Strategic vs. Tactical Records

• Strategic Records - Completed once for NPDES
  permit 5-year cycle.
• Includes permit
• May need occasional review/update
• May need to be translated into employee SOPs and
  employee training
• Tactical Records
• Require regular updates additions

Overview (Section A)
v

• Plan documentation (NPDES permit application)
  addressing nine elements of a NMP
• Adequate storage
• Mortality
• Clean water mgmt.
• Animal contact with waters of US
• Chemical handling
• Conservation practices
• Testing or manures and soil
• Land application methods
• Records

5
Animal Management (Section B)

• Manure Production

• Inventory or animal populations, mortalities,
  other_________________

• Daily inspections of water lines (records
  large CAFO only)

6
Manure Handling Storage (Section C)

• Facility documentation (permit)

• Inspections (all CAFOs) log of inspections
  (large CAFOs)
• Diversion and collection structures
• Storage liquid level (all CAFOs)
• Sludge sediment accumulation
• Storage structure (?)
• Pumping equipment (?)
• Deficiencies corrections (all CAFOs)

• Pumping log Pumping start stop times, rates,
  liquid levels, precipitation

7
Land Treatment Practices (Section D)

• Map of application sites with setbacks,
  restrictions, conservation practices identified
  (permit)

• Results of P Index assessments (found in Title
  130 not addressed in federal rules) for Large
  CAFOs only

8
Crop Nutrient Management (Section E)

• Standard operating procedures for soil and manure
  testing.

9
Standard Operating Procedure
10
Crop Nutrient Management (Section E)

• Standard operating procedures for soil and manure
  testing.

• Field Nutrient Balance (fertilizer manure)
• Procedures for estimating application rates
• Pre-season plan for N P application
• Post-season summary of crops grown, yields, and N
  P applied

• Equipment operator plan identifying location,
  rate, form, and method of all nutrients to be
  applied (?)

11
Crop Nutrient Management (Section E)

• Field specific application record
• dates and amounts actually applied
• Weather conditions 24 hr before to 24 hr after
  (Large CAFOs)

• Manure and soil test results

• Inspection of application eqpt. (including
  irrigation systems
• Dates (all CAFOs)
• Log of inspections (large CAFOs)
• Maintenance records (all CAFOs)
• Calibration results (?)

RecordsCycle Crop NMP
Strategic Records - Permits documentation -
SOP for soil/manure sampling - P Index (every
five years)
Pre-Season - Nutrient based application plan
- Plan for eqpt. operator -
Manure soil samples - Equipment

Post-Season - Actual yields - Actual manure
nutrients applied
Feed Manure
In-Season - Equipment calibration - Record
of application rates - Report of discharges
13
Record Keeping (Section F)

• Manure spills reports

• Annual NPDES report

14
Other Utilization Activities (Section G)

• Alternative Technology documentation (permit)

• Manure transfers (3rd party ID, date, amount).

• Alternative technology inspection, maintenance,
  and performance ???
• check NPDES permit

15
Performance (Section G)

• Measures of performance
• P Index results
• Field summaries of nutrient balance
• Actual yields
• Storage levels
• Past manure spills

• Optional measures of performance
• Stalk nitrate tests
• 3rd party review of risks
• Whole farm nutrient balance

16
Questions

• Modifications to Checklists?
• What should be done to promote better records?

17
Separating Strategic vs Annual Crop Nutrient
Plans in NPDES Process(Heartland WQ Project
Effort )

• Avoid identifying application rates and final
  application sites in permit
• Minimize need to modify permit
• Provide producer with instructions for adapting
  rates and application sites
• Recognize the value (importance) of soil and
  manure testing

18
Strategic Crop Nutrient Plansfor NPDES Permit
(Heartland WQ Project Proposal )

• Crop Nutrient Requirements
• Calculations
• Assumptions
• Producer Instructions
• Manure Fertilizer Application Rates
• Calculations
• Assumptions
• N-Based rate considerations
• P-Based rates consideration
• P Index application
• Producer instructions

19
Strategic Crop Nutrient Plansfor NPDES Permit

• Sample Annual Plan ( for crop year immediately
  after NPDES permit submission - one year only)
• Manure analysis results
• N-Rate calculation results
• P-rate calculation results
• Most recent P-Index results
• Field summary nutrient application plan (rate,
  method, timing, location)
