MOE on SLUDGE

From the PEC Council meeting, at which Bruce Hancock, District Manager for the Ministry of the Environment, presented his report about the spreading of sludge.

Some highlights:

  • the spreading of sludge is not waste management, it is a beneficial activity
  • the quality of sludge is monitored in accordance with the guidelines (?)
  • spreading is prohibited on snow-covered or frozen ground
  • Certificates of Approval are given for a 5 year period; the sludge can either be spread all at once, or spaced over the five years
  • Soil samples are submitted before approval, but MOE does not test the samples; they are tested at independent laboratories, and the MOE takes their word for it
  • at the end of 5 years, another Certificate of Approval can be granted, and no soil sample is required
  • Certificates of Approval are not circulated and are not subject to review
  • the MOE does some inspections on a yearly basis; last year, 15 of 400 sites in Eastern Ontario were inspected
  • inspections are also conducted if there has been a complaint
  • in the case of the heavy metal content being above recommended levels (as in the case of Belleville), the sludge is mixed with other sludge within the acceptable levels, or it is applied at a reduced rate (Belleville). Belleville's sludge is now "almost at compliance level".
  • there is no direction that sludge cannot be spread on tile-drained fields, even though the reason given for revoking a certificate in Picton was that it was on a tile-drained field
  • the MOE does not impose the obligation for a Municipality to notify the residents
  • it is the property owner who bears the liability if there is an adverse effect
  • the Municipality does not have the right to prohibit the importing of sludge from another area
  • it is the field owner's decision as to from whom he takes sludge; if he decides to take sludge from a source outside of the county, and the county has no sites available for its excess sewage sludge, then that's too bad
  • the MOE does not do any sampling
  • the MOE does not look at the impact of the spreading on a number of fields in the same area
  • there is no evidence of groundwater being affected
  • there is no testing to determine if harmful bacteria are surviving the treatment process; only Toronto has taken it upon itself to do so.
