Additional Description
Sludge will be transported from farms into this location. The sludge may be stored in the lagoon
as an intermediate storage structure prior to transfer into the dry sheds. If this occurs,
minimum freeboard levels according to the lagoon design will be maintained at all times and
excess water will be irrigated on sprayfields on the site according to the farm Nutrient
Utilisation Plan. Records of sludge transfers will be maintained.
This project is located in a sprayfield on the Eastern side of the property. The site will be
levelled off and foundations constructed for the sludge dryers, which are oriented in an E-W
orientation on the site.
This project is exempt from requiring a stormwater permit or erosion control plan. However,
rainwater runoff from the structures will be managed appropriately to prevent damage to the
foundations of the concrete pads. Drainage will be constructed adjacent to each building to
take runoff away, and will be routed to the drainage ditches on the property. Culverts will be
constructed where access roads cross the drainage paths on the end of the building.

Type of Operation :
Wean to Feeder Swine
Number of Animals :
3800 pigs design capacity
Application Method:
Irrigation
The waste from your animal facility must be land applied at a specified rate to prevent
pollution of surface and/or groundwater. The plant nutrients in the animal waste should be
used to reduce the amount of commercial fertilizer required for the crops in the fields where
waste is to be applied. This waste utilization plan uses nitrogen as the limiting nutrient.
Waste should be analyzed before each application cycle. Annual soil tests are strongly
encouraged so that all plant nutrients can be balanced for realistic yields of the crop to be
grown.
Several factors are important in implementing your waste utilization plan in order to maximize
the fertilizer value of the waste and to ensure that it is applied in an environmentally safe
manner. Always apply waste based on the needs of the crop to be grown and the nutrient
contents of the waste. Do not apply more nitrogen than the crop can utilize. Soil types are
important as they have different infiltration rates, leaching potentials, cation exchange
capacities, and avaialable water holding capacities. Normally waste shall not be applied to
land eroding at greater than 5 tons per acre per year. With special pre -cautions, waste may
be applied to land eroding at up to 10 tons per acre per year. Do not apply waste on
saturated soils, when it is raining, or when the surface is frozen. Either of these conditions
may result in runoff to surface waters which is not allowed under DEM regulations. Wind
conditions should also be considered to avoid drift and downwind odor problems. To
maximize the value of the nutrients for crop production and to reduce the potential for
pollution, the waste should be applied to a growing crop or applied to bare ground not more
than 30 days prior to planting. Injecting the waste or disking will conserve nutrients and
reduce odor problems. This plan is based on waste application through irrigation for this is
the manner in which you have chosen to apply your waste. If you choose to inject the waste
in the future, you need to revise this plan. Nutrient levels for injecting waste and irrigating
waste are not the same.
The estimated acres needed to apply the animal waste is based on typical nutrient content for
this type of facility. Acreage requirements should be based on the waste analysis report from
your waste management facility. Attached you will find information on proper sampling
techniques, preparation, and transfer of waste samples to the lab for ananlysis. This waste
utilization plan, if carried out, meets the requirements for compliance with 15A NCAC
2H.0217 adopted by the Environmental Management Commission.
Page 1 of 10

AMOUNT OF WASTE PRODUCED PER YEAR (gallons, ft3, tans, etc.)
3800 pigs X .4 tons waste/pigs/year = 1520 tons
AMOUNT OF PLANT AVAILABLE NITROGEN (PAN) PRODUCED PER YEAR
3800 pigs X .3438 Ibs PAN/pigs/year = 1306.44 PAN/year
Applying the above amount of waste is a big job. You should plan time and have appropriate
equipment to apply the waste in a timely manner.
The following acreage will be needed for waste application based on the crop to be grown,
soil type and suface application.

