D. RATIONALE FOR LIMITATIONS:
As listed on the IUP Limits Page(s), PART I, Section F of the IUP.
RATIONALE#1:
Review of IU Monitoring Data,with no Over Allocation situation:
The following pollutants were assigned numerical limits in this IUP based on
a review of monitoring data for the permittee to determine what ranges of
concentrations are currently being discharged. To account for sample
variability a factor was applied to the monitoring data to determine the permit
limit. Permit limits assigned by the Local IUP Control Authority can not
result in an Over Allocation situation for any pollutants.

RATIONALE#2a:
Categorical Industrial Limits, with no Over Allocation situation:
Check here if Combined Wastestream Formula (CWF) or other categorical
limits calculations were used. If used, Please attach calculations: (see CWF
Spreadsheet, Appendix 6-F)
Were used (attach calculations)
Were not used X
The following pollutants were assigned numerical limits in this IUP based on
the categorical regulations. These limits do not result in over allocations.
RATIONALE#3 a:
Over Allocation Prevention, with IU pollutant reduction:
The following pollutants were assigned numerical limits in this IUP based on
allocating the Maximum Allowable Industrial Loading (MAIL) determined
with the Headworks Analysis (HWA) among all Industrial Users. The total
loading of each pollutant from all permitted discharges does not exceed the
MAIL. These limits do not result on over allocations.
BOD, TSS, Ammonia
RATIONALE#3b:
Interim Limits for IU pollutant reduction:
The following pollutants were assigned interim numerical limits in this IUP
to allow time for the industry to come compliance with final limits that will
not result in over allocations.

4.) Other Rationale for Limitations:
The following rationale was used for developing IUP Limits.
Parameter Rationale
Chloride Stream Standard
Total Phosphorus Stream Standard
RATIONALE#5a:
Non-Categorical Parameters where No Limit needed or assigned in an IUP:
The following pollutants were not assigned numerical limits in this IUP
because the loadings for these pollutants from this IU were less than 5% of
the MAHL. The loading of these pollutants from this IU is considered
insignificant at this time.

Part V, Waste Reduction Information :
State Pretreatment Rule 15A NCAC 2H.0916 (c)(1)(M) requires Significant Industrial
Users to include a description of current and projected waste reduction (pollution
prevention) activities. The codes listed are standard EPA codes found on Toxic Release
Inventory and other environmental forms. Please check all applicable codes for your
facility related to wastewater discharge.
Current Projected Code Description
W 13 Improved maintenance scheduling recordkeeping, or procedures
W 14 Changed production schedule to minimize equipment and feedstock
changeovers
W 19 Other changes in operating practices (explain briefly in comments)
W21 Instituted procedures to ensure that materials do not stay in inventory
beyond shelf-life
W22 Began to test outdated material-continue to use if still effective
W23 Eliminated shelf-life requirements for stable materials
W24 Instituted better labeling procedures
W25 Instituted clearinghouse to exchange materials that would otherwise
be discarded
W29 Other changes in Inventory control (explain briefly in comments)
W31 Improved storage or stacking procedures
W32 Improved procedures for loading, unloading and transfer operations
W33 Installed overflow alarms or automatic shutoff valves
W34 Installed secondary containment
X W35 Installed vapor recovery systems
W36 Implemented inspection or monitoring program of potential spill or
leak sources
W39 Other spill and leak prevention (explain briefly in comments)
W41 Increased purity of raw materials
W42 Substituted raw materials
W49 Other raw material modifications (explain briefly in comments)
X W51 Instituted recirculation within a process

Current Projected Code Description
W52 Modified equipment, layout, or piping
W53 Use of a different process catalyst
W54 Instituted better controls on operating bulk containers to minimize
discarding of empty containers
W55 Changed from small volume containers to bulk containers to
minimize discarding of empty containers
W58 Other process modifications (explain briefly in comments)
W59 Modified stripping/cleaning equipment
W60 Changed to mechanical stripping/ cleaning devices (from solvents or
other materials)
W61 Changed to aqueous cleaners ( from solvents or other materials)
W62 Reduced the number of solvents used to make waste more amenable
to recycling
W63 Modified containment procedures for cleaning units
W64 Improved draining procedures
W65 Redesigned parts racks to reduce dragout
W66 Modified or installed rinse systems
W67 Improved rinse equipment design
W68 Improved rinse equipment operation
W71 Other cleaning and degreasing operation (explain briefly in comments)
W72 Modified spray systems or equipment
W73 Substituted coating materials used
W74 Improved application techniques
W75 Changed from spray to other system
W78 Other surface preparation and finishing (explain briefly in comments)
W81 Changed product specifications
W82 Modified design or composition of product
W83 Modified packaging
W89 Other product modifications (explain briefly in comments)
W99 Other (specify in comments )
Comments (Please list corresponding code)
The facility serves to extract beneficial use from poultry manure. Water recycling within the
process is robust. Methane emissions are essentially eliminated by combustion in the CHPs.
