EHS&RM – Hazardous Waste Management Manual, App J, Accumulation of Non-regulated waste

PROCEDURES FOR DISPOSAL OF NON-REGULATED WASTE

The following checklist should be used in determining whether or not a waste may be disposed of in the sanitary sewer or municipal trash. This checklist does not apply to wastes which are radioactive or mixed in nature.

Does the material meet any of the following criteria?  (see Hazardous waste manual)

_____ Is it ignitable?

_____ Is it corrosive?

_____ Is it toxic?

_____ Is it an F listed waste?

If the material has not been used, does it meet any of the following criteria?   (see Hazardous waste manual)

_____ Is it a P listed waste?

_____ Is it a U listed waste?

If the answer to any of the preceding questions is “yes,” then the waste is regulated and must not be disposed of via sanitary sewer. Please refer to the disposal procedures outlined in Hazardous waste manual.

If the material is not a hazardous waste, please answer the following questions:

_____ Is the material miscible in all proportions with water?
If the answer to the preceding question is “no,” then the waste is prohibited by the City of Las Cruces POTW and must not be disposed of via sanitary sewer. Please refer to the disposal procedures outlined in manual.
_____ Does the sum of the concentrations of the following constituents in the waste exceed 2 ppm?


_____ Does the waste contain any of the following constituents at levels greater than the specified amount?

 

  • Copper
 1.9 mg/L
  • Nickel
 1.6 mg/L
  • Zinc
 2.3 mg/L
  • Fluorides
 65 mg/L
  • Cyanides
 1.0 mg/L
  • Manganese
 6.1 mg/L

POTW Limits on Wastewater Strength


_____ Is it extremely toxic or a known carcinogen or mutagen?

 

If any answers to the three preceding questions are “yes,” then the waste is prohibited by the City of Las Cruces POTW and must not be disposed of via sanitary sewer.

 

Please refer to the disposal procedures outlined in this manual. Otherwise, the material is acceptable for sanitary sewer disposal if it is a liquid or for trash disposal if it is a solid. The discharge of wastes to the sanitary sewer should be accompanied with copious amounts of water – a good rule of thumb is to use a 100-fold excess of water when discharging wastes to the sanitary sewer.

The following are examples of nonhazardous chemicals which may be disposed of either in the general trash (for solids) or the sanitary sewer (for liquids).

  • Adenosine 3′-monophosphate, sodium salt
  • Albumin, bovine, methylated
