(sound of giant fans)


About a thousand cows are in this building, eating, lolling around, and waiting for the next round of milking.


There’s a sharp smell of manure hanging in the air. Big fans are blowing to keep the cows cool, and to keep the air circulated.


Stephan Vander Hoff runs this dairy along with his siblings. He says these big farms are good for consumers:


“We’ve got something here and we’ve been able to do it in such a way that we’re still producing at the same cost that we were fifteen years ago. It costs more now for a gallon of gas than a gallon of milk. And so, that’s something to be proud of.”


Vander Hoff’s dairy produces enough milk to fill seven tanker trucks everyday. They also produce a lot of waste. The cows in this building are penned in by metal gates. They can’t go outside. So the manure and urine that would normally pile up is washed away by water.


Tens of thousands of gallons of wastewater are sent to big lagoons outside. Eventually, the liquefied manure is spread onto nearby farm fields. It’s a challenge for these farmers to deal with these large pools of liquid manure. The farther they have to haul it, the more expensive it is for them. Almost all of them put the manure onto farm fields.


It’s good for the crops if it’s done right, but if too much manure is put on the land, it can wash into streams and creeks. In fact, this dairy has been cited by the state of Michigan for letting their manure get into nearby waterways.

She weaves her way down to the edge of this creek.


“This is the area where we got E. coli at 7.5 million.”


High E. coli levels mean the water might be polluted with dangerous pathogens. Lynn Henning is testing the creek today because she saw farmers spreading liquid manure on the fields yesterday. Henning is a farmer turned environmental activist. She works for the Sierra Club and drives all over the state taking water samples and pictures near big livestock farms.


Henning says she got involved because more of these large animal farms expanded into her community. She says when the farmers spread the liquid manure, it can make life in the country pretty difficult:


“The odor is horrendous when they’re applying –we have fly infestations–we have hydrogen sulfide in the air that nobody knows is there because you can’t always smell it. We have to live in fear that every glass of water that we drink is going to be contaminated at some point.”


Water contamination from manure is a big concern. The liquid manure can contain nasty pathogens and bacteria.


Joan Rose is a microbiologist at Michigan State University.


“If animal wastes are not treated properly and we have large concentrations of animal waste going onto land and then via rainfall or other runoff events entering into our water – there can be outbreaks associated with this practice.”


Rose tested water in this area and found high levels of cryptosporidium that likely came from cattle. Cryptosporidium is the same bug that killed people in Milwaukee back in 1993. Rose says livestock farmers need to think more about keeping these pathogens out of the water. But she says they don’t get much support from the state and researchers on how best to do that.


For now, the farmers have to come up with their own solutions.


(sound of treatment plant)


Three years ago, the state of Michigan sued Stephen Vander Hoff’s dairy for multiple waste violations. The Vander Hoff’s settled the case with the state and agreed to build a one million dollar treatment system. But Vander Hoff isn’t convinced that his dairy was at fault, and thinks that people’s concerns over his dairy are overblown:


“If we had an issue or had done something wrong the first people that want to correct it is us. We live in this area. So why would we do anything to harm it?”


Vander Hoff is upbeat about the new treatment system. He says it will save the dairy money in the long run.


The Sierra Club’s Lynn Henning says she’s skeptical of the new treatment plant. She’ll continue to take water samples and put pressure on these farms to handle their manure better. In the end, she doesn’t think these big farms have a place in agriculture. She’d rather see farms go back to the old style of dairying, where the cows are allowed to graze, and the number of animals isn’t so concentrated.


But farm researchers say because consumers demand cheap prices, these large farms are here to stay and there will be more of them. Because of this, the experts say we can expect more conflicts in rural America.

Farmers Respond to Peer Pressure

  • Farming is big business in America's heartland. Many farmers say they want to be left alone to run their farms the way they always have - and they don't want government regulators or researchers dictating to them. (Photo by Rebecca Williams)

Farm pollution is the biggest water contamination problem in the
nation. But government agencies often struggle with getting farmers to
use less polluting farming methods. Many farmers say they don’t want
outsiders telling them what to do. Rebecca Williams reports one
grassroots project is trying to encourage farmers to change, by relying
on peer pressure:


(Sound of birds and buzzing insects)


The corn around here is way over knee high, and there’s a whole lot of
it. This is Iowa, after all. So, pretty much everyone farms corn and
soybeans.