Acres show in each of the preceeding tables are considered to be the usable acres excluding
required buffers, filter strips along ditches, odd areas unable to be irrigated, and perimeter
areas not receiving full application rates due to equipment limitations. Actual total acres in the
fields listed may, and most likely will be, more than the acres shown in the tables.
NOTE: The Waste Utilization Plan must contain provisions for periodic land application of
sludge at agronomic rates. The sludge will be nurturient rich and will require precautionary
measures to prevent over application of nutrients or other elements. Your production facility
will produce approximately 288.8 pounds of plant available nitrogen (PAN) per year in the
sludge that will need to be removed on a periodic basis. This figure is PAN when
broadcasting the sludge. Please be aware that additional acres of land, as well special
equipment, may be needed when you remove this sludge.
See the attached map showing the fields to be used for the utilization of waste water.
APPLICATION OF WASTE BY IRRIGATION
The irrigation application rate should not exceed the intake rate of the soil at the time of
irrigation such that runoff or ponding occurs. This rate is limited by initial soil moisture
content, soil structure, soil texture, water droplet size, and organic solids. The application
amount should not exceed the available water holding capacity of the soil at the time of
irrigation nor should the plant available nitrogen applied exceed the nitrogen needs of the
crop.
Your facility is designed for 180 days of temporary storage and the temporary storage must
be removed on the average of once every 5.92 months. In no instance should the volume of
waste being stored in your structure be within 1.58 feet of the top of the dike.
If surface irrigation is the method of land application for this plan, it is the responsiblity of the
producer and irrigation designer to ensure that an irrigation system is installed to properly
irrigate the acres shown in Tables 1 and 2. Failure to apply the recommended rates and
amounts of Nitrogen shown in the tables may make this plan invalid.

NARRATIVE OF OPERATION
This farm will not be stocked with animals but there is sufficient land available if it was
stocked. This farm will be used for a centralized greenhouse swine sludge drying operation.
The acreages are based off a Nutrient Utilization Plan written by Kevin Weston on 9/8/2008.
The latest nitrogen co -efficient and RYE tables were used in this plan's devolpment.

PLANS & SPECIFICATIONS
1. Animal waste shall not reach surface waters of the state by runoff, drift, manmade
conveyances, direct application, or direct discharge during operation or land application. Any
discharge of waste which reaches surface water is prohibited. Illegal discharges are subject
to assessment of civil penalties of $10,000 per day by the Division of Water Quality for every
day the discharge continues.
2. The Field Office must have documentation in the design folder that the producer either
owns or has long term access to adequate land to properly dispose of waste. If the producer
does not own adequate land to properly dispose of waste, he shall provide NRCS with a copy
of a written agreement with a landowner who is within a reasonable proximity, allowing
him/her the use of the land for waste application for the life expectancy of the production
facility. It is the responsibility of the owner of the facility to secure an update of the Waste
Utilization Plan when there is a change in the operation, increase in the number of animals,
method of utilization, or available land.
3. Animal waste shall be applied to meet, but not exceed, the Nitrogen needs for realistic crop
yields based on soil type, available moisture, historical data, climate conditions, and level of
management, unless there are regulations that restrict the rate of application for other
nutrients.
4. Animal waste may be applied to land that has a Resource Management System (RMS) or
an Alternative Conservation System (ACS). If an ACS is used the soil loss shall be no greater
than 10 tons per acre per year and appropriate filter strips will be used where runoff leaves
the field. These filter strips will be in addition to 'Buffers" required by DEM. (See FOTG
Stantard 393 - Filter Strips and Standard 390 Interim Riparian Forest Buffers).
5. Odors can be reduced by injecting the waste or disking after waste application. Waste
should not be applied when there is danger of drift from the irrigation field.
6. When animal waste is to be applied on acres subject to flooding, it will be soil incorporated
on conventionally tilled cropland. When applied to conservation tilled crops or grassland, the
waste may be broadcast provided the application does not occur during a season prone to
flooding. (See "Weather and Climate in North Carolina" in the NRCS Technical Reference -
Environment file for guidance.)
*7. Liquid waste shall be applied at rates not to exceed the soil infiltration rate such that
runoff does not occur offsite or to surface waters and in a method which does not cause drift
from the site during application. No ponding should occur in order to control conditions
conducive to odor or flies and to provide uniformity of application.
8. Animal waste shall not be applied to saturated soils, during rainfall events, or when the
surface is frozen.
9. Animal waste shall be applied on actively growing crops in such a manner that the crop is
not covered with waste to a depth that would inhibit growth.
10. Waste nutrients shall not be applied in fall or winter for spring planted crops on soils with
a high potential for leaching. Waste nutrient loading rates on these soils should be held to a
minimum and a suitable winter cover crop planted to take up released nutrients. Waste shall
not be applied more than 30 days prior to planting of a crop on bare soil.
11. Any new swine facility sited on or after October 1, 1995 shall comply with the following:
the outer perimeter of the land area onto which waste is applied from a lagoon that is a
component of a swine farm shall be at least 50 feet from any residential property boundary
and from anv perennial stream or river (other that an irrigation ditch or canal. Animal waste
Page 7 of 10

