COMPOST EQUIPMENT EVALUATION
- EXECUTIVE SUMMARY The City of Lock Haven (Lock Haven) currently delivers leaves to a 2-3 acre Permit-By-Rule
compost facility located at the City’s Waste Water Treatment Facility. Brush is taken to the
Clinton County Solid Waste Authority located in McElhattan less than five miles away. With
recent additions of spring and fall yard waste collections and other improvements to the leaf
waste collection program, Lock Haven has taken steps to ensure its leaf waste collection program
complies with Act 101 and applicable PADEP guidelines. With additional collections and
increased program awareness, the volume of leaves and other yard wastes generated by Lock
Haven will increase, and will require processing.
Lock Haven proposed a Wildcat TS-514
windrow turner and a Case 621D wheel loader in a recently approved Section 902 Recycling
Grant. In this evaluation, GF provided technical guidance to Lock Haven in the final selection
of suitable leaf windrow turning equipment to support a sustainable compost operation. As a
baseline, it is understood that the proposed equipment will be dedicated to the compost facility
and that Lock Haven will expand their composting efforts in the near future, possibly to include
a new site and participation by one or more other municipalities.
Based on our equipment evaluation GF recommends Lock Haven procure the following:
Wildcat TS 514 – Windrow Turner - $92,900 (as quoted to Lock Haven)
Case 721E – Wheel Loader/quick coupler/3.5 cubic yard bucket - $135,000 (verbal quote from
Groff Tractor)
Although GF did not complete a leaf waste collection program analysis or a compost site
evaluation during this study, we obtained background information on these programs from Lock
Haven. Based on our experience with leaf waste collection, compost operations, and based on
information reviewed during this evaluation, GF recommends Lock Haven (refer to Section 9.0
for more detailed recommendations):
Prohibit the use and delivery of plastic bags to Lock Haven’s leaf waste collection program.
Use the calculations provided in this Report to more accurately estimate leaf quantities and to
help estimate the windrows’ site and land area requirements.
Dump loads of leaves in rows/windrows on site as they are delivered, not in piles to be
reconfigured later.
Turn leaf windrows with the TS-514 approximately once per week in the first month after
delivery and then 1-2 times per month for the following 5-7 months. Cure leaf compost for
two months before distribution.
At least one of the Lock Haven compost facility staff should be certified in composting
through the Professional Recyclers of PA (PROP) compost courses or similar composting
course to understand the compost process and operation.

City of Lock Haven – SWANA Recycling Technical Assistance____________________________________________March 2008
Conduct routine site maintenance/repair around the windows to prevent rutting. It is
recommended Lock Haven pave the area used for active windrow composting if a new,
larger compost site is located and operated.
Identify one or more suitable regional compost sites in the next 12-18 months that has up to
five (5) acres for active composting and 2-5 additional acres for curing, traffic ingress/egress,
equipment storage, finished material loading, and future expansion.
Continue a positive, ongoing relationship with the Clinton County Solid Waste Authority to
serve as a processor for yard waste and to use as a resource for equipment (i.e. grinder and
trommel screen).
In the future, Lock Haven should sell finished compost and mulch and also charge tip fees
for incoming loads if commercial vendors deliver to the site.
When Lock Haven has a comfortable handle on operating the compost facility, it could
identify vendors (e.g. landscapers) that can deliver truckloads of grass on a
scheduled/managed basis to accelerate the compost process and to improve the compost
product quality.
Submit for reimbursement through the Act 101, Section 902 Recycling Grant for any
additional eligible recycling program and compost costs, including the outstanding cost
balance for the recommended Case 721E, which is roughly $40,000 more than the proposed
Case 621D.

