Re: A-1 Organics / Salazar Family Farm Composting
Dear Greg,
The purpose of this letter is to supply the Application
requirements as outlined in the Use by Special Review Procedural
Guide and Application with regard to the A-1 Organics Composting
site located on property owned by John, Jacob, Esteban, and Pete
Jr. Salazar as referenced in your notice of violation number VI -
1970 _
We have met with all parties who have expressed an interest in this
operation, and have attempted to address any areas of concern that
they may have concerning it.
The following information corresponds to the numerical Application
requirements in the Procedural Guide.
1. A COMPLETED APPLICATION FORM IS ATTACHED.
2. A DETAILED DESCRIPTION OF THE PROPOSED OPERATION AND USE SHALL
BE SUPPLIED. DETAILS FOR THE FOLLOWING ITEMS, WHEN
APPLICABLE, ARE REQUIRED.
2.1 EXPLAIN PROPOSED USE.
The site is to be used to stabilize and process (compost)
dairy manure, feedlot manure, and other non hazardous
organic matter including municipal yard waste and or
sludge, into weed free, odor free, and vermin free
compost/soil amendment. All organic materials will be
non-toxic or non -hazardous in nature as defined by the
Weld County Health Department. All material will be
processed in a manner that will control nuisance
conditions.
The site is not a disposal site. No wastes will be
permanently disposed of at this site.

