PREVENTION OF SIGNIFICANT DETERIORATION AND NEW SOURCE REVIEW One of the most complicated federal regulatory programs under the Clean Air Act is Prevention of Significant Deterioration (PSD) or New Source Review (NSR). PSD is generally applicable to large facilities in areas in attainment with National Ambient Air Quality Standards, and NSR is generally applicable in non-attainment areas. The regulatory requirements and procedures are similar. ECCI engineers have completed PSD/NSR projects in multiple states for industry sectors including petroleum and soybean oil refining, hazardous waste combustion, mining and mineral processing, appliance manufacturing, rocket manufacturing, furniture manufacturing, wood product manufacturing, saw mills, aluminum manufacturing, specialty chemical manufacturing, electrical components manufacturing, steel and plastic structural component manufacturing, food processing, electrical generation, printing and steel products manufacturing. ECCI engineers are well versed in all aspects of air dispersion modeling, emission netting, selection of best available control technology (BACT), BACT avoidance through cost benefit analysis, and PSD avoidance. ECCI engineers determine the facility business needs, then tailors the project to achieve the required production goals on the schedule needed in the most cost effective manner. Example Projects: 3M – Little Rock, Arkansas ECCI engineers completed complex air dispersion modeling for this mining and roofing aggregate production facility. Cost-effective air pollution controls were selected based upon ECCI technical assessments. All PSD triggers were avoided. Modeling combined measured emission rates, and actual ambient monitoring results.
Whirlpool Corporation – Fort Smith, Arkansas ECCI managers completed a system to establish a very flexible compliance program to allow use of a wide range of surface coatings. The project was awarded a Westinghouse silver medal for leadership in environmental excellence with two ECCI staff included as individual recipients.
Ciba Specialty Chemicals – West Memphis, Arkansas ECCI engineers prepared Title V and PSD permit applications which achieved significant production increases. Cost effective air pollution control equip-ment was selected to avoid PSD triggers and greatly shorten construction delays. Permit limits were developed based upon maximum flexibility to produce multiple products as the market dictates for the specialty chemical manufacturing facility.
Lion Oil – El Dorado, Arkansas ECCI completed Title V and PSD permit applications for this oil refinery located within city limits. Modeling successfully addressed numerous complex ambient air issues. Permits allow maximum production and flexibility between process vessels. The facility is subject to multiple NESHAP rules with MACT standards in place.
