EQ was retained to serve as a technical and regulatory consultant in all matters relating to air pollution control at a major chemical facility. As participants with project teams on two independent plant expansion projects, EQ provided advice and a technical critique of proposed operations and emission control measures. We held the lead position in preparing air permit applications and technical support documentation for these projects. In support of these projects, EQ performed VOC emission calculations for various pieces of equipment, including reactor vessels, paint production lines, and organic liquid storage tanks. We performed air dispersion modeling analyses of fenceline toxic air contaminant impacts for compliance with Ohio EPA's Toxic Guidance Policy, and we provided in-depth training to the plant engineering staff regarding new source air permitting and other pertinent regulatory issues within the plant. EQ then prepared all emission calculations and technical support documentation for Ohio EPA PTI and PTO applications for miscellaneous modifications to the Resin II facility.

EQ provided air dispersion and emission characterization modeling for multiple chemicals under the Chemical Accident Program Provisions of Section 112(r) of the Clean Air Act Amendments of 1990. Working under the direction of the client's corporate office at sites in CA, GA, IA, KS, LA, NC, OH, and WI, we provided a technical review of the 112(r) regulations with a subsequent characterization of each site containing a list of chemicals and methods of storage, transfer, and use, as well as documentation of impact areas, populations exposed, and affected sensitive residential, commercial, and environmental receptors. Both worst-case and accidental release modeling were performed for multiple chemicals listed under 112(r) provisions. Modeling analysis was performed using the EPA offsite consequence analysis techniques and the PHAST Model.

EQ performed dispersion modeling of NOX emissions resulting from process and facility changes. These changes resulted in new sources of NOX emissions and the shutdown of other sources. Modeling was performed using the ISCST3 Model that took into account both new sources and shutdown sources in a net ambient impact analysis. All offsite concentrations were less than half of the PSD increment for NOX as specified by EPA as a target value for increment analysis.

Also, EQ prepared several PSD permit submittals for this manufacturing facility as part of their site selection strategy for a new mini-mill. Potential sites were in Ohio, Michigan, Indiana, and Tennessee. EQ determined the permit dispersion modeling requirements in each state and performed PSD and NAAQS modeling for each site. EQ assisted in preparing the PSD permit application.

EQ's multidisciplinary staff provide key services covering the total spectrum of your environmental engineering requirements from project planning to complex site assessment/remediation projects. This listing contains just a few of the projects that EQ has completed for our clients.