But there isn’t as much farming happening today. Dozens of farmers are
hanging out by a creek that meanders through farmland. They’re
checking out the day’s catch.


(Sound of splashing around in bucket)


“Now there’s one really bright-colored southern red belly in here, kind
of the prettiest fish we’ve got in this stretch.”


Biologist Dan Kirby just used an electroshocker. It stuns the fish and
they float to the top of the water. Now that he can see them, he can
get an idea of how many fish there are and how big they are. The
farmers are watching closely.


(Farmer:) “That’s a real good sign to see them that big, at this
point?”


(Kirby:) “Yeah, especially the southern red belly – they do classify
them a little bit different, they consider them to be a sensitive
species, so it’s a good thing to have them there at that adult size,
for sure.”


That’s better news than they might’ve been expecting. This creek
running along many of the farmers’ fields is in trouble. It’s on
Iowa’s impaired waters list. In this case, that means the fish and
other aquatic life in the creek are not doing as well as they should
be.


“In some of these streams we have had some rough times. Chronic issues
where fish were not even getting to size they could catch them or else
were just plain absent.”


Dan Kirby says farm pollution such as excess fertilizer and soil
erosion from farm fields can harm fish and other stream life. That’s
the kind of thing that put this creek on the government’s watch list
three years ago.


One of the farmers, Jeff Pape, remembers hearing about that. For him it was a big
red flag:


“We knew there was an impaired waterway and it was running through some
of the land I rent and obviously I don’t want that to shine on me… I
didn’t want the DNR – not that they would or have the time to do
it, but I didn’t want them to come in and say hey, you will be doing
this, or you will be doing that.”


Pape says the fear of being dictated to by the government was a strong
motivator for him and a few of his neighbors. In late 2004, Pape
formed a watershed council with nine of his farming neighbors.


Now there are nearly 50 farmers in the group. Pape says there are some ground
rules: No finger pointing. And everyone gets equal say:


“That’s nice with this group – nobody’s telling them they have to do
anything – they do what they want when they want and that’s it. You
know, they don’t do any more than they want to.”


Pape says he’s proud of what he and his neighbors have gotten done.
They’re installing grass strips along ditches and creeks to filter
water rushing off fields. They’re putting in fences to keep cattle
from tearing up stream beds and banks. They’re being more careful
about how much fertilizer they apply.


Maybe most importantly, they’ve gotten a lot of their neighbors to join
them. Jeff Pape says cash incentives help – farmers are paid for the
conservation projects they do. It’s not as much money as some of the
government’s conservation programs, but it keeps the government out of
their hair.


Pape says this program works because there’s an even stronger
motivation:


“That guy’s looking over your fence – he sees you ain’t got a waterway
and you’re thinking about it, so that peer pressure thing does make a
difference too. You know everybody’s watching each other in this
watershed – not pointing fingers at nobody but everybody’s watching
each other and that keeps people on their toes – they want things to
look right, too.”


Other farmers here agree that a farmer-to-farmer project is going to be
much more effective than anything government regulators or researchers
say.


John Rodecap is with Iowa State University Extension Service. He’s
been helping these farmers clean up the creek. He says it’s remarkable
that more than half of the farmers in this 23,000-acre watershed have
signed on.


“The trials that they do, they talk about it at their coffee shop, they
talk about it over the fence… If the trial’s done 50, 60, 100 miles
away, that’s not good enough. They want to know how it’s gonna work on
my farm.”


Rodecap says if you see your neighbor making a change first, you’re
going to feel a little more comfortable giving it a try yourself. And
knowing your neighbor’s watching you over the fence… that’s a powerful
incentive all its own.

Too Much Manure?

Today, we continue our series on pollution in the heartland.
Dairy farms are getting bigger. Many keep thousands of cows in buildings the size of several football fields. These big dairy operations can make a lot of milk. That translates into cheaper prices at the grocery store.

States to Have More Control Over Goose Populations?

The U.S. Fish and Wildlife Service plans to give the states more power in reducing the resident
Canada geese population. The Great Lakes Radio Consortium’s Karen Kelly has more:


An estimated 3.2 million Canada geese have made permanent homes on lawns, farms, and airport
runways across the U.S.


Officials say the birds collide with aircraft, damage crops and pollute water supplies.


States traditionally needed a permit to get rid of geese.


