Air Toxics Modeling Specialist (Natural Resource Specialist 4)

Oregon Department of Environmental Quality, Portland, Oregon

Job - Government

Close Date: 01/17/2019

The Oregon Department of Environmental Quality is now hiring several new positions for the Cleaner Air Oregon program, its innovative new program that evaluates and protects public health from industrial air toxics emissions. We are seeking dynamic and dedicated applicants to develop and implement this innovative new program.

The Cleaner Air Oregon program currently has a full-time opportunity for an Air Toxics Modeling Specialist (Natural Resource Specialist 4) to join this innovative team, advancing our agency's mission to protect and improve Oregon's environment. This position is located in Portland, Oregon. This position is limited duration through June 30, 2019 and may become permanent depending on the Budget.

About the Division:
The Air Quality Division is responsible for protecting Oregon's air quality through program planning and development, industrial permitting, asbestos control, wood smoke management, motor vehicle inspections, and control of other sources of air pollution. The Air Quality Division administers the federal air quality program, by delegation and approval from the EPA, and state requirements.

The Cleaner Air Oregon Section administers the requirements established by the Cleaner Air Oregon (Division 245) program rules. This program is a result of a rule-making process that was launched by Governor Kate Brown in April 2016, and was developed by the DEQ and the Oregon Health Authority to evaluate potential air toxics heath risks to people near industrial and commercial facilities, and reduce those risks.

The Cleaner Air Oregon program has lead responsibility to ensure the accurate assessment and reduction of air toxics using health based standards. This section is responsible for supporting completion of risk assessment, determining permitting and reporting requirements for sources assessed under program rules, and engaging local Oregon communities in the process. This section is primarily responsible for support and coordination of an air toxics program that is implemented by the Regions. This includes ongoing policy and guidance development, training, rule and statute revisions, performance monitoring, and oversight of the air toxics program.

What you will do!
The purpose of this position is to provide technical assessments and air quality analyses to support air toxics risk assessments at industrial facilities and other sources of air toxic emissions. The position will also participate in development and support of modeling and air quality analyses, workplan development, and modeling reviews that meet regional, local, and source-specific health-based air quality objectives. This work includes interaction with Federal and State Agencies, DEQ Headquarters and regional offices, and private sector stakeholders.

Technical assessment includes the use of dispersion modeling to evaluate air quality impacts on community, local, and regional scales from permitted industrial sources, other sources such as area and mobile sources, and sources from outside of the State. The assessment will also evaluate the effectiveness of strategies to mitigate impacts. This position provides high level technical assistance to staff and other agencies on Cleaner Air Oregon modeling policy issues, and provides support and assistance to regional offices to ensure that air quality analyses are consistent with national modeling guidance.

What's in it for you?
The opportunity to join a dynamic team of mission focused individuals tasked with providing high quality environmental data needed for understanding and protecting Oregon's air quality. Put your creative problem-solving and analytical skills to great use helping to keep Oregon green and our air clean. We offer full medical, dental, and vision health benefits with paid sick leave, vacation, personal leave, and 10 paid holidays a year. Public Service Loan Forgiveness Program: If you are employed by a government or not-for-profit organization, you may be able to receive loan forgiveness under the Public Service Loan Forgiveness Program (PSLF).

Working Conditions:
This person will commonly work in an office environment. Statewide travel and occasional evening and weekend meetings, and occasional extended work hours and weekend work, will be required. Field visits may be made to sites to observe, inspect, and evaluate permitted and unpermitted facilities' procedures and environmental impacts. During field activities, there may be exposure to pollutants, chemicals, contaminated soil, water, fumes, and airborne contaminants. Such conditions may require the use of personal safety equipment and protective clothing.

Serve as an air toxics and receptor modeling expert for the implementation of the Cleaner Air Oregon program and other air toxics programs.
Evaluate predicted air quality impacts from new and existing sources by reviewing modeling analyses prepared by third parties, evaluating facility plans, calculating and verifying emissions and emissions parameters, and evaluating plant site suitability, geography, and modeling receptor locations.
Use sophisticated computer dispersion models to predict impacts to assess and assure compliance with calculated risk assessment parameters, Risk Action Levels, and NSR/PSD ambient air quality standards.
Use modeling programs to provide impact estimates showing the effect of various proposed control strategies for inclusion in the Department's plans for achieving and maintaining Oregon's clean air standards.
Evaluate, develop, and adapt new dispersion and receptor models for use in air quality control strategy developments.
Provide modeling expertise in evaluating and predicting air quality impacts from existing sources, proposed new sources, and new modifications to existing sources.
Provide modeling knowledge and expertise to rule writers.
Assist rule writers in drafting rules pertaining to air quality modeling.
