I read the entire article and I have a problem with one bit of it:
"Can sewage be treated onboard instead? Yes, some manufacturers offer Type II treatment systems that clean waste sufficiently to allow its return to host waters. But these are usually large and expensive units and performance can vary. Consider manufacturers’ claims carefully. The new regulations do not certify any such equipment but they do set minimum standards of cleanliness that such systems must meet. This standard – a maximum fecal coliform count per unit of water of 250 per 100 ml – is a challenging one. Remember, though, that regardless of treatment, no discharge is allowed within one mile from shore anywhere. So a holding tank is required in any case."
Apparently that's based only on the maximum bacteria count from a Type I MSD (treatment device) allowed by US marine sanitation laws (1000/100 ml), when the actual bacteria count from all 3 Type I devices made in the US (Raritan ElectroScan and PuraSan and Groco ThermoPure) is <10/100 ml...which is a fraction of the max allowed by Type II (200/100 ml and only required on boats over 66' LOA that install treatment)...so not "challenging" when it comes to meeting the Canadian standard at all...in fact is cleaner than the discharge from any sewage treatment plant, which where all holding tank contents that aren't illegally dumped end up.
I've bookmarked that article--which, btw, is a lot more current than what's in my files and I thank you for posting it!--and may pursue this.
