. This waterway complex,
including Cox Lagoon and Creek, Mucklehany Lagoon and Creek and Mussel
Creek offers refuge to thriving populations of Morelets Crocodiles (Crocodylus
morelet) and wading birds. The waterways support abundant ichthyo fauna
including turtles and in this regard is one off the last remaining refuge for the
endangered Central American River Turtle (Dermatemys Maweii) the last member
of its family to survive anywhere in the world. ). The endangered Caribbean
manatee (Trichechus manatus) are also known to frequent these waters. An
additional (but often overlooked) role of these waterways is that they support the
food chains on which many other species rely for their survival. Several proposals
have been forwarded to have this area declared a protected area. These efforts
continue and are likely to intensify as the biological corridors network takes shape.
In the meantime this important watershed should be carefully monitored if for no
BELIZE SOLID WASTE MANAGEMENT PROJECT
ENVIRONMENTAL IMPACT ASSESSMENT REVISED

other reason than for the important role it plays in controlling drainage from this
general area into the Belize River.
Summary:
The location of the proposed Regional sanitary Landfill at Mile 22 site is
predominantly in Pine/Orchard Savannah dominated by scrub vegetation,
supported on soils of marginal agricultural value and well represented within the
current protected areas network. Because parts of the area are heavily disturbed,
the site has little commercially useful timber resources and few conflicting land
uses. The site, however, is located next to a series of complex and fragile habitats
and supports a vibrant avifauna population located near the transitional zone
between the broadleaf and open forest ecosystems. The general area has been
proposed as a route for the proposed biological corridors complex linking the
northern and southern regions of Belize. On present evidence
the viability of this route is being seriously threatened by development and
although it may survive it is liable to be of a greatly diminished scale and
importance. The drainage area of this site support a complex wetland system that
offer sanctuary to many species of international conservation concern.
4.2.2.2 Sensitive Habitats
Although the site (within the national context) cannot be considered critical
habitat, it is close enough to influence other sites which fall into this category
mainly due to the drainage patterns emanating from the site. During the field
reconnaissance no particularly sensitive plants or animals were detected, and it is
highly unlikely that any will be discovered given the heavily disturbed condition
of parts of the site. The heavy concentration of nesting for avifauna species
particularly flycatchers is purely opportunistic and any displacement from this site
BELIZE SOLID WASTE MANAGEMENT PROJECT
ENVIRONMENTAL IMPACT ASSESSMENT REVISED
December 2008 4.56
(temporary or long term) should not threaten the viability of any of the species in
that area given the abundance of similar habitats in the surrounding regions.
Even though the site does not contain sensitive species or habitats per se it falls
within an area of conservation importance. Its location adjacent to a proposed
corridor route between miles 24-27 should be sufficient cause for its automatic
upgrade in importance as a conservation management area that allows easement to
wildlife by providing the necessary cover plus feeding and foraging opportunities.
Any development at the landfill site must take this very important consideration
into account. The maintenance of a treed buffer zone along the boundary of the
waste disposal site and along the boundaries of seasonal streams can create a
cordon sanitaire from visual and odor impacts while creating a corridor for the
movement of wildlife both during and after the operational phase. This final
configuration could be planned to fit in with the concept (i.e., gently sloping
savannah with some shrub cover, etc.). It is to be noted, in this respect, that even
during the operational life of the landfill project, only 15-20% of the site will be
used at any given time while the rest will remain undisturbed or reclaimed.
Whereas the site is not ecologically sensitive, because of its location and the
characteristic of its drainage systems, it can influence other sensitive areas along
its watershed which includes an important network of wetland areas. The utmost
diligence will have to be exercised to prevent contamination of these waterways
with untreated waste.
4.2.3 SOCIO-CULTURAL ENVIRONMENT
4.2.3.1 Past Use of Proposed Site and Historical Resources
4.2.3.1.1 Historical Resources
The potential for significant historical resources in the proximity of the
proposed Mile 22 sanitary landfill site is very low. The highly disturbed
BELIZE SOLID WASTE MANAGEMENT PROJECT
ENVIRONMENTAL IMPACT ASSESSMENT REVISED
December 2008 4.57
and exposed nature of portions of the site, the fact that the area has been
well covered in terms of reconnaissance surveys, with no structures or
artifacts being discovered and none being indicated on any current
archaeological map all support this finding. Historic resources of note were
located near Gracy Rock, about 12 km east of the landfill site (Mr. Brian
Woodye, Associate Director, Institute of Archaeology, pers. comm., 1999).
At that location, there are caves and evidence of settlement of Mayan
origin. Another site where historic artifacts have been found is on the Sibun
River, south of the proposed landfill site. Here, too, the articles found were
associated with a Mayan settlement area and with the existence of caves.
Anecdotal evidence suggest an additional site in the area of Cox Lagoon
about 7km. NW of the landfill site, but it is believed that these mounds
represented a minor ceremonial center. The Belize River is known to have
been a major trade route of the ancient Maya, and artefacts from their camp
sites are found all along and within the river. The region on the other side
of the Belize River WNW of the landfill site along Laboring Creek has
numerous Maya Mounds especially in an area locally referred to as Narras.
While it is not likely that any historic artifacts would be found at the site,
“mounds” containing Mayan cultural remains are sometimes found away
from caves, river routes and other indicators of high archaeological
potential. However, the site has been visited extensively by the project
team in the past half year without observations of any such remains.
An inspection by the IoA representative on August 1, 2001 indicted there
were no visible presence of cultural material in the project area. The
disturbed area also indicated that there are no sub surface features. A
written report was forwarded to the Department of the Environment in
Belmopan and is included as Appendix I to this report. Notwithstanding the
low probability of finding articles of historical interest, in the unlikely
event that such items were to be uncovered during site preparation or
BELIZE SOLID WASTE MANAGEMENT PROJECT

