Review activity occurs.
Reclamation procedures include compliance with the Colorado Confined Animal Feeding Control
Regulations to manage solid manure and stormwater runoff until all material is adequately
removed. Should the facility be permanently discontinued for use as a dairy, it would be
marketed under applicable county planning and zoning regulations to its greatest and best use.
8. Explain how the storm water drainage will be handled on the site.
Storm water drainage is handled by a series of storage ponds designed, maintained and
operated in accordance with the Colorado Confined Animal Feeding Control Regulations. Water
from these ponds is used to irrigate farmground. Specific details regarding stormwater
management are outlined in the Confined Animal Feeding Operations Permit(CAFO).
9. Explain how long it will take to construct this site and when construction and
landscaping is scheduled to begin.
This site is currently constructed and operational as a permitted dairy. The proposed addition of
the hospital parlor will begin immediately upon approval of this application and mylar plat
recording.
10. Explain where storage and/or stockpile of wastes will occur on this site.
Solid manure is stored seasonally at the site. Manure is managed and composted and once
composting is complete the materials is removed to an offsite location and sold. Stormwater and
water from the milking facilities is stored in earthen structures designed to meet the requirements
of the Colorado Confined Animal Feeding Operations Control Regulations. Stormwater and
dairy wastewater will be collected for application to farmground at agronomic rates.

AGPRO■LANDPRO 02.23.2005
Site Description
Facility
Front Range Dairy is an existing dairy facility on the north side of Weld County Road 16
between Weld County Roads 19 and 21. Dairy construction is industry-typical pipe and cable
fence, concrete feed aprons and feed bunks, feed alleys and cow movement alleys, feed storage
areas and associated storage structures and maintenance facilities, waste management and control
structures. Front Range Dairy is expanding and the ultimate maximum capacity at will be 4,000
head including approximately 2,000 milk cows and 500 dry cows, with the balance made up of
heifers and calves. Cattle numbers fluctuate throughout the year as calves are born, and cattle
are bought and sold. However, the average number of cattle at the facility is expected to be
approximately 4,000 head. Farm ground surrounds the facility.
Maps
The maps described below are included in Appendix A.

Stormwater and Process Wastewater Management
Surface Runoff
Front Range Dairy will control stormwater with grading, stormwater ponds, and several process
wastewater ponds that will also contain stormwater (see Site Layout Maps in Appendix A).
Front Range Dairy will monitor the site and maintain appropriate diversion structures to ensure
runoff enters the various stormwater collection systems.
25 year, 24-hour Storm
The 25-year, 24-hour storm event for the area west of Fort Lupton, Colorado is 4.0 inches.
Using the SCS runoff curve number 90 for un-surfaced lots and 97 for paved areas, the following
table was generated:

