Sodus Bay Working Group of the Natural Resources Committee, Wayne
County Master Plan, April 7, 2003
The working group met from 7 to 8:30 pm at the Newark Cooperative
Extension. The Natural Resources Committee meeting previously scheduled
for this time was cancelled because of the ice storm and its effects,
but Cynthia Hill, Master Plan consultant, and Glen Stell decided
to use the time to discuss stewardship of Sodus Bay, since both
appeared for the cancelled Natural Resources meeting. Stell represents
both himself and Save Our Sodus, a citizen group committed to improving
the quality of life around and in Sodus Bay.
Hill suggested that SOS might be interested in soliciting contributions
for a revolving fund, which the Genesee Finger Lakes Land Trust
could use to buy land, subdivide it in an environmentally sound
manner (including placement of conservation and other easements),
and then resell in part or in total to a developer. Once the initial
property is resold, the money would become available to subdivide
another parcel in accordance with the public interest (rather than
in accordance with commercial interests that may or may not be in
concert with the public interest).
Glen reiterated that SOS favors increased public access to Lake
Ontario and its embayments. In addition, SOS believes the protection
of water quality should play a key role in the County Master Plan.
To protect water quality, we must keep impurities from entering
stormwater as it travels both over and under ground from the crest
of the Sodus Bay watershed to the Bay itself.
Hill suggested four steps that communities can take to enhance
water quality. Hill suggested treating the leachate from septic
tanks to further purify the liquid before allowing it to flow into
Sodus Bay (secondary treatment). In Norway, environmental regulations
are much more strict than in the USA and everyone must remove almost
all the nitrogen and phosphorus from their septic leachate using
technology such as on-site constructed wetlands. Septic tanks remove
pathogens and carbon, but do nothing to treat nitrogen and phosphorus.
These elements flow from the leachate fields toward Sodus Bay. Phosphorus,
if the soil and hydraulic pathways are optimal, may adhere to soil
particles. Moreover, if there is enough land between the leachate
field and the Bay, there is a chance that, within alternating oxic
(aerated) and anoxic (void of oxygen) environments, special soil
microbes might convert nitrogen to gaseous form (nitrogen gas).
In these ideal cases nutrients would not enter the bay. The placement
of homes close to the Bay, however, rarely allows for these optimal
scenarios. A portion of the nitrogen typically travels underground
to Sodus Bay. Phosphorus often flows through pores in the soil called
preferential flow paths. Once in the Bay, these nutrients become
food for plants and animals, commonly called weeds and algae.
Hill suggested that to provide the best chance for natural treatment
of phosphorus and nitrogen, new homes should not be allowed to place
leachate fields close to the bay. The exact distance would depend
on the soil type, slope, and hydrology of the land.
Another way to reduce the flow of nutrients into the Bay is to
encourage farmers to apply phosphorus very conservatively when fertilizing
their fields. Often phosphorus is applied in excess of agronomic
requirements because fertilizer is spread with the goal of adding
the correct amount of nitrogen to promote optimal yields. The ratio
of phosphorus and nitrogen in fertilizer or manure is often fixed.
Another suggestion is for communities to volunteer to use ECOVER
or similar products (7th Generation brand?) for household and personal
hygiene. Although this might sound like a novel idea, it isn't!
These ECOVER products were developed in Belgium and then tested
in Sweden by an independent ecological engineer, who found that
when whole communities made the voluntary commitment to use the
most ecologically sustainable cleaning products, the resulting sewage
could easily be turned back into potable water. The researcher,
committed to protecting a watershed of the Baltic Sea, treats the
sewage in a greenhouse using plants and animals to soak up the nutrients
and other impurities, such as heavy metals.
One of the most important ways to promote water quality in Sodus
Bay is to adopt strict controls for stormwater management both during
and after construction. Stormwater management prevents erosion by
slowing water down as it travels to the Bay. It also allows for
the settling of solids (including sorbed phosphorus) and the removal
of nitrogen retention or detention basins or in natural or constructed
wetlands.
These are four ideas that interested citizen groups might suggest
endorsing for inclusion in the County Master Plan.