But Ron Kokel, a biologist with U.S. Fish and Wildlife, says the new proposal would allow
communities to have more say in how the bird population is managed.


“It puts the decision on exactly what management technique the state or local authorities want to
use; it puts that decision more on the local level.”


The public has until October 20th to comment to the U.S. Fish and Wildlife Service on the
proposal.

Modified Fish to Protect Water Supplies?

Some scientists working on protecting freshwater supplies from
terrorism are trying to recruit a new special agent. It’s a small fish that
may serve as a sentinel of contamination. The Great Lakes
Radio Consortium’s Chuck Quirmbach reports:


Researchers are injecting firefly genes or a fluorescent
jellyfish protein into a small tropical freshwater species
called the zebrafish. The hope is that when the genetically
modified zebrafish is exposed to environmental pollutants or
chemical warfare agents, the fish would give off light or a green signal.


University of Wisconsin-Milwaukee scientist Michael Carvan says the
fish would be placed in water coming in from a source such as Lake Michigan.


“This would kind of be like the canary in the coal mine… where if the fish
signaled that there were toxic chemicals in the water… that that would alert
the system and probably shut down water that would go beyond that point.”


Carvan acknowledges that he’s having trouble getting the zebrafish to pass along
the so-called green gene from generation to generation.

Transcript

When abandoned wells aren’t sealed properly, they can pollute the water below. And in some of
these wells, children and animals have gotten trapped. A number of states across the region are
working to solve the problem. The Great Lakes Radio Consortium’s Erika Johnson has more:


All states across the region have certain regulations for plugging abandoned wells. But not all
states have specialized programs to address the problem.


Programs to cap abandoned wells have existed in Minnesota and Wisconsin for decades. Now,
other states are developing their own programs.


Officials in Michigan face a particular challenge because more of these wells exist there than in
any other state in the country – close to 2-million by some estimates.


Jim McEwan is with the Michigan Department of Environmental Quality. He says surface
pollutants can be channeled down into unplugged wells:


“The contaminants can gain access by penetrating the corroded well casing because many of them
have been in the ground for 70 to 100 years, or so, and then going right down, like a drain, into
the lower drinking water aquifers.”


So far, Michigan, Minnesota and Wisconsin each plug about 10-to-20-thousand wells per year.


It generally takes several hours and costs a few hundred dollars to seal each well. And
homeowners have to pay for the sealing of any unused wells on their property. But some states
do offer financial assistance.

State to Ban Phosphorus in Dishwasher Soap?

Every summer, lakes become inundated with algae. As the slimy, green muck dies, it chokes out oxygen, which can kill fish and other aquatic life. One cause of all that algae – phosphorus in the water. The phosphorus comes from natural sources such as decaying leaves, and it comes in farm and lawn fertilizer, which runs off into the water. But there’s also phosphorus in a product many of us use every day – dishwasher soap – which goes directly into the water and down the drain. One state might be the first in the nation to ban phosphorus in dishwasher soap, and as the Great Lakes Radio Consortium’s Mary Stucky reports, other states might follow:

Every summer, lakes become inundated with algae. As the slimy, green muck dies, it chokes out
oxygen, which can kill fish and other aquatic life. One cause of all that algae – phosphorus in the
water. The phosphorus comes from natural sources such as decaying leaves, and it comes in farm
and lawn fertilizer, which runs off into the water. But there’s also phosphorus in a product many
of us use every day – dishwasher soap – which goes directly into the water and down the drain.
One state might be the first in the nation to ban phosphorus in dishwasher soap, and as the Great
Lakes Radio Consortium’s Mary Stucky reports, other states might follow:


(ambient sound of lapping water)


Lakes are a source of natural beauty, recreation, tourist dollars, even food. And in Minnesota
people take their lakes seriously. But when the algae takes over, no one wants to swim in the
scum, fish die for a lack of oxygen and the lake’s ecosystem is endangered.


(natural sound break)


Phosphorus occurs naturally. Some of it comes from decaying vegetation, grass clippings and
dead leaves. But because too much phosphorus is harmful, lawmakers have banned it from
certain commercial products. Last year Minnesota banned it from lawn fertilizer. And decades
ago, many states outlawed laundry detergent containing phosphorus. But they didn’t ban it in
dishwasher soap.


