A lawsuit says Oakland failed to consider the health impact of burning 3,000 bodies a year when it approved a crematorium in East Oakland.
Filed Wednesday by Communities for a Better Environment, it claims city planners wrongly designated the Neptune Society crematorium a general manufacturing facility that could be approved without a public hearing.
Residents say they are worried the crematorium will add to pollution that already exists because of a nearby freeway and airport.
Neptune Society spokesman Mike Miller tells the San Francisco Chronicle he hasn't seen the suit so he wouldn't comment.
The city approved a crematorium in 2012 after air quality management district said there wouldn't be enough pollution to put the community at risk.
