He said it was a successful meeting that identified areas where the local enforcement personnel had issues or difficulties.
As enforcers these were the people who were charged with dealing with events ranging from chemical spills (in which case they would need to know what other agencies to contact) to ensuring compliance with rules such as not flushing certain substances into stormwater systems.
Issues that they identified were the need for more co-ordination, sharing information, maintaining skills, training and funding expertise within staff.
"Environmental issues are quite complicated and require a multi-agency approach," Mr McMillan said.
"That's what's driving us to engage with those responsible and see where we can improve the system, whether that's practically or a long-term strategy we need to start working on now."
Mr McMillan said the workshops would be held with all 66 territorial authorities by June this year.