The 10-year, 10-day storm and pond capacity calculations are located in Appendix B.
Surface Runoff Management
Front Range Dairy will maintain the pond systems to contain a 10-year, 10-day storm event.
Should stormwater or process wastewater elevate the ponds beyond their capacity to contain the
appropriate storm, the ponds will be dewatered within 15 days to achieve the required retention
capacity as outlined in the state's regulations. Pumping to surrounding farm ground dewaters the
ponds. Front Range Dairy has approximately 105 acres of farm ground available for
stormwater/process wastewater application. The land application area is on the west and south
sides adjacent to the dairy.
Process Wastewater
Front Range Dairy generates process wastewater within the milking parlor. It is estimated that
Front Range Dairy will generate a maximum of 4,400 gallons of process wastewater per day at
maximum capacity. A table summarizes the process wastewater in Appendix B. Dairy parlor
floors and walls, milking equipment,pipelines, and tanks are washed with fresh water. Process
wastewater flows via pipeline to the south and into the main pond system, which includes a pair
of earthen settling basins, a primary pond, and several secondary ponds where it is available for
land application.
Front Range Dairy Comprehensive Manure&Wastewater Management Plan 5
AGPRO■LANDPRO 02.23.2005
Pumping to surrounding farm ground dewaters the ponds. Front Range Dairy has approximately
80 acres of dry land farm ground available for stormwater/process wastewater application. The
land application area is on the west and south sides adjacent to the dairy.
Ground Water Protection
The existing ponds have been lined and tested to meet the state's seepage requirements. New
ponds will also be constructed to meet the state's maximum seepage requirement. If suitable
clay is found on, or near the site, Front Range Dairy will utilize it for liner material. The clay
will be tested before use to determine suitability and compaction requirements. During
construction, on-site testing will be performed to ensure that compaction and placement are
being performed correctly. Final certification will be done by a licensed professional engineer.
If suitable earthen material is unavailable, Front Range Dairy has the option of using several
synthetic or geo-membrane materials. Any of these materials would be placed utilizing the
manufacturer's guidelines and instructions. Applicable QC/QA will be followed and recorded
during installation. Certification of lining will be kept on site.
Pond Levels
The existing ponds have appropriate pond-level gauges installed. New ponds will also have
pond-level gauges installed when built. The gauges will show incremental depths as well as the
appropriate level to maintain capacity for a chronic storm event.
Floodplains
AGPROfessionals, LLC, has reviewed the Morgan County FIRM maps and determined that
Front Range Dairy is not located within a mapped 100-year floodplain (see the Floodplain Map
in Appendix A).
Land Application of Stormwater/Process Wastewater
Stormwater/process wastewater will be pumped from the ponds onto farm ground in accordance
with the Colorado CAFO regulations, "tier two" land application requirements. Front Range
Dairy will have, on site, adequate pumping equipment to dewater the ponds. They can utilize a
PTO-driven pump, a floatable pumping system, or an installed permanent pumping system. The
application area for stormwater/process wastewater is approximately 105 acres of farm ground
located on the west and south sides and adjacent to the dairy.
During stormwater/process wastewater application, Front Range Dairy will monitor the process
so that runoff does not occur. Front Range Dairy will utilize tail water structures at the bottom
of any flood-irrigated fields during application of stormwater/process wastewater via flood
irrigation. Front Range Dairy does not apply stormwater/process wastewater on frozen ground
or during rainfall events.
Average Years' Stormwater/Process Wastewater Application
Five-year stormwater/process wastewater generation tables (water balance tables) can be found
in Appendix B. The tables estimate the average annual amount of stormwater/process
wastewater to be land applied from the pond system. The tables estimate land application
amounts by maintaining capacity in excess of a 10-year, 10-day storm. The tables account for
the following:
• Average monthly precipitation values from local weather data
• Average monthly lake-evaporation data from local weather data
Front Range Dairy Comprehensive Manure&Wastewater Management Plan 6
AGPRO■LANDPRO 02.23.2005
• Process wastewater generation rate of 4,400 GPD
• Evaporation area equal to surface area of settling basins full, other ponds at appropriate level
• Total drainage area of 73.3 acres
• Runoff percentage from NRCS National Engineering Handbook
• Trial-and-error pumping amounts to maintain capacity in excess of a chronic storm
The calculation tables show that annual land application of approximately 11.0 acre-feet of
stormwater/process wastewater will maintain capacity for the appropriate storm.
Table 3 below shows the land necessary to utilize the nutrients from average years' pumping
requirements in accordance with tier two of the state CAFO regulations. The nitrogen content
and losses are based on Colorado State Cooperative Extension Bulletin No. 568A, Best
Management Practices for Manure Utilization. The calculation in Table 3 indicates that Front
Range Dairy requires approximately 59 acres of brome or orchard grass to utilize the nitrogen
contained in average years' stormwater/process wastewater.

Sustainability
Note that the above calculations show organic nitrogen mineralization and residual accumulation
when stormwater/process wastewater occurs on the same fields every year. The calculations
utilize an equilibrium mineralization rate for organic nitrogen of 42 percent. This represents the
cumulative organic nitrogen released over three years. The previous table indicates that Front
Range Dairy has enough available land (105 acres) to assimilate nutrients produced in
stormwater/process wastewater year after year.
Solid Manure Management
Front Range Dairy manages solid manure through routine pen cleaning and maintenance. Pen
density is managed to optimize the surface area and keep cows clean while maintaining solid, dry
footing for livestock. Front Range Dairy cleans outside pens at least annually. Manure is
removed and composted and/or given away to area farmers for utilization on their lands.
Stockpiling and/or composting area is noted on the Site Layout Map in Appendix A.

