RE: Continuing Notice of Violation Recommendation for Enforcement
Cognac Farms I AWS770019
Anson County (Richmond County)
NOV-2021—PC-0380
Dear Ms. Diane Harrison and Ms. Katie Fontenot:
ovd_D 42l
In response to your letter received November 22, 2021. We respectfully submit the following
information.
Information was submitted via e—mail on September 14, 2021, when it was brought to my
attention the first submission of information was not available to you.
Regarding Violations sited in your letter of November 18, 2021.
Violation 1: Failure to have all waste application equipment tested and calibrated at least once
every two calendar years. Please see Attachment #2, Irrigation Equipment Flow Meter Field
Calibration, dated 03/22/2020.
Violation 2: Failure to have an analysis of representative sample of the animal waste to be applied
shall be conducted in accordance with recommended laboratory sampling procedures as close to
the time of application as practical and at least within sixty (60) days (before or after) the date of
application. Please see test conducted on 02/03/2020 (Attachment #5) and test was completed
07/28/2021 (Attachment #4 and 4-1). We will do more testing from this point forward.
Violation 3: Failure to conduct a survey of the sludge accumulation in all lagoons every year.
Please see (Attachment #3, #3-1, #3-2, #3-3, and #3-4) dated 06/20/2020 — which was over at

Cognac Farms I AWS770019 Page 2
.53 and compliance date of 06/15/2022. Please see (Attachment #6, #6-1, #6-2, and #6-3) dated
10/01/2021— which was at .50, which is in compliance.
Violation 4: Failure to record all irrigation and land application event(s) including hydraulic loading
rates, nutrient loading rates and cropping information. The Permittee shall also record removal of
solids and document nutrient loading rates if disposed of on —site or record the off —site location(s).
Noted during visit, IRR2 reports through 05/29/2021 were available. We had not pumped from
05/29/2021 through 07/31/2021 due to lagoon level at 27" (May, 2021) and 24" at the end of July,
2021. We also had equipment repair problems, and trouble acquiring parts during this time period.
Violation 5: Failure of removing crops. We did not cut the grasses due to labor shortage and
repairs unavailable due to the pandemic. The grasses were cut 08/2021.
Violation 6: Failure of permit Section II 14. Lagoon/storage pond shall be kept free of foreign
debris including, but not limited to tires, bottles, light bulbs, gloves, syringes or any other solid
waste. As noted in your letter, insulation was present in the lagoon due to recent roof repairs of
barns. This clean up is a continuing process, as it works to the side of the lagoon.
Please let me know if there are any concerns about this submission and kindly confirm receipt of
our responses and that requirements have now been met. I may be reached at 252-230-9443.
Sincerely,
David L. Kumm, Farm Manager

Compliance Timeframes:
If the sludge level is equal to or higher than the stop pump level of the lagoon or if the sludge level
results in an elevated waste analysis, a sludge management plan that meets the requirements of SB
Interagency Group Guidance Document 1.26 must be prepared by a technical specialist and submitted tc
DWR within 90 days. Work to reduce the sludge level must begin within another 180 days. Compliance
with NRCS Standard 359 must be achieved within two years of the original sludge survey.
If the sludge level is non -compliant but below the stop pump level of the lagoon, a POA must be filed
within 90 days and compliance with NRCS Standard 359 must be achieved within two years of the
original sludge survey indicating non-compliance. If future sludge surveys do not show improvement in
sludge levels, DWR may require the owner to develop a sludge management plan that meets the
requirements of SB Interagency Group Guidance Document 1.27.

dyer Jiickness is 2.5 feet and the existing liquid treatment zone is 3.5 feet. If the lagoon has a designed sludge storage volume,
see notes at end of the worksheet. The dimensions of the lagoon as measured and the side slope are needed
for calculations of sludge volume and of total treatment volume. If the lagoon is a standard geometric shape, the sludge
volume and the treatment volume in the lagoon can be estimated by using standard equations. For approximate volumes
of rectangular lagoons with constant side slope, calculate length and width at the midpoint of the layer, and multiply by layer
thickness to calculate layer volume, as shown in the example. For irregular shapes, convert the total surface area to a square