“There were not near the number in 1970 of automatic dishwashers in the households. It’s an
everyday thing now. ”


Ray Cox Is a Republican representative in the Minnesota legislature. He is sponsoring the bill,
banning phosphorus in dishwasher soap. There are phosphorus free dishwasher soaps, but they’re
a tiny fraction of the market. Still, Cox says phosphorus free soaps work better than they used to
because of the improvements that have been made in dishwashers.


“There are many, many products around here available right now and they work great. We’ve
used it for many years at home and there’s no problem. I mean, our dishes are clean.”


(ambient sound of dishwasher running)


Unlike other products containing phosphorus, detergent is flushed directly down the drain. For
each box of dishwasher detergent, it costs your local sewer treatment plant at least two dollars
and fifty cents to remove the phosphorus. But most cities don’t have state of the art water
treatment, so a lot of phosphorus makes its way into lakes, rivers and streams. Just how much, no
one knows exactly. One study estimates that 6 percent of the phosphorus in water comes from
dishwasher detergent, according to Don Arnosti of the Minnesota Environmental Partnership, a
coalition of 80 environmental groups.


“Removing this phosphorus will improve our waterways. How much, that’s what’s in debate. Is
it 6 percent as we suggest? Is it 8 percent? Is it 4 percent? And we say that’s not important.
Nobody is saying it’s not gonna be an improvement.”


But will the improvement be worth the cost? Tony Kwilas is a lobbyist for the Minnesota
Chamber of Commerce, which has taken the lead in attacking the ban. He says consumers won’t
stand for it because it doesn’t help that much and the replacement products are inferior.


“Why ban a product that we’re not quite sure the cost benefit of it. In Europe they went
phosphorus-free and they turned around and went back due to consumer complaints. Mainly it
sounds like there’s spotting and scratching on some of the glasses, and it doesn’t get all the food
off.”


Tony Kwilas says a ban on phosphorus in dishwasher detergent won’t really help much since
there are so many sources of phosphorus in the water.


“I’m not going to dispute that phosphorus is a problem, but if you look at what phosphorus is
contained in, it’s contained in antifreeze, it’s contained in chicken tenders, it’s contained in
bath beads, frozen fish, fire extinguishers, instant pudding, pet food, toothpaste, cake mixes. I
mean, so phosphorus is everywhere.”


To ban phosphorus in dishwasher soap would raise the cost about 70 cents a box. But most
consumers seem unaware of the issue, even those shopping at this food co-op in St Paul.


“I was not made aware that this was really harming our environment badly.” “I thought
phosphorus was already gone.” “You know, I just became aware of it, so I will start paying
attention to it right now.” “We don’t pay attention regularly.” “I had no idea that was in there
either.”


There doesn’t seem to be a consumer demand for phosphorus-free dishwasher detergent, just yet.
Don Arnosti of the Environmental Partnership says just as they did with dolphin-safe tuna and
phosphorus-free laundry soap, consumers need to make their voices heard.


“It’s time for the people of Minnesota to speak up and say clean water is more important than the
soap industry’s contribution to certain politicians.”


But if Minnesota passes the ban, what would happen? Would major detergent manufacturers
make special dishwasher soap just to sell in one state? Minnesota lawmaker Ray Cox says look
at what happened as states started to ban phosphorus in laundry detergent.


“As soon as the scale tipped to where we had about 20 states that were banning it all the
manufacturers gave up the fight and they reformulated and nobody makes anything that has that
significant content anymore. So while you can say a state by state basis doesn’t make any sense,
on many things I think that’s the way we have to go.”


Cox says if Minnesota starts the ball rolling, it’ll just be a matter of time before phosphorus is
removed from dishwasher soap everywhere, which is why both sides are paying so much
attention to what happens in Minnesota.

Ice-Breakers Finish Up Duty

  • The Coast Guard cutter Sundew was built in 1944 in Duluth as a "buoy tender." In 1979, the Coast Guard had the ship's hull reinforced and beefed up its engine so the ship could double as an icebreaker. Photo by Chris Julin.