Land Application of Solid Manure
Front Range Dairy does not plan to apply solid manure to its own land. They plan to give solid
manure and/or compost away to area farmers for use on the farmers' land.
Nutrient Utilization
Nitrogen is the element that most often limits plant growth. Nitrogen is naturally abundant.
However, it is the nutrient most frequently limiting crop production because the plant available
forms of nitrogen in the soil are constantly undergoing transformation. Crops remove more
nitrogen than any other nutrient from the soil. The limitation is not related to the total amount of
nitrogen available but the form the crop can use. Most nitrogen in plants is in the organic form
and is incorporated into amino acids. By weight, nitrogen makes up from 1 to 4 percent of
harvested plant material.
Essentially all of the nitrogen absorbed from the soil by plant roots is in the inorganic form of
either nitrate or ammonium. Generally, young plants absorb more ammonium than nitrate; as the
plant ages the reverse is true. Under favorable conditions for plant growth, soil microorganisms
generally convert ammonium to nitrate, so nitrates generally are more abundant when growing
conditions are most favorable.
Manure and stormwater/process wastewater is most typically applied for fertilizers and soil
amendments to produce crops. Generally, manure and stormwater/process wastewater is applied
to crops that are most responsive to nitrogen inputs.
The primary objective of applying agricultural by-products to land is to recycle part of the plant
nutrients contained in the by-product material into harvestable plant forage or dry matter.
Another major objective in returning wastes to the land is enhancing the receiving soil's organic
matter content. As soils are cultivated, the organic matter in the soil decreases. Throughout
several years of continuous cultivation in which crop residue returns are low, organic matter
content in most soil decreases dramatically. This greatly decreases the soil's ability to hold
essential plant nutrients.
Land application of Front Range Dairy's stormwater/process wastewater to recycle valuable
nutrients is a practical, commonly accepted best management practice given that fertilization
Front Range Dairy Comprehensive Manure&Wastewater Management Plan 8
AGPROM LANDPRO 02.23.2005
rates are applicable and that deep soil leaching does not occur. Reference material from
Colorado State University is included in Appendix C of this CMWMP for use by the operator in
making sound decisions pertaining to the land application of stormwater/process wastewater.
Soil Testing
The purpose of soil sampling is to ensure that the quantity of nutrients later applied to the soil
will not lead to undesirable nutrient levels in the soil. Knowledge of nitrogen and other nutrients
present in the soil combined with specific crops and realistic yield goals, are key for calculating
appropriate manure and/or stormwater/process wastewater application rates.
Front Range Dairy will test soil on land application areas annually using protocol in Appendix D.
Irrigation Water Testing
Front Range Dairy will test irrigation water, if applicable, at least once per year using the
protocol in Appendix D.
Manure and Stormwater/Process Wastewater Testing
Manure and stormwater/process wastewater testing are essential components of a complete
nutrient balance. The amount of nutrients in solid and liquid waste determines the amount that
can be land applied agronomically.
Front Range Dairy will test stormwater/process wastewater and solid manure at least once per
year following the protocol in Appendix D.
Agronomic Calculations
Agronomic rate is the rate at which plants will utilize nutrients while limiting the amount of
nutrients that are lost via percolation through the soil or runoff. Front Range Dairy will perform
agronomic calculations for every field upon which stormwater/process wastewater is applied.
Agronomic calculations take into account:
• The crop to be grown • Nitrogen content in irrigation water
• A realistic yield goal • Nitrogen credit from previous legume crop;
• Total nitrogen required to meet the yield and
goal • Plant available nitrogen(PAN) in the
• Residual soil nitrate stormwater/process wastewater
• Soil organic matter
Forms for performing agronomic calculation are in Appendix E. One agronomic calculation
sheet is used for each field on which stormwater/process wastewater is applied. In addition,
reference materials from Colorado State Cooperative Extension is located in Appendix C, which
includes nitrogen requirement information for corn, wheat and other crops commonly grown in
Colorado.

Inspection and Testing Schedule
Regular inspections are necessary to ensure wastewater retention structures, and other
associated equipment and structures, are in good working order. Inspection logs should
be filled out monthly for wastewater retention structures and quarterly for machinery and
equipment related to environmental management, such as pump motors. A designated
person will conduct the inspections. Appropriate corrective actions will be taken
immediately and properly documented on the form. Inspection logs will be reviewed
periodically to make sure they are being completed.
Inspection should be conducted as follows:
Monthly: Wastewater Retention Structures
Quarterly: Preventative Maintenance
As Needed: Rainfall Log
Testing should be conducted as follows:
Wastewater— every time wastewater is land applied, minimally annually and within a 60
day period prior to being land applied.
Solid Manure — at least once per year and within a 60 day period prior to being land
applied.
Compost— once per year
Soil (land application areas) — at least once per year and within 4 months prior to
manure or process water application.
Irrigation water—at least once per year

