RECOMMENDATION
The Policy and Services Committee (Committee) and staff recommends that Council
approve the following:
1)Implementation of a single stream recycling program; Committee voted 2-1
recommending program;
2)Change the collection of yard trimmings to cart service; Committee voted 3-0
recommending program;
3)Supply optional curbside cart service for garbage; Committee voted 3-0
recommending program; and
4)Approve compressed natural gas as an alternative fuel for the collector’s
recycling collection vehicles. Committee voted 3-0 recommending pro~am.
COMMITTEE REVIEW AND RECOMMENDATIONS
On March 9, 2004 the Policy and Services Committee (Committee) discussed the
Proposed New Recycling and Solid Waste Services. (See Attachment 1: CMR 165:04).
The Committee voted two to one to accept staff’s recommendation to implement a single
stream recycling program with the condition that staff returns to Council with a status
report 18 months after the programs begin (scheduled to begin July 2005). Chair
Kishimoto voted "nay" because of her concern of where and how the recycled materials
would be used and the global view of how the single stream program would integrate
with the proposed Environmental Service Center project. The Committee voted
unanimously to accept staff’s three other recommendations, including changing the yard
trimmings recycling collection to cart service, supplying residents with the option to
CMR:205:04 Page 1 of 6
obtain a cart for curbside garbage service, and approving compressed natural gas as an
alternative fuel for the collector’s recycling collection vehicles.
The Committee’s review included discussions regarding recycling markets and the
quality of materials processed; the alternative service optiong including the split cart
system; the single stream recycling program connection with the proposed future
Environmental Services Center; the environmental impact of the recommended new
services; and the impact on the refuse rates.
Both chair Kishimoto and Vice Mayor Burch asked whether the single stream material
was being recycled. Staff has obtained a recycling guarantee from Waste Management,
investigated recycling markets, visited single stream processing facilities and researched
at what level recycling material degradation occurs if any. The following were staff
findings:
Recycling Guarantee
To ensure that the materials are reused and/or recycled with the existing source separated
program, the City currently requires:
~Monthly Recycling Reports" from PASCO that include tonnages marketed by
material type and revenues received from those materials.
Staff conducts a "PASCO Performance Audit" which includes reviewing selected
recycled materials and the markets used to ensure materials are recycled.
With the proposed single stream program, the following items will be required from
PASCO to ensure that the materials are reused and/or recycled:
A monthly recycling verification form will be required to be filled out by Waste
Management reporting all inbound, outbound tonnages by material types, residue
rates, and specify the brokers purchasing the recycling materials.
The processing facility will also ~Tice per year perform an analysis of the Palo Alto
stream which will indicate specific quantities of materials being processed just from
Palo Alto.
Staff will require annual letters from the brokers and material manufacturers that
purchase the recycled commodities from the single stream facilities stating that they
recycle the material and what it will be recycled into.
PASCO will be subject to stringent performance adjustments including the possibility
of termination of its Agreement with the City if it is determined that PASCO or the
processing facility has landfilled the recyclables collected.
CMR:205:04 Page 2 of 6
Staff will continue to ensure that selected recycled materials are reused or recycled as
part of the "PASCO Performance Audit."
Recycling Markets
Markets are important to follow to ensure that all the materials are reused and/or
recycled, and that the highest market values are received. Waste Management reports
that minimal market changes will occur by switching from a source separated program to
a single stream because the materials sorts remain similar. Waste Management is giving
the City a high market value for the materials collected during the pilot program which
staff believes will continue if the single stream program is approved. Waste Management
markets its materials from a regional approach, resulting in a higher market value for the
material and ensuring long-term market commitments.
During the pilot program, staff inquired and followed where the raw materials were sold
and received written verification that these materials were used as recycled materials.