INTRODUCTION
This Report summarizes a study conducted by Gannett Fleming, Inc. (GF) for the City of Lock
Haven (Lock Haven), Clinton County, Pennsylvania. This study and evaluation was completed
for Lock Haven as part of the Recycling Technical Assistance Program sponsored by the
Pennsylvania Department of Environmental Protection (PADEP) and the Solid Waste
Association of North America (SWANA). During this study, GF provided the following:
2.0
Reviewed the specifications and suitability of the compost equipment proposed in Lock
Haven’s most recent Act 101, Section 902 Recycling Grant;
Verified calculations of incoming leaf waste quantities;
Estimated compost site area requirements for windrows;
Contacted equipment vendors and compost facility operators to obtain information about
various windrow equipment operation and effectiveness;
Provided recommendations related to leaf windrow turning equipment and wheel loaders
for pulling the windrow turner, and;
Completed this report to summarize and document our findings and recommendations.
STUDY BACKGROUND
The City of Lock Haven is the largest municipality located in Clinton County, Pennsylvania.
The City is home to roughly 9,149 residents (2000 US Census Bureau) and encompasses
2.3 square miles. Lock Haven is “mandated” by the Municipal Waste Planning, Recycling and
Waste Reduction Act of 1988 (Act 101) to provide curbside recycling services, including the
curbside collection of leaf waste. Leaf waste, as defined by Act 101, includes leaves, garden
residues, shrubbery and tree trimmings, and similar material, but not including grass
clippings.
In 2007, PADEP notified Lock Haven that they should implement a collection and processing
program for leaf and yard waste that meets Act 101 requirements and PADEP policies and
guidelines. In order to properly manage their leaf waste, Lock Haven successfully submitted an
application for a Permit-by-Rule compost facility. Yard waste pickups were also added to the
curbside program. Brush is taken to the nearby Wayne Township Landfill operated by the
Clinton County Solid Waste Authority. This evaluation is to assist Lock Haven in selecting
appropriate leaf windrow turning equipment, which will facilitate compliance with applicable
leaf waste management regulations and help Lock Haven operate an efficient, sustainable
composting program that will benefit the local community.

PENNSYLVANIA ACT 101 LEAF WASTE REQUIREMENTS
It is important to understand the requirements that govern the methods and frequency by which
leaf waste must be collected and managed by Lock Haven to be in compliance with Act 101.
Collection frequency impacts the incoming material quantities, which in turn affects the
processing and equipment needs. The following guidance information was prepared by PADEP
in May, 2007 to help Act 101 mandated municipalities like Lock Haven to better understand and
meet their requirements for managing leaf waste. Lock Haven will need to implement a leaf
waste management program consistent with these regulatory requirements. With the recent
addition of spring and fall yard waste collection, and as supplemented by the Clinton County
drop-off location, Lock Haven’s leaf waste program appears to comply with the regulations.
Act 101, Section 1501(c)(1)(ii) and (iii), requires residents in mandated municipalities to
separate leaf waste from other municipal waste generated at residential, commercial, municipal
and institutional establishments. “Leaf waste” is defined in the Act as “Leaves, garden residues,
shrubbery and tree trimmings, and similar material, but not including grass clippings.” Sourceseparated leaf waste, as with other recyclable material, is required to be collected at least once
per month as set forth in Act 101 Section 1501(c)(2) and (3) and processed at PADEP-approved
composting facilities.
Municipalities that are mandated to comply with Act 101 which have programs that collect
leaves only in the fall are not in compliance with the Act. In order for municipalities that are
mandated to comply with Act 101 to have a leaf waste collection program that meets the
minimum requirements, the program must, as a minimum:
1. Require by ordinance that leaf waste consisting of leaves, garden residues, shrubbery and
tree trimmings, and other similar material are targeted for collection from residences and
commercial, municipal and institutional establishments; and
2. Establish a scheduled day, at least once per month, when leaf waste is collected from
residences; or
3. Establish a scheduled day, not less than twice per year and preferably in the spring and
fall, when leaf waste is collected from residences, and facilitate a drop-off location or
other collection alternative approved by PADEP that allows residents in the municipality
to deposit leaf waste for the purposes of composting or mulching at least once per month.
The leaf waste drop-off location may be located in a neighboring municipality or at a
private sector establishment, provided that an agreement is in place to utilize that location
and the municipality keeps residents and commercial, municipal and institutional
establishments informed of the option at least once every six months.
4. Ensure that commercial, institutional and municipal establishments generating leaf waste
have collection service.
5. Municipalities are encouraged to manage source separated Christmas trees as leaf waste
for processing at PADEP-approved composting facilities.