construction, the operators are advised to contact the Institute of
Archaeology (Belmopan). The Institute can then assess the importance of
the material and provide direction in terms of collection or preservation of
the material.
4.2.3.1.2 Past Uses of the Proposed Landfill Site
While any use of the proposed site in the Archaic period would have been
ephemeral, in the modern era there is much evidence of use. Portions of the
site was first opened about 20-30 years ago to provide ballast for the
construction of the Western Highway. The materials at the site are suitable
for the purpose since they contain a high proportion of gravel, which is
much favored by road builders. It appears that the site eventually became
one of the main gravel pits along this stretch of the highway judging from
the degree and extent of the excavation. The remoteness and generally
good accessibility of the site has attracted other activities of a less
reputable nature. At least 1 vehicle has been scrapped near the site by
criminals and another burnt. During the field studies loggers operating NW
of the area were using this site as a temporary camping grounds.
4.2.3.2 Land Use and Demography of Surrounding Neighbourhoods
The sparse settlement patterns along this stretch of the Western Highway is a good
indicator of the limited agricultural potential of the soils in this area. In the past the
economy was based on agriculture and forestry and settlement patterns often
reflected opportunities to pursue these endeavors. With the diversification of the
economy away from agriculture into industry and services, these areas are being
looked at again as potential sites for residential development. Notwithstanding
this, considerable stretches of lands in this area are still uninhabited. Most of this
land is being held by a few large land owners many of whom have plans for
BELIZE SOLID WASTE MANAGEMENT PROJECT
ENVIRONMENTAL IMPACT ASSESSMENT REVISED

residential communities in their development planning prospectus. Most notable in
this regard are Ramon Development Ltd., Olympic Development Ltd., Black
Orchid Gardens (ABI), Jih Chan and , Mahogany Heights (See figure 3.6
showing a survey map of proposed development). The nearest dwellings are
located along the Western Highway about 5 km SE of the site. In this tiny enclave
3 households were identified; 2 on the north side of the road and 1 on the south
side. Apart from small home gardens the residents do not engage in farming and
indeed the surrounding swampy and infertile landscape (grade IV to V agricultural
land) offers little opportunities to pursue careers along this line. Jih Chan is the
only sizable residential community existing near the landfill site. It is estimated
that approximately !75 persons live at this community. This development is
located about 4.5 km SW of the proposed Mile 22 Sanitary Landfill Site. It has
many of the structures normally associated with an established community
including roads, drainage, potable water and electricity. The community also has a
store and there is some agriculture, mainly dedicated to vegetable production.
4.2.3.3 Planned Development Activities
The Jih Chan Development was supposed to encompass lands on both sides of the
Western Highway at mile 25. This development was projected to have a
population of about 76,000 people on completion and would have come replete
with shopping centers, retail outlets, light industry, landfill, parks etc. To date only
a small development has taken place on the lands to the north of the highway. A
total of 35 houses have been built with no new one occurring for the past five
years. Ramon Development has property that includes the SW half of the proposed
landfill site and extends to the southern side of the Western Highway bordering on
the Sibun River. The company proposes to establish a residential community with
a projected population of 18,000 persons. Presently all of this land except for a
small portion along the Sibun River lies in an undeveloped and natural state.
BELIZE SOLID WASTE MANAGEMENT PROJECT
ENVIRONMENTAL IMPACT ASSESSMENT REVISED