The following is what can be expected if the single stream program is approved:
The Waste Management Castroville facility currently markets 75 percent of its
fiber/paper tonnage to Asia, mostly China. These plants make packaging material such
as cardboard and paperboard as well as new newsprint from the recycling material
received from Waste Management. The remaining 25 percent of paper is sold
domestically to SMURFIT, specifically its San Jose site that makes cereal boxes for
General Foods, or Weyerhaeuser, a plant that makes new cardboard. Half of the plastic
containers are marketed to domestic plants within the United States and 50 percent of the
plastics are marketed to Asia. The plastic containers are shredded and made into plastic
pellets that are reformed to create a variety of new products including new beverage
containers, new toys and new household items. Tin cans are sold to domestic markets
and converted to new containers. Aluminum cans are sold to Anheuser Busch within the
United States and made into new beverage containers. Scrap steel is also sold to
domestic markets to be melted and formed into new metal materials. The glass is
processed at a facility in Union City where the material is further sorted and marketed to
Gallo Wineries (to be used in wine bottles) and to aggregate manufacturers that use the
glass mixture in road projects.
The best recycling guarantee that a community can obtain is to collect materials that have
positive market values. At the same time, communities have to be willing to risk
accepting a material type in order to improve the recycling markets. As a result, Palo
Alto expanded the materials accepted in the current pilot program to include the addition
of #3- #7 plastics, plastic bags, and milk and juice cartons. Waste Management is
successfully marketing the #3 - #7 plastic containers and staff recommends keeping them
in the single stream program. However, during the pilot program staff discovered that
plastic bags and other film plastics have a poor or negative market value and create
CMR:205:04 Page 3 of 6
problems with the sorting equipment at the processing facilities. The markets for the
milk and juice cartons are also limited and at this time, the material is only accepted and
recycled in North Korea. Since staff has not received a guarantee that the brokers will
recycle these materials and not ultimately throw them out as residue, staff recommends
not extending the collection of these materials with the citywide single stream recycling
program. However, staff does recommend that these materials continue to be collected at
the Palo Alto Recycling Drop-off Center where both PASCO and City staff can better
control where and how these commodities are marketed. In addition, if the overseas
market stops accepting the milk and juice cartons, the materials can easily be removed
from the drop-off center as an acceptable item. If the materials were collected curbside,
it~vould entail the re-education of the community to no longer place the material in the
recycling containers.
Single Stream Processin~o Facilities
Recycling materials collected through the proposed single stream-recycling progam
would be taken to a regional processing facility located outside the city limits. Waste
Management has two regional processing facilities that could accept Palo Alto’s single
stream recycables. The Castroville processing facility is currently the preferred location
to take the materials if the program is approved. The Castroville facility began
processing single-stream in September 2002 and is currently processing single stream
recycling for the following cities: unincorporated areas of Monterey County, Seaside,
Marina, Pacific Grove, King City, Sand City, Del Ray Oaks, Pebble Beach, Carmel and
Hollister.
The second Waste Management single stream processing facility is the Davis Street
Transfer Station located in Oakland. The Davis Street processing facility location
processes single stream recycling materials for 11 cities, including Walnut Creek,
Lafayette, Orinda, Moraga, Danville, unincorporated areas of Alameda County, Albany,
Emeryville, Castro Valley, Ora Loma Sanitary District, and Oakland. This facility is
currently at capacity in handling single stream recyclable materials but plans are being
made to improve this facility in the near future, which would allow Palo Alto to take its
recyclable materials to this facility, if it proved beneficial.
The table below compares the type of material sorts that are accomplished at these single
stream processing facilities and the source-separated materials that are processed at the
City’s Recycling Center. The only difference is that office paper, currently collected
only from the commercial sector, would be collected and processed with the mixed paper.

Recycling Material De,oradation
When municipalities first started rolling out single stream pro~ams a few years ago, they
ran into issues with marketing some of the material, primarily the fiber/paper stream, due
to high contamination levels of glass, or not being able to successfully separate most of
the newspaper from mixed paper. As a result, the material was often down~aded into a
lower-quality end product.
Staff’s research has found that material degadation in single stream is becoming less of a
concern due to advancements in technology and changes in the sorting equipment.
Today, processing plants have better screening of materials than they did even one year
ago since technology continues to advance as the processing facilities update their
equipment. As an example, Waste Management invested over $1 million last year to
update the equipment at its Castroville facility and plans to implement up to another $1
million in improvements this year to its processing lines to make the sorting of materials
faster and cleaner. As a result, the Waste Management Castroville facility is able to sort
the various fibers (cardboard, newspaper, mixed paper). An example of the sorting
equipment improvements is that it is able to market its mixed paper as a #3 Fade, the
same as the mixed paper collected from the source separated progam in Palo Alto.