INCOMING LEAVES AND YARD WASTE VOLUME
Leaf collection is provided by Lock Haven’s Public Works crews in October and November,
with the actual collection periods being affected by the weather conditions in a given year. In
2007, due to extended warm temperatures, many municipalities found themselves collecting
leaves much later in the season than is typical.
The total estimated quantity of leaves and yard waste collected for recycling in calendar years
2006 and 2007 are shown below. These figures were corrected by GF after it was noted that the
leaf box capacity used in the original estimates (5.5 cubic yards) was incorrect. In 2006, there
were 117 loads of vacuumed leaves and no brush/yard waste was collected. In 2007, there were
a total of 141 loads of leaves collected with 68 of these loads being leaves collected in plastic
bags. In the spring of 2007, 1.46 tons of brush/yard waste collected. Leaf quantities were
estimated using 400 lbs. per cubic yard for vacuumed, slightly compacted leaves. Truck volume
was estimated at 13 cubic yards at a 75% fill rate (or approximately 10 cubic yards) which
equates to 4,000 lbs. per truck load, using the same pounds per cubic yard as vacuumed leaves.
Tons were then calculated by multiplying 4,000 lbs. per truckload by the total number of loads
and then dividing by 2000. There were roughly 234 tons of leaves collected in 2006 and
282 tons of leaves collected in 2007. All bagged material was emptied at the compost site.

CITY OF LOCK HAVEN COMPOST OPERATION
At this time, Lock Haven’s compost operation will be primarily for the purpose of
processing/composting leaves that are collected by Lock Haven’s Public Works crews. Brush
collected by Lock Haven can, and is, taken to the Wayne Township Landfill for processing into
mulch. The landfill compost site can also be used for residential yard waste drop-off (see
Section 5.0).

5.1
Temporary Compost Facility at the Waste Water Treatment Plant
Currently, the Lock Haven compost operation is located at the Waste Water Treatment Plant
(WWTP). The 2-3 acre site is operated under the PADEP Permit-By-Rule compost guidelines
for yard waste compost facilities less than five acres in area. The guidelines establish siting
criteria, compost methods and requirements, and require the facility to meet a maximum material
loading rate of 3,000 cubic yards per acre for the active composting area.
In 2006 and 2007, leaves were unloaded on the 2-3 acres of unpaved composting area. It is
envisioned that the WWTP compost site will be temporary, used only to meet current disposal
needs and regulatory requirements for managing leaf waste. In the next two to three years, Lock
Haven anticipates identifying a larger compost site that will be suitable for serving the Lock
Haven’s processing needs for leaves as well as meeting the leaf processing needs of several other
local municipalities. Lock Haven is planning for a more economically sustainable program
through cooperation with other municipalities, which will increase material volumes processed
and ultimately result in revenue from Leaf Waste disposal fees and the sale of finished compost.
Based on GF’s experience with municipal compost facilities, the current 3-acre WWTP compost
facility is too small to effectively meet the demands for processing leaf waste as part of a
comprehensive and long-term facility for composting. However, three acres is adequate for a
shorter term option for composting leaves at current volumes, particularly if windrows are turned
frequently to accelerate composting, the compost quality is maintained, and material does not
accumulate on site from one year to the next year. Additional information and calculations on
windrows and facility sizing are in the following section.
In the future, if Lock Haven decides to apply for a General Permit (GP) under the current general
permit for a compost site over 5 acres, the application fee is $500, presently.
5.2
Sizing the Compost Facility Based on Incoming Volumes and Equipment
When the fall leaf collection period is completed, space will be taken up by windrowed leaves
before they settle and begin to decompose. The initial area needed will be determined by how
many leaves are collected, how densely they are packed, and how the windrows are constructed
and configured. Lock Haven placed an estimated total 2,580 cubic yards (~516 tons) of leaves at
the WWTP site in 2006 and 2007. When Lock Haven begins to utilize a windrow turner, the size
reduction of windrows can be accelerated, and as the composting process advances, combining
piles may be necessary to maintain an optimum windrow size. Combining piles can reduce the
land area used by windrows but this does not affect the initial amount of space needed to
accommodate leaves unloaded as received at the site.
GF completed some preliminary calculations to give Lock Haven an idea of how many cubic
yards of leaves are contained in a windrow and how much space is required for windrows
appropriately constructed for processing by a windrow turner. These calculations are for
estimating purposes only and can be greatly influenced by the density of the leaves, which is
highly variable. Additionally, the accuracy of the data for incoming truckloads of leaves will
directly impact the estimates. In this analysis, GF has not anticipated or calculated the necessary