2.2 EXPLAIN NEED FOR USE.
Aurora Dairy Farms operates a permitted dairy facility
approximately 1/2 mile south of the compost site. The
dairy milks an estimated 4,000 dairy cows. Annual
manure/bedding production is approximately 100,000 to
125,000 cubic yards. These raw dairy and other feedlot
wastes produced in the area are generally stockpiled in
large quantities until such time as local agricultural
field application can be accomplished.
Stockpiles can reach rather large volumes if application
windows are restricted. Weather, as an example, may
cause larger amounts of manure to accumulate as a result
of increased bedding practices and lack of fields that
can receive raw products. Costs to the Dairy for
transportation of the manure can also be excessive.
Composting of this primary source of organic waste will
convert it into a stabilized soil amendment product.
Raw feedlot manure and other organic wastes often contain
weed seeds which when applied to farm fields result in
increased field weed population and related costs of
eradication. Weed control often requires chemical
applications. Composting of the manure will eradicate
weed seed and increase the waste products agronomic, and
economic value.
Composting accelerates the decomposition of the wastes.
When completed, nutrients contained in the compost are
immediately available to the plant. Those not required
remain stable and are used by the plant at a later date
as opposed to being lost.
Composting of organic wastes greatly reduces in the
beginning, and at process completion eliminates
unpleasant odor's associated with these types of organic
wastes. Composted wastes pose very limited risk to
ground and or subsurface water sources.
Composting expands the market opportunities beyond
limited agricultural outlets to include commercial,
consumer, and even manufacturer markets. This expansion
results in year round distribution opportunities which in
turn reduces the risk of excessive stock piling of raw
products.
HWY 66 Composting Site 2
952087
Weld County Planning Services
March 25, 1994
If stockpiling of completed compost is required, the
product is odor free, weed free, and stabilized, and can
remain in storage for an indefinite period of time
without negative environmental impact.
The composting process begins very soon after receipt of
the raw products. This procedure results in more rapid
and efficient control of potential nuisance conditions
that could be experienced with raw products.
Composting also reduces the amount of truck traffic
associated with the handling of the feedlot, dairy, and
other organic wastes that may be blended and composted.
The amount of raw material received from the dairy and
feedlots being transported to the site will remain the
same as if the site were not in existence. However, the
composting operation results in up to a 40% reduction of
volume via normal decomposition, which results in less
product that needs to be transported from the site to end
users.
Composting of these wastes also lessens field compaction
when used as an agriculture soil amendment. Normally, 25
to 30 tons per acre of raw manure is spread to meet crop
requirements. With compost, 3 to 6 tons per acre are
normally applied, resulting in fewer trips across fields.
Flotation type application equipment is used, which
results in less field compaction.
Compost is also very high in organic matter. Organic
matter is valuable and needed in local soils to assist in
controlling erosion, and to increase water holding
capacity.
Municipal yard waste, wood wastes, and sludge are
currently disposed of in landfill's. Raw sludge is often
applied directly to farm fields. New EPA 503 regulations
have classified composting as an approved method of
producing a class "A" soil amendment product from
municipal sludge.
Class "A" sludge can basically be managed as a non-
restricted soil amendment. Manure has been and continues
to be used as a bulking agent for composting of municipal
sludge.
HWY 66 Composting Site 3
952087
Weld County Planning Services
March 25, 1994
Any sludge blended and used in the composting process
will meet all EPA, County, and State Health Department
requirements for processing in this manner. Composting
will lessen pressure on existing landfill's, and will
complete the recycling circle to return valuable organic
matter back to nature as opposed to disposing of it. It
will also stabilize sludge prior to application to
agricultural land or use as a consumer market soil
amendment.
2.3 EXPLAIN THE TYPES OF EXISTING USES ON SURROUNDING
PROPERTIES.
The surrounding uses are agricultural and compatible with
Applicant's facility. Neighboring properties consist of
farms, and livestock feeding operations.
2.4 THE DISTANCE OF THE PROPOSED USE TO RESIDENTIAL
STRUCTURES IN EACH DIRECTION.
South - Salazar family residences are located
approximately 3,000 feet south of the southern boarder of
the site.
North - Approximately 2,200 feet on direct line to the
Northwest from the northwest corner of the site.
West - Approximately 3,000 feet on direct line from the
western boundary of the site.
East - No residences within approximately 2 miles from
the eastern boundary of the site.
(See vicinity map for additional residences.)
2.5 THE MAXIMUM NUMBER OF USERS, PATRONS, MEMBERS, AND
BUYERS.
The site is not open to general public use.
The main supplier of organic waste will be Aurora Dairy.
It is anticipated that additional suppliers will be added
within site limitations and restrictions. The number of
suppliers being served will correlate directly to the
sites ability to properly handle the material received
without creating nuisance conditions. Should the amount
HWY 66 Composting Site 4
952087
Weld County Planning Services
March 25, 1994
of manure received exceed the ability of the site to
properly windrow it, the excess amount will be provided
to local farmers for field application. Should receipt
of other suppliers materials exceed the sites capacity to
properly handle them, then receipt of material will cease
until such time as proper handling capabilities are
restored.
Shipments of product are done in bulk, to a number of
customers. Trucking is coordinated through A-1 Organics.
2.6 THE NUMBER OF EMPLOYEES, NUMBER OF SHIFTS, AND HOURS OF
OPERATION.
The number of employees operating on the site will range
between 1 to 5. Hours of operation will normally be
between 6:00 AM and 5:00 PM, Monday through Saturday.
Evening or night time operations will occasionally be
required due to extreme weather conditions, special
shipment requirements, or emergency situations.
2.7 THE TYPE OF WATER SOURCE FOR THE PROPOSED USE.
No potable water source is generally required for normal
operations. When additional water for composting
operations is required it will be accessed from surface
water retention pond, existing irrigation water sources,
or hauled in via tank trailer. Drinking water will be
provided via portable dispenser or other approved
source.
2.8 EXPLAIN THE ACCESS ROUTE(S) TO BE UTILIZED FOR THE
PROPOSED USE.
Access routes will be off of HWY 66, via existing
driveway.
(See vicinity map)
2.9 EXPLAIN TYPE, SIZE WEIGHT AND FREQUENCY OF VEHICULAR
TRAFFIC ASSOCIATED WITH THE PROPOSED USE.
An average of between 4 semi -truck rigs with end dump
trailers access the site each day to remove finished
product. Occasionally product shipments may require up
HWY 66 Composting Site 5
952087
Weld County Planning Services
March 25, 1994
to 20 truck loads per day. These trucks when loaded will
have a gross weight of approximately 80,000 lbs.
The dairy cleans its pens on an on going basis. A tandem
dump truck (gross loaded weight not to exceed 54,000 lbs)
travels to the site 4 to 10 times per day hauling manure.
Additionally, the dairy often does a large cleaning once
every three months. For this cleaning they use end dump
semi -truck rigs as described above, as well as tandem
dump trucks. This process normally takes 3 to 5 days
during which up to 80 trucks per day will access the site
or farm field locations.
Passenger car and or pickup traffic will account for an
average of 3 to 4 trips per day. These vehicles weigh
between 2,000 to 4,000 #'s GVW.
2.10 THE TYPE OF SEWAGE FACILITIES FOR THE PROPOSED USE.
Sewage facilities will meet Weld County Health Department
requirements. Employees have access to existing rest
room facilities located at the dairy. The facility is
not open to the public. If required, a vault containment
facility will be installed and pumped per Health
Department requirements.
2.11 A DESCRIPTION OF THE PROPOSED FIRE PROTECTION MEASURES
ASSOCIATED WITH THE PROPOSED USE.
The compost is "wet" (40% to 60% moisture) in nature and
is non-flammable. Trucks entering the site will meet DOT
requirements regarding fire extinguisher's. No permanent
buildings will be constructed on the site.
2.12 THE TYPES AND MAXIMUM NUMBER OF ANIMALS TO BE
CONCENTRATED ON THE USE BY SPECIAL REVIEW AREA AT ANY ONE
TIME.
No animals will be confined on the site.
2.13 THE TYPE AND SIZE OF ANY WASTE, STOCKPILE OR STORAGE
AREAS ASSOCIATED WITH THE PROPOSED USE.
Potential organic materials to be composted include dairy
manure, wood products and bi-products, food process
waste, municipal sludge, and yard waste. All materials
HWY 66 Composting Site 6
952087
Weld County Planning Services
March 25, 1994
received at the site will be incorporated into windrows
as soon as possible, or processed and shipped to other
locations.
Some storage of liquids or solid organic wastes will be
required. In most cases, any liquid received will be
applied directly to windrows. If liquid storage is
needed, it will be facilitated in portable above ground
storage tanks, no larger than 21,000 gallons in capacity.
Wood and other solid materials will be stored in
stockpiles no larger than 12 feet in height. Storage
piles of raw and finished materials will be located at
various locations around the site as required by
operations. Total storage of raw materials (not in
process) will not exceed 150,000 cubic yards at any one
time.
All wastes will be handled in a manner that will control
nuisance conditions. Stockpiles of finished compost will
not exceed twelve feet in height.
Efforts to avoid stockpiling of raw material will be
made. Excess manure will be provided to area farmers.
If other wastes being received exceed the sites capacity
to properly handle them, receipts will be stopped until
such time as they can be properly received and handled.
2.14 THE TYPE OF STORM WATER RETENTION FACILITIES ASSOCIATED
WITH THE PROPOSED USE.
Storm water which falls on the site will be directed to
specific retention areas. Water that accumulates in
these areas will be removed and applied to windrow
material or allowed to evaporate if small quantities are
present. No surface water will be allowed to leave the
site perimeter. The materials being processed are highly
absorbent in nature and will absorb a great deal of storm
water which may fall on the site.
2.15 THE TIME SCHEDULE AND METHOD OF REMOVAL AND DISPOSAL OF
DEBRIS, JUNK AND OTHER WASTES ASSOCIATED WITH THE
PROPOSED USE.
Wastes generated that cannot be composted will consist of
rocks, some plastic, twine, and other screening's and
debris contained in the raw products. Wastes or debris
HWY 66 Composting Site 7
952087
Weld County Planning Services
March 25, 1994
that cannot be composted will be properly contained and
disposed of at an approved disposal site such as a
certified land fill. A containment pit will be used to
inventory the non-compostable wastes until they are
disposed of.
Waste disposal will be done every quarter or when amounts
accumulated warrant it. Estimated quantities will
generally run less than 20 cubic yards per month.
Wastes or debris that cannot be composted will be
disposed of on a quarterly basis via truck to approved
disposal sites.
2.16 EXPLAIN PROPOSED LANDSCAPING PLANS AND EROSION CONTROL
MEASURES ASSOCIATED WITH THE PROPOSED USE.
A berm will encompass the site, with shrubs or trees on
the west and north west side of the site to provide a
windbreak and also improve visual esthetics as viewed by
neighbors to the west and northwest.
The site was previously used for dry land farming. The
composting operation increases the organic matter content
of the soil, thus reducing wind erosion potential. The
nature of the operation require windrows of product
continually in process, which also reduce erosion
potential.
The site will be bermed where necessary to contain
surface water. It is located on top of a hill with
drainage sloping away from the center of the site. The
area around the site is farm land.
The surface soil has low permeability as stated in soil
survey information.
2 17 RECLAMATION PROCEDURES TO BE EMPLOYED UPON CESSATION OF
THE USE BY SPECIAL REVIEW ACTIVITY.
All raw materials will be finished to soil amendment
grade, then marketed or marketed to existing landscape or
agricultural needs. Berm's will be leveled and site
returned to its original condition and use.