If degadation of recyclable materials does occur, it lowers the value of the materials and
means that the raw material is reused and/or recycled in a different form. De~adation
does not result in landfilling.
By switching to a single stream or split cart recycling progam, the City would see a
decline in what is received for recycling revenues by approximately $740,000 annually.
CMR:205:04 Page 5 of 6
Waste Management reports that this loss of recycling revenues has little to do with the
degadation of recyclable materials, but is the result of the cost for equipment and the
additional labor needed to sort these materials.
With regards to Chairperson Kishimoto’s other concern about how single stream is
integated with the proposed Environmental Service Center project, staff has developed
the single stream pro~am which is not dependent on the future of the ESC or vise versa.
The advantages and disadvantages of having an ESC locally will be discussed at a later
date.

Staff recommends implementing a single stream recycling program, chanNng the
collection of yard trimmings to a cart service, providing residents -with the option of a
curbside cart for garbage service and chan=m~g the co!lection contractor’s recyc!ing
vehicles to run on compressed natural gas as a preferable alternative Nel.
Single stream recycling-will enable all residents as well as businesses and multi-family
complexes to benefit from usin~ a wheeled cart for the r,.,’vclm_ and yard trimming
services. Single stream recycling allows for the expansion of accepted materials,
improves container mobiliW, and reduces noise and litter created from normal collection.
The wheeled cart for recycling and yard trimmings will increase participation due to its
convenience rand ulc easy pro~am g-a_de:mes containing less restrictions than the current
system. Alternatives considered to the single stream recycling included the split cart
system (where customers sort recycling materials into two compa-tments) and keeping
the existing four recycling crate system.
Staff also recormrnends providing residents with the option to obtain a wheeled cart,
collected at the curb. for their garbage service. This service would eiiminate residents’
concerns of missing lids and of containers purchased at local hardware stores not meeting
the required restrictions for garbage collection. The garbage cart would also eliminate
privacy concerns, as well as improve container mobility and minimize coilection cost.
Finally, staff recommends requi~mg the collection contractor to change the recycling
collection vehicles to run on compressed natural gas as a preferable alternative fuel that is
also approved by the Cali~%rnia Air Resources Board’s fiature clean air requirements.

Staff requests that the Policy and Services Com_mi~ee recommend to Council k~proval of
the following:
1)Implement a single stream recycling prog-ram.
2)Change the collection of yard trimmings to cart service.
3)Supply optiona! curbside cart service for garbage.
4)Approve compressed natural gas as an akemative fuel for the collector’s
recycling collection vehicles.
BACKGROUND
As required in the ageement with the Palo Alto Sankadon Company/%;aste Management
(PASCO), the City periodically performs a customer service satisfaction survey to
evaluate the general satisfaction of the community with the quality of service provided by
PASCO. The results from the survey conducted in 2001 showed that 96 percent of
residents responding to the survey rated the PASCO ser,4ce as excellent or satisfactory
(C’_M_TZ 364:0!). The survey also provided the opportunity for residents to add commen~s
about their service. Comments related to improving service levels included: 1) recycle
additiona! plastics._ . -~,v~ improve how ~’~o~ta~ne~- ~ ,’~ are ,-~*~,~,~ a~er being ~-"~’; ~’~ 3) reauce
collection noise, and 4) create flexibility and simpIi~ collection methods. As a result of
this survey., a pi!ot program was implemented to address the concerns and needs of the
public.
Currently residents have to separate curbside recycling materials into four different
stationary containers and then carry them to the curb for collection by PASCO. The new-
piloted service involved testin~ sin~!e~ stream ~e..’~clin_.~ , ~ ~ Sin_~le~ stream recvclin~ ~ is the
cow_mingled co!lection of recyclabte materials in one wheeled cart. The pilgt also tested
the placement of yard trimmings in a wheeled cart instead of the current system where
residents place their yard trimmings into their own 32-gallon cans, which are then carried
to the curb for collection.
