Assessment Topic

The Environmental Protection Agency (EPA) is required by Section 111(b)(1)(B) of the CAA to review and, if appropriate, revise existing NSPS at least every 8 years. The purpose of an NSPS review is to determine if the standards reflect BDT. The nitric acid NSPS (part 60, subpart G) has been reviewed in the past, but the last review was more than 8 years ago. As a result of this, EPA received a citizen suit from Sierra Club and Environmental Integrity Project prompting a review of the standards.
Section 111(b)(1)(B) of the CAA requires EPA to periodically review and revise the standards of performance, as necessary, to reflect improvements in methods for reducing emissions. EPA is currently reviewing the nitric acid manufacturing NSPS and has noted that improvements in technology allow emissions to be better controlled than the current NSPS requires. In light of this review, EPA is revising the current NSPS. These revisions include tightening the current nitrogen oxides (NOx) limit set back in 1971 for plants that manufacture nitric acid. The revised NSPS will be promulgated on May 14, 2012 under a court-order.

This economic impact analysis (EIA) contains four other sections. Section 2 is a profile of the nitric acid manufacturing industry. It provides the reader with a basic understanding of the structure of the nitric acid production process, and characterizes nitric acid suppliers and demanders. Section 3 describes the estimated costs that the nitric acid industry would incur with the promulgation of the revised regulations for the industry. Section 4 analyzes the impacts of these costs on the industry, including potential impacts on small businesses owning nitric acid production facilities. Section 5 provides conclusions.
