NESHAP and NSPS Rules For Portland Cement Manufacturing.

After reconsideration, US EPA is proposing to amend the NESHAP and NSPS rules relating to Portland cement manufacturing. On September 9, 2010 EPA promulgated final amendments to the Portland cement NESHAP and NSPS rules regulating emissions of air toxics and criteria pollutants. These amendments applied to all cement kilns that do not burn waste materials. Cement kilns that burn waste are regulated by separate rules covering hazardous waste combustors and commercial and industrial solid waste incinerators.

Subsequent to promulgation of the September 9 rule, EPA received four petitions for reconsideration, two from environmental groups and two from the Portland cement industry. EPA also received 20 petitions for judicial review of the September 9, 2010 final action.

At present, EPA is issuing a notice stating how the agency plans to respond to the petitions. If the agency response includes any rule amendments, EPA plans to propose and finalize those amendments as additional stages of the action. The amendment may also include corrections and clarifications discovered to be necessary after promulgation of the September 2010 amendments. However, EPA does not anticipate any significant changes in rule stringency as part of this action.