The pilot prog-ram was implemented in October 2002 in five different locations
throughout the Paio Alto community, including sections of Downtown, Crescent Park,
M~d,own/V~,~s~ Bayshore Road area. Barron Park and College Terrace. The pilot
pro~am was comprised of approximately 2500 households, with about 500 being
serviced each day of the week. Each household in the pilot area received new pubiic
educational materials and was provided with two 96-gallon wheeled carts, one for the
commingling of r,.cy~I_n= materials and one ,_or yard trirnmin_c~s materials.
The 96-ga!lon cart s:ze was chosen because it would accommodate al! the _,~c~,c,able
materials placed inside the current system of four lg-gallon recycling crates. The cart
CMK:I65:0a Pa=.. of 1 t
also accommodates corrugated cardboard and extra materials generated seasonally
(mixed paper during the. holidays, e,-ctra beverage containers during the warm summer
days). Recycling materials accepted were expanded to include all plastics numbered one
through seven, milk and juice cartons, and plastic bags. The 96-gallon cart for yard
trimmings accommodates the normal amount of material placed for collection at the curb
as well as any extra yard trimmings occasionally generated by residents.
Staff evaluated carts from five different cart manufacturers and selected the cart delivered
to residents for its pricing, capacity to hold recycling materials, ease in maneuverability
and compatibility with the existing PASCO collection equipment. The color of the carts
was chosen after careful consideration .of the colors normally associated with recycling
materials and yard trimmings. For yard trimmings, the color geen was selected since it
is associated with the color of the materials collected. The blue coior for the recycling
cart was custom-made for the Ci~ of Pato Alto. The color blue is generally associated
with recycling of materials. Since Palo Alto prides itself in being unique and different
from other municipalities,, staff wanted to continue that tradition by having the
manufacturer create a custom blue color for the recycling cart.
The deliver of the carts and announcement of the pilot recycling progam was well
accepted, with the normal level of initial resistance to service changes. City and PASCO
staff worked hard to accommodate special requests and to educate the public that
residents would be ~ven the opportunity to evaluate the serv’ice and help determine
whether to continue and expand the piloted service cit?-~vide. Within a month, residents
initially rejecting the idea of change began to enjoy the benefits of single stream
recycling.
The recycling materials are collected at the curb and taken to a processing facility, where
both people and machinery with advanced technology separate the recyclable material.
The sorted materials are then marketed to material brokers or manufacturers, According
to PASCO’siWaste Management market analysts, the majority of the material including
paper is sold to markets in Asia. Some materials such as some plastic, tin and glass are
sold to markets within the United States.
DISCUSSION
A survey of the piloted area was conducted in March 2003 to assess residents’ response
to the new s:#stem of single stream recycling and yard trimmings using wheel carts. The
survey inciuded questions about their preference of container, the size of the carts issued
during the pilot, color of the Cart and collection changes noticed during the pilot. Staff
received !,279 responses for a 55 percent return rate. When asked the question, "Do you
prefer the cart instead of the crates?" 93 percent of the survey respondents preferred the
cart, with 4 percent disageeing with the statement. The survey responses also showed
that the size of the recycling cart issued at the beginning of the pilot was adequate for 59
percent of the participants, while 32 percent preferred a mid-size cart (64-gallon) and 7
percent preferred a smaller 32-gallon carE. For yard trimmings, 68 percent of the survey
CMR:165:04 Page 3 of l 1
participants preferred the larger 96-gallon container, while 25 percent preferred the
smaller containers. In the survey, 86 percent of the respondents liked the custom blue
color for the recycling carts, 4 percent did not like the color, and 9 percent had no
opinion. The survey results for the color of the yard trimmings cart were similar in that
85 percent liked the color, 1 percent did not like it and 9 percent did not have an opinion.
While some survey responses expressed the concern about the lack of sorting and a
change in their recycling habits, most residents welcomed the ease and convenience of
the single-sort system.
Single Stream Recvclin_~
Staff recommends expanding the piloted single stream recycling progam to the entire
city. Single stream recycling has many advantages. It saves people time from having to
sort recyclables into the current four-crate system and carry each material t.-v?ge to the
curb. Collection carts have aKached lids and wheels. This improves cart mobility and
reduces noise and li~er created from the collection progam. It al!ows the Recycling
Pro~am to expand the types of materials accepted. It changes the desig-n of the
collection trucks to single compartment bodies. This reduces the number of collection
vehicles needed to collect materials, reduces noise levels in neighborhoods, reduces street
wear, reduces collection cost and allows the ability to utilize full truck capacities. The
semi-automated collection of the cart instead of the current manual co!lection of crates
results in reduced worker injuries and in the future will reduce the collector’s insurance
costs.