952087
Weld County Planning Services
March 25, 1994
2.18 A TIME TABLE SHOWING THE PERIODS OF TIME REQUIRED FOR
CONSTRUCTION AND START-UP OF THE PROPOSED USE.
No building construction is projected at present. Site
preparation will be limited to construction of
containment berm, surface water retention area, and
minimal landscaping. These items should take less than
45 days to complete.
3. THE FOLLOWING WRITTEN MATERIALS AND SUPPORTING DOCUMENTS SHALL
BE SUBMITTED AS A PART OF THE APPLICATION:
3.1 A STATEMENT EXPLAINING HOW THE PROPOSAL IS CONSISTENT
WITH THE WELD COUNTY COMPREHENSIVE PLAN.
The application is consistent with the Weld County
Comprehensive Plan (WCCP) for several reasons.
1). The WCCP states that the way that land is presently
used is one of the most important considerations in land -
use planning. The land on which the compost site is to
be located has been primarily used for manure storage in
the past. It was covered with weeds, and some wheat as
erosion control. The land is considered non-productive
agricultural farm land in that what has not been used for
raw manure storage was in cover crop only. Composting
will improve the quality of the "manure". Storage of
finished compost will pose no threat to the environment.
2). The WCCP indicates an intent to encourage
agricultural and farm use, along with those activities
that promote products and services associated with,
supplemental to, and dependent upon agriculture. The
compost site utilizes waste generated by agriculture,
processes it into a more beneficial soil amendment, and
either returns it to agricultural or markets it as a
commodity. It provides a cost savings both from a
disposal, and an application perspective to agriculture,
thus providing economic benefit. It is derived from, and
is directly related to agriculture.
3). The process also is consistent with the county's
goal of promoting positive, environmentally responsible
alternatives for recycling waste as opposed to disposing
of it.
HWY 66 Composting Site 9
952087
Weld County Planning Services
March 25, 1994
4). The WCCP states that Weld County is a "complete farm
and food system". The composting operation is a
instrumental part of the complete system by producing a
product ready for purchase by consumers and agriculture
after it has been processed. Compost becomes a commodity
much like corn. The site will create new markets for
agricultural related products.
5). The WCCP promotes industries that purchase products
grown or produced by agriculture. The composting process
reduces costs, and in effect purchases products (waste)
from agriculture.
6). The process can be categorized as a new and
innovative method for using and promoting agricultural in
Weld County. It adds to the chain of purchases related
to agricultural production.
7). The composting operation is an exporter of goods and
importer of income to Weld County. Local trucking and
labor is used in the processing.
8). The compost operation will capitalize on the quality
of a natural resource...organic waste.
9). A-1 Organics is a rural based organization. A-1 has
operated composting operations in a responsible manner
for nearly 18 years. Included in their experience is
composting operations involving all of the potential
products to be composted at this site. The site promotes
the "necessary interdependent relationship between urban
and rural areas", as put forth in the WCCP.
10). The site will reduce costs of agricultural
production which is a principal concern of the WCCP.
11). "Weld County Agricultural Goals and Policies have
been developed to support and preserve the agricultural
industry and farming as a way of life." The composting
site is consistent with this statement from the WCCP.
12). The operation will encourage the preservation of
the agricultural uses in Weld County. It will promote
the agricultural use of prime agricultural land by
providing low cost soil amendments that will improve the
quality of farm land. It is directly dependent upon the
agricultural industry.
HWY 66 Composting Site 10
952087
Weld County Planning Services
March 25, 1994
13). It uses an appropriate location for a commercial or
industrial use of agricultural land that at the same time
benefits agricultural. It is consistent with the WCCP's
goal of promoting the conversion of geologically suitable
non -prime agricultural land to solid, liquid, and waste
water disposal (processing) sites.
14). The site is consistent with the WCCP Environmental
Quality and Natural Resources guidelines. It does not
promote erosion, reduced water quality, loss of
productive farmland, and reduced fish and wildlife
habitats. It assists in taking an active part in
conserving and preserving he environment by providing a
responsible proven process for responsibly converting
waste products into usable soil amendments.
15). The composting operation does not exceed the
physical capacity of the land and water needed to
accommodate the operation, nor does it have an adverse
effect on water quality and quantity.
3.2 A STATEMENT EXPLAINING HOW THE PROPOSAL IS CONSISTENT
WITH THE INTENT OF THE DISTRICT IN WHICH THE USE IS
LOCATED.
The Applicants uses are agriculturally based in nature
and therefore very compatible with surrounding community.
3.3 IF APPLICABLE, A STATEMENT EXPLAINING WHAT EFFORTS HAVE
BEEN MADE, IN THE LOCATION DECISION FOR THE PROPOSED USE,
TO CONSERVE PRODUCTIVE AGRICULTURAL LAND IN THE
AGRICULTURAL ZONE DISTRICT.
Applicant's site is located in the A district
(agricultural) due to its close ties to agriculture and
dependency on it. The site was chosen because of its
proximity to a large feedlot and dairy operations, access
to highway and interstate highway's, and its previous
use. A large part of this land was used to stockpile
large quantities of raw manure for several years. The
majority of the land which had not been used for
stockpile use was considered poor farm ground and was
non-productive.
The site is located on a dry land hill top. It's soil
types have low permeability (see soil map) which will
assist in sealing the working area. The site has
HWY 66 Composting Site 11
952087
Weld County Planning Services
March 25, 1994
natural drainage from the center to the perimeters, and
then to the eastern holding pond.
3.4 A STATEMENT EXPLAINING THERE IS ADEQUATE PROVISION FOR
THE PROTECTION OF THE HEALTH, SAFETY AND WELFARE OF THE
INHABITANTS OF THE NEIGHBORHOOD AND THE COUNTY.
The applicant has the reputation of being one of the
premier composting operations in the Rocky Mountain
Region. The applicant has been in the composting
business for nearly 18 years and enjoys a responsible and
responsive reputation with its neighbors.
The operational plan will include precautions to protect
the health, safety and welfare of the inhabitants of the
neighborhood and county. (See operational plan) The
applicant will remain responsive to any concerns raised
by the general public.
3.5 A STATEMENT EXPLAINING THE USES PERMITTED WILL BE
COMPATIBLE WITH THE EXISTING SURROUNDING LAND USES
(INCLUDE A DESCRIPTION OF EXISTING LAND USES OF ALL
PROPERTIES ADJACENT TO THE PROPERTY).
Uses of the site will remain compatible with the
surrounding agricultural land uses as described earlier.
All adjacent property is used for crop land, animal
feeding, and or dairy operations.
3.6 A STATEMENT EXPLAINING THE PROPOSED USE WILL BE
COMPATIBLE WITH THE FUTURE DEVELOPMENT OF THE SURROUNDING
AREA AS PERMITTED BY THE EXISTING ZONE AND WITH FUTURE
DEVELOPMENT AS PROJECTED BY THE COMPREHENSIVE PLAN OF THE
COUNTY OR THE ADOPTED MASTER PLANS OF AFFECTED
MUNICIPALITIES.
The WCCP states that agricultural activities and
operations are to be promoted and protected in this area.
This operation is consistent with that goal, and current
zoning.
The closest municipality to the Applicant's property is
Platteville. Platteville is a community largely
associated with farming and its Comprehensive Plan
fosters the further development of agriculture much the
same as the overall WCCP. Therefore, the Applicant is
HWY 66 Composting Site 12
952987
Weld County Planning Services
March 25, 1994
compatible and consistent with the Comprehensive Plans of
both Platteville and Weld County. Since no problems have
arisen between Applicant and the Town of Platteville to -
date, further development of the composting operation
does not seem likely to create any future problems.
Platteville can expect to enjoy increasing benefits from
the Applicant.
The town of Mead has annexed a parcel of land located
approximately 1/2 of a mile to the west of the
Applicant's facility. This island annexation is being
developed as a small subdivision.
3.7 A STATEMENT EXPLAINING THE USE BY SPECIAL REVIEW AREA IS
NOT LOCATED IN A FLOOD PLAIN, GEOLOGIC HAZARD AND WELD
COUNTY AIRPORT OVERLAY DISTRICT AREA; OR THAT THE
APPLICATION COMPLIES WITH SECTION FIFTY (50), OVERLAY
DISTRICT REGULATIONS AS OUTLINED IN THE WELD COUNTY
ZONING ORDINANCE.
The facility is not located within a flood plain,
geologic hazard, or Weld County Airport Overlay District
area.
3.8 PROOF THAT A WATER SUPPLY WILL BE AVAILABLE
WHICH IS ADEQUATE IN TERMS OF QUANTITY,
QUALITY, AND DEPENDABILITY (E.G. A WELL PERMIT
OR LETTER FROM A WATER DISTRICT).
Drinking water will be provided for employees via
portable unit dispensers. The operation requires little
production water, which will be accessed from local
irrigation sources.
3.9 A COPY OF THE DEED OR LEGAL INSTRUMENT IDENTIFYING THE
APPLICANT(S) INTEREST IN THE PROPERTY UNDER
CONSIDERATION. IF AN AUTHORIZED AGENT SIGNS THE
APPLICATION FOR THE FEE OWNER(S), A LETTER GRANTING POWER
OF ATTORNEY TO THE AGENT FROM THE PROPERTY OWNER(s) SHALL

