The experts who identified the Ten Threats to the Great Lakes for us
say nonpoint source pollution is one of the worst threats. That’s
pollution that doesn’t come out of a pipe but instead is washed from
streets and farm fields… and lawns. Americans use at least three million of tons
of fertilizer on their lawns every year. But the same compounds that make for a lush,
green lawn can make a stinky, slimy mess when they get washed into lakes and rivers.

In our series, Ten Threats to the Great Lakes, we’ve been looking
at environmental problems affecting the health of the lakes. The Great
Lakes Radio Consortium’s Lester Graham is guiding us through the
issues one-by-one:


The experts who identified the Ten Threats to the Great Lakes for us
say nonpoint source pollution is one of the worst threats. That’s
pollution that doesn’t come out of a pipe but instead is washed from
streets and farm fields… and lawns. Americans use at least three million of tons
of fertilizer on their lawns every year. But the same compounds that make for a lush,
green lawn can make a stinky, slimy mess when they get washed into lakes and rivers.
Sarah Hulett looks at efforts to limit the amount of lawn chemicals that make their way
into the waterways:


When newspaper headlines decried the death of Lake Erie in the 1970’s, Americans got
familiar with a new enemy of the environment. Scientists named phosphorus the major
culprit in the lake’s decline. And the reaction went a long way toward cleaning up the
lake: billions of dollars went into upgrades for wastewater treatment plants to reduce
phosphorus from sewage. And phosphate detergents have been mostly phased out of use.


But now that regulators have gotten a handle on the phosphorus coming from the most
obvious sources, they’re left with a much more difficult task: reducing phosphorus from
countless smaller sources that together add up to a lot of pollution.


One of those sources is lawn fertilizer. And Glenn Short says it’s easy to see what
happens when that fertilizer gets washed into the lake where he lives.


(sound of ducks quacking and waves)


“You have this, like, green slime floating all over the top of the lake water. Just pops up
everywhere and it can fill the entire lake surface – especially in the calmer bays. It can be
just miserable for swimming and things like that.”


Short sits on the board of the Lake Sherwood Association, in southeast Michigan. His
neighbors asked him to lobby the township to pass a ban on phosphorus fertilizer to
reduce the algae that takes over the lake in the summers. But he says at first, he was
reluctant to do it.


“I’m like any other homeowner. I don’t want government telling me what to do with my
own property. If I want a really nice lawn, I felt that I should be able to have one.”


But he started doing some research. And he found that enough phosphorus will
eventually kill a lake.


“Over a period of time, you get more and more organic material growing, you kill it off,
you just start filling up your lake. And eventually you have no lake anymore. You just
have a wetland. Well, I like my lake. I mean, I live on a lake. I like to use my lake.”


So Short drafted an ordinance to ban fertilizers containing phosphorus, and his township
board passed it. Several other local governments in the region have also enacted limits or
outright bans. And the state of Minnesota has statewide limits on phosphorus fertilizers.


It’s an approach the landscape industry calls unnecessary.


Gary Eichen is with Mike’s Tree Surgeons in southeast Michigan. It’s a company that’s
signed onto an initiative aimed at environmentally responsible lawn care.

The company uses zero-phosphorus fertilizer on almost all the lawns it treats. Back at the
office, Eichen says the problem isn’t the chemicals – it’s that most homeowners don’t
know how to use them.


“They purchase from a source that is not educated in what the products are. He goes
home and starts going through this giant label on the back, and most of it might as well
be Egyptian hieroglyphics. He has no idea. So he ends up over-applying or incorrectly
applying.”


Eichen says there would be far fewer problems with runoff if homeowners left fertilizing
to the professionals. And he says it’s tough for the experts to stay in business when
there’s a patchwork of local ordinances to regulate chemicals like phosphorus.


But that’s exactly what the Environmental Protection Agency is asking communities to
do. Brad Garmon of the Michigan Environmental Council says that kind of bottom-up
regulation presents some challenges.


“It’s very difficult to see what’s working and what’s not, and to chart success. And I
know that a lot of the state programs are re-evaluating right now to see if the approach
they’ve been using over the last five or ten years has been working.”


It’ll take at least another five to ten years for Glenn Short to see the results of his
community’s phosphorus ban. The lake he lives on is part of a river system that
eventually dumps into Lake Erie. But he says just like that Great Lake, it’ll be worth the
wait and the effort to see his small lake bounce back to health.