Single stream recycling in wheeled carts has proven to be a successful sera, ice for the
Palo Alto residents participating in the pi!ot program. Single stream recycling is also a
service that has become the trend in many communities throughout the nation due to its
convenience to the customer and the technoto~cal improvements that have been made in
the sorting systems. City and PASCO staff believes that single stream recycling Will
increase participation and tonnage due to its convenience in using the wheeled cart and of
the easy progam guidelines containing less restrictions than the current system. Based
on the results from the piloted area, PASCO projects an increase of 10 percent in curbside
recycling tonnage and 35 percent increase in curbside yard trimmings tonnage if services
are expanded citywide to residents.
Collection Containers
With ~e expansion of single stream recycling cit;~dde, residents would be given the
choice of pre-selecting their recycling cart size (32, 64 & 96 gallon). The default cart
size for those residents that do not make a cart selection would be a 96-gallon cart. This
is based on the responses from the pilot survey where the majority, (59 percent) of
respondents preferred the larger 96-gallon cart for recyc!i_n_g. The carts used for single
stream recycling will alleviate some of the container placement issues mentioned in the
PASCO survey by reducing the number of containers placed at the curb for service.
Residents will be given the option to keep and reuse their existing crates or the crates w’ill
be collected and recyclect.
CMR: 165:04 Page 4 of 11
Processing
The goal for the City’s solid waste management services is to have Palo Alto’s materials
se~dced within the community instead of having to transport materials to other
jurisdictions. However, the current Palo Alto Recycling Center is not equipped nor does
it have the space to process the commingled mixture of recyclabtes. With single stream
recycling, PASCO would transport the material to another Waste Management materials
recovery facility for processing. The proposed processing facilities are the Davis Street
Transfer Station located in Oakland or the Waste Management Castroville Processing
Center via the transfer station in San Jose. The additional travel time to deliver the
recycling materials to Oakland or Castroville would offset any time saved during the
collection time. Since all the recycling is placed in one container, there is an increase in
processing costs and degadation to some of the marketable items. This resuks in
PASCO receiving a lower cost per ton for the materials marketed. PASCO currently
receives approximately $71 per ton for an average of 14,500 tons of material recycled
armually. PASCO projects to recei~,~e only $15 to $20 per ton for the single stream
material, resulting in a loss of revenue of approximately $740,000 on an annual basis. It
is estimated that the increase in participation wi!! !ead to an additional 1,450 tons of
materials to be recycled, which will offset some of the revenue loss by approximately
$30,000.
Single stream may also increase the amount of residue, which PASCO estimates to be
between 3 and 12 percent. The residue is a result of people placing items inside the
container that are not recyclabte. Staff plans to try to control the residue rate by
providing extensive educational outreach on what can be recycled. PASCO will also use
its non-collection notices to inform customers of items which are not recyclable. As a
way to prevent high levels of residue, staff recommends not extending the piloted
curbside collection of milk and juice cartons or plastic bags due to the poor plastic
recycling markets and the inability of processors to guarantee that all materials will be
recycled and not disposed as residue at the end of the sorting process.
As a result of sending the recycling materials to another community for processing,
PASCO would no longer operate the processing of recyclables at the local. Recycling
Center. The public drop-off center would remain open and would continue to accept all
the current recycling items including those not collected curbside such as milk and juice
cartons, polystyrene, and plastic bags.
Expandin_~ Recvclina for Multi-Family Complexes. Businesses and Schools
Staff recommends extending the single stream progam to multi-family complexes,
businesses and schools. The current service involves the collection of materials separated
in muttiple containers including: 1) office pak (a mixture of white and mixed paper), 2)
newspapers, 3) bottles and cans, and 4) cardboard. Allowing these sectors to mix paper,
bottles and cans would increase participation and tonnage due to the convenience and less
restrictive recycling guidelines involved in single stream recycling. Since the majority of
CMR:!65:04 Page 5 of I 1
cardboard from these sectors is oversized and is best placed in large containers, staff
recommends continuing the current cardboard service.