5. GENERAL COMMENTS.
A-1 Organics has made substantial effort to address the
potential concerns of neighbors of the site. We have had
several meetings with the land owner directly to the west and
north who has expressed the greatest concern over the site.
The subdivision mentioned in section 3.7 is named Grand View
Estates. It is a new subdivision that was not in place when
the dairy manure was being stored and subsequently composted
on the Salazar site. However, A-1 Organics' desire is to
recognize the concerns of its neighbors, and address
reasonable concerns in a prompt and responsible manner.
Input from these neighbors was considered in development of
this application and operational plan. We have committed to
them that as additional types and or sources of materials are
considered for composting, they will be informed and educated
in the details of the products being composted and the
operational procedures used to compost them. This is a good
faith effort intended to mitigate and avoid potential conflict
before it occurs.
Responsible composting operations are not the problem, but
rather are a valuable solution to waste management problems
facing Weld County today. Facilities such as those employed
by A-1 Organics are needed not only to turn waste disposal
problems into environmentally positive solutions, but also to
provide a valuable environment for development of new methods
and techniques for dealing -with what was once seen as a
societal problem.
It is facilities such as this that will add to the quality of
life enjoyed by the citizens of Weld County by safely and
effectively processing the waste generated by our society.
The Wilson family, who own and operate A-1 Organics have been a
part of Weld County since 1887. Duane Wilson, the president of A-i
Organics has lived his entire life, except for military service, in
Weld County, as have his son's Tom, Chuck and their families.
Lambland Inc., DBA A-1 Organics was formed in 1975 to
HWY 66 Composting Site 15
952087
Weld County Planning Services
March 25, 1994
compost the sheep manure produced by their lamb feeding operation.
They have been, and will continue to be, responsible and
conscientious citizens of Weld County. The manner in which this
facility will be operated is consistent with the work ethics,
dedication and commitment that the Wilson family has exhibited in
Weld County for over 100 years.

COMPOST SITE OPERATIONAL PLAN
Composting operational procedures will vary somewhat according to
the organic waste being composted. All operational procedures will
be done in such a manner as to adequately control the potential for
nuisance conditions to occur.
1. Management and Operation:
The site will managed by a full time site manager employed by A-1
Organics. He will be on site to monitor activities and conditions
and manage accordingly.
A-1 Organics is a Colorado Company involved with commercial
composting of all types of organic materials. A -1's corporate
office is located in Eaton Colorado. The company has been involved
with full scale operational composting activities since 1975. The
company has a broad base of experience in compost production and
marketing of numerous types of organic bi-products including most
types of animal manures, yard waste, oil wastes of various types,
biological pharmaceutical bi-products, waste water treatment plant
bio-solids, food process bi-products, various waste woods, and
paper bi-products to name a few.
A-1 currently processes over 150,000 cubic yards of raw materials
and markets in excess of 100,000 cubic yards of finished product
per year through both bulk and bag markets. Products produced and
sold include several types of compost, planting soils, top soils,
nursery mix's, peat moss substitute, landscape mulches, and
agricultural soil amendments. The facility in Eaton includes a
bagging facility that is capable of producing 1,000,000 bags per
year in its current configuration. A-1 also markets through over
20 bulk distributors, several garden centers, nurseries, hardware
stores, and other retail outlets. A-1 Organics not only produces
a quality product, but capably closes the loop by marketing the
product it produces.
2. Materials and Estimated Volumes:
It is projected that up to 150,000 tons of waste per year can be
composted on the site. Initial material to be composted will be
dairy manure. Additional future materials to be composted or
processed will include: Manure, Yard Waste (grass, leaves, twigs,
etc.), ground wood wastes such as pallets, food process wastes, and
municipal sewage sludge.

2.1 Addition of New Organic Bi-Products or Materials:
The Weld County Department of Health and Environment will be
advised in writing of any new materials proposed for
composting prior to initiation of site composting of such
product, and written approval to proceed with composting
obtained from the department prior to receipt of material.
Submittal information will include operational procedures.
All materials considered for composting will meet current and
future regulatory requirements for that specific material.
2.2 Receipt of unapproved wastes:
Materials received at the site will be visually inspected as
they are unloaded. If an unapproved waste is discovered, the
entire load will be rejected. A-1 Organics will exercise good
judgement in the selection of materials and clients allowed to
access the facility services. Either the receiving documents
or a file document will contain a statement from the
originator of the material that the shipment contains no
unapproved material, and that they are liable for its removal
and or disposal if it does. Any violation will immediately be
reported to the Weld County Department of Health and
Environment. Any unapproved waste will be disposed of at an
approved facility.
3. Procedure:
Composting of organic wastes has been a widely accepted practice
for centuries in communities throughout the world. In recent times
the process has become highly refined in specific applications for
animal manures, municipal wastes, various types of bio-solids, food
wastes, yard wastes, and other organic bi-products. Bio-solids
composting in the United States has been used for decades, and is
now designed and operated according to well-defined engineering
perimeters and procedures. Foremost among composting systems is
the aerated windrow composting method. The aerated windrow
technology has distinguished itself because of its reliability and
flexibility. This process can operate with varying bio-solids or
material characteristics and weather conditions. The process
produces a highly desirable end product, which is a stable, weed
free, and significantly pathogen -free soil amendment or
conditioner.

