The Environment and Conservation Agency proposed to add Tenn. Admin. Code §0400.40.15, Biosolids Management, to promulgate rules for land application of biosolids. The rules are substantially similar to federal regulations, which the state has no authority to enforce. There will be public hearings July 23, 24, 30 & 31, 2012, and the deadline for comment is September 7. See http://state.tn.us/sos/rules_filings/05-13-12.pdf.