The change in service would involve collecting the existing carts and exchang-ing them
for the new single stream recycling carts that would resemble those issued to residents.
Al! recycling carts would then be standardized (by color, size and manufacturer) through-
out the city and Could be ser~dced by any of the collection trucks.
Carts for Yard Trimminas Collection
Staff recommends changing the collection of yard trimmings to cart service. Collecting
yard trimmings in wheeled carts means that the cart would be more convenient and easier
to wheel to the curb than carrying multiple 32-gal!on cans full of yard trimmings. The
carts would provide a clean and uniform appearance, as well as improve the aesthetics of
the streets on collection days due to the containment of the yard trimmings. PASCO
would create desig-nated routes for the collection of yard trimmings, resulting in more
efficient use of the truck space and fewer trips to the composting site at the landfill.
Under this progam, residents would be given-the option of obtaining one 96-gallon cart
at no charge. The 96-gallon cart would accom_m__odate the same amount of ma*,eria! as
three of the currently allowed 32-gallon cans. Smaller sized carts (32 and 64-gallon)
would also be available. Residents regularly generating more yard trirmrnings and
needing more than one cart would have the option of renting or purchasing additional
carts.
The processing of the yard trimmings would continue to occur at the composting site in
the City’s landfill.
Optional Curbside Cart Ser~,ice For Oarba_~e
Staff recommends continuing the backyard garbage collection se~’ice, in addition to
offering residents a choice of obtaining a wheeled cart and placing it at the curb for their
garbage collection. PASCO currently provides backvard garbage collection to residents
with can service. This allows residents to leave the cans in a convenient location on their
private property and for a PASCO driver to enter the backyard to empty the containers on
collection day Over the years, staff has obtained feedback from residents *hat 32-gallon
cans are becoming more difficult to obtain through the local hardware stores. The
containers sold are generally larger and over the size limit required for garbage service.
..~,,s~d,,nts are also not compatible with theMany of these new containers ~urchased by ~ " ~ ’
PASCO equipment. By having PASCO provide the optional wheeled cart for garbage, it
ensures that the cart will be compatible with the collection equipment used and the
weight limit guidelines. The cart service would also eliminate some of the concerns
residents mentioned in a recent PASCO customer service survey of lids not beino
returned to the container, which is a problem thatrises during rainy and windy days.
With this option, residents would be provided a wheeled cart. at no cost for the collection
of their garbage. Those residents wanting a cart for their garbage would be provided the
CMR:165:04 Page 6 of 11
choice of cart sizes that would equal the current service rate structure. The smallest size
available is a 20-gallon, which is the same capacity as the mini can currently used by
some residents. This cart would be a 32-ga!lon cart with a 20-gallon insert allowing only
20 gallons of trash to be piaced inside the cart. Other cart sizes would include 32-gallon,
64-gallon and 96-gallon. The 96-gal!on would be equivalent to the current three cans
(each at 32-gallons) used by some residents.
By choosing the cart option for garbage collection, residents would be required to place
their carts at curbside for collection. Curbside collection would help maintain the cost of
proYiding the cart collection service by allowing PASCO to maintain its efficiency in
emptying the carts. Similar to the recycling carts, by placing the garbage carts at the
curb, PASCO would be able to drive up to the carts. The driver would place the cart on a
liRing mechanism, which would then empty the cart without moving it far from its
original location.
No rate incentive was proposed to residents who elect to put their own carts at curbside
because the collection labor saved would be used towards the CiD" yard trimming
collection pro~am~ in anticipation c~f the
pro~am.
Education
PASCO would need to hire three additional temporary customer service representatives
for approximately six months prior and during the start-up of the new services to handle
the expected increase in customer telephone calls and administrative work,
s~a~ will develop all the educational outreach mat~na~s to educate the Palo Alto
community, including residents, businesses and schools, on the future service changes.
