SUBCHAPTER BCONCENTRATED ANIMAL FEEDING OPERATIONS
RULE §321.47Requirements for Animal Feeding Operations (AFOs) Not Defined or Designated As Concentrated Animal Feeding Operations (CAFOs)

    (C) Utilize the results of these analyses in determining application rates for manure, sludge, and wastewater.

  (2) Annual sampling. The operator shall:

    (A) collect and analyze at least one representative sample of manure, sludge (if applicable), and wastewater, for total nitrogen, total phosphorus, and total potassium;

    (B) collect and analyze at least one representative soil sample from each LMU where manure, sludge, or wastewater was applied during the preceding year according to the procedures in paragraphs (4) and (5) of this subsection; and

    (C) utilize the results of these analyses in determining application rates for manure, sludge, and wastewater.

  (3) The operator shall make the most recent nutrient analysis available to any recipient of manure, sludge, or wastewater.

  (4) Sampling procedures. The operator shall employ sampling procedures using accepted techniques of soil science for obtaining representative samples and analytical results.

    (A) Samples shall be collected using approved methods described in the agency's guidance RG-408 entitled "Soil Sampling for Concentrated Animal Feeding Operations."

    (B) Samples shall be collected by the operator or its designee and analyzed by a soil testing laboratory annually.

    (C) Obtain one composite sample for each LMU and per uniform soil type (soils with the same characteristics and texture) within the LMU.

    (D) Composite samples shall be comprised of ten to 15 randomly sampled cores at a depth of zero to six inches.

  (5) Laboratory analysis. The operator shall have a laboratory analysis of the soil samples performed for physical and chemical parameters to include: nitrate reported as nitrogen in parts per million (ppm); phosphorus (extractable, ppm, using Mehlich III extractant with Inductively Coupled Plasma (ICP) analysis); potassium (extractable, ppm); sodium (extractable, ppm); magnesium (extractable, ppm); calcium (extractable, ppm); soluble salts (ppm) or electrical conductivity (deciSiemens/meter (dS/m) or millimhos/cm (mmhos/cm) determined from extract of 2:1 volume to volume (v/v) water/soil mixture); and soil water pH (soil:water, 1:2 ratio).

  (6) Soil samples shall be submitted to a soil testing laboratory along with a previous crop history of the site, intended crop use, and yield goal. Soil test reports shall include nutrient recommendations for the crop yield goal.

(h) Nutrient utilization plans (NUPs).

  (1) Manure, sludge, or wastewater shall not be land applied to a LMU, unless the land application is implemented in accordance with a detailed NUP when results of the annual soil analysis for extractable phosphorus indicate:

    (A) a level greater than 200 ppm; or

    (B) a level greater than 350 ppm for an LMU where the average annual rainfall is 25 inches or less, erosion control is adequate to keep erosion at the soil loss tolerance (T) or less, and the closest edge of the field is more than one mile from a named stream; or

    (C) if ordered by the commission to do so in order to protect water in the state.

  (2) An NMP, based on crop removal, certified in accordance with NRCS Practice Standard Code 590 complies with the requirements of a complete and effective NUP.

  (3) A NUP, based on crop removal, shall be developed by an employee of the NRCS, a nutrient management specialist certified by the NRCS, the TSSWCB, Texas AgriLife Extension Service, an agronomist or soil scientist on full-time staff at an accredited university located in the State of Texas, or a professional agronomist or soil scientist certified by the American Registry of Certified Professionals in Agronomy, Crops and Soils, after approval by the executive director based on a determination by the executive director that another person or entity identified in this paragraph cannot develop the plan in a timely manner. No land application under an approved NUP shall cause or contribute to a violation of water quality standards or create a nuisance.

  (4) Land application under the terms of the NUP may begin as soon as the plan is developed in accordance with this subsection. After a NUP has been implemented, the operator shall land apply in accordance with the NUP until soil phosphorus is reduced below 200 ppm. Thereafter, the AFO operator shall apply manure, litter, or wastewater at agronomic rates according to the requirements of this section.

(i) Recordkeeping requirements.

  (1) Records required under this subsection must be kept on site for a minimum of five years from the date the record was created. Any AFO operator that does not use an RCS is not subject to subparagraphs (B) - (D) and (F). Unless otherwise specified, records shall include:

    (A) a list of any significant spills of pollutants with the potential to reach water in the state;

    (B) a schedule for liquid manure removal;

    (C) a date log indicating weekly inspection of wastewater level in the RCS;

    (D) a log of all measurable rainfall events;

    (E) a copy of the results of initial and annual soils, manure, sludge, and wastewater analyses;

    (F) records of dates of inspection of the RCS, and a log of the findings of such inspections;

    (G) the groundwater monitoring plan associated with the use of a playa;

    (H) site-specific documentation that no significant hydrologic connection exists between the wastewater in the RCS and water in the state;

    (I) any written agreement with a landowner which documents the allowance of nighttime application of manure, sludge, or wastewater; and

    (J) a copy of the NUP, if required.

  (2) For facilities where manure, sludge, or wastewater is applied on LMUs, such records shall include the following information:

    (A) the date of manure, sludge, or wastewater application to each field;

    (B) the location of the specific LMU and volume or amount applied during each application event;

    (C) the acreage of each individual crop on which manure, sludge, or wastewater is applied;

    (D) the assumptions for calculating the total amount of nitrogen and phosphorus applied per acre to each field, including sources of nutrients other than manure, sludge, and wastewater on a dry basis;

    (E) the percentage of moisture content of the manure and sludge; and

    (F) the actual annual yield of each harvested crop.

  (3) Where manure, sludge, or wastewater, if applicable, is sold or given to other persons for off-site land application or disposal, the operator must maintain a log of: the date of removal from the AFO; the name and address of the recipient; and the amount, in wet tons, dry tons, or cubic yards, of manure or gallons of wastewater removed from the AFO. (A single pickup load need not be recorded.)

(j) Documentation of liner maintenance. The operator shall have an NRCS engineer, licensed Texas professional engineer, or licensed Texas professional geoscientist review the documentation and conduct a site evaluation every five years.

(k) Groundwater monitoring. In the event that groundwater monitoring is required by §321.41 of this title or required by the executive director, the operator shall annually collect a groundwater sample from each well that provides water for the facility. Each sample shall be analyzed for nitrate as nitrogen and chloride where groundwater monitoring is required by §321.41 of this title and analyzed for nitrate as nitrogen, chloride, and total dissolved solids where groundwater monitoring is required by the executive director. The operator shall use the methods outlined in the groundwater monitoring plan, and compare the analytical results to the baseline data. Data from any required monitoring wells must be submitted to the executive director and kept on site for five years. The first year's sampling shall be considered the baseline data and must be retained on site for the life of the facility, unless otherwise provided by the executive director. If a 10% deviation in concentration of any of the sampled constituents is found, the operator must notify the executive director within 30 days of receiving the analytical results.

(l) Inspections. The AFO operator must conduct the following inspections to assure the facility maintains its efficiency. Records of inspections shall be maintained for a period of five years.