Wastewater Testing Protocol
Testing the nutrient content of wastewater is necessary to ensure that a complete
nutrient balance is being achieved on fields receiving wastewater. The amount of
nutrients in wastewater determines the amount that can be land applied safely. The
laboratory will supply manure sample containers. Solid manure containers will be plastic
bags, and liquid manure containers will be plastic bottles.
Wastewater Collection, Storage and Shipping Procedures
Test wastewater each time that it is applied. Test each wastewater pond that is going
to be de-watered. In order to get the most representative sample, use the following
guidelines when sampling wastewater:
• Collect 1-2 sub-sample from each of the four sides of the wastewater pond and
pour the samples into a clean bucket.
• Collect the sub-samples from a depth of at least 12", and preferably 18", below
the surface.
• Mix the wastewater in the bucket.
• Pour the wastewater sample in a clean bottle provided by the laboratory. Fill the
bottle completely, with no air space (if air space is allowed, then some of the
ammonium will volatilize and the test will not be accurate).
• Using a permanent marker or pen, mark on the sample bottle the date, sample
identification and samplers name.
• Fill out an information sheet and send with the samples.
• Place the composite sample and the information sheet in a cooler, along with
some ice packs to keep the sample cool during shipping. Put the color in a box
or wrap it securely to be sure the lid won't come off during shipping. Mail the
sample as soon as possible so that the order will arrive within 48 hours of the
time the sample was taken. They should not arrive at the lab on a weekend.
• If the samples will not arrive at the laboratory within 48 hours, then they should
be frozen and shipped so they arrive at the laboratory in the frozen condition.
Wastewater samples should be tested for the following parameters, at a minimum:
PH Total Kjeldahl Nitrogen (TKN) Ammonium-N
Soluble Salts Phosphorus (P) Potassium (K)
Note: Place returned laboratory results in LAB RESULTS section.

Solid Manure/Compost Testing Protocol
Manure testing is an essential component of a complete nutrient balance. The amount
of nutrients in manure determines the amount that can be land applied safely. The
laboratory will supply manure sample containers. Solid manure containers will be plastic
bags, and liquid manure containers will be plastic bottles.
Solid Manure Collection, Storage and Shipping Procedures
Test solid manure at least once per year. Give copies of the lab analysis results to the
receiver of the manure, regardless of whether the manure is given away or sold. In
order to get the most representative sample, use the following guidelines when sampling
solid manure:
• Choose a qualified laboratory and use the same one year after year (preferably,
the same lab used for liquid manure and soils).
• Take at least 8 sub-samples from different areas of the feedlot. Be sure the
samples are fairly dry or in the condition they will be in at spreading time.
• The sub-samples should weigh about two pounds each. Place them in a plastic
bucket and mix thoroughly.
• After mixing thoroughly, take one composite sample. The composite should
weigh about one pound.
• Put the composite sample in a plastic bag and seal the bag.
• Using a permanent marker or pen, write on the sample bag the date, sample
identification and sampler's name.
• Fill out an information sheet for each composite sample.
• Place the composite sample and the information sheet in a cooler, along with
some ice packs to keep the sample cool during shipping. Put the cooler in a box
or wrap it securely to be sure the lid won't come off during shipping. Try to ship
as soon as possible so that the order will arrive within 48 hours of the time the
sample was taken. They should not arrive at the lab on a weekend.
• If the samples will not arrive at the laboratory within 48 hours, freeze them, and
ship them so that they arrive at the laboratory in the frozen condition.
Solid manure needs to be tested for the following parameters, at a minimum:
Percent moisture Total Kjeldahl Nitrogen (TKN) Ammonium-N
Soluble Salts Phosphorus (P) Potassium (K)