Weld County Planning Services

3.1 Composting Process Description
Composting is an aerobic process which allows microorganisms
indigenous to the material being composted to degrade a
portion of the organic material to carbon dioxide and water.
Successful composting occurs in the thermophilic temperature
range (130°F to 160°F). The elevated temperature is attained
by biochemical activity in the composting material, and no
input or heat energy is required. The process develops the
temperatures necessary to kill weed seeds and pathogens. If
bio-solids or other liquid materials containing organic matter
are composted, they are mixed with an amendment prior to
composting. The purpose of the amendment, typically wood or
bark chips, is to provide a carbon source, porosity for air
flow and oxygen transfer, structure and to absorb or balance
some of the moisture in the bio-solids.
The optimum moisture content for composting is about 50
percent (weight basis). Less moisture causes a retardation of
biochemical activity, and greater moisture may clog pore
spaces between particles, thus restricting oxygen transfer.
Such clogging would encourage anaerobic conditions in the
composting mass, with the resultant generation of unpleasant
odors. Anaerobic conditions and associated odor emissions are
effectively eliminated with proper facility design and
operation.
The final compost produced by the aerated windrow or static
pile method contains a high humus content similar to peat. It
is moist, dark in color, has no objectionable odor, and is
largely free of pathogenic organisms and weed seeds. Compost
increases the water holding capacity of sandy soils, improves
the structure of heavy clay soils, and increases the air
content of the soils, making it easier for plant roots to
penetrate. Compost typically contains relatively small
amounts of slow release nitrogen, phosphorus, and potash with
a typical fertilizer value of 1-2-0.2. The primary usefulness
of a compost product is as a soil amendment.
3.2 Basic Operational Procedure
Manure and other approved wastes will be transported to the
site via trucks and placed in windrows of approximately 12 -16
feet wide, and 6 feet tall. Windrows will be aerated
HWY 66 Composting Site 19
952087
Weld County Planning Services
March 25, 1994
with equipment designed for this task to provide composting
bacteria with oxygen.
The material will heat to temperature of between 125 to 140
degrees. Aeration procedures will continue intermittently for
approximately 6 weeks, or until such time as the material is
fully composted. When the composting process is completed,
the finished material will be screened, stockpiled, and
marketed.
Records indicating temperatures, aeration dates, and other
pertinent data will be maintained and made available to
appropriate regulatory agency's.
4. Site Preparation:
The site is nearly 1/2 mile north of State Highway 66, just west of
WCR 17. It is not accessible by the general public. The site is
crowned to direct surface run off to designated areas. The site
has been in operation for nearly 3 years, during which time, manure
has been mixed with existing soil and compacted to create a sealed
surface.
A perimeter berm will

be constructed with a surface water
inside of the berm. Shrubs and or trees

windbreak and esthetics enhancement. The
Surface water will be directed to a containment basins located
inside the berm area (see site map). The containment basins will
be lined with a manure/soil mixture and compacted to seal them.
5. Environmental Controls:
Surface Water:
The site is located at a higher elevation then the area
surrounding it. No water will breach the site from outside
the perimeter. Any excess surface water (run off) originating
or falling on the site will be directed to the control ditches
inside the berm, then to the retention areas. Water that
accumulates in the retention areas will be re -applied to the
windrows as needed to maintain proper moisture, used for dust
control on the site, or evaporated. No prolonged standing
water or puddling will be allowed.
HWY 66 Composting Site 20
952087
Weld County Planning Services
March 25, 1994
Ground Water:
All material is processed above ground. No prolonged ponding
or puddling of water of liquids will be allowed. The natural
soil located on the site has poor permeability
characteristics. Manure which has shown to be an effective
sealant for lagoons will be mixed with the existing soil. The
mixture will provide adequate sealing characteristics.
The site is nearly 100 feet above ground water elevations
indicated by the nearest well (within 3,000 feet of the site).
Airborne Materials:
The windrows will be kept moist and will crust over within a
short period after being turned. Fugitive dust will be
controlled via watering of traffic lanes if needed. Any
stockpiles of ground wood or material subject to movement by
wind will be watered or covered until such time as they can be
incorporated into windrows. APEN applications have been filed
with the Colorado Department of Health, Air Quality Control
Division.
Odor:
The composting process will mitigate odors. Any liquid
organic wastes used will be immediately incorporated into
windows. This procedure has proven to be very effective in
controlling odors. Wood and or finished compost will be used
to filter odors if required. Windrows will be maintained in
an aerobic condition. Finished compost has an odor much like
that of fresh turned earth. If necessary, non chemical
organic odor control agents that have proven effective on
other operations will be used.
Some odors are generated when the windrows are turned or
aerated. The wind sock will indicate direction to the site
manager. The site manager will refrain from aeration when
conditions indicate that excessive odors will be carried to
populated areas.

Vermin:
Frequent aeration of windrows will discourage nesting and
eradicate larvae. Heat and activity also discourages
burrowing vermin. Experience has shown that composting
actually eliminates fly's. Additionally, Colorado Dairy will
treat the compost site for fly's periodically when they are
spraying the dairy.
General:
All operations will be done in a manner to control nuisance
conditions. Periodic meetings with neighbors and adjacent
landowners will be held to maintain communication and address
any concerns they may have.