Appendix 3. Worksheet for sludge volume and treatment volume
Revised August 2008
The average thickness of the sludge layer and the thickness of the existing liquid (sludge -free) treatment zone are determined
from the information on the Lagoon Sludge Survey Form ( Items 0 and P, respectively). In this example, the average sludge
layer thickness is 2.5 feet and the existing liquid treatment zone is 3.5 feet. If the lagoon has a designed sludge storage volume,
see notes at end of the worksheet. The dimensions of the lagoon as measured and the side slope are needed
for calculations of sludge volume and of total treatment volume. If the lagoon is a standard geometric shape, the sludge
volume and the treatment volume in the lagoon can be estimated by using standard equations. For approximate volumes
of rectangular lagoons with constant side slope, calculate length and width at the midpoint of the layer, and multiply by layer
thickness to calculate layer volume, as shown in the example. For irregular shapes, convert the total surface area to a square
or rectangular shape. For exact volumes for lagoons with constant side slope, the "Prismoidal Equations" may be used.
Example Your Lagoon
1. Average sludge Layer Thickness (T) 2.5 ft. 3.9 ft.
2. Depth of the lagoon from top of bank to bottom soil surface (D) 11 ft. 11.5 ft.
3. Slope = Horizontal/ vertical side slope (S) 3 2.0
4. Length at the top of inside bank (L) 457 ft. 798.0 ft.
5. Width at top inside slope (W) 229 ft. 314.0 ft.
6. Length at midpoint of sludge layer Lm = L-2S(D-(T/2)) 398.5 ft. 759.9 ft.
7. Width at midpoint of sludge layer Wm= W 2S(D-(T/2)) 170.5 ft. 278.0 ft.
8. Volume of sludge (Vs) Vs=Lm Wm T 169,860 ft3 825,996 ft3
9. Volume in gallons: Vsg=V*7.5 gal./ft3. 1,273,950 gal. 6,194,971 gal.
10. Thickness of existing liquid tmt. zone (Y) 3.5 ft 3.7 ft
11. Thickness of total treatment zone (Z) Z= T+Y 6 ft 7.6 ft
12. Length at midpoint of total tmt. zone LZ = L-2(S)(D-(Z12) 409 ft. 767.3 ft.
13. Width at midpoint of total tmt. Zone WZ = W-2(S)(D-(Z/2) 181 ft. 283.3 ft.
14. Volume of total treatment zone (Vz) Vz = LZWZZ 444,174 ft3 1,649,566 ft3
15. Ratio (R) of sludge layer volume to total Treatment Volume
R = Vs/Vz
0.38 0.50
If the ratio R exceeds 0.50, than a sludge Plan of Action may be required. Check with DWQ for information
on filing the Plan of Action.
Note: If the lagoon has a designed sludge storage volume (DSSV), subtract that volume from both the volume
of sludge (Vs) (Item 8) and from the volume of total treatment zone (Vz) (Item 14), and take the ratio.
Then, R = (Vs-DSSV) / (Vz - DSSV)
Example: If DSSV = 85,000 ft3, then R = (169,860 - 85,000) / (447,174 - 85,000) = 84,860 / 362,174 = 0.24.

Appendix 3. Worksheet for sludge volume and treatment volume
Revised August 2008
The average thickness of the sludge layer and the thickness of the existing liquid (sludge -free) treatment zone are determined
from the information on the Lagoon Sludge Survey Form ( Items 0 and P, respectively). In this example, the average sludge
layer thickness is 2.5 feet and the existing liquid treatment zone is 3.5 feet. If the lagoon has a designed sludge storage volume,
see notes at end of the worksheet. The dimensions of the lagoon as measured and the side slope are needed
for calculations of sludge volume and of total treatment volume. If the lagoon is a standard geometric shape, the sludge
volume and the treatment volume in the lagoon can be estimated by using standard equations. For approximate volumes
of rectangular lagoons with constant side slope, calculate length and width at the midpoint of the layer, and multiply by layer
thickness to calculate layer volume, as shown in the example. For irregular shapes, convert the total surface area to a square
or rectangular shape. For exact volumes for lagoons with constant side slope, the "Prismoidal Equations" may be used.

Note: If the lagoon has a designed sludge storage volume (DSSV), subtract that volume from both the volume
of sludge (Vs) (Item 8) and from the volume of total treatment zone (Vz) (Item 14), and take the ratio.
Then, R = (Vs-DSSV) / (Vz - DSSV)
Example: If DSSV = 85,000 ft3, then R = (169,860 - 85,000) / (447,174 - 85,000) = 84,860 / 362,174 = 0.24.

If Item 0 is equal to or less than Item P, you do not have to determine volumes.
