Marnie Freer Principal

Marnie Freer is a Limited Engineering Licensee with more than twenty years of environmental consulting and project management experience. She is a member of the MOECC Air Practitioners Group providing technical input to the MOECC for the implementation of O.Reg.419. Her expertise is focused on regulatory compliance strategy, complex emission inventory development, air dispersion modelling and air approvals, and emerging regulation impact.

Project Experience

Environmental Compliance Approvals (ECA), Licenses and Permits

Ms. Freer has prepared applications for Environmental Compliance Approvals (ECAs) for multiple manufacturing facilities. Preparation of the applications involved:

  • Development of strategic approaches to address future operational flexibility.
  • Preparation of emission estimates using emission factors, mass balance and incorporation of stack testing data
  • Conducting air dispersion modelling of contaminants.
  • Completing solution development work in response to compliance challenges
  • Co-ordination of Acoustic Assessments.
  • Negotiations with MECP to ensure appropriate terms and conditions are in the ECA.

Projects have included:

  • Application for ECA with Limited Operational Flexibility (ECA with LOF) for a petrochemical manufacturing facility, including a Combined Assessment of Modeling and Monitoring (CAMM)
  • Application for ECA with Limited Operational Flexibility for a cogeneration facility including enhanced air dispersion modeling to reflect complex building geometry and noise abatement program
  • Application for ECA with LOF for a Liquefied Natural Gas facility within a refinery in Ontario
  • Renewal of an ECA with Limited Operational Flexibility for a carbon black manufacturing facility to allow for future production modifications. The application included multiple operating scenarios and related modeling.

Air Dispersion Modelling

Ms. Freer has performed air dispersion modeling studies using regulatory models including SCREEN3 and AERMOD as well as the Ontario regulatory air model. Most of these studies have required the development and assessment of potential solution options to maintain or obtain compliance with regulatory standards. Facilities assessed include chemical manufacturing, carbon black manufacturing; glass fiber insulation manufacturing; glass textile manufacturing; etc.

Selected projects have included:

  • Refined dispersion modeling analyses of manufacturing facilities in Ontario using AERMOD. These projects involved modeling the plant under multiple conditions, identifying possible solution options and subsequent modeling of various solution development scenarios.
  • A dispersion modeling analysis of an Ontario petrochemical refinery in conjunction with an application for an ECA with Limited Operational Flexibility. The project involved modeling of the facility using a defined meteorological data set and comparing the results to provincial standards.
  • A comprehensive odor modeling study of a manufacturing facility using AERMOD and SCREEN3. This project involved modeling numerous combinations of sources contributing to odorous emissions, and further solution development modeling to identify effective abatement solutions.

Emission Inventories

Ms. Freer has prepared Emission Summary and Dispersion Modeling Reports to support ECA applications and prepared annual emission calculations and reports for NPRI; Federal and Provincial GHG reporting; and Ontario’s Toxics Reduction Reporting requirements.

Some of her clients include:

  • Crude Oil Refineries
  • Styrene manufacturing facility located in Sarnia, Ontario
  • Glass fiber insulation manufacturing facility in Alberta
  • Carbon black facility Sarnia, Ontario
  • Chemical manufacturing facilities located in Southwestern Ontario
  • Steel Mini Mill based in Cambridge, Ontario

Data Management

Ms. Freer has extensive experience in the management of Environmental, Health and Safety data. Selected projects include:

  • Implementation and administration of the LEHDER Environmental Information Management Service (LEIMS) database. LEIMS is a service which consists of a consolidated custom data management system, an open database structure and a graphical interface for data interpretation and communication. It is used to manage air emission data to support the preparation of Emission Summary and Dispersion Modeling Reports and to facilitate the preparation of NPRI, regulatory reports and ECA Application data.
  • Creation of a database for recording and tracking classifications of dangerous goods under 4 modes of transport. The project included the mapping of the table structure, query development, input forms and reports creation. Data was also migrated from the existing system to the LEHDER database.

Hazardous Materials Management

Ms. Freer has conducted legislated, site-specific training programs for TDG, Ontario Regulation 347(558) [Waste], general safety and emergency/spill response. Other related projects include:

  • Managed an SDS creation project for an international pharmaceutical company. This included the generation of 2500 product SDSs and population and management of the corporate database system. Liaised with international facility contacts and coordinated the LEHDER creation team.
  • Implemented an SDS database system for a North American chemical manufacturing corporation. This included design and code creation for algorithms to satisfy Canadian, American, and European regulations and production of product and intermediate SDSs.