size of a compost facility operated by Lock Haven that would receive material from other
municipalities as part of a regionalized effort.
The quantity of material that can be placed on one acre will correlate to the dimensions of the
windrows that are constructed. The dimensions of the windrows are limited by the type of
equipment that is available for turning the windrows. As a result of our investigation into the
most appropriate equipment for Lock Haven, GF has selected windows sized and configured for
turning by the Wildcat TS 514. Windrows will be constructed in pairs as shown below. For this
example, windrows configured in pairs for the TS 514 would have the following dimensions:
W = 14’ H = 5’ L = 160’. Assuming one acre is approximately 220’ x 220’ and the 30’
turning radius on each side reduces the distance on two sides a total of 60’, a windrow fitting on
one acre using the TS 514 will be 160’ long.
GF used the area formula for windrows that is recommended by the PADEP: Area (A) = .67 x
Width (W) x Height (H). The cubic yards can then be calculated by dividing (A) by 27 or A/27.
Using the above configuration, there would be approximately 280 cubic yards in every 160’
windrow. Configured in pairs with 4’ between pairs and 12’ between sets of pairs, 4-5 windrows
can be constructed which equates to 1,120 cubic yards to 1,400 cubic yards on one acre. It is
recommended that Lock Haven maximize the length of the windrow construction beyond 160’ to
the extent feasible to increase the total amount of windrowed material per acre and to increase
the efficiency of turning the windrows and operating the compost site. In 2007, the 1,410 cubic
yards of leaves collected by Lock Haven would cover about one acre windrowed in pairs. If 2006
and 2007 leaves remain, 1.5 – 2.0 acres for active composting should be adequate. Since leaf
collection and composting are in the early stages of promotion by Lock Haven, it is expected
incoming material will increase.

Clearly, any standard windrow configuration at Lock Haven’s compost site will not exceed the
permitted loading rate of 3,000 cubic yards per acre. However, Lock Haven must pursue
removing accumulated piles of compost or ground yard waste located in the active composting
area of the compost site on an annual basis. Otherwise annual carry-over could lead to
accumulated piles that exceed loading requirements. PADEP has historically been lenient
concerning loading rate maximums provided the compost facility is being operated satisfactorily.

CLINTON COUNTY SOLID WASTE AUTHORITY
Lock Haven is located less than five miles from the Wayne Township Landfill that is operated by
the Clinton County Solid Waste Authority (Authority) in McElhattan, Pennsylvania. The
Authority accepts brush and yard waste, pallets, and other wood material. There is no charge for
dropping off clean loads of brush and yard waste. The Authority will not accept bagged leaf
waste. Grass is not accepted. The Authority owns a Morbark Model 1300 Tub Grinder and
Morbark Trommel Screen, which are used to process the wood material into landscape mulch.
Mulch is sold to residents as follows:
Natural mulch: $13-14/Cubic Yard
Colored mulch: $22/Cubic Yard
The Authority has worked with Lock Haven to address their yard waste processing needs in the
past and will continue to assist Lock Haven as feasible. Processing equipment is available for
rent by Lock Haven to grind wood waste and screen material. The Authority has said it is willing
to assist with grinding woody material one day each year at no cost.

WINDROW EQUIPMENT EVALUATION
As included in the Act 101, Section 902 Grant Application, the City of Lock Haven proposed the
following pieces of equipment for its compost program:
Wildcat TS 514: Windrow Turner - $92,900
Case 621D: Wheel Loader - $96,333
GF conducted an evaluation of the proposed equipment items by contacting equipment vendors,
reviewing comparable compost equipment, and through contacting several compost facilities in
Pennsylvania. Equipment specifications gathered during this research are attached for reference
in Appendix A. Since the initial capital cost for the recycling equipment is 90 percent
reimbursable through the Act 101, Section 902 Recycling Grant program, and because Lock
Haven has been awarded funding, GF focused the analysis on operating costs and equipment
operating efficiency. Up-front capital costs are not a primary factor in this life cycle cost
analysis. Lock Haven will be impacted by the ongoing utilization, costs and performance of the
selected equipment.
Knowing the total amount of the grant award, GF did not review windrow equipment that greatly
exceeded the price range of the grant amount. Closed-cab drive-type windrow composting
machines like models available by Scarab and Frontier were not reviewed due to the approximate

