Table 23. Recommended Disposal Practices for PCP-Contaminated Wastes

(Use in conjunction with Part I, Chapter A - General Recommendations for All Wood Preservatives, Table 23.)

Waste category	Examples	Recommendations
Liquid PCP/oil solutions	Spilled PCP/oil concentrates PCP work solutions Drips from freshly treated lumber Material skimmed from oil separators	Collect and reuse.
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.
