Community gardeners in Detroit are angry about new permit requirements for gardening on city-owned lots.

Reit Schumack heads an organization on the city’s west side called Neighbors Building Brightmoor, which puts in gardens, wildflower stands and pocket parks on dozens of city lots. Schumack says the new rules include a ban on bringing in new soil or compost, unless the city grants lot-by-lot permission:

"If we have to ask for every single lot for everything that we want to do, we have to fill in a paper, bring it to the city, wait for their response before we do anything… by that time the season is over, and you’re stuck with a lot full of weeds."

MARINE CITY, Mich. (AP) - Public health officials in St. Clair County are expanding their investigation into whether environmental or other factors could be responsible for a rare form of kidney cancer diagnosed in children in the Marine City area.

The investigation started this year looking into five cases of Wilms' tumor since 2007 in southeastern St. Clair County. The Times Herald of Port Huron reported Thursday that eight cases now are included, including two in the Port Huron area and one in Richmond.

Officials say another case in the St. Clair Shores area isn't being considered because it's too far away.

Marine City, which is located about 40 miles northeast of Detroit, has industrial plants and is about 10 miles from petrochemical plants in Sarnia, Ontario. But health officials say there's no established link.

Enbridge Inc. says it will spend $286 million to replace 75 miles of pipeline in Indiana and Michigan after a 2010 break that spilled at least 800,000 gallons of oil into the Kalamazoo River system.

The Houston-based company said Thursday the work is planned next year on the pipeline, which runs from Griffin, Ind., to Sarnia, Ontario.

The company says it's already replaced 14 segments covering 1.7 miles in southeastern Michigan and has installed a new line under the St. Clair River.

The new work includes five miles of pipeline downstream from each of two pump stations in Indiana and three in Michigan, as well as 50 miles of pipeline downstream from the Stockbridge station and terminal, about 55 miles west of Detroit.

The legal battle over a proposed expansion of a coal-fired power plant in Holland is not over yet. The State of Michigan granted the city the necessary air quality permit in February, following years of delays. But now a number of environmental groups are teaming up and bringing the issue back to court.

A new University of Michigan study in the journal Health Affairs finds 62% of public schools in the state are located in places with high levels of air pollution from industries.

Paul Mohai is one of the study’s authors.

“Often schools are located in more polluted parts of their respective school districts.”

He says schools need a lot of land... and land is expensive but money is tight.

“There’s probably quite an economic pressure to put schools where land values are low, and those may be near highways or industrial facilities or that otherwise are polluted.”

Mohai says Michigan has no formal policy that requires school boards to consider the environmental quality of an area for a new school.

William Mayes is the executive director of the Michigan Association of School Administrators. He says school boards do consider pollution when they’re finding new sites for schools.

“You know, intelligent people are thinking about this. The bottom line is you look at where your community is expanding, where your community is growing, and you seek the most economical and safe property you can to build a school.”

Mayes says people are drawn to where the jobs are, and that’s often near industries, and industries pollute.
