<br /> Work zones will move as the debris is cleaned up from the streets and boulevards. When the work zone is
<br /> located on or near a heavily traveled roadway, it will require additional flag persons, additional signage,
<br /> and/or assistance from local law enforcement agencies. The crew foreman will monitor the work zone and
<br /> all other aspects of crew operation.
<br /> Hazardous Tree, Limb and Stump Removal
<br /> Ceres employs crews with professional tree climbers and aerial equipment such as bucket trucks to remove
<br /> hazardous hanging branches and leaning trees ("hangers" and "leaners"). Ceres has performed this work
<br /> on previous storms with an excellent safety record and with an excellent damage record. In response to
<br /> Hurricane Katrina, Ceres was responsible for trimming and removal of trees in all of Jefferson Parish, LA
<br /> amounting to 18,599 trees.
<br /> Flooding
<br /> Ceres expects flood recovery work when a client has significant land area in a 100-year flood zone, and
<br /> when rivers and other waterways pass through the area to be cleaned. Flood recovery work generally
<br /> requires specialty equipment, such as long-reach excavators, floating excavators, and a greater amount of
<br /> . tracked skidsteers. Wheel loaders with buckets and grapples are often used to remove debris that may fall
<br /> apart if picked up by a knuckleboom loader.
<br /> Ceres has surveyors and other specialists on staff ,,,.‘";N::;', {t . w ',-,
<br /> who can determine which flooded areas will be likely �4 S;I c Tt '- ,

<br /> structures. For example, in a post flood situation, a ��
<br /> house may have sheetrock walls that must be _ -- - • - -v-=j
<br /> inspected by an expert who determines that sheetrock Flood debris from the Spring 2008 Iowa Floods
<br /> must be removed. After removal, the debris may be left on the right-of-way in loose piles. These piles will
<br /> probably present more difficulty in loading than vegetative debris, or a pile of wind-blown privacy fence,
<br /> because the waterlogged debris may have no structural integrity and will fallinto.pieces when picked up.
<br /> For this reason the types of equipment may be different in flood situation, with wheel loaders and dump
<br /> trucks more prevalent and self-loading knucklebooms less prevalent than in a non-flood storm. Ceres owns
<br /> nearly all types of equipment used in flood recovery, and we have subcontractors who specialize in flood
<br /> disaster recovery.
<br /> Ceres has a special hazardous materials (HAZMAT) team that specializes in preventing the spread of
<br /> contamination and infestations of rodents in areas that were flooded. From past experience, Ceres knows
<br /> that these areas are prone to contamination from sewage, agricultural run-off, mold, and chemicals, they
<br /> are also prone to rodents. Ceres plans to concentrate heavily on these areas in order to limit the spread of
<br /> contaminants and to limit the breeding of rodents and pests. Once the determination is made in conjunction
<br /> with local officials and the EPA, if applicable, Ceres will utilize its special teams to target these areas.
<br /> Following Hurricane Katrina, for example, Ceres made weekly passes in some formerly flooded areas, and
<br /> "mirrored"or"paralleled"the municipal sanitary waste teams. By doing this, neighborhoods were kept clean
<br /> on a weekly basis so that pests could not be alternately supported by garbage and flood debris—instead
<br /> all potential habitat or food for pests was removed frequently to ensure a safe neighborhood.
<br /> Pathogens are also more of a problem in flooded areas.Water promotes growth of undesirable organisms,
<br /> and it also facilitates transfer of bacteria that exist in an environment to humans working in that environment.
<br /> Our corporate health policies address hazards of working in a flooded disaster environment, and Ceres
<br /> uses procedures including additional immunizations and additional personal protective equipment such as 0