This will include developing a postcard to send residents requesting that they pre-select
the size of their recycling and yard trimmings cart as well as offering the option of a
garbage cart for curbside collection. Brochures with new recycling ~m.!idelines will be
developed and distributed to all customers. Newspaper advertisements will be placed in
the local newspapers. In addition, staff will work with business, home and neighborhood
associations as well as the local media to inform the community about changes to their
seEr-ices.
Collection Vehicles & Alternative Fuels
Staff recommends switching the new PASCO recycling collection vehicles to compressed
natural gas (CNG).
The City requested that PASCO research the possibility of using alternative fuels to
improve air quality and to comply with upcoming mandates by the California Air
Resources Board (CARB). PASCO switched to using biodiesel (B-20) as a fuel
alternative in i[s vehicles in July 2002, helping to reduce air emissions during collection.
CMR:t65:04 Page 7 of il
However, it is uncertain at this tim_e if using B-20 would meet future requirements by the
Air pollution reductions can be made by switching the vehicles to operate on another
preferable alternative f~,~el such as CNG. Since four of the PASCO recycling trucks are
due for replacement during FY 2004-05 and two vehicles are scheduled for replacement
the following fiscal year, the City and PASCO have an opportunity to obtain trucks that
operate on CNG to meet the CARB requirements. Each collection vehicle with the CNO
fuel en~ne would cost an addkional $50,000. The added cost would be included in the
FY 2004-05 budgeted PASCO depreciation costs. PASCO plans to fuel these vehicles at
the Ciu;’s new CNG fueling station. The City’s Public Works Department?Refuse Fund
would absorb the cost of the fuel (see Attachment A). Using CNG would require PASCO
to retrofit its maintenance shop at a cost of approximately $100,000, bud=eLed through
the PASCO budget. The retrofit includes installing gas detectors; required ventilation,
and spark prevention improvements as wel! as upgadLng the shop’s heating and electrical
s~,stem, Maintenance and labor costs associated with CNG are estimated to increase
approx_imatety 15 percent, which would also .be budgeted through the normal PASCO
budget process.
Alternative h Split Cart System
As an alternative to single stream recycling, staff considered the split cart system.
Instead of commingling all of the recvclables into one wheeled cart as the case of the
single stream recycling, residents would sort their materials into two-categories. Paper
(mixed paper, newspaper and smal!er pieces of cardboard) would be placed in one side of
the cart and the rest of the accepted materials (glass, plastic boKles, and cans) would go in
the second partition of the cart. The t-y.?e of materials accepted would aiso be expanded
to include all plastics numbered 3 through 7.
This progam woutd be similar to the direction that the cities of Sunnyvale and Mountain
View are taking their recycling progams, and it would allow- the City to take the
materials from the split cart to the SMART Station in Sunnyvale for processing. The
SMART Station is currently processing materials from the split cart service used in the
City of Sunnvvate and is gearing up to take the recycling materials from Mountain View.
The potentia! for PASCO to reduce employee injuries and worker’s insurance costs
would also be realized since the semi-automated lifting of the carts would be used instead
of the crates that are cu~ently collected manually.
W2hile the split cart would be an improvement over the current four-crate system, and
residents could save time in separating recyclable materials and the labor from carrying
the various crates to the curb. there are a number of disadvantages.
Costs for the divided cans are 93 percent more than the cans for single stream recycling
(see At~achmen.t A). There are more components to a split cart, increasing the potential
of having a higher rate of repair and maintenance costs. The spilt cart can lead to the
CMR:165:04 Pa~,o 8 of I I
contamination of the mate~als when residents run out of space on one side of the cart and
use the available space on the other side of the cart partition. This contamination would
also lead to a higher amount of residue. The split cart would require trucks with a split
body, which may affect the collection efficiency since if one side of the truck fills up
faster than the other, the PASCO driver might have to make an extra trip to the SMART
Station to unload, the truck before continuing to finish the route.
With the split cart option, residents would be given the opportunity to pre-select the size
of their cart; however, the options would be either a 64-gallon or a 96-gallon cart with a
divider in the midd!e of the cart. Due to the nature of the divided cart, the 64-gallon cart
is the smallest size available. Unfortunately, this size would be too large for some
residents in Pa!o Alto.
