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
X W13 Improved maintenance scheduling recordkeeping, or procedures
W14 Changed production schedule to minimize equipment and feedstock
changeovers
W19 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W22 Began to test outdated material-continue to use if still effective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
X 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)
X W31 Improved storage or stacking procedures
X W32 Improved procedures for loading, unloading and transfer operations
X W33 Installed overflow alarms or automatic shutoff valves
X W34 Installed secondary containment
W35 Installed vapor recovery systems
X W36 Implemented inspection or monitoring program of potential spill or
leak sources
W39 Other spill and leak prevention(explain briefly in comments)
W4 1 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
X W52 Modified equipment, layout,or piping
W53 Use of a different process catalyst
X W54 Instituted better controls on operating bulk containers to minimize
discarding of empty containers
X 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
X 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)

NOTE:
1) Mass allowance values are obtained from Table 3,rounding to the nearest 0.001,except for
fluoride and ammonia,which are rounded to the nearest 0.1.
2) Allowable Permit Limits(Total Flow):
a) (lb/day)values are those calculated in Table 2.
b) (mg/L)=(lb/day)x Total Flow(gal/day)x 8.344 lb/gal/1,000,000 mg/L