Soil Testing Protocol
The purpose of soil sampling is to make sure the amount of nutrients later applied to the
soil will not lead to excessive nutrient levels in the soil. Three pieces of information are
needed to determine this: (1) The amount of nitrogen and other nutrients present in the
soil, (2) the specific crop to be grown, and (3) a realistic yield goal for the crop. With
knowledge of these three components, you can determine the appropriate amount of
manure to apply to a field.
Soil Sample Collection, Storage and Shipping Procedures
The laboratory will typically supply field information sheets, soil sample containers, as
well as the proper instructions. In the absence of laboratory-supplied sample bags, use
clean plastic bags.
Routine soil sampling should be done within 4 month of having manure or wastewater
applied, and to fields that had manure applied the previous year.
In order to get the most representative sample, use the following guidelines:
• Use a soil probe, soil auger, spade or garden trowel to collect the samples.
Collect separate samples in the 0-12" and in the 12-24" horizons. Collect soil in
a plastic bucket or paper container to prevent contamination with zinc and other
micronutrients.
• Take 15-20 sub-samples across each land management unit, and per uniform
soil type within each land management unit. For fields les than 40 acres, collect
at least 10 cores to form the composite sample. Follow and "X" or "Z" sampling
pattern across the field. Place the first horizon in a separate bucket from the
second horizon.
• A land management unit is an area under a center pivot or a tract of land on
which similar management practices are used (including crop to be grown). It
shall not exceed 160 acres.
• After thoroughly mixing the sub-samples, take one composite sample.
• The composite soil sample from each management unit and each horizon depth
should be placed in its own sample bag.
• Each sample bag should be marked with the date, sample identification and
samplers name, i.e. AgPro Dairy, 11/7/00, Field #1, 0-12".
• Fill out a field information sheet and send it with the samples.
• Keep the soil samples cool and dry, and send them to the laboratory
immediately. If samples cannot be sent to the laboratory immediately, allow the
soil to air dry on a sheet of newspaper for 24-48 hours before placing in a sample
bag. Keep samples away from high temperatures, such as those found on the
dashboard of a pickup.
0-12" soil samples need to be tested for the following parameters at a minimum:
Nitrate-N Organic Matter pH
Phosphorus (P) Potassium (K) Ammonium-N
12-24" soil samples should be tested for nitrate-N
Note: Place returned laboratory results in LAB RESULTS section of this notebook.

Irrigation Water Testing Protocol
Irrigation water can contain significant amounts of nitrate, which will contribute to crop
growth. This nitrate should be factored into the overall nutrient budget for the crop.
Sterile bottles should be used and can be obtained from the laboratory.
Water collection, storage, and shipping procedures
• Irrigation wells should be sampled at the peak of the irrigation season. Ditches
can also be sampled, but they will be much more variable in nutrient content and
should be sampled several times, with the values averaged together.
• If the well is not currently running, allow it to run for 5-10 minutes. It should not
have been off for more than a day.
• Fill the sample bottle to the indicated mark. Identify the container with the farm
name, sample name, date and time of sampling.
• Fill out the information sheet provided by the laboratory.
• Keep the sample cool and send it to the laboratory immediately after collection,
and by the fastest method available. Nitrate must be tested within 48 hours after
sampling. The sample should arrive at the lab no later than on a Thursday to
allow time for testing.
• Irrigation water may be tested for nitrate-N, sulfate, soluble salts, and other
minerals.
Irrigation water needs to be tested for the following parameters, at a minimum:
Nitrate-N

Introduction
This supplemental Management Plan for Nuisance Control has been developed and implemented
to identify methods Front Range Dairy, will use to minimize the inherent conditions that exist in
confinement feeding operations. This supplement outlines management practices generally
acceptable and proven effective at minimizing nuisance conditions. Neither nuisance
management nor this supplemental plan is required by Colorado State statute or specifically
outlined in the Colorado Confined Animal Feeding Operations Control Regulations. This is a
proactive measure to assist integration into local communities. These management and control
practices, to their best and practical extent, will be used by Front Range Dairy.