City of Lock Haven – SWANA Recycling Technical Assistance____________________________________________March 2008
cost of this equipment being in excess of $300,000. These drive-type windrow turners are not
practical for the small quantity of leaves that require processing at the Lock Haven compost site,
even for the foreseeable future. GF also made the determination to limit the evaluation to
windrow turners that can turn piles a minimum of five feet in height. It is not recommended to
manage leaf waste windrows below much less than 5 feet in height because: 1) it is difficult to
maintain temperatures high enough to optimize the compost process in smaller windrows; and
2) the height of the windrow has a significant impact on the total windrow/material volume on a
given footprint, thus smaller windrows will not optimize the use of space on the compost site.
Although there are many operating factors, some of the key considerations for this compost
equipment analysis included:
Windrow Turners
- Total annual operating costs (labor, fuel, parts and maintenance)
- Throughput or processing capacity – cubic yards per hour (turning)
- Equipment impact on windrow configuration/site space utilization
- Overall equipment efficiency
Wheel Loaders
- Total annual operating and maintenance costs
- Bucket capacity
- Overall equipment efficiency
- Equipment versatility

7.1
Windrow Equipment Comparison Summary
The Wildcat TS 514 proposed for use by Lock Haven is a proven piece of equipment that has
been successfully operated on yard waste compost sites in Pennsylvania and in many other
states. The compost industry has increased production of single-pass straddle type turners over
the last 10 years because of their operational efficiency. The Wildcat TS 514 is a highhorsepower machine that partially offsets some annual operating costs (compared with other
turning equipment), like higher fuel consumption, by its ability to move through windrowed
organics quickly and efficiently. Turning efficiency of this machine is particularly noticeable in
the first pass when unturned windrows require the most energy to mix. Labor time can also be
saved when compared with some other windrow turners because the TS 514 maintains
consistently shaped windrows during turning, which reduces the amount of additional labor and
operational expense for rebuilding windrows with a loader. The windrows formed by the TS 514
(5’H x 14’W) are suitably sized to maintain heat and active composting. This turner also
optimizes space utilization of the compost site because it turns windrows in pairs or sets that are
close together (refer to windrow schematic in Section 5.2), reducing waste aisle space.
The exception to the Wildcat TS 514 being the most efficient unit is the gas consumption per
operating hour, which is higher than some similar equipment options. Overall the Wildcat
TS 514 is quality piece of equipment that will efficiently process windrowed leaf and yard waste.
With initial capital costs paid up front, the TS 514 has the greatest potential of the equipment
reviewed (those shown and some not reviewed in detail in this Report) to be a long-lasting
efficient straddle-type windrow turner that will minimize the amount of staff time spent turning
windrows.
General Comments: All of the turning equipment reviewed was capable of creating quality
compost assuming adequate feed stock and pile management. Vermeer is in the process of
buying Wildcat.
7.2
Optimizing the Use of the Wildcat TS 514
The Wildcat TS 514 can turn a 200’ leaf windrow in under 10 minutes. Optimizing the
processing potential of the high-capacity Wildcat TS 514 will require the City of Lock Haven to
increase the volume of material handled. At current volumes of Lock Haven leaves that require
processing, Lock Haven will not be able to utilize the processing potential of this machinery,
which can contribute to higher costs when considering the full life-cycle costs of the compost
operation. Therefore, Lock Haven should look to increase the quantity of leaves accepted and
processed. Within a certain operational cost balance, the more quality compost that can be
produced and sold, the better Lock Haven will be able to offset the operational costs. At the
same time, Lock Haven will increase operational costs as the number of times windrows are
turned increases. Typically, turning leaf and yard waste windows twice in the first couple weeks
of arrival is recommended. Additional turnings once-per-month for 6-8 months until the material
is ready for curing is a commonly used schedule. It is noted that some compost facilities
increase turning frequency to as often as weekly or multiple times per week to reduce the time
the material is in the active windrow compost phase. This is usually done to expedite the
production and sale of finished compost material, which in turn creates space at the compost site.

Increased turning increases operational costs; therefore, this activity should be managed carefully
to determine the economic cost benefit. When not in use by Lock Haven, the turner could be
rented to other municipalities to optimize equipment use and to help Lock Haven offset compost
site costs.

