[September 02, 2014]  SPRINGFIELD – The Illinois Department of Natural Resources (IDNR) has delivered revised rules to implement the Hydraulic Fracturing Regulatory Act. The revised rules were submitted to the Illinois General Assembly’s Joint Committee on Administrative Rules (JCAR) for a required second public notice period.  

Based on a record level of public participation following release the first draft last fall, the IDNR has substantially strengthened and clarified several sections of the proposed rules. Passage of the HFRA and the subsequent rulemaking process generated an unprecedented amount of feedback. Five public hearings were held around the state, and the agency received more than 31,000 comments amounting to 43,000 pages from members of the public, units of local government, environmental organizations and industry. The annotated copy of the revised rules, including comments and the agency’s responses to each issue area, can be found at:

“As the agency charged with standing up a brand new regulatory program, it was important that our staff took the time needed to consider all the public feedback and do the job right,” said IDNR Director Marc Miller. “We believe the revised rules submitted to JCAR today accurately reflect the intent of the law, and take into account the concerns of our constituents.”

Following the start of the second public notice period, JCAR has 45 days to consider the proposed regulations. JCAR can request an additional 45 days. By delivering the revised rules in time for the next scheduled JCAR meeting on Sept. 16, IDNR has insured that JCAR has adequate time to complete its work. Rules must be adopted within one year of first notice, which for this rulemaking will be Nov. 15, 2014.