Cargo ships are moving on the Great Lakes, but Coast Guard icebreakers are still on duty on the
north side of the Lakes. The Coast Guard’s massive icebreaker, the “Mackinaw,” smashed ice
from its home in Michigan all the way across Lake Superior to Duluth. And the Coast Guard
cutter “Sundew” has been chipping away at the ice in Duluth for weeks. The Great Lakes Radio
Consortium’s Chris Julin has this report:


There’s a whiff of spring in the air in lots of places, but parts of Lake Superior are still covered
with ice. Cargo ships are leaving their berths where they spent the winter. But when the first
ships got ready to go, the ice on the Duluth Harbor was still two feet thick. That’s thick enough to
keep a ship locked in place.


The Coast Guard cutter Sundew carved a path through the ice so ships could leave.


(sound of chop, splash)


As the Sundew churns away, slabs of ice tip on edge under the bow. Each slab looks like the
floor of a single-car garage turned on edge. The Sundew will cut a swath several miles long, and
then come back along the same path. With each pass, the shipping lane gets a little bit wider.


Bev Havlik is the commanding officer on the Sundew.


“We’re taking out just little shaved bits of it at a time to make the ice chunks smaller. It’s like
sawing a log, just shaving off a bit of it at a time.”


“The Sundew wasn’t built as an icebreaker. It’s usual duty is tending buoys. The ship places, and
maintains about 200 navigational buoys on Lake Superior. But a couple decades ago, the Sundew
got some extra steel added to its hull, and a new, bigger engine. Since then, it’s done double duty
as an icebreaker.”


Commander Bev Havlik says the Sundew slices through thin ice like a butter knife. But in
thicker ice, like this stuff, the hull actually rides up on top of the ice and pushes down through it.
That’s why there are three mini-van-sized chunks of concrete on the ship’s deck. Each one weighs
12,000 pounds.
“It helps us bite into it with the bow, instead of riding up too high.” It keeps the weight down
forward more.”


A little bit like putting sandbags in the back of your pickup in the wintertime?


“It’s a similar sort of principle, right. It gives you the bite you need.”


Icebreaking is serious business. It gets ship traffic moving weeks before the ice melts. But
beyond that, Bev Havlik says it’s really fun.


“This is awesome. It’s the only job that I’d ever had where they pay us to come out and break
something.”


The Sundew is 180 feet long. That’s about the length of 10 canoes lined up end to end. It has
about 50 crew members. One of the junior crew members is usually at the wheel. The real
“driver” is an officer who’s standing 20 feet away, out on the deck through an open door. The
officer adjusts the ship’s speed, and calls out a steady stream of steering commands to the
“helmsman” — that’s the guy at the wheel.


(sound of Helsman)


“Right five-degrees rudder … steady as she goes, aye.”


Ensign Jason Frank is about to take his turn driving the Sundew. He wears a big rabbit fur hat
when he’s out on the deck driving the ship.


“We actually have face masks and goggles for when it really gets cold. It gets so cold out here
sometimes it feels like your eyes are going to freeze out, or something.”


(natural sound)


Jason Frank is halfway through his two-year stint on the Sundew. Then he’ll be stationed
somewhere else, and the Sundew will be removed from service. The ship was built in Duluth in
1944, and it’s retiring next year. Jason Frank wanted to work on the Sundew because aren’t many
ships like this still in service. On newer vessels, the officer driving the ship stands inside. And
here’s something right out of the movies – the Sundew has a big, brass steering wheel.


“Whereas with the new ships, most the new ships have just a little joystick. It’s very similar to
like a joystick you’d have maybe when you’re playing a computer game or something. All you
have to do is turn that joystick and the computer tells the rudder what to do. We’re actually
maneuvering the throttles, we’re actually driving. With the new ship, basically it has an
autopilot.”


The ice is melting in the Duluth Harbor, but it still clumps together on windy days and makes
trouble for ships. The Coast Guard cutter Sundew will stay on ice-breaking duty until the
weather warms up, and a good southwest wind pushes the rest of the ice out of the harbor into
Lake Superior.

New Herbicide Raises Safety Questions

Balance Pro gets into rivers and lakes too easily, and it could harm wildlife or even people. The
Great Lakes Radio Consortium’s Stephanie Hemphill reports:


Four years ago, the U.S. Environmental Protection Agency gave conditional approval for a new
weed-killer called Balance Pro. It’s made by a division of Bayer, the same company that makes
aspirin. But the EPA still had some worries.


EPA researchers thought the ingredients in Balance might accumulate in irrigation water. Some
people say, if it turns up in irrigation water, it could turn up in drinking water.


