NUTRIENT UTILIZATION PLAN
Owner(s):
Murphy -Brown, LLC
Facility Name:
Register Trailer Wash Facility; W00014247
County:
Duplin
Facility Type:
Truckwash
Storage Structure:
Anaerobic Lagoon
Storage Period:
>180
Application Method:
Irrigation
The wastewater from your facility must be land applied at a specified rate to prevent pollution
of surface water and/or groundwater. The plant nutrients in the wastewater should be used to
reduce the amount of commercial fertilizer required for the crops in the fields where the waste
water is to be applied.
This nutrient utilization plan uses nitrogen as the limiting nutrient. Wastewater 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 nutrient utilization plan in order to maximize
the fertilizer value of the wastewater and to ensure that it is applied in an environmentally safe
manner. These factors are to be used as guidance.
1. Always apply wastewater based on the needs of the crop to be grown and the
nutrient content of the wastewater. Do not apply more nitrogen than the crop can utilize.
2. Soil types are important as they have different infiltration rates, leaching potentials,
cation exchange capacities, and available water holding capacities.
3. Normally waste shall be applied to land eroding at less than 5 tons per acre per
year. Waste may be applied to land eroding at 5 or more tons per acre annually, but
less than 10 tons per acre per year providing that adequate filter strips are established.
4. 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 DWQ regulations.
5. Wind conditions should also be considered to avoid drift and downwind odor
problems.
6. 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 not more than
30 days prior to planting a crop or forages breaking dormancy. Injecting the waste or
disking will conserve nutrients and reduce odor problems.

This plan is based on the wastewater application method shown above. If you choose to change
methods in the future, you need to revise this plan. Nutrient levels for different application
methods are not the same.
The estimated acres needed to apply the wastewater is based on typical nutrient content
for this type of facility. In some cases you may want to have plant analysis made, which could
allow additional wastewater to be applied. Provisions shall be made for the area receiving the
wastewater to be flexible so as to accommodate changing wastewater analysis content and crop
type. Lime must be applied to maintain pH in the optimum range for specific crop production.
AMOUNT OF PLANT AVAILABLE NITROGEN PRODUCED PER YEAR (Ibs):

This plan does not include commercial fertilizer. The facility should produce adequate plant
available nitrogen to satisfy the requirements of the crops listed above.
The applicator is cautioned that P and K may be over applied while meeting the N requirements.
In the future, regulations may require these facilities to have a nutrient management plan that
addresses all nutrients. This plan only addresses nitrogen.
In interplanted fields ( i.e. small grain, etc, interseeded in bermuda), forage must be removed
through grazing, hay, and/or silage. Where grazing, plants should be grazed when they
reach a height of six to nine inches. Cattle should be removed when plants are grazed to a
height of four inches. In fields where small grain, etc, is to be removed for hay or silage, care
should be exercised not to let small grain reach maturity, especially late in the season (i.e.
April or May). Shading may result if small grain gets too high and this will definitely interfere
with stand of bermudagrass. This loss of stand will result in reduced yields and less nitrogen
being utilized. Rather than cutting small grain for hay or silage just before heading as is
the normal situation, you are encouraged to cut the small grain earlier. You may want to
consider harvesting hay or silage two to three times during the season, depending on the
time small grain is planted in the fall.
The ideal time to interplant small grain, etc, is late September or early October. Drilling is
recommended over broadcasting. Bermudagrass should be grazed or cut to a height of
about two inches before drilling for best results.

The nutrient utilization plan must contain provisions for periodic land application of sludge/grit at
agronomic rates. The sludge/grit will be nutrient rich and will require precautionary measures to
prevent over application of nutrients or other elements. Your wastewater facility will produce
approximately 0 pounds of plant available nitrogen per year will in the lagoon
sludge/grit based on the rates of accumulation listed above.
If you remove the sludge/grit every 5 years, you will have approximately 0 pounds of plant
available nitrogen to utilize. Assuming you apply this PAN to hybrid bermuda grass hayland at the
rate of 300 pounds of nitrogen per acre, you will need 0 acres of land. If you apply this PAN
to corn at a rate of 125 pounds per acre, you will need 0 acres of land. Please note that
these are only estimates of the PAN produced and the land required to utilize that PAN. Actual values
may only be determined by sampling the sludge/grit for plant available nitrogen content prior to application
Actual utilization rates will vary with soil type, crop, and realistic yield expectations for the specific
application fields designated for sludge/grit application at time of removal.
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.
If surface irrigation is the method of land application for this plan, it is the responsibility of the
producer and irrigation designer to ensure that an irrigation system is installed to properly
irrigate the acres shown in the preceding table. Failure to apply the recommended rates and
amounts of nitrogen shown in the tables may make this plan invalid.
*This is the maximum application amount allowed for the soil assuming the amount
of nitrogen allowed for the crop is not over applied. In many situations, the application
amount shown cannot be applied because of the nitrogen limitation. The maximum
application amount shown can be applied under optimum soil conditions.
Your facility is designed for Duplin of temporary storage and the temporary storage must
be removed on the average of once every 4 months. In no instance should the volume of the
wastewater stored in your structure be within the 25 year 24 hour storm storage or two feet of
freeboard except in the event of the 25 year 24 hour storm.
It is the responsibility of the producer and wastewater applicator to ensure that the application
equipment is operated properly to apply the correct rates to the acres shown in the tables. Failure
to apply the recommended rates and amounts of nitrogen shown in the tables may make this plan
invalid.
Call your technical specialist after you receive the wastewater analysis report for assistance in
determining the amount of wastewater per acre to apply to achieve the proper application amount
prior to applying the wastewater.

Additional Comments:
Fields 1 & 2 are in Combination Bermudaarass which means that at least
half of the crop will be harvested as hay and the other half harvested by grazing.
Both fields will be overseeded with a small grain and may be harvested as hay
or by grazinq.
Field 3 is in a corn/soybean/small grain rotation. Residual N from soybeans
has been deducted from the corn rate. The small grain qrain will be harvested
by grazing.
11/9/2021 NUP revised to change fields 1 & 2 from combonation graze/hay
to graze. Corn and Soybean rates were updated. No other changes have
been made.
5/10/2023 Updated plan to allow the option for the bermudagrass to be
harvested as hay if desired. If this option is utilized, use the application rates
listed for hay. No other changes have been made.
