On March 29, the comment period ended for Environmental Protection Agency (EPA) draft standards for environmental data collection, production, and use by non-agency organizations. The drafts were first released in December 2012, and the comment period was extended twice. Most of the comments said the standards would place a burden on states by straining resources and by delaying other permits. The Michigan Department of Environmental Quality responded that the EPA did not provide rationale or justification for the standards, and the Computer Sciences Corp. (CSC) said the standards would create more confusion.