other than swine waste from facilities sited on or after October 1, 1995), shall not be applied
closer than 25 feet to perennial waters. (See Standard 393 - Filter Strips)
12. Animal waste shall not be applied closer than 100 feet to wells.
13. Animal Waste shall not be applied closer than 200 feet of dwellings other than those
owned by the landownwer.
14. Waste shall be applied in a manner not to reach other property and public right - of ways
15. Animal waste shall not be discharged into surface waters, drainageways, or wetlands by
discharge or by over -spraying. Animal waste may be applied to prior converted croplands
provided they have been approved as a land application site by a "technical specialist'.
Animal waste should not be applied on grassed waterways that discharge directly into water
courses, except when applied at agronomic rates and the application causes no runoff or drift
from the site.
*16. Domestic and industrial waste from washdown facilities, showers, toilets, sinks, etc.,
shall not be discharged into the animal waste management system.
*17. A protective cover of appropriate vegetation will be established on all disturbed areas
(lagoon embankments, berms, pipe runs, etc.). If needed, special vegetation shall be
provided for these areas and shall be fenced, as necessary, to protect the vegetation.
Vegetation such as trees, shrubs, and other woody species, etc. are limited to areas where
considered appropriate. Lagoon areas should be kept mowed and accessible. Lagoon berms
and structures should be inspected regularly for evidence of erosion, leakage or discharge.
*18. If animal production at the facility is to be suspended or terminated, the owner is
responsible for obtaining and implementing a "closure plan" which will eliminate the possibility
of an illegal discharge, pollution and erosion.
*19. Waste handling structures, piping, pumps, reels, etc., should be inspected on a regular
basis to prevent breakdowns, leaks, and spills. A regular maintenance checklist should be
kept on site.
20. Animal waste can be used in a rotation that includes vegetables and other crops for direct
human consumption. However, if animal waste is used on crops for direct human
consumption, it should only be applied as a preemergence with no other applications of
animal waste during the crop season.
*21. Highly visible markers shall be installed to mark the top and bottom elevations of the
temporary storage (pumping volume) of all waste treatment lagoons. Pumping shall be
managed to maintain the liquid level between the markers. A marker will be required to mark
the maximum storage volume fpr waste storage ponds.
22. Waste shall be tested within 60 days of utilization and soil shall be tested at least annually
at crop sites where waste products are applied. Nitrogen shall be the rate -determining
element. Zinc and copper levels in the soils shall be monitored and alternative crop sites
shall be used when these metals approach excessive levels. pH shall be adjusted for
optimum crop production amd maintained. Soil and waste analysis records shall be kept for
five (5) years. Poultry dry waste application records shall be maintained for three (3) years.
Waste application records for all other waste shall be maintained for five (5) years.
23. Dead animals will be disposed of in a manner that meets North Carolina Department of
Agriculture regulations.