Living on Top of a Fuel Pipeline

There are thousands of miles of pipelines in the U.S. constantly shuttling gas, oil, and other fuels from state to state. And although you might not realize the pipes might be under your property, the companies that own them have to keep the land above the pipes clear in case of an emergency. And over the past year, residents in some communities have been told they need to dig up trees and remove sheds to keep the path clear. In some cases, it’s more than just an inconvenience. It’s costly. But the homeowners aren’t all mad at the pipeline companies. They’re mad at the people who built their houses. The Great Lakes Radio Consortium’s Tom Weber reports:

There are thousands of miles of pipelines in the U.S., constantly shuttling gas, oil, and other fuels
from state to state. And although you might not realize the pipes might be under your property,
the companies that own them have to keep the land above the pipes clear in case of an
emergency. And over the past year, residents in some communities have been told they need to
dig up trees and remove sheds to keep the path clear. In some cases, it’s more than just an
inconvenience. It’s costly. But the homeowners aren’t all mad at the pipeline companies. They’re
mad at the people who built their houses. The Great Lakes Radio Consortium’s Tom Weber
reports:


Pipelines are a crucial link in the trip gasoline makes from the refinery to your car. They
crisscross the country, but most people don’t notice them.


Shelley Miller didn’t notice for years, even though she sleeps less than 30 feet from four of them
under her and her neighbors’ yard.


They carry gasoline, natural gas, heating oil and jet fuel.


In fact, more than 20-thousand gallons of fuel will race under Miller’s yard in St. Louis suburb of
St. Peters, Missouri by the time this story is over. She and her husband knew the pipes were there
when they bought the house… but they thought they were used for water or sewage.


The Millers didn’t realize they were wrong until last year… when Explorer Pipeline Company
came to make sure the land above its pipe was easily accessible.


For Miller, that meant two trees had to be removed, along with a shed that had become her
backyard’s equivalent of a kitchen junk drawer.


“We had planned to re-side our home. So we have siding we purchased one bit at a time to get to
that point. We don’t know where we’re going to put that. The lawn tractors, where we going to
put that? Where you going to move all this stuff?”


But that’s a small price to pay to make sure pipeline crews can get in fast if there’s an emergency.


Fred Low is a lawyer for Explorer Pipeline. He says companies like his have made an extra effort
in recent years to clear more urban or developed areas that have pipelines…


“In our industry, there have been some accidents in the past. There’s been national attention and
we want to do a better job. And to do a better job of running our pipeline we have to do a better
job maintaining our pipeline.”


And Miller understands that. She’s not mad at the companies because the pipelines were there
first. What upsets her is that 35 years ago, the city allowed the homes to be built so close to the
pipes.


More than 160 homes in St. Peters, Missouri have at least one pipeline in their backyard. But
Alderman Jerry Hollingsworth says it’s hard to blame the city.


“There were no guidelines for a city on how close to build a home next to a pipeline 35 years
ago. So somebody came in and said, ‘I’m going to build some houses in here’ and the city said
‘okay!'”


And many towns across the country did the same thing. Todd Swanstrom teaches Public Policy
at Saint Louis University. He says more and more suburbs might have to deal with pipelines as
they keep growing. Adding a subdivision or even a strip mall sounds nice if it adds to tax
revenue. But there’s also safety to think about…


“If there were an explosion and people lost their lives from a pipeline, I think it would be a very
different situation. As it is, it seems to be one of those issues that has largely gone under the
radar.”


But even if every growing suburb in the U.S. had rules for building on pipelines, there could still
be accidents… or deaths.


Ivel, Kentucky, San Jose, California and Whitehall, Pennsylvania are among communities where
pipelines have exploded in the past few years.


But Explorer Pipelines’ Fred Low says overall, pipeline companies have had an impressive safety
record.


“Being next to a pipeline isn’t necessarily that bad. There are literally millions of people who live
by pipelines. And we will not let structures be built on our easements, so that’s why we want to
keep them visible so we can find out if we’re being encroached upon.”


Since the St. Peters pipelines were laid in 1971, the city’s population has exploded and expanded
along the pipelines.


For Shelley Miller… her efforts now focus on raising awareness for others. She and her neighbors
have organized a group that pushes cities and towns to enact better rules for how land around the
pipes is developed, and how people are told of the lines before they buy a house.


St. Peters now has a law restricting development around pipelines. But that only does so much
for Miller as she goes to bed every night just a few feet from all that gasoline.


“When we hear a loud boom, yeah, we sit up in bed. We think about it. There’s a risk with
everything you do in life, but when you have to live with it on a 24/7 basis and you don’t know
what the next minute’s gonna bring, it stays on your mind.”
