first_img The health and safety of Nova Scotians are the focus of proposednew rules for applying biosolids to land. The Department ofEnvironment and Labour is now seeking public comment on the newrules. “We need a safe, stable, long-term solution to the disposal ofmaterials left over from sewage treatment,” said Kerry Morash,Minister of Environment and Labour. “These guidelines will giveus that.” The draft guidelines will allow only treated sludges that meetspecific biological and chemical criteria to be applied to theland. No untreated septage or sewage sludges can be used. Septage sludge is the solid material that remains after water isremoved from the sediments pumped from a septic tank. Sewagesludge is the residue generated during the treatment of sewage ina treatment plant. Once they are treated to meet biological andchemical standards, they are called biosolids. “Land application of biosolids is the best alternative fordisposal of these materials,” Mr. Morash said. “Sending it to alandfill is expensive and not consistent with our wastemanagement strategy. Incineration is the only other option andthat’s expensive and not environmentally responsible.” The draft guidelines result from a department review of approvalpractices that began in the fall of 2003. In January, governmentdirected the department to suspend current land-applicationapprovals and to stop issuing new approvals for land applicationof sewage and septic sludges. The guidelines, when finalized and approved by government, willbecome part of any approval issued by the department for landapplications. The public comment period ends on Friday, April 16. The draftguidelines are available on the department’s website ; at any Environment and Labour office; or bycalling 1-800-567-7544.
