Organic material management is regulated (i.e., siting, permitting, and management) at the state level, except for biosolids and animal manures.

States have assumed the lead role in regulating composting facilities. Composting facilities may need approval from the state before operating. The permit requirements for composting facilities vary among states. Examples of topics covered in the permitting process include: a detailed facility design, operating plans, a description of incoming materials, the amount and types of residue to be generated in the plant, monitoring plans, potential environmental releases, landfills to be used, and potential markets for the compost. Please visit the EPA's "Where You Live" page to find information about regional and state composting programs.

On the federal level, the Standards for the Use or Disposal of Sewage Sludge (40 CFR Part 503 under the Clean Water Act ) was published in the Federal Register (58 FR 9248 to 9404) on February 19, 1993. This act pertains to land application (and biosolids composting), surface disposal, and combustion of biosolids sewage sludge. Many of the standards promulgated in this rule can be applicable to municipal solid waste compost. For more information about this regulation, please go to EPA's Biosolids Page. Below is the Standard For The Use Or Disposal Of Sewage Sludge broken into individual chapters and offered in text or pdf format as taken from the National Archives and Records Administration's Code of Federal Regulations.