I. GENERAL LOCATION AND DESCRIPTION
The A-1 Composting Facility is located in approximately 4 miles East and 1.5 miles South of Mead,
Weld County, Colorado, also being located 3 miles East of I-25 and .5 miles North of CO 66. The
site is bordered on the North by a small concrete irrigation canal and the East, South, and West by
farmland. An irrigation lateral along the South of the site has been filled in apparently by farming
operations in this vicinity.
The site is irregular shaped and 29 acres in size, the majority of which is located within the northwest
Quarter of Section 20„ Township 3N, Range 67W, 6th P.M. The site contains compost windrows
consisting of dairy manure, feedlot manure and other non -hazardous organic matter including
municipal yard waste and/or sludge. The site also contains two oil tank batteries with accessory
structures and a portable storage area located in the vicinity of the high point of the site. Access is
available from CO 66 on a gravel road that runs North -South through the high point of the site.
Ground cover on the property consists of silt loam and silty clay loam with moderately slow
permeability. According to the SCS survey, this material extends to the depth of excavation for the
proposed ditches and ponds, therefore, clay or synthetic liners should not be necessary in the
proposed runoff storage areas. Also, the runoff that accumulates in these areas will be removed and
applied to the compost windrows. Based on these conditions, the proposed drainage improvements
should not alter the soils nor the basic ground cover type.
There are no major drainageways or irrigation facilities running through the site. The Weld County
Health Department is requiring on site drainage ditches and/ or berms along with retention ponds
to fully contain the 25 year 24 hour runoff event. According to the owner, the minimum area of the
site that is covered by compost is 25% which is expected to entirely absorb the design storm
precipitation. The remaining area of the site will generate runoff that will be fully contained for the
design event runoff in the proposed ditches and ponds as detailed further in this report.
II. DRAINAGE BASINS AND SUB -BASINS
The property lies at the top of an East-West ridge resulting in sheet flow runoff drainage patterns to
the North and South. A small area of farmland within the Westerly portion of the site currently
drains toward the composting area, however, the offsite drainage follows the same North and South
sheet flow drainage patterns and therefore does not appear to enter the site from any direction.
According to the FIRM Map for Weld County, the nearest floodplain is located approximately `/2
mile East of the site.
A rough topographic survey of the site was undertaken by Tuttle Applegate, Inc. to identify specific
drainage patterns on the site. Approximately 1/3 of the site is located East of the entry road which
drains to the East. Approximately 2/3 of the site is located West of the entry road where the drainage
is split to the Northeast and Southeast. The onsite drainage basins and patterns are shown on the
exhibits in this report.
952087
III. DRAINAGE DESIGN CRITERIA
Drainage improvements for the site have been designed in accordance with the City of Longmont
Storm Drainage Criteria Manual and the Urban Storm Drainage Criteria Manual. No known
drainage studies have been done for the site or for adjacent sites.
The design storm recurrence interval was obtained from the Weld County Health Department. The
25 year, 24 frequency event was used for the design of the berms, ditches, and retention ponds. The
Rational Method was used to calculate storm runoff. Minimum storage volumes for retention were
calculated using rainfall data from NOAA.
IV. DRAINAGE FACILITY DESIGN
The proposed drainage plan for the Composting Site utilizes the construction of a 1' high
berm/maintenance road along the entire perimeter which will act as freeboard for the design runoff
event and provide additional retention over the required volumes provided below. This road will also
prevent any possible farmland runoff from entering the composting area of the site. Drainage within
the site is proposed to be intercepted by three separate ditch and retention pond systems. The ditches
are proposed to function as combined conveyance and storage facilities and will be uniformly graded
from a depth of 0 feet to 3 feet. The ponds are proposed to be 3 feet deep. The owner will install
native seeding in these areas to control any possible erosion.

V. CONCLUSIONS
In summary, the proposed drainage improvements will not have an adverse impact on downstream
and upstream property owners. The drainage plan complies with all current applicable regulations,
requirements and criteria. Stormwater runoff for the 25 year, 24 hour event will be completely
retained on the site.

Manual. However, the channel design will also be analyzed with respect to initial storm
runoff and its effect made known. Whenever practical, the channel should have slow
flow characteristics, be wide and shallow, and be natural in its appearance and
functioning.
Channels will be designed in such a manner that critical depth and super -critical flows
are avoided. Channel capacities will be computed from Manning's Formula for uniform
flow.

DRAINAGE CRITERIA MANUAL MAJOR DRAINAGE
2.3.16 Design Depths. The maximum design depths of flow should also
recognize the scour potential of the soil -vegetative cover complex.
Scouring power of water increases in proportion to a third to fifth power
of depth and is also a function of the length of time flow is occurring.
As preliminary criteria, the design depth of flow for the major storm
runoff flow should not exceed 5.0 feet in areas of the channel
cross-section outside the low flow or trickle channel area.
2.3.1C Design Slopes. Grass lined channels, to function well, normally
have slopes ranging from 0.2 to 0.6 percent. Where the natural topography
is steeper than desirable, drop structures should be utilized.
2.3.1D Curvature. The more gentle the curves, the better the channel will
function. Centerline curves shall not have a radius that is no less than
two times the design flow top width when calculated using the depth under
2.3.16, but not less than 100 feet.
2.3.1E Design Discharge Freeboard. Bridge deck bottoms and sanitary
sewers often control the freeboard along the channel in urban areas. Where
such constraints do not control the freeboard, the allowance for freeboard
should be determined by the conditions adjacent to the channel. For
instance, localized overflow in certain areas may be acceptable and may
provide flow storage benefits. In general, a minimum freeboard of 1 to 2
feet should be allowed between the water surface and top of bank or the
elevation of the lowest floor of adjacent structures.
2.3.2. Grass. The grass species chosen must be sturdy, drought resistant, easy
to establish and able to spread and develop a strong turf layer after
establishment. A thick root structure is necessary to control weed growth and
erosion. In the Denver region a mixture of native and introduced grass species
has been used in establishing an erosion -resistant channel lining. The Soil
Conservation Service, Urban Drainage and Flood Control District and local
landscape architects can provide assistance in selecting grass mixtures which
have been successful and fit the site conditions found in the Denver area.

DRAINAGE CRITERIA MANUAL MAJOR DRAINAGE
Typical cross -sections suitable for grass lined channels are given in Figure
2-4.
2.3.4 Roughness Coefficients. The hydraulic roughness of man-made grass lined
channels depends on the length of cutting, if any, the type of grass, as well as
the depth of flow (11). Typical roughness coefficients are as follows:

*For straight channels without shrubbery or trees
The 0.7 to 1.5 foot depth in Table 2-4 is generally suitable for computing the
wetted channel portion for the initial storm runoff, while the greater than 3
foot depth is suitable for the major runoff computations. A depth of flow of
2.0 feet or more will begin to lay the grass down to form a smoother bottom
surface.

