There is also an article in the DM Register about this today, page 2 of the 
Metro Section.

Eight years ago Clive threatened to close the Flying J because its retention 
pond was leaking petroleum-contaminated water into Walnut Creek.

When the Flying J was built, we were assured this would be a "state of the 
art" holding pond and filter.  "State of the art" doesn't work when there is 
human error or neglect.  That was the case eight years ago--the equipment 
hadn't been monitored, cleaned or maintained.

Walnut Creek meanders through Clive's Greenbelt Park and the popular walking 
and biking trail is close to the creek.  As happened eight years ago, a 
trail user reported the odor and shiny film--but it wasn't noticed this time 
until it had already traveled to 103rd Street, which I would estimate to be 
about one mile from the Flying J.

The parking lot for this truck stop includes about 32 acres of asphalt, all 
sloping toward this retention pond which is probably less than 300 feet from 
the creek.  When this facility was proposed years ago, a staff person from 
then Governor Branstad's office attended the packed city council meeting to 
inform the crowd about the economic benefits that would result from the 
truck stop--such as jobs at the restaurant and gas station.  I am sure there 
were a lot of  pollutants in this flush down the creek, because the truck 
stop parking lot had been filled to capacity during the shut-down of the 
Interstate and the snow had been melting.  It's also probable that the snow 
from the lot had been piled in the corner near the retention pond, along 
with a lot of trash.  Sometimes the truckers dump spoiled loads in the lot.

As the article below mentions, Walnut Creek is a tributary to the Raccoon 
River, which is a source for drinking water for Des Moines and surrounding 
areas.  I was surprised to read that the Raccoon is only "occasionally" used 
as a source for drinking water.

At least 700 people signed petitions opposing the building of this facility 
and protested at several meetings, to no avail.

Another issue with the truck stop is the emissions from the trucks.  During 
certain winter conditions, diesel fumes float down the creek valley (east) 
and on at least one occasion, the fumes entered homes.  We live at least 1 
1/2 miles from the truck stop and have smelled the fumes outside our home 
and in our basement during extremely cold weather.