CASE WHEEL LOADER EVALUATION
GF has observed Case wheel loaders at the majority of compost sites operated in Pennsylvania.
Operators have been satisfied with Case loaders, and their operation costs and maintenance have
been routine, not problematic. Compost site operators report routine maintenance cost for Case
loaders being $1,000 - $2,000 per year. Because Case is a reliable wheel loader, available from
local dealers (such as Groff Tractor), and is suited to pull the Wildcat TS 514, GF evaluated the
proposed Case 621D loader for its suitability and compared it to the Case 621E and 721E. GF
has assumed that the wheel loader will be used regularly on an open-space compost site and that
the City of Lock Haven will continue to expand its compost operation.

8.1
Case Wheel Loader Comparison Summary
GF believes the Case 721E loader is a sound choice for Lock Haven’s compost operation and it
fits well into the plan for a growing regionalized compost facility. The additional vehicle weight
and horsepower is more suited for pulling the straddle turner and for continuous material
handling. The E-series of Case loaders, including Case 721E, has improved operator
access/viewing of daily service checkpoints that facilitates vehicle monitoring (i.e. preventative
maintenance) and overall maintenance ease. For managing yard waste and compost, the
3.5 bucket capacity on the Case 721E is operationally efficient compared to smaller volume
buckets; moving more material each scoop.
The 721E is a safer vehicle than the proposed Case 621D because the modifications to the cab
increase visibility for the operator. Compost sites can be high-traffic areas and operator view is a
critical feature. The additional visibility of the bucket is particularly beneficial for composting
operations because the operator can more easily identify unwanted debris before it is loaded,
potentially causing costly damage to processing equipment like a grinder or screener. The
additional bucket lift height of the Case 721E ensures the ability to load larger trucks with
compost. Case touts the E-series for the operator comfort and ergonomics that can improve
operator productivity. Similar to the windrow turner, optimizing the usage of the wheel loader
will require the facility to increase its incoming leaf and yard waste volumes.
State College Borough successfully used the Case 621 for years at their compost facility, but
recently moved to the Case 721E to improve operation efficiency, to reduce overall wear and tear
on the wheel loader, and to load tri-axle trucks with compost.
8.2
Other Considerations for Wheel Loaders
If Lock Haven has dedicated equipment operators, they should be included in the decision
making process for the wheel loaders. Equipment operators may have experience with, and be
comfortable on certain types of equipment - this should be factored into the final equipment
choice. For example, the Lehigh County Compost Facility uses Case loaders for some things but
uses John Deere loaders primarily for compost site operations because their operators felt
John Deere loaders were more stable on the uneven terrain on Lehigh’s compost site.
The Case 621D, 621E and 721E are all suitable equipment for working on a compost site. The
E-series of Case loaders is an improvement over the D-series that improves the long-term
operational efficiency, safety and maintenance compared to the Lock Haven -proposed
Case D-series. As a dedicated loader for a compost facility, expected to be worked frequently as
Lock Haven’s program expands, the Case 721E has advantages and efficiencies over the 621D
and 621E.

CONCLUSIONS AND RECOMMENDATIONS
9.1
Conclusions
At the current time, Lock Haven delivers leaves to a 2-3 acre Permit-By-Rule compost facility
located at the Waste Water Treatment facility and brush is taken to the Clinton County Solid
Waste Authority. With recent additions of yard waste collections and improvements to the leaf
waste collection program, the City of Lock Haven has taken steps to ensure its program complies
with Act 101 and applicable PADEP guidelines. With additional collections and increased
program awareness, the volume of leaves and other yard wastes generated by Lock Haven will
increase, and will require processing, usually into compost or mulch. In this evaluation, GF
provided technical guidance to Lock Haven in the selection of suitable leaf windrow turning
equipment to support a sustainable compost operation. Lock Haven proposes a Wildcat TS-514
windrow turner and a Case 621D wheel loader, as submitted in their approved Section 902
Recycling Grant.
Lock Haven proposes to identify and operate a larger compost site in the future that may
supplement the leaf and/or leaf processing needs of several local municipalities. This regional
approach to composting can be more sustainable than managing only Lock Haven generated yard
waste because finished compost can be sold for revenues, tip fees may be assessed for dropping
off materials for processing, and cost sharing arrangements for processing equipment can all be
used to help offset operational costs.
9.2
Recommendations
Based on our evaluation of equipment, and with the understanding that Lock Haven plans to
expand the compost operation in the future, GF recommends Lock Haven procure the following:
Wildcat TS 514 – Windrow Turner - $92,900 (as quoted to Lock Haven)
Case 721E – Wheel Loader/quick coupler/3.5 cubic yard bucket - $135,000 (estimated)
NOTE: The recommendation for the 721E including a 3.5 cubic yard bucket, which is a larger
loader than originally proposed by Lock Haven, assumes that the loader will be dedicated for
use at the compost site and not used in confined areas and/or for handling of other non-leaf
and/or yard waste materials. For example, a smaller loader operates better when space is
limited and a smaller bucket size (e.g. 2.75 cubic yards) or possibly a multi-functional bucket
would be recommended for a loader used to handle fine aggregates, perform grading, etc.
Although GF did not complete a leaf waste collection program analysis or a compost site
evaluation during this study, we obtained background information on these programs from Lock
Haven. Based on our experience with compost operations, and based on information reviewed
during this evaluation, GF recommends Lock Haven:
Prohibit the use and delivery of plastic bags to Lock Haven’s leaf waste collection program.
Paper bags and/or hard containers can be used as leaf and yard waste collection containers.
Plastic bags are not part of a sustainable compost operation because they increase handling/labor