RE: Pertinent data required for the Site Specific Development Plan, A-1 Organics/Hwy 66
Compost Site.
Dear Bob:
At your request, Groundwater Specialists has complied and evaluated geologic, hydrogeologic, and
hydrologic data for the Site Specific Development Plan of A-1 Organics/Hwy 66 Compost Site.
The Compost Site is located on approximately 30 acres in the NW/4 of Sec. 20, T. 3 N., R. 67 W.,
in southern Weld County, Colorado. The Site is the highest point in section 20 and is on the top of
an elongated hill with an elevation generally greater that 4900 feet. This Site is approximately 120
vertical feet above the St. Vrain Creek floodplain.
GEOLOGY
The geology for this area has been mapped by Colton (1978) and Scott and Cobban (1965). The
geology shown on our attached Geologic Map is taken from Colton and the two measured geologic
dips are from Scott and Cobban.
The Site and the uplands of this area are underlain by what Colton maps as Eolium Deposits. These
deposits consist of windblown clay, silt (loess), sand, and granules. These deposits are generally less
than three feet thick and are light -brown to reddish -brown to olive -gray in color.
According to Colton's mapping, the Fox Hills Sandstone lies beneath the Eolium Deposits at the
Compost Site. Colton shows the Fox Hills cropping out along the west bank above the St. Vrain
valley and along the western tributary valleys (see attached Geologic Map). Colton describes the
952087
2
Fox Hills in this area as a brown, fine-grained silty sandstone interbedded with gray fissile shale,
with local thin coal beds.
Colton (1978) recognizes the Pierre Shale in the valleys to the west of the Site. He maps this as the
Upper Transition Member of the Pierre. This member consists of soft shaly sandstone with thin -
bedded sandy shale and large calcareous sandstone concretions.
The geologic strata in the bluffs to the west of St. Vrain Creek dip one degree to the southeast toward
the center of the Denver Basin.
The bedrock geology of this area is somewhat confusing because of the transition between the Pierre
and the Fox Hills. The assignment of the rocks to one or the other has always been controversial.
For purposes of allowing additional groundwater appropriation, the State Engineers Office considers
the Upper Transition Member sandstones as part of the Fox Hills. However, general geologic
consensus puts the base of the Fox Hills about 250 feet below the base of the Milliken Sandstone
Member of the Fox Hills.
Because of poor outcrops and the lack of a truly recognizable Milliken Sandstone Member, Scott and
Cobban (1965) mapped this area including the bluffs along St. Vrain Creek as the Upper Transition
Member of the Pierre Shale.
Robson (1983) reported the hydraulic conductivity of an undisturbed outcrop sample from the Fox
Hills Sandstone located in the SW NW of Sec. 20, T. 3 N., R. 67 W to be 0.7 feet per day.
Colton (1978) maps a narrow zone of Colluvium along parts of the western edge of the St. Vrain
flood plain. These Colluvial deposits are generally less than five feet thick, and consist of bouldery
to pebbly sandy silt and clay.
The extensive St. Vrain Creek valley and some narrow areas along major tributaries are mapped as
Alluvium. The thickness of these recent alluvial deposits is on the order of 35 feet. Older alluvial
gravels may be present beneath these younger alluvial deposits.
SOILS
Crabb (1980) recognized three soil types at the Compost Site. The Thedalund and Weld Loams and
the Wiley -Colby Complex. These soil types are 8 to 10 inches thick and formed as residuum from
shale or in eolian deposits. These uncompacted soils at the Site are characterized by slow water perk
rates and permeabilities ranging from 0.6 - 2.0 inches per hour to 0.06 - 0.2 inches per hour.
The soils at the Site are compacted and permeabilities probably approach 1 x 10' cm/sec (0.0001
inches per hour).
952087

PERMITTED WATER WELLS
Colorado State Engineers Office records show 12 permitted water well or monitoring wells within
a one mile radius of the Compost Site (Table 1). Of these 12 permitted wells, five are shallow holes
for monitoring purposes only, and the remaining seven wells are used for domestic or livestock
purposes. Five of the water wells are completed in the Alluvial deposits of St. Vrain Creek, and two
are completed in shallow older alluvium beneath the Eolium deposits (see the Geologic Map and
Table 2). The five monitoring wells are completed in the shallow older alluvium beneath the
Eolium.
There are no Fox Hills water wells in this area. Probably because there is no "true" Fox Hills
Sandstone, only the transition sandstones of the upper Pierre Shale. In addition there is not sufficient
saturated thickness of these transition sandstones.
Table 2 lists the important permitted well information. Permit No. 136175 at a total depth of 109
feet may be deep enough to encounter a bedrock sandstone, but the water production is primarily
from the alluvium.
SURFACE WATER FEATURES
Surface water features within a two mile radius of the Compost Siteare shown on the Surface Water
Feature Map (attached). The most significant feature is St. Vrain Creek. There are many irrigation
and drainage ditches and numerous small surface water impoundments. None of the surface water
features impact the Site. The topography of the Site is such that only direct on site precipitation
needs to be of a concern. On site precipitation can easily be contained by small collection ponds.
The Site is not a flood plain concern since it is more than 120 feet above the St. Vrain valley and
more than 50 feet above the small unnamed tributary to the north of the Site.

RE: Insitu permeability tests at the Hwy 66 Compost Site.
Dear Bob:
4730 Table Mesa Dr., Suite 1-34
Boulder, Colorado 80303
Phone & FAX (303) 494-8122
At your request, Groundwater Specialists have performed insitu permeability tests
for the three proposed retention pond sites at your A-1 Organics/Hwy 66 Compost
Site.
The testing was conducted June 26, 1995. The three proposed retention pond
sites are the North Pond. the East Pond, and the South Pond (see attached Site
sketch).
NORTH POND SITE - Percolation rate was 0.0227 inches per hour or approximately
1.6 x 10-3 centimeters per second.
EAST POND SITE - Percolation rate was 0.0642 inches per hour or approximately
4.5 x 10-3 centimeters per second.
SOUTH ?OND SITE - Percolation rate was 0.0812 inches per hour or approximately
1 x 10 centimeters per second.
These percolation rates are somewhat greater than we would have estimated,
however, the East and South Pond Sites (especially the South Pond Site) had
loose material which probably resulted in a faster rate. Additional compaction
with added moisture will lower the rate and we still believe the permeabilities will
approach 1 x 10-‘ centimeters per second.
If you have any questions or if additional tests are required, please call.
Very truly yours,

Dear Ms Jones,
In estimating truck ingress and egress events required for
normal land application of manure from the dairy in my
previous correspondence, I calculated access events
assuming that manure was taken directly from the dairy to
the field site. Using this assumption, we estimated that
access events necessary for manure to land application was
approximately 8,000 per year.
I felt it would be useful to point out that if the compost
site was not utilized, but the.manure was again stored at
the current compost site location as it was previous to
composting operations, then the total annual access events
would run approximately 13,714 (2,857 out at 35 cy per load
to the storage site, 2,857 empty back to the dairy, 4,000
at 25 cy or ton per load out of storage site, and 4,000
empty back to storage site).
The conclusion is that direct application of manure will
necessitate approximately 8,000 to 14,000 access events per
year.
Please phone me at 303-384-9232 wi h any questions you may
have. _
Sincerely,
ie.‘ rex"

Re: Hwy 66 Composting Facility (USR-1059)
Dear Keith,

I have reviewed the recent letter from Ken Lind dated
August 7, 1995. There are several errors ,and
misrepresentations contained in Mr, Lind's comments. I
believe that to enter into a written debate will serve only
to continue to confuse the real issues, and therefore
choose not to do that. However, I will again attempt to
clarify and respond to the following specific issues_
Historical Volumes Received at the Site:
As I stated in the hearing, the dairy produces an
average of approximately 100,000 cubic yards of manure
and bedding per year. Some years more, some years
less depending on several variable conditions. We
have spent several years observing this.
In the 1993/4 sales year we shipped 69,677 cubic yards
of finished material. This converts to approximately
39,322 tons of finished product assuming an average
weight of 1,100 lbs. per cubic yard- This represents
the amount shipped, not the amount received, As I
stated in the hearing, the manure and bedding brought
to the site decreases in volume approximately 40 - 50%
(not the 60% Mr. Lind suggests). This means that in
1993/4 sales year we received a minimum of 116,128
cubic yards of manure and paper. Beginning and ending
in process inventories, according to our production
manager, where approximately the same.
Site Capacity:
AS I stated in the hearing, the Health Department
requested us to provide them with a volume of finished
material that could be used to estimate the MAXIMUM
POTENTIAL site capacity. We had already stated that
we would not build taw material inventory stock piles,
and that all raw material would quickly be placed in
windrows and processing commenced. My memo Al2.056
states that we project that if the site will hold

