Notice of Determination

Ottawa International Airport – April 26, 2023 – The Ottawa International Airport Authority (OIAA) has determined that if the proposed Alt Hotel Ottawa Airport construction project advances, it is unlikely to cause significant adverse environmental effects if the following mitigation measures are to be implemented:

General Construction Mitigation Measures

• Establish and follow a traffic control plan.
• Follow established industry construction mitigation measures.
• Limit stormwater run-off to pre-development rates by using infiltration and containment measures.
• Control stormwater quality using engineering measures (on-site underground tanks/chambers and released in a controlled manner).
• Establish and follow a waste management program.
• Complete equipment fueling and maintenance in designated areas where spill mitigations measures have been implemented.
• Use on-site sediment control measures, such as filter fabric fences and sediment containment traps to prevent migration of sediments from the property once the existing surface conditions are disturbed by construction.
• Install a building interior oil/water separator.
• Develop and follow a construction spill response plan.

Operational Mitigation Measures

• Install a building interior oil trap for the restaurant.
• Develop and follow a construction spill response plan.
• Develop a spill mitigation and response plan for site operations. 

The OIAA is satisfied that advancing this potential project is not likely to cause significant adverse environmental effects.

Therefore, the OIAA may support the project, exercise any power, perform any duty or function, or provide financial assistance to enable construction to be carried out in whole or in part.