With the split car~ system, PASCO would stiI1 need to hire tN-ee additional temporary
customer service representatives for approximately six months prior and during the start-
up of the new services to handle the expected increase in customer telephone calls and
administrative work. City staff would develop the same educational outreach materials
as single stream recycling to educate the Pa!o A!to community, including residents,
businesses and schools, on the serv’ice changes.
Alternative II: Continuing with E?dsting Four Recycling Crates
The second alternative to single stream recycling would be to continue with the e~sting
four-crate system. This option involves expanding the type of mate~als accepted for
curbside collection and requesting that residents keep their existing four recycling crates.
Residents would continue to sort their recycling materials into the four crates separating
mixed paper, newspaper, plastic containers, glass bogles and cans. Cardboard would
continue to have .to be flattened, folded to the required size and placed next to the
recycling crates. City staff would p~iepare outreach materials to educate the community
on the expanded list of accepted plastics and residents would be able to add them to their
existing crates. ~amy overflow of materials would be accommodated in a paper bag
placed next to the crate at the curb.
Keeping the e.’dsting crate system means residents will continue to have to sort their
materials into the four individua! containers and will need to adhere to the current sorting
restrictions. Since the crate system began in 1994, many of the existing crates are due for
replacement at an estimated cost of $3 84,000 including the cost to collect the old crates to
be recycled. (See Attachment A).
This option would not have a si~m~_ificant impact on the PASCO operation or processing.
The processing and marketing of the recycling materials would continue to be done at the
Palo Alto Recycling Center with minimum impacts to the operation.

Implementation Timeline of New Services
The projected implementation date for the new services is July t, 2005. This is based on
having approximately one year from the time Counci! approves the implementation of the
new services and the new budget. This would provide the City and PASCO time to 1)
order the new collection vehicles, 2) order and assemble the carts, 3) create, print and
distribute educational outreach materials, 4) train emp!oyees on the new progam
collection and guidelines, and 5) inform the community of the future services and provide
them with information and time to choose the size of their carts.
RESOURCE IMPACT
Funds to implement the new pro~ams are detailed in "Attachment A". One time
expenses include educational materials & order forms ($40,000), cart purchases,
assembly and delivery ($2,007,300), crate collection and recycling ($16,000), temporary
help for outreacN;education ($23,550), and CNG shop conversion ($100,000), totaling
$2,186,850.
Fiscal year 2004-05 adopted-in-concept budget included a 10 percent rate increase for the
Refuse Fund to maintain the Cnuncil-actnnt~d minimum Rnr~ <1~,;t~-,o,;~,,, ,,,~,o ....
(RSR). If the 10 percent rate increase adopted-in-concept for FY 2004-05 is approved
and the recommended staff pro~ams go forward, no additional rate increases will be
needed in FY 2004-05. There will not be any rate reductions in future years if the
recommended pro~am.s do not go fopa, ard, however rate increases could potentially be
delayed one fiscal year if the new progams are not approved. Staff identified two (2)
one-time reductions in the Refuse Fund operating budget, $1.275 million in the
Environmental Services Center - Capital Improvement Project and $585,943 from the
adopted-in-concept FY 2004-05 payments to PASCO, as a result of PASCO being more
than 2% outside the/target operating ratio range in FY 2002-03. These reductions will
provide the majority of the one time funding for the capital costs of the new pr.ogams
with remaining amount funded by the RSR.
The on-going costs for the proposed new progams are anticipated to be $659,414 in FY
2005-06 and $630.944 in FY 2006-07 and each fol!owing fisca! year, mostly due to the
anticipated loss of revenue ($740,000), from the sale of recyclabte materials. These on-
going costs have a rate impact calculated at nearly 3% of the revenue requirements for
the refuse fund.
ENVIRONMENTAL REVIEW
This project is a class 8 categorical exemption from the California Environmental Quality
Act under Section 15308 - action by regulatorT agencies for the protection of the
enviro_n_ment.
POLICY IMPLICATIONS
The implementation of the new serwices would temporarily be in conflict with the City’s
Comprehensive Plan N-55, which requires the City to ~’Maintain and expand the use of
CMR:I65:04 Page 10 of ll
the Recycling Center at the City’s refuse disposal area". However, the implementation of
the Environmental Services Center full size proposal would provide single stream
processing and would make the new services consistent with the Comprehensive Plan.
