Recommendations |
| Liquid PCP/oil solutions |
- Spilled PCP/oil concentrates
- PCP work solutions
- Drips from freshly treated lumber
- Material skimmed from oil separators
|
|
| Liquid PCP/water solutions |
- Condensates
- Washwaters
- Infiltrating waters
|
- Treat to remove oil and PCP to within regulatory limits.
- Dispose of treated waters as per regulatory requirements.
|
| Contaminated solid wastes |
- Debris and bottom sludge from storage tanks, sumps and pressure cylinders
- Soils contaminated by spills
- Cleanup absorbents
- Filter from cleaning vacuum
- Sludges from wastewater treatment processes
- Solid fire residues from PCP or PCP/oil storage areas
- Wrapping used for PCP blocks
- Scraps, cuttings and shavings from PCP-treated lumber
|
- Drain and/or drum, store and dispose of in accordance with provincial regulatory requirements (high-temperature thermal destruction at authorized facilities appears to be the most feasible disposal option).
|
| Miscellaneous solid wastes |
- Empty containers and wrapping rinsed with alkaline water
|
- Dispose of in authorized sanitary landfills (subject to approval by the provincial regulatory agency).
- Recuperated by authorized facilities.
|
| Contaminated storm runoff |
- Storm runoff or contaminated liquid discharges containing PCP requires consultation with regulatory agency.
|
- Prevent or minimize contamination of storm runoff to greatest possible extent.
- Monitor surface water discharges (in consultation with the provincial regulatory agency) to assess contaminant concentrations and determine the need for control.
- Provide mean for collection of contaminated storm runoff.
|
| Firefighting water runoff |
- As above (contaminated storm runoff)
|
- Consider provisions for containment where PCP and PCP/oil solutions are present.
- Consult with provincial regulatory agency to determine acceptable disposal practices.