“Missouri has had drinking water reservoirs contaminated with this, and contaminated within the
first year of its use.”


Jannette Brimmer is with Minnesota Citizens for Environmental Advocacy. She worries that
Balance could turn into another environmental problem like atrazine. Atrazine is a commonly
used herbicide. It shows up in drinking water in many parts of the country, at very low levels.
Some studies show, even at those low levels, it’s causing deformities in the sexual organs of
frogs, which might be responsible for reductions in frog populations. And Brimmer wonders if
it might be affecting people too.


“In other words, small dosages at the wrong time in fetal development, pregnancy, in a kid, can
have significant impacts. So we have an opportunity to do the right thing before it gets into our
water, before it poses a health threat, before it’s a problem.”


The EPA doesn’t do any tests to find out whether herbicides affect the hormones of frogs or
people. The agency did conduct tests on the reproduction rates of aquatic animals, and found no
effects.


But the EPA does have one major concern — the effect Balance might have on other crops.
Officials worry if farmers use water polluted with Balance to irrigate crops like cabbage or
lettuce, the herbicide could hurt crop yields.


Both Michigan and Minnesota are trying to figure out how big a threat that might be. Dan
Stoddard, at the Minnesota Department of Agriculture, has been watching the field studies from
other states. He says the results are mixed.


Some of the studies looked at how much Balance got into water supplies. They found lower
concentrations than scientists originally predicted.


But some regions are more vulnerable than others, depending on the type of soil. Dan Stoddard
says areas with coarse or sandy soil, or shallow bedrock, are especially vulnerable.


“What has been considered is some requirements that would restrict use of the product in those
areas. But nonetheless it does have the potential to get into groundwater. What we would
require is additional monitoring to see whether that is in fact happening.”


Stoddard says he’s weighing the risk of polluted water against the benefits Balance might offer.
He’s hearing from companies that have been applying Balance in other states. They say, by
adding the new product to their arsenal, they can cut down on their use of other herbicides.


“If somebody uses the same type of pesticide or herbicide over a few years, weeds can become
resistant and what they wind up having to do is increase the concentration of that product. So
having a new chemistry allows lower application rates of the product.”


Wisconsin recently approved the use of Balance. But the Wisconsin Agriculture Department
there imposed so many restrictions, the company decided not to market it in the state. Bob
Olson is a farmer, active in the Wisconsin Corn Growers Association. He says his state is
putting him at a disadvantage compared to other farmers.


“It’s been registered in 17 other corn states. It’s just not been able to be registered here in
Wisconsin because of what we think are undue concerns. And the fact that we can find it in
increasingly smaller quantities. Simply because you can find something, doesn’t mean that level
is ever going to affect anyone.”


Michigan and Minnesota are planning to decide in time for spring planting whether to let
farmers use Balance in their states.

Canada’s Plans to Battle Farm Pollution

Seven people died and more than two thousand were made ill when E. coli bacteria contaminated Walkerton, Ontario’s water supply more than two years ago. The contamination came from cattle manure that had leeched into the ground. Now, the government of Ontario has come out with its plans in an attempt to prevent another tragedy like Walkerton.

Seven people died and more than two thousand were made ill when E. coli bacteria
contaminated Walkerton, Ontario’s water supply more than two years ago. The contamination came from cattle manure that had leeched into the ground. Now, the government of Ontario has come out with its plans in an attempt to prevent another tragedy like Walkerton. The Great Lakes Radio Consortium’s Dan Karpenchuk reports:


Ontario is considering two new laws to make its drinking water safer. The new regulations would affect everything from manure-spreading to barn construction.


The first, the Nutrient Management Act, would bind all farmers by the same curbs
on agricultural waste that contributed to the contamination of Walkerton’s water
supply.


The second, the Safe Drinking Water Act, would enshrine in law the right of people
in Ontario to clean and safe drinking water. It would also establish a water council to
conduct research, advise the government and set up a registry so consumers could
check the water quality in their area.


Paul Muldoon is with the Canadian Environmental Law Association. He says it’s too
early yet to say if the new rules go far enough..


“Our view is that we’re hopeful it’s going to do the right thing and we’re going to do anything in our power to point it in the right direction, once we see the details.”


There will likely be some opposition from farmers to the new rules. But they and the
municipalities will be given a chance to voice their concerns during public meetings
across Ontario this fall.
