Under general supervision, analyze and review air dispersion modeling using EPA approved software such as AERMOD and its suite of ancillary programs.  Support air construction permitting activities by ensuring discharges of pollutants into the air will be in compliance with the Clean Air Act.

Position is responsible for conducting air dispersion modeling in support of Air Construction Permit Section. Essential duties include:

• After an initial training period, work independently to review pre-construction air dispersion modeling to determine compliance with applicable regulations. 
• Conduct and/or review air quality computer modeling using various EPA-approved dispersion models such as AERMOD.  Review modeling protocols submitted by industry in support of construction permit applications.  Coordinate and gather source data necessary for conducting modeling.
• Prepare air dispersion modeling reports with enforceable requirements and conditions to assure compliance with the Nebraska Air Quality Regulations.
• Work with permit writers and applicants to obtain air dispersion modeling parameters and information needed to review, preform air dispersion modeling, and prepare reports for air construction permits. 
• Provide guidance and instruction to air quality construction permit writers on all aspects of air dispersion modeling. 
• Confer with and advise the regulated community on technical requirements of air dispersion modeling.
• Give presentations and provide testimony at public hearings in areas of responsibility. 
• Assist in regulatory planning and development of the permit program.
• Provide support and technical services to staff and the regulated community in the areas of air dispersion modeling data, emission inventory coordination, and characterization of emission points at facilities requesting construction permits.
• Participate in the development and revision of standard operating procedures, guidance documents, state implementation plans/strategies, air quality regulations and rulemaking.  Conduct research and compile data to support proposed changes.
• Duties may include working with a team of modeling, permit, and inventory specialists in implementing a consistent and efficient permit modeling program.
• As needed, review pre-construction permit applications for new and existing sources of air pollution and prepare draft permit documents ensuring compliance with applicable regulations
• As needed, review draft construction permits written by co-workers and contractors for accuracy, consistency, content, and enforceability.
