Section 316(b) of the Clean Water Act requires that the location, design, construction, and capacity of cooling water intake structures reflect the best technology available for minimizing adverse environmental impact. EPA embarked on three rulemaking phases to implement the statutory requirements.
The latest rulemaking effort began on April 20, 2011 when EPA published a proposed rule to protect fish from being killed at water intake structures that withdraw at least 2,000,000 gallons of water per day from waters of the United States and use at least 25% of the water they withdraw exclusively for cooling purposes. The proposed rule resulted from a request by EPA to the Fifth Circuit to take back portions of its cooling water rule relating to existing facilities (ConocoPhillips v. EPA, 5th Circuit No. 06-60662, July 23, 2010). Pursuant to a Settlement Agreement with the environmental group Riverkeeper and other organizations, EPA is required to issue the revised rule by July 27, 2012.
EPA has just published notice in the Federal Register presenting a summary of the significant new information and data EPA has received since its April 20, 2011 proposal and a discussion of possible revisions to the final rule that EPA is considering that were suggested by the data and comments. 77 Fed. Reg. 34315 (June 11, 2012)
During the comment period on the April 20, 2011 draft rule, EPA received more than 1,100 comment letters. It also received more than 80 documents containing new impingement and entrainment data for possible use in developing the final impingement mortality limitations.
EPA has now made the submitted information available for public review and has offered a 30-day comment period on the new information the agency will consider in making its decision on the final rule. Comments must be received on or before July 11, 2012.
A second key part of the Section 316(b) rulemaking, scheduled for publication on June 12, is a Notice of Data Availability which summarizes from a stated preference survey conducted by EPA after the April 20, 2011 proposed rule was published. EPA likewise is expected to allow a 30-day comment period on the preference survey summary and results.
To quote from the pre-publication version of the Federal Register notice, “. . . a stated preference survey attempts to gauge the value of an item through questions designed to mimic consumer decision-making in actual markets. . . . The stated preference survey estimates the value held by the public for ecosystem improvements based on the choices the surveyed members of the public make between hypothetical policy options and current conditions.” EPA will solicit comment on all aspects of the study and the appropriate role, if any, the study should play in EPA’s Section 316(b) rulemaking proceeding. EPA asks for comments even though it has not yet completed its statistical analysis of the survey data and is not in a position to determine whether the results of the survey will play a role in the benefits analysis for the final rule.
Given these two federal notices and the 30-day comment periods ending in the second week in July, it is hard for me to understand how EPA is going to comply with the court-required issuance date of new rulemaking by July 27. Stay tuned.
