Thank you again (I'll stop thanking you every time

With respect to the home depot site, you are right, they (home depot) will be responsible for the maintenance of all of these features (stormceptors, pond, wetland, etc.). I forwarded excerpts of your e-mail to John. Please note that Planning had a lot to do with this application, including Roger Wells, etc.

Prof. Dr. Bill Mitsch may be worth a call, Renee because he has been
highly recommended by Prof. Dr. Pick of Ottawa Univ., and I know the
reputation of Prof. Pick.

Mitsch's email and phone #s are below. I will appreciate knowing what
transpires since I will not be calling him.

Incidentally, I met with Andrew of Strescon for several hours today and it
appears the Stormceptor is a good device for the flows it is designed for.
He gave me literature which I will be reading in the coming days. It
appears to be a simple device, not as complicated as others, hence are
cheaper and/or easier to maintain on decadal time scales.

It appears the Stormceptor could be beneficially used as a `detention
device' instead of a detention pond, and then the outflow should be
DISPERSED over a constructed wetland. Wet ponds may in themselves export
fine sediments the way it happened at a subdivision at Second Lake several
years back, and Ted Tam PEng of HRM Design Engineering can tell you the
problems of digging ponds in clayey soils, and the export of fine sediment
not only during construction but also post-construction due to erosion of
the side slopes, etc.

After preliminary settling in the Stormceptor, then the dissolved and the
real fine particles could be removed in a properly constructed wetland
which would act as a `polishing device' if properly designed and planted
with the proper vegetation, and the McCarrons urban engineered wetland in
Minnesota as I understand works in cold climates as well!! Prof. Dr.
Gordon Ogden III of Dalhousie Univ., now deceased, used to recommend such
aspects on our channel-10 Tv shows way back in 1988 as well!

Andrew also gave me a copy of the design plan for the Home Depot in
Dartmouth, and they appear to have done an excellent job.

VIMP: All of you, i.e., HRM staff, the consutlants and the Home Depot
should be CONGRATULATED on trying your best to `minimize' the future flow
of pollutants into Russell Lake which my group has `studied to death' more
or less, not just the chemistry but also the biology of the said lake. I
also like the idea where they used 2 stormceptors which Andrew pointed out
to me.

=== Only thing left now is for HRM to carry out regular maintenance as
recommended in the Stormceptor manuals, though I think the Home Depot one,
being on private property, they would look after it!

VERY IMPORTANT: Please also convey MY PERSONAL CONGRATS to John Sheppard
PEng and I will appreciate it.

Important PS: If John could/may recall, I had recommended exactly that
kind of design way back in the late 1980s when I was the Chairman of the
Sackville Rivers Advisory Board (a Committee of the County Council then),
and I still have some of the correspondence I addressed to Warden Laszlo
Lichter I recall as well as gave several weekly press releases to
reporter, Rosemary Godin, first of the Daily News, and later on of the
Chronicle Herald. I renewed those calls in the early to mid- 1990s as well
to both the County as well as to the City of Dartmouth. To the City of
Dartmouth in the case of Portland Estates West. I made a presentation to
the full Dartmouth City Council then! Ofcourse there were no
`stormceptors' then, but the concept I proposed was similar, and I had
gotten the idea from a USEPA NPS manual (so I am not taking any credit, I
had acted just as a messenger)!