Air Quality
Air quality at and around confined animal feeding operations are affected primarily from the
relationship of soil/manure and available moisture. The two primary air quality concerns at
dairies are dust and odor. However,the management practices for dust or odor control are not
inherently compatible. Wet pens and manure produce odor. Dry pens are dusty. The two
paragraphs below outline the best management practices for the control of dust and odors that
Front Range Dairy will use. The manager shall closely observe pen conditions and attempt to
achieve a balance between proper dust and odor control.
Dust
Dust from pen surfaces is usually controlled by intensive management of the pen surface by
routine cleaning and harrowing of the pen surface. The purpose of intensive surface
management is twofold; to keep cattle clean and to reduce pest habitat. The best management
systems for dust control involve moisture management. Management methods Front Range
Dairy shall use to control dust are:
1. Pen density
Moisture will be managed by varying stocking rates and pen densities. The animals wet
manure and urine keep the surface moist and control dust emissions. Stocking rates in
new portions of the facility will be managed to minimize dust.
2. Regular manure removal
Front Range Dairy will continue to conduct regular manure removal. Manure removal
and pen maintenance will be conducted as needed.
3. Sprinkler systems
Sprinkler systems, timed appropriately, are an effective method for keeping Feedlot
surfaces moist. Feedlot cattle produce significant moisture through urine and feces. Pens
surfaces are extensively maintained for cattle health.
4. Water Trucks
Should nuisance dust conditions arise, water tanker trucks or portable sprinkling systems
may be used for moisture control on pens and roadways to minimize nuisance dust
conditions.
Odor
Odors result from the natural decomposition processes that start as soon as the manure is
excreted and continue as long as any usable material remains as food for microorganisms living
everywhere in soil, water and the manure. Odor strength depends on the kind of manure, and the
conditions under which it decomposes. Although occasionally unpleasant, the odors are not
dangerous to health in the quantities customarily notices around animal feeding operations and
fields where manure is spread for fertilizer.
3
Front Range Dairy
AGPROfessionals,LLC
Front Range Dairy will use the methods and management practices listed below for odor control:
1. Establish good pen drainage
Dry manure is less odorous than moist manure. The feedlot will conduct routine pen
cleaning and surface harrowing to reduce standing water and dry or remove wet manure.
2. Regular manure removal
Reduce the overall quantity of odor producing sources. The feedlot will conduct routine
pen cleaning and harrowing several times per month.
3. Reduce standing water
Standing water can increase microbial digestion and odor producing by-products. Proper
pen maintenance and surface grading will be conducted by the feedlot to reduce standing
water.
The stormwater ponds will be dewatered regularly in accordance with the Manure and
Wastewater Management Plan for Front Range Dairy. No chemical additives or
treatments of the stormwater ponds for odor control are planned. Research to date
indicates poor efficacy, if any, of these products.
4. Land application timing
Typically air rises in the morning and sinks in the evening. Front Range Dairy will
consider weather conditions and prevailing wind direction to minimize odors from land
application.
If it is determined that nuisance dust and odor conditions persist, Front Range Dairy may
increase the frequency of the respective management practices previously outline such as pen
cleaning, surface grading and pen maintenance. Additionally, if nuisance conditions continue to
persist beyond increased maintenance interval controls, Front Range Dairy will install physical
or mechanical means such as living windbreaks and/or solid fences to further minimize nuisance
conditions from dust and odors.
Insects and rodents inhabit areas that 1) have an adequate to good food supply and 2) foster
habitat prime for breeding and living. Key practices Front Range Dairy will use to manage
insects and rodents are to first eliminate possible habitat and then reduce the available food
supply.
Front Range Dairy will control flies by:
Pest Control
Insects and Rodents
1. Regular manure removal
Manure management removes both food sources and habitat
4
Front Range Dairy
AGPROfessionals, LLC
2. Reduce standing water
Standing water is a primary breeding ground for insects
3. Minimize fly habitat
Standing water, weeds and grass, manure stockpiles, etc., are all prime habitat for
reproduction and protection. Reduce or eliminate these areas where practical.
4. Weeds and grass management
Keep weeds and grassy areas to a minimum. These provide both protection and breeding
areas.
5. Minimize stockpiles or storage of manure
Stockpiles of manure provide both breeding and protective habitat. Keep stockpile use to
a minimum.
6. Biological treatments
Parasitic wasps are excellent biological fly control and are widely used. The wasps lay
their eggs in fly larvae hindering fly reproduction.
7. Baits and chemical treatments
Due to environmental and worker's safety concerns, chemical treatments are a last line of
defense for insect control. Baits and treatments must be applied routinely. However,
they are very effective.
Rodent control at Front Range Dairy is best achieved by minimizing spillage of feedstuffs
around the operation. Good housekeeping practices and regular feedbunk cleaning, site grading
and maintenance are used to reduce feed sources. Rodent traps and chemical treatments are
effective control methods and will be used as necessary.
In the event it is determines nuisance conditions from pest such as flies and rodents persist,
Front Range Dairy will initially increase the frequency of the housekeeping and management
practices outlines previously. If further action is necessary, Front Range Dairy will increase use
of chemical controls and treatments, such as fly sprays and baits and Rodendicide for pest
control.
