Environmental Regulatory Round Up

  • The lime industry has joined a host of other facilities subject to MACT standards. EPA promulgated the Lime Manufacturing MACT in January 2004. With this regulation, lime manufacturers have burdens related to initial performance testing, ongoing monitoring, and increased recordkeeping and reporting requirements.
  • Lime facilities must also address new requirements related to Spill Prevention, Control, and Countermeasure (SPCC) plan development. In December 2008, EPA published revisions to the rule that become effective in February 2009.
  • In addition, aggregates facilities continue to contend with New Source Performance Standards requirements under 40 CFR 60, Section OOO, which applies to nonmetallic mineral processing plants. Changes to NSPS Subpart OOO were proposed by the EPA in April 2008.

Project Profiles

  • Trinity provides comprehensive environmental management services for a national aggregates company. For several of the company’s facilities, Trinity maintains all environmental records, provides monthly management services including bi-monthly meetings, and completes annual permitting and reporting requirements, annual emissions reporting, water permit renewals, annual mine reports, and site registration renewals.
  • Trinity has prepared and aided various clients in obtaining air permits for modern vertical shaft lime kilns at multiple locations throughout the U.S. Trinity prepared all elements of the air permitting application including BACT, NSR applicability, and air dispersion modeling in these cases. These projects have often required complex strategies to manage time and control equipment costs and long-term compliance risks for our clients. In each of these situations, Trinity’s experience with the lime manufacturing industry and its processes, combined with a deep understanding of the local and federal regulations and policies under the CAA, provided invaluable insights in successfully completing and obtaining all of the necessary preconstruction air permits.
  • For a national lime company, Trinity completed a preliminary air dispersion modeling analysis to determine the existing impact that the facility has on the National Ambient Air Quality Standards. This information aided in future permitting and expansion decisions.
