The Pollution Control Board withdrew the first-notice publication of the rulemaking proposal docketed as In the Matter of Section 27, Proposed Rules for Nitrogen Oxide (NOx) Emissions From Stationary Reciprocating Internal Combustion Engines and Turbines: Amendments to 35 Ill. Adm. Code Parts 211 and 217 (R07-19) and replaced it with an amended proposal. Because the Board is holding hearings in this docket on language that is substantively different from the language it proposed for first notice in June 2007, the Board is withdrawing the amendments currently at first notice and will proceed with its consideration of the amended proposal. http://www.cyberdriveillinois.com/departments/index/register/register_volume32_issue18.pdf pp. 7230-7231.