approximately 75,000 cubic yards of material in windrows, and
that since each windrow can be completed in approximately 8
weeks if needed, then the site capacity on a THROUGH PUT basis
is 265,909 cubic yards of finished material. We chose to
limit the permitted capacity to 181,818 cubic yards (100,000
tons)., 32% below the sites potential capacity.
Truck Access:
As I stated in the hearing, I have been in contact with
Theresa Jones with the Department of Transportation regarding
truck access issues. I have provided her, and copied your
office with numbers regarding access eventsandcounty mileage
impact.
I have also proposed to her, that we will supply the
Department of Transportation with truck access numbers as part
of our annual report, and that if our access events exceed the
regulatory limits we will meet with the Department of
Transportation and respond accordingly.
Development Standard #3:
Section 2.1, page 18 of out application states that the Weld
County Health Department will be advised in writing of new
material to be composted, and that approval from them must be
received prior to receipt of new materials. I believe this is
adequate. I have conversed with Trevor and he will be
changing his development standard to reflect this language and
also will add some stockpile limitations.
Land Lease:
All information regarding property owners that was required by
your department was supplied. Our agreement wit the
Salazars' is confidential information and will remain so.
While most of this information is redundant, I wanted to again
clarify it. Please notify me of any additional information or
questions you or the Commissioners may require or have.

Re: Hwy 66 Composting Facility
Dear Ms. Jones,
organics
n7 Ov--
In my letter of August 3, 1995 to you, my calculations far
vehicle access impact were based on the manure being hauled
from the dairy to our compost site in 45 cubic yard trucks.
I have since learned that the dairy is currently using a
shorter end dump unit to remove and haul the manure to our
site. T am revising my estimated access events to reflect
a hauling capacity to our site of approximately 35 cubic
yards rather than the 45 cubic yards used in previous
correspondence. This adjustment would equate to an
additional 1,270 total access events per year. The total
estimated access events for composting operations would be
8,158 total for shipped and finished material assuming we
ship a minimum of 60,000 cubic yards of finished material.
I should point out, that in some years we have shipped
around 50,000 cubic yards of finished material which, if
raw product coming into the site were also diminished,
would mean significantly less than 8,000 trips. They go up
and down depending on the dairy.
The point is, that we do not increase the number of trip
events, and in most years we will decrease them. We
significantly reduce the number of miles of County road
usage.
I am also in receipt of a copy of a letter to you dated
August 7, 1995 from Kenneth Lind. While there are several
errors contained in his letter, and many of his conclusions
are based on his opinion, I do not feet it necessary to
become involved in a written debate.
As I have stated several times, the volume of the dairy's
manure will vary depending on several factors. As,I
indicated in my previous correspondence, our experience
with them over the last 5 years has indicated that on an
average, they produce 100,000 cubic yards of manure and
bedding per year. For example, in our 1993/4 sales year
(our fiscal year ends OcUober 1), we shipped 69,677 cubic
yards of finished material, which when converted to raw
material received is 116,128 cubic yards.

I believe I addressed the traffic issues pertaining=to the manure
and bedding generated by the dairy in my August 3rd correspondence
and this letter. It is also our understanding, that until the
access events exceed 120% of the normal events that would:'take
place from dairy operations we would not fall under your
jurisdiction for re-evaluation.
I would propose that as part of our annual report, we notify you of
our total access events. When our total annual access events
exceed the normal dairy operational access events by the 20% limit
per your regulations, we would meet and respond accordingly. We
are required to submit an annual report to the state, and could
calculate truck trip information from it.
By following this procedure, if expansion of the materials
processed at the site cause us to exceed that limit, we would then
fall under your jurisdiction for re-evaluation.
Should you have any additional questions, please don't hesitate to
phone me. My number is (303) 384-9232.

If the site is completely covered with windrows, it will hold
approximately 75,000 cubic yards of material. If each windrow is
cycled every 8 weeks, the total operating capacity of the site
would be 487,500 cubic yards per year {approximately 146,250 tons
of finished material}_ We have chosen to project the sites
capacity at 100,000 finished tons per year as a conservative
figure.
Also, the information on Windrow size is located on page 19,

Supplemental Closure Plan, Odor, and Fly Control Information
A-1 Organics
Highway 66 Composting Facility
March 24, 1995
Closure: In the event that receipt, processing or sales of
materials ceases for a period of more than one year, a notice of
closure shall be submitted in writing to Weld County. All
materials, structures and berm's shall be removed within 180 days
of the notice of closure, or as provided for in an approved closure
plan submitted and agreed to by Weld County. The closure plan
shall demonstrate the following:
1. All finished or unfinished compost materials shall be removed
from the site.
2. Unfinished compost containing regulated materials such as
sewage biosolids, will be disposed of at an approved land fill
site, or properly applied to permitted farm ground.
3. Finished compost materials (including those having met
requirements for unrestricted use) can be used on the site as soil
amendments in amounts deemed necessary by Weld County for
reclamation of the site. The intent is to use finished compost to
aid in reclamation of the facility, but not use the facility for
permanent storage of finished compost.
4. All fencing, structures (other than those originally at the
site), and berm's shall be removed from the site.
5. All disturbed areas shall be seeded and mulched in accordance
with recommendations of the Soil Conservation Service within an
additional 30 day period.
6. The facility will be reclaimed to its original condition and
use, including re -vegetation of ground if required.
Odors: Immediate blending of the materials and repeated aeration
shall be conducted to mitigate odor problems. Odors which
originate at the composting facility and are measured at the
nearest neighboring populated area will not exceed current or
future limits as defined by Colorado Air Quality Control
Commission, Regulation No. 2, ODOR EMISSION REGULATIONS. If an
odor violation occurs that can be shown to have originated at the
compost facility, the Weld County Department of Health shall direct
the operator to correct the problem. The operator may use any
acceptable method or combination of methods to mitigate an odor
problem including, but not limited to bio-filtration, application
of organic odor control agents, additional aeration, and or changes
in operational parameters such as the time of day when mixing or
aeration is accomplished.

Vermin/Fly Control:
Frequent aeration of compost material has been proven to discourage
nesting and eradicate fly larvae. Heat and activity also
discourages burrowing vermin. Experience has shown that composting
actually eliminates fly's. However, should fly's from nearby
feedlots and or dairy's migrate to the site and present an abnormal
nuisance condition, the site will be sprayed with the then current
fly control substance used by Aurora Dairy Corporation or other
material approved by the Weld County Health Department.