costs, can damage or slow compost equipment, require disposal, and reduce the value of finished
compost.
Use the calculations provided in this Report to more accurately estimate leaf quantities and to
help estimate the windrows’ size and land area requirements. Prior data based on 5.5 cubic
yard leaf boxes incorrectly underestimated total annual quantities.
Dump loads of leaves in rows/windrows on site as they are delivered, not in piles to be
reconfigured later. Turn leaf windrows with the TS-514 approximately once per week in the
first month after delivery and then 1-2 times per month for the following 5-7 months. Cure
leaf compost 2 months before distribution. It is noted that the compost turning will
accelerate the compost process to a point, but a balance must be struck between the compost
process, particle size reduction from turning, and increased operating costs. Excess turning
of leaves will restrict air flow within the windrows and slow down composting unless a
bulking agent like woodchips is introduced.
GF recommends one or more Lock Haven staff that will work on the compost site is certified
in composting through the Professional Recyclers of PA (PROP) compost courses or takes
some other composting course to understand the compost process.
Since the current compost site is not paved, and rutting from equipment can lead to water
ponding, reduced operational efficiency, and can cause additional wear on equipment, it is
recommended Lock Haven conduct routine site maintenance/repair around the windows. If
Lock Haven relocates and expands its compost operation, it is recommended Lock Haven
pave the area used for active windrow composting.
Identify one or more suitable regional compost sites within 12 months that has up to five
(5) acres for active composting and 2-5 additional acres for curing, traffic ingress/egress,
equipment storage, finished material loading, and future expansion. The existing WWTP
composting operation will benefit by moving to another site that will have capacity to accept
more material, eliminate operating restrictions that may be associated with the WWTP
location, and to further maximize the opportunity of the site as an economically sustainable
site with benefit to several local communities.
Continue a positive ongoing relationship with the Clinton County Solid Waste Authority to
serve as a processor for yard waste and to use as a resource for equipment (i.e. grinder and
trommel screen). It is recommended Lock Haven rent both pieces of equipment from the
Authority as needed and use the trommel screen to increase the quality and value of compost
sold by Lock Haven. Equipment and labor sharing should be incorporated into the compost
operation. Provided there is sufficient area at Lock Haven’s compost facility, it is suggested
Lock Haven accumulate brush on site, and periodically rent the grinder from the Clinton
County Solid Waste Authority for processing to allow Lock Haven to use and/or sell mulch.
In the future, Lock Haven should sell finished compost and mulch and also charge tip fees
for incoming loads if commercial vendors deliver to the site.
When Lock Haven has a comfortable handle on operating the compost facility, it could
identify vendors (e.g. landscapers) that can deliver truckloads of grass on a
scheduled/managed basis. Adding nitrogen in the form of grass to leaf composting will

accelerate compost and improve the quality of the compost when grass is spread atop
windrows and turned into windrows within 24 hours. Landscapers, or perhaps Lock Haven
municipal crews/projects, could be a source for grass clippings.
Submit for reimbursement through the Act 101, Section 902 Recycling Grant for any
additional eligible recycling program and compost costs, including the outstanding cost
balance for the recommended Case 721E, which is roughly $40,000 more than the proposed
Case 621D.