The property of Olympic Development Ltd occupies the northeastern portion of
the property. This property and the nearby ABI property are also proposed for
residential development but in their current condition are totally undeveloped.
The new residential development at mile 31 Western Highway, known as
Mahogany Heights, has changed the regional demographics somewhat. The town
was supposed to have a population of 20,000 persons but only a fraction of this
amount actually reside here. All the proposed services and amenities of the site
have not come to fruition. Development to date has been limited to approximately
350 residential dwellings as well as streets and drainage, however, little else of
associated infrastructure has been provided. All existing and proposed
communities in this area stand to benefit from the close proximity of the proposed
landfill site. The provision of adequate waste disposal facility has been a stated
concern off all developers in the area. In addition, the construction of one large site
will offer economics of scale over several small sites for each development. The
location of the facility near these developments will cut transportation cost for
waste disposal, while encouraging a general cleanup of the area by reducing
incidences of illegal dumping. In addition some of the developers may benefit
from the upgrading of the entrance road to the landfill site since it will facilitate
entrance onto their property.
4.2.3.4 Other Important Developments
Big Falls Ranch situated NW of the site is a large property that was in previous
years a center for rice cultivation and processing in the region. The main produce
is now beef cattle but the owners had indicated an interest in resuming rice
cultivation (pers. comm.) at some future date. The farm maintains a small staff and
is about 14 km from the site. Entrance to the farm is located a short distance to the
west of the present entrance to the landfill site.

4.2.3.5 Public Sensitivity and Potential Concerns
4.2.3.5.1 Previous Contacts with Stakeholders
Many of the concerns previously expressed in Public Meetings for the
other site are still valid for the Mile 22 Sanitary Landfill Site, however
their effects are strongly mitigated against by the general remoteness of the
facility from human habitation or facilities. Mitigation measures will also
be put in place at the landfill site to ensure that no adverse environmental
affect arise as a result of the placement of this facility at the proposed
location. The adjacent stakeholders were invited to a meeting on Jun 1,
2001 and appraised of the project. Minutes of the Stakeholder Meeting are
presented in Appendix D. In due course of time notices were placed in the
print media informing all members of the public about the project and
invited their inputs and suggestions, as required under the EIA regulations.
The consultations had specifically targeted the local stakeholders whose
main concerns were centered on the following issues:
Surface and Ground Water Quality
Several stakeholders expressed concern that the proposed landfill might
lead to contamination of surface water and ground water, either by surface
runoff coming into contact with the waste or by leachate entering the
surface water. It was feared that contaminated surface water could reach
the Belize River via the network of creeks. Another concern was in the
susceptibility of the area to flooding, which could cause the holding ponds
to overflow in a heavy rainfall period, again posing a threat to the Belize
River.
BELIZE SOLID WASTE MANAGEMENT PROJECT
ENVIRONMENTAL IMPACT ASSESSMENT REVISED
December 2008 4.62
4.2.3.5.2 Community Participation and Benefits
Stakeholders expressed a desire to be involved in the waste management
project. Specifically, it was suggested in this EIA that they be involved in
the ongoing monitoring during the operations. In this way, these
stakeholders could act as an additional and objective source. This could be
integrated with on-site monitoring of surface water runoff, ground water
and leachate, to develop an ongoing picture of water quality trends, and
serve as an early warning system for any changes that might result from the
waste management program. It is recommended that there should be an
open relationship between stakeholders and planners in the design of the
waste disposal facility. In addition, there is the need for a training program
for those involved in the monitoring program. Other benefits to the
communities will be in the form of paying jobs, which could include their
involvement in the collection of solid waste that exists along roads and
other unauthorized dump sites, once the disposal system has been set up.
This approach should also be adopted for the Mile 22 site also.
4.2.3.5.3 Project Economics
Stakeholders felt that the overall project economics of building a site in a
remote location should be presented as part of this exercise.
4.2.3.5.4 Advocacy Process
Stakeholders were aware that the advocacy process had caused the GOB to
pursue an EIA process for the Mile 22 site. Concern was raised with regard
to the group of stakeholders being given the same rights and abilities for
the Mile 22 site.
BELIZE SOLID WASTE MANAGEMENT PROJECT

4.2.3.5.5 Post Construction Operations
The concern over ongoing operations is a valid concern that not only
relates to Mile 22, but to the development of any landfill. The best design
concepts will not work during the operational life unless the site operator is
committed to execute the plan both during the operating life and during the
post-completion period. This is still a major issue with the proposed
Regional Sanitary Landfill at Mile 22 site and in fact could be a larger risk
to have an operator allow operations to deteriorate due to the remote
location of the site. In addition the length of the access road could
encourage illegal dumping along the 3.8 kilometer route.
